Answer:
2R^2 + 21R - 36
Explanation:
To answer this question, we will follow these steps:
1- expand the brackets
2- gather like terms
Steps are as follows:
(2R-3)(R+12) = 2R(R) + 2R(12) - 3(R) - 3(12)
= 2R^2 + 24R - 3R - 36
= 2R^2 + 21R - 36
Hope this helps :)
Hmm... well, the 10-pack of 2.1 ounce bars cost $15.37:
So that means the price per bar is: 15.37/10 = $1.537
The price per ounce would be: 15.37/(10×2.1) = $0.73
For the 12-pack of 1.4 ounce bars that cost $15.35:
The price per bar is: 15.35/12 = $1.28
The price per ounce is: 15.35/(12×1.4) = $0.91
In other words, the 12-pack has the better price per bar.
Although, the 10-pack has the better price per ounce.
Answer:
Step-by-step explanation:
Let J = John's share ($)
P = Peter's share ($)
H = Henry's share ($)
1) H = P + 80
2) J/P = 6/3 = 2
3) P/H = 3/5
Substitute equation 1) into equation 3)
P/(P + 80) = 3/5 (multiply both sides by (P + 80)
P = (3/5)*(P + 80) (multiply both sides by 5)
5*P = 3*P + 240
2*P = 240
P = 240/2 = $120
Substitute P value into equation 2)
J/P = 2 or
J = 2*P = 2*$120 = $240
John received $240
∠A is called inscribed angle. Inscribed angle is made from a point that attaches to the circle's circumference.
∠BOC is central angle. ∠BOC and ∠A are facing to the same side and because they are facing to the same side, they apply the rule of
inscribed angle = 1/2 × central angle
So we can find ∠A with this property
∠A = 1/2 × 132°
∠A = 66°
