Answer:
70 square inches
Step-by-step explanation:
We have to find the area of the rectangle and this would help us determine how much paint he would need to paint his rectangle
Area of a rectangle = Length × Width
Length = 10 inches
Height = 7 inches
Area of the rectangle = 10inches × 7 inches
= 70 square inches
Therefore, he would be needing 70 square inches of paint in order to paint his rectangel

The statement which is true of the right triangles ABC and DEF is Area of ABC is greater than area of DEF.
What is Right Angled Triangle?Right angled triangle are those triangle for which one of the angle is 90 degrees.
Given two right angled triangles, ABC and DEF.
Area of a triangle = 1/2 × base × height
Area of ΔABC = 1/2 × 14 × 6
= 42 square units
Base of ΔDEF = √(7² + 4²) = √65
Height of ΔDEF = √(5² + 8²) = √89
Area of ΔDEF = 1/2 × √65 × √89
= 38.03 square units
Hence the correct option is Area of ABC is greater than area of DEF.

At a fast food restaurant, one hamburger and five small fries cost $8.74. If two hamburgers and
three small fries cost $7.75, what is the cost of one hamburger?
Answer:
1 hamburger costs $1.79
Step-by-step explanation:
y = total cost
h = hamburger
f = fries
h + 5f = 8.74 (Multiply this by -2)
2h + 3f = 7.75
-2h - 10f = -17.48
2h + 3f = 7.75
-7f = -9.73
f = 1.39
h + 5f = 8.74
h + 5(1.39) = 8.74
h + 6.95 = 8.74
h = 1.79

How many more miles per gallon does Mrs. Sanchez get than Mr. White?

Let x represent number of gallons and y represent numbers of miles.
Mr. White
# of gallons miles
2.5
76
5
152
15
456
18
547.2
miles per gallon
Answer:
5.6 miles per gallon
Step-by-step explanation:
Equation for Mrs Sanchez: y = 36x
The rate of change = miles/gallon for Mrs Sanchez = 36 miles/gallon
Let's find the rate of change for Mr White:
Rate of change = change in y/change in x
Using two pairs of values form the table given, (2.5, 76) and (5, 152),
Rate of change = (152 - 76)/(5 - 2.5) = 76/2.5
Rate of change = miles/gallon = 30.4 miles/gallon
The difference between the miles per gallon of Mrs Sanchez and Mr White = 36 - 30.4 = 5.6 miles per gallon.
Therefore, Mrs Sanchez gets 5.6 miles per gallon than Me White

-3/4 x 2/5
Which situation can be modeled by the expression?
A. Zach owes 3/4 of the original price of his car. Each month he pays 2/5 of the original price. How many months will it take Zach to pay off his car?
B. Zach owes 3/4 of the original price of his car. Each month he pays 2/5 of how much he still owes on the car. What fraction of the original price does Zach owe after this month’s payment?
C. Abdi owes Kim 3/4 of a dollar. He needs to borrow more money from Kim. Abdi then borrows 2/5 of how much he owes. By what fraction of a dollar does the amount Abdi owes Kim change?
D. Abdi owes Kim 3/4 of a dollar. He pays her 2/5 of how much he owes. What fraction of a dollar does Kim receive from Abdi?
Answer:
D.
Step-by-step explanation:
The situation that can be modeled by the expression -3/4 x 2/5 is:
Abdi owes Kim 3/4 of a dollar. He pays her 2/5 of how much he owes.
The expression -3/4 x 2/5 gives us the fraction of a dollar that Kim receives from Abdi, which is -3/10 of a dollar.
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.com
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
The expression -3/4 x 2/5 means that we multiply -3/4 by 2/5.
Multiplying two fractions involves multiplying their numerators together and their denominators together. So,
-3/4 x 2/5 = (-3 x 2) / (4 x 5) = -6/20 = -3/10
Therefore,
The situation that can be modeled by the expression -3/4 x 2/5 is:
Abdi owes Kim 3/4 of a dollar. He pays her 2/5 of how much he owes.
The expression -3/4 x 2/5 gives us the fraction of a dollar that Kim receives from Abdi, which is -3/10 of a dollar.

−3x+6y+5=−7 how do i solve this
Answer:
Step-by-step explanation:
You can simplify this, but not "solve" it. Subtracting 5 from both sides yields
-3x + 6y = -2.
You could graph this easily by finding the x- and y-intercepts. To find the x-intercept, set y = 0: -3x + 6(0) = -2. Then x = 2/3 and the x-intercept is (2/3, 0).
To find the y-intercept, set x = 0: -3(0) + 6y = -2, or y = -1/3 => (0, -1/3)
Plot these two intercepts and draw a line through them.

Answer:
Total interest to be paid: $210
Total amount to be repaid: $3,710
Step-by-step explanation:
You can ignore the monthly payment for this problem.
For simple interest, the formula is I = PRT where I = interest earned, P = principal amount borrowed/deposited, R = rate as a decimal, and T = time in years.
I = (3,500)(0.06)(1)
I = 210
Then add that to the amount borrowed ($3,500) and you're done.
3,500 + 210 = $3,710

how many times larger is the volume of a cylinder if the radius is tripled?
Answer:
9 times larger
Step-by-step explanation:
The volume (V) of a cylinder is calculated as
V = πr²h ( r is the radius, h the height )
Ir is tripled , that is r = 3r , then
V = π × (3r)² h = 9πr²h
That is the volume is now 9 times larger
