Answer: The ratio is 18:3

Step-by-step explanation:

Answer: 6 to 1

Step-by-step explanation:

A ratio refers to a fraction. In this case the question asks how many players to coaches there are.

The word "to" means that is where the fraction bar goes.

Players/Coaches

There are 18 players and 3 coaches.

18/3

18 can be divided by 3, 6 times so the fraction can be simplified to

6/1 meaning there are 6 players for every coach.

Select the expression below that would form an identity with the given expression.

Expression: 18m – 30

Help pls. Also wdym this is to short yk why so long >:/

Answers

Answer:

Y= mx + b

so Y = 1/3x + 2

just substitute

Due to the answer requesting slope intercept form, one shall use the points (3,2) in order to substitute for b. Slope intercept form is formatted in y = mx + b, which m would be your slope, which in this particular problem was given; therefore, y = 1/3x +b.

Now, we shall use points (3,2) as the substitutes for the solution for b, which 3 would be the input and 2 would be y.

Therefore, 2 = 1/3(3) + b
2 = 1 + b, therefore, one would be subtracted from 2 which would give us the answer of b equaling to one. Thus, y = 1/3x + 1

A Ferris wheel has an area of 50 square meters. Find
the radius of the Ferris wheel to the nearest meters.
Round the answer to the nearest whole meter.

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

The radius of the Ferris wheel to the nearest meters will be 4 meters.

What is the area of the circle?

It is the close curve of an equidistant point drawn from the centre. The radius of a circle is the distance between the centre and the circumference.

Let r be the radius of the circle. Then the area of the circle will be

A = πr² square units

A Ferris wheel has an area of 50 square meters. Then the radius is calculated as,

πr² = 50

r² = 15.915

r = 3.989

r ≈ 4 meters

The radius of the Ferris wheel to the nearest meters will be 4 meters.

An American traveling in Japan wishes to exchange American money for Japanese money. If the exchange rate is $1 = 80 yen, then how many dollars will the traveler need to purchase 10,000yen?

Answers

Answer: $125

Step-by-step explanation:

1/80=x/10,000

10,000/80=125

Hope this helped!

Answer:125 yen

Step-by-step explanation:
Ratio and proportion

Ratio=1:80=x:10,000

x represents dollars which is unknown

1/80=x/10,000

Then you cross multiply

80x=10,000

80x/80=10,000/80

x=125

Therefore,$125 will give you 10,000yen

Cell phone company A charges $40 a month, with 500 free minutes and $0.10 a minute after that. Cell phone company B charges $25 a month and all minutes cost $0.05.

Answers

A = 40 + .1(M-500) for M>500

B = 25 + .05M

20 minutes a day for 30 days = 600 minutes per month

A(600) = 40+.1(100) = $50

B(600) = 25 + .05(100) = $30

Plan B is less expensive

40+.1(M-500)= 25+.05M

40-25- .1(500) = .05-.1M

.05M = 35
M= 35/.05 = 700 minutes will have the same cost under plan A or B

40+.1(200) = $60 under plan A
25+.05(700) = $60 under plan B
