Since we know that 1 foot is 12 inches, we can determine that a half of a foot is 6 inches. We have 7 feet, so we need to multiply 12 and 7 to find 7 feet in inches. 12*7 is 84, but we still have to add in our additional 6 inches. When we add 6 to 84, we get 90. Therefore, the classroom door is 90 inches tall.
Answer:
( x +4)^2 + ( y-7)^2 = 36
Step-by-step explanation:
We can write the equation of a circle as
( x-h)^2 + ( y-k)^2 = r^2
where ( h,k) is the center and r is the radius
( x- -4)^2 + ( y-7)^2 = 6^2
( x +4)^2 + ( y-7)^2 = 36
Answer:
20 degrees
Step-by-step explanation:
a triangle's angle sum is 180 degrees, so you would subtract 180-60=120 because angle q is 60 degrees less than 180. now add 40 to 120 to equal 160 then subtract 160 from 180 to equal 20 degrees
Greg has walked miles
<em><u>Solution:</u></em>
Given that, Greg’s house is 0.8 miles from the library
Distance between house and library = 0.8 miles
Greg has walked of the distance
Therefore,
Distance walked = of the distance between house and library
Here "of" means multiplication
Thus we get,
Thus Greg has walked miles
