Kevin can travel 22 and a half miles in one third hour what is his average speed in miles per hour

Answers

Answer 1

Answer: If it's 1/3 of an hour then we multiply it by 3 so 22.5 x 3 is 67.5
Answer: 67.5 m/h

Answer 2

Answer: His average speed is 67 1/2 miles per hour. 22.5 in each 1/3 of an hour. So, multiply that by 3 and get 67 1/2 miles in each whole hour.

So,

$√(75) - 4 √(8) - 3 √(32)$

Simplify the radicals.
$√(25) * √(3) - 4 * √(4) * √(2) - 3 * √(16) * √(2)$
$5 * √(3) - 4 * 2 * √(2) - 3 * 4 * √(2)$
$5√(3) - 8 * √(2) - 12 * √(2)$
$5√(3) - 8√(2) - 12√(2)$
$5√(3) - 20√(2)$

A pile of sand has a weight of 90kg.The same is put into a small bag, a medium bag and a large bag in the ratio of 2:3:7.Work out the weight of sand in each bag

Answers

Remark

This requires some sort of constant that each of the ratio members is multiplied by.

Call the constant x

Equation

2x + 3x + 7x = 90 Add the left hand side

Solution

12x = 90 Divide by 13

x = 90 /12

x = 7,5

Answer

2x = 2 * 7.5

2x = 15

3x = 22.5

7x = 52.5

Sum = 90 as it should be

A basketball player has already scored 56 points of the game the team record for points in a game is 72 which equation would allow you to find how many more points to play needs to tie the record

Answers

Answer:

The equation is:

$x+56=72$

Where x is the amount of points needed to tie the record

Step-by-step explanation:

In order to write the equation, we must have to understand the paragraph to find the known facts, the information that we want to find (unknown data) and the relation between them

Known facts:

Player scored points: 56
Team record points: 72

Unknown data:

How many more points the player needs to tie the record?

This unknown data is named as x (the variable to find)

In order to find the relation between known facts and unknown data, we analyze the paragraph:

According to the text, x is the amount of point that the player have to add to his current score (56) to tie the team record (72).

This analysis can be summarized in this sentence: "x plus 56 points must be equal to76 points"

Finally the equation is:

$x+56=72$

think this may be wrong but i think that it is 72-56=
the reason that i think its wrong is that you have nothing after the equils exept for the answer

A bag contains 99 red marbles and 99 blue marbles. Taking two marbles out of the bag, you: • put a red marble in the bag if the two marbles you drew are the same color (both red or both
blue), and
• put a blue marble in the bag if the two marbles you drew are different colors.
Repeat this step (reducing the number of marbles in the bag by one each time) until only one
marble is left in the bag. What is the color of that marble?

Answers

The final marble left in the bag will be red.

Let, analyze the process step by step:

Initially, the bag contains 99 red marbles and 99 blue marbles.

When you take two marbles out of the bag, there are two possibilities: either you get two red marbles or two blue marbles, or you get one red and one blue marble.

a. If you get two marbles of the same color (both red or both blue), you put a red marble in the bag.

b. If you get one red and one blue marble, you put a blue marble in the bag.

After putting a marble back in the bag, you have one less marble in the bag.

You repeat this process, reducing the number of marbles in the bag by one each time, until only one marble is left in the bag.

Now, let's think about the outcomes at each step:

If the bag contains an odd number of marbles (99 red + 99 blue = 198), the final marble will be red because at each step, you are adding a red marble back to the bag.

If the bag contains an even number of marbles (e.g., 100 red + 100 blue = 200), the final marble will be blue because at each step, you are adding a blue marble back to the bag.

In this case, the bag contains 99 red marbles and 99 blue marbles, which is an odd number (198 marbles).

Therefore, the final marble left in the bag will be red.
