The measure of an angle is 4y. Find the measure of its complement.A) 90 - 4y
B) 90 + 4y
C) 180 - 4y
D) 180 + 4y

Answers

Answer 1
Answer: Complementary angles are angles whose measure add up to 90°.

So, if one angle is 4y, the complementary angle is 90°- 4y. Choice A.

Complementary angles does not necessarily need to share a line or vertex. As long as both angles have a sum of 90°, then, they are complementary angles.

Angles who has a sum of 180° are called supplementary angles.

How does the diagram illustrate the Pythagorean theorem?

Answers

The image illustrates the Pythagorean theorem because adding the areas of the two smaller squares equals the area of the largest square.

What is Pythagoras's theorem?

Pythagoras's theorem states that in a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

As per the given question, the required solution would be as:

The 2nd greatest square's area is 64 units².

Area = l × w

Area = 8 × 8 = 64

the smallest square's area is 36units².

Area = 6 × 6 = 36

the smaller square's area combined is 64 + 36=100units².

the largest square's area is 100units².

Area = 10 × 10 = 100

The area of the largest square (100) units² equals the sum of the areas of the smaller squares (100) units².

Answer:

The diagram illustrates the Pythagorean theorem because if you add the area of the two smaller squares it equals the area of the largest square.

Step-by-step explanation:

the 2nd biggest square's area is 64. (A=lw

                                                             A=8x8

                                                             A=64)

the smallest square's area is 36. (A=lw

                                                      A=6x6

                                                      A=36)

the smaller square's areas combined is 100. (64+36=100)

the largest square's area is 100.  (A=lw

                                                       A=10x10

                                                       A=100)

the largest square's area (100) equals the smaller square's areas combined (100).

An artificial lake is in the shape of a rectangle and has an area of 9/20 square mile. The width of the lake is 1/5 the length of the lake. What are the dimensions of the lake?

Answers

The area is width times length, so you'd divide the area by the width. This is 9/20 divided by 1/5. When dividing fractions, you flip the second number then divide straight across. This would be 9/20 x 5/1. You'd get 45/20, or in mixed number form, 2 and 1/4.

Help FastWhich of the following is a binomial experiment?
Rolling a six-sided number cube 24 times and recording if a 4 comes up
Rolling a six-sided number cube and recording the number until a 4 comes up
Rolling a six-sided number cube and recording the number until an even number comes up
Rolling a six-sided number cube 24 times and recording the number that comes up

Answers

Answer with explanation:

An experiment is said to be binomial, if it has n number of trials,and out of n trials,when each trial is performed Independently, there are only two possible outcomes,one Success and other will be failure.

In option A,  

Number of trials = 24,which is fixed.

Success= getting 4,when a die is rolled.

Failure = Getting ,number other than,4 , that is , 1,2,3,5,6.

So, This is Binomial Experiment.

In Option B,

Number of trials is not fixed.So, This is not Binomial Experiment.

In Option C

Number of trials is not fixed.So, This is not Binomial Experiment.

In Option D

Number of trials = 24

But, there are more than two possible outcomes.So,this is not a Binomial Experiment.

Correct Option : A

The answer on E2020 is A: Rolling a six-sided number cube 24 times and recording if a 4 comes up.

Jenna was 4 4/6 feet tall last year. This year she is 5 2/6 feet tall. How many feet did Jenna grow in the past year

Answers

You want to subtract the heights. 5 2/6-4 4/6=5 1/3-4 2/3=2/3.
You could turn the mixed fractions into improper fractions so 4 4/6 would become 28/6 and 5 2/6 would become 32/6. Then you can subtract 32/6 by 28/6 which would be 4/6 simplified into 2/3
