Answer:
Option C is correct
The wrapping paper is needed to wrap the gift box is, 400 in²
Step-by-step explanation:
Surface area of the prism(S) is given by:
where, l is the length , w is the width and h is the height of the box receptively.
Given that:
A gift box is 14 inches long, 8 inches wide, and 4 inches high
⇒ l = 14 inches, w = 8 inches and h = 4 inches
Substitute these in [1] we have;
Therefore, wrapping paper is needed to wrap the gift box is, 400 in²
Answer:
20%
Step-by-step explanation:
Step 1: Subtract starting value minus the final value (decrease)
Step 2: Divide the decrease by the original number
Step 3: Multiply the result by 100 to get a percent decrease
Therefore, the percent decrease of the price of paper per package is 20%
<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>
Answer:
x =
Step-by-step explanation:
Given
kx - c = 9 ( add c to both sides )
kx = 9 + c ( isolate x by dividing both sides by k )
x =
Answer:
The probability that he picked 2 purpled socks is <u>0.33</u>.
Step-by-step explanation:
Given:
Number of purple socks,
Number of orange socks,
Two socks are picked without replacement.
Now, total number of socks,
Probability of picking the first cap as purple cap is given as:
Since there is no replacement, the number of socks decreases by 1. Also, if the first sock picked is purple, then number of purple socks is also decreased by 1.
Therefore, probability of picking the second cap as purple cap is given as:
Now, probability that both the picked caps are purple is given by their probability product. This gives,
Therefore, the probability that he picked 2 purpled socks is 0.33
