Answer:
B) 0.40
Step-by-step explanation:
m = 1.85
l = 1.85 + c
With 5 medium drinks and 5 large drinks:
C = 5m + 5l
20.5 = 5(1.85) + 5(1.85 + c)
20.5 = 9.25 + 9.25 + 5c
20.5 = 18.5 + 5c
5c = 20.5 - 18.5
5c = 2
c = 2/5 = 0.4
If 150 chocolate chip cookies are 15% of the days production, then we may write it down as:
150 = 15% from x
150 = 15/100x
150 = 3/20x / * 20 (both sides)
3000 = 3x / ÷ 3 (both sides)
<u>x = 1000</u>
Answer: I planned producing 1000 cokies that day.
Answer:
First of all, the answer is E.
Step-by-step explanation:
Based on the graph, comment what you think for 2. X axis is number of cones, y is cost of the cones. ;)
Answer:
<h2>y = x + 2</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept → (0, b)
The formula of a slope:
============================================
We have the points (0, 2) → b = 2 and (4, 6).
Calculate the slope:
Substitute the values of the slope and the y-intercept to the equation of a line:
The distance can be found with integ (v(t)= integ(49 _ 9.8t= 49t _ 9.8 /2 t^2
so D(t) = 49t _ 9.8 /2 t^2, for t = 10s, D = 49x10 _ 9.8 /2 x 100 =441
D = 441
