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

Number of Girls= Total number of people attended the study - ( Number of adults + Number of boys)

392- ( 105+89)

392- 194

=198 Girls

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

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:

The question is unclear. Please provide the table.

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:

-If the legs of the triangle added up are bigger than the hypotenuse, its an acute tri.

-if they are smaller then its and obtuse angel

-if the legs added up are = to the hypotenuse, then the triangle Is a right triangle.

your right triangle is:

5,12,13

Step-by-step explanation:

Because 5^2+12^2=13^2

It is true

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:

y = -(1/7)x + 1

Step-by-step explanation:

[tex]3x + 21y = 21 \\ 21y = 21 - 3x \\ y = \frac{21 - 3x}{21} \\ y = 1 - \frac{1}{7} x \\ y = - \frac{1}{7} x + 1[/tex]

Answer:

- 15

Step-by-step explanation:

[tex] \frac{1}{3} a = - 5 \\ \\ a = - 5 \times 3 \\ \\ a = - 15[/tex]

Answer:

-15

Step-by-step explanation:

As you can see, the denominator of 1/3 is 3. 1 third of a is -5. So what you do is, you multiply -5 * 3 and that'll give you -15. So, it is equal to -15.

Answer:

Third option is the correct answer

Step-by-step explanation:

Point T is between the point R and point S.

Answer:

the nearest is 50%

Step-by-step explanation:

45/90 = 0.50 = 50%

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.

The number (x) in: "5 more than three times a number is 17" is what we are solving here.

In other words, you are looking for a number (x) that if you multiply it by three (same as three times) and then add 5, you get 17.

To solve this, you first write the problem as an algebra equation as follows: 3x + 5 = 17

Then you solve the equation by subtracting 5 from both sides, and then divide both sides by 3. Here is the math to illustrate better:

3x + 5 = 17

3x + 5 - 5 = 17 - 5

3x = 12

3x/3 = 12/3

x = 4

Answer = 4
