Giraffes are herbivores,or plant eaters. A giraffe can eat up to 75 pounds of leaves each day. Write and evaluate an expression
n200080 [17]

Answer:

2625 pounds of leaves

Step-by-step explanation:

First, multiply 75 pounds by 7 days, AKA 75 pounds x Week

The answer to that is 525 pounds in a week.

The question asks to find how many pounds of leaves 5 giraffes can eat in a week.

So multiply 525 pounds by 5 giraffes, and you get 2625 pounds of leaves.

For ΔABC, which one is equivalent to sin(A)?<br><br> cos(B)<br> sin(B)<br> cos(C)<br> tan(C)
krek1111 [17]

Answer:

cos(C)

Step-by-step explanation:

Recall that the sine ratio is opposite over hypotenuse.

\sin(A)  =  \frac{BC}{AC}

Also the cosine ratio is adjacent over hypotenuse.

\cos(C)  =  \frac{BC}{AC}

The tangent ratio does not come close because it doesn't involve the Hypotenuse.

\therefore \sin(A)=\cos(C)

topjm [15]

Answer: rate of train A = 120 km/h

rate of train B = 101 km/h

Step-by-step explanation:

Let x = the speed of train A

Let y = the speed of train B

One train travels 19 km/h slower than the other. Let train B be the slower train. Therefore,

x = y + 19 - - - - - - - - - -1

Recall

Speed = distance/time

Distance = speed × time

If they meet in 3 hours, it means that train A has travelled a distance of

x × 3 = 3x km

And train B has travelled a distance of y × 3 = 3y km

Train A and Train B were 663 kilometers apart when they left their respective destinations. They left at the same time and travelled towards each other. This means that if they meet in 3hours time, they must have covered a total of 663 km. Therefore,

3x + 3y = 663 - - - - - - - - - 2

Substituting x = y + 19 into equation 2, it becomes

3(y + 19) + 3y = 663

3y + 57 + 3y = 663

6y + 57 = 663

6y = 663 - 57 = 606

y = 606/6 = 101 km/h

x = y + 19 = 101 + 19

x = 120 km/h
