Answer is D - square root of 98
Reason
Using Pythagorean theory to first solve for base diagonal with known legs 5 and 3.
a^2 + b^2 = c^2
5^2 + 3^2 = c^2
25 + 9 = c^2
34 = c^2
Take square root of both sides
5.8 = c

Now find the answer for the diagonal
By using the same formula with known legs 5.8 and 8
5.8^2 + 8^2 = c^2
33.6 + 64 = c^2
97.6 = c^2. Round up to 98
Answer is square root of 98

Identify and solve the inequality that represents how many $20 bills, n, you can withdraw from the account without going below t

Alex Ar [27]

Answer:

$100 + 20n \leq 230$

$n \leq 6$

Step-by-step explanation:

Given

$Balance = \$230.00$

$Minimum = \$100$

$Withdrawal = \$20\ each$

Required

Represent using an inequality and solve

Let the number of dollars be represented by n

<em>If 1 withdrawal is $20 bill</em>

<em>n withdrawals would be $20n bills</em>

The total withdrawal and the minimum balance must be less than or equal to the available balance.

So, this gives

$Minimum + Total\ Withdrawal \leq Available\ Balance$

Substitute values for each of these

$100 + 20n \leq 230$

Solving for n

$20n \leq 230 - 100$

$20n \leq 130$

Divide through by 20

$n \leq 6.5$

But n can not be decimal because it represents number of dollar bills , which must always be an integer.

So, we round down the value of n

$n \leq 6$

The students in Mrs. Mandel’s class need to choose two class

sammy [17]

Do you know the Combination Formula? If Not it is (n!)/r!(n - r)!
I think n would equal 6, and r would equal 2. So it would be 6!/2!(4!)
I believe you can do this yourself now that I've given you an equation.
