Answer:

I want to show you how to do this as well, the formula you are working with is a^2+b^2=c^2

Step-by-step explanation:

1.) 8^2+b^2=12^2

64+b^2=144

subtract 64 from both sides

b^2=80

take the square root of 80 and you get

b= 8.9

if you need more help on this let me know, I am going to list the other answers now because to do it all and show work on here is a lot of typing, all of which I will do if you do not understand the first example. Also the c value can ONLY BE THE HYPOTENUSE VALUE. The hypotenuse is the longest side of the triangle. For example, 12 would be the C value on number one and in number two it would be 15.

2.) 14.5

3.) 10.3

4.) 18.8

5.) 8

6.) 15

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

anastassius [24]

Ah, direct variation/proportion.
That is simply a linear equation with a y-intercept of 0.
So... let's solve this.
Simply put, a direct variation multiplies the x-value by a constant to get the y-value.
Let's take the point $(2, 48)$ on this graph and solve for the constant of proportionality:
$2a=48$
We easily solve that and get our answer of $a=24$ . (B)
