Well a triangle equals 180 degrees so if you already have 90 then you would need the other 90. By looking at the triangle I would say y=45. I hope I helped! :)

The picture is cut off so if they are asking you to round to the nearest tenth the answer is 50, if not it is 45

Answer : 50

So the total degrees of a triangle are 180

you know that one of the angles has 90

so do 180 - 90 = 90

so now do 90 in half, so 45

45 rounded to the nearest 10th is 50

Hope this Helped :)

ANSWER : 9 over 4

or 2 and 1/4

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

*3 over 2 x 3 over 2 is 3/2 x 3/2* << this is for me to remember

Okay so multiplying fractions means for us to multiply across. That means if we line the fractions, we multiply. Like this

3 x 3

----- ----- 3 times 3 is = 9

2 x 2 2 times 2 is = 4

9 over 4 is the same thing as 2 and 1/4 << FRACTION

A camp counselor starts from home and drives to a campground. The expression 130−60t represents the distance, in miles, the coun

telo118 [61]

Answer:

<em>The value 60 represents the speed of the vehicle the counselor is driving.</em>

Step-by-step explanation:

<u>Linear Function</u>

The linear relationship between two variables d and t can be written in the form

$d=mt+b$

Where m is the slope (or rate of change of d with respect to t) and b is the y-intercept or the point where the graph of the line crosses the y-axis

The function provided in our problem is

$d=130-60t$

Where d is the distance in miles the counselor still needs to drive after t hours. Rearranging the expression:

$d=-60t+130$

Comparing with the general form of the line we can say m=-60, b=130. The value of -60 is the slope or the rate of change of d with respect to t. Since we are dealing with d as a function of time, that value represents the speed of the vehicle the counselor is driving. It's negative because the distance left to drive decreases as the time increases

The formula P = 4s gives the perimeter P of a square with side length s.

It would be bigger than 1/2 inches because they are simply asking for the difference which is 5 1/2-5= 1/2.
