58 out of 120 as a percent

Answers

48.33%

Explanation:
Simple way to find percentages of two numbers, is to make it into a fraction.
58/120 then divide 58 by 120.
You can also multiply 58•100 then divide by 120 to get it in a percentage without having to convert.
Which is .4833(33)
Or 48.33%

If Diana walks forward and her angle looking to the top of the building changes to 40°, how much closer is she to the building? Round the answer to the nearest tenth of a foot. 10. 3 ft 17. 6 ft 30. 2 ft 97. 2 ft.

Answers

The closer Diana gets to the building, the smaller the angle becomes

Diana is 17.6 feet closer to the building

How to calculate the distance from the building

To calculate the distance between her and the building, we make use of the following tangent ratio

[tex]\tan(\theta) = \frac{h}{d}[/tex]

Where:

[tex]\theta = 40^o[/tex]h represents the height of the building; h = 130d represents the distance from the building

So, we have:

[tex]\tan(40) = \frac{130}{d}[/tex]

Make d the subject

[tex]d = \frac{130}{\tan(40)}[/tex]

Evaluate tan(40)

[tex]d = \frac{130}{0.8391}[/tex]

[tex]d = 154.93[/tex]

Initially, Diana is at a distance of 172.53.

The difference in both distance is:

[tex]\Delta d = 172.53 - 154.93[/tex]

[tex]\Delta d = 17.6[/tex]

Hence, Diana is 17.6 feet closer to the building

If your slope is -1/3 how do you move vertically?

Answers

Answer:

You move vertically by -1 units

Step-by-step explanation:

The slope is rise over run.

This slope means you go down 1 unit as you go to the right 3 units

This is a graph with a negative slope, so it comes from the top left to the bottom right.

-Chetan K

[tex]\huge\fbox{Hello\:there!}[/tex]

Remember, one of the ways we can find the slope is

[tex]\rm\displaystyle\frac{Rise}{Run}[/tex]

Where

[tex]\rm{\underline{Rise}}[/tex] is the amount of units we move up or down (vertically)

[tex]\rm{Run[/tex] is the amount of units we move left or right (horizontally)

So, given the slope

[tex]\displaystyle-\frac{1}{3}[/tex]

how many units do we move vertically?

Let's look at the slope.

As we can see, the Rise is -1. (Answer)

Thus, we move

-1 units vertically. (1 unit down)

How many cups of broccoli florets would 1 pound of broccoli produce?

3/4 lb broccoli = 3 cups of florets

Answers

Answer:

4 cups

Step-by-step explanation:

wt. cups

3/4 lb. 3

1 lb. ?

4/3*3 = 4 cups

1 pound of broccoli would produce 4 cups of broccoli florets.

Given that 3/4 pound (or 0.75 pounds) of broccoli produces 3 cups of broccoli florets.

If we assume that the ratio remains constant, we can calculate the approximate number of cups of broccoli florets in 1 pound of broccoli:

1 pound of broccoli is equal to 1.33 times the weight of 3/4 pound of broccoli (since 1 pound is 1.33 times larger than 3/4 pound).

So, multiplying 3 cups by 1.33 gives us 3.99 cups of broccoli florets in 1 pound of broccoli.

Therefore, 1 pound of broccoli would produce 4 cups of broccoli florets.

Step-by-step explanation:

if it was without the coupon the fee would be the $2 per mile (2x) with the $35 which would be

y = 2x

What is the y intercept of this radical function if right will mark brainlist

Answers

Answer:

y = -2

Step-by-step explanation:

The y-intercept is the y-coordinate of the point where the curve intersects (crosses) the y-axis, i.e. when x = 0.

Therefore, to find the y-intercept, substitute x = 0 into the function:

[tex]f(0)=\sqrt[3]{0+1} -3=\sqrt[3]{1} -3=1-3=-2[/tex]

Therefore, the curve crosses the y-axis at (0, -2) and so the y-intercept is

y = -2.

will it take them to do one loop if the tracks are 20m long?

Answers

The number of minutes that will take them to do one loop in a track of 20 m long is approximately 4 minutes

The speed of the toy engine around the Christmas tree is 300 meters/hour.

The number of minute for them to do one loop if the track are 20m long is as follows:

1 loop = 20m distance

Therefore,

Speedspeed = distance / time

300 = 20 / t

t = 20 / 300

t = 1 / 15 hours

t = 3.9999999996

t ≈ 4 minutes

Answer:

Step-by-step explanation:

Ok, so we know that the horizontal distance between the points is 6 and the vertical distance is 8.  Using the Pythagorean theorem we know that 8^2+6^2=d^2 (d is the distance between points). When solving we get

8^2+6^2=d^2

64+36=d^2

Mike is reading instructions for assembling a tree house. The instructions include a scale drawing of the floor plans of the tree house that shows the floor as a square with 4-inch-long sides. The scale of the drawing is 12 inch = 2 feet. If Mike were to build a tree house according to the floor plans, what would be the area of the floor of the tree house in square feet? _________

Answers

Answer: 144 square feet

Explanation: It says that the square has sides that are 4 inches long, which means that all of the sides are 4 inches long. If two inches is 12 feet, then all you have to do is multiply it by 2, since the sides are 4 inches. That means that all sides are 24 ft long. Now just calculate the area by multiplying the length and the width to get 144 square feet.
