Answer:
The answer is 1825.35
Step-by-step explanation:
Since the first week isn’t included, we only count 4 weeks.
So first, 2000 x 0.03 = 60
(By the way 0.03 is 3%)
2000 - 60 = 1940
Subtracting 2000 by 60 represents the amount of money the aquarium went down in that week.
Then, week 3:
1940 x 0.03 = 58.2
1940 - 58.2 = 1881.8
Now, the last week, week four:
1881.8 x 0.03 = 56.45
1881.8 - 56.45 = 1825.35.
Therefore, 1825.35 after 5 weeks.

the areas of three rectangle is 3:7:8 . if the average area of the three rectangle is 18cm2,find the different between the biggest rectangle and the smallest rectangle .
Answer:
15 sq cm
Step-by-step explanation:
Let 3x = area of 1st rectangle
7x = area of 2nd rectangle
8x = area of 3rd rectangle
(3x + 7x + 8x)/3 = 18
3x + 7x + 8x = 54
18x = 54
x = 3
3x = 3(3) = 9 = area of 1st rectangle (smallest)
8x = 8(3) = 24 = area of 3rd rectangle (biggest)
24 - 9 = 15 sq cm

What is the IQR (interquartile range)?
Minimum value = 5
Q1=7.5
Median = 13
Q3=17
Maximum value = 23
Enter your answer in the box.
Answer:
IQR (interquartile range) = 9.5Step-by-step explanation:
Q¹ = 7.5
Q³ = 17
IQR = Q³ - Q¹
IQR = 17 - 7.5
IQR = 9.5
Alan made $396 for 18 hours of work. At the same rate, how much would he make for 11 hours of work?
Answer:
Step-by-step explanation:
I think it is helpful to set this up as a proportion as it is the easiest way in my opinion.
1st step: 396/18 and x/11
This is the way you set up the proportion.
2nd Step: You would have to multiply 396 and 11 then divide the value by 18.
396x11 = 4,356
4,356/18 = 242
x=242 Dollars
Answer: 242 dollars
Therefore, Alan would make 242$ while working at the same rate for 11 hours.

OMG PLS HELP WITH THIS IM PANICKING OMG I GOT A F IN MATH MY MOM JUST YELLED AT ME IM CRYING PLS HELP WITH THS-
Sorry about that, here's the answers.
1. expanded form
2. regroup
3. place value
4. A, C, D. The strategy I used was place value and regrouping. I chose these by using place value to help me understand how to regroup and what each option would sum to.
5. D. Ten thousands place
Answer:
1. Expanded form
2. Regroup
3. Place value
4. A, C, D,
C is correct because a one is equal to 1.
1 x 4,200 = 4,200. Therefore 4,200 ones is equal to 4,200. D is correct because a ten is equal to 10. 10 x 420 = 4,200. Therefore, 420 tens is equal to 4,200. A is the same as the rest but with hundreds.
5. A
Step-by-step explanation:
1. Expanded form refers to when a number is separated by place values. Like 555,555 being turned into 500,000 + 50,000 + 5,000 + 500 + 50 + 5.
2. Regrouping is separating number by places values to do an equation like subtraction. For example, 5 tens - two ones.
3. Place values refers to a digit in a number like the 1 in 2,134 is in the hundreds place and the 5 in 5,677 is the thousands place.
4. My answer explains it.
5. A is correct as the 2 in 321,705 is 20,000 while the 2 in 32,571 is 2,000. 20,000 is 10 times larger than 2,000. So the answer is 10.
Aaron invested $7,000 in an account paying an interest rate of 3\tfrac{5}{8}3 8 5 % compounded continuously. Mia invested $7,000 in an account paying an interest rate of 3\tfrac{3}{4}3 4 3 % compounded monthly. After 17 years, how much more money would Mia have in her account than Aaron, to the nearest dollar?
Answer:
$265.27
Step-by-step explanation:
Aaron invested $7,000 in an account paying an interest rate of 3 5/8 compounded continuously. Mia invested $7,000 in an account paying an interest rate of 3 3/4% compounded monthly. After 17 years , how much more money would Mia have in her account than aaron, to the nearest dollar?
Aaron:
A = Pe^rt
r = 3 5/8%
r = 3.625/100
r = 0.03625 rate per year
A = Pe^rt
A = 7,000(2.71828)^(0.03625)(17)
= 7,000(2.71828)^0.61625
= 7,000(1.8519693482716)
A = $12,963.79
Mia:
A = P(1 + r/n)^nt
r = 3 3/4%
r = 3.75/100
r = 0.0375 rate per year
A = P(1 + r/n)^nt
A = 7,000(1 + 0.0375/12)^(12)(17)
A = 7,000(1 + 0.003125)^(204)
A = 7,000(1.003125)^204
A = 7,000(1.8898660935607)
A = $13,229.06
Difference between Mia and Aaron account
Mia - Aaron = $13,229.06 - $12,963.79
= $265.27

Don't forget to use the formula: V=43πr3
A 392.5 cm3
B 523.3¯ cm3
C 3,140 cm3
D 4,186.6¯ cm3
Answer: The correct answer is B. 523.3...cm^3
Step-by-step explanation:
4/3*pi*r^3 is the formula
first, divide the diameter by 2 to get the radius, now, you will begin solving.
4/3*5^3*3.14
5*5*5=125
4/3*125*3.14
125*3.14=392.5
4/3*392.5

Find the next two terms in the sequence.
40, 10, –20, –50, . . .
A.
60, 80
B.
–80, –110
C.
–70, –100
D.
–70, –90
Answer:
B.
–80, –110
Step-by-step explanation:
-80 and -110
It is an arithmetic sequence. The difference = -30. It is the difference between each number in the sequence: 10-40=-30
-50-30=-80
-80-30 =-110
-80
First Identify the sequence being made here.
10-40 = -30
-20-10 = -30
-50-(-20) = -30
Therefor this pattern is decreasing by a rate of 30 so to continue this, just subtract 30 from -50.
-50-30 = -80
The next term is -80.

Find the measure of angle A
can you show me how to solve this problem
Answer:
A = 20 degrees
Step-by-step explanation:
Both legs of the triangles are 2x and equal, so we know that the triangle is isoceles. That means both acute angles are equal as well.
In a triangle there are 180 degrees
180 - 140 = 40
40 remainding degrees/ 2 equal angles
A = 20 degrees
Answer:
angle a = 20
Step-by-step explanation:
So like the person above me said
180-140=40
40 divided by 2 is 20

Answer:
Distance between mall and library is 6.32 miles.
Step-by-step explanation:
Coordinates of the door to the library is at (2, 4) and door to the mall is at (8, 4).
Since, distance between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
Distance = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
By this formula,
Distance between (2, 4) and (8, 4) will be,
Distance = [tex]\sqrt{(8-2)^2+(2-4)^2}[/tex]
= [tex]\sqrt{36+4}[/tex]
= [tex]\sqrt{40}[/tex]
= 6.32 miles
