Answer:
a(75) = 793
Step-by-step explanation:
Arithmetic Explicit Formula: an = a1 + (n-1)d
Step 1: Find equation
d = (1-(-10)) = 11
a1 = -21
an = -21 + 11(n-1)
Step 2: Plug in 75 as <em>n</em>
a(75) = -21 + 11(75-1)
a(75) = 793
And we have our final answer!

Answer: OPTION A.
Step-by-step explanation:
We know that a circle measures 360 degrees. Then, to determine the size of a section, we need to multiply the percent of the category by 360 degrees.
First, we need to write 65 out of a hundred in decimal form:
Now, let be "x" the degrees of the section representing 65 out of a hundred. We need to multiply 360 degrees by 0.65. Therefore, we get this result:
This matches with the option A.
Answer:
Federico
Step-by-step explanation:
11/10 is a mixed number, that means it is larger than the whole, which in this case is the money for the school trip, since the numerator is larger than the denominator, and Luis and Marisa both have numerators smaller than the denominator, that makes 11/10 the largest.
Since there is a 40% discount, this means that they subtracted 40% of the original price from the original price, meaning that $36 is 60% of the original price. We can use ratios to figure out the original price (so 100% of the price).
100% x
60% 36
x = 36*100 / 60 = 3600 / 60 = 360 / 6 = 60
We can check this quickly: 60 * 0.4 (or 40%) is 24. If we subtract 60-24 we get 36, so we did the problem correctly
