Answer:

Hence, 70 people out of 100 who had attained the previous year

Step-by-step explanation:

If this is completely proportional, you'd make the formula

$ \frac{420}{600} = \frac{x}{100} $

Cross multiply

$42000 = 600x$

Then we just divide by 600

$x = 70$

Answer: Exact Form:

Decimal Form:

0.375

Step-by-step explanation:

Answer:

The answer is 3/8 = 0.375

Step-by-step explanation:

We have

$ \sqrt{ \frac{9}{64} } $

$ = \sqrt{ \frac{ {3}^{2} }{ {8}^{2} } } $

$ = \frac{3}{8} $

$ = 0.375$

Maria’s current car gets 24 miles per gallon. Last year she drove 15,000 miles. Last year gas cost an average of $3.35
solve 1. How much did Maria spend for gas for her car last year?
solve 2. Maria is buying a new car that averages 32 miles per gallon. If she drives the car 15,000 miles in the next year and gas prices stay the same, how much will she spend for gas in the next year?
solve. 3 ) How much money will Maria save in gas costs in the next year by driving her new car as opposed to her old one?
solve 4. What percent decrease in gas costs for one year will Maria realize by driving her new car?

Answers

1) Last year, Maria spent $2093.75. Here's the equation to find that answer:

(a ÷ b) × c

a = 15,000b = 24c = 3.35

(15,000 ÷ 24) × 3.35

2) Same equation. (15,000 ÷ 32) × 3.35. The answer of this equation is 1570.3125, but that rounds to $1570.31.

3) This part represents a simple difference/subtraction problem. Since she spent $2093.75 last year, and will spend $1570.31 with a new car, she will save 523.44.

4) Using percent of change, the percent decrease Maria will realize in one year is 33.333%, or $\frac{1}{3}$.

2.14x - 12.18 = -5.76

Since the inverse operation of subtraction is addition, add 12.18 to both sides.

2.14x=6.42

Now, since the inverse operation of multiplication is division, divide both sides by 2.14

x=3

An appliance store sells an oven for 25% off the original price. The sale price is $251.85, not including tax. What is the price of the oven, not including tax, before the discount is applied. Show your work please I will be marking brainliest.

Answers

Answer:

$352.31

Step-by-step explanation:

Appliance store sold the oven for 25% off original price.

Sale price =$281.8

Price of the oven before the discount was applied is

= 25% /100% x $281.85

= 0.25 x $281.85

= $70.46

The appliance was sold at $70.46 less than the original price

Original price

= $70.46 + $281.85

= $352.31

HOPE THIS HELPS!

Let x be the original price.
0.75x = 251.85
x = 335.8
Therefore, the original price is $335.8.

Lee can type 1 1/3 pages every 15 minutes. How many hours does it take him to type 10 2/3 pages? Complete the rate table to solve the proportion.

pages---> 4/3=32/3
hours---> 1/4 = x

Lee can type 10 2/3 pages in _________ hours.
a. 1 3/4
b. 2
c. 2 1/4
d. 2 1/2

Answers

Answer:

First, we know that:

1 1/3 = 4/3

10 2/3 = 32/3

15 minutes = 0.25 hours

Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.

From the information, we can tell that:

Lee can type:

4/3 pages in 0.25 hours

32/4 pages in x hours

So x should be:

x = (32/4 . 0.25)/4/3 = 2 (hours)

So it takes Lee 2 hours ro type 10 2/3 pages

cassie is placing stickers on a page that is 12 inches long and 8 inches wide the sticker are 3 inches long and 2 inches wide

Answers

Answer:

To find the greatest number of stickers Cassie can place on a page that is 11 inches long and 8 inches wide without them overlapping, we need to use the same approach as before.

Firstly, we need to calculate the maximum number of stickers that can fit along the length of the page, which is now 11 inches. Since each sticker is 3 inches long, we can fit 3 stickers along the length (11 ÷ 3 = 3 with a remainder of 2).

Next, we can calculate the maximum number of stickers that can fit along the width of the page, which is still 8 inches. Since each sticker is 2 inches wide, we can fit 4 stickers along the width (8 ÷ 2 = 4).

To ensure that the stickers do not overlap, we can only use the full row of 3 stickers from the previous calculation. Therefore, we can place 3 stickers along the length and 4 stickers along the width, giving us a maximum of 12 stickers that Cassie can place on the page without them overlapping.

Step-by-step explanation:

Answer:

Step-by-step explanation:

First, find out how much stickers you can put on the long side:

12/3 = 4

Next, find out how much stickers you can put on the wide side:

8/2 = 4

Lastly, calculate them together:

4x4=16

So the answer is 16.
