Answer:
8
Step-by-step explanation:
Given
2² + 10 - 3 × 2 ← evaluate exponent and multiplication
= 4 + 10 - 6 ← evaluate from left to right
= 14 - 6
= 8
This is the concept of trigonometry, the sine, cosine and tangent of 11/6 pi radians will be as follows;
11/6pi=11/6*180=330
thus;
tan 330=-0.5774
sin 330=-0.5
cos 330=-0.8660
Answer:
Option C is correct.
The solution is (3, -1)
Step-by-step explanation:
Substitution
Given the system of equation:
......[1]
......[2]
We can write equation [2] as;
d = e +4 ....[3]
Using substitution method;
Substitute the value of d in equation [1] we have;
Combine like terms;
Subtract 4 from both sides, we get
2e = -2
Divide both sides by 2 we get;
e = -1
Substitute the value of e = -1 in [1] we have;
d +(-1) = 2
d -1 = 2
Add 1 to both sides of an equation;
d = 3
Therefore, the solution for the given system of equation is, (3, -1)
Ans:- 4:12:24
first add the ratios,that is =10
Then find the amount the 1st person payed= 1/10 *40
=4
2nd person payed= 3/10*40=12
3rd person payed= 6/10*40=24
therefore your answer is 4:12:24
