Answer:
C
Step-by-step explanation:
note that sin x = cos(90 - x ) ← Cofunction identity
If x = 36 then 90 - x = 90 - 36 = 54
Hence sin 36° = cos 54° → C
Answer:
to find the adverage you have to add the times together then divide them by 2 so 2 + 1.5 = 3.5/2= 1.75
Step-by-step explanation:
Answer:
x= 13/22
Step-by-step explanation:
you can substitute y= 34 x on the second equation
34x = -54x +52 add 54x to both sides
34x +54x = -54x +54x +52
88x = 52 divide both side by 4
22x = 13 divide both sides by 22
x= 13/22

Answer:
238
Step-by-step explanation:
Start with Raven's ants since hers is the one that everyone else's is based off of.
Raven = 208
Haley has half of that plus 76, so
Haley = (208/2) + 76
Haley = 180
If Haley's farm doubles in population, she would have 360 ants. That number is equal to Nate's number + 122. We have an equation of sorts there to solve for Nate's ants:
180(2) = N + 122 so
360 = N + 122 and
N = 238
Nate has 238 ants in his farm.
