Help pls<br><br>52 is 65% of what? <br><br>45% of 40 is what number? ​
Masja [62]

Let, that number = x

It would be: x * 0.65 = 52

x = 52 / 0.65

x = 80

So, that number and your answer is 80

18 is 45% of 40

45%/100 = 0.45

0.45*40=18

Find x. Round your answer to the nearest tenth of a degree . Please help I will mark brainliest
Oksana_A [137]

Using trigonometric ratio, the value of x is 63.6°

<h3>Trigonometric Ratio</h3>

This is the ratios of sides of a right-angled triangle with respect to any of its acute angles are known as the trigonometric ratios of that particular angle.

Trigonometric ratio are often coined as SOHCAHTOA

In the given triangle, we need to find the value of x using trigonomtric ratio.

Since we have the value of adjacent and hypothenuse, we definitely need to use cosine

cosθ = adjacent / hypothenuse

adjacent = 4

hypothenuse = 9

Substituting the values into the equation;

cos θ = 4 / 9

cos θ = 0.444

θ = cos⁻¹ 0.4444

θ = 63.6°

kifflom [539]

Answer:

792\ \text{pounds}

Step-by-step explanation:

x_1=70 cubic feet of fertilizer is used in y_1=770 pounds of strawberries

x_2=90 cubic feet of fertilizer is used in y_2=990 pounds of strawberries

x=72 cubic feet of fertilizer is used

Linear interpolation is applied

y=y_1+\dfrac{(x-x_1)(y_2-y_1)}{x_2-x_1}\\\Rightarrow y=770+\dfrac{(72-70)(990-770)}{90-70}\\\Rightarrow y=792\ \text{pounds}

72 cubic feet of fertilizer will yield 792\ \text{pounds} of strawberries.
