Answer: 10x-33
Step-by-step explanation:
Start to subtract 4a - 3a - 5a ok you should get 2a then subtract 7c - 2c then you should get 5c then don't add cause u cant but your answer is
5c + 2a this is your answer
330
20 * 6 equals 120 that is the cost price
and 3/5 of the 15 flowers is 9 which was sold for 7
and the remaining that is 15 - 9 that's 6 sold for 50 each
now times it by 70 * 9 equals 630 50 * 6 equals 300 so 630 - 300 equals to 330 that is the profit
I hope this helps
Answer:
A
Step-by-step explanation:
Since DE is parallel to AB and intersects the other 2 sides, it divides those sides proportionally, that is
=
Note that AD = 33 - 22 = 11
Substitute values into the ratio
= = ( cross- multiply )
2x = 16 ( divide both sides by 2 )
x = 8
To find y use similar triangles
Δ ABC is similar to Δ DEC, thus ratios of corresponding sides are equal
= , substitute values
= = ( cross- multiply )
3y = 36 ( divide both sides by 3 )
y = 12
Thus y = 12, x = 8 → A
Answer: the gun was held 4ft high i.e H = 4ft
Step-by-step explanation:
To determine how high the gun was held when it was fired H;
Before firing the t-shirt up, the gun and the t-shirt are both at the same height.
Therefore,
H = h(0) i.e h(t) at t = 0
h(t) = -16t^2 + 64t + 4
H = h(0) = -16(0)^2 + 64(0) + 4
H = 4ft
