In a school of 464 students, 89 students are in the band, 215 students are on sports teams, and 31 students participate in both activities. How many students are involved in neither band nor sports?
A.160 students
B.191 students
C.249 students
D.433 students
Answer:
191 students B option is correct
Step-by-step explanation:
Total students=464
In band=89
sports teams=215
Number of students who participates in activities is
215+89=304
31 participate in both activities so,
304-31=273
273 who participate in activities
Total students-273=Not involved in any activity
464-273=191
2(x - 3) = 2x + 5? Need Help Now
Answer: it has no solutions
Step-by-step explanation:
if im wrong i owe u
2(x - 3) = 2x + 5 distribute by multiply 2 into the parenthesis.
2x - 6 = 2x + 5
-2x -2x subtract 2x on both sides, 2x's will cancel on both sides.
____________
-6 = 5
Since -6 = 5, there is no solution because -6 cannot equal to 5, which is a false statement. Thus, "C. There is no solution." is the correct answer. Hope this helps :)

A local paintball facility charges $30 to play plus $0.25 per paintball pellet used. Elijah plans on playing paintball and has $60 to spend at the facility. Which equation can be used to determine p, the number of paintball pellets he can use if he spends exactly $60?
A. 30 + 0.25p = 60
B. 30 + 0.25 = 60p
C. 30p + 0.25 = 60
D. 30 − 0.25p = 60
Step-by-step explanation:
Hello! I believe the answer is A. 30+0.25p=60.
Elijah has to pay a facility charge which is 30$. So we can go ahead and write that down! He has 60$ to spend, but he has to pay $0.25 per paintball. So we write that as 30+0.25p=60!! If you have any questions comment doen below!

(c) The annual membership fee in 2013 is $198 for each adult and $75 for each child.
Adult = 440 members
Children = 120 members
(i) Calculate the total amount the 560 members pay in 2013.
(ii) The adult fee of $198 in 2013 is 5.6% more than the fee in 2012.
Calculate the adult fee in 2012.
Answer:
i ) $96120
ii ) Singular adult fee in 2012: $186.91
Step-by-step explanation:
( i )
To find the costs of all 560 peoples you:
Multiply the amount of people by the fee,
440 × 198 = $87120
120 × 120 = $9000
Add these go get the sum of member fees: $96120
( ii )
First calculate what 1% of the adult fee would be:
198 ÷ 100 = 1.98 = 1%
Then calculate what 0.1% of the fee:
1.98 ÷ 10 = 0.198 = 0.1%
Now multiply 5 by the value of 1% to get 5% :
5 × 1.98 = 9.9
Then multiply 6 by the 0.1% to get 0.6% :
0.198 × 6 = 1.188
Add these numbers together to get:
1.188 + 9.9 = $11.088 = 5.6%
Due to the fact this question is referring to money we will round this number 2 decimal places (as money does not exceed 2dp)
$11.09
We now subtract this from the 2013 fee to find out the 2012 fee
$198 - $11.09 = $186.91
$186.91 was the cost of a singular adult fee in 2012

Solve for angle B, then side a. Round to the nearest tenth.
Answer:
Angle B: 28 degrees
Side a: 27.6
Step-by-step explanation:
Angle B:
180-112-40=28
Side a:
sin 28/14 = sin 112/a
a = sin 112(14)/sin 28
a = 27.6

Answer:
[tex] \frac{x - 10}{8} [/tex]
Step-by-step explanation:
[tex] \frac{3x}{8} - \frac{x + 5}{4} [/tex]
The common denominator of both fractions is 8. Therefore,, divide the denominator of each fraction, then multiply what you get by the numerator of each fraction.
Thus:
[tex] \frac{1(3x) - 2(x + 5)}{8} [/tex]
[tex] \frac{3x - 2x - 10}{8} [/tex]
[tex] \frac{x - 10}{8} [/tex]

Which expression is not equal to 1?
sin θ csc θ
cos θ sec θ
tan θ cot θ
sin θ cos θ
Answer:
sin θcos θ
hope it is helpful to you
Answer:
sin A cos A
Step-by-step explanation:
[ I don't know to type angle theta here so assume A as theta]
As , sin A= p/ h
cos A= b/ h
so,
sinA cosA = p/ h × b/h
= pb/ h^2 ( which is not equal to 1 )
Tip; you can easily verify other relations expressing trigonometric ratios in terms of p,b & h and further simplifying..

In the following triangle, angle A measures 49° and angle C measures
62.
Answer:
The measure of angle B is 69°.
Step-by-step explanation:
All angles of the triangle should add up to 180°, so you add angle A and angle C together, and then subtract that number from 180.
49 + 62 = 111
180 - 111 = 69
69°
