Fred finishes his job 2 days before and makes 10 boxes than Georgiana
each day, the number of boxes Georgiana makes each day are 10 boxes.
Which method can be used to find the boxes made?The number of boxes Fred plans to make = 160 boxes
Number of boxes Georgiana plans to make = 25% fewer than Fred
Number of boxes Fred makes each day = 10 more than the number of boxes Georgina makes
Number of days before the convention Fred finishes his job = 2 days before the convention
Number of days after the convention Georgina completes her job = 2 days after the convention starts
Let x represent the number of boxes Fred makes per day and let y
represent the number it takes Fred to complete his job, we have the
following equations;
x × y = 160
(x - 10) × (y + 4) = 0.75 × 160 = 120
Which gives;
[tex]\mathbf{(x - 10) \times \left(\dfrac{160}{x} +4 \right)} = 120[/tex]
4·x² + 120·x - 1600 = 120·x
4·x² + 120·x - 120·x = 1600
4·x² = 1600
x = √(1600 ÷ 4) = 20
The number of boxes Fred makes each day, x = 20 boxes
Number of days Fred takes, y = 160 ÷ 20 = 8
The number of boxes Georgina makes each day = 20 - 10 = 10Learn more about equations here:

A player shoots a basketball from a height of 6 feet. The equation, h = -16t^2 + 25t + 6, gives the height, h , of the basketball after t seconds. Describe the height, rounded to the nearest tenth of a foot, of the basketball after 1.5 seconds, assuming no other player touches the ball.
Answer:
[tex]\boxed {\boxed {\sf 7.5 \ feet}}[/tex]
Step-by-step explanation:
We are given this function for the height (h) after t seconds:
[tex]h=-16t^2+25t+6[/tex]
Seconds is t and we want to find the height after 1.5 seconds. Plug 1.5 in for t.
[tex]h= -16(1.5)^2+25(1.5)+6[/tex]
Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.
Solve the exponent first.
(1.5)²= 1.5*1.5=2.25[tex]h= -16(2.25)+25(1.5)+6[/tex]
Multiply.
[tex]h= -36+25(1.5)+6[/tex]
[tex]h= -36+37.5+6[/tex]
Add.
[tex]h=1.5+6=7.5[/tex]
This is already rounded to the nearest tenth, so it is the answer.
After 1.5 seconds, the basketball is at a height of 7.5 feet.

The Martinez Family has driven 240 miles so far. Their total trip is 300 miles. What percentage of the trip have they already driven?
Answer:
80%
Step-by-step explanation:
Percentage of the trip covered = [tex]\frac{miles driven }{total miles}[/tex] × 100
I am multiplying by 100 because to convert to percentage, we have to multiply by 100
Miles drive = 240
Total miles = 300
[tex]\frac{240}{300}[/tex] × 100 = 80%

If 2 = 6, what is the degree measure of 5?
A. 80
B. 220°
C. 60°
D. 120°
Answer:
60°
Step-by-step explanation:
We know that 2 and 6 = 60 degrees, so we add 60 + 60 which equals 120, now subtract 120 by 180 and you get 60 degrees.

-11n < -9n + 8
-2n < 8
n > -4
Answer:
n>-4
Step-by-step explanation:
Let's solve your inequality step-by-step.
−5n−6n<8−8n−n
Step 1: Simplify both sides of the inequality.
−11n<−9n+8
Step 2: Add 9n to both sides.
−11n+9n<−9n+8+9n
−2n<8
Step 3: Divide both sides by -2.

What is the slope of the line that passes through M(-6, 1) and N(2, 5)?
Answer:
m = 1/2
Step-by-step explanation:
As we move from M to N, the x-coordinate increases from -6 to 2, a jump ('run') of 8 units. Likewise, the y-coordinate increases from 1 to 5, a jump of 4 units. The slope of the line passing through these two points is thus
m = rise / run = 4/8 = 1/2

a store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 6 pounds of jelly beans, the total cost is $23. For 3 pounds of trail kix and 2 pounds of jelly beans, the total cost is $11. Find the cost for each pound of traol mix and each pound of jelly beans
Answer:
j=$1.75/lb
t=$2.5/lb
Step-by-step explanation:
(1) 5t+6j=23
(2) 3t+2j=11, t=11/3 - 2j/3
sub t into (1):
5(11/3 - 2j/3) +6j = 23
55/3 -10j/3 +6j =23
8j/3=14/3
8j=14
j=7/4
sub j into t:
t=11/3 -2(7/4)/3
t=5/2

n + 13 = 52
Answer:
N = 39
Step-by-step explanation:
N + 13 = 52
-13. -13
N = 39
Answer:
n = 39
Step-by-step explanation:
To find what n equals, I want to get it alone on one side of the equation.
To do this, I move 13 to the right side of the equation by subtracting 13 from both sides.
13-13=0 so n is the only value on the left side
52-13=39.
You are now left with n = 39
To check that this is right, add 13 to 39. It equals 52, so you know the answer you found is correct.
