Answer:
It would last for 3.2 days.
Step-by-step explanation:
100 men = 8 days
10 men = 0.8 days
60 men = 0.8 x 6 = 4.8 days
Now you subtract the days of 100 men and 60 men
8 - 4.8 = 3.2 days

Help plsssss!!!!! Question below!!!
Two wizards make boxes with secret compartments to sell at the magic convention. Fred plans to make 160 boxes by the start of the convention. Georgiana plans to make 25% fewer in the same amount of time. Fred makes 10 more boxes each day than Georgiana, and finishes his job 2 days before the convention. How many boxes does Georgiana make each day if she needs two extra days after the convention starts to complete her job?
Answer:
10
Step-by-step explanation:
No i dont think I wil
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 jar contains nickels and dimes. There is a total of 25 coins in the jar. The value of the coins is $1.75. How many nickels and how many dimes are in the jar?
Answer:
15 nickels and 10 dimesStep-by-step explanation:
Dimes - d, dime = 10c, total dimes = 10dNickels - n, nickel = 5 c, total nickels = 5n$1.75 = 175 cEquations:
d + n = 2510d + 5n = 175Multiply the first equation by 5 and subtract from the second one:
10d + 5n - 5d - 5n = 175 - 1255d = 50d = 10Find n:
n = 25 - d = 25 - 10 = 15A company makes muesli which contains nuts and sultanas.

To Find :
complete the table
calculate and estimate for the mean
The estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.
a) To complete the table, we need to find the values of "fx" (frequency multiplied by the midpoint) for each class interval. Here's the updated table:
Number of Nuts Number of Packets Midpoint (x) fx
4-6 5 5 5 * 3 = 15
7-9 8 8 8 * 9 = 72
10 - 12 11 11 11 * 12 = 132
13 - 15 14 14 14 * 17 = 238
16 - 18 17 17 17 * 9 = 153
Total 50 610
b) To calculate an estimate for the mean, we use the formula:
Mean = Sum of (fx) / Total Number of Packets
Mean = 610 / 50
Mean ≈ 12.2
Therefore, the estimate for the mean number of nuts in a serving packet of muesli is approximately 12.2 nuts.

The points (1, 10) and (0, 2) fall on a particular line. What is its equation in slope-
intercept form?
0) Write your answer using integers, proper fractions, and improper fractions in simplest
form.
y = x +
Answer:
y = 8x + 2
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Here, m = slope of the line
b = y-intercept
Since, slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By this formula, slope of a line passing through (1, 10) and (0, 2) will be,
m = [tex]\frac{10-2}{1-0}[/tex]
m = 8
Equation of the line will be,
y = 8x + b
Since, this line passes through (0, 2),
2 = 8(0) + b
b = 2
Therefore, equation of the line will be,
y = 8x + 2
Answer:
y=3x+2

Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio. A (-5, 12) B (11, 0) 1 :3
Answer:
(7, 3)
Step-by-step explanation:
Using the midpoint formula
M(X, Y) = {(ax1+bx2/a+b), ay1+by2/a+b}
X = ax1+bx2/a+b
X = -5(1)+3(11)/1+3
X = -5+33/4
X = 28/4
X = 7
Y = ay1+by2/a+b
Y = 1(12)+3(0)/1+3
Y = 12/4
Y = 3
Hence the coordinate of P is at (7, 3)
A parallelogram has an area of 20 square centimeters. The height of the triangle is 5 centimeters. What is the length of its base?
Answer:
4 cm
Step-by-step explanation:
A parallelogram area formula= Base x Height.
It already gave you the area so you can work backwards to solve for the base.
So, 20 divided by 5(the height) is 4.
Therefore, you can conclude that the length of the base is 4 cm.

Gravity pulls the metal down at 10 N, but the metal pieces RISES! At least how much force is needed to make it move upward?
Answer: Greater than 10 N
Step-by-step explanation:
Given
Gravity force on metal is 10 N
But the metal piece is rising i.e. there must be an upward force greater than 10 N
Suppose the force is F
So, we can write
[tex]\Rightarrow F>10\ N[/tex]
Any force greater than 10 N is sufficient for the metal to move upwards
The greater the amount of force faster will be the movement
The shorter leg of a right triangle is two less than the hypotenuse. The longer leg is one less than the hypotenuse. Find all three sides of the triangle. HELP TEST!
Answer:
x = 5
Step-by-step explanation:
using the Pythagorean theorem:
(x-1)² + (x-2)² = x²
x²-2x+1 + x²-4x+4 = x²
reduce:
2x²-6x+5 = x²
subtract x² from each side:
x²-6x+5 = 0
(x-1)(x-5) = 0
x=1 but because shorter leg would be 0, a triangle would be impossible.

Yesterday 56 people came to the Center, How many people came to the Center to hike if: 30 people took classes,22 went bird-watching, and l2 people did both?
Answer:
40 people came to the Center to hike
Step-by-step explanation:
30 people took classes
22 did bird watching
12 did both
to solve, take 12 and subtract it from each one:
⇒ 30 - 12 = 18
⇒ 22 - 12 = 10
18 people only took classes
10 people only did bird watching
12 people did both
18 + 10 + 12 = 40
