Answer:

1728ft³

Step-by-step explanation:

Split the shape into the two rectangular prism that make it up

Volume of a rectangular prism=length*width*height

Small prism=10*12*3=360ft³

Big prism=19*12*6=1368ft³

Total=360ft³+1368ft³=1728ft³

Answer:

It will take them about 5 hours to do the cleaning.

Step-by-step explanation:

Since all three of them are going to do it together, you must find the average amount of time between the three of them. To do this you add all of their cleaning times, 6, 5 and 4, and them divide by the amount of people there. 6+5+4= 15, 15/3=5.

Answer:

200π m²

Step-by-step explanation:

The lateral area (A) of a cone is calculated as

A = πrl ( r is the base radius and l the slant height )

Here r = 8 and l = 25, then

A = π × 8 × 25 = 200π cm²

Given:

In ΔWXY, x = 680 inches, w = 900 inches and ∠W=157°.

To find:

The all possible values of ∠X, to the nearest degree.

Solution:

Law of Sines:

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

For ΔWXY,

[tex]\dfrac{w}{\sin W}=\dfrac{x}{\sin X}=\dfrac{y}{\sin Y}[/tex]

Now,

[tex]\dfrac{w}{\sin W}=\dfrac{x}{\sin X}[/tex]

[tex]\dfrac{900}{\sin (157^\circ)}=\dfrac{680}{\sin X}[/tex]

[tex]900\sin X=680\sin (157^\circ)[/tex]

[tex]\sin X=\dfrac{680}{900}\sin (157^\circ)[/tex]

[tex]\sin X=0.295219[/tex]

[tex]X=\sin^{-1}(0.295219)[/tex]

[tex]X=17.17067[/tex]

[tex]X\approx 17[/tex]

Therefore, the value of ∠X is 17 degrees.

Answer:

Distance travelled by Monarch butterfly = 2000 miles

Distance travelled by desert locust  = 2800

Distance travelled by pink-spotted hawk moth= 7800 miles

Step-by-step explanation:

Let the distance travelled by Monarch butterfly  be "X" miles

Distance travelled by desert locust is equal to X + 800 miles

Distance travelled by pink-spotted hawk moth is equal to 4X -200 miles

The total distance travelled by the three is equal to 12600 miles

[tex]X + X + 800 + 4X -200 = 12600\\6X = 12600 -600\\6X = 12000\\X = 2000[/tex]

Distance travelled by Monarch butterfly = 2000 miles

Distance travelled by desert locust  = 2000 + 800 = 2800

Distance travelled by pink-spotted hawk moth = 4 * 2000 -200 = 7800 miles

Answer:

Step-by-step explanation:

5/7 = 12/y

5y = 84

y = 84/5

Angle (p+7)° and angle (3p+1)° are a linear pair so their sum will be equal to 180°.

Which means :

[tex] =\tt 3p + 1 + p + 7 = 180[/tex]

Let us solve that equation to find the value of p and the two angles :

[tex] =\tt 3p + 1 + p + 7 = 180[/tex]

[tex] =\tt 3p + p + 1 + 7 = 180[/tex]

[tex] =\tt 4p + 8 = 180[/tex]

[tex] = \tt4p = 180 - 8[/tex]

[tex] = \tt4p = 172[/tex]

[tex] =\tt p = \frac{172}{4} [/tex]

[tex]\hookrightarrow \tt \color{plum}p = 43[/tex]

Thus, value of p = 43

Measure of angle (p+7)° :

[tex] =\tt 43 + 7[/tex]

[tex]\tt\color{plum}angle \: (p + 7)° =\tt 50°[/tex]

Measure of angle (3p+1)° :

[tex] =\tt 43 \times 3 + 1[/tex]

[tex] = \tt129 + 1[/tex]

[tex]\tt\color{plum}angle \: (3p + 1)° = 130°[/tex]

Thus, the measure of the larger angle = 130°

Therefore, the correct option is (a) 130

11/30 + 7/30 = 18/30

30/30 - 18/30 = 12/30

12/30 = 0.4

40% liked neither.

Answer:

percent of classmates looked liked neither of 'em=40%

Step-by-step explanation:

students who liked chocolate cake=11

students who liked white cake=7

students who didn't like either of it=30-18=12

percentage of ''=[tex]\frac{12}{30}[/tex] ×100=40%

Answer: Multiply 7.5% by the price after subtracting the coupon's value.

Step-by-step explanation:

Let's assume that the cost of the shirts is x. So the coupon would subtract y from x so that's x-y which gives us z. Then to find z, on a calculator just put in 7.5% x z. I used variables since I don't know the value of the coupon or the original price of the shirts.

Answer:

y= -3/2x + 5

Step-by-step explanation:

You do the opposite reciprocal of the original equation's slope.

Then you use the new slope from the point (4,-1) on the graph to find the y-intercept. Which is (0,5).

That gets your answer of -3/2x + 5.

Step-by-step explanation:

There are 5280 feet in a mile and 3600 seconds in an hour.

So a truck driving 45 miles an hour would be driving:

[tex]\frac{45 miles}{1 hour}[/tex] x [tex]\frac{1 hour}{3600 seconds}[/tex] x [tex]\frac{5280 feet}{1 mile}[/tex] = [tex]\frac{237600}{3600}[/tex] = 66 feet per seconds

Answer:

x = 10

y = 7

Step-by-step explanation:

4x-2 = x+28

4x-x = 28+2

3x = 30

x = 30÷3

x = 10

4y-7 = y+14

4y-y = 14+7

3y = 21

y = 21÷3

y = 7

Answer:

The answer is 12.

Step-by-step explanation:

The sum of two numbers is 17 and their difference is 5. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 17. In other words, x plus y equals 17 and can be written as equation A:

x + y = 17

The difference between x and y is 5. In other words, x minus y equals 5 and can be written as equation B:

x - y = 5

Now solve equation B for x to get the revised equation B:

x - y = 5

x = 5 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 17

5 + y + y = 17

5 + 2y = 17

2y = 12

y = 6

Now we know y is 6. Which means that we can substitute y for 6 in equation A and solve for x:

x + y = 17

x + 6 = 17

X = 11

Summary: The sum of two numbers is 17 and their difference is 5. What are the two numbers? Answer: 11 and 6 as proven here:

Sum: 11 + 6 = 17

Difference: 11 - 6 = 5
