Answer:
Given: In ΔABC ,
To prove that:
[Given]
In ΔADB
The sine angle is defined in the context of a right triangle is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle.
[By definition of sine] .....[1]
Multiplication Property of equality states that you multiply both sides of an equation by the same number.
Multiply by c to both sides of an equation [1] we get;
Simplify:
......[2]
Now, In ΔACD
Using definition of sine:
Multiply both sides of an equation by b;
[Multiplication Property of equality]
Simplify:
......[3]
Substitute [3] in [2];
......[4]
Division property of equality states that if you divide both sides of an equation by the same nonzero number the sides remains equal.
[4] ⇒
Therefore, the missing statement in step 6 is;
Assuming that both measurements are the areas, you have 150yds^2 of carpet to cover y rooms with each room needing 12 3/4^2 of carpet.
(If it confuses you, ignore the ^2 because it helps me understand what I'm doing)
For me, it's easier to convert fractions to decimals. 12 3/4 = 12.75
So now you have this equation: 12.75 × y = 150
In algebra, you want to isolate the y, aka the unknown variable. To do so, you need to divide each side by 12.75.
12.75 × y = 150
------------ ------
12.75. 12.75
On the left, you can cross out the 12.75 because it's divided by itself, thereby making it 1. There's no need to have 1y, it's just y. On the other hand, you divide 150 by 12.75, which equals 11.7647059.
Now you might assume to round up this number, making it 12 rooms, but it simply doesn't work. You would have 11 complete rooms and one partially covered room. Therefore, your answer is y = 11 rooms.
Answer: You can cover 11 rooms.
Hope this helps, have a wonderful day. :)
Answer:
A=4 B=-8 C=-3
Step-by-step explanation:
first you must but in the form ax^2+bx+c you get 4x^2-8x-3 so a=4 b=-8 c=-3
Read it carefully. It's telling you the answer in the problem! There is one teacher for every 11 students. Of course there are more students!
