25% off translates into 0.25($30) = $7.50 off.
A faster way to determine the sales price is to subtract 0.25 from 1.00 and then mult. the regular price by the result: sales price = 0.75($30) = $22.50 (answer)
Answer:
339.3inches^3
Step-by-step explanation:
Volume of cylinder V = πr²h
The diameter is constant, so the radius is half of the diameter = 12/2 = 6 inches
It can be seen that the height has been divided into three in the ratio 3:2:1
The height of the strawberry section is 1/6 × 18 = 3 inches.
Now, we calculate the volume of the strawberry section as follows:
π = 3.142
r = 6 inches
h = 3 inches
V = 3.142 × (6)^2 × 3 = 339.336 inches^3
This converted to the nearest tenth is 339.3 inches^3
Y = 3x + 4....slope here is 3. A parallel line will have the same slope.
slope = (d - 4) / (5 - (-2) = (d - 4) / (5 + 2) = (d - 4) / 7....so d is going to have to be 25.
lets check....the slope has to equal 3 to be a parallel line
(-2,4)(5,25)
slope = (25 - 4) / (5 - (-2) = 21/(5 + 2) = 21/7 = 3 (correct)
so d = 25
Answer:
18
Step-by-step explanation:
f(x)=2x and g(x)=x2+3, find (g ∘ f)(−3)
f(x)= 2(-3)= -6
g(x)= (-3)(2) +3= -6+3= -3
(g ∘ f) = -6 x -3= 18
