Draw a graph which joins the points (155, 100) and (245, 200) and has a slope = 1.1
Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 1.1
Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9

Answers

The solution is "Draw a graph which joins the points (100, 155) and (200, 245) and has a slope = 0.9"

the points are (minute,cost) pairs like the assignment states
the slope is the difference of both costs (90) divided by the minute difference (100)
so k=90/100=0.9

so the last option

The total surface area of a cube is 294cm^2 work out the volume of the cube

Answers

Good morning,

____________________

Answer:

343cm³

____________________

Step-by-step explanation:

total surface = 6r² ⇔ 294=6r²

Then, r²=294÷6=49

Then r=√(49)=7

Therefore the volume = r³=7^(3)=343cm³.

_______________________________…

:)

Answer:

total surface area=6x^2

area=x^3

6x^2=294

x^2=294/6

x^2=49

x=SQR(49)

x=7

x^3=7^3

area=343

What percent of 85 is 72

Answers

Answer:

84.7058824 %

Step-by-step explanation:

Of means multiply and is means equals

P *85 = 72

Divide each side by 85

P *85/85 = 72/85

P = .847058824

Change from decimal form to percent form by multiplying by 100

P =  .847058824 * 100

P = 84.7058824 %

Answer:

84.7058824 %

This is the correct answer.

What is the surface area of the figure? A.
428 ft2

B.
560 ft2

C.
632 ft2

D.
888 ft2

Answers

We have 8 sides to calculate, it will be hard to explain which side I'm calculating without marking on the picture. 

We will start with the front facing side. We can break this up into an 8ft x 8ft square, and a 14ft x 6ft rectangle. The area equals: 
8ft x 8ft + 14ft x 6ft = 148ft^2

The front facing is the same area as is back facing counterpart so we can multiply the surface area by 2:
148ft^2 x 2 = 296f^2

Adding the bottom surface area 6ft x 14ft:
6ft x 14ft + 296ft^2 = 380ft^2

Adding the right side 6ft x 14ft:
6ft x 14ft + 380ft^2 = 464ft^2

Adding the left side 8ft x 6ft:
8ft x 6ft + 464ft^2 = 512ft^2

Adding the 3 sides on the top 8ft x 6ft (top facing), 6ft x 6ft (top facing), and 6ft x 6ft (left facing):
8ft x 6ft + 512ft^2 = 560ft^2
6ft x 6ft + 560ft^2 = 596ft^2
6ft x 6ft + 596ft^2 = 632ft^2

Therefore the answer is C, 632 ft^2.

At a student council meeting, there was a total of 60 students present. Of those students, 35 were female. A. By what percent is the number of females greater than the number of males?
B. By what percent is the number of males less than the number of females?
C. Why is the percent increase and percent decrease in parts A. and B. different?

Answers

There were 28.57 % females greater than the number of males, 40 % males less than the number of females, and the percentage increased and decreased because of the number of females and males.

What is the percentage?

The percentage is defined as a ratio expressed as a fraction of 100.

At a student council meeting, there was a total of 60 students present. Of those students, 35 were female.

number of females = 35

number of males = 60 - 35 = 25

To find percent is the number of females greater than the number of males

(35-25)/35 × 100 = 28.57 %

To find percent is the number of males greater than the number of females

(35-25)/25× 100 = 40 %

The percentage increases and the percentage decreases. In parts a and b because of the number of females and males
