-7 2/3 +(5 1/2) + 8 3/4 =
Answer:
6 7/12
Step-by-step explanation:
-7 2/3 +(5 1/2) + 8 3/4
Get a common denominator of 12
-7 2/3 * 4/4 +(5 1/2 +6/6) + 8 3/4*3/3
-7 8/12 + 5 6/12 + 8 9/12
Subtract the first two terms first
They have opposite signs so subtract and take the sign of the larger
-7 8/12 + 5 6/12 = -2 2/12
-2 2/12 + 8 9/12
They have opposite signs so subtract and take the sign of the larger
-2 2/12 + 8 9/12 = 6 7/12
Alexander is a stockbroker. He earns 13% commission each week. Last week, he sold $4 comma 500 worth of stocks. How much did he make last week in commission? If he averages that same amount each week, how much did he make in commission in 2011?
Multiply the amount he sold by the percent of commission:
4500 x 0.13 = 585
he made $585 last week.
There are 52 weeks in a year, multiply the amount of commission by 52:
585 x 52 = 30,420
he made $30,420 in 2011.
Alexander made $585 in commission last week. In 2011, he made $30,420 in commission.
Explanation:To calculate Alexander's commission, we can multiply the value of the stocks he sold by the commission rate.
$4,500 imes 0.13 = $585
Therefore, Alexander made $585 in commission last week.
To calculate how much he made in commission in 2011, we need to know the number of weeks in 2011. Assuming there are 52 weeks in a year, we can multiply Alexander's weekly commission by the number of weeks in 2011:
$585 imes 52 = $30,420

Answer:
65 square inches.
Step-by-step explanation:
To solve for this irregular figure, you must break it into separate rectangles.
Firstly, we can solve for the area of the top rectangle by:
6×4= 24 sq in.
For the next rectangle, we can do:
4×8= 32 sq in.
Finally, the remaining square can be solved by:
3×3= 9 sq in.
To get the ENTIRE area, you will need to add these areas up which gets you:
24+ 32+ 9= 65 sq in.

Answer:
26 square feet (no floor)38 square feet (with floor)Step-by-step explanation:
The triangular end of the tent has a base of 3 ft and a height of 2 ft. Its area can be found using the formula for the area of a triangle:
A = (1/2)bh
A = (1/2)(3 ft)(2 ft) = 3 ft^2
__
The rectangular side of the tent has a length of 4 ft and a width of 2.5 ft. Its area can be found using the formula for the area of a rectangle:
A = lw
A = (4 ft)(2.5 ft) = 10 ft^2
___
If we assume the tentmaker makes the two sides not shown exactly the same as these, then the total above-ground material will be ...
2(3 ft^2 +10 ft^2) = 26 ft^2
If there is on-ground material (a floor), that rectangle adds (3 ft)(4 ft) = 12 ft^2 to the total.
The area of the tent above-ground is 26 square feet. With a floor, it is 38 square feet.

Answer:
A
Step-by-step explanation:
Equate the congruent sides of the side, that is
2x + 2 = x + 6 ( subtract x from both sides )
x + 2 = 6 ( subtract 2 from both sides )
x = 4
and
y - 5 = x + 5 = 4 + 5 = 9 ( add 5 to both sides )
y = 14
Thus
top pair = x + 5 = 4 + 5 = 9 and lower pair = x + 6 = 4 + 6 = 10

A line is parallel to y = -2x + 1 and
intersects the point (4,1). What is the
equation of this parallel line?
Answer:
For this case since we want a parallel line to -2x+1 we need the same slope so then m = -2 and we have:
[tex] y =-2 x+b[/tex]
Now we can find the intercept b with the condition given x= 4 , y=1 and we got:
[tex] 1 = -2*4 +b[/tex]
And solving for b we got:
[tex] b = 1+8 = 9[/tex]
And our equation would be:
[tex] y = -2x +9[/tex]
Step-by-step explanation:
For this case we need to find an equation for a line who is parallel to y = -2x + 1 and intersects the point (4,1)
The general equation for a line is given by:
[tex] y = mx +b[/tex]
For this case since we want a parallel line to -2x+1 we need the same slope so then m = -2 and we have:
[tex] y =-2 x+b[/tex]
Now we can find the intercept b with the condition given x= 4 , y=1 and we got:
[tex] 1 = -2*4 +b[/tex]
And solving for b we got:
[tex] b = 1+8 = 9[/tex]

A used car dealer sells SUVs and cars. Of all the vehicles, 90% are cars. Of all the vehicles 40% are red cars. What is the probability that a car chosen at random is red? Round your answer to the nearest tenth of a percent.
Answer:
44.4%
Step-by-step explanation:
To calculate this, we proceed as follows.
we use the probability equation below;
P(A|B) = P(A and B) / P(B)
Applying the above to the scenario at hand;
P(red | car) = P(red and car) / P(car)
P(red and car) = 40% or simply 40/100 = 0.4
P(car) = 90% = 90/100 = 0.9
P(red | car) = 0.4/0.9
P(red | car) = 0.4444 which is = 44.44% ; to the nearest tenth of a percent = 44.4%
To find the probability of a randomly chosen car being red, you divide the percentage of red cars by the percentage of all cars. The calculation results in 44.4%, which is the probability that a car is red.
Explanation:To find the probability that a car chosen at random is red, we use the information provided: 90% of all vehicles are cars, and 40% of all vehicles are red cars. To determine the probability of a randomly selected car being red, we must calculate the percentage of red cars within the group of all cars.
This is done by dividing the percentage of red cars by the percentage of all cars, which gives us the probability that a car, given it's a car, is red.
The calculation is (40% / 90%) × 100, which simplifies to 44.4%. Rounded to the nearest tenth of a percent, the probability is 44.4%.

Answer:
Length = 13
Width = 9
Step-by-step explanation:
The equation to find the perimeter is 2l+2w=44. The second equation is 2w-5=l since the length is 5 less than double the width.
2l+2w=44,2w-5=l (write equations)
use the equation for length, the second equation, and subtitute it into the first equation's l. Since all l is the same and 2w-5 is equal to l, we can use that equation for the l in 2l+2w=p
2(2w-5)+2w=44 (subtitute)
4w-10+2w=44
6w-10=44 (simplify)
6w=54 (add 10 to both sides)
w=9
use the width to find the length by plugging it into any original equation
2w-5=l
2(9)-5=l
18-5=l
13=l
Answer:
The length is 13.
The width is 9.
Step-by-step explanation:
length = x
width = w
1) x = 2w - 5
2) 44 = 2x + 2w
3) 44 = 2(2w - 5) + 2w
4) 44 = 4w - 10 + 2w
5) 44 = 6w - 10
6) 54 = 6w
7) w = 9
8) x = 2(9) - 5
9) x = 18 - 5
10) x = 13

A flagpole is at a (3x + 24)degrees° angle from the ground. Find the value of x.
The value of x is 22. The angle the flagpole makes with the ground, represented as 3x+24∘, is supplementary to the angle the flagpole makes with the vertical line, which is 90 degrees. By setting up the equation 3x+24° + 90° =180°. and solving for x, we find =22. Thus, the flagpole makes a 3(22) + 24° + 90° =180° angle with the ground.
Certainly, let's break it down step by step:
Given: The angle the flagpole makes with the ground is [tex]\(3x + 24^\circ\).[/tex]
1. **Define the problem**: Let [tex]\( \theta \)[/tex] represent the angle the flagpole makes with the ground.
2. **Write the given information**:
[tex]\[ \theta = 3x + 24^\circ \][/tex]
3. **Understand the geometric situation**: The angle formed by the flagpole with the ground is supplementary to the angle formed by the flagpole with the vertical line
4. **Write the equation based on the supplementary angles relationship**:
[tex]\[ \theta + 90^\circ = 180^\circ \][/tex]
5. **Substitute the given value of [tex]\( \theta \)[/tex]**:
[tex]\[ (3x + 24^\circ) + 90^\circ = 180^\circ \][/tex]
6. **Simplify the equation**:
[tex]\[ 3x + 24^\circ + 90^\circ = 180^\circ \][/tex]
7. **Combine like terms**:
[tex]\[ 3x + 114^\circ = 180^\circ \][/tex]
8. **Isolate \(x\)**:
[tex]\[ 3x = 180^\circ - 114^\circ \][/tex]
[tex]\[ 3x = 66^\circ \][/tex]
[tex]\[ x = \frac{66^\circ}{3} \][/tex]
[tex]\[ x = 22 \][/tex]
[tex]So, \( x = 22 \).[/tex]
What is the value of x
Answer:
x=123
Step-by-step explanation:
x is across from the angle that measures 123 degrees. Therefore, they are vertical angles, and are congruent.
x=123
Additionally, 57 and x are on a straight line. This means they are supplementary and add to 180 degrees
57*x=180
Subtract 57 from both sides to get x by itself.
x=123
What’s the solution to #4?
Answer:
95/pie
Step-by-step explanation:
2 × radius = diameter
2 × pie × radius = circumference
2 × pie × radius = 95cm
radius = 95/2 × pie
Diameter = [95/2 × pie] × 2
Diameter = 190/2 × pie
Diameter = 95/pie
(It wasn't stated in the question but if pie = 22/7, the diameter is 95 × 7/22 = 30.23 (approximately)

CYLINDER: πr2h
CONE: πr2h ÷ 3
CYLINDER WORK:
Your radius is 2, which was a simple find! It wants it squared, so simply do 2x2 to get your squared radius of 4. Now that you know this, as well as your height, which is 3, let's plug it in!
π×4×3 (I would suggest putting this in your calculator)
=37.7
CONE WORK:
Your radius is 2 again, which was a simple find because its half your diameter, or 4! It wants it squared again, so simply do 2x2 to get your squared radius of 4. Now that you know this, as well as your height, which is 9, let's plug it in! The only difference is you have to divide your whole answer by three since it's different for a cone.
π×4× 9 ÷ 3 (I would suggest putting this in your calculator)
=37.7
Well, what a coincidence, they are the same! This proves that it does not depend on the height, it will only depend on the proportions of your shape, since the cylinder could have had a much larger scale of numbers, which would make it bigger not based on it's shape, but it's overall size.
The sum of three consecutive numbers is 72. What is the smallest of
these numbers?
x + (x + 1) + (x + 2) = 72
x+ (x + 2) + (x + 4) = 72
3x = 72

Let x be the first number
x+1 is the next consecutive number
x+2 is the next consecutive number
The sum is
x+ x+1 + x+2 = 72
Combine like terms
3x+3 = 72
subtract 3 from each side
3x+3-3 = 72-3
3x = 69
Divide each side by 3
3x/3 = 69/3
x = 23
x+1 = 24
x+2 =25
