Step-by-step explanation:

a y=3(‒4)+5 c y=3(2)+5

=‒12+5 =6+5

= ‒7 =11

b y=3(‒1)+5 d y= 3(5)+5

=‒3+5 =15+5

=2 =20

0.0008235 in scientific notation

Answers

Remember the rule, if the number is a decimal, it should be multiplied by 10^-n.
Formula = a * 10^-n
0.0008235 in scientific notation
=> 8.235 * 10^-n
There are 3 0s from the left side of the numbers and going to the decimal point.
So, we're gonna move 3 to the left
=> 8.235 * 10^-3.
Negative because it is a decimal number.

Answer: the actual answer would be 8.235 x 10^-4

Step-by-step explanation:

A cereal company used to fill the boxes with 16 ounces of cereal. They have reduced that amount to 14 ounces. The percent decrease is 87.5%. True or false

Answers

Answer:

False

Step-by-step explanation:

Given: A cereal company used to fill the boxes with 16 ounces of cereal. They have reduced that amount to 14 ounces.

Decreased amount = 16 -14 = 2 ounces.

Now let's find the decreased percentage using the following formula.

Decrease percent = $(decreased amount)/(original amount) *100$

= $(2)/(16) *100$

= $(200)/(16)$

= 12.5%

The percentage of decrease is 12.5%.

Therefore, the answer is false

This is a true statement

%87.5 = .875 in decimal form
multiply 16 by 8.75 and it will give you 14

You are going to paint stripes on one wall of your bedroom. the wall is 13.3 feet wide, and you want to paint 14 stripes. about how wide should each stripe be?

Answers

The 14 stripes would be equal to 13.3 feet wide wall.

14 stripes = 13.3 feet

1 stripe = 13.3/14 = 0.95

So each stripe would be 0.95 feet wide.

Hope this helps.

The width of each stripe is 0.95 ft.

What is width?

Width tells us that how wide a thing is, width is the wideness of a thing.

Given that, You are going to paint stripes on one wall of your bedroom. the wall is 13.3 feet wide, and you want to paint 14 stripes.

We know that the width of the wall = 13.3 feet

We also know that the number of stripes to be painted = 14

Width of one stripe = (the width of wall)/(total number of stripe)

Width of one stripe = 13.3/14

Width of one stripe = 0.95 feet

Hence, the width of one stripe would be 0.95 feet
