False

Step-by-step explanation:

It is called a hypotenuse it is always the longest side and always cross from the right angle, the other 2 sides are called legs. :)

Two angles form a linear pair. One angle measures (10x - 63). The other angle measures (8x)". What is the value of the larger

EleoNora [17]

Answer:

108 degrees

Step-by-step explanation:

Given

Let the angles be A and B

$A = 10x - 63$

$B = 8x$

Required

Find the larger angle

If both angles form linear pair, then the following relationship exist:

$A + B = 180$

Substitute values for A and B

$10x - 63 + 8x = 180$

Collect Like Terms

$10x + 8x = 180 + 63$

$18x = 243$

Solve for x

$x = \frac{243}{18}$

$x = 13.5$

Substitute 13.5 for x in

$A = 10x - 63$

$B = 8x$

$A= 10 * 13.5 - 63$

$A= 135 - 63$

$A= 72$

$B = 8 * 13.5$

$B = 108$

<em>Hence, the larger angle measures 108</em>

A snack box contains at most 7 ounces of cheese. Fiona says the amount of cheese can be represented by 2x - 3. Which graph shows

Softa [21]

The function representing the number of ounces is:
2x - 3
Now, we are given the number of ounces = 7
Therefore:
2x - 3 = 7
We will solve this equation for x as follows:
2x-3 = 7
2x = 7 + 3
2x = 10
x = 5

Therefore, the number line representing this function will be the line having a solution ending at 5 (5 is included).

Therefore, the correct choice would be line B

A sculpture is in the shape of a square pyramid. The sculpture has a height of 36 feet and a volume of 19,200 cubic feet. Find t

lorasvet [3.4K]

$Hello$ $Human!$

$The$ $answer$ $to$ $this$ $is$ :

$a = 40$ feet

<h2><u>EXPLANATION:</u></h2><h2><u></u></h2>

<u></u>

Given:

V = 19,200 feet³ volume of the sculpture

H = 36 feet height of the sculpture

a = ? side length of the square base

The formula for calculating the volume of a pyramid is:

V = B H / 3 ⇒ B = 3 V / H

B = 3 · 19,200 / 36 = 19,200 / 12 = 1,600

B = a²

a² = 1,600 ⇒ a = √1,600 = 40 feet

a = 40 feet

Solving systems of equations using substitution/elimination
Solving systems of equations by graphing

Step-by-step explanation:

<u>Step 1: Define systems</u>

y = x + 9x + 5

y = -x + 11x + 29

<u>Step 2: Simplify systems</u>

y = 10x + 5

y = 10x + 29

<u>Step 3: Solve for </u><em><u>x</u></em>

<em>Substitution</em>

Substitute in <em>y</em>: 10x + 5 = 10x + 29
Subtract 10x on both sides: 5 ≠ 29

Here we see that 5 does not equal 29.

∴ The systems has no solutions.

<u>Step 4: Graph systems</u>

<em>Check the solution set (if applicable).</em>

We see that the 2 lines are parallel and will never intersect. Therefore, this proves that our systems has no solution.

How do you simplify these problems ?

$\bf ~~~~~~~~~~~~\textit{negative exponents}\\\\a^{-n} \implies \cfrac{1}{a^n}\qquad \qquad\cfrac{1}{a^n}\implies a^{-n}\qquad \qquad a^n\implies \cfrac{1}{a^{-n}}\\\\[-0.35em]\rule{34em}{0.25pt}\\\\\cfrac{2x^3y^3}{4y^2}\implies \cfrac{2}{4}\cdot \cfrac{x^3y^3}{y^2}\implies \cfrac{1}{2}\cdot x^3y^3y^{-2}\implies \cfrac{1}{2}\cdot x^3y^{3-2}\implies \cfrac{x^3y}{2}\\\\~\dotfill\\\\$
