I filled this box with 84 one-half inch cubes. What is the volume of the box?​
svp [43]

Answer:

10.5 inches cubed

Step-by-step explanation:

The volume is the amount of 1 inch cubes that fills the box. Breaking one cube into 1/2 cubes will requires 8 to fill the same space. Since 84 1/2 inch cubes fit in, then 84/8 1 inch cubes will also fit. This is 10.5.

A fish take contains 16 goldfish and 24 guppies. If you randomly select 2 fish, what is the probability that they are both goldf
Nostrana [21]

The probability of drawing a goldfish on the first draw is 16 / ( 16 + 24 ), or 16/40, or 2/5. Supposing that the first fish drawn is actually a goldfish, then there are 15 goldfish left among 39 fish, and the probability of drawing a goldfish on the 2nd draw is 15/39, or 5/13. The (joint) probability of drawing 2 goldfish on the 1st 2 draws, without replacement, is (5/13)(2/5) = 2/13.

Verify the basic identity. What is the domain of validity?cot theta = cos theta csc thetasee image
mr Goodwill [35]

Solution

Given the function below

cot\theta=\cos\theta csc\theta

Where

csc\theta=\frac{1}{\sin\theta}\begin{gathered} cot\theta=\cos\theta csc\theta \\ cot\theta=\cos\theta\times\frac{1}{\sin} \\ cot\theta=\frac{\cos\theta}{\sin\theta} \end{gathered}

Also recall that the contangent formula is

cot\theta=\frac{\cos\theta}{\sin\theta}

Thus;

\begin{gathered} cot\theta=\cos\theta csc\theta \\ \frac{\cos\theta}{\sin\theta}=\frac{\cos\theta}{\sin\theta} \end{gathered}

From the above deduction,

sinθ is the denominator,

Hence, the domain of validity is defined for the set of real numbers except for sinθ = 0

The standard tip in a restaurant is 15% of the bill before tax. Many people in California find the tip by doubling the sales tax
cricket20 [7]
To answer this you could do a couple things. 1. Actually calculate both tips and then subtract them. Here is the math ( assuming it is $60, not 60% that you mean). a. 0.15 x 60 = $9. b. 0.0825 x 2 x 60=$9.90. c. 9.90-9.00= $0.90 difference.

The other strategy would be to find the difference on the percents and then multiply by $60. a. 8.25%x2=16.5%-15%. Difference of 1.5%. b. 0.015 x $60=$0.90.
