An escalator in the mall rises to a platform and makes a 30 degrees angle with the ground. If the platform is 76 feet above the ground, how long is the escalator?

Answers

Answer 1

9514 1404 393

Answer:

  152 feet

Step-by-step explanation:

A triangle modeling the situation has the unknown length as its hypotenuse, and the given platform height as the side opposite the angle. The relevant trig function is ...

  Sin = Opposite/Hypotenuse

  sin(30°) = (76 feet)/(escalator length)

  escalator length = (76 feet)/sin(30°) = (76/0.5) feet

  escalator length = 152 feet

Answers

Answer:

x=5

Step-by-step explanation:

If the sum of the measures of angle M and R is 90 degrees, and you know that angle R is 55 degrees, subtract angle R from the total angle. Then, solve for M

90 - 55 = 35

5x + 10 = 35

a particular tree is 18 m tall : a model of it was built with a. scale of 4 cm : 3m how tall is the model.

Answers

Answer:

24 cm

Step-by-step explanation:

We can set up a ratio of 18 m / x cm = 3 m / 4 cm because we know that it's a scale.

Cross multiplying, we get 3x = 72. Divide both sides by 3 and we have x = 24 cm.

We can also consider it by just dividing 18 m by 3 m to find the scale factor, which is 6. We then multiply the 4 cm by 6 to get 24 cm as well.

A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?

Answers

Answer:

a)1 cup of flour

b)67.5 minutes

Step-by-step explanation:

a) A recipe requires 3 cups of flour to make 27 dinner rolls. How much flour is needed to make 9 rolls?

From the above question, we know that:

27 dinner rolls = 3 cups of flour

9 dinner rolls = x

Cross Multiply

27 rolls × x = 9 rolls × 3 cups

x = 9 rolls × 3 cups/27 rolls

x = 1 cup of flour

Hence, 1 cup of flour is needed to make 9 dinner rolls

b) Mandy runs 4 km in 18 min. She plans to run in a 15 km race. How long will it take her to complete the race?

From the above question:

4 km = 18 minutes

15km = x

Cross Multiply

4km × x = 15km × 18 minutes

x = 15km × 18minutes/4km

x = 67.5 minutes

Hence, in a 15km race , it would take her 67.5 minutes to complete her race.

Pakisagutan lang po help pls​

Answers

Answer:

Step-by-step explanation:

S  50 m = 0.050 km

A  ∵ 1 m = 100 cm

    ∴ 5 m = 500 cm

K  ∵ 1000 dm = 0.1 km

    ∴ 1 dm = [tex]\frac{0.1}{1000}[/tex] km

    ∴ 5246 dm = [tex]\frac{0.1}{1000}\times 5246[/tex] km

                        = 0.5246 km

P ∵ 1 m = 1000 mm

  ∴ 5.246 m = 5246 mm

P ∵ 1 hg = 1000 dg

   ∴ 3.7 hg = 3700 dg

U  ∵ 1 g = 100 cg

   ∴ 0.37 g = 37 cg

E  ∵ 1 kg = 1000 g

   ∴ 370 kg = 370,000 g

solve each system of equations algebraically y= x-6 y= 2x

Answers

Answer: x = -6

Step-by-step explanation: The problem gave us the y value, so we can just substitute it into the equation and solve it.

y = x - 6

y = 2x

2x = x - 6 (substitute the y value into the equation)

1x = -6 (subtract x on each side)

x = -6 (1x is basically saying x so you do not need to divide)

A baker sold 35% of the cakes she baked, if she baked 80 cakes, how many cakes did she sell?

Answers

Answer:

28

Step-by-step explanation:

find 35% off 80 cakes

35% * 80

Converting percent to decimal:

35%/100 = 0.35

0.35 * 80

28

Therefore the baker sold 28 cakes out of the 80 cakes she baked. Hope this helps!

I think 35% of 80 is 28.

If Bill works on Saturdays, he earns $9 per hour (h), plus a $10 bonus for working on the weekend. He wrote a Function, f(h) = 9h + 10, to help calculate how much he would earn working different numbers of hours next Saturday. How much will Bill earn for 5 hours and 12 hours?

Answers

Answer:

[See Below]

Step-by-step explanation:

For 5 hours: f(5)

f(5) = 9(5) + 10

f(5) = 45 + 10

f(5) = 55

Bill would work earn $55 if he worked for 5 hours.

For 12 hours: f(12)

f(12) = 9(12) + 10

f(12) = 108 + 10

f(12) = 118

Bill would work earn $118 if he worked for 12 hours.

Peaches are being sold for $2 per pound.The customer created a model to represent the total cost of peaches bought. If x represents the number of pounds of peaches bought and y represents the total cost of the peaches, which best describes the values of x and y?

The values of both x and y can be any real number.
The values of both x and y will be real numbers greater than or equal to 0.
The value of x and y will always be zero
The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Answers

Answer:

B - The values of both x and y will be real numbers greater than or equal to 0.

The answer choice that best describes the values of x and y is B - The values of both x and y will be real numbers greater than or equal to 0.

Calculations and Parameters:

Given that peaches are being sold for $2 per lb.

If we define x as the number of pounds that you buy, and y as the cost of these peaches, we can write the function:

y = $2*x

Therefore, the best description of the values of x and y is found in option B. The value of x can be any real number greater than or equal to 0, but the value of y must be an integer greater than or equal to 0.

Jada and Noah wanted to find the total volume of a cube and a rectangular prism. They know that the prisms volume is 20 cubic units, and they know that the cube has side lengths of 10 units. Jada says the total volume is 27,000 cubic units. Noah says it is 1,020 cubic units. Do you agree with either of them?

Answers

Answer:

Noah answer is the correct answer

Step-by-step explanation:

The solution to the above question is given as:

Total Volume = Volume of the prism + Volume of the cube

Volume of the prism = 20 cubic units

Volume of a cube = (Side length)³

= 10³ = 1000 cubic units

Hence: The total volume =

20 cubic units + 1000 cubic units

= 1,020 cubic units

Therefore, I agree with Noah's answer.

Write the equation of the line in slope intercept form that passes through the point (-3, 5) and is parallel to y= - 2/3x

Answers

Answer:

[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]

Step-by-step explanation:

We want to find the equation of the line that is parallel to:

[tex]\displaystyle y=-\frac{2}{3}x[/tex]

And passes through (-3,5).

First, we need to determine the slope of our new line.

Remember that parallel lines have the same slope.

Since the slope of our original line is -2/3, this means that the slope of our new line must also be -2/3.

Now, we can use the point-slope form given by:

[tex]y-y_1=m(x-x_1)[/tex]

We will let (-3, 5) be (x₁, y₁). By substitution:

[tex]\displaystyle y-(5)=-\frac{2}{3}(x-(-3))[/tex]

Simplify:

[tex]\displaystyle y-5=-\frac{2}{3}(x+3)[/tex]

Distribute:

[tex]\displaystyle y-5=-\frac{2}{3}x-2[/tex]

Add 5 to both sides. So, our equation is:

[tex]\displaystyle y=-\frac{2}{3}x+3[/tex]

Answer:

[tex]\displaystyle y = -\frac{2}{3}x + 3[/tex]

Step-by-step explanation:

5 = –⅔[–3] + b

2

[tex]\displaystyle 3 = b \\ \\ y = -\frac{2}{3}x + 3[/tex]

Parallel equations have SIMILAR RATE OF CHANGES [SLOPES], so –⅔ remains as is.

A). Scale factor = [tex]\frac{1}{4}[/tex]

B). Length of the unknown side = 2.75 feet

Step-by-step explanation:

Part A

Since, the large rectangle was scaled by a scale factor 'k' to form the smaller rectangle,

Scale factor = [tex]\frac{\text{Side length of the image}}{\text{Side length of the preimage}}[/tex]

                    = [tex]\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}[/tex]

                    = [tex]\frac{4}{16}[/tex]

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

Part B

Scale factor = [tex]\frac{\text{Side length of the smaller rectangle}}{\text{Side length of the larger rectangle}}[/tex]

[tex]\frac{1}{4}=\frac{\text{Side length of the smaller rectangle}}{11}[/tex]

Therefore, side length of the unknown side = [tex]\frac{11}{4}[/tex] = 2.75 feet

At a state fair, each person pays $8 for admission plus $2 for each ride. While at the fair, Elizabeth goes on 6 rides. Which expression can be used to find the total amount Elizabeth spends?

Answers

Answer:

The expression is given as:

Total amount = 8 + 2x

Total amount = $20

Step-by-step explanation:

Let the number of rides Elizabeth goes on be represented by x

The expression used to find the total amount =

$8 + $2 × x

= 8 +2x

Elizabeth goes on 6 rides

Total amount =

8 + 2 × 6
