Can you help me? Answer the question please

Harlamova29_29 [7]

Hey there! :D

1. c - 7 = 32

To solve this problem, add the difference and the subtrahend of the given equation.

$32 + 7 = \boxed{\sf 39}$

Checking:

To check, simply substitute the conclusion on the unknown quantity.

39 (c) - 7 = 32

Thus, the equation was correct which gives us the answer that:

$\large \boxed{ \sf {\: c = 39}}$

$\begin{gathered} \\ \end{gathered}$

2. r + 4 = 39

To solve this problem, subtract the sum and the addend of the given equation.

$39 - 4 = \boxed{\sf 35}$

Checking:

To check, simply substitute the conclusion on the unknown quantity.

35 (r) + 4 = 39

Thus, the equation was correct which gives us the answer that:

$\large\boxed{ \sf {r \: = \: 35}}$

If the expression y2 – 16y + 64 is factored completely, which is one of its factors?

kari74 [83]

Answer:

b) y - 8 is one of the factor of the given expression

Step-by-step explanation:

Explanation:-

Given expression y² - 16 y + 64

⇒ y² - 8 y - 8 y + 64

⇒ y ( y- 8) - 8 ( y - 8)

⇒ (y-8)(y-8)

Therefore (y -8) is one of the factor

The height and radius of a cone are each multiplied by 3. What effect does this have

Black_prince [1.1K]

The volume of the original cone is multiplied by 27

<h3>Solution:</h3>

We have been given that the height and radius of a cone are each multiplied by 3.

We need to find what effect it has on the volume of the cone.

The volume of the original cone is given as follows:

$\text {Volume of cone}=\frac{1}{3} \pi r^{2} h$

Now, the radius and height are multiplied by 3.

Therefore, the new radius is ‘3r’ and the new height is ‘3h’.

Hence the new volume is

$\text {Volume of new cone}=\frac{1}{3} \pi(3 r)^{2}(3 h)=9 \pi r^{2} h$

original volume of cone x 27 = volume of new cone

Therefore, the original volume of cone is multiplied by 27
