Answer:

53 1/3% for the first answer, and 33 1/3% increase for the second answer

Step-by-step explanation:

Ok, lets start up witht eh first question.

We need to find the percentage of studens that find math the be their favorite subject in elementary school.

We know that there are 15 kids in total.

We specificly see that 8 of those kids like math the most.

To find percentage, divide 8 by 15.

Using a calculator you should find 53 1/3% of the students found math to be their favorite subject.

Next we need to find the percentag eof change that history is over elementary school to high school.

This might sound confusing, but this is basically just a change of 3 students to 4 students.

To find percentage, just divide 3 by 4:

This gets you 33 1/3%

Hope this helps!

Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner.explain

GarryVolchara [31]

Okay, so:

You would want to find what 1/10 of the laptop costs. That would be the 10% of money left in Kai's account.

So,

423*.1

(you have to turn the percentage into a decimal; 10%= .10

423*.1= 42.3

So, Kai has 42.3 dollars left to buy a scanner. He only has 10% of his bank account left to spend on the scanner.

I hope this helps!

Point B(6, -3) is translated using the rule (x -5 y + 9) what is the y coordinate of B'

Andrej [43]

This rule shows how we transition the x-coordinate and y-coordinate when finding B'.

In this rule, it shows us what to add/subtract from the x-value and y-value in the coordinate. We can see that it wants us to subtract 5 from the x-value (based on the "x - 5") and that it wants us to add 9 to the y-value (based on the "y + 9"). Based on this information, we can find B':

$\textrm{B}'(6 - 5, -3 + 9)$

$\boxed{\textrm{B}\,'(1, 6)}$

The "y-coordinate" of B' is 6.
