Answer:
y=Q+3D
Step-by-step explanation:
the total amount is y=, than A would be quarters. and you add 3 because there's always 3 more dimes than quarters than add D for dimes.
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
You have $3.10 in dimes and quarters. You have 3 more dimes than quarters.
Let 'x' be the number of dimes and 'y' be the number of quarters. Then the equation is given as,
0.10x + 0.25y = 3.10 ...1
x = y + 3 ...2
From equations 1 and 2, then we have
0.10(y + 3) + 0.25y = 3.10
0.10y + 0.30 + 0.25y = 3.10
0.35y = 2.8
y = 8
Then the value of 'x' is given as,
x = 8 + 3
x = 11
The system of equations is 0.10x + 0.25y = 3.10 and x = y + 3. The number of dimes and quarters will be 11 and 8, respectively.

Which function has a removable discontinuity at x = 7?
9514 1404 393
Answer:
(b) see below
Step-by-step explanation:
A removable discontinuity exists when the function is undefined at a point where the limit exists.
Choices A, C, D have no limit at x=7 (does not exist).
__
Choice B can be simplified to ...
f(x) = (x -3)(x -7)/(x -7)
f(x) = (x -3) . . . . . . . x ≠ 7 (domain restriction; undefined at x = 7)
The discontinuity in this function can be removed by defining the function to be f(x) = x-3 everywhere.

B

The bases of a cylinder have a diameter of 4 inches. The height of the cylinder is 6 inches. What is the total surface area of the cylinder?
Answer:
Step-by-step explanation:
area of base = π4² = 16π in²
lateral area = 2πrh = 2π·4·6 = 48π in²
surface area = 2×16π + 48π = 80π in² ≅ 251.3 in²
Answer: 100.54 in^2
Step-by-step explanation:
(the area of a circle*2) + (the circumference*the height) = the surface area of the circle
Area of a circle: Pi*r^2
Circumference: 2*Pi*r

Asif would pay $2400 for a jacket if the price was reduced by 40% what is the the original price of the jacket
Answer: $4,000
Step-by-step explanation:
If the price of the jacket is reduced by 40%, it ends up being $2,400.
Assuming the original price is x, the expression will be:
x - (40% * x) = 2,400
x - 0.4x = 2,400
0.6x = 2,400
x = 2,400 / 0.6
x = $4,000

george has opened a new store and he is monitoring its success closely. He has found that this store’s revenue each month can be modeled by r(x)=x2+5x+14 where x represents the number of months since the store opens the doors and r(x) is measured in hundreds of dollars. He has also found that his expenses each month can be modeled by c(x)=x^2−4x+5 where x represents the number of months the store has been open and c(x) is measured in hundreds of dollars.
the new store will sell 900 items in its fifth month in business
the store will have a profit of $900 after its fifth month in business
the store will have a profit of $5400 after its fifth month in business
the new store will sell 5400 items in its fifth month in business
Answer:
Step-by-step explanation:
The correct answer is that the new store will have a profit of $5400 after its fifth month.
Profit is given by subtracting revenue minus cost:
(R-C)(x) = (x²+5x+14)-(x²-4x+5) = x²-x²+5x--4x+14-5 = 5x+4x+14-5=9x+9
Using 5 for x,
(R-C)(5) = 9(5) + 9 = 45+9 = 54
This is in hundreds of dollars, so it represents $5400.
Evaluate the expression, 7x+8(x-3). Assume that x=4.
