What value of f makes the equation f + 4.02 = 6.5 true?

Enter your answer as a decimal number, like this: 42.53

Answers

Answer: f=2.48

Step-by-step explanation: hope you enjoy ;)

Given:-

[tex] \sf{f + 4.02 = 6.5 - - - eqⁿ}[/tex]

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.

Answers

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

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?

Answers

Answer:

there will be 84 chairs which is not enough for 100 people.

Identify the constant of proportionality.

Answers

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

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?

Answers

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
