Jeanne makes hair bows to sell at the craft fair. Each bow requires 1.5 yards of ribbon.At the fabric store, ribbon is sold by

Over [174]

1.5 yards of ribbon per bow
84 bows need to be made, so 1.5 x 84 = 126 yards

1 yard = 0.33 feet, so 126/0.33=381.8181 (ans must round up)

So Jeanne will need 382 feet of ribbon

Trig Help please! 50 points!

IgorLugansk [536]

Answer:

Step-by-step explanation:

Remember the mnemonic: SohCahToa, where:

$\sin(\theta)=\text{opposite}/\text{hypotenuse}\\\cos(\theta)=\text{adjacent}/\text{hypotenuse}\\\tan(\theta)=\text{opposite}/\text{adjacent}$

Let's determine our side lengths first.

Note that our angle is A. So, we have to determine the sides with respect to A.

The opposite side to A is 16.

The adjacent side is 12.

And the hypotenuse is 20.

With this, we can find our trig ratios:

Sine:

$\sin(A)=\text{opp}/\text{hyp}$

Substitute 16 for the opposite and 20 for the hypotenuse. This yields:

$\sin(A)=16/20$

Reduce:

$\sin(A)=4/5$

Cosine:

$\cos(A)=\text{adj}/\text{hyp}$

Substitute 12 for the adjacent and 20 for the hypotenuse. This yields:

$\cos(A)=12/20$

Reduce:

$\cos(A)=3/5$

Tangent:

$\tan(A)=\text{opp}/\text{adj}$

Substitute 16 for the opposite and 12 for the adjacent. This yields:

$\tan(A)=16/12$

Reduce:

$\tan(A)=4/3$

So, our answers are:

$\frac{4}{5}, \frac{3}{5}, \text{ and } \frac{4}{3}$

Out of the answer choices, the choice that represents this is C.

So, our correct answer is C.

And we're done!

Step-by-step explanation:

To do this: Agora = 1x+16

Key Club = 4x+4

1x+16=4x+4

1x+12=4x

Write the slope intercept form of an equation for the line that passes through (5,3) and is parallel to x+3y=6

rusak2 [61]

Answer:

y= - $\frac{x}{3}$ +2

I hope this correct and helped! :)

Step-by-step explanation:

Slope intercept: y=mx+b

x+3y=6

Subtract x on both sides

3y=-x+6

Divide by 3 on each side.

y= - $\frac{x}{3}$ +2

What is the measure of angle B? PLEASE HELP

saw5 [17]

Answer: The answer is C, 102 degrees

Step-by-step explanation:

A triangle must add up to 180 degrees, you add 28 and 50, which gives you 78. 180 minus 78 is 102. So the answer is 102 degrees.

Hope this helps!
