Step-by-step explanation: Take the highest number minus the lowest number and that his how many numbers are between 12 and 111.

Answer:

370.83%

Step-by-step explanation:

Divide them, and then multiply by a hundred.

Answer:

25 and 30

Step-by-step explanation:

Given the ratio of 2 numbers is 5 : 6 = 5x : 6x ( x is a multiplier ), then

5x + 6x = 55, that is

11x = 55 ( divide both sides by 11 )

x = 5

Thus

5x = 5 × 5 = 25

6x = 6 × 5 = 30

Then the 2 numbers are 25 and 30

“Think-of-a-number” tricks

These tricks come in two types: Think of a number (but don't tell me), do some arithmetic with that number, and I can predict your result. Think of a number, do some arithmetic, tell me your result, and I can instantly say what number you started with.

Step-by-step explanation:

Percentage increase = (279 - 180)/180 x 100% = 55%

this is a topic on percentage. the above question requires a use of a kind of formula if you wish to explore more into this topic you can give me a follow on Instagram (learntionary) I've already posted some notes on this topic and will be doing more on others and also I'll be providing tips on some topics as well!

Answer:

55% increase

Step-by-step explanation:

First I want to say I recommend using sites like Calculator soup, and finding the option "percent increase calculator", for problems like these instead of wasting any points that you could use later on, and Secondly (happy to help), oof and third:

1) subtract the final value minus the starting value

279 - 180= 99

2) Divide that amount by the absolute value of the starting value

99 divided by 180 equals .55

3) Multiply by 100 to get percent increase

changes to 55.00 (final answer 55%)

4) If the percentage is negative, it means there was a decrease and not an increase.

Percentage Increase Formula

Answer:

That means it will take you 1 and 1/3 hour to go a kilometer.

Answer: yes it has gone down 1/5th because the answer would be 27 and that is a lot lower than the other numbers.

Step-by-step explanation:

162 minus 135 = 27

Answer:

3 hours

Step-by-step explanation:

Xavier can paint the average house in 4 hours

This means that in 1 hour, Xavier paints 1/4 of the house

Mohamad can do it in 12 hours

That means in 1 hour, Mohamad paints 1/12 of the house

Hence,

Together the amount of the house they can paint in 1 hour is

1/4 + 1/12

The Least common denominator is 12

(3 × 1 + 1 × 1)/1#

= 3 + 1/12

= 4/12

= 1/3

Together they can paint 1/3 of the house

The number of hours, that it would take to paint a house if they both worked together is

= 1/3 = 1

Cross Multiply

= 3 × 1

= 3 hours

Can you mark me brainliest

hi

You have two points     A ( X;Y)  and B ( X ; Y)

 slope is   :    ( Yb -Ya)   / (Xb -Xa )

(3 - (-13) ) / ( 7 - 9)  =    (3 +13)  /  -2 =   16/-2  =  - 16/2 = -8  

slope is  -8

Answer:

-8

Step-by-step explanation:

The slope formula is as follows:

m = y2 - y1 / x2 - x2

You would first plug in the points into the formula, and this is what you would get:

m = 3 - (-13) / 7 - 9

From there, because of additive inverse, the negative signs would become + signs.

m = 3 + 13 / 7 - 9

You would now add/subtract.

m = 16 / -2

And lastly, you would simplify.

m = 8/-1

8/-1 is the same thing as a slope of -8.

Answer:

The system of inequalities are;

q + w ≤ 20

8w + 10q ≤ 160

Step-by-step explanation:

Let the number of wigs be w and the number of quesadillas be q

Since we have a maximum of 20 packages;

then;

q + w ≤ 20

Let’s now work with the prices

price of w wings is 8 * w =$8w

price of q quesadillas is 10 * q = 10q

The maximum amount to spend is $160

Thus, the addition will be;

8w + 10q ≤ 160
