Well not all because ratios is basically the meaning of fractions so every time you have a problem always cross out the word ratios and put fractions because that will help you and then you tell us is equivalent to your answer such as 8/10 as a ratio and 1/9 as a ratio then you would have to put them across and tell them from each

First you have to figure out the GCF (Greatest Common Factor) of 8 and 10. When you figure that out, the GCF is 2. So then, you would divide 2 by 8 and 10, then you should get the answer which is 4/5.

one orange and one apple cost 1.05, two oranges and three apples cost $2.75, how much do two apples cost?
Nimfa-mama [501]
If you would like to know how much do two apples cost, you can calculate this using the following steps:

o ... the cost of one orange
a ... the cost of one apple

1 * o + 1 * a = $1.05
2 * o + 3 * a = $2.75
_______________
o + a = 1.05 ... o = 1.05 - a
2 * o + 3 * a = 2.75
2 * (1.05 - a) + 3 * a = 2.75
2.1 - 2 * a + 3 * a = 2.75
a = 2.75 - 2.1
a = $0.65

o = 1.05 - a = 1.05 - 0.65 = $0.4

2 * a = 2 * 0.65 = $1.3

The correct result would be: Two apples cost $1.3.

Answer:

A. 16.55

Step-by-step explanation:

What we know is the angle of 38° and the hypotenuse is 21. Before we find x (side b), we have to find side a first. TO find that multiply the sine of 38 by 21.

21 * sin(38)

<em>sin(38) calculates to 0.615661475.</em>

21 * 0.615661475

<em>Multiply 21 by 0.615661475</em>

side a = 12.928890975

Now to find x. Use this to find x: √21² - 12.928890975²

√21² - 12.928890975²

<em>Square both numbers</em>

√441 - 167.156221843

<em>Subtract 167.156221843 from 441</em>

√273.843778157

<em>Find the square root of 273.843778157</em>

x ≈ 16.548225831

x ≈ 16.55, so the answer is A.
