lilavasa [31]

Answer:

Philip has 1 Quarter, 3 Dimes, 5 Nickels, and 2 Pennys.

Step-by-step explanation:

Given that Philip has 11 coins that equal a total of 82 cents, and his coins include at least 1 quarter 1 dime 1 nickel and 1 penny, to determine how many of each coin does he have the following calculation must be performed:

Quarter = 0.25

Dime = 0.10

Nickel = 0.05

Penny = 0.01

0.82 - 0.25 - 0.10 - 0.05 - 0.01 = 0.41

0.41 = 0.10 x 4 + 0.1 (5 coins + 4 previous coins = 9 coins).

0.41 = 0.10 x 2 + 0.05 x 4 + 0.01 (7 coins + 4 previous coins = 11 coins).

0.25 + (3 x 0.1) + (5 x 0.05) + (2 x 0.01) = X

0.25 + 0.30 + 0.25 + 0.02 = X

0.82 = X

Thus, Philip has 1 Quarter, 3 Dimes, 5 Nickels, and 2 Pennys.

Algebra. Find the values of the variable
aleksklad [387]

You are looking at right angles in the problem. Right angles are 90 degrees.

So set up the problem to solve for X using:

90=4x+12

90-12=4x

78=4x

39/2 or 19.5 = x

PLEASE HELP 99 POINTS PLUS BRAINIEST ANSWER.

1. Percent error is | \frac{guess-actual}{actual}|
The guess is 15.5mi, and the actual distance is 14.5 mi.
Percent error is | \frac{15.5-14.5}{14.5}|=0.69=6.9%

2. The cost will be $31.95*(1+0.075) = $34.35
The 1 represents 100% of the original amount of $31.95, and now we add 7.5% (0.075) to the 100%. In other words we multiply $31.95 by 107.5%.

3. His commission will be $165 out of $4125, or $165/$4215 = 0.039 = 3.9%

4. The principal (amount of money you start with) is $12000, and the interest rate is 15% of that.
15% of $1800 = 0.15*$12000 = $1800
