A project will take a total of 720 person-days to complete. If the project must be completed in 30 days, how many people must be employed? PLEASE HURRY
Answer:
192 hours per day / 8 hours per person per day = 24 people
Step-by-step explanation:
Assuming each person works for 8 hours a day, the total number of hours needed to complete the project is:
720 person-days x 8 hours = 5,760 hours
To complete the project in 30 days, the total number of hours needed per day is:
5,760 hours / 30 days = 192 hours per day

Step-by-step explanation:
because i pay attention in math class
The equation y = x has the positive slope.
What is Slope?Slope of a line is the ratio of the change in y coordinates to the change in the x coordinates of two points given.
Slope can also be defined as the tangent of the angle that the line is making with the positive X axis.
Given three equations which are in the form of slope intercept form of the equation of a line.
Slope intercept form of a line is y = mx + d, where m is the value of the slope and d is the value of the y intercept.
y intercept is the y coordinate of the point on the line where it touches the Y axis. The x coordinate will be 0 there.
Equations given are
y = -x + 0 ⇒ Slope = -1
y = x ⇒ Slope = 1
y = -4 ⇒ Slope = 0
So y = x has the slope equal to 1 which is positive.
Hence the equation y = x has the positive slope.

At a restaurant, Trevor decides to tip the server 16% of the bill. If he leaves a $4.00 tip, which proportion could be used to find how much the bill was for?
16/100 = x/4
16/100 = 4/x
4/100 = x/16
4/100 = 16/x
The answer is: 16/100 =4/x
16 divided by 100 is 0.16
And 4x4 is 16
x is the varible of how much so it goes 4/x
So your answer is 16/100 =4/x

Nellie just bought a new perfume called Rose Honey. It comes in a bottle shaped like a rectangular prism. The bottle is 4 centimeters long, 2 centimeters wide, and 7 centimeters tall, but the perfume's box says the bottle only contains 45 milliliters, or 45 cubic centimeters, of perfume.
How many more milliliters of perfume would it take to completely fill the bottle?
Write your answer as a whole number or decimal. Do not round.
Answer:
It would take 11 milliliters of perfume to completely fill the bottle.
Step-by-step explanation:
The volume of the rectangular prism-shaped bottle can be calculated by multiplying its length, width, and height. Therefore, the bottle's volume is:
4 cm x 2 cm x 7 cm = 56 cubic centimeters
The bottle contains 45 cubic centimeters of perfume, so the amount of additional perfume needed to completely fill the bottle is:
56 cubic centimeters - 45 cubic centimeters = 11 cubic centimeters
Therefore, it would take 11 more milliliters of perfume to completely fill the bottle. Since 1 cubic centimeter is equal to 1 milliliter, the answer is simply 11 milliliters.
7 times 2 times 4 - 45
56-45= 11

a. Use an inequality to find the number of monthly calls for which Plan 1 is more economical than Plan 2.
b. Explain the meaning of the answer to part a.
Answer:
Step-by-step explanation:
wouldn't you do 29 x 19=551+0.05=551.05
Answer:
The number of monthly calls for which Plan 1 is more economical than Plan 2 is 200 calls If more than 200 calls are made, the plan 1 charge will be more than plan 2. Let the number of charges per month be x If plan 2 charges $16 per month plus $0.04 per call, this is expressed as 0.04x + 16 Price that pan 1 charges = $24 If Plan 1 is more economical than Plan 2, this is expressed as:0.04x + 16 > 24 Subtract 16 from both sides:0.04x + 16 - 16 > 24 - 16 0.04x > 8 x = 6/0.04 x = 200 This shows that if more than 200 calls are made, the plan 1 charge will be more than plan 2.

Antonio graphs these equations and finds that the lines intersect at a single point, (-5,0.25)
Answer:
Answer C.
Step-by-step explanation:
If x= -5 and y= 0.25
Equation A : 4 * 0.25 - 3 * -5 = 16
Equation B: -(-5) -8*0.25=3
These are only coordinates that satisfy the equation.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given coordinates: (-5, 0.25)
Equation A: 4y - 3x= 16
So, 4(0.25)- 3 (-5)
= 1+ 15
= 16
and, Equation B: -x -8y= 3
So, -(-5) -8 (0.25)
= 5 - 2
= 3
Hence, these are only coordinates that satisfy the equation.

Answer:
first things first. a polygon is a shape that has more than 3-4 sides. i am pretty sure that the first two are polygons because it has multiple sides without any curves the last image is an octagon becasue it has 8 sides. and it is an regular polygon. oct means 8
Step-by-step explanation:
-So, the first shape is defined as a polygon because of the points. It is closed, with straight sides.
-The next figure is not a polygon at all because there is a break in the figure.
-And for number 3, the regular shape to be considered a polygon is a square. A square is one of the more popular shapes and is exact on the length of sides and has perfect turns in the angles.
