Answer:
34
Step-by-step explanation:
$575-$150= $425
So $425 is how much she needs bc she already gets $150 each week so subtract it from the $575. then do
$425/$12.50=(hours)34) so she needs to work 34 hours this week to get 575$
A triangle has one leg of 24 inches and one leg of 10 inches. For the triangle to be a right triangle, what must be the length of the hypotenuse
Answer: 26 inches
Step-by-step explanation:
The hypoteneuse is the longest side in a triangle. From the question, we are already informed that a triangle has one leg of 24 inches and one leg of 10 inches.
To calculate the hypotenuse, we add the square of both legs together which are the opposite and adjacent and then find the square root. This will be
hypotenuse² = 24² + 10²
hypotenuse² = 576 + 100
hypotenuse² = 676
hypotenuse = ✓676
hypotenuse = 26
The hypothenuse is 26 inches

A boat travels 452 km in 17 hours (with a constant speed). How far can it travel in 9 hours (with the same speed)?
Answer:
so first we have to find km per hour
so lets divide 452/17=26.5882352941
so it travels 26.6 km per hour so lets mulitply for the 9 hours
26.6*9=239.4
it can travel 239.4 km in 9 hours

4. You put $420 into a savings account with an interest rate of 8% compounded annually which earns $33.60 over a period of time. How long was the period of time?
(how to find compound interest time)
Answer: 1 year
Step-by-step explanation:
[tex]\mathrm{Compound \ Interest \ Formula}\\$$\begin{aligned}&A=p\left(1+\frac{r}{n}\right)^{n t} \\&A=420+33.60=\$ 453.60 \\&p=\$ 420 \\&r=8 \% \\&n=1\end{aligned}$$[/tex]
[tex]\mathrm{Solving \ for \ t:}[/tex]
[tex]$$\begin{gathered}453.60=420\left(1+\frac{8}{100}\right)^{1 . t} \\453.60=420\left(\frac{108}{100}\right)^{t} \\\frac{453.60}{420}=\left(\frac{108}{100}\right)^{t} \\1.08=(1.08)^{t}\end{gathered}[/tex]
[tex]\mathrm{Taking \ log \ of \ both \ sides}\\\log 1.08=\log (1.08)^{t}$ \\\log 1.28=t \log (1.08)$ \\1=t$ \\$t=1$\\[/tex]
Therefore, the period of time taken to earn $33.60 was 1 year
Formula for the surface area of a cylinder, SA = 2ar2 + 2arh. Solve for h.
Answer:
[tex]\displaystyle h = \frac{A-2\pi r^2}{2\pi r}[/tex]
Step-by-step explanation:
Recall that the surface area A for a cylinder is given by:
[tex]\displaystyle A=2\pi r^2+2\pi rh[/tex]
And we want to solve for the height h.
First, subtract [tex]2\pi r^2[/tex] from both sides. This yields:
[tex]2\pi rh= A-2\pi r^2[/tex]
Now, we can dvide both sides by [tex]2\pi r[/tex]. This yields:
[tex]\displaystyle h = \frac{A-2\pi r^2}{2\pi r}[/tex]
And we're done!

Angelo, age 40, is comparing the premium for a $125,000 whole life insurance policy he may take now and the premium for the same policy taken out at age 45. the annual life insurance premium (per $1000 of face value) for a 40-year-old male is 22.60 and for a 45-year-old male is 27.75. what would be the difference in total premium costs over 20 years for this policy at the two age levels? a. $69,375 b. $11,725 c. $12,875 d. $644
The difference in total premium costs over 20 years at the two age levels is $12875.
What is face value?Face value is a term used to describe the nominal value of a security, as stated by its issuer.
Let us consider the entire scenario for a 40-year old male.
Annual life insurance premium per 1000 of face value = $22.60
So, the annual life insurance premium for a $125,000 whole life insurance policy = 125000/1000 * 22.60 = $2825.
For 20 years the premium will be = 2825*20 = $56500
Let us consider the entire scenario for a 45-year old male.
Annual life insurance premium per 1000 of face value = $27.75
So, the annual life insurance premium for a $125,000 whole life insurance policy = 125000/1000 * 27.75 = $3468.75
For 20 years the premium will be = 3468.75*20 = $69375
The difference in total premium costs over 20 years = 69375-56500 The difference in total premium costs over 20 years = $12875
Therefore, The difference in total premium costs over 20 years at the two age levels is $12875.

Write the equation, in standard form, of the line passing through (0,-8) with a slope of -1/2
Answer:
The answer is
[tex] \huge \boxed{y = - \frac{1}{2} x - 8 }[/tex]
Step-by-step explanation:
To find an equation of a line given the slope and a point we use the formula
[tex]y - y_1 = m(x - x_1)[/tex]
where
m is the slope
( x1 , y1) is the point
From the question the point is (0,-8) and slope - 1/2
We have
[tex]y + 8 = - \frac{1}{2} (x - 0) \\ y + 8 = - \frac{1}{2} x \\ y = - \frac{1}{2}x - 8[/tex]
We have the final answer as
[tex]y = - \frac{1}{2} x - 8 \\ [/tex]

type the dimensions of a different shaped box that has the same volume
Step by Step Explanation:
120ft³ = 3ft × 4ft × 10ft
120ft³ = 1ft × 1ft × 120ft
120ft³ = 2ft × 2ft × 30ft
120ft³ = 5ft × 3ft × 8ft

Taking fractions or mixed numbers as dimensions, you can give infinitely many such shapes with a volume of 120ft³.
Melisande collected 14 bottles on Saturday and 9 bottles on Sunday for recycling. On Monday, she took all the bottles to the recycling center, where they paid her a certain amount, b, for each bottle. However, she had to pay the recycling center a one-time service fee of $0.25. If she left there with $3.20 for the bottles, what is the value of b?
Answer: The value of b is $0.15.
Step-by-step explanation:
Total bottles co0llected = 14+9 =23
Payment for each bottle = b
Total payment she will get = 23b
One -time service fee = $0.25
She has left = $3.20
According to the question,
23b - 0.25 = 3.20
⇒23b = 3.20+0.25
⇒23b = 3.45
⇒b = 0.15 [divide both sides by 23]
Cost of each bottle = $ 0.15
hence, the value of b is $0.15.
Answer:
B. $0.15

A company currently uses Brand A lightbulbs, which have a mean life of 1,000 hours. A salesperson marketing Brand B, a new brand of bulb, contacts the company. The company will switch to the new brand of bulb only if there is convincing evidence that the mean life of Brand B is greater than 1,000 hours. Which of the following hypotheses should the company test?
A. H0: The mean life of Brand B is 1,000 hours.
H1: The mean life of Brand B is more than 1,000 hours
B. H0: The mean life of Brand B is 1,000 hours.
H1: The mean life of Brand B is less than 1,000 hours
C. H0: The mean life of Brand A is 1,000 hours.
H1: The mean life of Brand A is more than 1,000 hours
D. H0: The mean life of Brand A is 1,000 hours.
H1: The mean life of Brand A is less than 1,000 hours
E. H0: The mean life of Brand A is equal to the mean life of Brand B bulbs
H1: The mean life of Brand A is not equal to the mean life of Brand B bulbs
The hypotheses of the company are:
H0: The mean life of Brand A is 1000 hoursH1: The mean life of Brand B is more than 1000 hoursHow to determine the hypothesesThe hypotheses consist of the null and the alternate hypotheses
The null hypothesis is always represented by the equal to "=" sign.
So, the null hypothesis is:
H0: The mean life of Brand A is 1000 hours
From the question, we understand that the evidence is to show that the mean life is greater than Brand B.
So, the alternate hypothesis is:
H1: The mean life of Brand B is more than 1000 hours
