£1.50/5=£0.30
So one cake costs £0.30.
£0.30x7=£2.10
So the answer is £2.10.
Answer:
0.40 or 40%
Step-by-step explanation:
Assuming that no student can hold a position at two companies simultaneously, the probability of a student interning at Hawaiian Airlines or Big Island Candies is simply determined by the sum of each individual probability:
![P(H\ or\ B) = P(H)+P(B)\\P(H\ or\ B) = 0.30+0.10 = 0.40 =40\%](https://tex.z-dn.net/?f=P%28H%5C%20or%5C%20B%29%20%3D%20P%28H%29%2BP%28B%29%5C%5CP%28H%5C%20or%5C%20B%29%20%3D%200.30%2B0.10%20%3D%200.40%20%3D40%5C%25)
There is a 40% chance that a student interns at Hawaiian Airlines or Big Island Candies.
Answer:
y = 20
x = 120
Step-by-step explanation:
2x + 3y = 300
3x + 5y = 460
mutliply eqn 1 by 3 and 2 by 2
6x + 9y = 900
6x + 10y = 920
y = 20
x =
A² + 2ab + b² ; Solve when a=10 & b=50
Simply plug in 10 for a and 50 for b in our given equation :)
(10)² + 2(10)(50) + (50)²
Simplify.
100 + 20(50) + 2500
Simplify.
(100 + 2500) + 1000
Simplify.
2600 + 1000
Simplify.
3600
Hope I helped! :)
