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&#10;&#10;&#10;

<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&#10;&#10;&#10;</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}\\&#10;\\&#10;(5-n) - \dfrac{2}{2.5} =  \dfrac{15}{-2.5}\\\\&#10;\\&#10;

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\\&#10;\\&#10;-2.5(5) - 2.5 (-n) +2= 15\\&#10;\\&#10;-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\\&#10;\\&#10;(5-n) + \dfrac{-2}{2.5} = \dfrac{-15}{2.25}\\&#10;\\&#10;(5-n) -\dfrac{2}{2.5} = \dfrac{-15}{2.5}\\&#10;\\&#10;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
