A clockwise rotation of 90 degrees is equivalent to a counter clockwise rotation of how many degrees?
The counter-clockwise rotation of the clockwise 90-degree rotation will be 180 degrees.
What is clockwise rotation?Clockwise motion, also known as CW, moves from top to bottom, then down and left, and then back to top in the same manner as a clock's hands. The opposing direction of rotation or revolution is anticlockwise (ACW) or counterclockwise (CCW).
Given that there is a rotation of 90 degrees clockwise. The counterclockwise rotation will be calculated as.
The counterclockwise rotation will be equal to 180 degrees because the rotation will be first of 90 degrees and again of 90 degrees, Mathematically written as,
Counterclockwise rotation = 90 + 90
Counterclockwise rotation = 180
Therefore, the counter-clockwise rotation of the clockwise 90-degree rotation will be 180 degrees.

You purchase a car using a $20,000 loan with a 5% simple interest rate.
(a) Suppose you pay the loan off after 4 years. How much interest do you pay on your loan? Show your
work and don’t forget the unit!
(b) Suppose you pay the loan off after 3 years. How much interest do you save by paying the loan off
sooner? Show your work and don’t forget the unit.
Answer: a) b)
The total interest paid on a $20,000 loan at 5% simple interest over 4 years is $4,000.
To solve part (a) of the question, we calculate the amount of interest paid on a $20,000 loan over 4 years with a 5% simple interest rate:
Calculate the annual interest: $20,000 * 5% = $1,000.
Multiply the annual interest by the number of years: $1,000 * 4 years = $4,000.
The total interest paid after 4 years is $4,000.
For part (b), to find the interest saved by paying off the loan after 3 years instead of 4 years, we do the following:
Calculate the interest for 3 years: $1,000 imes 3 years = $3,000.
Deduct the 3-year interest from the 4-year interest: $4,000 - $3,000 = $1,000.
The interest saved by paying the loan off after 3 years is $1,000.
A machine makes 20 carpets in a day. After oiling the machine, its efficiency will go up by 150%. How many carpets will be produced at this level?
After a 150% efficiency increase, a machine that initially produces 20 carpets will produce 50 carpets per day.
If a machine is currently making 20 carpets a day and its efficiency increases by 150%, the new production can be calculated as follows:
First, we understand that an increase of 150% in efficiency is the same as multiplying the current efficiency by 1 + 1.50 (where 1 represents the current efficiency and 1.50 represents the increase). This gives us a factor of 2.50 (or 250%).
Now we apply this factor to the current production:
Multiply the current production (20 carpets) by the efficiency factor (2.50).20 carpets 2.50 = 50 carpetsAfter oiling the machine, it will therefore produce 50 carpets per day.
Round off 0.482 to one significant figure
To round 0.482 to one significant figure, consider the first non-zero digit '4' and round up to '5' because the next digit is '8', giving you 0.5.
To round off the number 0.482 to one significant figure, you look at the first non-zero digit, which is '4' in this case. Since the digit to the right of '4' is '8', which is greater than 5, you round up the '4' to '5'. Therefore, 0.482 rounded to one significant figure is 0.5.
Using examples from provided references:

To find an equivalent fraction to 2/5 with a denominator of 15, multiply both the numerator (2) and the denominator (5) by 3, resulting in the fraction 6/15.
Explanation:To find a fraction equivalent to 2/5 that has a denominator of 15, we need to scale up the original fraction so that the denominator becomes 15. This is done by finding a number that you can multiply the denominator by to get 15. Since 5 × 3 = 15, we multiply both the numerator and denominator of 2/5 by 3 to maintain the same value.
Here's the calculation:
Multiply the numerator by 3: 2 × 3 = 6Multiply the denominator by 3: 5 × 3 = 15
Therefore, the fraction that is equivalent to 2/5 with a denominator of 15 is 6/15.

Carlos has 4 1/2 gallons of paint. To paint a room that is 10 ft by 10 ft, he uses 34 gallon of paint. How many 10 ft by 10 ft rooms can Carlos paint? A. 4 1/3 rooms B. 4 2/3 rooms C. 6 rooms D. 9 rooms
Carlos can paint 6 rooms with the available 4 1/2 gallons of paint.
To paint one 10 ft by 10 ft room, Carlos uses 3/4 gallons of paint. To find how many rooms Carlos can paint with the available 4 1/2 gallons of paint, we divide the total paint available by the paint used per room.
Number of rooms = Total paint available / Paint used per room
Number of rooms = 4 1/2 / 3/4
Number of rooms = 9/2 / 3/4
To divide fractions, multiply by the reciprocal of the divisor
Number of rooms = 9/2 * 4/3
Number of rooms = 36/6
Number of rooms = 6
Carlos can paint 6 rooms with the available 4 1/2 gallons of paint. Therefore, the correct answer is C. 6 rooms.

The ratio of the amount of almonds in Bag A to the amount of bag B was 8:5. After 12 ounces of almonds were transferred from Bag A to Bag B, the amount of almonds in Both bags became the same. How many ounces of almonds were originally in Bag B?
To solve this problem, we can set up an equation using the given information and solve for x. The original amount of almonds in Bag B was 40 ounces.
Explanation:To solve this problem, we can set up an equation using the given information. Let's assume that the original amount of almonds in Bag A is 8x ounces and the original amount of almonds in Bag B is 5x ounces.
After 12 ounces of almonds are transferred from Bag A to Bag B, the amount of almonds in both bags becomes the same. This means that the amount of almonds in Bag A is now 8x - 12 ounces and the amount of almonds in Bag B is now 5x + 12 ounces.
Setting up an equation based on the ratios, we have:
8x - 12 = 5x + 12
Solving for x, we find that x = 8.
Therefore, the original amount of almonds in Bag B was 5x = 5(8) = 40 ounces.

the number of Tim's stamps is 3/4 the number of david's stamps. if tim gives 1/2 of his stamps to david, what will be the ratio of the number of tim's stamps to the number of david's stamps
To find the new ratio of Tim's stamps to David's stamps after he gives half of them to David, we set up a proportion using their initial amounts and the given fractions. The new ratio, after simplification, is 1 : 3 2/3 (or 1 : 3.67 in decimal form).
Explanation:To solve the problem, we need to set up a ratio and proportion based on the information given. Initially, the number of Tim's stamps is 3/4 the number of David's stamps. If Tim gives 1/2 of his stamps to David, the situation changes, and we need to calculate the new ratio of their stamps.
Let's assume David has D stamps. So, Tim has 3/4 * D = 3D/4 stamps initially. When Tim gives away half of his stamps, he gives 1/2 * 3D/4 = 3D/8 stamps to David.
Now, David has D + 3D/8 stamps, and Tim has 3D/4 - 3D/8 stamps. Simplifying these expressions gives us:
David's new total: D + 3D/8 = 8D/8 + 3D/8 = 11D/8Tim's new total: 3D/4 - 3D/8 = 6D/8 - 3D/8 = 3D/8The new ratio of Tim's stamps to David's stamps is 3D/8 : 11D/8. We can simplify this by dividing both parts by 3D/8, which gives us:
3D/8 : 11D/8 = 1 : 11/3 = 1 : 3 2/3 or 1 : 3.67 in decimal form.

the pizzeria buys 250 pounds of mozzarella cheese if they use 20 5/6 pounds of cheese every day how long will the cheese last
To determine how long the pizzeria's cheese supply will last, we divide 250 pounds by the daily usage of 20 5/6 pounds, which equals approximately 12 days.
Explanation:To calculate how long the pizzeria's 250 pounds of mozzarella cheese will last, given that they use 20 5/6 pounds of cheese every day, we have to divide the total amount of cheese by the daily usage. The fraction 5/6 needs to be converted to a decimal for ease of calculation. So 5/6 is approximately 0.833. Therefore, the daily usage is 20 + 0.833, which is 20.833 pounds.
Next, we divide the total amount of cheese by the daily usage to find how many days the cheese will last:
250 ÷ 20.833 ≈ 12 days
Therefore, the mozzarella cheese will last for approximately 12 days.
