Answer:
atleast 12
Step-by-step explanation:
someone donated $10, you use the $10 to buy 5 cakes
the profit is $50
you still need 50 more
10-2= $8 in profits
50/8= 6.25 cakes
5 + 6.25 = 11.25
<u>or atleast 13 if you don't count the $10 in</u>
It is a square trinomial:
4v^2 - 16v + 7 = 0
lets multiply and divide all by 4, the square term coefficient:
(16v^2 - 16(4)v + 28)(1/4) = 0
(4v - 14)(4v - 2)<span>(1/4) = 0
</span>factor 1/4
(4v - 14)(4v - 2)(1/2)<span>(1/2)</span> = 0
and divide each:
(2v - 7)(2v - 1) = 0
Answer:
x=y-44 and x+y=410
Step-by-step explanation:
So, you want to use the equations x=y-44 and x+y=410 when x is Ann's score and y is Ruth's score. This is because x (Ann's score) is Ruth's score (y) but 44 less, so you subtract y-44 to get x. Then x+y would also have to equal 410 so that's the other equation. Graphing the 2 equations gets you to the point (183,227) in which Ann's score is 183 points and Ruth's score is 227 points.
A statement that best describes the term "salary" could be: "Salary is best described as a fixed amount of income that is paid to an individual weekly, bi-weekly, or a monthly basis".
Also, it could be described as annual earnings paid out over a year.
Example: James gets paid $7/hr and works 4 hour days and 5 days a week. His weekly earnings would turn out to be $140.
Example #2: Jonquavius gets paid $15/hr and works 8 hours a day for 7 days a week. His weekly earnings would turn out to be $840.
Answer:
D, the observed frequency of landing heads up gets closer to the expected frequency based on the probability of the coin landing heads up.
Step-by-step explanation:
As of now, the observed frequency states that the coin will land on heads 4/12 times. The expected frequency states that the coin will land on heads 50% of the time, or 6/12 times. As the number of trials increases, the observed frequency will get closer to the expected frequency.
