Please help asap i need help and explain how do u count this without a ruler

Answers

Answer:

you would take your index finger and your thumb and put them toward the eraser and move your fingers and the answer is 9 or 13 if you needed help with that

Step-by-step explanation:

Answer:

13 cm

Step-by-step explanation:

The good news is that you don't need a ruler!

First, you see that the eraser is approximately 5 cm in length, so you must your mind to mentally picture the eraser beside it. You end up with 10 cm. Then, you see that there is more space left on the stick. You know that another complete eraser will not fill up that space. So, you must ask yourself: What is larger than 9 cm, but smaller than 15 cm? The answer is 13 cm!

For the translation, I believe it would be:
First; a reflection over the Y axis and the new points would be A(4,4) B(2,2) C(2,-1) D(4,1). (The Y value should be the same and the X axis should be the opposite)
Second; It should be moved three units down to get the points that A’ B’ C’ and D’ lie

I *think* they are congruent. I forgot what it exactly means, but they still have the same shape size and have all the same angles.

Hope this helps.

Please show work too! You will get Brainliest!

Answers

Answer:

703.125

Step-by-step explanation:

Working days : 5

Working hours : 3.5 + 4 = 7.5 Hours

Earning in a day = 7.5 * 18.75 = 140.625

Earning in the week (working days only): 140.625 * 5 = 703.125

In the last week Mrs. Rodriguez earned $703.125

How to know how much money did she make for the entire week's work ?

According to the problem,

Mrs. Rodriguez worked 5 days last week. She worked 3.5 hours before and 4 hours after lunch. Mrs. Rodriguez earned $18.75 per hour.

Total hours of work = (3.5 + 4) hours = 7.5 hours in one day

In 5 days she worked (7.5 x 5) hours = 37.5 hours

In the last week Mrs. Rodriguez worked 37.5 hours.

∴ Amount of money she earned = $ (37.5 x 18.75) = $703.125

Relate a vertical line test to understanding functions.
a.
Each horizontal line drawn through the graph will intersect a function in only one location
c.
Each vertical line drawn through the graph will intersect a relation in only one location
b.
Each vertical line drawn through the graph will intersect a function in many locations
d.
Each vertical line drawn through the graph will intersect a function in only one location

Please select the best answer from the choices provided

A
B
C
D

Answers

Answer: Choice D

Each vertical line drawn through the graph will intersect a function in only one location.

This is another way of saying that for any input x, there is exactly one output y. If you had a vertical line cross through a curve at multiple points, then this would mean that x input produces multiple y outputs, and we won't have a function. A function must produce one output whatever the input is (assuming the input is in the domain of course).

I think it’s D hope it helps! 1

What is the cost of making one burrito?

Answers

Answer:

$4.27

Step-by-step explanation:

Answer:

The cost of making one burrito is $2.50

By selling 100 burritos the restaurant would have profits of $550

Step-by-step explanation:

Since the cost of meat is $1.50 and the cost of other ingredients is $1 you add both of these together to get the total cost of making a burrito which is $2.50

In order to calculate profits you subtract 2.5 from 8 (which is 5.5) because it takes $2.5 to make a burrito

To find the total profits of selling 100 burritos you do 5.5 x 100= 550
