Damien , Jake , and Makayla shared a bowl of grapes . Damien ate x grapes . Jake ate 1 more than twice the number of grapes that Damien ate . Makayla ate 5 fewer grapes than Damien ate . If there were 6 grapes left , how many grapes were in the bowl ?

Answers

Answer 1

Answer:

There were (4x + 2) grapes in the bowl

Step-by-step explanation:

Here, we are interested in calculating the total number of grapes in the bowl.

We have 3 people sharing the total

Damien are x grapes

Jake ate 1 more than twice what Damien and that is (1 + 2x) grapes

Makayla ate 5 fewer grapes than Damien: So what Makayla ate is (x-5) grapes

And now, we have 6 grapes left.

To find the total number of grapes in the bowl, we need to add up all what they ate plus what is left.

Mathematically, that would be;

x + 1 + 2x + x -5 + 6

= 4x + 2

Answer 2

Answer:

Answer:

Write 400% as the ratio 400/100. To find an equivalent ratio, you know that 400 divided by 20 is 20, so 100 divided by 20 will give you the answer. 100 ÷ 20 = 5. Reza ate 5 grapes yesterday.

A circular playground for a daycare center is to be covered with square tiles that are 9 inches on each side. The circle has a diameter of 12 ft. The tiles are packaged in boxes of 25 tiles. How many boxes of tiles are needed?A. 6 (not A)
B. 8
C. 9
D. 12

Answers

The number of boxes of tiles is 6. The correct option is A.

What is the area of the circle?

The space occupied by any two-dimensional figure in a plane is called the area. The space occupied by the circle in a two-dimensional plane is called as the area of the circle.

Given that a circular playground for a daycare centre is to be covered with square tiles that are 9 inches on each side. The circle has a diameter of 12 ft. The tiles are packaged in boxes of 25 tiles.

The area of the circle is,

A = π x r²

A = π x 6²

A = 113 square ft

The area in square inches is,

A = 113 x 12 = 1356 square inches

The number of tiles will be,

Number = 1356 / 9

Number = 150

The number of boxes,

N = 150 / 25
N = 6 boxes

Therefore, the number of boxes will be 6.

Marco's painting has an area of 320 square inches. If the width of the painting is 16 inches, what is the length of the length of the painted?

Answers

If you would like to know what is the length of the painting, you can calculate this using the following steps:

an area = width * length
320 = 16 * length
length = 320 / 16
length = 20 inches

The correct result would be 20 inches.

Area = length * width320 = l * 16320/16 16/16320/16 = 20Length = 20 inches

Solve each proportion
5/t = t/45

Answers

$45t\cdot \frac { 5 }{ t } =\frac { t }{ 45 } \cdot 45t\n \n 225={ t }^( 2 )\n \n t=\pm \sqrt { 225 } \n \n t=\pm 15$

t = 15 or -15 because you solve proportions by cross multiplying. if you write it out in the following way:

5 t
__= __
t 45

Then, cross multiplying involves multiplying the numerator( number at the top) of one of the fractions with the denominator (number at the bottom) of the other, and setting the two results equal to each other. You get t * t = 5 * 45 and end up with t^2 = 225 or t = (15 or -15)
