Find the surface area and the volume of the cone:
*Hint: Remember that 10 is the slant height, not the cone height. Use Pythagorean Theorem to find
height.
Answer:
surface area= 301.6
volume=301.6 again Imao I'm not sure how right that is
What is the equation of the circle?
Answer:
x² + y² = 3
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( where r is the radius )
Using Pythagoras' identity in right triangle CRT
CR² = 1² + ([tex]\sqrt{2}[/tex] )² = 1 + 2 = 3 ( take the square root of both sides )
CR = r = [tex]\sqrt{3}[/tex] , then
x² + y² = ([tex]\sqrt{3}[/tex] )² , that is
x² + y² = 3

Given that
X2: (20 – 3x) = 1 : 2
find the possible values of x.
Answer:
Step-by-step explanation: x^2 : (20 - 3x) = 1 : 2
2x^2 + 3x - 20 = 0
(x + 4)(2x - 5) = 0
Solution:
x = -4
x = 5/2
Answer:
x= 2.5
x= 2.5x = - 4
Step-by-step explanation:
1:2
x² : (20 - 3x)
x2 : x 1
2x² : 1(20-3x)
2x² : 20 - 3x
+3x , then - 20
2x² + 3x - 20 = 0
2 x - 20 = - 40
x to get - 40
+ to get 3
(8 x - 5 = -40 & 8 + - 5 = 3)
Split 3x into 8x & - 5x, then factorise:
2x^2 + 3x - 20 = 0
2x^2 + 8x - 5x - 20 = 0
2x(x+4) - 5(x + 4)
(2x-5) (x+4) =0
2x - 5 = 0
+5
2x = 5
÷2
x = 2.5
x+4=0
-4
x = - 4
x=2.5,-4
Hope this helps!
Max and Jay Are running a lemonade stand they spent $12 on all the material and charge $1.50 for each cup of lemonade write an equation that will allow you to calculate the profit (P) if you are told the number of cups (c) that are sold.
Answer:
P = $1.50c - $12
Step-by-step explanation:
profit = total revenue - total cost
total revenue = price per cup x total cup sold = $1.5 x c = 1.5c
Cost = $12
A bag with 5 pound of potatoes costs $3.20. How much do 12 pounds of potatoes cost at the same rate?
Answer:
$7.68
Step-by-step explanation:
You must find the rate first, so in order to do that you divide the price by the quantity which is
3.20/5
which equals .64 and this number is the cost of potatoes per pound so to find 12 pounds you do
.64 * 12
which equals 7.68
Answer: 7.68
Step-by-step explanation:
First you find the rate where you do 3.20/5 which equals .64
Then you multiply the 12 and .64 and get 7.68

In the year 2000, the population of Virginia was about 7,400,000.
Between the years 2000 and 2004, the population in Virginia grew
at a rate of 5.4%. At this growth rate, the function f(x) = 7,400,000 (1.054)*
gives the population x years after 2000.
9. In what year will the population reach 15,000,000?
10. In what year will the population reach 20,000,000?
Answer:
Step-by-step explanation: 7,400,000/5.4%=13,703.7
grows by 13,703.7 every 4 years

( help please :) )
Answer:
33.333%
Step-by-step explanation:
a 6 sided die has the number 1,2,3,4,5,6. 2 are less than three so the chances of getting the of getting a number less than 3 is 2/6, simplified 1/3.

find the length of the missing side in the following examples
Answer: 1. 6.1
2. 13
3. 5.4
4. 5.7
5. 10.4
6. 31
Step-by-step explanation:
I got the values of the missing sides by doing the Pythagorean theoreom. Therefore, I had to find the length of the hypotenuse. a^2+b^2=c^2
a and b are the values of the sides given, and we have to find the value of c. So, for instance on number one 6 and 3 are a b. (6)^2+(3)^2= 45. Now we have to find the square root of 45. The square root of 45 is 6.7082039325.
So the value of the missing side in number one is 6.7.
how do you solve this??
Answer:
The sum of this entire line is 180, so to solve this we would subtract 20 from 180, which means x = 160.

To test the effect of partial day care on academic performance in young children, you plan to use two groups of 4-year-olds from the same preschool class: one group is made up of randomly selected children who attend part-time day care; the other group includes randomly selected children who do not attend any day care other than preschool. Both groups will complete a brief test of academic performance during a regular preschool class. Which type of test should you use to compare the mean scores of the two groups
Answer:
Independent samples t test
Step-by-step explanation:
The experiment performed above, required the independent samples t test as it invilves two seperate and distinct, otherwise called independent groups whereby one group has no effect on the outcome of the other. The means a ND standard deviation of the first group (4 year Olds who attend part time daycare) and the other group (4 year Olds who do not attend part time daycare). Hence, the comparison can be made using the two independent samples t test ;

C. 75°
D. 15°
9514 1404 393
Answer:
A. 105°

∠XZY = 105°
How long will it take Eniola to save $5,000 if she started with $500 and found a rate of 6.2%? Round to the nearest whole number.
Answer:
the time period is 38.28 years
Step-by-step explanation:
The computation of the time period is shown below:
Given that
RATE = 6.2%
PV = $500
PMT = $0
FV = $5,000
The formula is shown below:
= NPER(RATE;PMT;-PV;FV;TYPE)
After applying the above formula, the time period is 38.28 years
Hence, in order to save $5,000 it would take 38.28 years
