Maya is estimating the product of 88 and 12. Which statements are true? Check all that apply.
If she rounds both values to the nearest ten, her estimate will be 800.
If she rounds both values to the nearest ten, her estimate will be 900.
If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000
If she rounds both values to the nearest ten, her estimate will be 1,600.
If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 2,000.

Answers

Answer 1

Answer:

If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000 because if you take 88x12, your answer is 1056. so knowing that the closest answer to 1056 is 1000 not 900.

Hope it helped!

Answer 2

Answer:

If she rounds 88 to the nearest hundred and 12 to the nearest ten, her estimate will be 1,000.

A 78 kg runner exerts a force of 69 N. What is the acceleration of the runner?(use the formula a=F/m)

Answers

Answer:

The answer is 0.88 m/s²

Step-by-step explanation:

To find the acceleration given the mass and force we use the formula

[tex]a = \frac{f}{m} \\ [/tex]

where

a is the acceleration

m is the mass

F is the force

From the question

m = 78 kg

F = 69 N

We have

[tex]a = \frac{69}{78} = \frac{23}{26} \\ = 0.8846153...[/tex]

We have the final answer as

0.88 m/s²

?

Answers

Answer:

u=2

Step-by-step explanation:

8u+ 33 =-7(u-9)

Distribute

8u+ 33 =-7u+63

Add 7u to each side

8u+33+7u = -7u+63+7u

15u+33 = 63

Subtract 33 from each side

15u +33-33 = 63-33

15u = 30

Divide each side by 15

15u/15 = 30/15

u =2

Answer & Step-by-step explanation:

- 22 = -8u + 6(u-7)

-22 = -8u + 6u - 42

8u - 6u = 22 - 42

2u = -20

u = -20/2

how do you solve this equation 19−4c=17

Answers

Answer:  Whatever you do to one side, you do the same operation on the other. The goal is to get the variable alone with a number on the other side.

Here's how:

Step-by-step explanation:

19−4c=17

19 - 19 - 4c = 17 - 19  Subtract 19 from both sides  19-19 =0 Cancels on the left

-4c = 17-19   subtract: 17-19 = -2

-4c = -2

-4c/4 = -2/-4    Divide both sides by -4  

Negatives divided by Negatives have a Positive quotient  -4/-4 =1, Cancels

Find the 6th term

Answers

Let's see what to do...

_________________________________

Step (1)

Look : 16 , 10 , 4 , ...

It is an arithmetic sequence.

So first we have to find the value of the ratio(( d )) .

To do this, we need to subtract each sentence minus the previous sentence.

So we have : 10 - 16 = - 6

_________________________________

Step (2)

To find the nth sentence in an arithmetic sequence, we must use the following equation :

[tex]t(n) = t(1) + (n - 1)d[/tex]

_________________________________

Step (3)

To find the 6th term just need to put the following parameters in the above sequence.

t(1) = 16 ------ n = 6 ------ d = -6

[tex]t(6) = 16 + (6 - 1)( - 6)[/tex]

[tex]t(6) = 16 + (5)( - 6)[/tex]

[tex]t(6) = 16 + ( - 30)[/tex]

[tex]t(6) = 16 - 30[/tex]

[tex]t(6) = - 14[/tex]
