Shtirlitz [24]

Answer:

a right triangle

is equal to

Step-by-step explanation:

Pythagorean's theorem is a²+b²=c² with c being the longest sides. If it is true then it is a right triangle.

<u>18²</u> + <u>24²</u> = <u>30²</u>

324+576=900

This is true so the triangle is a right triangle

There are many cylinders for which the height and radius are the same value. Let
VashaNatasha [74]

Answer:

Relation between V and c is represented as:

V = \pi c^{3}

When c is halved, V becomes \frac{1}{8} of its initial value.

Step-by-step explanation:

Height of cylinder = Radius of cylinder = c

Volume of cylinder = V

As per formula:

V = \pi r^{2} h

Where r is the radius of cylinder and

h is the height of cylinder

Putting r = h =c

V = \pi c^{2} \times c\\\Rightarrow V = \pi c^{3} ......(1)

The values of c is halved:

Using equation (1), New volume:

V' = \pi (\dfrac{c}{2})^3\\\Rightarrow \dfrac{1}{8} \pi c^{3}

By equation (1), putting \pi \times c^{3}  = V

V' = \dfrac{1}{8} \times V

So, when c is halved, V becomes \frac{1}{8} of its initial value.

How to solve 10 (g+5)=2(g+9)
Ghella [55]

first multiply the outside numbers by both the numbers in the ()

10xg=10g       10x5=50    2xg=2g             2x9=18

then combine like terms

10g+50=2g+18

8g=32

then divide

g=4

Chantelle has 23 cookies. She gives 3 3/6 to her friend Emily how many does she have now
malfutka [58]
3 3/6 is the same as 3 1/2, so 23 take 3 is 20. 20 take 1/2 is 19 1/2.
