A sphere has a volume of approximately 24,416.64 cubic inches (using 3.14 for ).
The diameter of the sphere is ___ inches.
Answer:
diameter = 36 in.
Step-by-step explanation:
V = 4π r^3/3
24416.64 = (4(3.14) r^3)/3
73249.92 = 12.56 r^3
r^3 = 5832
r = cube root of 5832 = 18
diameter = 36 in.
Kayla owns a food truck that sells tacos and burritos. She sells each taco for $3 and each burrito for $7.25. Yesterday Kayla made a total of $595 in revenue from all burrito and taco sales and there were twice as many burritos sold as there were tacos sold. Write a system of equations that could be used to determine the number of tacos sold and the number of burritos sold. Define the variables that you use to write the system.
Last Wednesday, students could choose ham or turkey sandwiches for lunch. The cafeteria made 64 sandwiches in all, 16 of which were turkey. What percentage of the sandwiches were turkey sandwiches?
Answer:Percentage of the sandwiches which were turkey=25%
Step-by-step explanation:
Number of sandwiches in all(ham and turkey)= 64
Number of turkey sandwiches =16
Percentage of the sandwiches which were turkey=16/64 x 100
=0.25 x 100
=25%
16. A radioactive isotope has a half-life of 13 hours. Find the amount of the isotope left from a 400-milligram
sample after 65 hours. If necessary, round your answer to the nearest thousandth.
a. 25 mg
c. 0.049 mg
b. 7.692 mg
d. 12.5 mg
Please help. I only see answers for 52 hours
Answer:
Without the math: 65 hours is 5 half-lives
13 hrs = 1/2
26 hrs = 1/4
39 hrs = 1/8
65 hrs = 1/32
(1/2)^5 = 1/32
400 mg / 32 = 12.5 mg that is, after 5 half-lives
A parallelogram with a height of 2x+3 has an area listed below. What is the length of the base of the parallelogram? 2x^2+13x+15
Answer:
x+5
Step-by-step explanation:
I thought what 2 numbers if multiplied made 15
also 2x+3 already has a 3
so I'm guessing 3 and 5
then I put them next to each other
(2x+3) ( +5)
I put a x in the second parenthesis as a guess because the area had a 2x^2 in it . that could only happen with 2x * x
so (2x+3) (x+5)

Compare investing $1500 at 9% compounded monthly for 11 years with investing $1500 at 14% compounded monthly for 11 years.
Answer:
Final amount after 11 years = $4021.97
Step-by-step explanation:
We will use the formula to get the final amount after t years,
Final amount = [tex]a(1+\frac{r}{n})^{nt}[/tex]
here a = Initial amount
r = Rate of interest
n = Number of compounding in a year
For Initial amount 'a' = $1500
r = 9%
t = 11 years
n = 12 [Compounded monthly]
F = [tex]1500(1+\frac{9}{12})^{12\times 11}[/tex]
= $4021.97

Answer:
[tex]x=96[/tex]
Step-by-step explanation:
[tex]360=x+\left(x+90\right)+\left(x-18\right)[/tex]
Step 1: Simplify both sides of the equation.
[tex]360=x+x+90+x-18[/tex]
[tex]360=(x+x+x)+(90+-18)[/tex] (Combine Like Terms)
[tex]360=3x+72[/tex]
Step 2: Flip the equation.
[tex]3x+72=360[/tex]
Step 3: Subtract 72 from both sides.
[tex]3x+72-72=360-72[/tex]
[tex]3x=288[/tex]
Step 4: Divide both sides by 3.
[tex]\frac{3x}{3}=\frac{28}{3}[/tex]
[tex]x=96[/tex]
Hope this helped! :)

The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?
Answer:
Base = 18 inches
Height = 54 inches
Step-by-step explanation:
The height of a parallelogram is three times its base. If the area is 972 square inches, what is the base and height?
The area of a parallelogram is given as:
Base × Height
Height = h = 3b
Area = 972 square inches
We substitute
972 = b × 3b
972 = 3b²
Divide both sides by 3.
b² = 972/3
b² = 324
b = √324
b = 18 inches
Solving for h
h = 3b
h = 3 × 18
h = 54 inches
Therefore,
Base = 18 inches
Height = 54 inches

Answer:
area = 73.37 cm²
Step-by-step explanation:
area of circle:
A = π5² = 78.5 cm²
area of 80° segment:
(80/360)(78.5) = 17.44 cm²
area of isosceles triangle w/ 5 cm legs and 80° angle:
sin 40° = b/5
0.6428 = b/5
b = 3.214
base = 2(3.21) = 6.43 (we only figured for one-half of the base)
cos 40° = h/5
0.7660 = h/5
height = 3.83
A = 1/2(6.43)(3.83) = 12.31 cm²
area of unshaded part:
17.44 - 12.31 = 5.13 cm²
area of total shaded part:
78.5 - 5.13 = 73.37 cm²

Step-by-step explanation:
Ian is borrowing $1000 from his parents to buy a notebook computer. He plans to pay them back at the rate of $60
per month. Ken is borrowing $600 from his parents to purchase a snowboard. He plans to pay his parents back at
the rate of $20 per month. a) Write an equation that can be used to determine after how many months the boys will owe the same amount.
b) Determine algebraically and state in how many months the two boys will owe the same amount. State the
amount they will owe at this time.
c) Ian claims that he will have his loan paid off 6 months after he and Ken owe the same amount. Determine and
state if Ian is correct. Explain your reasoning.
A = 10 months
B = First part, the two equations:
Ian: y = 1000 - 60x, where x is the number of months and y is the remaining balance owed.
Ken: y = 600 - 20x.
They will be equal at 1000 - 60x = 600 - 20x
Second part: Solve the equation. Note, if you're equation is incorrect, solve it anyway because you will still get some credit!
1000 - 60x = 600 - 20x
1000 = 600 + 40x
400 = 40x
x = 10 months
y = 600 - 20(10) = 600 - 200 = $400 still owed.
C =
Solve Ian's equation for y = 0, when no money is owed.
1000 - 60x = 0
1000 = 60x
x = 16.66666.... or 17 months.
Ian will not be paid off 6 months after he and Ken owe the same amount. He will still owe money.
Alternatively, six months after 10 is 16 months,
and y = 1000 - 60(16) = 1000 - 960 = 40. He will still owe $40 at 16 months, so he is not paid off.

Step-by-step explanation:
Amy spent $90 at the store. She spent 1/3 of her money on food, 1/6 of her money on school supplies, and 1/9 of her money on soda. How much did she spend on school supplies?
Given:
Amy spent $90 at the store.
She spent [tex]\dfrac{1}{3}[/tex] of her money on food, [tex]\dfrac{1}{6}[/tex] of her money on school supplies, and [tex]\dfrac{1}{9}[/tex] of her money on soda.
To find:
How much did she spend on school supplies?
Solution:
According to the given information, Amy spend [tex]\dfrac{1}{6}[/tex] of her money on school supplies.
Amy spent $90 at the store. So,
Money spend on school supplies = [tex]\dfrac{1}{6}\times 90[/tex]
= [tex]15[/tex]
Therefore, Amy spend $15 on school supplies.

Answer:
15.70
Step-by-step explanation:
2×3.14×10(90÷360)=15.70
The length of the arc is 15,7 km
ExplainForm :
[tex] =2 \times \pi \times {r} \times \frac{ \alpha \degree}{360 \degree} \\ [/tex]

Solve :
[tex] = 2 \times \pi \times r \times \frac{ \alpha \degree}{360 \degree} \\ [/tex]
[tex] = 2 \times 3.14 \times 10 \times \frac{90}{360} \\ [/tex]
