Answer:
8m/s.
Step-by-step explanation:
This question really depends on the answer because the units matter. Is it miles per second? Kilometers per second? We'll just assume it's meters per second so this question could be answered the easiest.
Meters/seconds=800meters/200seconds=(simplified) 8m/s

The volume of a hemisphere with radius x is V(x) = 2/3 πx3. The volume of a cube with a height of x is shown in the graph. When x = 2, which volume is greater?
The volume of the _________ is greater when x = 2.
(hemisphere or cubic)
Answer:hemisphere
Step-by-step explanation:
The volume of the hemisphere is greater when x = 2.
The formula for calculating the volume of a hemisphere is expressed as:
[tex]V=\frac{2}{3} \pi x^3[/tex]
Given that x = 2. Substitute x = 2 into the formula to get the volume of the hemisphere:
[tex]V=\frac{2}{3} \pi (2)^3\\V=\frac{16}{3}\pi\\V = 16.75 units ^ 3[/tex]
Next is to get the volume of a cube expressed as:
[tex]V = L^3\\Since \ L = x\\V = x^3\\V = 2^3\\V = 8 units^3[/tex]
Hence the volume of the hemisphere is greater when x = 2.

a movie theater charges $8 for adults and $5 for children. If there were 40 people altogether and theater collected $272
Answer: You can put this solution on YOUR website!
let's call the number of adults a and the number of children c.
so the total adults plus the total children equals 40 or a+c=40 or c=40-a
also we know that 8a+5c=272
substituting c's value in the 1st equation into the 2nd equation we get
8a+5(40-a)=272---->lets distribute that left side---->8a+200-5a=272
now let's combine like terms on either side of the equals sign.
3a=72 a=24
so we have highlight%2824-adults%29
and c=40-a(24)=highlight%2816-children%29

Hello Everyone! Please help me out anything you know helps. The topic is angles.
Answer: y=28 degrees
Step-by-step explanation:
To find angle B, all we have to do is subtract 145 from 180 since they're supplementary angles- so angle B is 35 degreesNow we can find x, by subtracting 14 from 35-> x=21We can create an equation using what we know about B to find y: 35= 63-ySolve the equation to get y=28 degreesIn this problem we used supplementary angles and algebra. We also used congruency.

How do you do this question?
Step-by-step explanation:
Start with the series representation for eˣ.
eˣ = ∑ₙ₌₀°° xⁿ / n!
Substitute -x².
e^(-x²) = ∑ₙ₌₀°° (-x²)ⁿ / n!
e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ) / n!
Multiply by x².
x² e^(-x²) = x² ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ) / n!
x² e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ⁺²) / n!
Integrate both sides (use power rule).
∫ x² e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (x²ⁿ⁺³) / ((2n + 3) n!)
Evaluate between x=0 and x=0.5.
∫ x² e^(-x²) = ∑ₙ₌₀°° (-1)ⁿ (0.5²ⁿ⁺³) / ((2n + 3) n!)
This is an alternating series, so use alternating series estimation.
(0.5²⁽ⁿ⁺¹⁾⁺³) / ((2(n+1) + 3) (n+1)!) ≤ 0.001
(0.5²ⁿ⁺⁵) / ((2n + 5) (n+1)!) ≤ 0.001
n ≥ 1
So the estimate of the integral is the sum of the first two terms (n=0 and n=1).
I = (-1)⁰ (0.5³) / ((3) 0!) + (-1)¹ (0.5²⁺³) / ((2 + 3) 1!)
I = (0.5³) / 3 − (0.5⁵) / 5
I = 1/24 − 1/160
I = 17/480
I = 0.0354

a nursery sells kentucky bluegrass seed for $5.75 per pound and tall fescue seed for $4.50 per pound. the nursery sells a mixture of the two kinds of seed for $5.25 per pound. let k represent the amount of kentucky blue grass seed the nusery uses in in 5 pounds of the mixture
Answer:
[tex]k=3[/tex]
Step-by-step explanation:
Given that:
Per pound cost of kentucky bluegrass seed = $5.75
Per pound cost of tall fescue seed = $4.50
Per pound cost of mixture of seeds = $5.25
[tex]k[/tex] is the amount of kentucky blue grass.
Total amount of the mixture = 5 pounds
Therefore, amount of tall fescue seed = (5 - [tex]k[/tex]) pounds
To find:
The value of [tex]k[/tex].
Cost of [tex]k[/tex] pounds of kentucky bluegrass seed = [tex]\$5.75k[/tex]
Cost of (5 - [tex]k[/tex]) pounds of tall fescue seed = [tex]\$(5-k)4.50[/tex]
As per question statement:
[tex]5.75k+(5-k)4.50=5.25\times 5\\\Rightarrow 575k+5\times 450 -450k=525\times5\\\Rightarrow 125k=75\times5\\\Rightarrow k =3\ pounds[/tex]
Amount of kentucky blue grass seed used = 3 pounds
Amount of tall fescue seed used = 5-3 = 2 pounds

to calculate the perimeter of the parallelogram you need the two side lengths 12 inches and 15 inches
Answer:
the answer would be 54
Step-by-step explanation:
If the shape is a parallelogram then two sides will be equal lengths. same with the other two sides.
if you need the perimeter then you need to add the lengths of all the sides. so that would be 12 12 15 and 15. Add those together and you get 54 inches.

Answer:
B. 50
Step-by-step explanation:
The alternate interior angles at transversal t across parallel lines AB and CD will be congruent.
2x +40 = x +90
x = 50 . . . . . . . . . . . subtract x+40
The value of x is 50.
_____
Check
2x+40 = 2×50 +40 = 140
x+90 = 50 +90 = 140 . . . . so the obtuse angles are congruent, as they should be
___
Additional comment
The lines AB and CD are not shown as being parallel. We have to assume they are, or we cannot work the problem.
Twenty five more than twice a number is fifty five. What is the number?
Answer:
15
Step-by-step explanation:
15x2 = 30
30+25 = 55
Answer:
Step-by-step explanation:
Note all operations:
twenty-five more than → addition → +25twice a number → multiplication → ×2is fifty-five → equal to → =55Create an equation, and make the unknown number be x. 25 is added to x multiplied by 2, which, in all, equals 55:
[tex]2x+25=55[/tex]
Now solve for x. Subtract 25 from both sides:
[tex]2x+25-25=55-25\\\\2x=30[/tex]
Divide both sides by 2:
[tex]\frac{2x}{2}=\frac{30}{2} \\\\x=15[/tex]
The number is equal to 15.
:Done
CHECK:
Insert the value of x to see if it is true:
[tex]2(15)+25=55\\\\30+25=55\\\\55=55[/tex]
This is true, so the value of x is also true.
