Answer:

789.6 in³

Step-by-step explanation:

r=d/2

r=15.6/2

r=7.8 in

Then Volume=1/3pier²h

1/3(3.14)(7.8)²(12.4)

1/3(3.14)(60.84)(12.4)

2368.866/3

=789.622

=789.6 in³

Answer:

x = -4

Step-by-step explanation:

Six times a number plus 3 equals three times the same number minus

nine. This equation is 6x + 3 = 3x -9. Next, solve this equation and you get -4. Plug in -4 for x and you should get -21 on both sides.

Step-by-step explanation:

Answer:

2 hours

Step-by-step explanation:

Given the following :

Darryl :

Speed = 25mph

Jacob:

Traveled in opposite direction

Speed = 35mph

After Darryl had traveled for 4 hours, Distance between them was 170 miles

Distance traveled by Darryl :

Speed * time = (25 * 4) = 100 miles

Total distance = distance traveled by Darryl + distance traveled by Jacob

170 miles = 100 miles + distance traveled by jacob

Distance traveled by Jacob = 170 - 100

Distance traveled by Jacob = 70 miles

Time = distance / speed

Time traveled by Jacob = 70 miles / 35mph

Time traveled by Jacob = 2 hours

Answer:

y = 130°

Step-by-step explanation:

4x + 8 + x + 7 + 3x - 19 = 180 (all angles in a triangle add upto 180)

8x = 184

x  = 23°

3x - 19 + y = 180 (supplementary = 180)

sub x = 23 into equation

50 + y = 180

y = 130°

Answer:

130

Answer:

b=−5x+y

Step-by-step explanation:

Let's solve for b.

y=5x+b

Step 1: Flip the equation.

b+5x=y

Step 2: Add -5x to both sides.

b+5x+−5x=y+−5x

b=−5x+y

Answer:

P(-9) = -22 hope this helps! i may be wrong tho, cuz i haven't done this in a while

Step-by-step explanation:

P(-9) = 3(-9) +5

P(-9) = -27+5

P(-9) = -22

Answer:

x = - 1, y = 6

Step-by-step explanation:

Given the 2 equations

y = - 2x + 4 → (1)

y = 6x + 12 → (2)

Substitute y = 6x + 12 into (1)

6x + 12 = - 2x + 4 ( add 2x to both sides )

8x + 12 = 4 ( subtract 12 from both sides )

8x = - 8 ( divide both sides by 8 )

x = - 1

Substitute x = - 1 into either of the 2 equations and solve for y

Substituting into (2)

y = 6(- 1) + 12 = - 6 + 12 = 6

Solution is (- 1, 6 )

Answer:

d + r ≥ 30

$0.75d + $1.25r ≤ $30

Step-by-step explanation:

Given the following :

Number of items to purchase = atleast 30

Total cost must be no more than 30

cost of donut (d) = $0.75

Cost of cinnamon (r) = $1.25

Number of donuts and cinnamon to purchase

To total number of items :

Donut + cinnamon ≥ 30

d + r ≥ 30

Cost of items to purchase :

Cost = price per item * number of items

$0.75d + $1.25r ≤ $30

Answer:

Denise should plan to spend 36 minutes walking back.

Step-by-step explanation:

Let 'x' reflect the amount of time spent running in hours, then 3-x represents the time spent walking in hours.

here , we know,

           [tex]Distance= Speed \times time[/tex]

Given the values ,

[tex]Distance= 8x[/tex]  

[tex]speed=2mph[/tex]

[tex]Time=(3-x)hours[/tex]

Now , putting these values ,

[tex]8x=2(3-x)[/tex]

[tex]8x=6-2x[/tex]

[tex]10x=6[/tex]

[tex]x=\frac{6}{10}[/tex]

[tex]x=\frac{3}{5}[/tex]

[tex]\frac{3}{5} \times 60[/tex] = 36minutes (converting hours into minutes that is 1 hour = 60 minutes )

Hence , the answer is 36 minutes .

Given:

The area of a square garden = 100 sq. ft

To find:

The perimeter of the garden.

Solution:

Let the side of the square garden be a.

Area of a square = [tex]a^2[/tex]

So, [tex]a^2=100[/tex].

Taking square root on both sides.

[tex]a=\pm \sqrt{100}[/tex]

[tex]a=\pm 10[/tex]

Length of side cannot be negative. So, a=10. It means, side length of the garden is 10 ft.

Perimeter of square = 4a.

Perimeter of square garden is

[tex]4(10)=40[/tex]

Therefore, the perimeter of the square garden is 40 ft.

Answer:

The diameter of the circle = 10 cm

The radius of the circle= 10/2= 5 cm

Area of the circle = pi r^2

= pi 5^2

=3.14 *25

= 78.5 cm ^2
