Answer:

20 cups

Step-by-step explanation:

If Zack fills two bird feeders, and each holds 2 1/2 cups of seed, that means that combined they will hold 5 cups of bird seed. I cup can be divided into fourths (or 1/4), this means that for every cup of bird seed Zack will need four scoops.

Here is an equation to show the answer:

5 cups × 4 (the number of scoops in a cup) = 20 scoops needed to fill both both bird feeders.

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)

Using a t-distribution calculator, the p-value is of 0.052, hence the range that contains the p-value is an interval between a number less than 0.05 and a number greater than 0.05.

<h3>How to find the p-value of the t-distribution?</h3>

To find the p-value of the t-distribution, three information, which are the inputs on the calculator are needed:

  • The test statistic.
  • The number of degrees of freedom.
  • The tail of the test.

In this problem, we have that:

  • The test statistic is of t = -1.788.
  • The number of degrees of freedom is of 10.
  • We are testing if the mean is less than a value, hence we have a left-tailed test.

Hence, using a calculator, it is found that the p-value is of 0.052, hence the range that contains the p-value is an interval between a number less than 0.05 and a number greater than 0.05.

Katie feeds her cat, Elmer, 2/3 of a cup of food each day. She buys a bag of cat food that contains 18 cups of dry
Natasha2012 [34]

Answer:

27

Step-by-step explanation:

Set up a proportion.

1 day / (2/3 cup) = x/ 18 cups            Cross Multiply

1 day * 18 cups = 2/3 cup * x            Multiply both sides by 3

1 day * 18 cups * 3 = 2x

54 day cups = 2x cups                    Divide by 2

54 day cups/2 cups = x

27 days (The cups cancel)
