Answer: 86

Step-by-step explanation:

Since we want to know the number of walking plans that she will do on the 15th day, we have to use 14 days in our calculations as the first day isn't included.

Therefore, the equation to solve this will be:

= 2 + 6d

where,

d = number of days = 14 days

= 2 + 6d

= 2 + 6(14)

= 2 + 84

= 86

Answer: it’s 8 to 14 number c

Step-by-step explanation:

Let me know if I’m wrong

The ratio equivalent to 20 to 35 is 8 to 14.

Option C is the correct answer.

The ratio shows how many times one value is contained in another value.

Example:

There are 3 apples and 2 oranges in a basket.

The ratio of apples to oranges is 3:2 or 3/2.

We have,

20 to 35

This can be written as,

= 20/35

= 5 x 4 / 5 x 7

= 4/7

Now,

5 to 7 = 5/7

7 to 5 = 7/5

8 to 14 = 8/14 = 4/7

14 to 8 = 14/8 = 7/4

Thus,

20 to 35 is the same as 8 to 14.

Answer:

6 + 8 + 10 = 24

Step-by-step explanation:

Take 6 and 15 and compare those two, you will have to multiply 6 by 2.5 to get to 15 and that's the dilation, then dive 20 and 25 by 2.5, you'll get 8 and 10.

6 + 8 + 10 =24

Answer:

To start off, we know the problem involves something with volume as it is 3D and has a cubic in it.

We know r = 5, h = 30, and v = 1500

The volume for a cylinder in 3d is : V=[tex]\pi[/tex][tex]r^{2}[/tex]h

We're solving for the height when the cylinder has a volume of 1500, therefor, we will solve for height.

Using our volume equation we plug in all values except h because we're solving for it.

1500=[tex]\pi r^{2} h[/tex]

1500=[tex]\pi 5^{2} h[/tex]

1500=25[tex]\pi[/tex](h)

1500/25[tex]\pi[/tex] = h

60/[tex]\pi[/tex] = h

60/[tex]\pi[/tex] = 19.0985

H is 19ft. (C)

Answer:

The equation in the slope-intercept form will be:

y  = 1/4x - 7

Step-by-step explanation:

Given the points

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-4,\:-8\right),\:\left(x_2,\:y_2\right)=\left(-8,\:-9\right)[/tex]

[tex]m=\frac{-9-\left(-8\right)}{-8-\left(-4\right)}[/tex]

[tex]m=\frac{1}{4}[/tex]

We know that the slope-intercept of line equation is

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

where m is the slope and b is the y-intercept

substituting m = 1/4 and the point (-4, -8) to find the y-intercept 'b'

y = mx+b

-8 = 1/4(-4)+b

-8 = -1 + b

b = -8+1

b = -7

so the y-intercept = b = -7

substituting m = 1/4 and b = -7 in the slope-intercept form of line equation

y = mx+b

y  = 1/4x + (-7)

y  = 1/4x - 7

Thus, the the equation in slope-intercept form will be:

y  = 1/4x - 7

c i think lmk if I got this

To cover a floor with an area of 10 square foot, 5 tiles is needed.

Area is the amount of space enclosed by a two-dimensional figure.

If the tile is 2 feet long and twice as long as they are wide, suppose that the tile is a rectangle, then the area of each tile will be:

Area of tile = l x w

where l = 2 feet

w = 1 foot

Area of tile = 2feet(1 foot)

Area of tile = 2 ft^2

To determine how many tiles are needed to cover a 10 foot square floor, divide the area of the floor with the area of each tile.

# of tiles = Area of floor/Area of each tile

# of tiles = 10 ft^2/2ft^2

# of tiles = 5

Answer:

i is about 23.5 so you could say c)

Step-by-step explanation:

The line segment is RST.

Since RS is 1/3 of the total length, ST is 2/3.

Therefore, 2(RS) is = ST, and RS + ST = RT.

2(3x -20) = 4x - 11

6x - 40 = 4x - 11

2x = 29

x = 14.5

3(14.5) - 20 = 23.5

4x - 11 = 47

2(23.5) = 47

The length of RS is 23.5.

The length of ST is 47.

The total length of RT is 70.5.
