A map of Colorado says that the scale is 1 inch to 20 miles or 1 to 1,267,200. Are these two ways of reporting the scale the same? Explain your reasoning.

Answers

Answer:

1,267,200

Step-by-step explanation:

Given that the map reported that the scale is 1 inch to 20 miles.

Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200

Therefore, the scale of 1 inch to 20 miles can also be represented as 1 to 1,267,200

Prove that if -5(x + 4) = 70, the x = -18. Write a justification for each step.

Answers

Step-by-step explanation:

Let's solve your equation step-by-step.

−5(x+4)=70

Step 1: Simplify both sides of the equation.

−5(x+4)=70

(−5)(x)+(−5)(4)=70(Distribute)

−5x+−20=70

−5x−20=70

Step 2: Add 20 to both sides.

−5x−20+20=70+20

−5x=90

Step 3: Divide both sides by -5.

−5x

You operate a fresh fruit and vegetable market. For normal shipments, about 9.0% of the peaches are spoiled when they reached your market. You anticipate a busy weekend and would like to have 100 pounds of peaches to sell. To have 100 pounds of peaches and considering the spoilage rate, how many pounds should you order?

Answers

Answer:

110 pounds of peaches should be ordered

Step-by-step explanation:

Here, we want to calculate the number of pounds of peaches to order.

Let the number of peaches to ordered be x peaches

Now, since 9% is expected to be bad, then the percentage expected to be good will be 91%

Thus;

91% of x = 100

91/100 * x = 100

91x = 100 * 100

x = 10000/91

x = 109.89

Since we cannot have fractional peaches, then x must be 110

In training for a swim meet, Logan swam 750 meters in 1.3 of a hour. His swimming partner , Mila swam 2.3 of Logan's distance in 1.4 of a hour. What is Logan's average swimming speed? What is Mila's average swimming speed? Compare Mila's and Logan's swimming speed.

Answers

Answer:

Step-by-step explanation:

For Logan:

Logan swam 750m

Logan distance = 750m

Time taken = 1.3×3600

Time taken = 4680

Logan average speed = distance/time

average speed = 750/4680

Logan Average speed = 0.160m/s

Mila swam 2.3 of Logan's distance

Milan distance = 1725m

Time taken = 1.4×3600

Time taken = 5040s

Milan average speed = distance/time

Milan average speed = 1725/5040

Milan average speed = 0.342m/s

Comparing Milan speed with Logan speed:

Difference in speed = 0.342-0.160

Difference in speed = 0.182m/s

This means that Milan speed is 0.182 greater than Logan speed.

Point slope question

Answers

Answer: (y + 3) = -1/3 (x - 2)

Step-by-step explanation:

Point-slope form has the form of

y - y1 = m (x - x1)

Where

y1 is the y-value of a point on the line

x1 is the x-value of a point on the line

m is the slope of the line

The problem already gives a point on the line, (2, -3)

(y + 3) = m (x - 2)

Remember to put the opposite value of the x and y values. (In other words, do NOT write (y - 3) = m (x + 2) )

The slope of a perpendicular line is the opposite reciprocal of slope of the line it is perpendicular to. The perpendicular line given in the equation is

3x - y = 4

When rearranged to slope-intercept form, we get

y = 3x - 4

Meaning the slope of the perpendicular line is 3. The opposite reciprocal of positive three is negative one-third. Therefore, the slope of the line we are solving for is -1/3.

A square has an area of 9yd^2. What is the length of each side?

Answers

Answer: The side length is 3 yards.

Step-by-step explanation:

To find the area of a square, you have to square one of it's side lengths since they all share the same length.  Since we know the area, and we need to find the side length so we just need to find the square root of the area.

[tex]\sqrt{9}[/tex] = 3    

The side length is 3 yards.

The length of each side of a square is, 3 yards.

What is mean by Rectangle?

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

We have to given that;

⇒ An area of square = 9 yards²

Now, We know that;

⇒ Area of square = Side²

Let the side of square = a

So, We get;

⇒ a² = 9

⇒ a = √ 9

⇒ a = 3 yards
