Answer:

Step-by-step explanation:

the formula for the circumference of a circle is 2rπ

the formula for the area of a circle is (r^2)π

the formula for the diameter of a circle is 2r

π=3.14

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

1. diameter =2r.    since diameter=24, r=12

2. circumference=2rπ.     since circumference = 314.     314=2rπ       r=49.9746

3. circumference=2rπ                                           area=(r^2)π

   since r=7, circumference=14π=43.98229      since r=7, area is 49π=153.9380

4. Since the diameter is 20 the radius is 10. so just insert it into the formulas as before:    circumference=20π=62.8318 and area=100π=314.15926

5.  the formula for the diameter is 2r=d        2(18)=d,    36=d

6. 2rπ=circumference = 2(5)π=10π=31.415926

Hope that helps :)

Answer:

False.

Step-by-step explanation:

Answer:

k =  -9

Step-by-step explanation:

f(x) = 2x²+kx-20

From remainder theorem,

x = 10 and f(10) = 90

f(10) = 90

Subsitute the value of x into the expression above.

f(10) = 2(10²)+10k-20 = 90

200+10k-20 = 90

Solve for k by collecting like terms

10 k = 90+20-200

10k = 110-200

10k = -90

k = -90/10

k = -9.

Hence the value of the constant is -9

Answer:

126 miles

Step-by-step explanation:

If I remember right, you'll have to multiply 30 by 4.2 and get 126 miles since each hour is 30 miles.

Answer:

the second option im pretty sure

Answer:

4/48. I don't know for sure, but I think B is the correct answer

Given:

A train is traveling at a constant speed in miles per hour.

The table of value is:

Hours (x)     Miles (y)

     1                  20

     2                 100

     3                 180

     4                 260

     5                 340

To find:

The equation for the given data table.

Solution:

It is given that the train is traveling at a constant speed in miles per hour. So, it is a linear relationship.

Choose any two point from the given table of value. Let the two points are (1,20) and (2,100). So, the equation of the line is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

[tex]y-20=\dfrac{100-20}{2-1}(x-1)[/tex]

[tex]y-20=\dfrac{80}{1}(x-1)[/tex]

[tex]y-20=80(x-1)[/tex]

Add 20 on both sides.

[tex]y=80(x-1)+20[/tex]

[tex]y=80x-80+20[/tex]

[tex]y=80x-60[/tex]

Therefore, the correct option is D.

Step-by-step explanation:

Answer:

smaller number = 17, larger number = 34

Step-by-step explanation:

Let x be the smaller number and y be the larger nuber

x + y = 51 --(1)

y - 17 = x  --(2)

Sub (2) into (1)

y - 17 + y = 51

y = 34

Put y = 34 into (2)

34 - 17 = x

x = 17

Ans: smaller number = 17, larger number = 34

Answer:

Let get large number is x and small number as y.

sum of two numbers is 51.(small number + large number = 51)

ie. x +y =51 --------(1)

The smaller number is 17 less than the larger number.

x-y = 17 ------------(2)

(1) +(2);

(x + y ) + (x - y) = 51 +17

2x = 68

x=34

Substituted for (1);

x + y =51

34 + y =51

y= 51  -34

y= 17

Answer:

dependant

Step-by-step explanation:

Answer:

Step-by-step explanation:

Area = L x W      gym area is (5x + 5x) ft²      if   W = 5x      Find the L

Area = L x W       divide both sides by W

Area/W  = (L x W) / W

Area/W  =  L  =  Area/W

    L = Area/W

       =  (5x + 5x) / (5x)

       =  5x( 1 + 1) / 5x

       =  5x(2) / 5x                      the 5x's cancel each other  5x/5x = 1

       =   2 ft          I got 2.  I suspect the 12 was a typo and should have been 2

Answer:

25 flowers 14 bushes

Step-by-step explanation:

13f/23b = 308

16f/21b = 306

8f/260 = 308

25 · 6 = 150

14 · 10 = 140

140+150 = $290

Sarah can buy 25 flowers and 14 bushes considering her budget.

An equation is the statement of two expressions located on two sides connected with an equal to sign. The two sides of an equation is usually called as left hand side and right hand side.

Let x be the number of flowers and y be the number of bushes.

Total expense = $300

Cost for each flower = $6

Cost for each bush = $10

We get an equation,

6x + 10y = 300

(a) 13 flowers and 23 bushes

Total cost = (6 × 13) + (10 × 23) = $308

(b) 16 flowers and 21 bushes

Total cost = (6 × 16) + (10 × 21) = $306

(c) 8 flowers 26 bushes

Total cost = (6 × 8) + (10 × 26) = $308

(d) 25 flowers 14 bushes

Total cost = (6 × 25) + (10 × 14) = $290

Hence the possible combination is 25 flowers and 14 bushes.

Answer:

11.28m

Step-by-step explanation:

The computation of the height of the spire is shown below:

let us assume the height of the spire be x

Now

For triangle ABD

Tan 43 degrees = h ÷ x

x = h × cot 43 degrees

= 1.07236 h

For triangle ABC

tan 15 degrees = h ÷ (30 + x)

0.2679 = h ÷ 30 + 1.07236h

8.038 + 0.28728 h = h

h = 11.28m

Answer:

122

Step-by-step explanation:

if you do 730 divided by 6 the answer is 121.6666667 so you round it up to 122

Find liters per day by dividing the amount made by the number of days :

10 liters / 2 days = 5 liters per day.

Find how much more he needs to make by subtracting the amount made from the total he wants:

15 liters - 10 liters = 5 liters more needed.

Divide amount needed by time:

5/5 = 1

He will need to spend 1 more day, which means he will spend a total of 3 days to make 15 liters.
