She had $3000. She spend 40% of the money in smart TV and 15% of the remainder on Game Set. (a) What % of the money had she left? (b) How much money had she left?
Answer: She had left 54% of the money which is $1620.
Step-by-step explanation:
40% of $3000 = $1200
15% of $1200 = $180
$3000 - ($1200 + $180)
$3000 - $1380 = $1620
$1620 is the money she had left.
$1620 is 54% of $3000
She had 54% left of the money.

if 2 of the angles of a triangle are 30 and 70 degrees, the third angle measures ...
Answer:
The third angle would measure 80 degrees
Step-by-step explanation
The equal measure of each angle in a triangle adds up to 180 degrees. The first two angles of 70 and 30 equal 100. Thus, the third angle will measure out to be 80 degrees. Have a great day!

Explain how to solve 5d = 35
Answer:
D=7
Step-by-step explanation:
SO isolate the variable y dividing 5 on both sides
d=7
Answer: d = 7
Step-by-step explanation:
5d = 35
You have to divide both sides by 5 since we need to isolate the variable 'd' to figure out what d is.
5d ÷ 5 = d
35 ÷ 5 = 7
So d = 7

Garrett arrived at the train station at 12:35 P.M. His train finally came at 1:30 P.M. How long
did Garrett have to wait for the train?
Answer:
55 minutes
Step-by-step explanation
He started waiting at 12:35 P.M. If we're assuming this is the same day, you're able to add the minutes until you get to 1:00 P.M., which is around 25 minutes. Afterwards, you need to add another 30 minutes to get to the train's time of arrival, which means you should get 55 minutes!
Calvin is comparing the growth of two plants. Plant A started at a height of four inches and grows two inches each month. Plant B grew according to this equation, h = 4m + 2, where h, is the height after m, months. At what month will the two plants be the same height?
Answer:
After 1 month, they will have same heights.
Step-by-step explanation:
Calvin is comparing the growth of two plants.
Plant A started at a height of four inches and grows two inches each month.
h'=4+2m
where
h' is height of plant after m months.
Plant B grew according to this equation, h = 4m + 2, where h, is the height after m, months.
We need to find at what month the plants have the same height. ATQ.
h = h'
4+2m = 4m + 2
Taking like terms together,
4-2 = 4m-2m
2=2m
m = 1
Hence, after 1 month, the plants will have same height.

Answer: the answer to this is 9 miles an hour
Step-by-step explanation: 1. What this is asking is to make the fraction a bit easier to understand. So all we do is divide the numerator by the denominator. You can use this method for any other math problems like this also.
2. All this chart is doing is multiply the input or output by 9. If you look you can see the hours is multiplied by nine. I hope this helped.

3/ If f(x) = 2x -5 Find f(x-1)=
Explanation: Here we have function f(x) = 2x - 5
and we're asked to find f(x - 1).
Don't be thrown off if you're asked to plus a variable into a function.
If f(x) = 2x - 5, then f(x - 1) = 2(x - 1) - 5.
Remember to use parenthses when substituting into a function.
So simplifying on the right side, we would distribute the 2
through the parenthses and we have 2x -2 - 5.
Now combining like terms, we have 2x - 7

Answer:
What do you mean?
Step-by-step explanation:
is 9.521521521 rational or irrational
If the numbers after the decimal terminate, yes, it's rational.
9.521521521 = 9,521,521,521 / 1,000,000,000
If they don't terminate, but the pattern continues (which I suspect is the case here), yes, it's still rational.
If x = 9.521521521…, then
1000x = 9521.521521521…
Subtract x from this to eliminate the fractional part:
1000x - x = 9521.521521521… - 9.521521521…
999x = 9512
x = 9512/999
If they don't terminate, but the pattern does not continue, meaning the next few digits could be something random like
9.52152152119484929271283583457…
then the number would be irrational.

Write a linear function f with the given values. f(6)=-2, f(0)=-5
Answer:
y = 0.5m - 5
Step-by-step explanation:
the equation of a line can be written as
y = mx + b, with x being the input and y the output
let's plug in our two values.
-2 = m(6) + b
-2 = 6m + b
-5 = 0m + b
-2 = 6m+b
-5 = b
plug -5=b into the first equation
-2 = 6m - 5
add 5 to both sides
3 = 6m
divide both sides by 6
0.5 = m
our function is now
y = 0.5m - 5

Lin says that a snack machine is like a function because it outputs an item for each code input. Explain why Lin is correct.
Lin is correct.
What is a function?An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable, is called its function.
Given that, Lin says that a snack machine is like a function because it outputs an item for each code input.
Lin is correct because, function tells the relation between an output to its input.
A function is a relation from the set of the inputs to a set of all possible outputs, where each input is related to exactly one output.
So Lin's opinion about snack machine is correct as the snack machine is output an item for each code input.
