7 0

If you would like to solve the equation b^2 + 9 * b + 18 = 0 for the variable b, you can do this using the following step:

b^2 + 9 * b + 18 = 0
(b + 3) * (b + 6) = 0

Result:
1. solution: b = - 3
2. solution: b = - 6

Answer:

$284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

Step-by-step explanation:

Firstly, to calculate the portions each class should have, we should find the proportion each class takes up.

Hence, let's say A represents Mr. Aceves' class, B represents Mrs. Baca's class, and C represents Mr. Canyon's class.

The total number of box tops collected would be 3760 + 2301 + 1855 = 7916 box tops.

Therefore, the total proportions would be:

A = $\frac{3760}{7916}$

B = $\frac{2301}{7916}$

C = $\frac{1855}{7916}$

Hence, we can finally multiply these proportions with the total prize to find the appropriate division:

Mr. Aceves' class gets $\frac{3760}{7916} \cdot 600 \approx 284.99$ .

Mrs. Baca's class gets $\frac{2301}{7916} \cdot 600 \approx 174.41$ .

And Mr. Canyon's class gets $\frac{1855}{7916} \cdot 600 \approx 140.60$ .

Finally, $284.99 should go to Mr. Aceves’ class, $174.41 should go to Mrs. Baca’s class, and $140.60 should go to Mr. Canyon’s class.

Hope this helped!

((60 * c) + 3300 ≤ 24000

60c ≤ 24000 - 3300

60c ≤ 20700

c ≤ 20700 / 60

c ≤ 345

We know, widest angle is always opposite to the largest side of the triangle, as largest side is 50 here (which is backward to house) so largest angle would be opposite to it. So, that corner will be touched by Fence A & B

"Proportionality Theorem" compares the sides of the same triangle
Here, According to that theorem,
ST / RS = UT / PU

If FG is an altitude, then <DFG is an right triangle.
In short, Your Answer would be Option B

For last question here, remember, longest side must be greater than either side, and must be smaller than sum of those smaller sides.
