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

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

392- ( 105+89)

392- 194

=198 Girls

Answer:

x = 29°

y = 29°

z = 102°

Step-by-step explanation:

x and y both look even to the 29° angle across from them and z looks even to the 102° angle across from it.

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:

(8, -5); x=8; y=-5

Step-by-step explanation:

i'll be solving via substitution

2x+3y=1; y=-2x+11

2x + 3(-2x +11) = 1

2x -6x +33 = 1

-4x = -32

x = 8

2(8) + 3y = 1

16 + 3y = 1

3y = -15

y = -5

(8, -5)

Check:

-5 = -2(8) + 11

-5 = -16 + 11

-5 = -5

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:

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:

write your answer as a decimal, then round

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

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.

If the missile was going 900 mph and we are trying to find the horizontal velocity

This could be 3.88, and rounding it to the nearest hundredth would be 3.90 miles per minute

Answer:

1.45 miles per minute

Step-by-step explanation:

The question asked it to be presented in miles per minute so divide 1000 by 60 which will give us 50/3. We then multiply that with cos(85) which will give us the final answer of 1.45.
