Answer:
A. 2x^2+4
B. 5x^3 - 4x^2 + 3x - 12
C. Yes
Step-by-step explanation:
Given:
Side 1=3x^2-4x-1
Side 2=4x-x^2+5
Perimeter=5x^3-2x^2+3x-8
Perimeter=side 1 + Side 2 + Side 3
A. Total lenght of the two sides
Side 1 + Side 2=(3x^2-4x-1) + (4x-x^2+5)
=3x^2 - 4x - 1 + 4x - x^2 + 5
=3x^2 - x^2 - 4x + 4x - 1 + 5
=2x^2+4
B. Length of the third side
Perimeter=side 1 + Side 2 + Side 3
Recall,
Side 1 + side 2=2x^2+4
Perimeter= (side 1 + Side 2) + Side 3
5x^3-2x^2+3x-8 = 2x^2+4 + side 3
5x^3-2x^2+3x-8 - (2x^2+4) = side
3
5x^3 - 2x^2 + 3x - 8 - 2x^2 - 4 = Side 3
5x^3 - 2x^2 - 2x^2 + 3x - 8 - 4 = Side 3
=5x^3-4x^2+3x-12
Side 3= 5x^3 - 4x^2 + 3x - 12

Sally bought 4 chocolate bars and 8 lollipops and paid $8.00. Josh bought 3 chocolate bars and 10 lollipops and paid $7.00.
What is the cost of a lollipop? Enter your answer as a decimal
Answer:
Lollipops cost $0.25
Step-by-step explanation:
4C + 8L = $8.00
3C + 10L = $7.00. We need to cancel out chocolate bars
-12C - 24L = $-24.00 Mulitply by -3
12 C + 40L = $28.00 Muliply by 4 Next simplify
16L = $4.00 Divide both sides by 16
L = $0.25
WE CAN EVEN CHECK OUR WORK
4C + 8(0.25) = $8.00
4C = $6.00
C = 1.5
3(1.5) + 10(.25) = $7.00
4.5 + 2.5 = 7

If a cylindrical vase has a 63 cubic centimeter volume an a cone has the same height and radius as the cylinder what is the volume of the cone
Answer:
[tex]21cm^{3}[/tex]
Step-by-step explanation:
According to the problem, calculation of given data are as follows,
Volume of cylindrical vase = [tex]63cm^{3}[/tex]
As, Cone has same height and radius as cylinder, than we can calculate volume of cone by using following formula,
Volume of cone = [tex]\frac{1}{3}[/tex] × Volume of cylindrical vase
By putting the value, we get
Volume of cone = [tex]\frac{1}{3}[/tex] × 63
Volume of cone = [tex]21cm^{3}[/tex]
Jada walks up to a tank of water than can hold up to 10 gallons. When it is active, a drain empties water from the tank at a constant rate. When Jada first sees the tank, it contains 7 gallons of water. Three minutes later, the tank contains 5 gallons of water.
a. At what rate is the amount of water in the tank changing? Use a signed number, and include the unit of measurement in your answer.
b. How many more minutes will it take for the tank to drain completely? Explain or show your reasoning.
c. How many minutes before Jada arrived was the water tank completely full? Explain or show your reasoning.
Answer:
a. rate to empty the tank = - 2/3 gal/min
b, 7.5 min to empty the tank
c. 4.5 min.
Step-by-step explanation:
I use the formula that the work done = rate of work times the time working = W = rt
The work in this problem is emptying the tank.
a. The rate to empty the tank is -2 gal/3 min or - 2/3 gal/min
b. 5/(2/3) = 15/2 = 7.5 min to empty the tank
c. Since 3 gal. had already drained, 3/(2/3) = 9/2 = 4.5 min.

Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded
continuously. Assuming no deposits or withdrawals are made, how long would it
take, to the nearest year, for the value of the account to reach $1,830?
Answer:
14
Step-by-step explanation:
The value of the account will reach to $1,830 in 15 years.
What is compound interest?Compound interest simply means that the interest associated with a bank account, loan, or investment increases exponentially over time.
Given that, Mackenzie invested $770 in an account paying an interest rate of 6.1% compounded continuously after a certain period of time the mount becomes $1830
We know that,
[tex]A = P(1+r)^n[/tex]
Where, A = amount, P = principal, r = rate and n = time.
1830 = 770(1+0.061)ⁿ
1830 / 770 = (1.061)ⁿ
2.37 = (1.061)ⁿ
Taking log both side,
log(2.37) = n log(1.061)
n = log(2.37) / log(1.061)
n = 14.57 ≈ 15
Hence, the value of the account will reach to $1,830 in 15 years.

What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the percentage of amount spent on fruit be = A
Let the total amount spent by Lucy at the store be = $ 60
Let the amount spent by Lucy on fruit at the store be = $ 36
So , the equation is
Percentage of amount spent on fruit A = ( amount spent by Lucy on fruit at the store / total amount spent by Lucy at the store ) x 100
Substituting the values in the equation , we get
Percentage of amount spent on fruit A = ( 36 / 60 ) x 100
Percentage of amount spent on fruit A = ( 6 / 10 ) x 100
Percentage of amount spent on fruit A = 60 %
Therefore , the value of A is 60 %
Hence ,
The percentage of amount Lucy spent on fruit is 60 % of the total amount

The pizza store is announcing a new sale for their large cheese pizza. The pizza is now 40% off its original price. If the original price is 16 dollars how much is the new price?
Answer: $9.60
Step-by-step explanation:
First, we need to calculate the discount given on the pizza. This will be:
= 40% × $16.
= 40/100 × $16
= 0.4 × $16
= $6.40
Then the new price will be gotten by subtracting the amount given off from the original price. This Will be:
= $16 - $6.40.
= $9.60
The new price is $9.60

the question is: find the value of x for each equation below and the numbers is
-x+3=3x-2
1.5x-3=2.25x
-1/3x+2=3x-1
Answer:
1. x=5/4
2. x=-4
3. x= 9/10
Step-by-step explanation:
Let's solve your equation step-by-step.
−x+3=3x−2
Step 1: Subtract 3x from both sides.
−x+3−3x=3x−2−3x
−4x+3=−2
Step 2: Subtract 3 from both sides.
−4x+3−3=−2−3
−4x=−5
Step 3: Divide both sides by -4.
−4x/−4 = −5/ −4
x= 5/4
Answer:
x= 5/4 (5 over 4)
Let's solve your equation step-by-step.
1.5x−3=2.25x
Step 1: Subtract 2.25x from both sides.
1.5x−3−2.25x=2.25x−2.25x
−0.75x−3=0
Step 2: Add 3 to both sides.
−0.75x−3+3=0+3
−0.75x=3
Step 3: Divide both sides by -0.75.
−0.75x/−0.75=3/−0.75
x=−4
Answer:
x=−4
Let's solve your equation step-by-step.
−1/3x+2=3x−1
Step 1: Subtract 3x from both sides.
−1/3x+2−3x=3x−1−3x
−10/3x+2=−1
Step 2: Subtract 2 from both sides.
−10/3x+2−2=−1−2
−10/3x=−3
Step 3: Multiply both sides by 3/(-10).
(3/−10)*(−10/3x)=(3/−10)*(−3)
