Which proportion could be used to find the length of side b?
6
720
859
A
6.2
Answers
Answer: Choice C) [tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]
=========================================================
Explanation:
The angle opposite side b is 85 degrees. So we'll involve either the fraction [tex]\frac{\sin(85)}{b}[/tex] or [tex]\frac{b}{\sin(85)}[/tex]. In this case, we will use the first fraction. This is due to all of the answer choices having sine on top.
The other fraction must have sine on top as well.
The known side is AB = 6.2; the opposite angle is C = 23 which you find by solving A+B+C = 180 and plugging in A = 72 and B = 85.
So the other fraction we'll use is [tex]\frac{\sin(23)}{6.2}[/tex]
Overall, the proportion we can set up is
[tex]\frac{\sin(23)}{6.2} = \frac{\sin(85)}{b}[/tex]
which points to choice C as the final answer.

She needs to buy

bat bags. The coach
Choose...(does not, does.)
have enough money to buy a bat bag for each player.
Answers
Answer:
11
12
does not
Step-by-step explanation:
If we know how much money the coach has and how much each bag costs we can find out how much bags the coach can by by divide the money the coach has by the price of one bat bag. So we do....
605 / 55 = 11
So now we know that she can by 11 bags maximum, while she needs 12 bags for the team. From this we know that she does not have enough money to buy 12 bags.

Answer:
The value of the expression when x = -1 and y = 2 is -16.
Step-by-step explanation:
Firstly, let's look at [tex]x^{3}[/tex].
As the question provides, the value of x is -1. Therefore, we have to find the value of [tex](-1)^{3}[/tex], which is -1.
Now, moving onto [tex]y^{2}[/tex].
The question provides us with y = 2. Simply substitute this value into [tex]y^{2}[/tex], and we get [tex]2^{2} = 4[/tex].
Finally, concluding the equation, we get 4(-1)(4). That is equal to -16, which is our answer.

Yesterday, Jack drove 35 1/2 miles used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon?
Answers
Answer:
28.4 miles/gallon
Step-by-step explanation:
to find the answer, you need to find the constant by dividing the miles drove by the amount of gasoline (or the other way around in terms of wording if it is not correct grammar) So you need to do 35.5/1.25 . FYI I converted the fraction to decimal. The answer is 28.4 miles/gallon.

- 10x + y = -58
Answers
Answer:
Step-by-step explanation:
given: x-y = 4
x=4+y
given: -10x + y = -58
plug in for x
-10(4 + y) + y = -58
-40 - 10y + y = -58
-9y = -18
y = -18 / -9
y = 2
now plug in 2 for y in the first equation
x-2=4
x=6
There is the solution x=6, y=2 :)
