Answer: 2 2/5 distance

Step-by-step explanation:

You know 1/4 of an hour you travel of 3/5 of distance, so let’s set an proportion: 1/4 hr = 3/5 of distance, multiply 4 on both sides, and you get 2 2/5 distance. Hope this helps!

PLEASE HELP I WILL GIVE BAINY LIST TO WHOEVER ANSWERS ALL THE QUESTIONS !!!!!

Answer:

1. $97\frac{3}{4}$

2. $3$ x $6\frac{3}{4}$ = $20\frac{1}{4}$

3. $77$ $\frac{1}{2}$

4. Yes (explanation given below)

Step-by-step explanation:

1. Find the area of the wall including the door...

Just multiply the numbers for the width and length.

$11\frac{1}{2}$ x $8\frac{1}{2}$ = $97\frac{3}{4}$

And now, as you can see.

$97\frac{3}{4}$ is our answer for 1.

2. Find the area of the door. (improper fraction)

Again, we just have to multiply, then simplify, and remember to keep it in improper fraction format.

$3$ x $6\frac{3}{4}$ = $20\frac{1}{4}$

so now, we can see that that is the area of the door, but according to the question, we have to leave the answer in the improper fraction format. To turn a mixed number into a improper fraction, we have to multiply the denominator of the fraction with the whole then, add the numerator, the answer that we get is going to be the numerator of the improper fraction and the denominator remains the same.

20 1/4 = 81/4 (improper fraction)

So, 81/4 is our answer for 2.

3. Without door space, give how much wall area there is. (mixed number)

So, as we already know that the door covers up 20 $\frac{1}{4}$ , so all what we have to do is, take the area of the Whole wall and door and subtract it by the door area.

WHOLE wall = 97 $\frac{3}{4}$

Door only = 20 $\frac{1}{4}$

$97\frac{3}{4}-20\frac{1}{4} = 77\frac{1}{2}$

So, hence, the answer for 3. is 77 $\frac{1}{2}$

4. Does Amelia have enough paint? Explain...

Yes, amelia has enough paint for covering the whole intire wall because she has enough paint for a 100 square feet, and the actual surfact area of her wall is JUST 97 3/4 square feet. So, she definitely has enough paint to cover that wall and door.

Thank You! Please mark me brainliest so that I get encouraged to make more great answers like this one!

An investment is currently worth 1.035×108 dollars . Thirty years ago, the investment was worth 2.3×105 dollars. How many ti

nevsk [136]

The correct option is: B. 450

<u><em>Explanation</em></u>

Current value of the investment is $1.035\times 10^8$ dollars and 30 years ago, the value of the investment was $2.3\times 10^5$ dollars.

Suppose, the value of investment today is $n$ times greater than the value of the investment thirty years ago.

So, the equation will be........

$n(2.3\times 10^5)=1.035\times 10^8\\ \\ n= \frac{1.035\times 10^8}{2.3\times 10^5}=0.45\times 10^3 = 450$

Thus, the value of the investment today is 450 times greater than the value of the investment thirty years ago.
