Alba worked for 6 hr and 45 min at $10.90 per hour. What numbers could she use to estimate how much money she earned? Estimate the amount she earned and state whether you think the exact amount is a little more or a little less than your estimate

Answers

Answer:

Step-by-step explanation:

If we're going by estimation, then you can do 11 and 7 hours, meaning that she would make 77 for the 7 hours but the exact answer would be a bit less than the estimation

10.9 times 6.75 is 73.58 roughly. so 3 dollars and 42 cents off

Answer:

1. She could use 7 hours and 11 dollars per hour.

2. $77 (7x11)

3 I'd say my estimate is a little more than the exact amount because I did 6.75 (6.75 because 45 minutes is 75% of a hour) x 10.90 and got 73.575.

36 > 9x

-We divide by 9, NOT 9x. The reason we only divide by 9 is because we are trying to cancel out and get X by itself

Tara can type 180 words in 4 minutes. At this rate, how many words would you expect her to type in 10 minutes?

Answers

Answer:

450 words in 10 minutes

Step-by-step explanation:

To set this up you need to put it like this:

[tex]\frac{180}{4}[/tex] = [tex]\frac{x}{10}[/tex]

From here, you need to cross multiply, which will get you to: 180(10) = 4x

Multiply 180 and 10: 1,800

The equation will now be: 1,800 = 4x

Now, divide both sides by 4: 450 = x

The required word that tara would type in 10 minutes is 450 words.

Given that,
Tara can type 180 words in 4 minutes. At this rate,
To determine how many words would you expect her to type in 10 minutes.

What is the Ratio?

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The rate of typing = 180 / 4 = 45 word per minute
Now a number of words typed in 10 minutes,

= 10 * 45
= 450 words per minute,

Thus, the required word that tara would type in 10 minutes is 450 words.
