Mr. Aba builds a circular patio with a diameter of 12 feet. He covers the patio with paving stones. The cost of the paving stones is $10.50 per square foot. To the nearest dollar, how much do the paving stones cost.

A. $126
B. $378
C. $1,187
D. $4,748

Answers

Answer:

C $1187

Step-by-step explanation:

diameter = 12ft

radius = 6 ft

area = πr²

= 3.14×6×6

= 113.04 ft²

paving stones is $10.5 per ft²

paving stones cost = 113.04×10.5 = 1186.92

; the nearest dollar do the paving stones cost is $1187

The answer is A because you have to times 10 by 12 then 50 times 24 and add those two numbers and you will get A

in the addition problem on the right, each letter stands for a digit and different letters stand for different digits. What digits do the letters H,E, and A each represent?
H E
H E
H E
+ H E
____________
A E

Answers

Answer:

This problem is easy but I'll demonstrate an approach for simplifying these kind of problems that can be applied to problems of higher complexity.

Key: Notice that you can write AH as 10A + H and HEE as 100H + 10E+E, and thus

AH +A = HEE

10A + H + A = 100H + 10E +E

11A + H = 100H + 11E

11A = 99H + 11E

A = 9H + E

As H can not be 0 (it is the leading digit in HEE), A must be at least and therefore exactly 9 and the problem solves itself from there on.

Answers

112.5 seconds

First convert minutes to seconds so 7 x 60 + 30, that will get you the total seconds and should equal 450 secs. Divide that by 4: 450 / 4, equals 112.5 seconds

Answer:

112.5 seconds

Step-by-step explanation:

Stephanie ran four laps around the school track in 7 minutes and 30 seconds. How many seconds per lap is that?

You need to do convert 7 minutes in to seconds because you cannot do anything to this unless you convert it.

Remember

1 minute = 60 seconds.

So do 7 times 60.

7 × 60

Which is 420 seconds.

Now add the 30 seconds to that.

420 + 30.

Which is 450 seconds.

Now divided 450 by 4.

450 ÷ 4.

Which is 112.5 seconds per lap.

PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.

Answers

Answer:

You can use the method of substitution and elimination.

Team A : Team B

        3x : 2x

       -12   +12

        5y : 4y

3x-12=5y ---> (1)

2x+12=4y ---> (2)

12x-48=20y

10x+60=20y

12x-48=10x+60

12x-10x=48+60

           = 108

2x=108

x=54

Original number of athletes on Team A = 3(54)

                                                                  = 162

Original number of athletes on Team B = 2(54)

                                                                    = 108

3,6,9,12= 4
2,4,6,8,10,12= 6

So it is 4 and 6

Answers

Answer:1/5

Explanation: 1/35 divided by 1/7= 1/5. 1/7 of/x 1/5= 1/35.

The value of unknown number would be equal to  1/5

How can we interpret the division?

When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.

We need to find the unknown number.

A negative divided by a negative is positive, then;

1/7 of x  is 1/35

1/35 divided by 1/7

1/7 of x 1/5 = 1/35.

x = 1/5

Therefore, The value is x = 1/5

Answer: The second one

Step-by-step explanation:

a store sells laptops for 720 each. this price is 20 percent more than what it cost the store to buy each of them. before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost cost. how much would it cost an employee to purchase one of these laptops at the sale?

Answers

Answer:

462

Step-by-step explanation:

720 is 120% of the store price so to find the store price, we can muliply by the reciprical or 5/6.

720*5/6= 600

The employee can purchase the laptop at 23% off this price or at 77%. Multiply the price by 0.77 to get the employee price.

600*0.77 = 462

The total cost of the laptop at which an employee purchase is 482 and this can be determined by using the unitary method.

Given :

A store sells laptops for 720 each. This price is 20 percent more than what it cost the store to buy each of them. Before the next model's release, store employees can purchase any remaining laptops at 23% off the store's cost.

The following steps can be used in order to determine the total cost of the laptop at which an employee purchase:

Step 1 - The unitary method can be used in order to determine the total cost of the laptop at which an employee purchases.

Step 2 - According to the given data, 720 is the 120% cost at which the store sells. So, the value of the 100% cost is:

[tex]=\dfrac{720}{120}\times 100[/tex]

= 600

Step 3 - Now, the employee can purchase the laptop at a 23% discount that is 77% of the original cost.

Step 4 - So, the total cost of the laptop at which an employee purchase is:

[tex]=\dfrac{77}{100}\times 600[/tex]

= 462

Double bar graph is the only graph that focuses solely on 2 sets of data.

Scatter plot is best at showing frequency and trends and to see the approximate increase/decrease of many data points.
