Answer:
Let x = # of hot dogs sold
Let x + 31 = # of sodas sold
For the total, do: x + x + 31 = 173
2x + 31 = 173
-31 -31
2x = 142
Divide out both sides by 2; to get: x - 71
That gives us 71 hot dogs; and 71 + 31 = 102 sodas
To test this: 71 + 71 + 31 = 173
173 = 173 [Check]

60% of the students in a school of 800 students take a bus. how many students take the bus?
Answer:
480
Step-by-step explanation:
60% of 800
= [tex]\frac{60}{100}[/tex] × 800
= 0.6 × 800
= 480 ← number of students who take the bus
using the spinner above, what is the probability that you will land on red or blue?
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

Find the value of X for the given parallelogram
Answer:
15[tex] \: [/tex]
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]

School X and School Y play eachother in a competiton.
School X has eight more points than School Y
School X has three times as many points than School Y
How many points does each school have?
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
Use the given information to find (a) sin (s +t), (b) tan (s+t), and (c) the quadrant of s+t cos s=3/5 and cos t= 15/17, s and t quadrant I
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]
c. They are all in 1st quadrant

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
Which operation should you perform first in the expression 7 × 2 by the power of 3
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.

A high school is having a talent contest and will give different prizes for the best 5 acts in the show. First place wins the most money, and each place after that wins $50 less than the previous place. Part A Create a model that can be used to determine the total amount of prize money based on the value of the first place prize Enter your model in the box provided.
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.
What is 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;
x , x - 50, x - 100, x - 150, x - 200Therefore,
Total amount of price money = x + x - 50 + x - 100 + x - 150 + x - 200
Total amount of price money = 5x - 500
