Answer:

25-10=15

Step-by-step explanation:

Answer:

a straight line which is 180°

Answer:

A = 54 is the correct answer!

Step-by-step explanation:

I did this test too! Hope this helped!

Answer:

49°

Step-by-step explanation:

49^2 - 32^2 = BC^2

2401 - 1024 = 1377

√1377 = 37.1079506

37.1 m

Sin(A) / 37.1 = Sin(90)/ 49

Sin (A) = 37.1 X Sin(90)/49

A = sin^-1(3.71 X sin90)/49

A = 49.21

Answer:

Step-by-step explanation:

[tex]y - 15 = 20 \\ y - 15 + 15 = 20 + 15 \\ y = 20 + 15 \\ y = 35[/tex]

I hope that is useful for you :)

Easy. Just take -15 to the right hand side of the equation, which will give you, y = 20+15, implies y = 35.

Answer:

23w

Step-by-step explanation:

For 6days, She skates 3 * 6 = 18 miles

on weekend she skates 5 miles

Thus, In one week, she skates 23miles

In w week, she skates: 23w

in this exercise we have to know conversion, so it will be necessary to correct the space in time, which will represent in weeks:

28 weeks

So first, we have to calculate the total distance traveled in every day, like this:

[tex]days: 6*3=18\\weekends: 5*2=10\\total:18+10=28[/tex]

Step-by-step explanation:

Answer:

$115

Step-by-step explanation:

Amount Harry had in the account = $450

He had $565 after the deposits.

We need to find the amount deposited by Harry.

Deposited amount = final amount-initial amount

= $565 - $450

= $115

So, each deposit is $115.

Answer:$57.50

Step-by-step explanation:

2x + 450 = 565

2x + 450 - 450 = 565 - 450

2x = 115

2x/2 = 115/2

x = 57.50

Kindly note that the spinner diagram. Wasn't given and the spinner used was just hypothetical.

Answer:

1 /18

Step-by-step explanation:

Sample space for spinner = (a, b, c, d, e, F, G, h, I) = 9

Total possible outcomes = sampme space

Vowels in spinner = (a, e, I)

Number of vowels = required outcome = 3

P(spinning a vowel) = required outcome / Total possible outcomes

P(spinning a vowel) = 3 / 9 = 1/3

For a six sided dice ;

Required outcome = (6) = 1

Total possible outcomes = (1,2,3,4,5,6) = 6

P(rolling a six) = 1/6

P(rolling a 6 and spinning a vowel) = 1/3 * 1/6 = 1/18

Answer:

[tex]\sin \theta = 0.153[/tex], [tex]\cos \theta = 0.988[/tex], [tex]\tan \theta = 0.155[/tex], [tex]\cot \theta = 6.462[/tex], [tex]\sec \theta = 1.012[/tex], [tex]\csc \theta = 6.538[/tex]

Step-by-step explanation:

Let be the point [tex](x,y)[/tex], the six trigonometric functions of the angle are represented by following formulas:

[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex] (1)

[tex]\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex] (2)

[tex]\tan \theta = \frac{\sin \theta}{\cos \theta} = \frac{y}{x}[/tex] (3)

[tex]\cot \theta = \frac{1}{\tan \theta} = \frac{x}{y}[/tex] (4)

[tex]\sec \theta = \frac{1}{\cos \theta} = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex] (5)

[tex]\csc \theta = \frac{1}{\sin \theta} = \frac{\sqrt{x^{2}+y^{2}}}{y}[/tex] (6)

If we know that [tex]x = 84[/tex] and [tex]y = 13[/tex], then the values of the six trigonometric functions is:

[tex]\sin \theta = \frac{y}{\sqrt{x^{2}+y^{2}}}[/tex]

[tex]\sin \theta = 0.153[/tex]

[tex]\cos \theta = \frac{x}{\sqrt{x^{2}+y^{2}}}[/tex]

[tex]\cos \theta = 0.988[/tex]

[tex]\tan \theta = \frac{y}{x}[/tex]

[tex]\tan \theta = 0.155[/tex]

[tex]\cot \theta = \frac{x}{y}[/tex]

[tex]\cot \theta = 6.462[/tex]

[tex]\sec \theta = \frac{\sqrt{x^{2}+y^{2}}}{x}[/tex]

[tex]\sec \theta = 1.012[/tex]

[tex]\csc \theta = \frac{\sqrt{x^{2}+y^{2}}}{y}[/tex]

[tex]\csc \theta = 6.538[/tex]

Answer:

3024.

Step-by-step explanation:

9! / 5!

=  9*8*7*6*5*4*3*2*1

   -------------------------

         5*4*3*2*1

We can cancel out  the 5*4*3*2*1 to give:    

9*8*7*6

=  3024

Step-by-step explanation:

Answer:

X=-5, y=1

Step-by-step explanation:

Add 3x+-3x to get 0. You are left with

-3y=12

4y=-11

add together

y=1

substitute1 in either equation to solve for x

-3x-3y=12

-3x-3(1)=12

-3x-3=12

-3x=15

x=-5

Answer:

A theater group has 7 boys and 19 girls. What is the ratio of girls to the entire group?

Step-by-step explanation:

One ratio problem would be:

A theater group has 7 boys and 19 girls. What is the ratio of girls to the entire group?

In order to solve this problem we would first need to calculate the total number of individuals in the theater group. We do this by adding the number of boys with the number of girls.

7 + 19 = 26

Now since we know there are 19 girls, the ratio would be 19 girls for every 26 individuals, or in ratio format it would be ...  19 : 26

Part A: Group A is a cluster of points. Group B Is not even a group this point is an outlier. A possible reason Point B is involved is because there could be a student that although played a lot of video games, he studied too and got a good score.  

Part B: The association is a negative linear association. Also as students play more video games the test scores tend to go down.

Hope This Helps!

Answer:

Part A: A is a cluster and B is an outlier. I think it is there to show that  even kids who play lots of games can get good grades.

Part B: So, if they play too many games, the grades go down, but not all the time
