Amber has 4/5-pound bag of colored sand. She uses 1/2 of the bag for the project. How much sand does she use for the project?

Answers

Answer 1
Answer:

Answer:

(2)/(5)-pound of sand

Step-by-step explanation:

We have been given that Amber has (4)/(5)-pound bag of colored sand. She uses 1/2 of the bag for the project.

We need to find 1/2 'of' the 4/5 as:

(4)/(5)* (1)/(2)

(4*1)/(5*2)

(2*1)/(5*1)

(2)/(5)

Therefore, Amber used (2)/(5)-pound of sand for the project.
Answer 2
Answer: 3/10
4/5 - 1/2= 8/10-5/10

A. 3 and 4

We know the square root of 9 is 3, and the square root of 16 is 4, so the square root of 12, which is between 9 and 16, must be between 3 and 4.

The standard diameter of a golf ball is 42.67 mm. A golf ball factory does quality control on the balls it manufactures. Golf balls are randomly measured to ensure the correct size. One day, an inspector decides to stop production if the discrepancy in diameter is more than 0.002 mm. Which function could represent this situation?A. f(x ) = x – |42.67|
B. f(x ) = |x| – 42.67
C. f(x ) = |42.67 – x|
D. f(x ) = 42.67 – |x|

Answers

The correct answer is:
C) f(x)=|42.67-x|.

Explanation:
Production will be stopped if the difference in diameter is greater than 0.002 mm.
This difference can mean that the golf ball has a diameter more than 0.002 larger than 42.67 mm, or a diameter more than 0.002 smaller than 42.67. This is the reason for using an absolute value function.
 Absolute value represents the distance a number is from 0. For this function, we would want only the values where the function is less than 0.002.

Question: Michelle is making goodie bags for Christmas filled with chocolate and candy. Chocolates cost $2.50 per lb and candy cost $3.00 per lb. Michelle spent a total of $40 on 20 lbs of candy. How much of each kind of candy did she purchase ?

Answers

Michelle purchased 5 lbs of chocolates and 5  lbs of candy.

Let assume Michelle purchased x lbs of chocolates and y lbs of candy.

According to the given information,

Michelle spent a total of $40 on 20 lbs of candy.

So, the equation can be set up as:

Equation 1: 2.50x + 3.00y = 40

As, the totalweight of candy is 20 lbs, so we have:

Equation 2: x + y = 15

From equation 2: x = 15 - y

Substitute the value of x= 15 - y into Equation 2 as

2.5(15-y) + 3y = 40

37.5 - 2.5y + 3y= 40

0.5y =  2.5

y= 5

Substituting y= 5 into the second equation

x + 5  = 10

x = 10 -5

x = 5

Thus, 5 lbs of chocolates and 5  lbs of candy were bought.
