Explain how complex fractions can be used to solve problems involving ratios?

1 answer:

8 0

Complex fractions are numbers in which the numerator and the denominator are both fractions. in this case, to solve the ratio, we can multiply the numerator fraction by the reciprocal of the denominator fraction. Another way is to solve the fraction separately and then divide eventually.

Serjik [45]

The surface area of a cylinder is:

$2 \pi rh+2 \pi r^2$

So fill in the equation and solve:

$2 \pi (8)(11)+2 \pi (8)^2$
$2 \pi 88+2 \pi 64$
$\pi 176+ \pi 128$
$\pi 304$
$3.14*304$
$954.56 cm^2$

Hope this helps!

Help with this math question please

The answer is B x = -4. x= 3

You must factor the equation by find what 2 numbers can multiply to equal -12 and add to equal 1.

-3 and 4 are the two numbers. Now to put it in factor form would be:

(x - 3)(x + 4) = 0

They y also must equal zero.

Since its equals to 0, we must solve for x for the binomial.

x - 3 = 0 ; x = 3

x + 4 = 0 ; x = -4

The answer you get from solving x, is that answer

there are 3 slices of pie left, and the angle measurement is 72 degrees, how many slices was the pie cut in to

Daniel [21]

15; this is because 3 pies make up 72
with this you can make it so that 3x=72
After this you need to find x which is a single pie
so; (3x/3)=(72/3)
x= 24
Since you know a circle is 360 degrees all around the center
You can do 360/24 making it 15 pies.

The price of a shirt is marked down from $12.50 to $10,00. What is the percent decrease of the shirt?

choli [55]

Answer: 20%.

Step-by-step explanation:

Given, The price of a shirt is marked down from $12.50 to $10.00.

Previous price = $12.50

New price = $10.00

Change in price = Previous price - New price

= $12.50 - $10.00

= $2.50

Now, the percent decrease of the shirt = $\dfrac{\text{Change in price}}{\text{Prevoius price}}\times100$

$=\dfrac{2.50}{12.50}\times100\\\\=20\%$

Hence, the percent decrease of the shirt = 20%.
