Answer:
1st Option
Step-by-step explanation:
All angles in a triangle must add up to 180°.
Step 1: Set up equation
40° + 60° + 16x = 180°
Step 2: Rewrite
60° + 16x + 40° = 180°
Answer:
1. 15
2. -23
3. -16
Step-by-step explanation:
1. Find h(-8)
h(t) = 
h(-8) = 
h(-8) = 
2. What is the value of g(-3)
g(x) = 4(x - 5) + 
g(-3) = 4(-3 - 5) 
g(-3) = 4(-8) + 9
g(-3) = -32 + 9
g(-3) = -23
3. Find f(10)
f(x) = 14 - 3x
f(10) = 14 - 3(10)
f(10) = 14 - 30
f(10) = -16
A = 31 degree
Cos 31 degree = 400/x
X = 400/ Cos 31
= 400/0.8572
= 466.7ft
Answer:
140
Step-by-step explanation:
we know that this year the sports club has 25% less memeber, so if last year the members where 100% this year there are only 75%
and that 75% is equal to 105 members
we can represent the information that we are given in a table:
memebers percentage
105 ⇒ 75%
since last summer there were the 100% of member we can represent the number of members from last summer with 'x', and the table now is:
memebers percentage
105 ⇒ 75%
x ⇒ 100%
and we use rule of three to solve this problem: multiply cross quantities (105 by 100) and divide by the remaining amount:
x = 105*100/75
x = 140
Last summer the sports club had 140 members
According to my study B (-4, 1) is the answer
