Answer

a. The volume is multiplied by 4

b. The volume is doubled

Explanation

a. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the radius is doubled, the new volume will be [tex]\pi (2r)^2h/3[/tex], which is equal to [tex]4\pi r^2h/3[/tex]. This means that the volume is multiplied by 4.

b. The volume of a cone with radius r and height h is [tex]\pi r^2 h/3[/tex]. If the height is doubled, the new volume will be [tex]\pi r^2(2h)/3[/tex], which is equal to [tex]2\pi r^2 h/3[/tex]. This means that the volume is multiplied by 2.

Answer:

A) -2/5 gal/min

B) 25 minutes

C) 7.5 minutes

Step-by-step explanation:

A) We are told that the tank contains 12 gallons of water when Jada first sees it.

5 minutes later, it loses two gallons to become 10 gallons.

Thus, rate at which the amount of water in the tank changing = -2/5 gal/min

B) After 5 minutes it contains 10 gallons. Since it drains at 2/5 gal/min, let us say the time to finish draining all is x, thus;

2/5 • x = 10

x = 10 × 5/2

x = 25 minutes

C) When full, it can hold up to 15 gallons. This is 3 more than the 12 she saw when she arrived.

Thus;

2/5 • y = 3

y = 5 × 3/2

y = 7.5 minutes

Answer:

72 square inches

Step-by-step explanation:

The surface area is the sum of all the sides' areas.

**I am assuming the pyramid is a square pyramid based on observation.

There is one 4 by 4 square: area = [tex]4^2=16[/tex]

There are 4 congruent triangles with height 7 and base 4: area of a single triangle = 1/2 * b * h; [tex]\frac{7*4}{2}=14[/tex]

14 * 4 = 56

Add 56 and 16 = 72

Step-by-step explanation:

Let us assume the cost of the video game be x

There should be two chances

The first one is

that the cost of the video game should be equivalent to the amount given

SO

The return is $0

The second one is

When the cost of the video game is less than the amount you pay

SO, the return change is

= $50 - x

Answer:

Well 40.21/12.5=3.217 so it is about $3.22 per sqr ft.

Answer:

153.86in^2

Step-by-step explanation:

Area of a circle = πr²

Where : = π = pi = 3.14

R = radius = 14/2 = 7

the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.

7² x 3.14 = 153.86

A radius is half of the diameter

Answer:

Mid point:

[tex] = ( \frac{3 + - 5}{2} , \: \frac{1 + 8}{2} ) \\ = ( - 1, \: 4.5)[/tex]

distance:

[tex] = \sqrt{ {( - 5 - 3)}^{2} + {(1 - 8)}^{2} } \\ = \sqrt{64 + 49} \\ = \sqrt{113} \\ = 10.6 \: units[/tex]

slope:

[tex] = \frac{1 - 8}{ - 5 - 3} \\ = \frac{ - 7}{ - 8} \\ = \frac{7}{8} [/tex]

Answer:

1.10119047619 use first 3 digits for answer

Answer:

1  17/168

Step-by-step explanation:

3 1/3 is the same as 3 4/12

-2 1/4 is the same as -2 3/12

3 4/12 + (-2 3/12) = 1 1/12

1 1/12 + 1/56 = 13/12 + 1/56

we can use 168 as a common denominator to get:

13/12 = 182/168

1/56 = 3/168

add the above together to get 185/168 which is 1  17/168

Answer:

261.80 mm³

Step-by-step explanation:

the volume is 1/3 of the volume of a cylinder with the same measurements (ground area times height).

so, v = pi × r^2 × h × 1/3

r=5

h=10

v = pi × 5^2 × 10 × 1/3 = pi × 250/3 = 261.80 (261.7993878...)

Answer:

Area cover by solar panel to face = 9,600 feet²

Step-by-step explanation:

Given:

Length of Solar panels = 240 feet

Width of Solar panels = 40 feet

Find:

Area cover by solar panel to face

Computation:

Area of rectangle = Length × Width

Area cover by solar panel to face = Length of Solar panels × Width of Solar panels

Area cover by solar panel to face = 240 × 40

Area cover by solar panel to face = 9,600 feet²

Answer:

Area cover by solar panel to face = 9,600 feet², The panels are about 340 feet Long, and 40 feet Wide. The area of this rectangle is a Length x Width.

Answer:

7.193 ft

Step-by-step explanation:

    |\

    |   \

    |      \

    |         \

h  |            \      10 ft

    |               \

    |                  \

    |            46°   \

    ---------------------

For the 46° angle, h is the opposite leg. The hypotenuse is 10 ft. The sine is the trig ratio that relates the opposite leg to the hypotenuse.

sin A = opp/hyp

sin 46° = h/10

h = 10 sin 46°

h = 7.193

Answer: 7.193 ft

Answer:

b² - 4ac > 0

Step-by-step explanation:

Conditions for the discriminant

• If b² - 4ac > 0 then 2 real and distinct roots

• If b² - 4ac = 0 then 2 real and equal roots

• If b² - 4ac < 0 then no real roots

Here the roots are x = 0 and x = 4

That is 2 real and distinct roots , then

b² - 4ac > 0

The hypotenuse is (root) 84.25

Step-by-step explanation:

4.5^2 + 6^2 = x^2 (hypotenuse)

20.25 + 36 = 84.25

x^2 = 84.25

x = (root) 84.25 or 9.1787...
