W=15 subtract 80 from both sides than you divide by -2w
Answer:
30 feet
Step-by-step explanation:
A ratio of 4:3 means that if one part can be represented by x, the original height is equal to 4 * x and the mural height is equal to 3 * x. This is because the ratio of original : mural is 4 : 3, so if one part = x, we have 4 * x : 3 * x. Therefore,
original mast height = 40 feet
4 * x = original mast height = 40 feet
divide both sides by 4 to get x
x = 10 feet
3 * x = mural mast height = 3 * 10 feet = 30 feet
Answer:
2
Step-by-step explanation:
The question is asking what the value of <em>f(x)</em>, or <em>y</em>, is when <em>x</em> equals -2.
When <em>x</em> = -2, <em>y</em> = 2. Therefore, f(-2) = 2.
Answer:
Hey,
so first off we need to know our equation for the area of a circle;
A=πr2
So know we plug in what we already know,
sense the diamiter we can figure out the radius (half way across) by simply dividing 18 units by 2 which is 9.
Now we have
A=π9²
That is your answer π9²
Answer:
Step-by-step explanation:
you multiply across, so you do 2*2 for the numerator, then 3*3 for the denominator. This would equal 4 as the numerator, 9 as the denominator, which is
