Crayons are on sale for $.25 for a pack of 16. This was down from the normal price of $.75 per 16 pack. What is the percent discount buyers are getting per crayon at this sale price?
Answers
Answer:
2/3 or 66.7%
Step-by-step explanation:
The old price of 1 crayon was 75/16 or about 4.69 cents
The new price of 1 crayon is 25/16 or about 1.56 cents
now to find the discount you can find out how much percent of 4.69 is 1.56 and then subtract from 1 if you use a fraction or 100 if you use percentage to get the final answer.
(1.56/4.69) * 100= 1/3
1 - 1/3= 2/3

87/200
43.5/100
870/200
435/1000
Answers
Answer:
B
Step-by-step explanation:
For the question we can eliminate c because c doesn't= up to 43.5.
for A and 87/200 simplified would=43.5 same thing with 435/1000=43.5%
We eliminate D though because when D is simplified it turns into 87/200 and then 87/200 simplifies to 43.5%
So the lowest fraction and lowest form is 43.5/100

In terms of pi, the area is 25/π square inches.
Step-by-step explanation:
Circumference = 2πr
10 = 2πr

The school band is selling candy to raise $1,800.00 to pay for their trip to a band festival. The band earns $1.50 from every box of candy sold. Kayla solved the inequality 150 x greater-than-or-equal-to 1,800 to find the number of boxes the band must sell to meet their goal. She graphed her solution on a number line and interpreted the solution to mean the band will meet their goal if they sell fewer than 12 boxes.
A number line going from 6 to 16. A closed circle is at 12. Everything to the right of the circle is shaded.
What errors did she make? Select two options.
She used the wrong coefficient for x in her inequality.
She should have used the less than or equal to symbol instead of the greater than or equal to symbol.
She interpreted the graph incorrectly.
She graphed a solution set that does not match her inequality.

Step-by-step explanation:
All three interior angles of the the triangle equals 180 degrees.
100+44= 144
180-144= 36
The missing interior angle equals 36.
The exterior angle and the missing angle form a straight line. The angle of straight lines are always 180 degrees.
180-36= 144 degrees
The measure of the exterior angle is 144 degrees.
