Step-by-step explanation:

Answer:

h = 16x

Step-by-step explanation:

The volume of a sphere and a cone is same such that,

[tex]V_s=V_c\\\\\dfrac{4}{3}\pi r^3=\dfrac{1}{3}\pi R^2h[/tex]

We have, r = x, R = (1/2)x, h= ? (height of the cone)

So,

[tex]\dfrac{4}{3}\pi x^3=\dfrac{1}{3}\pi (\dfrac{x}{2})^2h\\\\4x^3=\dfrac{x^2}{4}h\\\\h=\dfrac{16x^3}{x^2}\\\\h=16x[/tex]

So, the height of the cone is equal to 16x.

Answer:

x=130

Step-by-step explanation:

Hello There!

Remember the sum of the angles in a triangle is 180

So we can find the missing angle by subtracting the given angles (25 and 25 in this case) from 180

so x = 180 - 25 - 25

180 - 25 = 155

155 - 25 = 130

x = 130

Answer:

27 miles

Step-by-step explanation:

Find the linear equation which is y = 3x

y = 3(9)

y = 27

Answer:

27 miles is the answer

Step-by-step explanation:

x | y

4 |12

5 | 15

6 |18

7 |21

8 | 24

9 |27

 x is increasing by 1 and y by 3 so  by this way 27 is the answer

A and B

Answer: no

Step-by-step explanation:

Steven must have gotten this answer from 11 x 11, which is wrong. The reason is because of the square root.

[tex]\sqrt{11} = 3.3166247903554[/tex]

(roughly 3.32)

So using the formula for a square l x w, the square's area is 11.0224 or 11.02

Answer:

r = 8

Step-by-step explanation:

V = π [tex]r^{2} h[/tex] so 384 = [tex]r^{2} (6)\\[/tex]

384/6 =  [tex]r^{2}\\[/tex] so

64 =  [tex]r^{2}\\[/tex]

8 =  [tex]r\\[/tex]

Answer:

V = 3261.16

Step-by-step explanation:

Given:

P = 1380

r = 8.6% or 0.086

t = 10

Work:

[tex]V=Pe^{rt}\\\\V=1380e^{0.086*10}\\\\V=1380e^{0.86}\\\\V=3261.16[/tex]

Answer:

1.2 packages per dollar

Step-by-step explanation:

Number of packages = 6

Total cost in dollars = $5

Number of packages per dollars = Number of packages / Total cost in dollars

= 1.2 packages per dollar

Let

P = number of packages

d = cost in dollars

k = constant of proportionality

P = k * d

6 = k * 5

k = 6/5

k = 1.2

Constant of proportionality = 1.2

Answer:

In right angled triangle ABC

tan 26=perpendicular/base

tan26 =BC/1050

BC=1050×tan26=512.12m

again

In right angled triangle ADE

tan 38=perpendicular/base

tan38×700=DE

DE=546.9=547m

now

difference in height =547-512.12m=34.8m=35m

35 m is your answer

Josh sees two hot air balloons in the sky as shown. 35m higher is the balloon on the right than the balloon on the left.

Trigonometric ratios for a right-angled triangle are from the perspective of a particular non-right angle.

In a right-angled triangle, two such angles are there which are not right angled(not of 90 degrees).

The slanted side is called the hypotenuse.

From the considered angle, the side opposite to it is called perpendicular, and the remaining side will be called the base.

Josh sees two hot air balloons in the sky as shown.

He determines that the lower hot air balloon is 700 meters away, at an angle of 38 from the vertical.

The higher hot air balloon is 1050 meters away, at an angle of 26 from the vertical.

In right-angled triangle ABC

tan Ф = perpendicular/base

tan26 = BC/1050

BC = 1050 × tan26

BC = 512.12m

In right-angled triangle ADE

tan Ф = perpendicular/base

tan 38 = perpendicular/base

tan38 × 700 = DE

DE = 546.9

DE = 547m

The difference in height = 547 - 512.12m

                                        =34.8m

                                       = 35m

Therefore, 35m higher is the balloon on the right than the balloon on the left.

Answer:

8 c  3     *   6 c 2 =   56 * 15  =   840 ways

Step-by-step explanation:

First, we consider how many ways there are to choose three boys from eight. There are 8 choices for the first boy, 7 for the second, and 6 for the third. However, because the boys are indistinct from one another, we have overcounted, and must divide by 3*2. Similarly, there are 6*5 ways to choose the two girls, divided by 2 for overcounting. Thus, there are (8*7*6*6*5)/(3*2*2)=840 possible quintets.

Answer:

1.96

Step-by-step explanation:

A farmer sells 9.8 kl of apples and pears

4/5 of this weight is apples, while the rest are pears

Therefore the wight of pears can be calculated as follows

Let x represent the weight of pears

9.8= 4/5×9.8 + x

9.8= 0.8×9.8+x

9.8= 7.84+x

9.8-7.84= x

x= 1.96
