For which value of m is start fraction 4 over 16 end frction equals start fraction m over 24 end fraction a proportion? A. m = 6 B. m = 8 C. m = 12 D. m = 14

Answers

Answer:

A. M=6

Step-by-step explanation:

Basically, this question is asking you to find m if 4/16 = m/24.

First, 4/16 can be simplified to 1/4. This will make it easier to solve.

You now have 1/4 = m/24.

Multiply both sides by 24 to get 24/4 = m.

Simplify to get m = 6.

In the triangle below, ∠Q is a right angle. Which ratio would be equivalent to the ratio of sin∠R?
a) cos∠Q
b) cos∠S
c) sin∠Q
d) sin∠S

Answers

Answer:

b) cos∠S

Step-by-step explanation:

sin ∠R = SQ/SR

This is same as:

cos S

Correct option is b)

cos<Q

Lets do

[tex]\\ \sf\longmapsto sin<R=\dfrac{P}{H}[/tex]

[tex]\\ \sf\longmapsto sin<R=\dfrac{SQ}{SR}[/tex]

Now

[tex]\\ \sf\longmapsto cos<Q=\dfrac{B}{H}[/tex]

[tex]\\ \sf\longmapsto cos<Q=\dfrac{SQ}{SR}[/tex]

Substitute x with 2, and y with 0.

2(2)-0=4

2 multiplied to 2 is 4, then subtracted to 0 would be 4, thus it is correct.

3x-y=6

Substitute x with 2, and y with 0.

3(2)-0=6

3 multiplied to 2 is 6, then 6 subtracted with 0 is 6, thus it is correct.
