Which of these quadrilaterals can have two sides with length 8 cm and two sides with length 3 cm? Select all that apply. Rectangle Rhombus Square Parallelogram Trapezoid
Answer: Rectangle
Rhombus
Parallelogram
Step-by-step explanation:
A rectangle has four sides and the opposite sides are equal.
A rhombus is simply a flat shape that has 4 equal straight sides and the sides have equal length.
A square has all the four sides equal.
A parallelogram is a quadrilateral that has two pairs of parallel sides. It should be noted that the opposite sides of the parallelogram have equal length.
A trapezoid doesn't have two sides with equal lengths. Therefore, the correct answer to the question will be:
• Rectangle
• Rhombus
• Parallelogram

En una oficina hay 96 computadores en total. La razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3 : 5. ¿Cuántos computadores de la oficina deben ser reparados en total?
Answer:
36 computadores deben ser reparados.
Step-by-step explanation:
Dado que en una oficina hay 96 computadores en total, y la razón entre los computadores que deben ser reparados y aquellos que se encuentran operativos es 3:5, para determinar cuántos computadores de la oficina deben ser reparados en total se debe realizar el siguiente cálculo:
(96 / (3+5)) x 3 = computadores que deben ser reparados
(96 / 8) x 3 = computadores que deben ser reparados
12 x 3 = computadores que deben ser reparados
36 = X
Por lo tanto, 36 computadores deben ser reparados.
On a test that has a normal distribution, a score of 49 falls three standard deviations below the mean, and a score of 59 falls two standard deviations above the mean. Determine the mean of this test.
The mean of the test that has a normal distribution is 55.
What is the mean of the test?Let's denote the mean of the test by μ, and the standard deviation by σ. We can use the information given to set up a system of two equations:
49 = μ - 3σ equation (1)
59 = μ + 2σ equation (2)
To solve for μ, we can eliminate σ by adding equations (1) and equation (2) to get:
49 + 59 = μ - 3σ + μ + 2σ
Simplifying, we get:
108 = 2μ - σ
We can also solve for σ by subtracting equation (1) from equation (2) to get:
59 - 49 = μ + 2σ - (μ - 3σ)
Simplifying, we get:
10 = 5σ
Therefore, σ = 2.
Substituting this value of σ into the equation we found earlier, we get:
108 = 2μ - σ
108 = 2μ - 2
Solving for μ, we get:
2μ = 108 + 2
2μ = 110
μ = 110/2
μ = 55
Therefore, the mean of the test is 55.

Answer:
I think you need to combine the equations, which would end with 26x - 2, and to solve for x just isolate it by adding to the other side which would look like 26x = 2
Then divide 26 on both sides, 26x/26 = 2/26
You should end with x = 1/13
Calculate the volume of the cylinder
Answer:

Amy and Myra each walked from their houses to the mall. Amy walked one half a mile and Myra walked two-thirds of a mile. How far did the girls walk all together?
in fractions pls help me
Answer:
its c
Step-by-step explanation:
just add 1/2 +2/3 = 1 1/6
Total distance of the girls walk all together is 7/6 of a mile.
Here,
Given that;
Amy and Myra each walked from their houses to the mall.
Amy walked one half a mile and Myra walked two-thirds of a mile.
We have to find the total distance of the girls walk together.
What is Distance?
Distance is the total movement of an object without any regard to direction. We can define distance as to how much ground an object has covered despite its starting or ending point.
Now,
Amy walked one half a mile.
⇒ 1/2
Myra walked two-thirds of a mile.
⇒ 2/3
Hence,
Total distance of the girls when they walk together = [tex]\frac{1}{2} + \frac{2}{3}[/tex]
= [tex]\frac{3+4}{6}[/tex]
= [tex]\frac{7}{6}[/tex]
So, Total distance of the girls walk all together is 7/6 of a mile.

f
is inversely proportional to
√
g
.
When
f
=
12
,
g
=
36
Work out
g
when
f
=
8
Answer:
g = 81.
Step-by-step explanation:
f = k/√g where k is a constant
When f = 12 g = 36, so:
12 = k/√36 = k/6
k = 12*6 = 72.
So the relation is:
f = 72/√g
When f = 8:
8 = 72/√g
8√g = 72
√g = 72/8 = 9
g = 9^2 = 81.
A new LED light bulb uses 10 watts of power. Since
energy
=
power
×
time
, then the energy used for this light bulb can be found my multiplying the power times the time the bulb is lit. If the bulb is lit for one hour, the energy used will be 10 watt*hours or 10 Wh. If three 10 watt bulbs in one room are kept on for 5 hours, how many watt*hours of energy are used?
Parents sometimes yell at their children for leaving the light on in their bedroom when they aren't in the room. If the child's room is lit with two 10 watt bulbs for one extra hour a day for everyday of the year (365), and the cost of energy is $0.068 per kilowatt*hour (kWh), how much money is wasted on lighting that isn't being used, to the nearest cent.
Answer:
150 Wh
I guess the question means, how much money is wasted on lighting in a year ?
$0.50
Step-by-step explanation:
3 × 10W × 5 hours = 150 Wh
2 × 10W × 1 hour × 365 × 0.068 / 1000
divided by 1000, because the price is in kWh (1000 Wh), but the rest of the calculation refers to W. so, we need to bring all factors to the same dimension. the division by 1000 either brings the Wh to kWh, or the price to the price for Wh (instead of kWh). it does not matter which one. just one of these 2 things have to happen here, so that all factors have the same dimension.
=> 20 × 365 × 0.068 / 1000 = 7300 × 0.068 / 1000 =
= 7.3 × 0.068 = $0.50 (rounded from 0.4964)

Elite parking charges cost $15 for the first hour and $7 for each additional hour of parking. Write and equation to represent the cost (C) for parking (t) hours.
Answer: C(t) = 8 + 7t
Step-by-step explanation: 15 for first hour. 15 is constant and every hour after that is counted (t-1)·7, so 15 + 7(t-1) = 15 +7t - 7 = 8 + 7 t .
So when t = 1 C(1) = 15
Elite parking charges cost $15 for the first hour and then $7 for each additional hour then the equation for this will be C = $15 + $7(t).
What is an equation?Equations are mathematical expressions that have two algebras on either side of an equal (=) sign. The expressions on the left and right are shown to be equal to one another, demonstrating this relationship. L.H.S. = R.H.S. (left-hand side = right side) is a fundamental simple equation.
As per the statement mentioned in the question,
Elite parking charges $15 for the first hour which is a constant value.
An additional charge is $7 for every extra hour.
So, the equation according to this is,
C = $15 + $7(t).
Here, C is the total cost and t is the number of hours of car parking, if the number of hours will increase the cost will also increase.

Ellie is running down the street at 10 m/s. She sees a double-tall latte on the road ahead of her and starts sprinting. After 5 seconds have passed, Ellie is running 15 m/s. Assuming she does not change directions, what was Ellie’s acceleration?
Answer:
2m/s²
Step-by-step explanation:
acceleration = change in velocity/time taken
a = v-u/t
Given
v = 15m/s
u = 5m/s
time t = 5secs
Substitute
a = 15 - 5/5
a = 10/5
a = 2m/s²
Hence Ellie’s acceleration is 2m/s²

403(b)
529 plan
health FSA
a tax-deferred retirement savings plan available to employees of some nonprofit
organizations and educational Institutions
a tax-advantaged college savings plan
an employer-offered retirement account that accepts contributions from
employees and employers
a tax-advantaged savings account available through employers to pay for
qualified medical expenses
Answer:
●an employer-offered retirement account that accepts contributions from employees and employers - 401(k)
●a tax-deferred retirement savings plan available to employees of some nonprofit - 403(b)
●a tax-advantaged college savings plan- 529 plan
●a tax-advantaged savings account available through employers to pay for qualified medical expenses- health FSA
Step-by-step explanation:
●401(k): Retirement
A 401(k) is one of the most well-known tools for retirement savings. A 401(k) is an employer-sponsored retirement plan that allows employees to contribute money on a pre-tax basis. Your contributions and earnings are not taxed until you start making withdrawals.
●403(b): Retirement
Like 401(k) accounts, a 403(b) is a form of an employer-sponsored retirement account. If you work for a public school, university, or non-profit organization, you may be eligible for a 403(b) account.
With a 403(b), you make contributions before taxes are taken out of your paycheck. You don’t pay taxes on the contributions .
● ROTH IRA: Retirement
A Roth IRA works differently than a Traditional IRA. Your contributions are not tax-deductible, and you make contributions with after-tax dollars. However, Roth IRAs offer a unique advantage: your earnings and withdrawals are tax-free. Roth IRAs have the same contribution limits as Traditional IRAs.
● 529 Plan: Education
A 529 education savings plan is a tool you can use to save for your child’s college tuition and fees. The money you invest can grow over time, and if the money is withdrawn to pay for qualified educational expenses, earnings are not subject to federal income tax. Depending on your state, your contributions may also be tax-deductible.
While 529 plans do not have contribution limits, contributions toward a 529 plan count as gifts and are subject to gift-tax laws.
● Flexible Spending Accounts: Health
Some employer-offered health insurance plans include flexible spending accounts (FSAs). With an FSA, you make pre-tax contributions into a separate account to use for health expenses. You can use your FSA dollars to purchase prescription and over-the-counter medications, pay your deductibles or coinsurance, and purchase medical supplies.
