To find out if it's a function, check if any of the y values repeat. If they don't, it's a function. :)

Answer:

1. Well, to cross multiply them you multiply the numerator in the first fraction times the denominator in the second fraction, then you write that number down. ... The reason we cross multiply fractions is to compare them. Cross multiplying fractions tells us if two fractions are equal or which one is greater.

2. Cross multiplying fractions to find a missing numerator or denominator for equivalent fractions works because it is a shortcut for rearranging to isolate the variable.

Answer:

Paulo = 3m - 5

Step-by-step explanation:

m = number of quarters Marie has

The number of quarters Paulo has is 3 times 5 fewer than the number of quarters Marie has

3 times number of quarters Marie has = 3 * m

= 3m

5 fewer than the number of quarters Marie has

3m - 5

Paulo = 3m - 5

Answer:

SinA=3/5

CosA=4/5

TanA=3/4

Step-by-step explanation:

first we have to find what side length bc is using the Pythagorean triple formula a^2+b^2=c^2 or c^2-b^2=a^2

20^2-16^2=144 the square root of 144 is 12 so side length bc=12

so sin is opposite/hypotenuse

the opposite of angle a is 12 and the hypotenuse is 20 so sinA is 12/20 or 3/5

cos is adjacent/hypotenuse

the adjacent of angle a is 16 and the hypotenuse is 20 so cosA is 16/20 or 4/5

tan is the opposite/adjacent

the opposite of angle a is 12 and the adjacent is 16 so tanA is 12/16 or 3/4

Step-by-step explanation

Answer:

Model B has 6 shaded sections

Step-by-step explanation:

The question is not complete. The complete question should be in the form:

Victor has 2 fraction models. Each is divided into equal sized sections the models are shaded to represent the same fraction. Model A is divided into 6 sections and 3 sections are shaded. Model B is divided into 12 sections. What do you know about the number of sections shaded in Model B? Explain your answer.

Solution:

The fraction modeled by model A is given by the ratio of shaded sections to  the total number of sections.

That is Fraction of model A = number of shaded sections / total number of sections.

Hence:

Fraction of model A = 3 / 6

Since model B and Model A are equivalent, the number of shaded sections in Model A is given by:

number of shaded sections in model B/ total number of sections in model B =  Fraction of model A

number of shaded sections in model B / 12 = 3 / 6

number of shaded sections in model B = 12 * 3/6

number of shaded sections in model B = 6

16 + 16 + 16 = 16 x 3

16 x 3 = 48

16 + 16 = 32

32 + 16 = 48

Answer: x = -2

[tex]\frac{n^{10} }{n^{12} } =(n^{x})^{1} \\\\<=>\frac{1}{n^{2} }=n^{x}\\\\<=>n^{-2}=n^{x}[/tex]

to make the equation true => x = - 2

$21

Step-by-step explanation:

Given data

Principal= $20

Rate = 5%

time= 1 year

Required

The final amount A

Applying the simple interest formula

A= P(1+rt)

substitute

A=20(1+0.05*1)

A=20(1.05)

A=20*1.05

A=$21

Hence she will earn $21
