How many 14s make 3?
Answer:
12 1/4's make 3.
12 × 1/4 = 3
Step-by-step explanation:
Dividing by a fraction is the same thing as multiplying by its reciprocal.
Skip the first number, Flip the fraction, and Multiply them.
\(3 \div \dfrac{1}{4}\)
\(= 3 \times \dfrac{4}{1}\)
\(= 3 \times 4\)
\(= 12\)
Jenny has pennies, nickels, dimes, quarters, half-dollars, and/or dollar coins in her purse. Still, she's unable to make change for an old $2 bill. What is the greatest amount of money that she could possibly have? (She may have none of the same coins.)
Answer:
The Only Possible Max amount is $1.99
Step-by-step explanation:
If she has change and doesnt have enough for a two dollar bill then we use common sense,
$1 = 100 cents
$2 = 200 cents but she cant get 2 dollars so we subtract 1 cent from 200 cents and end up with 199 cents which is 1 dollar 99 cents
PLS HELP!!!!!
Brayden conducted a scientific experiment. For a certain time, the temperature of a compound rose 2 2/5 degrees in 1/5 of an hour. How much did the temperature of the compound rise in one hour?
Answer: 12 degrees or 11 5/5 or 60/5
Step-by-step explanation:
Since the temperature is rising 2 2/5 per 1/5 of an hour we just need to multiply 2 2/5 times 5 because 5/5 would equal the whole hour. In order to multiply easier you can change 2 2/5 to an improper fraction by multiplying the whole number with the denominator and then adding the numerator. Which you should get 12/5 next change 5 to a fraction which would be 5/1. 5 times 12 is 60 and 5 times 1 is 5. You get 60/5 which if divided is 12.
For the number line you just have to find 1/5 and 2 2/5 on it and mark it.

A plumber charges $25 for a service call plus $50 per hour of service. Write an equation in slope-intercept form (y = mx + b) for the cost, C, after h hours of service.
Answer:
C = 50H + 25
Step-by-step explanation:
The starting fee is $25, which means that you must add $25 no matter what.
The plumber is charging $50 dollars per hour, so it should be 50H

From a log of wood of length (8x+12) m, a piece of length (4x+3) m was cut. Find the length of the remaining log of wood.
Grade#7
Answer: 4x+9
Step-by-step explanation: (8x+12)- (4x+3)
Answer: (4x+9)
Step-by-step explanation:
Log of wood = (8x+12)
piece length = (4x+3)
So, (8x+12) - (4x+3)
=> (8x+12) - 4x - 3
=> 8x-4x +12 -3
=> 4x + 9
So, the length of the remaining piece of wood = (4x+9)
hope it helps

Solve the inequality.
10−12x<−18
Which inequality represents the solution to this inequality?
PLEASE HELP!!!
Responses
x>−56
x>−56
x<56
x<56
x>56
x>56
x<−56
x<−56
Answer: x> 2.33
None of the answer choices listed are correct.
Step-by-step explanation:
The inequality can be solved by adding 12x to both sides and then subtracting 10 from both sides:
10 - 12x + 12x < -18 + 12x
10 < -18 + 12x
Now we subtract -18 from both sides:
10 - (-18) < -18 + 12x - (-18)
28 < 12x
Finally, we divide both sides by 12:
28/12 < 12x/12
2.33 < x
So, the solution to the inequality 10 - 12x < -18 is x > 2.33.

Answer: Surface Area = 2 x (5x2 + 3x2 + 5x3) = 62 centimeters
Surface area of a right rectangular prism = 2(lh + wh + lw)
Step 1: Label the Given-
Length (l) = 5cm, Width (w) = 3cm, Height (h) = 2cm
Step 2: Replace the given-
Surface Area = 2 x (5x2 + 3x2 + 5x3)
= 2 x (31)
Surface Area = 62 centimeters
Horus got his answer, by applying only what lays inside the parentheses. To get the right answer, Horus must multiply what they got by 2:
2 x (31) = 62 centimeters
Answer:
SA= 15+6+10+10+15+6 = 62
Step-by-step explanation:
take your top rectangle multiply length and width= 15
Take the one right below it take the 2cm, and multiply it with 3=6
after that one doe 3x5 again=15
Then, 3x2=6
And then 5x2=10
And then once more=10
Set up and solve a system of equations to solve the problem.
A jar contains n nickels and d dimes. There are 20 coins in the jar, and the total value of the coins is $1.50. How many nickels and how many dimes are in the jar?
The jar contains ___ nickels and ___ dimes.
Answer:
The jar contains 10 nickels and 10 dimes. Another answer is that the jar contains 4 nickels and 13 dimes.
Step-by-step explanation:
1 nickels = 5 cents
1 dime = 10 cents
1st answer
10 nickels = $0.50
10 dimes = $1.00
So 10 nickels + 10 dimes = $1.50
2nd answer
13 dimes = $1.30
4 nickels = $0.20
So 13 dimes + 4 nickels = $1.50

the volume of the right circular cylinder in 144π cubic yards. if h, the height of the cylinder is 4 yards, what is r, the radius of the base?
Answer:
r = 6
Step-by-step explanation:
The formula for the volume of a cylinder is V = πr^2h,
If the volume of the cylinder is 144π cubic yards and the height of the cylinder is 4 yards it can be written as 144π = πr^2 * 4
You can then solve for r by dividing both sides of the equation by 4π:
r^2 = 36
r = 6

Area of Composed Figures.
Answer:
3
Step-by-step explanation:
Just uhh… it’s a lot, I’ll try to do this by myself.
Answer:
\(\textsf{(a)} \quad -2x-4\)
\(\textsf{(b)} \quad 2x+5\)
(c) Not equivalent.
\(\textsf{(d)} \quad 3x^2-24x+48\)
\(\textsf{(e)} \quad 9x^2-72x+144\)
(f) Not equivalent.
Step-by-step explanation:
Equivalent expressions are expressions that simplify to the same expression.
Part (a)
\(\begin{aligned}&\textsf{Add 3 to $x$}: & \quad x+3\\&\textsf{Subtract the result from $1$}: & \quad 1-(x+3)\\&\textsf{Double}: & \quad 2[1-(x+3)]\\&\textsf{Expand}: & \quad 2[1-x-3]\\&\textsf{Simplify}:&2[-x-2]\\&& -2x-4\end{aligned}\)
Part (b)
\(\begin{aligned}&\textsf{Add 3 to $x$}: & \quad x+3\\&\textsf{Double}: & \quad 2(x+3)\\&\textsf{Subtract $1$ from the result}: & \quad 2(x+3)-1\\&\textsf{Expand}: & 2x+6-1\\&\textsf{Simplify}:&2x+5\end{aligned}\)
Part (c)
The expressions are not equivalent.
The coefficients of the x-variables are the negatives of one another, and the constants are different numbers.
Part (d)
\(\begin{aligned}&\textsf{Subtract 4 from $x$}: & \quad x-4\\&\textsf{Square the result}: & \quad (x-4)^2\\&\textsf{Triple}: & \quad 3(x-4)^2\\&\textsf{Expand}: & \quad 3(x^2-8x+16)\\&\textsf{Simplify}:& 3x^2-24x+48\end{aligned}\)
Part (e)
\(\begin{aligned}&\textsf{Subtract 4 from $x$}: & \quad x-4\\&\textsf{Triple the result}: & \quad 3(x-4)\\&\textsf{Square}: & \quad [3(x-4)]^2\\&\textsf{Expand}: & \quad [3x-12]^2\\&\textsf{Simplify}:& 9x^2-72x+144\end{aligned}\)
Part (f)
The expressions are not equivalent.
The coefficients the second equation are three times the coefficients of the first equation.
