Grant spent half of his weekly allowance. Then he earned $5 back by doing the dishes. What is his weekly allowance if he ended with $15?
Answer:
Grant's weekly allowance is $20.
Step-by-step explanation:
We know that Grant ended with $15. We can say that Grant's weekly allowance is x.
x/2 + 5 = 15
Now to solve:
x/2 + 5 - 5 = 15 - 5 (subtract 5 from both sides to isolate the x/2)
x/2 = 10
x/2 * 2 = 10 * 2 (multiply both sides by 2 to isolate the x)
x = 20
Grant's weekly allowance is $20.
A contractor bought 8.2 ft^2 of sheet metal. He had used 4.9ft^2 so far and has $ 59.40 worth of sheet metal remaining. The equation 8.2x-4.9x=59.4 represents how much sheet metal is remaining and the cost of the remaining amount. How much does sheet metal cost per square foot?
Answer: Each square foot of metal costs $14.97
Step-by-step explanation:
He initially had 8.2 ft^2 of metal.
He used 4.9ft^2 of metal, then he now has:
8.2 ft^2 - 4.9 ft^2 = 3.3 ft^2
And this 3.3 ft^2 is whort $49.40
Then if X is the cost per square foot, we have the equation:
3.3ft^2*X = $49.40
We can solve it for X as:
X = ($49.40/3.3ft^2) = $14.97 ft^-2
This means that each square foot costs $14.97

Amy is putting a new floor in her bathroom. She created a scale drawing of her bathroom floor using a scale of 1/3 inch= 1 foot. In the drawing, the bathroom measure 3 inches by 3 1/3 inches. Amy is purchasing squares tiles that measure 1/3 foot on each side. The cost of each tile is $3.00. How much will Amy pay for the tiles for bathroom floor
Answer:
$2,430
Step-by-step explanation:
Scale of the drawing = ⅓ in. to 1 ft
Measurement of the bathroom on paper = 3 in. by 3⅓ in.
Actual measurement of the bathroom:
3*3 = 9 ft
3⅓ * 3 = 10 ft
Area of the bathroom = 9*10 = 90 ft²
Let's find how many square tiles would cover 90 ft².
The side length of 1 tile is said to be ⅓ ft.
Therefore, the area of 1 tile would be ⅓*⅓ = ⅑ ft².
Number of tiles that would cover 90 ft² would be:
90/⅑ = 90*9
= 810 tiles
If 1 tile cost $3.00, therefore 810 tiles would cost:
810 * 3 = $2,430.

A new bank customer with $3,000 wants to open a money market account. The bank is offering a simple interest rate of 1.1%. What will be the account balance after 20 years?
Answer: The interest customer earn in 20 years will be, $ 660
Step-by-step explanation :
Given:
Principle = $3000
Interest rate = 1.1 %
Time = 20 years
Now we have to determine the simple interest.
Formula used :
where,
P = principle
R = interest rate
T = time
S.I = simple interest
Now put all the given values in the above formula, we get:
Thus, the interest customer earn in 20 years will be, $ 660

can anyone solve 84=4(1 - 4g) step by step?
Answer:
g= -5
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
84-(4*(1-4*g))=0
84 - 4 • (1 - 4g) = 0
3.1 Pull out like factors :
16g + 80 = 16 • (g + 5)
16 • (g + 5) = 0
4.1 Solve : 16 = 0
This equation has no solution.
A a non-zero constant never equals zero.
4.2 Solve : g+5 = 0
Subtract 5 from both sides of the equation :
g = -5

Answer:
g = -5

Step-by-step explanation:
Step 1: Define equation
84 = 4(1 - 4g)
Step 2: Solve for g
Distribute 4: 84 = 4 - 16gIsolate g term: 80 = -16gIsolate g: -5 = gRewrite: g = -5Step 3: Check
Plug in g into the original equation to verify it's a solution.
Substitute in g: 84 = 4(1 - 4(-5))Multiply: 84 = 4(1 + 20)Add: 84 = 4(21)Multiply: 84 = 84Here we see that 84 does indeed equal 84.
∴ g = -5 is a solution of the equation.

Answer:
A = $5183.36
Step-by-step explanation:
Compound Interest
It occurs when the interest is reinvested rather than paying it out. Interest in the next period is then earned on the principal sum plus previously accumulated interest.
The formula is:
[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]
Where:
A = final amount
P = initial principal balance
r = interest rate
n = number of times interest applied per time period
t = number of time periods elapsed
Abdul deposited P=$4000 into an account with r=2.6% = 0.026 compounded quarterly. Since there are 4 quarters in a year, n=4. We are required to calculate the amount in the account after t=10 years.
Applying the formula:
[tex]{\displaystyle A=4000\left(1+{\frac {0.026}{4}}\right)^{4*10}}[/tex]
[tex]{\displaystyle A=4000\left(1.0065\right)^{40}}[/tex]
A = $5183.36

Use the Discriminant to find the number and type of solutions to x^2 + 6x -5 = 4x^2
A 2 Real Solutions
B 1 Real Solution
C Real Solutions, 2 Imaginary Solutions
D 3 Solution
Answer:
The equation [tex]x^2 + 6x -5 = 4x^2[/tex] have 2 non-real solution, 2 imaginary solutions.
Step-by-step explanation:
Using the Discriminant to find the number and type of solutions to [tex]x^2 + 6x -5 = 4x^2\\x^2-4x^2+6x-5=0\\-3x^2+6x-5=0[/tex]
The discriminant is: [tex]b^2-4ac[/tex]
We have a = -3, b=6 and c=-5
Putting values and finding discriminant
[tex]b^2-4ac\\=(6)^2-4(-3)(-5)\\=36-60\\=-24\\[/tex]
So, we get discriminant = -24
if discriminant < 0 the solution will have two non-real imaginary solutions.
In our case discriminant < 0 i,e discriminant = -24
So, The equation [tex]x^2 + 6x -5 = 4x^2[/tex] have 2 non-real solution, 2 imaginary solutions.
Harry earned d dollars mowing lawns. He put 20% of his earnings in the bank and paid back $50.00 to his father. He spent
one-fifth of the remaining money on a video game. Which expression represents the amount he spent on the video game?
(0.20 - 10) dollars
(0.20 - 50) dollars
(0.160 + 10) dollars
(0.160 - 10) dollars
Answer:
(0.16d - 10) dollars
Step-by-step explanation:
"Harry earned d dollars mowing lawns. He put 20% of his earnings in the bank and paid back $50.00 to his father."
Start with d dollars.
He put 20% of d dollars in the bank. 20% of d is the same as 0.2d.
Now he has d - 0.2d = 0.8d
He paid his father $50.
Now he has 0.8d - 50
"He spent one-fifth of the remaining money on a video game. Which expression represents the amount he spent on the video game?"
He spent 1/5 of 0.8d - 50 on a video game, so he spent on the video game:
1/5 * (0.8d - 50) = 0.16d - 10
Answer: 0.16d - 10 dollars
(You forgot the "d" in the answers."
(0.16d - 10) dollars

Answer:
Area of rectangular garden = lxb = 10*5
= 50 sq. inch
when area increases by six times
new area = 50*6 = 300 sq inches
now,
let x be increasement in both length and width
(5+x) (10+x) = 300
50 + 5x + 10x + x² = 300
x² + 15x - 250 = 0
x²+ 25x-10x -250 = 0
x(x+25) - 10 (x+25) = 0
( x-10) (x+25) = 0
either x + 25 =0
x = -25 length can be negative
0r x-10 = 0
x = 10
so 10 inches is increase on both side
