If a certain number is added to both the numerator and denominator of the fraction 7 6 76, the result is 3 2 32 . find the number.

Answers

Assuming that the right statement is that if a certain number is added to both the numerator and the numerator of the fraction 7/6, the result is 3/2, find the number, the solution if found in this way:

Call x the number (certain number)

=> (7+x) / (6 +x ) = 3/2

=> (7 + x)*2 = 3*(6 + x)

=> 14 + 2x = 18 + 3x

=> 14 - 18 = 3x - 2x

=> - 4 = x

How to solve for a side of a right triangle when you only know one side?

Answers

Well if you know the area of the triangle you can use that to find the other lengths or else just use the Pythagorean Theroem.

Hope I helped :)
If you only know one side, then that's not enough information to solve for any other part of a triangle. You also need to know the measures of the angles at each end of it. In a right triangle, that means you need to know one of the acute angles (since you already know the right angle).


The functions graphed show the snowfall, in inches, in two cities after x hours.

Select each correct answer.



Middletown had a faster rate of snowfall.

Smithville had a faster rate of snowfall.

Snow fell in Smithville at a rate of 4 inches per hour.

Middletown already had snow on the ground at the beginning of the storm.

Answers

The answer Fam is............. Smithville had a faster rate of snowfall., And..Snow fell in Smithville at a rate of 4 inches per hour.

we know that

the formula to calculate the slope between two points is equal to

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

in this problem

the rate of snowfall is equal to the slope of the linear equation

so

Let

x-------> the time in hours

y---------> the snowfall in inches

Step 1

Find the slope of the line of the Smithville city

Let

[tex]A(0,0)\\B(5,20)[/tex]

substitute the values in the formula above

[tex]m=\frac{20-0}{5-0}[/tex]

[tex]m=4\frac{inches}{hour}[/tex]

Step 2

Find the slope of the line of the Middletown city

Let

[tex]A(0,0)\\B(5,15)[/tex]

substitute the values in the formula above

[tex]m=\frac{15-0}{5-0}[/tex]

[tex]m=3\frac{inches}{hour}[/tex]

Step 3

Verify the statements

case A) Middletown had a faster rate of snowfall

The statement is False

Because Smithville had a faster rate of snowfall with [tex]4\frac{inches}{hour}[/tex]

case B) Smithville had a faster rate of snowfall

The statement is True

case C) Snow fell in Smithville at a rate of 4 inches per hour

The statement is True

case D) Middletown already had snow on the ground at the beginning of the storm

The statement is False

Because at the beginning of the storm the value of the snow is equal to zero

therefore

the answer is

Smithville had a faster rate of snowfall

Snow fell in Smithville at a rate of 4 inches per hour

Justin is constructing a line through point Q that is perpendicular to line n. He has already constructed the arcs shown. He places his compass on point B to construct an arc. What must be true about the width of the compass opening when Justin draws the arc?
A .It must be wider than when he constructed the arc centered at point A.

B It must be the same as when he constructed the arc centered at point A.

C. It must be equal to BQ .

D.It must be equal to AB .


Answers

B. It must be the same as when he constructed the arc centered at point A. This problem would be a lot easier if you had actually supplied the diagram with the "arcs shown". But thankfully, with a few assumptions, the solution can be determined. Usually when constructing a perpendicular to a line through a specified point, you first use a compass centered on the point to strike a couple of arcs on the line on both sides of the point, so that you define two points that are equal distance from the desired intersection point for the perpendicular. Then you increase the radius of the compass and using that setting, construct an arc above the line passing through the area that the perpendicular will go. And you repeat that using the same compass settings on the second arc constructed. This will define a point such that you'll create two right triangles that are reflections of each other. With that in mind, let's look closely at your problem to deduce the information that's missing. "... places his compass on point B ..." Since he's not placing the compass on point Q, that would imply that the two points on the line have already been constructed and that point B is one of those 2 points. So let's look at the available choices and see what makes sense. A .It must be wider than when he constructed the arc centered at point A. Not good. Since this implies that the arc centered on point A has been constructed, then it's a safe assumption that points A and B are the two points defined by the initial pair of arcs constructed that intersect the line and are centered around point Q. If that's the case, then the arc centered around point B must match exactly the setting used for the arc centered on point A. So this is the wrong answer. B It must be the same as when he constructed the arc centered at point A. Perfect! Look at the description of creating a perpendicular at the top of this answer. This is the correct answer. C. It must be equal to BQ. Nope. If this were the case, the newly created arc would simply pass through point Q and never intersect the arc centered on point A. So it's wrong. D.It must be equal to AB. Sorta. The setting here would work IF that's also the setting used for the arc centered on A. But that's not guaranteed in the description above and as such, this is wrong.

The sum of two numbers is 67 . the larger number is 5 more than the smaller number. what are the numbers?

Answers

Call the numbers x and y. According to the first sentence, x + y = 67. According to the second sentence, x = y + 5. You can combine these two equations to find the values of these variables:

x + y = 67
(y + 5) + y= 67
2y = 62
y = 31

You can use this to find x by plugging in y to either original equation:

x = y + 5
x = 31 + 5
x = 36

Two cars leave town going in opposite directions. one car is traveling 55 miles per hour (mph), and the other car is traveling 40 mph. how long will it take before the cars are 285 miles apart?

Answers

The distance, d, traveled by a car going at speed, s, in time, t, is
d = st

Car 1 travels distance 1, d1, at s1 = 55 mph, for t1 time.
Car 2 travels distance 2, d2, at s2 = 40 mph, for t2 time.

The two distances add to 285 miles, so
d1 + d2 = 285
The two times are equal, so t1 = t2 = t

d1 = 55t1
d2 = 40t2

d1 = 55t
d2 = 40t

d1 + d2 = 55t + 40t

d = 95t

285 = 95t

95t = 285

t = 3

Answer: It will take 3 hours.

Note:
This problem shows you that if two cars are traveling along the same line in opposite directions, the speed at which they are distancing themselves is the sum of the two speeds. We can solve the problem in a simpler way:

55 mph + 40 mph = 95 mph

d = st

285 = 95t

t = 3

Answer: 3 hours.

A share of stock in the Lofty Cheese Company is quoted at 251/4. Suppose you hold 30 shares of that stock, which you bought at 201/4. If you sell your stock at 251/4, how much profit do you get or lose?

Answers

You'll make a profit of $150.

To calculate the profit from buying and selling stocks, subtract the buying price per share from the selling price per share and then multiply by the number of shares. For 30 shares of the Lofty Cheese Company stock, the profit would total $150.

The question involves calculating the profit from buying and selling stocks. When selling the Lofty Cheese Company stock quoted at 251/4 per share, we need to calculate the profit based on the purchase price (201/4) and the selling price (251/4) for 30 shares.

To find the profit per share, subtract the buying price from the selling price:

Selling Price per Share = 251/4

Buying Price per Share = 201/4

Profit per Share = Selling Price - Buying Price = 251/4 - 201/4 = 5

Then, multiply the profit per share by the total number of shares:

Number of Shares = 30

Total Profit = Profit per Share times Number of Shares = 5 times 30 = 150

Therefore, you would realize a total profit of $150 by selling your 30 shares of the Lofty Cheese Company stock.

If this pizza was cut into 50 slices, what would be the area of each slice and the length of the crust for the slice? Explain what concepts of a circle these calculations related to.

Answers

1. 
a.
A secant line is a line which intersects the circle at 2 different points. 

A tangent line is a line which has only one point in common with the circle.

Check picture 1: The orange line s is a secant line, the blue line t is a tangent line.


b.
An inscribed angle is an angle formed by using 3 points of a circle. 

The main property of an inscribed angle is that its measure is half of the measure of the arc it intercepts.

Check picture 2: If  [tex]m(\angle KML)=\beta[/tex], then the measure of arc KL is [tex]2 \beta [/tex].

A central angle is an angle whose vertex is the center of the circle, and the 2 endpoints of the rays are points of the circle.

The main property is: the measure of the central angle is equal to the measure of the arc it intercepts. 

Check picture 2

2.
To construct the inscribed circle of a triangle, we first draw the 3 interior angle bisectors of the triangle.
They meet at a common point called the incenter, which is the center of the inscribed circle.
We open the compass, from the incenter, so that it touches one of the sides at only one point. We then draw the circle. (picture 3)

To draw the circumscribed circle, we first find the midpoints of each side. We then draw perpendicular segments through these (the midpoints.) They meet  at one common point, which is the circumcenter: the center of the circumscribed circle.
We open the compass from the circumcenter to one of the vertices of the triangle. We draw the circle, and see that it circumscribes the triangle.

(picture 4)

3.

Given an equation of a circle: [tex]x^2-2x+y^2+6y+6=0[/tex].

To determine the center and the radius of the equation we must write the above equation in the form :

                              [tex](x-a)^2+(y-b)^2=r^2[/tex].

Then, (a, b) is the center, and r is the radius of this circle. We do this process by completing the square.

Note that [tex]x^2-2x[/tex] becomes a perfect square by adding 1, and 
[tex]y^2+6y[/tex] becomes a perfect square by adding 9. 

Thus we have:

[tex]x^2-2x+y^2+6y+6=0\\\\(x^2-2x+1)+(y^2+6y+9)-4=0\\\\(x-1)^2+(y+3)^2=2^2[/tex]

Thus, the center is (1, -3), and the radius is 2.

4. Not complete


5.

The radius of the pizza is [tex]\displaystyle{ \frac{131}{2}ft=65.5ft [/tex].

The surface of a circle with radius r is given by the formula [tex]\displaystyle{  A=\pi r^2[/tex],
and the circumference is given by the formula C=2πr.

Thus, the area of the whole pizza is given by [tex]\displaystyle{ A=\pi r^2= \pi\cdot65.5^2=4290.25 \pi [/tex] (square ft).

Each of the 50 slices, has an area of [tex]\displaystyle{ \frac{4290.25 \pi}{50} =85.805 \pi [/tex] (square ft)

Notice that the perimeter (the crust) of a slice is made of 2 radii, and the arc-like part.
The arc is 1/50 of the circumference, so it is [tex] \displaystyle{\frac{2 \pi r}{50} = \frac{2\cdot65.5\cdot \pi }{50}= 2.62 \pi [/tex].

So the perimeter of one slice is 65.5+65.5+2.62π=131+2.62π

Final answer:

The differences between secant and tangent lines, and between inscribed and central angles, involve the number of intersection points with the circle and the position of the vertex, respectively. Constructing an inscribed circle involves finding the incenter, while a circumscribed circle requires finding the circumcenter. To find the center and radius of a circle using its equation, we use the standard form (x - h)² + (y - k)² = r².

Explanation:

Differences Between Secant Lines, Tangent Lines, Inscribed Angles, and Central Angles

A secant line is a line that intersects a circle at two points, while a tangent line touches the circle at exactly one point. An inscribed angle is an angle formed by two chords in a circle that meet at one point in the circle, whereas a central angle is an angle whose apex (vertex) is the center of the circle.

Constructing Inscribed and Circumscribed Circles in a Triangle

To construct an inscribed circle (incircle) of a triangle, draw the angle bisectors of the triangle's angles to find the incenter, and then use this point to draw the circle that touches all three sides of the triangle. For a circumscribed circle (circumcircle), draw the perpendicular bisectors of the triangle's sides and the point where they intersect will be the circumcenter; use this as the center to draw the circle that passes through all three vertices of the triangle.

Finding the Center and Radius of a Circle Using an Equation

Given a circle's equation in the standard form (x - h)² + (y - k)² = r², the center is at point (h, k), and the radius is the square root of r². For example, if we have the equation (x - 3)² + (y + 2)² = 16, the center is (3, -2) and the radius is 4 units.

Area and Length of the Crust of a Circular Pizza Slice

For the world's largest round pizza with a diameter of 131 feet, the radius would be 65.5 feet. The area of each slice is a fraction of the whole pizza's area, which can be found using the formula A = πR², and the length of the crust for the slice corresponds to the arc length of that slice.

Area of whole pizza = 3.14 * 65.5² ≈ 13478.2 ft²

Area of each slice = total area /50 = 13478.2/50 ≈ 269.5 ft²

Length of crust =  2πR * (slice area/total area)

= 2 * 3.14 * (1/50)

≈ 0.125 ft

A company plans to enclose three parallel rectangular areas for sorting returned goods. the three areas are within one large rectangular area and 10641064 yd of fencing is available. what is the largest total area that can be​ enclosed?

Answers

First get the perimeter

Perimeter: 2l + 2w = 1064 yd

 

The region inside the fence is the area

Area: A = lw

 

We need to solve the perimeter formula for either length or width.

2l + 2w = 1064 yd

2w = 1064 yd – 2l

W = 1064– 2l / 2

W = 532 – l

 

Now substitute than to the area formula

A = lw

A = l (532 – l)

A = 532 – l^2

 

Since the equation A represents a quadratic expression, rewritte the expression with the exponents in descending order

A(l) = -l^2 + 532l

 

Then look for the value of the x coordinate

 

l = -b/2a

l = -532/2(-1)

l = -532/-2

l = 266 yards

 

Plugging in the value into our calculation for area:

A(l) = -l^2 + 532

A(266) = -(266)^2 + 532 (266)

A(266) =  70756+ 141512

= 70756 square yards.

 

Thus the largest area that could encompass would be a square where each side has a length of 266 yards and a width of:


W = 532 – l

= 532 – 266

= 266

It should be noted that the largest total area that can be enclosed will be 70756 yards².

How to calculate the area.

Firstly, we have to calculate the perimeter. This will be:

2l + 2w = 1064 yd

Area: A = length × width

2l + 2w = 1064 yd

2w = 1064 yd – 2l

W = 1064– 2l / 2

W = 532 – l

Since Area = lw

A = l(532 – l)

A = 532 – l²

A(l) = -l² + 532l

l = -b/2a

l = -532/2(-1)

l = -532/-2

l = 266 yards

The length is 266 yards.

Area = -l² + 532

A( = -(266)² + 532 (266)

Area = 70756+ 141512

Area = 70756 yards²
