Peter walked 8,900 feet from home to school.

Peter waled 8900 feet. How many miles is it?

Well, it's surely at least one mile! 8900 is bigger than 5280. And how much more than one mile? let's subtract 5280 from 8900:

8900-5280=3620.
now, this is less than another mile: so it's more than 1 but less than 2 miles: only options 3) and 4) are possible. $\frac{3620}{5280}= \frac{362}{528}= \frac{181}{264}= 0.685$

so the exact answer is 1.685 and an approximation is 1.7 (because from digit 5 up we round up: 1.64 would be rounded down to 1.6)- the correct answer is 4)!!!

how much is 3600 feet?

A pizza dough recipe calls for 6 1/2 cups of flour. The recipe makes 37 1/2 ounces of dough. How many ounces of dough does 1 cup

NemiM [27]

Answer:

$n = 5\frac{10}{13}$

Step-by-step explanation:

Given

$Call = 6\frac{1}{2}$ cups

$Recipe = 37\frac{1}{2}$ ounce

Required

Number of ounces per cup (n)

To do this, we simply divide the Recipe by the call

So, we have:

$n = \frac{Recipe}{Call}$

$n = 37\frac{1}{2} \div 6\frac{1}{2}$

Express as improper fraction

$n = \frac{75}{2} \div \frac{13}{2}$

Rewrite as:

$n = \frac{75}{2} * \frac{2}{13}$

$n = \frac{75}{13}$

$n = 5\frac{10}{13}$

Steps for graphing -x^2-4x-3

sdas [7]

Answer:

Step-by-step explanation:

There are several ways to do this. The first, which I personally think is the quickest way without having to do too much math or rearranging the equation is to simply pick random points for x and solve for y.

For instance, you might try -2 for x.

- ( - 2)^2 - 4 ( - 2) - 3

= - 4 + 8 - 3

= 1

So one of your points would be (-2, 1)

Then you might choose, say, -3 for x. And after that, -1 for x. If you want to graph even more points after those (the more points, the more accurate your graph), choose -4 and 0 for x. Simply put it into the equation and find y. Then graph.
