There were 49 questions in the exam and Peter answered 45 questions correctly. Find the percent of error.A.

A

Step-by-step explanation:

49-45 = 4 wrong

4/49 = 0.08163

        = 8.16%

A) 8.16

Step-by-step explanation:

1) Subtract 49-45

2) Divide 4/49 and multiply by 100

3) Then multiply by 100

Hope this helped

11. it is the only odd number

4 bc it doesn’t add up

5/6 * 3/3 = 15/18if u take ur fraction and multiply it by the same numerator and denominator, the result will be an equivalent fraction.

example :
if I multiplied 5/6 * 2/2 = 10/12...this is also equivalent...
5/6 * 4/4 = 20/24and this is equivalent as well.

so ur answer is 15/18

1.312

explanation: 8.2×0.16= 1.312

 2 (third option)

Step-by-step explanation:

The equation of inverse  variation where the variable "x" varies inversely as the variable "y", has the form:

[tex]x=\frac{k}{y}[/tex]

Where "k" is the constant of variation.

As you know that [tex]x=4[/tex] when [tex]y=8[/tex], then you can substitute values and solve for the constant of variation "k":

[tex]4=\frac{k}{8}\\\\k=4*8\\k=32[/tex]

Substitute "k" and [tex]y=16[/tex] into  [tex]x=\frac{k}{y}[/tex] to find x when [tex]y=16[/tex]:

[tex]x=\frac{32}{16}\\\\x=2[/tex]

-1.7

Step-by-step explanation:

To solve this, you use the rule of BODMAS

Bracket of Division, Multiplication, Addition and Subtraction. This states that when faced with a mathematical problem involving more than one sign, you solve the problem in that order of signs.

16÷7-8÷2

In the question above, we have the Division sign and minus sign. From the BODMAS rule, we solve the division first before the minus.

16÷7 - 8÷2

2.28-4

=-1.7

1. 20/32

C. 10/16, 5/8

2. 6/8

C. 3/4

3. 3/12

A. 1/4

I hope I helped
