Sinα=h/L  where h=height, L=string length...

h=Lsinα  so

h(25°)=50sin25≈21.1ft

h(45°)=50sin45≈35.4ft

Myra asked Annabelle to buy her some perfume while she was in France. Annabelle paid 200 euros for it. Myra wants to pay Annabel
serious [3.7K]

Answer:

286

Step-by-step explanation:

Given : Myra asked Annabelle to buy her some perfume while she was in France. Annabelle paid 200 euros for it. Myra wants to pay Annabelle back in U.S. dollars.

To Find:  If the foreign exchange rate between the U.S. dollar and the euro is 1:0.7, how much should Myra pay Annabelle?

Solution:

Since Annabelle paid 200 euros

And Myra wants to pay Annabelle back in U.S. dollars.

Let Myra paid amount to Annabelle in U.S. dollar be x

We are also given that  the U.S. dollar and the euro is 1:0.7

⇒\frac{1}{0.7}=\frac{x}{200}

⇒\frac{1*200}{0.7}=x

⇒\frac{200}{0.7}=x

⇒285.7=x

⇒285.7≈286

Thus Myra should pay $286 to Annabelle

Which shows the pre-image of triangle X'Y'Z' before the figure was rotated 90° about the origin?
Nadusha1986 [10]

Answer: The last option.

Step-by-step explanation:

1. By definiton, the rotation rule 90° about the origin is:

(x,y)⇒(-y,x)

2. You know that the coordinates of triangle X'Y'Z' are the following:

X'(-2,2)

Y'(0,6)

Z'(1,1)

3. Now, when you apply the rule, you obtain that the coordianates of the pre-image are the following:

X(2,2)

Y(6,0)

Z(1,-1)

Therefore, the answer is the last option.

Amie works 6 hours each Saturday and 4 hours each Monday. She also makes $20 a week as a dog walker. She makes a total of $130 e
Harman [31]
I feel like the answer is 

10h = 110 

although it's so simple that I'm not even sure it would be considered an equation. 

I got the answer because she works, in total, 10 hours a week. She makes $130 a week, but since $20 comes from the dog walking, you have to do 130 minus 20 which is 110. That's what I did anyway.
