Answer:

m = 28

Step-by-step explanation:

70 × 2 = 5m

140 = 5m

28 = m

Step-by-step explanation:

I guess, "you" and "I" are working with the same efficiency and work rate.

and with the typos in it, it is not clear, if I understood the problem and the given data properly.

but based on what I understood :

so, 3.6 customers in 0.5 hours.

7.5 hours × 2 = 15 times 0.5 hours.

15 × 3.6 = 54 customers.

so, with the same work rate as you, I helped 54 customers in 7.5 hours.

Answer:

The selling price of the shoes is $26.46.

Step-by-step explanation:

Given the following question:

8% of 24.50

To find the answer we will use the formula to calculate percentages, we multiply the percentage by the cost, then we divide that answer by 100. Finally, we add that answer to the original costs of the shoes to have our answer.

[tex]\frac{p~x~n}{100}[/tex]

[tex]\frac{8~x~24.50}{100}[/tex]

8 × 24.50 = 196

196 ÷ 100 = 1.96

8 of 24.50 is 1.96

Now Add

[tex]24.50+1.96=24.46[/tex]

The selling price of the shoes are $26.46.

The linear equation is y = 1000 + 120x, at the end of 6 months, Joe will have $1720 in his account and Joe needs to save for at least 18 months in order to afford the down payment.

Data;

a)

The linear equation to compute the amount of money (y) he has after x months of savings

This can be written as

[tex]y = 1000 + 120x\\[/tex]

b)

Graphing this line, see attachment

c)

The amount Joe has after 6 months

[tex]y = 1000 + 120x\\x = 6\\y = 1000 + 120(6)\\y = 1000 + 720\\y = 1720[/tex]

after 6 months, Joe will have $1720 in his account.

d)

Joe needs $3160 down payment for a car, he would have to save x number of months.

[tex]3160 = 1000 + 120x\\120x = 3160 - 1000\\120x = 2160\\\frac{120x}{120} = \frac{2160}{120} \\x = 18[/tex]

Joe needs to save for at least 18 months in order to afford the down payment.

Answer:

the error term measures the same sources of variance as the numerator of the F-ratio

Answer:

5 < x ≤ 7

Step-by-step explanation:

perimeter = 2x + x + x + 2 = 4x + 2

perimeter is more than 22 so 22 is less than perimeter , then

22 < 4x + 2 ≤ 30 ( subtract 2 from each interval )

20 < 4x ≤ 28 ( divide each interval by 4 )

5 < x ≤ 7

You have the correct answer. Nice work.

=======================================================

Explanation:

Let's say Phil passes his brother at a sign post, and let's say the sign post is x miles into the 6 mile hike. This means 0 < x < 6.

Once Bill reaches the sign post, he turns around to walk back x miles. His faster brother Phil bikes the remaining 6-x miles to the trail end, before coming back to bike an additional 6 miles to get to the trailhead again. Phil arrives back at the same moment Bill does.

Overall, Phil travels 6-x+6 = 12-x miles in the same amount of time Bill walks back x miles. I recommend drawing out a number line diagram to see why this is the case.

-------------

For Bill, we have this equation

distance = rate*time

x = r*t

r = x/t

Phil has the equation

distance = rate*time

12-x = (3r)*t

Notice that Phil's rate is three times that of Bill. The t is the same for both brothers because they travel in the same timespan.

Plug in r = x/t and solve for x. The t variables divide and cancel.

12-x = 3*(r)*t

12-x = 3*(x/t)*t

12-x = 3x

12 = 3x+x

4x = 12

x = 12/4

x = 3

Phil passed Bill at the 3 mile marker.

This is why the answer is choice B.

Answer:

41

Step-by-step explanation:

76, x and 63 are linear pair angles.

Sum of linear pair angles is 180,

76 + x + 63 = 180

x + 76 + 63 = 180

x + 139 = 180

x = 180 - 139

x = 42

Answer:

15 cm squared

Step-by-step explanation:

First we solve the area for the first triangle:

h(b)/2 = area

3(5)/2 = 7.5

Now since there are 2 triangles, we multiply it by 2 to get the area of both put together :)

Answer:

  15 cm²

Step-by-step explanation:

The formula for the area of a parallelogram is ...

  A = bh

Using the given dimensions, we find the area to be ...

  A = (5 cm)(3 cm) = 15 cm²

Brand C is the cheapest per ounce among Brand A and Brand B. So option B is the correct answer

Brand A is a 16-ounce can and costs $0.89

Brand B is a 32-ounce can and costs $1.75.

Brand C is sold as three 16-ounce cans and costs $2.65.

If two expressions are connected with equal sign is called equation.

16a=0.89

32b=1.75

3(16c)=2.65

a=0.055

b=0.0546

c=0.0552

Therefore brand B is the cheapest per ounce

Answer:

i have the same question

Step-by-step explanation:

it is positive 7

Answer:

I think it would be 568 I'm not the best at math though so I might be wrong

So, first we have to put in an equation

9/20+ 2 9/10

multiply 9/10 by 2

So you get 9/20+ 2 18/20

Add the fractions together and you'll get 26/20

since their isn't a whole number a whole number it's just 2 and 26/20 reduce it to

2 and 9/5

I hope this is right. This is how I was taught.

Radius: 2.1Inches

Step-by-step explanation:

Circumference

Circumference is the linear distance around the circle edge.

Radius

The radius of a circle is any of the line segments from its center to its perimeter. The radius is half the diameter or r = d

2

.

Diameter

The diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. The diameter is twice the radius or d = 2·r.

The Greek letter π

π represents the number Pi which is defined as the ratio of the circumference of a circle to its diameter or π = C

d

. For simplicity, you can use Pi = 3.14 or Pi = 3.1415. Pi is an irrational number. The first 100 digits of Pi are: 3.1415926535 8979323846 2643383279 5028841971 6939937510 5820974944 5923078164 0628620899 8628034825 3421170679
