Answer:
The new employee burn <u>1756 cookies</u> in the course of the day.
Step-by-step explanation:
Given:
Mr. Edwards hired a new employee to work in his bakeshop. In one hour, this employee burned 439 chocolate chip cookies, which represented 25 percent of all the cookies the employee burned in that day.
Now, to find the cookies the new employee burn in the course of the day.
Let the cookies the new employee burn in the course of the day be 
Number of chocolate chip cookies new employee burned = 439.
Percent this represented of all the cookies the employee burned in that day = 25%.
Now, to get the cookies the new employee burn in the course of the day we put an equation:
<em>Dividing both sides by 0.25 we get:</em>
Therefore, the new employee burn 1756 cookies in the course of the day.
Answer:
Step-by-step explanation:
There are a few algebraic, geometric, and trig relations you are expected to remember. These come into play in this set of questions.
- vertex form for equation of a parabola: y = a(x -h)² +k, has vertex at (h, k)
- Sine Law relates triangle sides and their opposite angles: a/sin(A) = b/sin(B)
- Cosine Law relates triangle sides and the angle between two of them: c² = a² +b² -2ab·cos(C)
- SOH CAH TOA reminds you of trig relations in a right triangle
- relationships of corresponding sides and angles in congruent and similar triangles: angles are congruent; sides are congruent or proportional.
When solving any problem, the first step is to understand what is being asked. The second step is to identify the relevant information and relationships that can help you answer.
<h3>1)</h3>
You are asked for the equation of a parabola with a given vertex. The vertex form equation will be useful. We can assume a scale factor ('a') of 1.
For vertex (h, k) = (1, -4) and a=1, the vertex form equation is ...
y = a(x -h)² +k
y = 1(x -1)² +(-4)
y = (x -1)² -4
<h3>2)</h3>
You are given 3 sides and want to find an angle. The useful relation in this case is the Cosine Law. (If you wanted to use the Sine Law, you would already need to know an angle.)
<h3>3) </h3>
The mnemonic SOA CAH TOA reminds you that the cosine relation is ...
Cos = Adjacent/Hypotenuse
The side adjacent to angle C is marked 4; the hypotenuse is marked 5. The desired ratio is ...
cos(C) = 4/5
<h3>4)</h3>
The measure x is also the measure of side AB. The similarity statement lists those letters as the first two. It also lists the letters DE as the first two. The other given side in ΔABC is BC, corresponding to side EF in the smaller triangle. Corresponding sides are proportional, so we have ...
AB/DE = BC/EF
x/6 = 10/4
We can find the value of x by multiplying this equation by 6:
x = 6(10/4) = 60/4
x = 15
Please note that BC is the shortest side in ΔABC. This means x > 10. There is only one such answer choice. (No math necessary.)
