Answer:

3x²+x-5

Step-by-step explanation:

= 3(xx)+x-5

According to the rule, when bases are same powers are to be added.

What is the volume of a volleyball with a diameter of 8 inches
natita [175]

Hello there!

We are going to follow the volume of a sphere since a volleyball is a sphere. V=4/3πr^3 is the formula for finding the volume of a sphere. The only unknown value is r, or the radius. We find the radius by halving the diameter.

8/2 = 4, so we have a radius of 4 inches.

Place the value of 4 in for r - V = 4/3 x π x (4)^3

Now solve.

V = 4/3 x π x (4)^3

Start by squaring 4.

V = 4/3 x π x 64

Next, multiply 4/3 by 64. (<em>you can do it in any order since there are no parenthesis</em>)

V = π x 85.33

Lastly, multiply 85.33 by pi.

V = 268.08

So, your answer is approximately 268.08, since we used rounding it is not exact. I hope this was helpful and have a great rest of your day! :)

Question-

To build a door frame, Anthony needs 2 pieces of lumber that each measure 98 1/4 inches and one piece of lumber that measure 39 1/2 inches. What is the total length of lumber that Anthony needs to build the frame?

Answer:

137 3/4 inches

Step-by-step explanation:

98 1/4 + 39 1/2

First, find the LCD (4)

98 1/4 + 39 2/4

98 + 39 = 137

1/4 + 2/4 = 3/4

PLEASEEEE HELPPPPP MEEEEEE!!!!<br> Find h in the diagrams below.
Leno4ka [110]

Answer:

  • 9.6
  • 11.2

Step-by-step explanation:

It is useful to label the diagram so we can talk about the parts. (See the attachment.)

AB and CD are parallel lines, crossed by transversal AE. So, angles FAE and CDE are congruent. These are acute angles in a right triangle, so the triangles AFD and DEC are similar by the AA postulate.

This similarity means that corresponding sides are proportional:

  CE/CD = DF/DA

  CE = CD(DF/DA) = 16(6/10) = h

  h = 9.6

__

The second problem is identical to the first, but with different numbers.

  CE = CD(DF/DA) = 14(8/10) = h

  h = 11.2
