Two Word Problems :)BTW.. If You Cant Read It, The Numbers Are 56 Out Of 400, And 7 Out Of 50, I Wrote

Answers

Answer 1

4. Yes, Zack is correct.

56 7

----- = -------

400 50

Think about it. If we multiply both the numerator and the denominator of the second fraction above by 8, we get the same fraction as the one on the left.

7 x 8 56

---------- = -------------

50 x 8 400

∴ Yes, Zack is correct.

5.

We must assume that out of 400 of 150, 000 , about 3 coins will have misprint.

So, we can solve now.

150 000 400 ↔ Think, number of coins divided by misprints.

------------- = -----------

x 3

This is called the rule of three.

(150 000 x 3) = 400

450 000 400x

------------- = ------------

400 400

1,125 = x

∴ We can predict that there will be 1, 125 misprints in a year.

Answer:   x = 30

=======================================================

Explanation:

If a regular polygon has n sides, then each interior angle has the measure of

i = 180(n-2)/n

In this case, we have n = 6 sides, so,

i = 180(n-2)/n

i = 180(6-2)/6

i = 120

Each interior angle of a regular hexagon is 120 degrees.

This means the bottom-right angle of the triangle is 120 degrees. The upper-right angle of that triangle is shown to be x degrees. The remaining angle is also x due to the triangle being isosceles (recall that regular hexagons have all sides the same length). Isosceles triangles have congruent base angles, which are opposite the congruent sides.

Use the fact that for any triangle, the three angles always add to 180, and we get...

x+120+x = 180

2x+120 = 180

2x = 180-120

2x = 60

x = 60/2

x = 30

X=30 fine the whole thing first

Answer:

C. 6

Step-by-step explanation:

So it says read less thann 25 books --> that means the numbers are 13,14,14,16,19,21,21,22,23, and 24 --> a total of 10 numbers

Then it says read more than 35 books --> that means the numbers are 37,41,42,43 --> a total of 4 numbers

Now, it says how many more --> that means you subtract 4 by 10 = 10 - 4 = 6

Therefore the answer is 6 more students read less than 25 books than read more than 35 books.

yes ! what grade are you in? this is some difficult math

Calculate the surface area of each figure below. Figures are not drawn to scale.

Answers

i believe it’s 14 because it’s a cube you’d multiply the area to the number of sides and 2 1/3 times 6 is 14
To find the surface area of a cube the formula required is:
6a(squared)

Substitute for “a” which is 2 1/3
Then square 2 1/3
Lastly multiply it by 6!!

So you should get 32.67 (this answer is rounded)

The answer without rounded is 294/9

You should still get the same answer if the fraction is divided.

Hope this helps!!

Simplify the ratio 22:4

Answers

Answer:

2:11

Step-by-step explanation:

Answer:

11 : 2

Step-by-step explanation:

We have the ratio 22:4 and we are asked to simplify it.

Ratios work like fractions, you need to divide both sides by the same number until you reach a number that cannot be divided equally both towards the numerator and denominator unless making it a decimal.

If so, we can divide both of the numbers in this ratio by 2 because they are divisible by that.

22 : 4

22 / 2

4 / 2

11

2

11 : 2

Since both numbers cannot be divided equally without ending in a decimal, therefore, the simplified ratio is 11 : 2
