Answer:

4:5

Step-by-step explanation:

A pair of complementary add up to 90, given that one of them is 50, we can do this: x + 50 = 90

solve it and we get x = 40

40 + 50 = 90, so 40 and 50 are the pair of complementary angles.

As for it's Ratio, we can just get the pair and have it as 40:50 but we can reduce it to 4:5

Mr. Ramirez built a wooden storage shed for his tools. The dimensions of the shed are shown below. What is the volume of the sto

ankoles [38]

Answer:

$Volume = 24\ ft^3$

Step-by-step explanation:

Given [Missing from the question]

$Length = 170cm\\ Width = 100cm\\ Height = 40cm$

Required

Determine the volume

This is calculated as:

$Volume = Length * Width * Height$

$Volume = 170cm * 100cm * 40cm$

$Volume = 680000cm^3$

Convert to cubic foot [Divide by 28317 ]

$Volume = \frac{680000\ ft/^3}{28317}$

$Volume = 24.0138432744\ ft^3$

$Volume = 24\ ft^3$ --- approximated

Shawna, Dexter, and Tilana are solving the equation Negative 2. 5 (5 minus n) 2 = 15. Shawna says, "I can begin by dividing each

aleksandrvk [35]

Shawana, Dexter, and Tilana are correct.

<h2>Given that</h2>

Equation: $\rm -2.5(5 - n) + 2 = 15


$

<h3>We have to determine</h3>

Which students are correct?

<h3>According to the question</h3><h3>Equation: $\rm -2.5(5 - n) + 2 = 15


$ </h3>

The correct way to solve the equation is;

SHAWNA

Statement: Dividing each side of the equation by –2.5,

$\rm \dfrac{-2.5(5 - n) + 2 }{-2.5}= \dfrac{15}{-2.5}\\
\\
(5-n) - \dfrac{2}{2.5} = \dfrac{15}{-2.5}\\\\
\\
$

Here, Shawna is correct.

DEXTER

Statement: Distributing -2.5 to get -12.5 + 2.5 n + 2 = 15.

$\rm -2.5(5-n) +2=15\\
\\
-2.5(5) - 2.5 (-n) +2= 15\\
\\
-12.5 +2.5n +2=15$

Hence, Dexter is correct.

" Tirana says, "I can begin by multiplying each side of the equation by Negative Start fraction 1 over 2. 5 End fraction to get 5 minus n minus 0. 8 = negative 6. "

$\rm \dfrac{-1}{2.5} (-2.5 (5-n)+2)= \dfrac{-1}{2.5}\times 15\\
\\
(5-n) + \dfrac{-2}{2.5} = \dfrac{-15}{2.25}\\
\\
(5-n) -\dfrac{2}{2.5} = \dfrac{-15}{2.5}\\
\\
5-n-0.8=-6$

Hence, Tilana is also correct.

Hence, Shawana, Dexter and Tilana are correct.

(2t-3)^3, can you help me?, please?

grandymaker [24]

Answer:

8t^3-36t^2+54t-27

Step-by-step explanation:

(2t-3)^3

(2t-3)(2t-3)(2t-3)

Multiply the first two terms

(4t^2 -6t -6t+9)(2t-3)

Combine like terms

( 4t^2 -12t +9) ( 2t-3)

Multiply

2t*( 4t^2 -12t +9) -3 ( 4t^2 -12t +9)

Distribute

8t^3 -24t^2 +18t-12t^2 +36t-27

Combine like terms

8t^3-36t^2+54t-27
