Answer:
Sonja invested for 5 years.
Step-by-step explanation:
First you have to find how much money she gets in one year.
To do this you would have to multiply 15,000 and 2.8.
15,000 x 2.8 = 42000
You move the decimal 2 spaces forward since there are 3 zeros in 15,000 and one decimal place in 2.8.
This gives you 420.
To find how many years it takes for her to make $2100 you have to divide
2,100/420.
This gives you 5, which means that she invested for 5 years.

Convert 9432000 Milliliters to Liters. Show ALL work and don't forgot the units.
Answer: 9,432 L
To convert 9,432,000, divide by 1,000. Let's explain before we divide.
Look at the zeros in 9,432,000, then look at 1,000. What do they have in common? Zeros. Both numbers have 3 zeros. But what would happen if we divide it by 1,000? Let's figure it out now.
1. Divide 9,432,000 by 1,000.
9,432,000 ÷ 1,000 = 9,432Notice how the zeros were gone when we divided it by 1,000, because we're reducing it by 1,000.
Hence, 9,432 L is the answer.

at the aquarium the dolphins are fed 7 buckets of fish each day the penguins are fed 1/2 as much as the dolphins how many buckets of fish are the penguins fat each day?
Answer:
At the aquarium, the dolphins are fed seven buckets of fish each day. The penguins are fed half as much as the dolphins therefore the three and a half buckets of fish each day.
Step-by-step explanation:
First, the dolphins have 7 buckets of fish a day and the penguins have half.
Second, find the numbers in the problem and x out the useless information.
Third, divide the 7 by 2 (the reason behind dividing by 2 is to get the half of 7)
For which equation is y = 7 a solution?

At this weekend’s football game, 20 out of the first 50 people who entered the field were not wearing hats. If this sample is representative of the 300 people attending the game, about how many of them will probably NOT be wearing hats? Show all work and justify your answer.
Answer:
180 People will wear Hats
Step-by-step explanation:
If there are 30 people that wear hats out of 50 we extrapolate that data meaning we just multiply both till we get the disired number of 300, so 50x6 = 300, so 30x6= 180
Please help. You will get some points.
Answer:
1) x: small #; y: large #
4y = 7x
x + y = 22
----------------
-7x + 4y = 0
x + y = 22
---multiply the second equation by -4------
-7x + 4y = 0
-4x - 4y = -88
----solve------
-11x = -88
x = 8
---substitute with any of the equation above i chose the very first one------
4y = 7(8)
4y = 56
y = 14
x = 8; y = 14
2) x = small #; y = large #
y - x = 15
5x = y - 9
----after rearranging, solve-----
-x + y = 15
5x - y = -9
-4x = 6
x = -1.5
--------substitute--------
-(-1.5) + y = 15
1.5 + y = 15
y = 13.5
x = -1.5; y = 13.5
3) x = lemon cream; y = fudge cookie
3x + 2y = 400
2x + 3y = 425
----multiply the first equation by -2, multiply the second equation by 3------
-6x - 4y = -800
6x + 9y = 1275
----solve------
5y = 475
y = 95
--------substitute--------
3x + 2(95) = 400
3x + 190 = 400
3x = 210
x = 70
x = 70; y = 95

Engineers are digging a 3200-foot-long tunnel at a constant rate. After 5 months, the engineers still need to dig 1700 feet to finish the project. How much time does it take to complete the tunnel from start to finish?
Will the engineers have enough time if the project was started in December 2020 and the deadline to finish the project was in August 2021? Please explain your answer for yes or no.
Hint:
y=mx+b (slope-intercept form)
x=time
y=distance
b=3200
Start & Finish: ??
Total length=3200ft
Left over=1700ft after 5 months of digging
help/
Answer:
Part A answer: 10 2/3 months
Part B answer: No
Step-by-step explanation:
Using what we gathered from the word problem, and the hint, we know that y = distance, x = time, and b = 3200.
3200 is the total number of ft meant for the hole to be dug. If we've been digging for 5 months, and we have 1700 ft yet to be dug, then after 5 months we have dug (3200 - 1700 =) 1500 ft in 5 months.
-1500 ft/5 months = 300 ft/month
-Digging the final 1700 ft will take 5 2/3 months
^ Using this information, we know that the total number of months it takes to dig the entirety of the tunnel is 10 2/3
In the second part of the problem, we're asked to determine whether or not a deadline of August 2021 was enough time to complete the 10 2/3 month-long project if the digging began in December of 2020.
If said project commenced in December 2020, and the deadline was August 2021, then there would be 1, 2, 3, 4, 5, 6, 7, 8... Roughly 8 1/2 months to complete the tunnel. 10 2/3 months is > (greater than) 8 1/2 months. So, no. That start-to-finish deadline would not be enough time.
Good luck!!

Which shape has a greater perimeter?
Answer: Shape B, which is the thin and long rectangle.
Step-by-step explanation:
Shape A:
4 + 4 + 8 + 8
4+4 = 8
8 + 8 = 16
16 + 8 = 24
Shape A has a perimeter of 24.
Shape B:
2 + 2 + 11 + 11
2 + 2 = 4
11 + 11 = 22
22 + 4 = 26
Shape B has a perimeter of 26.
