A lawnmower that regularly sells for $150 is on sale for $120. By what percentage was the price decreased?
Answer:
20%
Step-by-step explanation:
Find the difference of both prices.
150 - 120 = 30
Calculate the ratio of the decrease in price to the original price.
30/150 = 0.2
Multiply the decimal by 100 to get your percentage.
0.2(100) = 20

What is Coordinates?A pair of numbers which describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinates.
Given that;
On a coordinate plane,
Point B is at (- 8, 10),
Point C is at (8, 10),
Point D is at (2, - 2),
Point E is at (- 8, - 4).
Now, We know that;
The distance between two points (x₁ , y₁) and (x₂, y₂) is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
Thus, The length of side BC is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (8 - (-8))² + (10 - 10)²
⇒ D = √ 16²
⇒ D = 16
Thus, The length of side CD is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (2 - 8)² + (-2 - 10)²
⇒ D = √ -6² + (-12)²
⇒ D = √ 36 + 144
⇒ D = √ 180
⇒ D = 13.4
Thus, The length of side ED is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (2 - (-8))² + (-2 - (-4))²
⇒ D = √ 10² + 2²
⇒ D = √104
⇒ D = 10.2
Thus, The length of side BE is,
⇒ D = √ (x₂ - x₁)² + (y₂ - y₁)²
⇒ D = √ (- 8 - (-8))² + (10 - (-4))²
⇒ D = √ 14²
⇒ D = 14

Kevin is driving a truck filled with mulch. The mulch is packed in a container 20 feet long, 15 feet wide, and 12 feet tall. If each cubic foot of mulch weighs 5.6 pounds, what is the weight of the mulch in the truck?
Answer:
20160 pounds
Step-by-step explanation:
20 * 15 * 12 = 3600 feet^3 = Volume
3600 feet^3 * 5.6 pounds = 20160 lbs
Answer:
The answer is 3605
Step-by-step explanation:
That is the answer because you have to do 20x15x12 and that will equal 3600 and then you do 3600+5.6 and that will equal 3605

Step-by-step explanation:
The probability of selecting exactly 2 right-handed people are approximately 20% of the time.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
We know that, probability of an event = Number of favourable outcomes/Total number of outcomes.

Answer:
3 1/8
Step-by-step explanation:
Subtract and then simplify
Answer:
Step-by-step explanation:
1. You know that:
- The zookeeper is 6 1/4 feet tall.
- The young giraffe is 9 3/8 feet tall.
2. Then, to calculate how many times as tall as the zookeeper is the girraffe, you only need to divide the height of the giraffe by the height of the zookeeper:
- Let's rewrite each height as a decimal number: divide the numerator and the denominator of the fraction and add the result to the whole number:
- Divide 9.375 feet by 6.25 feet, then you obtain the following result:
