Answer:

school x = 12

school y = 4

Step-by-step explanation:

School X has eight more points than School Y.

School X has three times as many points as School Y .

Writing these statements in terms of equation 

x = y + 8  

 x = 3 y

Substituting the value of x in y, we get

3 y = y + 8

Taking variable on left side of equation

3 y – y = 8 (subtract y from both sides)

2 y= 8 (divid 2 from both sides)

y = 4

then plug in y to the first equation

x= y + 8

x= 4 + 8

x= 12

Step-by-step explanation:

Parallelogram is a quadrilateral whose both pairs of opposite sides are parallel and equal and opposite angles are also equal.

[tex] \: [/tex]

So,

[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { \angle P = \angle R}}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \pmb{ \sf { 6x - 10 = 2x + 50}}}} \: \: \\ \\[/tex]

Subtracting 2x from both sides we get :

[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { 6x - 10 - 2x = 2x + 50 - 2x}}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \pmb{ \sf { 4x - 10 = 50 }}}} \: \: \\ \\[/tex]

Adding 10 to both sides we get :

[tex] \\ { \longrightarrow \qquad{ \pmb{ \sf { 4x - 10 + 10 = 50 + 10 }}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \pmb{ \sf { 4x = 60 }}}} \: \: \\ \\[/tex]

Dividing 4 from both sides we get :

[tex]{ \longrightarrow \qquad{ \pmb{ \sf { \frac{4x}{4} = \frac{60}{4} }}}} \: \: \\ \\[/tex]

[tex]{ \longrightarrow \qquad{ \pmb{ \frak { x = 15 }}}} \: \: \\ \\[/tex]

Therefore,

Answer:

If the 7 x 2 is in parenthesis then you would do the 7 x 2 first then do 14 by the power of 3. If there is no parenthesis and the power of 3 is hovering next to the 2 then you would do 2 to the power of 3 and then multiply that by 7.

Step-by-step explanation:

PEMDAS. Whatever is in parenthesis gets solved first, then exponents and so on and so forth.

The model that can be used to determine the total amount of prize money based on the value of the first place prize is as follows;

Total amount of price money = 5x - 500

The prices are given to the best 5 acts. The first place wins the most money and each place after that wins $50 less than the previous place. The pattern follows a sequence.

Sequence  is a list of things (usually numbers) that are in order. Therefore,

let

the first price = x

The common difference of the sequence would be - 50.

To create a model that can be used to determine the total amount of prize money based on the value of the first place prize can be done as follows;

Therefore,

Total amount of price money = x + x - 50 + x - 100 + x - 150 +  x - 200

Total amount of price money = 5x - 500

Step-by-step explanation:

Answer: 3/4

Step-by-step explanation:

The probability that you will land on either red or blue is equal to the sum of the probability that you will land on red and the probability you will land on blue.

The probability you will land on red is 1/2 and the probability that you will land on red is 1/4 by the image.

Therefore, the probability you will land on either is 1/4 + 1/2 = 3/4

Answer:

18 yd 2 ft

Step-by-step explanation:

56÷3=18 R2

18x3=54+2=56

Answer:

56 ft = 18 yd and 2 ft

Step-by-step explanation:

3 feet = 1 yard

Therefore, to find how many yards and feet are in 56 yards, divide 56 by 3:

⇒ 56 ÷ 3 = 18 remainder 2

Therefore,  

56 ft = 18 yd and 2 ft

Answer:

12/17

Step-by-step explanation:

total number of marbles that are purple (11) plus the total number of marbles that are not small (15) minus the number of marbles that are both purple and not small (2)

11 + 15 - 2 = 24

over the total number of marbles (34)

24/34 simplifies to 12/17

answer 13/17

Step-by-step explanation:

you add all the numbers up in the table, which would be 34 and then add up the ones that are big and the ones that are purple, which would be 26 so 26/34 then you simplify.

so 26/34=13/17

The best representation of the population is; C. Ask 100 parents at the local playground

In statistics, a population is the entire group that you want to draw conclusions about. Whereas, a sample is the specific group that you will collect data from.

Now, the family committee want to select a movie that will appeal to families with young children. Thus, it will be best for them to ask the parents of children as that will be a true representation of what the families would like to watch.

In conclusion, the only correct option is option C to ask 100 parents at the local playground

Step-by-step explanation:

Let find the other trig function first, just sin s and sin c.

Use pythagoren identity to find sin a.

[tex]1 - \cos {}^{2} (s) = \sin {}^{2} (s) [/tex]

cos s=3/5 so cos^2(s)=9/25

[tex]1 - \frac{9}{25} = \sin {}^{2} (s) [/tex]

[tex] \frac{16}{25} = \sin {}^{2} (s) [/tex]

[tex] \frac{4}{5} = \sin(s) [/tex]

Since this is in the first quadrant, it is positve.

Let do the the same thing for sin t.

[tex]1 - \frac{169}{289} = \sin {}^{2} ( {}^{} t) [/tex]

[tex] \frac{120}{289} = \sin {}^{2} (t) [/tex]

[tex] \frac{2 \sqrt{30} }{17} = \sin(t) [/tex]

Now, we can compute

a.

[tex] \sin(s + t) = \sin(s) \cos(t) + \cos(s) \sin(t) [/tex]

[tex] \frac{4}{5} \times \frac{13}{17} + \frac{3}{5} \times ( \frac{2 \sqrt{30} }{17} )[/tex]

[tex] \frac{52}{85} + \frac{6 \sqrt{30} }{85} [/tex]

[tex] \sin(s + t) = \frac{52 + 6 \sqrt{30} }{85} [/tex]

b

[tex] \tan(s + t) = \frac{ \tan(s) + \tan(t) }{1 - \tan(s) \tan(t) } [/tex]

Tan s is 4/3

Tan t is 2 times root of 30/ 13

So we have

[tex] \frac{ \frac{4}{3} + \frac{2 \sqrt{30} }{13} }{1 - \frac{8 \sqrt{30} }{39} } [/tex]

[tex] \tan(s + t) = \frac{52 + 6 \sqrt{30} }{39 - 8 \sqrt{30} } [/tex]
