Dave measures his calculator using erasers and paperclips. It is about 2 erasers long. Which is true?

Temka [501]

Answer:

Step-by-step explanation:

In the US, the most common eraser that is sold are the regular Pink Press erasers. These, as shown in the image below, are roughly 2.2 inches long. The most commonly used paper clip size is about 1.375 inches long. Assuming that these are the items that Dave is using to measure, then we can calculate the size of the calculator which is 2 erasers long...

2.2 + 2.2 = 4.4 inches long

The calculator is roughly 4.4 inches long, we can also divide this number by the length of the paper clip to find out how many paper clips make up the calculators length

4.4 / 1.375 = 3.2 paper clips

The coordinates of the top of a tree are (-3,8), and an acorn is attached to the tree at (-1,5). If we know that the acorn lies

Charra [1.4K]

Let's say that the coordinates of the squirrel are: (x, y)

Since the coordinates of the acorn is halfway, between the tree and the squirrel, that means the acorn is the midpoint.

To work out the midpoint you do:

(sum of x-coordinates) divided by 2, (sum of y coordinates) divided by 2.

We can use this to form an equation .

So the sum of the x coordinates of the tree and the squirrel = -1 :

x-coordinates of the squirrel:

$\frac{-3+x}{2}=-1$ <em>(now solve for x)</em>

$-3+x = -2$

$x=1$

y-coordinates:

$\frac{8+y}{2}=5$ <em>(now solve for y)</em>

$8+y=10$

$y = 2$

So the coordinates of the squirrel are: (1, 2)

A charity collected $40 for each mile Carlos ran in a race. If the charity received $400, which equation could you use to find o

mrs_skeptik [129]

Are there choices listed? If not, then we can take the information given and translate it to an equation as follows: 40m = 400. Solve for m by dividing both sides by 40 and find that Carlos ran 10 miles.
