Answer:
V = 4000 cm^3
Step-by-step explanation:
The volume of the sphere is given by
V = 4/3 pi r^3
We are given the radius of 10 and are to use 3 for pi
V = 4/3 (3) * (10)^3
V = 4/3 *3 * 1000
V = 4000 cm^3

The figure created with the points (-2, -3), (-2, 5), (1, -3) and (1, 5) is a rectangle.
Which shape is a rectangle?
A rectangle is oblong. It has two pairs of parallel sides and four right angles. A rectangle can also be known as an equiangular quadrilateral. This is because a rectangle is a quadrilateral shape (4-sided shape) that hasparallel sides, equal to one another, and all 4 corners have angles that are90º.

Step-by-step explanation:
Let x, and x+1 be the consecutive numbers.
[tex]x + (x + 1) = 37[/tex]
[tex]2x + 1 = 37[/tex]
[tex]2x = 36[/tex]
[tex]x = 18[/tex]
Plug in 18 for x+1,
[tex]18 + 1 = 19[/tex]
So the numbers is 18,19
Answer:
18 and 19
Step-by-step explanation:
if you have two consecutive numbers, then using algebra, one unknown number is x and the other unknown consecutive number is x + 1
The equation x + x + 1 = 37
To solve this equation subtract 1 from both sides as one does in algebra.
x + x + 1 = 37 → x + x + 1 - 1 = 37 - 1
Now you have the equation x + x = 36
This can rewrite this as 2x = 36 2x means 2 times the value of x
To solve this part of the equation divide both sides by 2
2x / 2 = 36 / 2
x = 18
The next consecutive number x + 1 = 19, (18) + 1 = 19
check this by adding. 18 + 19 = 37.
PLEASE HELP SOON! Please answer the question and explain step by step how you got your answer. Julian is using a biking app that compares his position to a simulated biker traveling Julian's target speed. When Julian is behind the simulated biker, he has a negative position. Julian sets the simulated biker to a speed of 20 km/h. After he rides his bike for 15 minutes, Julian's app reports a position of -2 1/4 km.
What has Julian's average speed been so far?
Answers
Answer:
11 km/h
Step-by-step explanation:
What I did is found out how fast the simulated biker traveled for 15 minutes, by doing
[tex]\frac{20}{4}[/tex] = 5
Since 15 minutes is 1/4 of an hour. Or you could do 20/60 = 1/3, 1/3 being how much the biker traveled in a minute and multiply that by 15
15×[tex]\frac{1}{3}[/tex] = 5
Now we know that the biker traveled 5 km, now subtract 5 by [tex]2 \frac {1}{4}[/tex]
5 - [tex]2 \frac {1}{4}[/tex] = [tex]2 \frac {3}{4}[/tex]
Julian traveled [tex]2 \frac {3}{4}[/tex] in 15 minutes, now to find his average speed you multiply [tex]2 \frac {3}{4}[/tex] by 4 since [tex]2 \frac {3}{4}[/tex] is the distance traveled in 1/4 an hour.
[tex]2 \frac {3}{4}[/tex] × 4 = 11
11 km/h

Answer:
A.) 15984.42cm^2/5088πcm^3
B.) 3466.56cm^2/1104πcm^2
Step-by-step explanation:
A.) fine the V of the cone and then cylinder then add them.
B.) The cone you have to find the LA (lateral area) to do that you would do is find S (slant) so you would do 12^2+16^2 which is 400 then u have to find the square root of it which is 20 which is that slant of the cone. After that you would do 12x20 which gives 240 that would be the LA of the cone.
Then you would find the LA of the cylinder which you have to do is 30x12 which is 360 then multiply it by 2 which gives 720.
Lastly you find the area of the base which in this case is a circle and that would be 144 add all of them then get the SA

Step-by-step explanation:
Basically just plug in the information given to you into the equation.
π (pi) = 3.14
r (radius) = 3 (radius is 1/2 of diameter, and the diameter is 6; half of 6 is 3 so that is the radius)
h (height) = 10
Therefore your equation set up should look like:
2(3.14)(3²) + 2(3.14)(3)(10) = 244.92

The number of pieces of popcorn in a large movie theatre popcorn bucket is normally distributed, with a mean of 1610 and a standard deviation of 10. Approximately what percentage of buckets contain between 1600 and 1620 pieces of popcorn?
Approximately 68%
Approximately 75%
Approximately 95%
Approximately 99.7%
Answers
Answer:
A. Approximately 68%
Step-by-step explanation:
The number of pieces of popcorn in a bucket is normally distributed.
Mean = μ = 1610
Standard deviation = б = 10
We know that in a normal distribution, approximately 34% of bags will fall within one standard deviation on one side. On both sides within the range of 1 standard deviation, 34 + 34 = 68 % of bags will fall.
A table of normal distribution of the mean is attached for better understanding.
Our range is:
1600 to 1620
1610 - 10 to 1610 + 10
μ ± б
mean ± 1 standard deviation
Our range is within 1 standard deviation. Hence, Approximately 68% of buckets contain between 1600 and 1620 pieces of popcorn.
its the only one that works
