Marianne buys 16 bags of potting soil which come in 5/8 pound bags. This equals to 10 pounds of potting soil. Her father calls a
Ann [662]

Answer:

5 bags

Step-by-step explanation:

Given Marianne buys 16 bags of potting soil which come in 5/8 pound bags

The above provides 10pounds of potting soil already

Now her father says he needs 13 pounds So Marianne should get an extra of 13 - 10 =3 pounds of potting soil

We know that 1 bag contains 5/8 pounds of potting soil

x bags contain 3 pounds of potting soil

On cross multiplication we get

\frac{5x}{8}=3

x = \frac{24}{5}

since x is an integer x = 5 bags  

Note that an extra amount of soil will be remained unused

The length of the hypotenuse of a right triangle is 14.5 meters. The length of one of the legs is 8.7 meters. What is the length
GenaCL600 [577]

Answer:

b=11.6m

Step-by-step explanation:

If this is a right triangle;

a^2+b^2=c^2

A and B are both LEGS, while C is the HYPOTENUSE

(8.7^2)+b^2=(14.5^2)

b^2=(14.5^2)-(8.7^2)

b^2=134.56

b=plus or minus 11.6

Because length can't be negative, it's +11.6

How do you multiply -5 that has an exponent of 4 but no parenthesis with 4? Please explain
muminat
A negative sign in front of any expression, is in effect a factor of -1, so -7 for example is really the same as saying -1 * 7, because the -1 is multiplying it right in front of it, therefore

\bf -5^4\implies -1\cdot 5^4\implies -1\cdot 625\implies -625
\\\\\\
\textit{as opposed to }(-5)^4\implies (-1\cdot 5)^4\implies (-1)^4\cdot 5^4
\\\\\\
(-1\cdot -1\cdot -1\cdot -1)(5\cdot 5\cdot 5\cdot 5)\implies 1\cdot 625\implies 625

The radius of a circle is 6 miles. what is the length of a 135° arc? 135° r=6 mi
PSYCHO15rus [73]
This is the formula to determine the length of arc
length of arc = angle/360° × circumference

First we should find the circle circumference
c = 2 × π × r
c = 2 × 3.14 × 6
c = 37.68 miles

Second find the length of arc
length of arc = angle/360 × circumference
length of arc = 135/360 × 37.68
length of arc = 3/8 × 37.68
length of arc = (3 × 37.68)/8
length of arc = 113.04/8
length of arc = 14.13

The length of arc is 14.13 miles
