I’m sorry I really need to answer questions

I NEED HELP PLZ!!!!!!!!!!

Answers

Answer:

1/25

Step-by-step explanation:

Since it only contains 1 unknown, given that r = 0, what you need to do is to substitute r=0 into the expression

= (5(0) + 1/5)^2

= (1/5)^2

=1/25

1/25
anything multiplied by 0 is 0
so 1/5 is left
5 square is 25 because 5x5 is 25
keep the numerator
so it 1/25

Evaluate the expression for the given value.

7m−6, when m=8

Answers

Well, if m=8, then we need to replace m with 8. 7 is being multiplied by m, or in this case, 8. Then we'll subtract the product with 6.

7x8 is 56. Now we subtract 56 with 6.

56-6=50

The answer to 7m-6 is 50.

Find the area of the shaded region. Round your answer to the nearest tenth. 9 m 20 9 m area aboutm? pls explain how.
​

Answers

Answer:

The area of the shaded region is 17.4 square meters.

Step-by-step explanation:

Since the shaded region in the center equals the remainders of a circle, the area of a square equals its side squared, and the area of a circle equals π times the radius squared, for To determine the area of the shaded region, the following calculations should be performed:

(9 ^ 2) - (π x (9/2) ^ 2) = X

81 - (π x 4.5 ^ 2) = X

81 - (3.141 x 4.5 ^ 2) = X

81 - 3.141 x 20.25 = X

81 - 63.6 = X

17.4 = X

Thus, the area of the shaded region is 17.4 square meters.

Select all the expressions that are equivalent to 9 + 7x – 3y. 9 + 7x + 3y 9 – 7x – 3y 9 – 7x + 3y 9 + 7x + (–3y) 9 – (–7)x – 3y

The answer is c, when he combined 0.96 and 0.75 they are not like terms. The 0.75 has a y attached to it

Answer:

The answer is C.

Step-by-step explanation:

Everything that Dominic was doing was correct up until step number 4. He added 1.5 and 0.75y. He shouldn't have done that because those numbers do not have like terms. He should have combined 1.5 and -0.96 which would give him 0.54. Leaving us with the actual answer being 0.54 + 0.75y.

also if you dont mind giving me brainliest im trying to rank up, im 1 away. only if u dont mind

Answer:

I think the answer is B

Step-by-step explanation:

40% of 3000 = 1200 and it makes sense because 1500 is half and 40% should be a little lower than that. If the first week is 3000 people, you basically add 1200 x 2 to get 2400, but that answer is not on here, so I just think to round it to 2880 so I guess B.

What is Prime Factorization?

Prime factorization is the method of writing a number as the product of the prime factors.

For example 8 can be written as 8 = 2 × 2 × 2

The expression in the left is a multiplied form and that on the right is the prime factorized form.

1) 30abc

30 = 2 × 15 = 2 × 3 × 5

30abc = 2 × 3 × 5 × a × b × c

2) 45abr

45 = 3 × 15 = 3 × 3 × 5

45abr = 3 × 3 × 5 × a × b × r

3) 25ab

25 = 5 × 5

25ab = 5 × 5 × a × b

4) 2rs

2rs = 2 × r × s

5) 18rst

18 = 2 × 9 = 2 × 3 × 3

18rst = 2 × 3 × 3 × r × s × t

Hence the matching expressions are found.
