Step-by-step explanation:

c^2 = a^2 + b^2

$\sqrt{40 ^{2} + 30 {}^{2} } = 50$

$\sqrt{60 {}^{2} - 40 {}^{2} } = 44.7$

Vladimir79 [104]

Answer:

The required equations which represents the relationship between x and y is $0.2(x+y)=0.4x+0.1y$ .

Step-by-step explanation:

Consider the provided information.

Dalia makes a cranberry apple punch that contains 20%, percent real juice by mixing x gallons of a cranberry drink with y gallons of an apple drink.

This can be written as: $\frac{20}{100}(x+y)$

The cranberry drink contains 40 percent real juice and the apple drink contains 10 percent real juice.

This can be written as: $\frac{40}{100}x+\frac{10}{100}y$

Now both the equation are equal.

$\frac{20}{100}(x+y)=\frac{40}{100}x+\frac{10}{100}y$

$0.2(x+y)=0.4x+0.1y$

Hence, the required equations which represents the relationship between x and y is $0.2(x+y)=0.4x+0.1y$ .

The sound intensity of rustling leaves is 100 times the reference intensity. Use your graph to determine the sound intensity of

wariber [46]

The sound intensity of rustling leaves, y = 20 decibels

<u>Step-by-step explanation:</u>

y = 10logx

The sound intensity of rustling leaves is 100 times the reference intensity.

x = ratio of intensity of sound to reference to intensity

x = 100:1 or x = 100

y = 10 log(100) = 10 * 2 = 20 decibels

y = 20 decibels

Remember, the slope formula is y2-y1 over x2-x1. To plug numbers into the formula, find two points. Then, you substitute the points into the formula.
