Scott has 25 counters. He gives 10 of the counters to Alex. a) What fraction of the 25 counters does Alex get? Give your answer in its simplest form. b) What fraction of the 25 counters does Scott have now? Give your answer in its simplest form.
Answer: a) Alex gets 10 counters out of 25, so the fraction of the counters he gets can be expressed as 10/25. To simplify this fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 5:
10/25 ÷ 5/5 = 2/5
So, Alex gets 2/5 of the 25 counters.
b) After giving 10 counters to Alex, Scott has 25 - 10 = 15 counters left. So, the fraction of the 25 counters that Scott has now can be expressed as 15/25:
15/25 ÷ 5/5 = 3/5
So, Scott now has 3/5 of the 25 counters.
Step-by-step explanation:
Answer:
Step-by-step explanation:
a) The counters that are in Alex= 10
The Fraction of 25 counters is = 10%25
Hence, the fraction of counters does Alex get is 2/5
b) Let the number of counters does Scott have = 25-10 =15
The fraction of 25 counters is = 15%25
Hence, the fraction of counters does Scott get is 3/5

3 is taken away from the product of 4 and 5
Answer: 4 x 5 - 3 = 17
Step-by-step explanation:
product is multiplication. 4 x 5 = 20
taken away is subtraction. 20 - 3 = 17
Therefore the answer of is 4 x 5 - 3 = 17
The following table shows the chemical makeup of one mole (a unit of measure commonly used in chemistry) of acetone and the approximate mass of a mole of each compound element.
Oxygen makes up what percent of the mass of one mole of acetone? Round to the nearest whole percent.
Answer:
55%
Step-by-step explanation:
You add all the grams and divide 16
16/29=0.551
then the nearest whole percent would be
55%
Each student in Ms. Karam’s science class uses one of the 20 lab stations for experiments. Ms. Karam lets students choose their own lab station. Gloria is the first in the class to choose a station for her work. José then chooses a lab station. Are the students’ choices dependent or independent? Explain in words how you determined your answer.
the students are independent because they choose, on their own, what stations they want to do their work at. I hope this helped

Identify the constant of proportionality.
Answer: 10
Step-by-step explanation:
The constant of proportionality k is given by k=y/x where y and x are two quantities that are directly proportional to each other.
So,
Let's take every point of the graph, than apply the equation.
When y is 10:
k = 10/1
When y is 20:
k = 20/2
When y is 30:
k = 30/3
When y is 40:
k = 40/4
When y is 50
k= 50/5
EVERY TIME, the answer is 10, take any point when this line graph is enlarged, the point on the line, are always going to be 10.
When y is (10) , then, x is 1 (as the point is in the x axis = 1
When y is (20), then, x is 2 (as the point is in the x axis = 2

Answer: 8(2x+7y)
Step-by-step explanation:
Factorisation here, in equation basically means, to put it into brackets.
Step 1 :
First we have to look for if anything is common, and there is! We can do the GCF of both numbers, the answer we will get will be out of the brackets.
GCF of 16 and 56 is 8
Step 2 =
No we do this =
8 x what is 16x? 2x
8 x what is 56y? 7y
so we got this = 8( 2x+7y)
So the final answer is 8(2x+7y)

The local botanical garden is setting up for a special event called "Music Mondays." They expect to have 100 people show up to the event and want to make sure that they have enough room for that many chairs. The first row has 8 chairs in it and each new row adds four chairs. How many chairs would be on the 5th row? Would 5 rows be enough to accommodate the 100 people?
Answer:
there will be 84 chairs which is not enough for 100 people.
Step-by-step explanation:
8+(8+4)=20, 20+(12+4)=36, 36+(16+4)=56 and 56+(20+4)=84 chairs.

Answer:
(5,-3)
Step-by-step explanation:
as you can see if you start from the origin and go sideways you end up at 5 in quadrant 4 then go down 3 and that is -3 since quadrant 4 is (+,-), (5,-3) also is separate from all the other points, all the other points are in quadrant 2.

Jonathan measured 2 cups of flour into a bowl on the counter. Than he spilled part of it, now there is 3/8 left. how much did he spill?
Answer:2 cups was our starting point and we were left with 3/8 cups left after he spilled it, we are looking to find how much he spilled.
We could start by making 2 into a fraction so we could minus 3/8 easily.
2 = 16/8 (Two wholes is 16 eights.)
Now solve like a regular subtraction equation.
16/8 - 3/8 = 13/8
Our answer is 13/8 which simplified as a mixed fraction is 1 5/8

Determine if each equation is linear or nonlinear.
Answer: Linear, Linear, Nonlinear, Linear
Step-by-step explanation:
Any equation for y where x is lacking an exponent is a LINEAR function.
Choice 3, when distributing 4x with x, produces 4x^2.
Thus, that is the only one not linear here (it is quadratic instead)
