Answer:

D) 90 Days

Step-by-step explanation:

dredge 1 min = 3 people days

when I say people days, I mean 3 people working one day

multiply each side by 60 to get the desired 60 min of dredge:

dredge 60 min = 180 people days

As we currently have this set up, it will take 180 people, 1 day to do the same amount of work as 60 min of dredge, but we only want 2 people.  This means we need to divide the people days by 2 to get how many days are needed for 2 people, thus:

dredge 60 min = 2 people for 90 days

Answer:

(4, -3)

Step-by-step explanation:

Since we know that X = 4, when can set X = 4 in the other equation in order to solve for Y

2x - 4y = 20

2(4) - 4y = 20

8 - 4y = 20

-8           -8

-4y = 12

-4y/-4 = 12/-4

y = -3

Since we already know X = 4, the intersection point or solution to the System is (4, -3)

Hope this helps!

Answer:

71

Step-by-step explanation:

If a decimal needs to be rounded to a whole number, you need to refer to the tenths place in the decimal. In this case, that is "5" and in math, when rounding, if it is 5 or more, you round up to the next whole number. If it is 4 or less, you round down. So 70.5 rounded to the nearest whole number is 71. :)

Answer:

Simplifying

Y = 2x + -1

Reorder the terms:

Y = -1 + 2x

Solving

Y = -1 + 2x

Solving for variable 'Y'.

Move all terms containing Y to the left, all other terms to the right.

Answer:

[tex]m = \frac{-1}{6}[/tex]

Step-by-step explanation:

You are solving for the slope (m). Use the following equation:

slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]

Let:

[tex](x_1 , y_1) =(-2 , 1)\\(x_2 , y_2) = (4 , 0)[/tex]

Plug in the corresponding numbers to the corresponding terms:

m = [tex]\frac{0 - 1}{4 - (-2)}[/tex]

[tex]m = \frac{-1}{4 + 2} \\m = \frac{-1}{6}[/tex]

[tex]m = \frac{-1}{6}[/tex] is your answer.

Answer:

22 83/100

Step-by-step explanation:

22 is a whole number, while .8333 is continues you have to round it to .83. .83 is in the hundredths place so it would be 83/110. So in the end you'll have 22 83/100

Answer: I’m assuming this is supposed to repeat because that’s ridiculous if it isn’t. The answer is 22 5/6

Answer:

neither, would technically be intersecting lines tho

Step-by-step explanation:

You plot the points on the graph first with a pencil. Draw the given line, in this case, it's y=-x.

From a point, you do rise and run to the line and reverse it on the other side of the line to get the points.

Refer the attached diagram, for easy method.

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

1) Three points are not in the same plane if and only if exactly one line passes through them.

It is biconditional and false because more than one plane can pass through three points

2)Exactly one line passes through three points if the points are in an infinite number of planes.

It is biconditional and true because three points on same line will be in more than one plane and if they are not in the same plane then connect them and it will form a triangle which is in only one plane

3). an infinite number of planes pass through the same three points if and only if the points are not on the same line.

It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

4). three points on the same line if and only if exactly one plane passes through them. ​

It is biconditional and false because more than one plane passes through them So, infinite no. of planes passes through them

Answer:

The slope of the model is [tex]m = 2\,\frac{USD}{yr}[/tex].

The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.

Step-by-step explanation:

We have to notice that given function is a linear function, that is, a first order polynomial, whose standard form is described below:

[tex]y =m\cdot x + b[/tex]

Where:

[tex]m[/tex] - Slope, dimensionless.

[tex]x[/tex] - Independent variable, dimensionless.

[tex]y[/tex] - Dependent variable, dimensionless.

[tex]b[/tex] - y-Intercept, dimensionless.

In this case, we use the linear function [tex]y = 2\cdot x + 28[/tex], where [tex]x[/tex] is the time after 2000, measured in years, and [tex]y[/tex] is the average cost of a hair cut. The slope of the model is [tex]m = 2\,\frac{USD}{yr}[/tex].

The value of the slope indicates that the average cost of a hair cut is increased by 2 US dollars each year.

Answer:

0.52grams of dissolved solids.

Step-by-step explanation:

; a 50-milliliter water sample has just 13 milligrams of dissolved solids. If Ernesto fills a 2-liter bottle from one of the water fountains at his school, how many grams of dissolved solids would his bottle have

50ml = 13mg of dissolved solids

1 litre = 1000 millilitres

2 liter = 2 × 1000 = 2000millilitres

50ml = 13mg

2000ml =

Cross Multiply

2000ml × 13m/50ml

= 520mg of dissolved solids.

We are to convert our final answer to grams

= 1 milligram = 0.001 gram

520 milligram =

520 mg × 0.001g/1 mg

= 0.52 grams of dissolved solids

Answer: 4

Step-by-step explanation:

Follow the PEMDAS so the first thing you do is 14:7 which is 2. then you do the division and multiplication so the 44:11 is 4, 5*2 is 10, and 2*2 is 4. The next thing you do is addition and subtraction. 26-4-4-10-4 is 4. So, the answer is 4.

Answer:

You cant see the equation

Step-by-step explanation:

Answer:

56.52mm²

Step-by-step explanation:

Based on observation, sum of diameters of small circles = diameter of the big circle.

In question, diameter of big circle = 12 mm.

And radius of big circle = 12mm/2 = 6mm

Let the diameter of each small circle be '2a'. So, radius of each small = 2a/2 = a.

=> 2a + 2a = 12mm

=> 4a = 12mm

=> a = 3mm

=> radius of each small circle = 3mm

Area of big circle = πr²

= (3.14)(6mm)²

= 113.04 mm²

Area covered by 2 small circles is: 2 * area of 1 one circle.

=> 2 * π(3mm)² = 18π mm²

=> 56.52 mm²

Shaded area = total area - area of 2 circles = 113.04 - 56.52 mm² = 56.52 mm²
