6 adults - 6*39.50= 237
11 kids. - 11*31= 341
341 + 237 = 578
Answer:
f(-1)=3
Step-by-step explanation:
f(x)=x^2-6x+3x-1
f(x)=x^2-3x-1
f(-1)=(-1)^2-3(-1)-1
f(-1)=1+3-1
f(-1)=4-1
f(-1)=3
Answer:
EF=22
C=70°
B=110°
Step-by-step explanation:
Trapezoids have to have a total of 360° and there are complementary angles.
Answer:
Step-by-step explanation:
a/sina =b/sinb=c/sinc =d=sind
250/sin25 = 459/sinb
250sinb = 459sin25 = 459(0.42261826174) = 193.981782139
sin b = 193.981782139/250 = 0.77592712855
b = sin⁻¹0.77592712855 = 50.88916502
I think 24.6 if I’m not right I’m so sorry
