Answer:
18 ounces
Step-by-step explanation:
4 pounds is 64 ounces. 2 pounds is 32 ounces.
- First, you subtract the 32 ounces of grape tomatoes from 64. That leaves you with 32.
- Next, subtract 14 ounces of roma tomatoes from 32. You get 18.
- That means he bought 18 ounces of plum tomatoes.
Good evening
Answer:
Step-by-step explanation:
g(x) = -20
⇔
3x-1 = -20
⇔
3x = -20 + 1
⇔
3x = -19
⇔
x = -19/3

Answer:
We need to find the zeros.
4x^4 + 8x^3 - 7x^2 -21x - 9
You're supposed to use synthetic division, assuming you're in algebra 2. I removed my calculus work.
x = -1 1/2, 1+sqrt5/2 , 1-sqrt5/2
x= -1.5000000119775176
4x 4 + 8x 3 - 7x 2 - 21x - 9= 0
x= -0.618033988749895
4x 4 + 8x 3 - 7x 2 - 21x - 9= 0
x= <u>1.618033988749895</u>
4x 4 + 8x 3 - 7x 2 - 21x - 9= 0
Answer:
a) 18 grapefruits
b) 6 grapefruits
Step-by-step explanation:
a) n = 14.4 / 0.80 = 18 grapefruits
b) n = (14.4 / 3) / 0.8 = 6 grapefruits
An equilateral triangle isn't a right triangle, so the Pythagorean Theorem doesn't apply directly.
But if we divide an equilateral triangle with side <em>s</em> in half along an altitude, we get two congruent right triangles each with hypotenuse <em>s </em>and one leg <em>s/2.</em>
The other leg is the altitude <em>h</em> we divided along. By the Pythagorean Theorem
The area <em>A</em> of our original equilateral triangle is now
So the area of our equilateral triangle of side 5 is
Answer: 10.8
I don't like ruining a nice exact answer with an approximation, but the question asks for one.
We could have done the above steps with 5 in particular instead of <em>s </em>but I prefer to do the general solution and substitute at the end.

Since you read this far, I will give you the secret formula for the area S of a triangle given <em>squared</em> sides A, B, C. Your teachers won't even know this one.
Let's try it out for an equilateral triangle:
