Answer:

181.75 in2 (inches squared)

Step-by-step explanation:

Surface area is all the areas of the sides added up. in this case, it would be calculated as follows:

2×8×2.5 = 2 long sides of box = 40

2×6.75×2.5 = 2 short sides of box = 33.75

2×6.75×8 = 2 faces of box = 108

40 + 33.75 + 108 = 181.75

The area of a rectangle is 4y + 10.

A. Represent the area of the rectangle in factored form.
B. Use the factored form to give one possible set of dimensions for this rectangle.

Answers

The area of a rectangle = 4y+10
= 2(2y+5)
So, the area of the rectangle in factored form is 2(2y+5)
B) Use the factored form to give one possible set of dimensions for this rectangle.
Area of rectangle = length x width
The area of the rectangle in factored form is 2(2y+5)
Substitute y = 1
The area of the rectangle = 2(2(1)+5)
= 2 x 7
So, one possible set of dimensions for this rectangle is 2 x 7

Answers

Answer: Eleven Fourths xEight Ninths.

Step-by-step explanation: To get the mixed number Eleven Fourths, you have to multiply 4x2 (4 as the denominator and 2 as the whole number) to get 8, and add 3 (numerator) to get 11, and then put 4 over it as the original denominator to get 11/4. Then, just plug back in the numbers: 11/4 x 8/9 (Eleven-Fourths times Eight-Ninths)

Answers

Answer: 35/3

Step-by-step explanation: To turn mixed numbers into improper fractions, the general rule is to :

multiply the denominator (of the fraction in the mixed number) by the whole number in the mixed number, and then adding the numerator (of the fraction in the mixed number) to give the new numerator in the improper fraction. The denominator stays the same as the one in the mixed number.

So, (denominator X whole number) + numerator = numerator of improper fraction.

the denominator=3

the whole number=11

the numerator=2

So, (3 X 11) + 2 = 35=numerator of improper fraction.

(The denominator stays the same.)

The table of values represents a linear function g(x), where x is the number of days that have passed and g(x) is the balance in the bank account:

x g(x)
0 $600
3 $720
6 $840

Part A: Find and interpret the slope of the function. (3 points)

Part B: Write the equation of the line in point-slope, slope-intercept, and standard forms. (3 points)

Part C: Write the equation of the line using function notation. (2 points)

Part D: What is the balance in the bank account after 7 days? (2 points)

Answers

Answer:

Part A:

The slope of the function is 40.

m=Y2 - Y1/ X2 - X1

720 - 600 / 3 - 0 = 120/3 = 40

40 is the balance in the bank account in one day.

Part B:

Point-slope form: y - 600 = 40(x - 0)

Slope intercept: y = 40x + 600

Standard form: 40x - y = -600

Part C:

g(x) = 40x + 600

Part D:

After 7 days, the bank account will have a $280 balance.

The Hydro water department has a monthly service charge of $13.90 and a volume charge of $1.45 for every 100 cubic feet of water.

The total monthly cost is equal to the service charge plus the charge for the volume used during the month. If we let x represent the number of cubic feet of water (in hundreds) and y represent the total monthly cost, then we have:
total monthly cost = volume charge + service charge
y = 1.45x + 13.90

If the Johnson family used 200 ft3 more water this month than last month, then they can expect
A. an increase in their water bill of $2.90.

B. an increase in their water bill of $27.80.

C. a decrease in their water bill of $2.90.

D. a decrease in their water bill of $27.80.

Answers

Answer: A

Step-by-step explanation:

In this question, you can disregard the initial $13.90 cost because we're only looking for an INCREASE in price. If the Johnson family used 200 cubic feet MORE of water, we need to multiply 2 * 1.45 which gets us 2.90. We multiply 2 by 1.45 because 200 represented in x is 2, since x is represented in hundreds.
