FERRIS WHEEL The Ferris wheel at an amusement park has a radius of 10.2 meters. A rider, who is sitting level with the center of the Ferris wheel, is 13.1 meters above the ground. At what height above the ground is the rider when the wheel rotates another 140°? Round to the nearest tenth if necessary.

Answers

Answer:

19.7 m

Step-by-step explanation:

Draw a circle to represent the ferris wheel with a 10.2 m radius. Draw a horizontal line through the circle center horizontal to the ground (at 13.1 m). Now draw a line from the center of the circle (ferris wheel) upward at 140 degrees until you reach the edge of the circle. Draw a line down from that point to the horizontal line at This is your right triangle to solve.

Hypotenuse is 10.2 m (radius of circle)

The angle of the triangle the supplementary angle of 140 degrees. 180-140=40 degrees

sin 40 degrees=rise /radius=rise/10.2

sin 40=0.6428=rise/10.2

rise=10.2(0.6428)

rise=6.6 m

13.1+6.6=19.7 m

What is the y intercept of the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3)

Answers

So the y intercept is at +5 so you’d draw a line going through (-3, -3) and make it cross the y-intercept which is at (0, 5) and you should be good

The line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

What is the equation of a line?

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation of a line is y=-3/4x+5 and the coordinate point is (-3, -3)

Here, slope of a line is -3/4.

The slope of a line perpendicular to given line is m1=-1/m2

Now, the slope of a line is -4/3

Substitute m= -4/3 and (x, y) =(-3, -3) in y=mx+c, we get

-3=-4/3 (-3)+c

c=-7

Substitute m= -4/3 and c=-7 in y=mx+c, we get

y=-4/3x-7

Therefore, the line perpendicular to the line y=-3/4x+5 that includes the point (-3,-3) is y=-4/3x-7.

Answers

Answer:

Step-by-step explanation:

First you have to calculate CB in order to use sin law to calculate ∠A

CB=[tex]\sqrt{18.4^{2} -13.2^{2} }[/tex]

CB=12.8(correct to nearest tenth)

After that, use sin law to calculate ∠A,

because it says she is taller so you add both

Height of Amy who is 5 cm taller than Jack is 1.83 meters.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Jack is 1.78 m tall and Amy is 5 cm taller than Jack.

Therefore, The sum of the height of Jack and 5 cm more is the height of

Amy.

Therefore,

178 cm + 5 cm = 183 cm is the height of Amy. (1m = 100 cm)

So, 183 cm is equal to 1,83 meters.

Which of the following is equivalent to 10 – 4x < 50?

Step-by-step explanation:

 Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

If QRS = MNP, QR = 11, QS = 15, MP = 2x + 1, S = 84, R = 32, and M = (17y - 4),

find the values of x and y.

pls answer quick

Answers

Answer:

x = 7 and y = 4

Step-by-step explanation:

If QRS = MNP, then QR = MN, RS = NP and QS = MP

Given

QR = 11

QS = 15

MP = 2x + 1

Recall that QS = MP

15 = 2x+1

2x = 15-1

2x = 14

x = 14/2

x = 7

Similarly

<Q = <M

<Q + <R + <S = 180

<Q + 32 + 84 = 180

<Q + 116 = 180

<Q = 180 - 116

<Q = 64 degrees

Since <M = 17y - 4

64 = 17y - 4

17y = 64+4

17y = 68

y = 68/17

y = 4

Hence x = 7 and y = 4

Savannah is making a quilt with squares that have side lengths of 15/16 foot each. Are the side lengths of the squares closer to 1/2 foot or 1 foot long? ​

Answers

Answer:

1 foot long

Step-by-step explanation:

If this fraction is closer to one it will be close to 16/16. And since 8 is half of 16, any fraction that is around 8/16 is closer to 1/2. 15 is closer 16 so this fraction is closer to one.

The side lengths of the squares is closer to 1 foot when rounded to the nearest foot length

What is rounding up numbers?

There are basically two rules while rounding up numbers

If the number you are rounding is followed by 0, 1, 2, 3, or 4, round the number down and if the number you are rounding is followed by 5, 6, 7, 8, or 9, round the number up.

Non-zero digits are always significant

Zeros between non-zero digits are always significant

Leading zeros are never significant

Trailing zeros are only significant if the number contains a decimal point

Given data ,

Let the side lengths of the squares after rounding be represented as A

Now , the value of A is

The side lengths of the quilt with square shape be = 15/16 foot

Now , on rounding the value 15/16 , we get

A = 0.9375 feet

And , the value of A is much closer to 1 foot

Therefore , the value of A is 1 foot

Hence , the side lengths of the squares after rounding is 1 foot

Under her cell phone plan, Peyton pays a flat cost of $48 per month and $3 per gigabyte. She wants to keep her bill at $60.60 per month. Write and solve an equation which can be used to determine gg, the number of gigabytes of data Peyton can use while staying within her budget.

Answers

Answer: 4.20 gigabyte

Step-by-step explanation:

Based on the information given in the question, the equation that can be used to determine the the number of gigabytes of data Peyton can use while staying within her budget will be:

48 + 3g = 60.60

3g = 60.60 - 48

3g = 12.60

g = 12.60/3

= 4.20

The number of gigabytes of data is 4.20g

Answer:

Equation: 3g+48=60.6

b) p=160.25-m

c)p=m+160.25

d)p=200.25m+160.25

Answers

Answer:

bB

Step-by-step explanation:

The correct equation which represents the relationship in the table is,

⇒ p = m + 160.25

Where, m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

This table represents the relationship between m, the amount of money an employee has in the morning, and p, the amount of money an employee has later in the day after they receive their paycheck.

Hence, By all options, we can check by substitute the given values.

So, By option 3;

The equation is,

⇒ p = m + 160.25

Substitute m = 200.25,

⇒ p = 200.25 + 160.25

⇒ p = 360.50

Thus, The correct equation which represents the relationship in the table is,

⇒ p = m + 160.25
