280 because 70 times and number has a 0 in the ones place and 28 × 10 is 280. 280 is also a multiple of 42

Seth did. Seth scores 3/12 times and Zak scores 2/10 times. If you find a common denominator like 120, Zak scores 30/120 shots and Zak scores 24/120 shots. As a result Seth scores a greater fraction of shots.

A car salesman had $65,100 in sales. He earned $1,953 in commission. What percent commission did he earn. Explain your answer.

ahrayia [7]

Answer:

1. The percent commission earned is 3%.

2. The loan period is 3.29 years.

Step-by-step explanation:

1. Salesman has $65,100 in sales. He earned $1,953 in commission.

Let the percent commission earn be x%

Therefore, x% of the sales equals $1,953

$\frac{x}{100} of $65,100 = $1,953$

$\frac{x}{100} * 65100 = 1953\\\frac{65100x}{100} = 1953$

We cross multiply

$\frac{65100x}{100} = 1953\\65100x = 1953 * 100\\65100x = 195300$

Divide both side by the coefficient of 'x' (65100)

$\frac{65100x}{65100} = \frac{195300}{65100} \\x = 3$

Therefore, the percent commission earned is 3%

2. Interest (I) = $299 Principal (P) = $1300 Rate (R) = 7%

The formula for finding interest is given as: $I = \frac{PRT}{100}$

Therefore, substituting into the formula, we have:

$299 = \frac{1300 * 7 * T}{100}$

We are finding the time it takes the loan to earn an interest of $299

$299 = \frac{1300 * 7 * T}{100} \\299 = \frac{9100T}{100}$

We cross-multiply:

$299 * 100 = 9100T\\29900 = 9100T$

Divide both side by the coefficient of T (9100)

$\frac{29900}{9100} = \frac{9100T}{9100}\\T = 3.29$

Therefore, the time taken for the loan to earn such interest is approximately 3.29 years

The senate in a certain state is compromised of 58 republicans, 39 democrats, and 3 independents. How many committees can be for

Nutka1998 [239]

Defining C(n,r) as the number of combinations (order does not count) to choose r objects from n, where C(n,r)=n!/(r!(n-r)!)
there are
C(58,3) ways to choose 3 from 58 republicans,
and
C(39,2) ways to choose 2 from 39 democrats.
So the committee has
(C(58,3)*(C(39,2)) variants, or
58!/(3!55!) * 39!/(2!37!)
=30856*741
=22864296

I CAN BE MARKING YOU BRAINLIST. At a bowling alley, 4 out of 13 bowlers bowled a strike during their game. Use this information

Fantom [35]

you can easily solve it by equating the fractions 4/13 and x/91

here, we suppose x as the number of people who can bowl.

4/13=x/91

or, 4/13×91=x (divide 91 by 13)

or, x=4×7

therefore, x=28

easy peesy lemon squeezy ;-)

Ciara brought $240.00 to spend on gigts for her family. She found 8 identical statures at a gift shop. She had $72 leftover. how

suter [353]

Statues+72=240
minus 72 both sides
statues=168
168=8statutes
assuming they cost the same
divide both sides by 8
21=1statue

each costs $21
