Answer:

Therefore, 448 inches² Wrapping paper is needed to wrap a present.

Step-by-step explanation:

The Present Shape as per dimensions it is CUBOID

Given:

Length = 8 inches

Width = 8 inches

Height = 10 inches

To Find:

Surface Area of Cuboid = ?

( Wrapping paper is needed to wrap a present )

Solution:

By Formula we have

$\textrm{Surface Area of Cuboid}= 2(Length\times Width +Width\times Height + Height\times Length)$

Substituting the given value in above formula we will get

$\textrm{Surface Area of Cuboid}= 2(8\times 8 + 8\times 10 + 10\times 8)\\\\\textrm{Surface Area of Cuboid}= 2(224)\\\\\textrm{Surface Area of Cuboid}= 448\ inches^{2}$

Therefore, 448 inches² Wrapping paper is needed to wrap a present .

If you draw four cards at random from a standard deck of 52 cards, what is the probability that all 4 cards have distinct charac

mezya [45]

There are $\binom{52}4$ ways of drawing a 4-card hand, where

$\dbinom nk = \dfrac{n!}{k!(n-k)!}$

is the so-called binomial coefficient.

There are 13 different card values, of which we want the hand to represent 4 values, so there are $\binom{13}4$ ways of meeting this requirement.

For each card value, there are 4 choices of suit, of which we only pick 1, so there are $\binom41$ ways of picking a card of any given value. We draw 4 cards from the deck, so there are $\binom41^4$ possible hands in which each card has a different value.

Then there are $\binom{13}4 \binom41^4$ total hands in which all 4 cards have distinct values, and the probability of drawing such a hand is

$\dfrac{\dbinom{13}4 \dbinom41^4}{\dbinom{52}4} = \boxed{\dfrac{2816}{4165}} \approx 0.6761$

-20y + 15 = 2 - 16y + 11

shtirl [24]

In order to answer this, we will first need to combine like terms on each side. on the left, you can leave them alone. however on the right, we will need to combine 2 and 11. this is 13. the right side becomes 13-16y. after that, we can add 20y to both sides. that equals 15=13+4y now we can subtract 13 from both sides. 2=4y. then we divide by 4 on both sides to find y. y=.5

Andrea put $52 in the savings account that pays 4% interest how much interest will she earn in one year

Alik [6]

Answer: $2.08

Step-by-step explanation: First multiply $52 by 4% as a decimal or 0.04. Then, multiply that by the number of years.
=52(0.04)(1)

=2.08
