The length of a rectangle is 5 in longer than its width.
If the perimeter of the rectangle is 74 in, find its length and width.
Answers
Answer:
Length = 21
Width = 16
Step-by-step explanation:
We know that the formula for perimeter is:
P=2W+2L
And we also know that:
L=W+5
So then we put all that we know in the formula:
74=2W+2(W+5)
Now we expand the brackets and do some algebra:
74=4W+10 (-10)
64=4W (÷4)
16=W
Now that we know the width we can pop that into the length equation:
L=16+5
L=21

A car rental agency charges $70 per day, which includes 100 miles. For each mile over 100 miles, there is an additional cost of $0.40 per
Write an equation relating m, the number of miles driven, if the total cost for a one-day rental was $212.
Answers
Answer:
212=70+(m X 0.40)
If $212 is the total cost for a one-day rental, the number of miles driven is 455 miles.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
We have,
Cost of car rent per day for 100 miles = $70
Additional cost per mile = $0.40
Let m = number of miles driven
Total cost for one day rental = $212
The equation that represents the additional m = miles driven for a day that cost $212 is:
212 - 70 = 0.40m
142 = 0.40m
m = 142 / 0.40
m = 355
This means 355 additional miles were driven.
The number of miles driven for the day is:
= 100 + 355
= 455 miles
Thus if $212 is the total cost for a one-day rental, the number of miles driven is 455 miles.

Answers
The inequality expression for the number of years when tree will be atleast 20 feets tall is x ≥14
Current height = 2 Growth rate = 1.3 feets per yearThe height of the tree after x years can be represented as a linear equation thus :
Height = 2 + 1.3xNumber of years when the tree will be 20 feets tall :
20 = 2 + 1.3x 20 - 2 = 1.3x 1.3x = 18x = 13.84The tree would be atleast 20 feets tall in 14 years x this can be expressed thus

state the gradient and the y-axis intercept of
y=3x+7
Answers
Step-by-step explanation:
the slope (or gradient) of a line is the factor of x.
in our case here : 3
it is expressed as ratio y/x and represents the amount of units y changes (and via the sign in what direction), when x changes a certain amount of units (again, via the sign in what direction). like when going from a point 1 to a point 2.
so, here we have 3 = 3/1, and that means, when x changes by 1 unit to the right (positive), y changes 3 units up (positive).
the y-axis intercept is simply the point, where x = 0. clearly, any point with the x coordinate being unequal to 0 cannot be on the y axis.
so, here
y = 3×0 + 7 = 7
=>
the y-axis intercept point is (0, 7).

45 is what percent of 60 as an equation
Answers
Answer:
75% of 60 = 45
Step-by-step explanation:
In order to find the answer to this question you need to divide the percentage of the number by one-hundred and then divide that number by the number the number you are trying to find the percentage of.
60/x=100/75
(60/x)*x=(100/75)*x
60=1.33333333333*x
(1.33333333333) to get x
60/1.33333333333=x
45=x
x=45
75% of 60 = 45

Marsha has $400 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have in total in 1 year?
Answers
The total amount in the account after 1 year will be $420
Based on the information given, the following can be deduced:
Principal = $400
Interest rate = 5%
Time = 1 year
Therefore, the simple Interest will be:
= PRT/100
= ($400 × 5 × 1)/100
= $2000/100
= $20
Therefore, the amount will then be:
= Principal + Interest
= $400 + $20
= $420
Therefore, the total amount is $420

A) Dilated 150% then reflected across the x-axis
Step-by-step explanation:
By counting the squares of shape A, you can see that 2 squares = 100% and 1 square = 50%. You can then count 2 squares into shape B (because that is your starting point) and then count the remaining squares, which is 3. 3 squares is equal to 150% so we know there is a 150% dilation.
We can then also see shape A has been reflected across the x-axis to give shape B.
