It costs $7.00 to purchase a
pair of goggles. then marks
the goggles up by 75%. How
much does Sam charge for a pair
of goggles ?
Answer:
12.25 U.S. dollars
Step-by-step explanation:
Answer:
$12.25
Step-by-step explanation:
We can solve this by first finding 75% of $7. To do this, we can do $7.00 x 0.75. The product of those is 5.25. Knowing that $5.25 is 75% of $7, we are able to add up $7 and $5.25, which gives us $12.25.

An electric powered fan has a 9 inch diameter blade that
rotates at 4000 revolutions per minute.
Find the angular speed of the sword in radians per minute.
_____/-\radians/minute
The speed of the fan is 1884 inches per second.
Step-by-step explanation:
Revolution per minute= 4000
Radius = 4.5 inches
Circumference= 2π r
= 2(3.14) (4.5)
= 28.26 inches
1 revolution= 28.26 inches
4000 revolution= (28.26) (4000)
=113040 inches per minute
= 113040/60
= 1884 inches per second
The speed of the fan is 1884 inches per second.
Final answer:
To find the angular speed of a fan blade given its revolution per minute, multiply the revolutions per minute by 2π to get the angular speed in radians per minute.
Explanation:
An electric powered fan has a 9-inch diameter blade rotating at 4000 revolutions per minute. To find the angular speed in radians per minute, we can use the formula: Angular speed (in rad/min) = (revolutions per minute) x 2π. Therefore, angular speed = 4000 x 2 x π = 8000π rad/min. So, the angular speed of the fan blade is 8000π radians per minute.

Step-by-step explanation:
You open up the (3x+5)^2 and get:
9x^2 + 30x + 25
So...
a+b+c = 64

Write an algebraic expression for the number of hours in m minutes
Answer:
m/60.
Step-by-step explanation:
There are 60 minutes in an hour so the expression is m/60 hours..
The algebraic expression for the number of hours in m minutes is m/60. This is because there are 60 minutes in an hour, so dividing the number of minutes by 60 gives the equivalent number of hours.
Explanation:The task is to write an algebraic expression that represents the number of hours in m minutes. Since 1 hour is equal to 60 minutes, we can set up a conversion factor that allows us to go from minutes to hours. To find the number of hours in m minutes, we divide the number of minutes by 60 (the number of minutes in an hour). So, the algebraic expression for the number of hours in m minutes would be m/60.
To further simplify the context, think of a situation where you might need to convert 120 minutes to hours. Using the algebraic expression described, you would divide 120 by 60, which would result in 2. Therefore, 120 minutes is equal to 2 hours.

What is the value of the expression when x = -2?
When x is substituted with -2 in the given expression, the value of the expression is 1.
Explanation:Given the expression and the value of x, we can substitute x with -2 and evaluate the expression. For example, if the expression is x² + 2x - 3 and you want to find the value when x = -2, then you'd substitute x = -2 into the expression giving (-2)² + 2*(-2) - 3 = 4 - 4 - 3 = -3. Substituting values in, simplifying, and solving is the general process to follow when coming across this kind of problem in quadratic equations or other areas of Algebra.
Let's say the expression is 2x + 5. Substituting x with -2, we get:
2*(-2) + 5 = -4 + 5 = 1
Therefore, the value of the expression when x = -2 is 1.

The pythagorean theorem
Answer:
In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.

Answer:
A. 25 miles per gallon
B. 225 miles
Step-by-step explanation:
Part A is asking for an average - how many miles does the car get out of each gallon. This can be found by dividing the total change in miles by the total change in gallons.
In this case, the changes in each are:
250 miles
10 gallons
250/10 is 25. Thus there are 25 miles per gallon.
Part B is asking for how much can you get with 9 gallons, meaning how many miles corresponds to 9 on the graph. The graph is at 225 miles at the x=9 mark, and thus the answer for part be is 225.
