On the way home from her friend's house Sandy skateboards 30% of the way, walks 1/2 of the way, and then skips the rest of the w

netineya [11]

Answer:

0.2

Step-by-step explanation:

Convert the walking to percent

$\frac{1}{2} \times 100 = 50$

Add both skateboarding and walking

$30\% + 50\%\\\\= 30 + 50\\\\= 80$

Now, subtract that from a whole percent

$100 - 80 = 20\\\\20\%$

Convert it to a decimal

$20\% = \frac{20}{100} \\\\=20 \div 100\\\\= 0.2$

Therefore, in decimal, 0.2 is the number that shows the portion of the distance Sandy skips.

Diego wants to find 4 1/5 - 7/10 .. Explain why he must rename 4 1/5 in order to do the subtraction?

nevsk [136]

Answer:

The result is 3 1/2 and this is the explanation why Diego must convert 4 1/5 from mixed number to improper fraction.

Step-by-step explanation:

These are the steps Diego should follow to find 4 1/5 - 7/10:

Step 1: Convert all mixed numbers into improper fractions.

4 1/5 = 21/5 - 7/10

Step 2: Find a common denominator between the improper fractions. When necessary, create equivalent fractions.

21/5 = 42/10 - 7/10

Step 3: Add or subtract the numerators and keep the denominator the same.

42 - 7 = 35/10

Step 4: If the answer is an improper form, reduce the fraction into a mixed number.

35/10 = 3 5/10 = 3 1/2

The result is 3 1/2 and this is the explanation why Diego must convert 4 1/5 from mixed number to improper fraction.

The speed of an elevator varies inversely with the weight it carries. If the elevator rises at 10 feet per second when it carrie

777dan777 [17]

Answer:

$8\frac{ft}{sec}$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form $y*x=k$ or $y=k/x$

Let

x-----> the speed of the elevator

y----> the weight it carries

so

$y*x=k$

Find the constant k

For x=10 ft/sec, y=400 lb

substitute

$k=10*400=4,000$

The equation is

$y*x=4,000$

Find the speed for y=500 lb

substitute in the equation

$500*x=4,000$

$x=4,000/500=8\frac{ft}{sec}$

12 dollars for 3 paper back books and 28 dollars for 7 paper back books are they equivalent please explain

kow [346]

If you have 12 dollars and you buy 3 paper back books, they each cost the same amount. So you would divide 12 dollars among 3 books to get the same answer for all of them. 12 divided by 3 equals the answer.

Then if you have 28 dollars and you buy 7 paper back books, they all cost the same amount. So that would be 28 divided by 7, equals the same answer.
