Answer:
(b) 71%
Step-by-step explanation:
Put the given value of x in the formula and do the arithmetic.
-0.414(85) +106.55 = -35.19 +106.55 = 71.36
About 71% of the audience will finish watching the film.
The answer is 36, because when you divide 80/20 it is going to be 4 and 9*4 is 36!
Answer:
1385
Step-by-step explanation:
1) the difference is d=25-8=42-25=17;
the sequence given in the condition is arithmetic one (linear relationship).
2) in order to calculate the value of the 82d term:
a(n)=a(1)+d*(n-1), where n - number of required term (it is 82), then
a(82)=8+17*(82-1)=8+1377=1385.
Answer:
C. Add 15 to both sides
Step-by-step explanation:
Given equation:
99x – 15 = 45
To solve:
<u>Step 1</u>: Add 15 to both sides:
⇒ 99x – 15 + 15 = 45 + 15
⇒ 99x = 60
<u>Step 2</u>: Divide both sides by 99:
⇒ 99x ÷ 99 = 60 ÷ 99
⇒ x = 60/99
⇒ x = 20/33
To simplify the expression (5x^2 - 21x - 20) / (5x^2 - 16x - 16), we can check if there are terms that are needed to be added or subtracted. In this case, there are none. We just check the factors of each polynomial above and below. The factored equation of the numerator is (x-5)*(x + 4/5) while that below is (x-4)* (x + 4/5). In this case, we cancel <span>(x + 4/5). Hence the answer is (x-5) / (x-4)</span>
