Answer:
Which real-world situation involves division with a negative number?
splitting a $22.5 million company debt evenly among 2.4 million shareholders
converting 29.21 centimeters to inches by dividing by 2.54
calculating how much a 6.3 inch plant grew each day, on average
calculating the price of one pound of bananas if 3.9 pounds costs $2.34
Step-by-step explanation:
For any sort of pyramid or cone, the volume is 1/3 of the volume of a prism with the same base and height. Since the volume of a prism/cylinder is

, the volume of a pyramid/cone is

.
In this case, our base is a circle, which has a radius of 4 cm.
The area of a circle is

where r is the radius.

We now know that our base is 16π cm.
We also know that our height is 9 cm.
Let's plug these into our volume formula.

Use 3.14 to approximate pi as the question states. 16 × 3.14 = 50.24.

We could punch all of that into our calculator to get the same answer, but since 1/3 of 9 is clearly 3, let's just go with that.

Answer:
(-5,-1)
Step-by-step explanation:
2x+y=9 -> y=-2x+9
3x-y=16
3x-(-2x+9)=16
3x+2x-9=16
5x-9=16
5x-9 (+9)=16 (+9)
5x=25
x=5
no plug in 5 to x in any equation above
2(5)+y=9
10+y (-10)=9 (-10)
y=-1
so the answer is (-5,-1)
hope it's correct! and hope i helped
Answer:
Length=17
width=13
Step-by-step explanation:
W=width
L=length
Perimeter = 2w+2l since it's a rectangle
W=l-4 (given)
Plug into perimeter equation
Perimeter =(2l-8)+2l
=4l-8
60=4l-8
68=4l
17 =l
W=l-4=17-4=13
