40 cents is the answer but brainy asked me to add some more words. How u doing?
Answer:
26
Step-by-step explanation:
Basically when the equation is adding you subtract from each side of the equation....
So:
x + 40 = 75
-40 = -40
75 - 40 = 26
x = 26
Answer:
350.17 pounds
Step-by-step explanation:
Set up an equation where x is the weight of the tuna from bout B:
1305 = 6x - 796
Solve for x:
2101 = 6x
350.17 = x
So, the weight of the tuna is approximately 350.17 pounds
We have that
(r, ∅)----------> (-7, <span>5 pi/3)
we know that
</span>5 pi/3--------> 300°-----------> -60°
To convert polar cordinates in rectangular one with use the following formula:
x=r*cos ∅------> x=-7*cos -60°-------> x=-7*(1/2)------> x=-7/2
y=r*sin ∅-------> y=-7*sin -60-------> y=-7*(-√3)/2----> y=7√3/2
the answer is the option
D) ordered pair negative 7 divided by 2 comma 7 square root 3 divided by 2
Hi there!
To solve this problem, we need a few things. We need the formula for the area of a circle and a bit of knowledge about squares and square roots. The area of a circle is equal to A = pi * r^2. Using this formula, we can set the area equal to the other part of the formula to solve for the radius, r. Then, we can double the radius because the diameter is equal to the radius doubled.
WORK:
49pi = pi * r^2 (Setting up an equation)
49 = r^2 (dividing both sides by pi)
r = 7 (finding the square root of both sides)
d = 14 ft (doubling the radius)
Hope this helps!! :)
If there's anything else that I can do for you, please let me know!
