If each slab of butter is one cup, and you want to double a recipe that calls for 1 and 2/3 cups of butter, how many slabs of bu

ycow [4]

Answer:

$1\frac{2}{3}\ slabs$

Step-by-step explanation:

Let

x -----> the number of slabs of butter

y ----> the number of cups of butter

we know that

The ratio is

$\frac{x}{y} =\frac{1}{1}$

$x=y$

That means-----> The number of slabs of butter must be equal to the number of cups of butter

In this problem

we have

$y=1\frac{2}{3}\ cups$

Remember that

$x=y$

The number of slabs of butter needed must be equal to the number of cups of butter

therefore

$x=1\frac{2}{3}\ slabs$

Tyler runs 8 2/3 miles in 4/3 of an hour. How long does it take each of them to run 10 miles?

adelina 88 [10]

Answer:

It takes Tyler 65 minutes to run 10 miles.

Step-by-step explanation:

First you have to figure out what Tyler's mph is, so you divide 8 2/3 by 4/3=6.5. Then you multiply by 10 get how long it takes him to run 10 miles.

(hope this helps!)

The figures are similar. Find the area. The area of △ △ A B C is 15 square cm. The height of △ △ A B C is 5 cm and the height of

aalyn [17]

Answer:

The area of triangle DEF is $282\ cm^{2}$

Step-by-step explanation:

step 1

Find the scale factor

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

To find the scale factor, divide the height of triangle DEF by the height of triangle ABC

Let

z ------> the scale factor

$z=\frac{13}{5}$

step 2

Find the area of triangle DEF

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

Let

z -----> the scale factor

x ----> the area of triangle DEF

y -----> the area of triangle ABC

$z^{2}=\frac{x}{y}$

we have

$z=\frac{13}{5}$

$y=15\ cm^{2}$

substitute and solve for x

$(\frac{13}{5})^{2}=\frac{x}{15}$

$x=(\frac{169}{25})(15)$

$x=282\ cm^{2}$
