A. His grades
B. The hours he studies

Answer:

418

Step-by-step explanation:

first row = 13 chairs

next 15 rows are 15 chairs each so

15 x 15= 225

the remaining rows are 10 and they have 3 extra chairs so 18 chairs and 10 remaining rows

10x 18=180

now add 13+225+180=418

hope this helps

Answer:

130°

Step-by-step explanation:

∠JDG and ∠EDF are opposite angles. The measures of arcs for opposite angles always add up to 180°. Since the arc for ∠JDG is 50°, the arc for ∠EDF has to be 130°, because 50 + 130 = 180.

Answer: 23.7

Step-by-step explanation:

Let's calculate the acute angle at the base of the triangle:

180° - 90° - 40° = 50°

Find side x:

[tex]\dfrac{sin \: 90^{o} }{31} =\dfrac{sin \: 50^{o} }{x}\\\\sin \: 90^{o} \cdot x=sin \: 50^{o} \cdot 31\\\\sin \: 90^{o} =1\\sin \: 50^{o} \approx 0.766\\1 \cdot x =0.766 \cdot 31\\x=23.746\\23.746 \approx 23.7[/tex]

Answer:198 Girls were there

Step-by-step explanation:

Total number of people tthat attended the study = 392

Number of adults = 105

Number of boys = 89

392- ( 105+89)

392- 194

=198 Girls

Answer:

20% of 50 marbles is 1 fifth of the marbles in the bag. so 50 marbles divided by 5 =10 blue marbles

Step-by-step explanation:

Answer:

40

Step-by-step explanation:

WOW, that's a lot of points!!

To find the answer for this problem, you take 80% of 50.

In the bag, 20% of the marbles are blue. That means that the rest of the 80% are not blue. So, take 0.8 * 50 = 40. 40 marbles that are not blue.

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that Brock divided all of his games into 3 shelves, and there were at least 12 games on each shelf.

The inequality that matches this scenario will be:

x ≥ 12.

Since there were at least 12 games, we would use the greater than or equal to sign.

Answer:

34/100

Step-by-step explanation:

Answer:

17/50

Step-by-step explanation:

Hi!

How you want to go about this is first make the 3/10 into 30/100 to make it match up with 4/100.

You want the denominators to both be 100 so they match.

So you would do this by finding 10 x what gets you to 100.

You could eyeball it and see that 10 x 10 = 100 or go backwards (right to left horizontally) and divide 100 / 10 to get 10.

But now what we have is :

30/100 + 4/100

All you have to do is add the first numbers and simplify if possible.

30 + 4 = 34

So :

34/100

To simplify we can divide both numbers by 2 :

34/2

100/2

17/50

And that is our final answer.

I hope this helped!

Answer:

41/99

Step-by-step explanation:

Simplest form of the number 0.41 repeating; 41/99

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction.

It can be written as the form of p : q, which is equivalent to p / q.

We are Given that 0.41 repeating.

Consider x = 0.41, then multiply both sides of this equation by 100 to remove the decimal point:

100x = 41.41

Simplifying;

99x = 41

Dividing both sides by 99;

x = 41/99
