if a circle's circumference is 15 inches what is its radious? leave the symbol pi in your answer ​

Answers

Answer 1

Answer:

the radius is 2.38

Step-by-step explanation:

use the formula c=2pi r

Answer 2

Answer:

15/2π

Step-by-step explanation:

If the circumference is 15 inches, we can create an equation using the following formula:

Circumference of circle = 2 x π x radius

which is C = 2πr

Now, substituting our value of the circumference (15) into the equation, we get:

15 = 2πr

In order to find r, the radius, we must divide both sides by 2π, which makes r the subject. This cancels out the 2π on the right side, leaving us with:

15/2π = r

So the radius is 15/2π.

Write the equation of the line, with the given properties, in slope intercept form slope = -2, through(-4,7)

Answers

Answer:

y= -2x + 7

Step-by-step explanation:

So in slope intercept y will always equal something so you start with

y= mx + b

m = slope and b = y-intercept

so in this case it would first be

y = -2x + b

and then since we have the point it passes through (-4,7) we know that the line passes through the y axis at 7 hence the y value is 7.

so you finally get

y=-2x+7

The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

The point on the line are (-4, 7).

And, The slope of the line is,

⇒ m = - 2

Now,

Since, The equation of line passes through the point (- 4, 7).

And, Slope of the line is,

m = - 2

Thus, The equation of line with slope - 2 is,

⇒ y - 7 = - 2 (x - (-4))

⇒ y - 7 = - 2 (x + 4)

⇒ y - 7 = - 2x - 8

⇒ y = - 2x - 8 + 7

⇒ y = - 2x - 1

Therefore, The equation of line passes through the point (-4, 7) will be;

⇒ y = - 2x - 1

Natalie works in a department store selling clothing. She makes a guaranteed salary of $300 per week, but is paid a commission on top of her base salary equal to 30% of her total sales for the week. How much would Natalie make in a week in which she made $225 in sales? How much would Natalie make in a week if she made x dollars in sales?

Answers

Answer:

The answer is below

Step-by-step explanation:

a) Natalie basic salary is $300 per week. She is paid a commission of 30% of her total sales for the week. Therefore her total weekly salary per week is given by:

Total weekly salary = Basic salary + Commissions

If Natalie makes $225 in sales, her commission = 30% of $225 = 0.3 × $225 = $67.5

Total weekly salary = Basic salary + Commissions = $300 + $67.5

Total weekly salary = $367.5

b) If Natalie makes $x in sales, her commission = 30% of $x = 0.3 × $x = $0.3x

Total weekly salary = Basic salary + Commissions = $300 + $0.3x

Total weekly salary = $(300 + 0.3x)

Answers

Question :

There are 3 different cheeses at the deli. Yasuko buys Three-fourths of a pound of each. There are also 4 different meats. She buys One-half of a pound of each. How much total meat and cheese did Yasuko buy at the deli? a) One-fourth pounds

b) 2 and one-fourth pounds

c) 4 and one-fourth pounds

d) 4 and one-half pounds

Answer:

c) 4 and one-fourth pounds

Step-by-step explanation:

From the question:

There are 3 different cheeses at the deli. Yasuko buys Three-fourths of a pound of each.

Total pounds of cheese = 3 × (3/4)

= 9/4 pounds of cheese

There are also 4 different meats. She buys One-half of a pound of each.

Total pounds of meats she bought = 4 × (1/2)

= 4/2 pounds of meat

The total pounds of total meat and cheese did Yasuko bought at the deli =

= 9/4 pounds of cheese + 4/2 pounds of meat

L.C.M = 4

= 9 × 1 + 4 × 2/4

= 9 + 8/4

= 17/4

= 4 1/4 pounds

In words is 4 and one-fourth pounds

On January 3, the high temperature in Anchorage, Alaska, was −24∘F. That same day, the high temperature in Minneapolis, Minnesota, was −9∘F. What was the difference between the temperature in Anchorage and the temperature in Minneapolis?

Answers

Answer:

-15

Step-by-step explanation:

-24-(-9)= -15

On January 3, the high temperature in Anchorage, Alaska, was −24∘F. That same day, the high temperature in Minneapolis, Minnesota, was −9∘F. Since, temperature is of interval scale, the difference between the temperature in Anchorage and the temperature in Minneapolis is of 15 degrees.

There are four scales of measurement. They are : nominal, ordinal, interval and ratio scale. Nominal and ordinal scales are for categorical data. Whereas, interval and ratio scale are for numerical data.

Interval scale only allows arithmetic operation addition and subtraction, but not multiplication and division.

Given in the question,

temperature of Anchorage, Alaska = −24∘F

temperature of Minneapolis, Minnesota =  −9∘F

difference in the two temperature =  −9∘F - ( −24∘F) = -9 + 24 = 15°F

A bus travels the 100 miles between A and B at 50 mi/h and then another 100 miles between B and C at 70 mi/h. The average speed of the bus for the entire 200-mile trip is:

Answers

Answer:

Average speed= 58.3 mi/hour

Step-by-step explanation:

The average speed is defined as the total distance traveled divided by the total time taken.

from A to B

distance= 100 miles

speed= 50 mi/h

speed= distance/time

time= distance/speed

time= 100/50

time= 2 hours

from B to C

distance= 100 miles

speed= 70 mi/h

speed= distance/time

time= distance/speed

time= 100/70

time= 10/7 hours

Average speed= total distance/total time

total distance= 200 mile

total time= 2+10/7= (14+10)/7= 24/7

Average speed= 200/24/7

Average speed= 200*7/24

Average speed= 1400/24

Average speed= 58.3 mi/hour
