Step-by-step explanation:
Depending on which formula you need you will need to solve for the separate shapes then add the answers together.
Cone: A=pi×r(r+hSquared +rSquared)
V=pi×rSquared×h/3
Cylinder: A=2pi×rh+2pi×rSquared
V=pi×rSquared ×h
3x+2y=1 x+y=3 solve please
Answer:
hope this helps, your answer should be (-5,8)
x = -5, y = 8
Explanation:
we're gonna start by subtracting
3x + 2y = 1 x+y=3
Rewrite the equation:
x + y = 3 , 3 x + 2 = 1
Step: Solve x + y = 3 for x:
x + y = 3
x + y + −y = 3 + −y (Add -y to both sides)
x = −y + 3
Step: Substitute −y + 3 for x in 3x + 2y = 1:
3x + 2y = 1
3 (−y + 3) + 2y = 1
−y + 9 = 1 (Simplify both sides of the equation)
−y + 9 + −9 = 1 + −9 (Add -9 to both sides)
−y = −8
−y/−1 = −8/−1 (Divide both sides by -1)
y=8
Step: Substitute 8 for y in x=−y+3:
x = −y + 3
x = −8 + 3
x = −5 (Simplify both sides of the equation)

An element with mass 590 grams decays by 19. 5% per minute. How much of the element is remaining after 15 minutes, to the nearest 10th of a gram?
Answer:
Step 1
Formulate a recursive sequence modeling the number of grams after n minutes.
we have that
100%-17.1%-------------- > 82.9%------------> 0.829
a(n) = 780*[0.829^n]
for n=19 minutes
a(19)=780*[0.829^(19)]=22.1121 g---------------> 22.1 g
the answer is 22.1 g

Variables y and x have a proportional relationship, where y = 20 when x = 4.
What is the value of x when y = 80?
Answer: x = 16
Step-by-step explanation: 20/4 = 5 and 80/5 = 16 so x = 16.
Answer:
16
Step-by-step explanation:
20 /4 = 5
80/5 = 16
16x5=80
Solve, using the substitution method.
m + n = 5
m – n = 3
There is no solution.
The solution is (2, –1)
The solution is (4, 1)
There are an infinite number of solutions.
Step-by-step explanation:
m-n = 3 becomes m=3+n
Substitute 3+n to m in m+n = 5
Therefore;
3+n+n = 5
3 + 2n = 5
2n = 2
n = 1
m - n = 3, n is 1
therefore;
m - 1 = 3
m = 4

A car travels along the highway to Austin at a steady speed. When it begins, it
is 500 miles from Austin. After 5 hours, it is 200 miles from Austin. Which
function describes the car's distance from Austin?
A. y = 60x-500
B. y=-60x+ 500
O c. y=-40x + 500
D. y = 60x + 200
Answer:
A
Step-by-step explanation:
x is hour. {from the question}
k = [tex]\frac{-500+200}{5}[/tex]
[tex]=\frac{-300}{5}[/tex]
[tex]=-60[/tex]
So [tex]y=-60x+500[/tex] choose A.
I hope this helps you
:)
The function that describes the car's distance from Austin is
y = -60x + 500.
What is a function?A function is a relationship between a number of inputs and outputs. A function is an association of inputs where each input is coupled with exactly one output. There is a range, codomain, and domain for every function.
Let x be the time period in hour.
And y is the distance from Austin.
We substitute the value of x =5 to the functions and see if it gives the output 200.
In A:
y = 60x -500
y = 60(5) - 500
y = -200
Distance is not negative. So, this is not a required function.
In B:
y = -60x +500
y = 200 miles.
This is a required function.
In C:
y = -40x + 500
y = -200 + 500
y = 300 miles.
This is not a required function.
In D:
y = 60x + 200
y = 300 + 200
y = 500 miles.
This is not a required function.
Therefore, y = -60x +500 is a required function.

Four different sets of objects contain 2,5, 6, and 7 objects, respectively. How
many unique combinations can be formed by picking one object from each
set?
Answer:
420 unique combinations
Step-by-step explanation:
Simply multiply:
2 * 5 * 6
There are 2 choices for the first set, and 5 choices for the second set. Each of the 2 choices from the first set can be combined with each of the 5 choices from the second set. So, there are 2 times 5 combinations from the first and second sets.

Corrie bought a new flat screen 70 inch television and a speaker system from a local electronics store on credit. The store will charge 18% per year compounded monthly. Their monthly payments are $204.80 for 4 years. What is the cash price of her purchase?
1. Identify the type of problem.
a. Future Value with compound interest.
b. Present Value with compound interest.
c. Present Value of an Annuity.
d. Future Value of an Annuity.
e. Future Value with simple interest.
2. Answer the question in the problem.
a. $4,881.09.
b. $5,262.72.
c. $9,261.57.
d. $7,247.31.
e. $6,971.91.
The cash price of her purchase would be $5262.79
How to find the compound interest?If n is the number of times the interested is compounded each year, and 'r' is the rate of compound interest annually, then the final amount after 't' years would be:
[tex]a = p(1 + \dfrac{r}{n})^{nt}[/tex]
The Present value = C [1 - (1+i)^(-n)]/i
C = the amount of payment per period
i = interest rate
n=number of payments
In this problem we have;
C = $174.80
i = 12% per year compounded monthly
= 12/(12 x 100)
= 0.01
n = 3 x 12 = 36 months
Present Value = 174.80[1 - (1+0.01)^(-36)]/0.01
Cash price = $5262.79
Hence, the cash price of her purchase would be $5262.79

A unicorn bought ten pieces of candy and paid $16. Large candies cost $4 each, medium-sized candies cost $2 a piece, and small candies come at $1 each. How many large candies did the unicorn buy?
There are three possible solutions:
6 medium-sized candies and 4 small candies. 1 large candy, 3 medium-sized candies and 6 small candies. 2 large candies and 8 small candies.How to find possible solution from a system of equations whose number of variables is greater than the number of equations
Let be [tex]x[/tex], [tex]y[/tex] and [tex]z[/tex] the quantities of large, medium-sized and small candies bought by the unicorn., which represent non-negative integers. After a quick reading, we build the following system of linear equations:
[tex]x + y + z = 10[/tex] (1)
[tex]4\cdot x +2\cdot y +z = 16[/tex] (2)
We notice that the number of variables is greater than the number of linear equations. Thus, the system have several solutions. By (1):
[tex]z = 10 - x - y[/tex]
(1) in (2):
[tex]4\cdot x + 2\cdot y + 10 - x - y = 16[/tex]
[tex]3\cdot x + y = 6[/tex] (3)
After some inspections, we find three possible solutions:
[tex]x = 0[/tex], [tex]y = 6[/tex], [tex]z = 4[/tex][tex]x = 1[/tex], [tex]y = 3[/tex], [tex]z = 6[/tex][tex]x = 2[/tex], [tex]y = 0[/tex], [tex]z = 8[/tex]There are three possible solutions:
