How many positive integers are factors of 55^3 + 66^3?
Answer:
10
Step-by-step explanation:
55³ + 66³ =
= (5 × 11)³ + (2 × 3 × 11)³
= 5³ × 11³ + 2³ × 3³ × 11³
= 11³(5³ + 2³ × 3³)
= 11³ × 341
= 11³ × 11 × 31
= 11^4 × 31
The factors are:
1, 11, 31, 11², 11³, 11^4, 11 × 31, 11² × 31, 11³ × 31, 11^4 × 31
The factors are:
1, 11, 31, 121, 341, 1331, 3751, 14641, 41261, 453871

Answer:
A.2
Step-by-step explanation:
x² = 16
take the square root of both sides
x = ±4
there are 2 solutions to the equations, those 2 solutions being 4 and -4
just to double check
4² = 4 × 4 = 16

A can is shaped like a cylinder 5.2 cm wide and 2.3 cm tall. find the volume of the nearest tenth. use 3.14 for pie.
Please help me!!
30 points for it!!!!!!!!!!
Answer: 48.8
Step-by-step explanation: The equation for the area of a circle is π*r², since the base of a cylinder is a circle we take the equation of a circle and multiply the height of the cynlinder by using the equation π*r²*h to get the volume of a cylinder. In this case our factors are
π= 3.14
r²= 6.76
h=2.3
3.14*6.76*2.3=48.82072
rounded to the nearest tenth=48.8
Answer: the answer is 48.8

Step-by-step explanation:
add 3 to both sides
subtract 4 from both sides
[tex]\sqrt{x} +4-3=1\\\sqrt{x} +4=4\\\sqrt{x} =0[/tex]
Answer: x=12
√x+4 - 3 = 1
(√x+4 - 3) + 3 = 1 + 3
√x + 4 = 4
(√x+4)^2 = 4^2
√(x+4)^2 = 16
x+ 4 = 16 (cancels out the square root)
(x + 4) + (-4) = 16 + (-4)
x + 4 - 4 = 16 - 4
And then just solve it out
x = 12

Anna took a job that paid $100 the first week she qaa guaranteed a raise of 5% each week how much money will she make in all over 8 weeks round the answer to the nearest cent
Answer:
140.71
Step-by-step explanation:
WEEK 1- 100
WEEK 2- 105
WEEK 3-110.25
WEEK 4-115.7625
WEEK 5-121.550625
WEEK 6-127.62815625
WEEK 7-134.009564063
WEEK 8-140.710042266
By using an exponential equation, we will see that in the first 8 weeks she makes $954.90.
How much will she make in 8 weeks?
We know that the first week she makes $100, and for each week after that, she makes an extra 5%.
Then, the second week she makes:
W(2) = $100*(1 + 5%/100%) = $100*(1.05)
The third week she makes:
W(3) = $100*(1.05)*(1 + 5%/100%) = $100*(1.05)^2
We already can see the exponential pattern, for the N-th week, the salary will be:
W(N) = $100*(1.05)^(N - 1)
Then what she wins in the first 8 weeks is:
W(1) = $100W(2) = $100*1.05 = $105W(3) = $100*(1.05)^2 = $110.25W(4) = $100*(1.05)^3 = $115.75W(5) = $100*(1.05)^4 = $121.55W(6) = $100*(1.05)^5 = $127.63W(7) = $100*(1.05)^6 = $134.01W(8) = $100*(1.05)^7 = $140.71Now we just need to add these 8 values, we will see that the total money that she makes in these 8 weeks is:
M = $954.90

Lacey worked 40 hr. at $18.75 per hour. Find her pay using P = RH.
Answer:
750
Step-by-step explanation:
I multiplied the hours she worked by the amount of payment per hour.
Answer:
$750
Step-by-step explanation:
Since Lacey worked 40 hours with the condition that each hours, Lacey will be paid for $18.75, because they worked 40 hours, therefore:
[tex]\displaystyle \large{P = 18.75+18.75+18.75+...+18.75}[/tex]
From above, you add from first hour pay to 40th hour pay. However, that’d take quite a long time to evaluate:
[tex]\displaystyle \large{\sum_{H=1}^{40} 18.75 = 18.75 \cdot 40}[/tex]
Then evaluate 18.75 * 40 and therefore the solution is $750
For usage of formula:
P = RH for P = pay, H = hour and R = rate (pay per hour)
So if you use the formula, you’d still end up with P = 18.75*40 which is $750

Kerry participated in a fundraiser for the Children's Wish Foundation yesterday. She sold 115 pins for $3 each, 214 ribbons for $4 each, 85 coffee mugs for $7 each, and 347 baseball hats for $9 each. Calculate the average amount Kerry raised per item.
Answer:
$6.46
Step-by-step explanation:
The average per item is the quotient of the total raised and the number of items. The total raised is the sum of the products from multiplying the number of items at a given price by that price.

I need help ASAP or im going to fail
Answer:
45
Step-by-step explanation:
Since it given that her parent and grandmother attend a soccer game. Thus, we can see that there is no students.
Also given that:
Student tickets: $6
Non-Student tickets : $12
Parking : $9
Thus,
Non- Student tickets:$ 12 (Parents and grandmother are not students)
Parking: $9 ( Since they attend a soccer game they need somewhere to park)
Parents = 2 person (Mom and Dad)
Grandmother = 1 person
1 + 2 = 3
Now,
Since Non-student tickets = $12
3 * 12 +9
36 + 9
45
Hence, the family spend $45 to attend the game.

Heather invested $11,600 in an account that pays 5% simple interest. If she invests the money for 6 years, how much will she have?
The total amount in the account after 6 years is $______?
Answer
$15080
Step-by-step explanation:
ok so i havent done these in a while but basically.
First, we need to find out what the 6% is.
[tex]\frac{5}{100} \times \frac{11600}{1}[/tex]
5/100 because it's PERCENT, and well we need to put the 11600 out of 1.
Wich gives us
$580. THen, we multiply that by 6, (6 years). Which gives us
$3480. Now, we add that to the $11600. WHich gives us
$15,080.

Arnold is about to go on a 500-mile car trip. His mechanic recommends that he buy
a special highway engine oil that will save him 50 cents in gas for every 25 miles of the
trip. This new oil, however, will cost $20. Is it worthwhile for Arnold to buy the oil if he
has a coupon for $4 dollars off the price?
500 miles/ 25 = 20 x 0.50 = $10
He will save a total of $10
20-4 = $16
it will cost him $16 for the oil which is more than what he saves in gas so buying the oil is not worth it.
