Answer:

  V = (2/3)(11)

Step-by-step explanation:

The given cylinder has a height of 2r, so its volume is ...

  V = πr²(2r) = 2πr³

The volume of a sphere is given by ...

  V = 4/3πr³

Then the ratio of the volume of the sphere to the volume of the cylinder is ...

  (4/3πr³)/(2πr³) = (4/3)/2 = 2/3

So, the volume of the sphere is 2/3 times the volume of the cylinder:

  V = (2/3)(11)

Answer:

(x-6)/(x-2)

Step-by-step explanation:

(x^2-4x-12)=(x^2+2x-6x-12)

X(X+2)-6(X+2)

(x-6)(X+2)

(x^2-4)

= (x-2)(x+2)

Answer:

x = 60°

Step-by-step explanation:

Angles on the circle formed by the same arc are congruent, then

∠ BDC = ∠ BAC = 50°

x = 180° - (70 + 50)° ← sum of angles in triangle = 180°

x = 180° - 120° = 60°

Answer:

-3.6 degrees

Step-by-step explanation:

Since we need to find the temperature that is 3 miles above ground we first need to multiply the distance above ground by the decrease in temperature per mile.

3 * 5.2 = 15.6

Now that we have the total decrease in temperature at that altitude we subtract it from the temperature at ground level. This gives us the final temperature at 3 miles above the ground.

12 - 15.6 = -3.6

Finally, we can see that the temperature is -3.6 degrees

Answer: 131 magazines per hour

Step-by-step explanation:

Peggy delivered 328 magazines in 2.5 hours.

To find out the rate at which she delivered these magazines, divide the number of magazines by the time taken to deliver them:

= Magazines / Time in hours

= 328 / 2.5

= 131 magazines per hour

Answer: No, she is right

[tex]\frac{2x^2+7x+3}{4x+12}[/tex]

Factor the trinomial, what two numbers multiply to equal 6 but add to equal 7. That is 6 and 1.

[tex]\frac{2x(x+3)+(x+3)}{4(x+3)}[/tex]

The (x+3) will cancel

Answer:

A linear function that relates y to x is:

[tex]y\:=\:\frac{2}{3}x\:+\:5[/tex]

The graph of the linear function is also attached.

Step-by-step explanation:

Given the table

x          -3           0              3             6

y          3           5               7            9

The slope-intercept form of the line equation

[tex]y = mx+b[/tex]

where

Taking two points (-3, 3) and (0, 5) from the table to determine the slope of the linear function

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                 =  [5 - 3] / [0 - (-3)]

                 = 2 / 3

Thus, the slope of the line = m = 2/3

We know that the value of the y-intercept can be determined by setting x = 0 and determining the corresponding value of y.

From the table, it is clear

at x = 0, y = 5

Thus, the y-intercept b = 5

substituting m = 2/3 and b = 5 in the slope-intercept form of the line equation

[tex]y = mx+b[/tex]

[tex]y\:=\:\frac{2}{3}x\:+\:5[/tex]

Therefore, a linear function that relates y to x is:

[tex]y\:=\:\frac{2}{3}x\:+\:5[/tex]

The graph of the linear function is also attached.

Answer: x=20/3=6.67

Step-by-step explanation:

To solve proportions, the most useful way is to use [cross multiplication], where we not multiply horizontally but as diagonally.

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

Given

x:10=9:6

Cross Multiply

9·x=6·10

9x=60

Divide 9 on both sides

9x/9=60/9

x=20/3=6.67

Answer: See explanation

Step-by-step explanation:

Let the width of the rectangle be x.

The length of a rectangle is 3 times as big as the width. Length = 3x

New width = x + 4

New length = 3x + 4

The new area will be:

a = (3x + 4)(x + 4)

a = 3x² + 12x + 4x + 16

a = 3x² + 16x + 16

Step-by-step explanation:

total ratio is 5

first find the total amount

bob's ratio is 2/5

so 2/5 ×total amount=8 pounds

0.4 ×total amount=8 pounds

total amount=8/0.4=20 pounds

so chris receives: 20-8=12 pounds

Answer:

okay so first you have the original height (2,000 feet) than subtract by 450. add 1750 giving you 3300

Answer:

24

Step-by-step explanation:

Multiply 5 * 10

5 * 10 = 50

1,200/50 = 24

The result of 1,200 divided by 5 times 10 is 2,400.

To solve the expression, follow the order of operations (PEMDAS/BODMAS):

1,200 ÷ 5 × 10

Step 1: Perform division first:

1,200 ÷ 5 = 240

Step 2: Perform multiplication:

240 × 10 = 2,400

So, the result of 1,200 divided by 5 times 10 is 2,400.

Answer:

d. V = 668.2 ft³

Step-by-step explanation:

[tex]V = \frac{1}{2}bhl\\V = \frac{1}{2}(8.6)(8.4)(18.5)\\V = 668.2ft^{3}[/tex]

Answer:

[tex]\boxed {\boxed {\sf D. \ V \approx 668.2 \ ft^3}}[/tex]

Step-by-step explanation:

The volume of a triangular prism is found using this formula:

[tex]V=\frac{1}{2} bhl[/tex]

For this prism, the base is 8.6 feet, the height is 8.4 feet, and the length is 18.5 feet.

[tex]b= 8.6 \ ft \\h= 8.4 \ ft \\l= 18.5 \ ft[/tex]

Substitute the values into the formula.

[tex]V= \frac{1}{2} (8.6 \ ft) (8.4 \ ft) ( 18.5 \ ft)[/tex]

Multiply the first two numbers in parentheses.

[tex]V= \frac{1}{2} (72.24 \ ft^2) ( 18.5 \ ft)[/tex]

Multiply again.

[tex]V= \frac{ 1}{2} (1336.44 \ ft^3)[/tex]

Multiply by 1/2 or divide by 2.

[tex]V= 668.22 \ ft^3[/tex]

Round to the nearest tenth. The 2 in the hundredth place tells us to leave the 2 in the tenth place.

[tex]V \approx 668.2 \ ft^3[/tex]

The volume is about 668.2 cubic feet.

Answer: The next fraction in the sequence will be 5/20.

Step-by-step explanation:

9/20 is the first fraction.

2/5 is equal to 8/20, so that is the second fraction.

7/20 is the third fraction.

3/10 is equal to 6/10, so that is the fourth fraction.

By now we can see that there is a pattern, because the first fraction's numerator began with 9, the next 8, then 7, and 6. We also simplfied all he fractions so that they had the denominator 20. Because of this, the next fraction in the sequence will be 5/20.
