Trevor drew a scale drawing of a neighborhood park. the scale he used was 1 inch : 3 yards. a soccer field in the park is 90 yards long in real life. how long is the field in the drawing?

30 inches

Step-by-step explanation:

1 inch : 3 yards means

1 inch in paper (drawing) is 3 yards in actual life

We can setup a simple ratio and solve this problem.

1 inch is 3 yards, so how many inch is 90 yards?

This is the question.

We set up 2 fractions  (one for ratio and another for actual) and equate, cross multiply and solve:

The left side fraction would be the ratio, that is:

1/3

THe right side fraction would be the actual, that is:

x inches (let it be x, we want to find x)

90 yards

SO we can write and solve:

Hence,

The field is 30 inches in the drawing

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

it is not that hard all u have to do is plot the graph
