Brady needs to cut a piece of scrapbook paper
12 centimeters long. He cuts pieces of the following
lengths. Which cut results in a percent error of 15%?
Select all that apply.
Answers
Answer:
Option A and Option C
Step-by-step explanation:
If we know that we have to cut a peice of paper 12 centemiters long, that means a 15% error would be cutting out one of the following lengths....
12 - 12(0.15) = 10.2 cm
or
12 + 12(0.15) = 13.8cm
So from this, we see that the answers are Option A and Option C
Jane spends about 1/6 of the day sleeping. How many hours in a day does Jane sleep? How many hours in a week?
Answers
Answer:
Jane spend 4 hours in a day sleeping, and 28 hours in a week.
Step-by-step explanation:
In 1 day, there are 24 hours. 24 multiplied by 1/6 is 4. I know this because 24 x 1/6 = 24/1 x 1/6 = 24/6 = 4/1 = 4.
In 1 week, there are 168 hours. 1/6 multiplied by 168 is 28. I know this because 168 x 1/6 = 168/1 x 1/6 = 168/6 = 28/1 = 28

The solution is Option G.
The value of the equation A = ( 2/3 ) x 15% x $ 2000 = $ 200
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
A = ( 2/3 ) x 15% x 2000 be equation (1)
On simplifying the equation , we get
A = ( 2/3 ) x ( 15/100 ) x 2000
A = ( 2/3 ) x ( 15 ) x ( 20 )
On further simplification , we get
A = ( 2/3 ) x 300
A = 2 x 100
A = $ 200
Therefore , the value of A is $ 200
Hence , the equation is A = $ 200

How many solutions does the following equation have ?
- 32 +9 – 2x = -12 – 5x
Choose 1 answer:
No solutions
B
Exactly one solution
С
Infinitely many solutions
Answers
Answer:Exactly one solution.
Step-by-step explanation:
- 32 +9 – 2x = -12 – 5x
1.Add numbers
-23 - 2x= -12-5x
2.Rearrange terms
-2x - 23 = -12 - 5x
3. Rearrange terms
-2x - 23 = -5x-12
4. Add 23 to both sides of the equation
-2x-23+23= -5x-12+23
5.Simplify
-2x= -5x+11
6.Add 5x to both sides of the equation
-2x+5x=-5x+11+5x
7.Simplify
3x=11
8.Divide both sides of the equation by the same factor
[tex]\frac{3x}{3}[/tex] = [tex]\frac{11}{3}[/tex]
9.Simplify and Solution
x= [tex]\frac{11}{3}[/tex]
