What is the area of this parallelogram? ____cm2

Answers

Answer 1

Answer:

Answer:

30.6

Step-by-step explanation:

The area of a parallelogram is base * height.

Base = 6.8

Height = 4.5

6.8 * 4.5 = 30.6

Answer 2

Answer:

Just answering so Adriantan2019 can get brainliest because that was a good answer and I don't remember how to do the area! SORRY! :) Have a great day! :)

I asked this so many times and still no answer answer someone pleaseInstructions In this experiment, you will be using two coins as a simulation for a real-world compound event. Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.

1 What is the theoretical probability that the family has two dogs or two cats? Describe how to use two coins to simulate which two pets the family has.

Flip both coins 50 times and record your data in a table like the one below. Result Frequency Heads,

Heads Heads, 9

Tails Tails,26

Heads Tails,26

Tails 15

Based on your data, what is the experimental probability that the family has two dogs or two cats?
If the family has three pets, what is the theoretical probability that they have three dogs or three cats?

How could you change the simulation to generate data for three pets?

I just need the last questons answered thank you so much

Answers

In order for the simulation to generate data for three pets, you would need three coins.

write three ratios that are equivalent to the one given:the ratio of right of right-handed students to left-handed students is 18:4.

Answers

The three equivalent ratios are 27/6, 45/10, and 36/8.

Given,

The ratio of right-handed students to left-handed students is 18:4.

We need to find three equivalentratios of 18:4.

What is a ratio?

A ratio is denoted by A:B.

If the ratios are equal we called it proportion.

Example:

2/4 = 16/32 = 6/12

2/4 = 1/2

16/32 = 2/4 = 1/2

6/12 = 1/2

2/4, 16/32, and 6/12 are equivalent ratios and they are in proportion.

We have,

18:4

It can be written as:

= 18/4

Reducing it to the smallest term.

= 2 x 9 / 2 x 2

= 9 / 2

So,

We can have,

27/6, 45/10, and 36/8 as our equivalentratios.

27/6 = 3 x 9 / 3 x 2 = 9/2

45/10 = 5 x 9 / 5 x 2 = 9/2

36/8 = 4 x 9 / 4 x 2 = 9/2

Thus the three equivalent ratios are 27/6, 45/10, and 36/8.

The three ratios that is equal to 18:4 are

9 : 2 if you divide 18 and 4 by 2
36 : 8 if you multiply 18 and 4 by 2
54 : 12 if you multiply 18 and 4 by 3

Hope this helps!!

Complete the calculations below to write equivalent fractions, with a common denominator. 4/5 and 5/6

Answers

I think you're saying that you want equivalent fractions for 4/5 and 5/6 ,
and the equivalent fractions should both have the same denominator. OK.

Have you learned "least common denominator" yet ?
Or maybe "least common multiple" ?

It's the smallest number that 5 and 6 both go into with no remainder.

I'm not going to try to explain the whole general method for finding it.
That confuse both of us, you and me.

In this case, I'll just tell you that the smallest common denominator here
is 30 . Now you have to find the two numerators, so that the new
fractions will really be equivalent to the old ones.

-- Write 4/5 as something with a denominator of 30 .

   4/5 = ? / 30 .

What is the '5' multiplied by to get the '30' ?
   It's multiplied by 6 to get 30 .
   So multiply the 4 by the same 6.    The equivalent fraction is 24/30 .

-- Write 5/6 as something with a denominator of 30 .

   5/6 = ? / 30 .

   What is the '6' multiplied by to get the '30' ?
   It's multiplied by 5 to get 30 .
   So multiply the 5 by the same 6.    The equivalent fraction is 25/30 .
