On a trip to Washington D. C., Jose bought a model of the Washington Monument. His model is 8 inches tall. If the scale of the model is 1 inch to 70 feet, what is the actual height of the Washington Monument? 70 feet 560 feet 700 feet 1,200 feet ...

560 feet

Step-by-step explanation:

We are given the scale of the model as:

The scale of the model is 1 inch to 70 feet,

His model is 8 inches tall.

The actual height of the Washington Monument is calculated as;

1 inch = 70 feet

8 inches = x feet

Cross Multiply

x = 8 × 70 feet

x = 560 feet

The actual height of the Washington monument is 560 feet.

options a,b,c are the right answer.

step-by-step explanation:

a linear parent function is always represented as y = x

if we write this function in the form of y=mx+c

⇒

or  

now if we plot a graph we will find these characteristics:

1) y intercept of the graph is zero so its a straight line passing through origin.

2) as we can see in both the forms of function written, values of x and y may be either positive or negative for the positive slope means points on the graph are either in first quadrant or in third one.

3) it's slope is one.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
