A group of friends is roping off a soccer field in a back yard. A particular full-size soccer field is a rectangle with a length of 100 yards and a width of 50 yards. To fit the field in the back yard, the group needs to reduce the size of the field so its perimeter is 60 yards.
What is the Area of the soccer field in the back yard?

Answers

Answer:

200 ft

The original perimeter would be 300, so divided by 5, it would be 60. 100/5 is 20, 50/5 is 10. 20*10 is 200.

Two angle measurements of a triangle are 62° and 28°. What is the measurement of the third angle?

Here are your options!
90°, 110°, 10°, 62°

Answers

Answer:

90°

Step-by-step explanation:

the sum of the angle measurements of a triangle always equals 180°

so if you add the 2 you have you would get 90°

then you subtract that from 180°

x= 180°- (62°+ 28°)

Answer:

the third angle would measure 90 degrees

Step-by-step explanation:

the answer is 90 degrees because 62+28=90 and the area of a triangle is 180 degrees so 180-90=90

Answers

Answer:

The independent variable belongs on the x-axis (horizontal line) of the graph and the dependent variable belongs on the y-axis (vertical line). The x and y axes cross at a point referred to as the origin, where the coordinates are (0,0).

A linear relationship is a relationship with a constant rate of change represented by a graph that forms a straight line that passes through the origin (0, 0) and is represented by y = kx. The rate of change is either positive, negative, zero, or undefined.

-3/-3=1

y=1x+c

c= y-intercept and (0,2) is the y-intercept so

y=1x+2

I think

Y=1x+2
Because 1 is the slope and 2 is the y intercept
