Find M please in this Geometry question.

Answers

Answer:

m = 8

Step-by-step explanation:

As we can see we have two similar triangles

These are triangles FDH and GEF

mathematically, when two triangles are similar, the ratio of their corresponding sides are equal;

Thus;

DH/DF = EG/EF

12/15 = m/10

15 * m = 12 * 10

15 m = 120

m = 120/15

m = 8

Which of these contexts describes a situation that is unlikely?
O Rolling a 1 on a standard six-sided die, numbered from 1 to 6.

O Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue.

O Winning a raffle that sold a total of 100 tickets if you bought 9o tickets.

OReaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.​

Answers

Answer:

The first one

Step-by-step explanation:

This is because all the other ones there is a likely chance that you will get them. While the first one it is less of a chance that you will role a die and land on a one. It is a 1 out of 6 chance

The situation which is unlikely is rolling a 1 on a standard six-sided die, numbered from 1 to 6

What is Probability?

The probability that an event will occur is measured by the ratio of favorable examples to the total number of situations possible

Probability = number of desirable outcomes / total number of possible outcomes

The value of probability lies between 0 and 1

Given data ,

a)

Rolling a 1 on a standard six-sided die, numbered from 1 to 6

Probability P ( A ) = 1/6

P ( A ) = 0.1667

b)

Spinning a spinner divided into four equal-sized sections colored red/green/yellow/blue and landing on red or yellow or green or blue

Probability P ( A ) = 1

P ( A ) = 1

c)

Winning a raffle that sold a total of 100 tickets if you bought 90 tickets.

Probability P ( A ) = 90/100

P ( A ) = 0.9

d)

Reaching into a bag full of 10 strawberry chews and 10 cherry chews without looking and pulling out a strawberry or a cherry chew.

Probability P ( A ) = 10/20

P ( A ) = 0.5

Hence , the unlikely event is Rolling a 1 on a standard six-sided die, numbered from 1 to 6

Problem: Jessica ordered a pizza. One-half of the pizza had pepperoni only, one-sixth of the pizza had mushrooms, and the rest of the pizza was cheese only. What fraction of the pizza was cheese only?

Answers

Answer:

1/3 of the pizza

Step-by-step explanation:

Number of pizza ordered = 1

pepperoni only part = One-half of the pizza = 1/2 of the pizza

Mushrooms part = one-sixth of the pizza = 1/6 of the pizza

Cheese only part = x

Total pizza = pepperoni only part + Mushrooms part + Cheese only part

1 = 1/2 + 1/6 + x

1 = (3+1) /6 + x

1 = 4/6 + x

1 - 4/6 = x

x = 1 - 2/3

= (3-2) / 3

x = 1/3 of the pizza

Cheese only part = x = 1/3 of the pizza

There are 60 calico cats at the animal shelter if this represents 30% of the cats in the shelter how many total cats are there

Answers

Answer: 200 cats in total

Step-by-step explanation:

60 calico cats represents 30% of the total cat population in the shelter.

That means that if we find 30% of the total number of cats, the number we will get is 60.

Assuming the total is x, representing this in equation form makes it:

x * 30% = 60

x = 60 / 30%

x = 200 cats in total

Power usage is measured in kilowatt-hours, kWh. After 7 a.m., the power usage on a college campus increases at a rate of 21% per hour. Prior to 7 a.m., 15,040 kWh have been used. The university has a daily goal to keep their power usage less than or equal to 100,000 kWh.

Which of the following inequalities can be used to determine the number of hours, t, after 7 a.m. when the power usage on campus will be less than or equal to 100,000?A.
15,040(0.79)t ≤ 100,000
B.
15,040(1.79)t ≤ 100,000
C.
15,040(1.021)t ≤ 100,000
D.
15,040(1.21)t ≤ 100,000

Answers

Answer:

D. 15,040(1.21)t ≤ 100,000

Step-by-step explanation:

The 15,040 is the prior electricity, and it increases by .21 per hour, and you don't want 100,000

To make an equation, use the simple interest formula (same concept)

Total = Amount(1 + rate) time

fill it out

100,000 >= 15,040(1.21)t

This equation is the same as D so D is the answer

How many​ flowers, spaced every 4 ​in., are needed to surround a circular garden with a ​200-ft ​radius? Use 3.14 for π.

Answers

Find the circumference of the circle:

Circumference = 2 x r x pi

Circumference = 2 x 200 x 3.14

Circumference = 1,256 feet.

4 inches/ 12 inches per foot = 0.333 ft.

Divide the circumference by the spacing:

1255/0.333 = 3,768

You will need 3,768 flowers
