Answers:
- Choice B) y = (1/4)x
- The unit rate is <u> 3.89 </u> dollars per pound. It costs <u> 23.34 </u> dollars for a turkey that weighs 6 pounds.
=====================================================
Explanations:
- Direct proportional equations are always in the form y = kx, where k is some constant. In the case of choice B, we have k = 1/4. Visually, direct proportion equations are always straight lines and go through the origin.
- Divide $34.99 over 9 to get 34.99/9 = 3.88777 approximately. This rounds to 3.89, so it costs $3.89 per pound. That's the unit rate. Multiply this by 6 to get 6*3.89 = 23.34 which is the cost of the 6 pound turkey.
Answer:
b. One in Five
Step-by-step explanation:
To calculate probability, we need to know the formula: ![\frac{Number of Expected outcomes}{Total Number of possible outcomes}](https://tex.z-dn.net/?f=%5Cfrac%7BNumber%20of%20Expected%20outcomes%7D%7BTotal%20Number%20of%20possible%20outcomes%7D)
in this case the probability is given in its decimal form, which is = 0.20
∴ to be able to use our formula easily, we will need to convert the probability to its fraction form.
which is 0.20 =
(<em> to do this, just simply put a 1 under the decimal point and replace the remaining values of 20 with zeroes)</em>
reducing
to its simplest form gives
.
Hence, relating it to our formula, we can see that the number of possible out comes is = 1
and the total number of outcomes = 5.
This means that the probability that the order will execute before the same of closing is the same as 1 in 5
The answer would be 1
Slope formula is y2-y1/x2-x1
8-2/8-2
6/6

Alrighty. If there's 3 angles that are on one linear line, they all must add up to 180, because they would wall be supplementary angles (they all add up to 180).
So, we know that the Angle FCA is 90 degrees, and we know that ACB is 66 since they said so. So, we will add them up, then subtract it from 180. So,
BCD + 66 + 90 = 180
BCD + 156 = 180
BCD = 24
(P.S, that means the angle FCE will be the same because of vertical angle theorem)
