Answer:
45 miles
Step-by-step explanation:
first divide miles/minutes: 15 / 20 = 0.75
then multiply: 0.75 x 60 = 45
This is an EXPONENT.
To do this all we need to do is multiply the base by itself how many times the power says.
(-6)² = (-6) × (-6) = 36
Recall that any negative number times another negative number is positive so that is why this would be positive.
So, (-6)² = 36

The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
Step-by-step explanation:
The given is,
a = 5
b = x - 1
c = x
Step:1
Pythagorean theorem is,
................................(1)
( It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides )
From the given values the equation (1) becomes,
( 
)
25 + ( 
+ 1 - 2x ) =
25 + 1 -2x = 0 ( ∵ Eliminate in both sides)
26 = 2x
x = 13
Step:2
From the values of x,
a = 5
b = ( 13 - 1 ) = 12
c = 13
Result:
The value of x is 13, from the values of x the values of a,b and c becomes 5, 12 and 13, which is obtained by using Pythagorean theorem.
The tall of the actual building will be 216 feet
Step-by-step explanation:
An architect is presenting a scale model of a building she's designed
to the planning committee of college
1. The scale of the model is 1 inch = 18 feet
2. The tallest wall in the model is 12 inches
3. We need to know how tall the actual building will be
Let us used the ratio method
∵ The scale of the model is 1 inch represents 18 feet
∵ The tallest wall in the model is 12 inch
→ Model(in) : Actual(ft)
→ 1 : 18
→ 12 : h
- By using cross multiplication
∴ 1 × h = 12 × 18
∴ h = 216 feet
∴ The actual height is 216 feet
The tall of the actual building will be 216 feet

Answer:
Step-by-step explanation:
y= -3x+1
you use inverse operations, and since you want the y alone, you subtract 3x on both sides, giving you y= -3x+1
