Step-by-step explanation:

Answer:

r = 5

Step-by-step explanation:

if x and y are proportional then 'y = rx' where 'r' is the constant of proportionality

35 = 7r

60 = 15r

100 = 20r

'r' is 5

Answer:

[tex] \displaystyle {r}^{} = 6[/tex]

Step-by-step explanation:

remember that,

[tex] \displaystyle V _{ \rm sphere} = \frac{4}{3} \pi {r}^{3} [/tex]

given that,

thus substitute:

[tex] \displaystyle \frac{4}{3} \pi {r}^{3} = 288\pi[/tex]

divide both sides by 4/3π:

[tex] \displaystyle {r}^{3} = 216[/tex]

cubic root both sides:

[tex] \displaystyle {r}^{} = 6[/tex]

and we are done!

Answer:

1.78 hours

Step-by-step explanation:

If t varies inversely with the speed, the formula for that is  t= \frac{k}{r} .  If t = 2 and r = 40, then we can solve for k, the constant of variation.  Multiply both sides by 40 to get  k = 80.  Now we need to find the value for t when r = 45.  Using the k value we just solved for, we will fill in the equation as  t= \frac{80}{45}   for a t value of about 1.78 hours

Answer:

y = 3x + 1

Step-by-step explanation:

The y - intercept is +1

And the rise over run = 3/1  (because 3 is also 3/1)

Answer:

A) y=3x+1

1 is the y-intercept (it is on the y axis)

you start at the 1 on the graph where the line passes through, then go 3 squares up and 1 to the right to land on the line again. This is rise over run, which you rise 3 squares up from 1, then run 1 square to the right. 3/1 = 3

Step-by-step explanation:

Dan used 2 and 6, and after 3 and 9. If you multiply 2×1.5 = 3, and 6×1.5 = 9, so the ratio is the same and is equal to 1.5

Answer:

Yes

Step-by-step explanation:

2/6 for the first ratio can be reduced to 1/3

3/9 for the second ratio can also be reduced to 1/3

Answer:

[tex]y = \sqrt{ 900 - x\²[/tex]

Step-by-step explanation:

In the complete question, the area of  the roller coaster is:

[tex]x\² + y^2 = 900[/tex]

Required

Solve for y

We have:

[tex]x\² + y^2 = 900[/tex]

Subtract [tex]x\²[/tex] from both sides

[tex]y^2 = 900 - x\²[/tex]

Take positive roots of both sides

[tex]y = \sqrt{ 900 - x\²[/tex]

Answer:

4th option

Step-by-step explanation:

Given

B (- 5, 3 ) → B' (2, 1 )

The change in the x- coordinates are - 5 → 2 , that is + 7

The change in the y- coordinates are 3 → 1 that is - 2

Then the translation rule is

(x, y ) → (x + 7, y - 2 )

If translation moves point B (-5,3) to point B’ (2,1).  Then (X+7, y-2) is the image of (x,y) under this translation

Graph is a mathematical representation of a network and it describes the relationship between lines and points.

Given,

A translation moves point B (-5,3) to point B’ (2,1).

We need to find the image of  (x,y) under this translation

A graph is translated k units horizontally by moving each point on the graph k units horizontally.

Which means to get B' which translation is used.

B (- 5, 3 ) and  B' (2, 1 )

If we add +7 to x coordinate we will get 2.

When we subtract 2 from B we will get 1

So the translation rule is

(x, y ) → (x + 7, y - 2 )

Hence (X+7, y-2) is the image of (x,y) under this translation

Answer:

45 green marbles

Step-by-step explanation:

Green : Blue : Red = 3 : 7 : 5

Fraction of green marbles = [tex]\frac{3}{3+7+5}=\frac{3}{15}[/tex]

Total marbles = 225

Number of green marbles = [tex]\frac{3}{15}*225[/tex]

                                           = 3 * 15

                                           = 45

Start at zero, then go to the left two times, then go down eight more. The new location would be negative ten.

Step-by-step explanation:

Answer:

Step-by-step explanation:

f(1) = 160

f(n + 1) = -2 * f(n)

n = 1

f(2) = -2*f(1)

f(2) = -2*160

f(2) = - 320

f(3) = - 2*f(2)

f(3) = -2 * - 320

f(3) = 640

f(4) = -2 * f(3)

f(4) = -2 * 640

f(4) = - 1280

Answer:

3rd option

Step-by-step explanation:

Cavalieri's principle states that two figures which have the same height and  same cross-sectional area have the same volume

the height of the cylinders are both 42

the diameter of both figures is 24 as the diameter of the second cylinder = 12 x 2 = 24

the radius of the cylinders are both equal to 12

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

A radius is half of the diameter

thus the volumes should be equal
