Answer:

27

Step-by-step explanation:

on one face you see 3 x 3 (top face)

3 x 3 = 9

and if you look at another side (right one is what im looking at) you will see 3 x 3 again so that means this will be equal to 3 cubed (3^3) or 3 x 3 x 3

if you do 9 x 3

9 x 3 = 27

that equals the volume of the cube

27 units cubed

Answer:

8.625 ft, second option

Step-by-step explanation:

For the rectangles:

1.5 * 2.5 = 3.75

So, 3.75 ft for one rectangle

But there are two rectangles, so:

3.75 * 2 = 7.5

So now the area is 7.5ft for both rectangle.

For the triangle:

Triangle formula - 1/2 × Base × Height

In this case both the base and the height are 1.5 so next step is multiplying by plugging in the numbers

1/2 * 1.5 * 1.5 = 1.125

So the area for the triangle is 1.125 ft

Total area:

Now you just add the numbers you got which is 7.5 and 1.125

7.5 + 1.125 = 8.625

The area is 8.625 ft

The volume of a rectangular prism is V = lwh

l = 20yd

w = 3.25yd

h = 12yd

All we need to do to find the volume is multiply all the number together :

V = 20yd * 3.25yd * 12yd

V = 65yd * 12yd

a. 10.125  inches. 81/8 = 10.125

The answer for a) is 10.125 inch and b) is  2.5 inch, 1.875 inch

What is an inch?

Inch is a unit of linear measure equal to one twelfth of a foot (2.54 cm).

a) According to the question the real time length of the  court is 81 ft

But from the question 1 inch in diagram is equal to 8 ft

So, 81/8=10.125

Thus the entire length of the court if it is 81 ft in real life is 10.125 inch

b) According to the question the real time length and width of receiver A is 20ft and 15ft

So, in diagram it could be in

length is  20/8 = 2.5 inch

width is 15/8 = 1.875 inch

Thus the length and width of receiver A is 2.5 inch, 1.875 inch

A radar measures the speed of a car at 45 miles per hour. The actual speed of the car is 40 miles per hour what is the percent error in the reading of the radar.

Answers

Answer:45

Step-by-step explanation:

answer: 11.11%

step-by-step explanation:
the radar was off by 5 miles per hour, so we need to find what percent 5 is out of 45. percent of (times) if you don’t know how to find that out.
make the assumption that 45 is 100% because it is the output.
next we represent the value we seek with x. so 100% = 45 and x% = 5.
this gives us the simple pair of equations 100% = 45(1) and x% = 5(2).
then multiplying the equations together like 100%/x% = 45/5.
make it into its reciprocal so x%/100% = 5/45. that comes out to be x= 11.11%
5 is 11.11% of 45 so the radar is off by 11.11%

Part B: What is the solution to the pair of equations?

Answers

Answer:

A. You would first plot the y intercept.  The first equation would be (0,-8) and the second equation is (0,-11).  Then you would plot the slope.  For the first equation, from (0,-8), you would move up 3 plots and right 1 plot.  For the second equation, from (0,-11), you would move up 9 plots and right 1 plot.

B. The solution to the pair of inequalities is (1/2, -13/2).  That is the intersection and point of the two lines.  You would need to graph the two lines (see part A answer) and then find the intersection.
