Answer 1

Answer:

7. 86.25 8. 18.75

Step-by-step explanation:

Answer 2

Answer:

7. Answer is 1236.25$

8. Answer is 143.75$

9. Answer is 16.485$

10. Answer is 6.825$

11. Answer is 31.25%

12. Answer is 0.125 for the decimal section and 12.5% for the percent section.

Step-by-step explanation:

7. 7.5 percent of 1150 is 86.25 and 86.25 + 1150 is 1236.25.

8. 15 percent of 125 is 18.75 therefore 125 + 18.75 is equal to 143.75.

9. 3.50 + 2.25 + 9.95 + 15.7 and 5 percent of 15.7 is 0.785 and 15.7 + 0.785 is 16.485.

10. 4.25 plus 2.25 is 6.50 and 5% of 6.50 is 0.325 and 6.50 plus 3.25 is 6.825.

11. 63 plus 25 is 88 so 88 is 68.75 percent of 128 and 100 minus 68.75 is 31.25 so 31.25 is the answer.

12. 1/8 is 12.5 percent so for the percent section it is 12.5 and for the decimal section 0.125

Diego has $10 and begins saving $2 each week toward buying a new phone. At the same time that Diego begins saving, Lin has $50 and begins spending $2 per week on supplies for her art class. Is there a week when they have the same amount of money?Write an equation and answer.

Answers

Answer:

no

Step-by-step explanation:

the easiest way to find out is to plot these on a graph

for Diego's function, we will write the total amount of savings (or his goal) = the amount hes saving multiplied by the weeks he saves + the amount he started with

y = 2x + 10 (in blue in attached file)

same with Lin

y = 2x + 50 (in red in attached file)

if the lines cross at any point, then that point on the two lines is the same value of x AND y, otherwise, one or the other is a different value

beings as these two lines have the same rate of change, they will not cross, meaning that neither will have the same amount if the rate continues

yes
on week 11 they will both have $30
please correct me if im wrong
because

A car travels 625.68 miles and uses 9.9 gallons of gas. What is the unit rate for gas?

Answers

Let’s make this into an expression then. Huh. A mile for a 16 thousandth of gas. You must have a pretty good car, dude.

Answer:

63.2:1

Step-by-step explanation:

We can find the unit rate by making equations that will help us solve.

We need to find how many miles the car travels in one gallon.

We can divide 625.68 by 9.9.

625.68/9.9 = 63.2

The car travels 63.2 miles on one gallon of gas.

Meaning that the unit rate is 63.2:1.

Hope this helps. Have a nice day.

On a balanced scale are a 25-g mass, a 100-g mass, and five identical blocks marked X as shown. What is the mass of each block marked X? Write an equation illustrated by this balanced scale. I really need help with this.

Answers

Answer:

One block - 15

Two blocks - 30

Three blocks - 45

Four blocks - 60

Five blocks - 75

Equation: 25 + 5x = 100

Step-by-step explanation:

This is a pretty simple problem. The scale is balanced and from what we know, the 100 and 25 are on different sides. If we want the scale to be balanced, then we have to solve the equation:

25 + 5x = 100.

(We have the 5x because we have 5 blocks that are marked as x)

subtract 25 from both sides

25-25 + 5x = 100-25

5x = 75

the following step is to divide both sides by 5.

5x/5 = 75/5

x = 15

Now that the equation is solved, we know that ONE blocked marked as X equals 15-g.

(All five of them equal 75-g)

Answers

Answer: x=40 y=140

Step-by-step explanation:

To work out x:

The angles in a triangle always add up to 180.

You already have one angle which is 50 the bottom left angle is a right angle and right angles always equal 90. To work out x, do 50+90=140 then do 180-140=40.

To work out y:

Angles on a straight also add up to 180.

So as you have figured out what x is (40) you would take it away from 180 to give you y.

180-40=140

Hope this helps :)

In the diagram below, line segment AC is the perpendicular bisector of line segment EF. Is line segment EF the perpendicular bisector of line segment AC? Explain how you know

Answers

Answer:

Not necessarily. If picture is drawn to scale, no.

Step-by-step explanation:

Line segment EF is certainly perpendicular to line segment AC, but we don't know if it bisects or not.

If the picture isn't drawn to scale, there is no way to know if EF is a perpendicular bisector to AC or not because we do not know if AD = CD.

If the picture is drawn to scale, EF is not a perpendicular bisector to AC because we can see that AD ≠ CD and therefore EF cannot be a perpendicular bisector.
