Mathematics
2 answers:
Arada [10]3 years ago
6 0

Answer:

60.

Step-by-step explanation:

We are asked to find 19% of 288 by estimate.

First of all, we will round 19% to nearest ten percent that is 20%.

Let us round 288 to nearest hundred.

288\approx 300

Now, we will find 20% of 300 as:

20\%\text{ of }300=300\times \frac{20}{100}

20\%\text{ of }300=3\times 20

20\%\text{ of }300=60

Therefore, our required amount is 60.

there are two sizes of red and blue marbles in a box. Of the big marbles in the box, 45 are red and 3/4 are blue. The fraction o
nikklg [1K]
Big marbles = 45red 3/4 blue
Small marbles = 2/5 red    3/5 blue    24 more small blue mabrles than red marbles
What percentage of the marbles are big marbles

First of all lets working out the missing values: 
Big Marbles, 45 red, 3/4 blue. If 45 red is 1/4, then 135 (45*3) is 3/4.
Big Marbles, 45 red, 135 blue = 180 in total

For the small marbles, we do some logical thinking:
If red is 2/5, and blue is 3/5. And blue has 24 more than red.
That means 24 = 1/5
So in total there are 120 small marbles (24*5)
There are 180 big marbles 
We add these together, 120 + 180 = 300 marbles
180 / 300 = 0.6 = 60%
^ Divide the big marbles by the number of total marbles

60% of the marbles are big marbles

The corner market sells potatoes at a rate of 1/2 dollars per potato.
inn [45]

Answer:

<em>The cost of 15 potatoes is $7.50</em>

Step-by-step explanation:

The potatoes are sold at a rate of $0.5 per potato.

1. Given Amanda can only spend $5 on potatoes at that price, she can buy at most $5 / 0.5 = 10 potatoes.

Amanda can buy at most 10 potatoes

2. Sam wants to buy 15 potatoes at that very same price. The cost of 15 potatoes is:

15 * $0.5 = $7.50

The cost of 15 potatoes is $7.50
