Answer:
V=65.94 in^3 (inches cubed)
Step-by-step explanation:
V=πr^2h/3
h = 7
r = 3
V = (3.14)(3^2)(7/3)
V= (3.14)(9)(2.333)
V=65.94 in^3
Answer:
It is:
86387.13241
Step-by-step explanation:
Solving a linear equation, we can conclude that each tin costs £0.75
<h3>How much does a tin of beans cost in pounds?</h3>
First, we know that Ed buys one box of eggs for £2.20.
Also two packs of bacon for £2.80 each.
And two tins of beans for X each.
Then the total cost is:
C = £2.20 + 2*£2.80 + 2*X
Now, we also know that when he pays with £10, he gets a change of £0.70.
Then we can solve the linear equation:
£10 - (£2.20 + 2*£2.80 + 2*X) = £0.70
£2.20 - 2*X = £0.70
£2.20 - £0.70 = 2*X
£1.50 = 2*X
£1.50/2 = X = £0.75
In this way, we can conclude that each tin costs £0.75

You use tan34=x/15
so x=15*tan(34degrees)
x=10.12 ft
Since x is the number of seconds it took the rock to hit the water, x is the value that we are looking for. When the rock hits the water, it's height is 0, therefore, f(x) = 0. So, we can set the expression on the right equal to 0, and solve for 0. Let's do just that:

We can divide by -16, nothing will happen because 0 divided by anything is 0:

To factor any trinomial in standard form (given below), we must find two numbers that add to "b" and multiply to "c":

So, for this specific question, let's find two numbers that add to -8 and multiply to 9. These are clearly 9 and -1. We can write it in this way now:

Both answers would be valid, but there can't be negative time, so your answer is
"It takes 9 seconds for the rock to reach the water."
