Answer:

The height of the tower = 24 units.

Explanation:

In the question above, we are given the following variables.

The total number of blocks used = 312 blocks

The bottom layer( base of the tower) = 13 blocks

We are to find how tall the tower is = height of the tower = unknown.

The total number of blocks used = Volume of the tower = 312 cubic units(blocks)

Area of the base = number of the blocks used in the bottoms layer = 13 square units( block).

Because blocks are used, we assume that this is a Rectangular based prism

The Volume of a Rectangular based prism = Area of the base × h

312 = 13 × h

h = 312 cubic units ÷ 13 square units.

h = 24 units.

There fore, the height of the tower = 24 units

Find the value of each variable. Write an equation then solve showing ALL the work A2x+10°

AveGali [126]

Answer:

x = 25

Step-by-step explanation:

The three straight lines in the sides of the triangle means that ALL 3 SIDES ARE EQUAL.

This is an equilateral triangle. So all 3 angles are equal.

We know sum of 3 angles in a triangle is 180. Since 3 of the angles are equal, each angle is:

180/3 = 60

The top angle is given as "2x + 10", thus we can say "2x + 10" is equal to 60 degrees. Now we equate and solve for x:

$2x+10=60\\2x=60-10\\2x=50\\x=\frac{50}{2}\\x=25$

The value of x is 25

Which expressions are equivalent to Negative 9 (two-thirds x + 1)? Check all that apply.

Sav [38]

Answer:

$-9(\frac{2}{3}x) + 9(1)\\ \\-6x + 9$

Explanation:

Before we begin, remember the following rules:

1- Distribution property:

$a(b+c) = ab+ac$

2- Simplification of fractions:

$\frac{xy}{yz}=\frac{x}{z}$

3- Signs in multiplication:

+ve * +ve = +ve

-ve * -ve = +ve

+ve * -ve = -ve

Now, for the given problem, we have:

$9 (\frac{2}{3}x + 1)$

Starting with the distributive property:

$-9 (\frac{2}{3}x +1) = -9(\frac{2}{3}x) - (-9)(1) = -9(\frac{2}{3}x) + 9(1)$

..................>This corresponds to option 1

Now, we simplify the output from the above step:

$-9(\frac{2}{3}x) + 9 = \frac{-9*2}{3}x + 9 = -6x+9$

................> This corresponds to option 5

Hope this helps :)
