Last question of a really important test! I really need some help!
A hollow ball is made of rubber that is 1 centimeter thick. The ball has a radius of 5 centimeters at the outside surface.
What is the approximate volume of rubber used to make the ball?
Use 3.14 for pi.
255.4 cm³
If you would like to know the value of the larger number, you can calculate this using the following steps:
2 ... 3
18 ... x = ?
2 * x = 3 * 18 /2
x = 3 * 18 / 2
x = 27
The correct result would be 27.
Question: The area of triangle MNP is how many times the area of triangle JKL?
Answer: The answer you want would be 9... The area of triangle MNP is 9 times larger than the area of triangle JKL.
Explanation: It would be 9 times larger because it says the base and height which means multiply the base and the height so it would be 3*3=9
Hope It Helps!!
Answer: x=1.6
y=4.2
Step-by-step explanation:
5.2x - y = 4.1
1.5x + y = 6.7
we will add both equations and you see that the y is getting cancelled
6.7x=10.8
x=10.8/6.7= 1.6
now in any equation we will replace x with 1.6
5.2(1.6)-y=4.1
8.3-y=4.1
-y= 4.1-8.3
-y=-4.2 multiply by -1
y=4.2
=
Multiply both sides by 15
6 =
Multiply both sides by c
6c = 30 Divide both sides by 6
c = 5
