Answer:
The formula for volume of a cone is area of a circle times height, divided by 3.
Therefore volume is pi times radius squared times height, divided by 3.
V = (3.14)(14)^2 (14)/3
V = (3.14) (196)(14)/3
V = (3.14) (2744)/3
V = 8616.16/3
V = 2872.05333
to the nearest hundredth is 2872.05 cubic yards.

In 1900 Kansas City had a population of 163,000In 2020 it has a population of 1,686,000Show me exponential growthHow many years after 1900Did it take for the population to double
The exponential growth is 1.95% and after 35.72 years the population will double.
What is an exponential function?It is defined as the function that rapidly increases and the value of the exponential function is always a positive. It denotes with exponent [tex]\rm y = a^x[/tex]
where a is a constant and a>1
Let's suppose the exponential growth function is:
[tex]\rm y = Ae^{rt}[/tex]
A = 163,000
y = 1,686,000
t = 2020 – 1900 = 120 years
Plug all the values in the function:
[tex]\rm 1686000 = 163000e^{120r}[/tex]
[tex]\rm e^{120r} = 10.343[/tex]
Taking ln both side and solving:
r = 0.0194
r = 1.946 ≈ 1.95%
[tex]\rm 2A = Ae^{0.0194t}[/tex] (the population to double)
After solving:
t = 35.72 years
Thus, the exponential growth is 1.95% and after 35.72 years the population will double.

if I spend $9.79, how many ways can I receive change from a ten-dollar bill
Answer:
You can can receive 9 different ways to receive change from a ten-dollar bill
Step-by-step explanation:
- Total spent: $9.79
- How much payed: $10
The change will be $10 - $9.79 = 0.21
- Change: $0.21
Possible coins:
penny: 1¢ ($0.01)
nickel: 5¢ ($0.05)
dime: 10¢ ($0.10)
25¢ (this is too high, can't use)
Combinations:
To get 21...
- not ideal but 21 pennies
- 11 pennies + 1 dime
- 1 penny + 2 dimes
- 16 pennies + 1 nickle
- 11 pennies + 2 nickels
- 6 pennies + 3 nickels
- 1 penny + 4 nickels
- dime + nickle + 6 pennies
- dime + 2 nickels + 1 penny
using dimes: [10, 10, 1] [10, 5, 5, 1] [10, 5, 6x1] [10, 11x1]
using nickels: [5, 5, 5, 5, 1] [5, 5, 5, 6x1] [5, 5, 11x1] [5, 16x1]
using pennies: 21x1
So, there are 9 ways to make the change.

Deondra took a taxi from her house to the airport. The taxi company charged a pick-up fee of $3.20 plus $2 per mile. The total fare was $47.20, not including the tip. How many miles was the taxi ride?
This is our y intercept
Rate of pay=$2 per mileThis is our slope or rate of change
So
The equation becomes
d=2m+3.20Where m is miles driven
47.20=2m+3.202m=44.00m=22.0milesThe no. of miles not including any tip the taxi traveled is 22 miles.
What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, The taxi company charged a pick-up fee of $3.20 plus $2 per mile.
Let, 'm' be the no. of miles and the total fare was $47.20.
Therefore, The numerical form of these statements is,
2m + 3.20 = 47.20.
2m = 47.20 - 3.20.
2m = 44.
m = 44/2.
m = 22.
So, The taxi traveled 22 miles.

Question 22: 4 pts Find the probability of rolling a 4 on a number cube and then choosing a red ball at random from a bag of 8 blue and 6 red balls.
Answer:
1/14
Step-by-step explanation:
a four out of possible 6 rolls = 1/6
6 red out of 14 balls 6/14
1/6 * 6/14 = 1/14
The Probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.
What is Probability?Probability is "possibility that deals with the chance of occurrence of random event" .
According to the question,
A cube has 6 faces that is (1,2,3,4,5,6). Total number of faces n(s) = 6.
Probability formula = (Number of favorable event)/(Total number of event).
Probability of taking 4, P(4) = 1/6.
A bag containing 8 blue and 6 red balls. Total number of balls in a bag n(s) = 14.
Probability of taking red balls P(red balls) = 6/14.
In order to find that probability of rolling a 4 on a number cube and then choosing a red a ball at random only if multiply P(4) by P(red balls).
P(4) × P(red balls) = [tex]\frac{1}{6}[/tex] × [tex]\frac{6}{14}[/tex] = [tex]\frac{1}{14}[/tex].
Hence, probability of rolling a 4 on a number cube and then choosing a red a ball at random is 1/14.

Step-by-step explanation:
14.666666667*3 because 1 yard= 3 feet
One yard is 3 feet, which means we will have to mutliple 14 2/3 by 3.
14 x 3 =42
2/3 of a yard is 2 feet, which means we must add 2 to 42--->

PQRS is a parallelogram. Angle QSP = 47°. Angle QSR = 24°, PST is a straight line.
Answer:
The value of x = 109°
angle PQS = 24°
Step-by-step explanation:
24° + 47° + x = 180° { angles on straight line }
=> 71 ° + x = 180°
=> x = 180° - 71°
=> x = 109°
Now,
Angle PQS = 24°
angle PQS = angle QSR { alternative angle }
Step-by-step explanation:
a)(i) x=109°
(ii)It's given that PST is straight line then PST=180°,and
PST=QSP+QSR+x
180° =47°+24°+x
180°=71°+x
180°-71°=x
109°=x
b)(i)PQS=71°
(ii)we know opposite angles are equal in parallelogram
so PSR=PQR=71°

Please show your work! I'll give you Brainliest as well lol, thanks!
Step-by-step explanation:
the area of such a regular shape with n sides is the sum of n isoceles triangles (meaning each triangle has equally long legs) from the center to 2 neighboring corners.
the area of a triangle is
baseline × height / 2
so, for these triangles that means
shape side length × apothem / 2
in our case, n = 6, the side length = 5 cm, the apothem is 4.3 cm. and we get as total area
6 × 5×4.3 / 2 = 3 × 5 × 4.3 = 15 × 4.3 = 64.5 cm²

Your Slope-Intercept Form: y=2x-7
1.) Find (0,-7) that shall be your y-intercept.
2.) From your y-intercept [ (0,-7) ] you need to go up 2 and over 1.
**Meaning go up on the y-axis 2 times and go right 1.
Using the following diagram. Solve for N
[tex]\text{Vertical angles are equal, so}[/tex]
[tex]~~~~~~15n-2 = 13n+12\\\\\implies 15n-13n = 12+2\\ \\\implies 2n = 14\\\\\implies n = \dfrac{14}2 \\\\\implies n = 7[/tex]
Use the Venn diagram to calculate probabilities.
Circles A, B, and C overlap. Circle A contains 3, circle B contains 9, and circle C contains 6. The overlap of A and B contains 1, the overlap of B and C contains 4, and the overlap of C and A contains 7. The overlap of the 3 circles contains 6. Number 8 is outside of the circles.
Which probability is correct?
P(A|B) = One-half
P(B|A) = StartFraction 7 Over 20 EndFraction
P(A|C) = StartFraction 6 Over 23 EndFraction
P(C|A) = StartFraction 13 Over 17 EndFraction
Using the probability concept and the Venn diagram described, the correct option is given by:
P(C|A) = 13/17.
What is a probability?A probability is given by the number of desired outcomes divided by the number of total outcomes.
P(A|B) is given by the sum of the values that involve both A and B by the sum of all values that involve B, hence:
D = 1(overlap of A and B) + 6(Overlap of the 3).T = 9 + 1 + 4 + 6 = 20.Hence:
P(A|B) = 7/20.
Following the same logic, we have that:
P(B|A) = (1 + 6)/(3 + 1 + 7 + 6) = 7/17P(A|C) = (7 + 6)/(6 + 4 + 7 + 6) = 13/23P(C|A) = (7 + 6)/ (3 + 1 + 7 + 6) = 13/17.Hence the last option is correct.
