Answer:
$50
Step-by-step explanation:
12 x 30 = 360
960 - 360 = 600
600/12 = 50
Answer: $50
Step-by-step explanation:
All 12 of the televisions have extended warranties 12*30=360
Then subtract the amount earned from the total amount paid for extended warranties:
960 - 360 = 600
Now divide 600 by the number of months in a year:
600/12 = $50
The fixed amount Gi earns for each television he sells is $50
In a certain Algebra 2 class of 20 students, 8 of them play basketball and 7 of them play baseball. There are 8 students who play neither sport. What is the probability that a student chosen randomly from the class plays basketball or baseball?
Answer:
3/4
Step-by-step explanation:
add the students who play baceball and basketball together it will be your numerator
the total amount of students will be your denomanator
then simplify
by the way there can not be 23 students in a class that only has 20 kids so this answer may be wrong according to your wording

Steven invests $20,000 in an account earning 3% interest, compounded annually for 10 years. Three years after Stevens's initial investment, Evan invests $10,000 in an account earning 7% interest, compounded annually for 7 years. Given that no additional deposits are made, compare the amount of interest earned after the interest period ends for each account. (round to the nearest dollar) A) Evan earned $820 more in interest in his account than Steven. B) Steven earned $820 more in interest in his account than Evan. C) Evan earned $1,249 more in interest in his account than Steven. D) Steven earned $1,249 more in interest in his account than Evan.
Steven earned $820 more in interest in his account than Evan.
What is compound interest?Interest on interest, or compound interest, is the adding of interest to the principal sum of a loan or deposit. It's the outcome of reinvesting interest rather than paying it out so that interest is received on the principal plus previously collected interest in the next quarter. The compound interest earned is given by the formula,
[tex]A_1 = P(1+\dfrac{r}{100})^n - P[/tex]
In order to compare the two of the given investment, we need to find the interest in each of the investments.
For the investment made by Steven of $20,000 at 3% interest compounded annually for 10 years. The interest that Steven made is,
[tex]A_1 = P(1+\dfrac{r}{100})^n - P\\\\\\A_1 = 20,00(1+0.03)^{10}-20,000\\\\\\A_1 = \$6,878.33[/tex]
For the investment made by Evan of $10,000 at 7% interest compounded annually for 7 years. The interest that Evan made is,
[tex]A_2 = P(1+\dfrac{r}{100})^n - P\\\\\\A_2 = 10,00(1+0.07)^{7}-10,000\\\\\\A_2 = \$6,057.82[/tex]
Now, if we find the difference in the interest earned by the two of the given person.
The difference in the interest earned
= Interest earned by Steven - Interest earned by Evan
= $6878.33 - $6,057.82
= $820.52 ≈ $820
Hence, Steven earned $820 more in interest in his account than Evan.

For the ratio in Problem 1. how many red
chips are in the bucket if there 44 blue
chips in the bucket?
There would be 22 red chips in the bucket containing 66 total chips.
What is an equation?An equation is an expression that shows the relationship between two or more variables and numbers.
Let us assume the ratio of red chips to blue chips is 1:2.
Hence, if there 44 blue chips in the bucket:
(2/3) * total chips = 44
Total chips = 66
Number of red chips = (1/3) * 66 = 22
There would be 22 red chips in the bucket containing 66 total chips.

special parallelograms meet the given conditions? Draw a sketch for
each scenario.
a. Both diagonals have length y and do not intersect at right angles.
b. One diagonal has length x, the other has length y. The diagonals intersect at right
angles.
Answer:
I'm pretty sure,
1. Is a Trapezoid
2. Is a Rhombus
Step-by-step explanation:
Look at a picture of them,
1. A trapezoid has equal length diagonals, but because of the outer legs? if you want to call them that, they're at an angle, same with its vertices, so, the angles at which they bisect are not right angles.
2. A Rhombus, has diagonals that are not the same length, one is longer than the other. Therefore, that solves the first part of the question. And when they bisect, they bisect at right angles because the side lengths of a Rhombus are congruent.

A sock drawer contains 10 white socks, 6 black socks, and 8 blue socks.
If 3 socks are chosen at random, without replacing the first sock, what is the probability of getting first a black sock, then a white sock, then a blue sock?
Thanks!
Answer:
As a fraction: 10/253
As a decimal: 0.0395 (3 sf)
As a percentage: 3.95% (3 sf)
Step-by-step explanation:
white socks = 10black socks = 6blue socks = 8Total number of socks = 24Therefore, the probability of picking a black sock is:
P(black) = 6/24
As the sock is NOT replaced, we now have one less black sock:
white socks = 10black socks = 5blue socks = 8Total number of socks = 23So the probability of picking a white sock:
P(white) = 10/23
As the sock is NOT replaced, we now have one less black sock and one less white sock:
white socks = 9black socks = 5blue socks = 8Total number of socks = 22So the probability of picking a blue sock:
P(blue) = 8/22
Therefore, P(black) and P(white) and P(blue) is:
6/24 x 10/23 x 8/22 = 480/12144 = 10/253 = 0.03952... = 3.95%

4x^2 +12x +44 remainder 161x +84
Step-by-step explanation:
At each step, the quotient term is the ratio of the leading dividend term to the leading divisor term. The first quotient term, for example, is ...
(4x^4)/(x^2) = 4x^2
The quotient term found this way is multiplied by the divisor and subtracted from the dividend. The difference is the new dividend and the process repeats.
You're done when the degree of the dividend is less than the degree of the divisor. This remainder can be expressed as a fraction with the divisor as the denominator.
