Answer:
18/50 or 9/25
Step-by-step explanation:
so first you add all the info
15 + 18 + 9 + 8
this will be your denominator
50
50 balloons in total
now just put 18/50 because you are looking for the probability of yellow balloons
Answer:
C. 9/25
Step-by-step explanation:
Total number of drawings of balloons = 15 + 18 + 9 + 8 = 50
Number of times a yellow balloon was chosen = 18
p(choosing yellow balloon) = 18/50 = 9/25
Answer: 9/25
What is the probability of flipping heads and rolling a two?
Answer:
1/12
Step-by-step explanation:
Chance of flipping heads: 1/2
Chance of rolling a two: 1/6
1/2 x 1/6 = 1/12
Answer:
1/2 x 1/6 = 1/12
probability of flipping head =1/2
rolling a two = 1/6
probability of flipping heads and rolling a two = 1/2 x 1/6
The height $h$ and the base area $B$ of a cone are given. Find the volume of the cone. Write your answer in terms of $\pi$ .
$h=6$ units
$B=4\pi$ square units
The volume is__ cubic units.
Answer:
(i) 84 cm.
(ii) 5635π cm^2
Step-by-step explanation:
(i)
The volume of the cone = 1/3 π r^2 h
= 1/3 π 35^2 h.
The volume of the hemisphere = 2/3 π 35^3.
As the volume of the cone is 1 1/5 ( = 6/5) times the volume of the hemisphere:
1/3 π 35^2 h = 2/3 π 35^3 * 6/5
h = 2/3 π 35^3 * 6/5 / 1/3 π 35^2
h = 84 cm (answer).
(ii) Surface area of the hemisphere = 2 π * 35^2 = 2450π cm^2.
Surface area of the cone = π r l where l = slant height.
l = √(35^2 + 84^2) = 91 cm.
So the surface area of the cone = 35*91 π = 3185π.
So the total surface area of the solid is 3185π + 2450π
= 5635π cm^2.
i hope this work for you
The height and the base area of the cone are 6 units and 4π square units. Then the volume of the cone is 24π.
What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The height (h = 6) and the base area (b = 4π) of a cone is given.
Then the volume of the cone will be
Volume = b × h
Volume = 4π × 6
Volume = 24π

Answer:
original coordinates A[-4,5], B[-3,1], C[-5,2
new coordinates [3,1], B[2,5] C[4,4]
Step-by-step explanation:
ok so the x is the horazontal line and the Y is the vertical line when your writing cooodinates you always write the X first then the Y. so to find the origanal corrdinates which i'm assuming are the coordinates for the blue triangle you have to find the first point so the one labled A, you look at the numbers on X so the horizontal line, and find out which number on that line has point A on it and you record that number this is the X then you look at the numbers on the Y line, (the vertical line) and see which number has point A on it and record this number this is the Y do this for all the other points and you will have all of their coordinates.

For the following rectangular prism, find the length of the diagonal connecting A to B. Round to the nearest tenth.
Answer:
I think it is 192
Step-by-step explanation:
Volume of cube: 5 x 4 x 8 = 160
Area of diagonal: 160/2 = 80
Length of diagonal: 80 / 0.5 x 3 = 480
AB = 480 / 5 x 2 = 192

Worth 10 points . . .
Answer:
12 guests(13 including yourself), 78 ounces of dough, and 52 ounces of sauce.
Step-by-step explanation:
So what you want to do is to first add up the dough and the sauce which is 10. then you want to divide 130 by 10 and you get 13(130/10=13) Now we subtract 1 from 13 and that how many guests you have which is 12. now we time 6 by 13 which is 78(6*13=78) so 78 ounces of dough. Now we time 4 by 13 and we get 52(4*13=52) so 52 ounces of sauce. Now to make sure it's right we need to add 78 and 52 together and we get 130(78+52=130) And that's all

The balance of an account after t years can be found using the expression 6000(1.02)^t where the initial balance was $6000. By what percent does the account increase annually? a 1.02% b 102% c 0.02% d 2%
9514 1404 393
Answer:
(d) 2%
Step-by-step explanation:
The base of the exponent is the "growth factor". It is 1 more than the "growth rate", the fraction of change in 1 year.
growth factor = 1 + growth rate
1.02 = 1 + 0.02
growth rate = 0.02 = 2%
The account increases 2% annually.
