A cookie costs $4/7

Step-by-step explanation:

Let's write an eqution in which X represents the cost of a cookie

14x=8

Now divide both sides by 14

[tex]x=\frac{8}{14}[/tex]

Now simplify by 2

Answer:

10 units

Step-by-step explanation:

Area of a triangle is [tex]\frac{h*b}{2}[/tex]= Area

where h is the height, and b is the base

We can substitute these values into the area equation and get:

[tex]\frac{x*10}{2} = 50[/tex]

Multiply both sides by 2:

x * 10 = 100

Divide both sides by 10:

x = 10

Find the scale factor for the dilation shown.

Answers

The scale factor is 4.

First you need to find the length and height of the squares.

Bigger square:
Length = 20
Height = 16

Small square:
Length = 5
Height = 4

Then take the heights and lengths and divide the bigger numbers (lengths in this case) by the smaller numbers (heights in this case)
*This is using inverse operations. Diving to get what to multiply, since scale factor is multiplying.

bigger shape LENGTH divided by smaller shape LENGTH:
20 units / 5 units = 4

bigger shape HEIGHT divided by smaller shape HEIGHT:
16 units / 4 units = 4

There’s your answer!

Also you didn’t really have to do lengths AND heights, only one, because you already knew both shapes were similar.

if you didn’t know:
the “/ “ symbol means divide






scale factor is 4 since 16/4 is 4

The mean monthly rainfall is ___inches.

Answers

Answer:

The mean monthly rainfall is 3.245 inches.

Step-by-step explanation:

The first step in answering this question is to add all of the months together. This gives us; 38.94.

The second step is to divide the added months by 12 because there are 12 months, and 12 numbers that we added together.

This gives us 3.245.

So, the answer is going to be The mean monthly rainfall is 3.245 inches.

Have a good day and good luck!

The mean monthly rainfall is 3.245 inches.

What is Mean?

Mean of a set of data is defined as the average of all the values. It gives the exact middle point of the data set.

Given is a table which shows the monthly rainfall at a measuring station.

Mean of a set of data = Sum of the data vales / Total number of values.

Here,

Total number of data points = 12

Sum of the data points = 2.22 + 1.51 + 1.86 + 2.06 + 3.48 + 4.57 + 3.27 + 5.40 + 5.45 + 4.34 + 2.64 + 2.14

= 38.94

Mean = 38.94 / 12 = 3.245 inches

Hence the mean monthly rainfall is 3.245 inches.

A straight line has an angle of 180 degrees in total.

This means that we have to subtract 35 from 180.

This gives us 145.

So, the missing angle is going to be 145 degrees.

*also, 1, 4, 5, and 8 are the same angle.

Sorry I couldn't help you with there other ones.

Sponsors:

5s + 10 = 200

You need to get rid of 10 first, you do this by subtracting it by 10, you also subtract 10 to 200

5s = 190

Now you need to get rid of 5 that is attached to the variable, you must divide 5 since it is multiplying, also dividing 5 to 190

s = 38

So it would be 38 sponsors



Comic books:

4c + 6 ≤ 20

Take away 6 by subtracting, also subtracting 6 to 20

4c ≤ 14

You then have to divide 4 to the variable, also dividing 4 to 14

c ≤ 3.5

Now since you can’t get half of a comic book, the greatest amount of comic books he can buy is 3.

3 comic books



Value of x:

3x + 1 = 10

Take away 1 by subtracting 1, also subtracting 1 to 10

3x = 9

Divide 3 to the variable, dividing 3 to 9 as well

x = 3



Value of y:

4y + 6 ≥ 18

Subtract 6 to 6 and 18

4y ≥ 12

Divide 4 to both sides

y ≥ 3 or y is greater than or equal to 3 (in case you can’t see the symbol)
