One way to solve this is to look at the size of the poster, and then subtract the size of the picture so you have the area that needs to be painted left.
Area of square poster - 3x × 3x = 9x^2
Area of painting - 2x × 2x = 4x^2
9x^2 - 4x^2 = 5x^2
The area is 5x^2
Answer:
d = 70t
Step-by-step explanation:
The units of speed tell you how to write the equation.
speed = miles/hour
Multiplying by hours gives ...
speed · hours = miles
Using the required variables and the given speed, you have ...
70t = d . . . . . time in hours, distance in miles
Answer:
The measurement of arc AD is 53°
The measurement of arc BC is 39°
Step-by-step explanation:
Let
x----> the measurement of arc AD
y---> the measurement of arc BC
we know that
The measure of the internal angle is the semi-sum of the arcs comprising it and its opposite
so
m∠DEA=(1/2)[x+y]
substitute the value
46°=(1/2)[x+y]
92°=[x+y] -----> equation A
The measurement of the external angle is the semi-difference of the arcs which comprises
m∠P=(1/2)[x-y]
substitute the value
14°=(1/2)[x-y]
28°=[x-y] -----> equation B
Adds equation A and equation B
92°+14°=2x
x=106°/2=53°
Find the value of y
substitute in the equation A the value of x
92°=[53°+y]
y=92°-53°=39°
Answer:
19 Cars
Step-by-step explanation:
Write a linear equation:
y=7x+53
Y = Total money
X = cars parked
If we want to earn 186 dollars a day then sub y for 186 and solve x:
186=7x+53
186-53=7x
133=7x
7x=133
x=133/7
x=19
This means that he will need to park 19 cars a day to earn a total of 186 dollars in one day.
