Starting at the same point, Tom and Juanita go biking in opposite directions. If Tom rides at a speed of 24 mph, and Juanita rides at a speed of 30 mph, how far apart will they be in 3 hours?

Answers

Answer 1
Final answer:

Tom and Juanita, starting from the same point and biking in opposite directions for 3 hours, will end up 162 miles apart.

Explanation:

Starting from the same point, Tom and Juanita go biking in opposite directions for 3 hours. From what we know, Tom rides at a speed of 24 mph and Juanita rides at a speed of 30 mph.

When an object moves in one direction, its distance travelled is calculated from the formula distance = speed x time. This is because speed is described as the distance travelled per unit time. In this case, Tom travels 24 miles in 1 hour, so in 3 hours, he will cover 24 mph x 3 hours = 72 miles. Juanita will cover 30 mph x 3 hours = 90 miles.

Because they are moving in opposite directions, these distances add together. So in 3 hours, Tom and Juanita will be 72 miles + 90 miles = 162 miles apart.

Answer 2

Tom and Juanita will be 162 miles apart after 3 hours of biking in opposite directions at their respective speeds.

To solve this problem, we can use the formula for distance, which is the product of speed and time.

Since Tom and Juanita are riding in opposite directions, their distances from the starting point will add up to the total distance between them after a certain amount of time.

The correct total distance apart should be calculated as follows:

 Total distance apart = Distance of Tom + Distance of Juanita Total distance apart = 72 miles + 90 miles = 162 miles Upon re-evaluating the calculation, we find that the total distance apart is indeed 162 miles, not 156 miles as initially stated.

The correct final answer is:

 Total distance apart = 162 miles Therefore, Tom and Juanita will be 162 miles apart after 3 hours of biking in opposite directions at their respective speeds.

y=4x + 3 and 2x + y = 39 how can I find the answer

Answers

Answer:

x=6

Step-by-step explanation:

2x+(4x+3)=39

2x+4x+3=39

6x+3=39

6x=39-3

6x=36

x=36÷6

x=6

Final answer:

Solving the system of equations y = 4x + 3 and 2x + y = 39, we first substitute y from the first equation into the second. Simplifying, we find x = 6. Substituting x = 6 into the first equation, we find y = 27. Therefore, the solution is x = 6, y = 27.

Explanation:

To find the answer to this system of linear equations using substitution method, we first need to make y the subject of the first equation. From y = 4x + 3, we then substitute y in the second equation, thereby getting 2x + 4x + 3 = 39.

After simplifying, the combined equation becomes 6x + 3 = 39. We then isolate x by subtracting 3 from both sides, giving 6x = 36, and therefore x = 6.

To find y, substitute x = 6 into the first equation, y = 4x + 3. Thus, y = 4*6 + 3, which gives y = 27.

So, for the equations y = 4x + 3 and 2x + y = 39, the solution is x = 6, y = 27.

A cylindrical roller 2.5 m in length, 1.5 m in radius when rolled on a road was found to cover the area of 16500 m2 . How many revolutions does it make ?

Answers

Answer:

701 revolutions

Step-by-step explanation:

Given: Length= 2.5 m

            Radius= 1.5 m

            Area covered by roller= 16500 m²

Now, finding the Lateral surface area of cylinder to know area covered by roller in one revolution of cylindrical roller.

Remember; Lateral surface area of an object is the measurement of the area of all sides excluding area of base and its top.

Formula; Lateral surface area of cylinder= [tex]2\pi rh[/tex]

Considering, π= 3.14

⇒ lateral surface area of cylinder= [tex]2\times 3.14\times 1.5\times 2.5[/tex]

⇒ lateral surface area of cylinder= [tex]23.55 \ m^{2}[/tex]

Area covered by cylindrical roller in one revolution is 23.55 m²

Next finding total number of revolution to cover 16500 m² area.

Total number of revolution= [tex]\frac{16500}{23.55} = 700.6369 \approx 701[/tex]

Hence, Cyindrical roller make 701 revolution to cover 16500 m² area.

Final answer:

The number of revolutions a cylindrical roller makes can be determined by first finding the area it covers in one revolution (using the formula for the surface area of a cylinder) and then dividing the total area covered by this. The formula to calculate the surface area of a cylinder is 2πrh, where r is the radius and h is the length of the cylinder.

Explanation:

First, we need to find the surface area of the roller. The surface area of a cylinder can be calculated using the formula: 2πrh, where r is the radius and h is the height (or in this case, the length of the roller). Here, r = 1.5m and h = 2.5m, so the surface area that the roller covers in one revolution is 2π(1.5m)(2.5m) = 11.25π m².

The roller covers an area of 16500 m², so to find out how many revolutions it makes, we divide the total area by the area covered in one revolution. That is, 16500m² / 11.25π m². After carrying out the division, we get the number of revolutions the roller makes. This will give us the desired answer.

3a-b=-9 -3a-2b=0 solve by elimination

Answers

a = –2 and b = 3

Solution:

Given equations are

3a – b = –9 – – – – (1)

–3a – 2b = 0  – – – – (2)

To solve these equations by elimination method.

Elimination method means eliminating one variable to find the other variable.

Add equation (1) with equation (2), we get

3a – b + (–3a – 2b) = –9 + 0

⇒ 3a – b – 3a – 2b = –9

Combine like terms together.

⇒ 3a – 3a – b – 2b = –9

⇒ 0 – 3b = –9

⇒ – 3b = –9

Divide by (–3) on both sides, we get

b = 3

Substitute b = 3 in equation (1), we get

(1) ⇒ 3a – b = –9

⇒ 3a – 3 = –9

Add 3 on both sides of the equation,

⇒ 3a = –6

Divide 3 on both sides of the equation

a = –2

Hence, a = –2 and b = 3.

Craig types 20 words per minute. Write an expression for the number of words Craig types in m minutes

Answers

Final answer:

The expression for the number of words Craig types in m minutes is 20 words/minute × m minutes. This equation can be used to calculate how many words Craig can type in any given number of minutes.

Explanation:

If Craig types at a speed of 20 words per minute, to find the expression for the number of words he types in m minutes, you would use the simple formula of rate times time. The rate is the number of words per minute, and the time is how many minutes he is typing. Therefore, the expression would be:

20 words/minute × m minutes = number of words Craig can type in m minutes.

To find out if Craig can type more than 200 words, you can set m to a value greater than 10, since 20 words/minute for 10 minutes would result in 200 words exactly (20 × 10 = 200).

find equation of a line through 5 -3 that is parallel to y=1/2x+3

Answers

Answer:

The equation of a line through (5 -3) that is parallel to y = 1/2 x+3 is

y = - 2 x  + 7

Step-by-step explanation:

Let us assume the slope of the line whose equation we need to find is m 1.

The line parallel to the needed line  is:   y=1/2x+3

Comparing it with the general form: y = m x + C

we get m 2 = 1/2

Now, as Line 1 is Perpendicular to Line 2.

m 1 x m 2  = -1

⇒ m 1 x ( 1/2)  = -1

⇒ m 1  = - 2

Also, the point son the line 1 is given as: (x,y)  = (5,-3)

Put the value of point and Slope in y = m x + C to find the value of Y- INTERCEPT.

we get: -3 = (-2) (5) +  C

or, C = -3 + 10 = 7

⇒ C = 7

The general line equation is given as:  y = m x + C

Substituting  the values of C and m, we get:

y = - 2 x  + 7

Hence, the equation of a line through 5 -3 that is parallel to y = 1/2 x+3 is

y = - 2 x  + 7

Number of hot dogs sold:

Answers

Answer:

number of sodas sold = 105

number of hot dogs sold = 61

Step-by-step explanation:

i) Let the number of sodas sold be = x

ii) Let the number of hot dogs sold be = y

iii) It is given that the total number of hot dogs and sodas sold = 166

Therefore we can say that x + y = 166

iv) It also given that the number of sodas sold was 44 more than the number of hot dogs sold

Therefore we can say that x = y + 44

v) Substituting the value of x from iv) in the equation in iii) we get

    (y + 44) + y  = 166 ⇒    2y + 44 = 166    ⇒   2y = 122  ∴ y = 61

   Therefore the number of hot dogs sold = 61

vi) Substituting the value of y from v) in iv) we get

            x = y + 44    ⇒    x = 61 + 44   ∴ x = 105

     Therefore the number of sodas sold = 105

0.6428 = x/12
0.6428 = 12/x

Answers

Answer: 0.766 = x/12

Final answer:

The correct equation for the triangle is determined by the context provided, which may involve setting up proportions or using trigonometric ratios such as the tangent. Without specific information from a diagram or narrative of the triangle, the correct equation cannot be identified.

Explanation:

The correct equation based on the triangle shown is determined by setting up a mathematical relationship (proportion or equation) that represents the situation described in the diagram or narrative associated with the triangle. Without the specific diagram or narrative details, it is impossible to determine the correct equation. However, generally, if you are given the lengths of sides in different units (for example, feet and inches), you would set up a proportion like

1 foot/12 inches = x feet/y inches

and then cross-multiply to solve for x or y.

If you are dealing with trigonometric functions and are given an angle, you may use a function like sine, cosine, or tangent to find a relationship between the sides. The correct equation could include the tangent ratio if the triangle is right-angled and you have the lengths of the opposite and adjacent sides to the given angle:

tan(theta) = opposite/adjacent

Matt wants to build a rectangular enclosure for this animal. One wide of the pen will against the barn. So he needs no fence on that side. The other three sides will be enclosure with wire fencing. If Matt has 1000 feet of fencing. You can find the dimensions that maximizes the area of the enclosure.

Answers

Answer:

A   =  90,312.5 square feet is the maximum area.

Step-by-step explanation:

Here, the shape of the enclosure  = Rectangle

Now, 3 sides of the rectangle needs to be fenced.

Total length of the fencing wire  = 1000 ft

Let us assume the length of the enclosure = L

The width of the enclose = W

According to question:

The length to fenced = Perimeter of the rectangle - 1 side of Enclosure

⇒ 1000  =  2 (L + W) - L

or, 1000 = L +  2 W

or, L  = 1000 - 2 W  .... (1)

Now, as we need to MAXIMIZE the area of the enclosure:

Area of the enclosure  = L x W    =  (1000 - 2 W) x  W

Now simplifying the area expression, we get:

[tex]A(w) = 1000 w - 2w^2[/tex]

This is a parabola that opens downward so there is a maximum point.

The vertex of the parabola is (h,k) where h is the "maximizing number" and k is the maximum area.

Use the fact that h   =   -b/2 a

h   =    -850/(2*[-2])

h  =   -850/(-4)

h   =   212.5 would be the length of all four sides if it were not for the barn

Therefore you have an extra 212.5 feet

Add the 212.5 feet to the opposite side(length) to get 425 feet.

You have a rectangle that is 212.5 feet by 425 feet by 212.5 feet by "the barn".

The width is 212.5 feet which maximizes the area.

A  =   l w

A  =  425*212.5

A   =  90,312.5 square feet is the maximum area.

If the first two terms of a geometric sequence are 4 and 12, which of the following would be the 10th term?


A) 76
B) 84
C) 78,732
D) 236,196

Answers

Answer:

78,732

Step-by-step explanation:

a_1 = 4

a_2 = 12

a_2/a_1 = 12/4 = 3

a_1 = 4

a_2 = 4 * 3 = 4 * 3^1 = 12

a_3 = 4 * 3 * 3 = 4 * 3^2 = 36

a_n = 4 * 3^(n - 1)

For n = 10:

a_10 = 4 * 3^(10 - 1) = 4 * 3^9 = 4 * 19,683 = 78,732

Final answer:

The formula for the nth term of a geometric sequence is a(n) = [tex]\[ a_n = a_1 \times r^{(n-1)} \][/tex], where a(n) is the nth term, a(1) is the first term, and r is the common ratio. In this case, the first term is 4 and the second term is 12. By using the formula, the calculated tenth term is 78,732. Therefore, the correct answer is C.

Explanation:

The formula for the nth term of a geometric sequence is given by:

[tex]\[ a_n = a_1 \times r^{(n-1)} \][/tex]

where:

- [tex]\( a_n \)[/tex] is the nth term,

- [tex]\( a_1 \)[/tex] is the first term,

- [tex]\( r \)[/tex] is the common ratio,

- [tex]\( n \)[/tex] is the term number.

In this case, the first two terms are given as 4 (which is [tex]\( a_1 \)[/tex]) and 12 (which is [tex]\( a_2 \)[/tex]).

The common ratio ([tex]\( r \)[/tex]) can be found by dividing the second term by the first term:

[tex]\[ r = \frac{a_2}{a_1} = \frac{12}{4} = 3 \][/tex]

Now, you can use this common ratio in the formula to find the 10th term [tex](\( a_{10} \))[/tex]):

[tex]\[ a_{10} = 4 \times 3^{(10-1)} \][/tex]

[tex]\[ a_{10} = 4 \times 3^9 \][/tex]

[tex]\[ a_{10} = 4 \times 19683 \][/tex]

[tex]\[ a_{10} = 78,732 \][/tex]

So, the correct answer is: C) 78,732

[tex]CB = \sqrt{(6 - 1.5)^2 + (3 - 0.75)^2}[/tex]

Substituting the values

[tex]CB = \sqrt{(4.5)^2 + (2.25)^2}[/tex]

[tex]CB = \sqrt{(20.25) + (5.0625)}[/tex]

[tex]CB = \sqrt{25.3125}[/tex]

CB = 5.03

The Ratio is   1.677 to  5.03

A painter can paint 350 square feet in 1.25 hours. What is the painting rate in square feet per hour?

Answers

We are given a painter can paint 350 square feet in 1.25 hours.

We want to figure out the painting rate in square feet per hour. “Per hour” means for every 1 hour.

To find this, an equation like 350 = 1.25h (h for hours) can be set up. To solve, the only thing we need to do is divide by 1.25 to get h alone:

350/1.25 = 1.25h/1.25 or 280 = h

The painter can paint 280 square feet per 1 hour.

Solve 0.25[2.5x + 1.5(x – 4)] = –x.

Answers

Answer:

X = 0.75

Step-by-step explanation:

0.25[2.5x + 1.5(X-4)]= -X

0.25[2.5x + 1.5x - 6] = -x

0.25[4x -6] = -x

1x + x = 1.5

2x = 1.5

x = 1.5/2

x = 0.75
