Step-by-step explanation:
Answer:
C
Step-by-step explanation:
< means exclusive, so open hole
≤ means inclusive, so closed dot
also, you can see that the values for y are going down, like 6, 4, 2. That's only in answer C.
=====================================
Explanation:
The reference angle is angle S = 41 degrees. The side opposite that (RT) is unknown and what we want to find. The adjacent side to the reference angle is TS which is 8 units long.
RT = x
TS = 8
The ratio of the opposite and adjacent side is equal to the tangent of the reference angle, so,
tan(angle) = opposite/adjacent
tan(41) = x/8
--------------
We are given the value of tan(41) to be approximately 0.869, which means we will replace "tan(41)" with this decimal value and then isolate x by multiplying both sides by 8. This happens in the section below.
--------------
tan(41) = x/8
0.869 = x/8
8*0.869 = 8*x/8
6.952 = x
x = 6.952
x = 6.95
RT = 6.95
There are 71 students in the marching band.
Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that one-sixth of the girls and two-sevenths of the boys in a school marching band are in the percussion section. The percussion section has 6 girls and 10 boys.
Let the total number of girls in the band be y and that of boys x;
Then;
1/6y = 6
y=6 x 6
y= 36
There are 36 girls in the school.
2/7x = 10
2x = 10 x 7
2x = 70
x = 70/2
x=35
Therefore, there are 71 students in the marching band.

I was doing a past paper and came across this,I know one (long) way of doing this and was just wondering if anyone could show me a shorter way!!!
