Answer:
15
Step-by-step explanation:
Let x represent the number of hours it takes the larger hose to fill the pool. Then each hour, it contributes 1/x of the pool volume. Similarly, the other hose contributes a volume of 1/(1.5x) each hour.
The two hoses together contribute a volume of 1/9 of the pool volume each hour:
1/x +1/(1.5x) = 1/9
2.5/(1.5x) = 1/9 . . . . combine the fractions
22.5/1.5 = x . . . . . . multiply by 9x
15 = x
It takes the larger hose 15 hours to fill the pool alone.
Answer:
Bottom left graph
Step-by-step explanation:
The outlier will always be the number apart or greater than all of the other numbers in the graph
hence, the answer is the bottom left graph
D is the correct answer to this question.
The rules for converting fractions with denominators 10, 100, 1000, etc. into decimal fraction:
(i) Count the number of zeroes coming after 1 in the denominator.
(ii) Count an equal number of places in the numerator starting from the unit digit then place the decimal point to the left of the digit reached.
Let us consider some of the following examples;
1. Convert 819/100 to decimal.
Given, 819/100 This explanation will help you
To answer this problem, we can find to determine angle A first by taking the arc sin of 0.83. Angle A is equal to 33.9. Hence angle B should be 90-33.9 equal to 56.10. sin of 33.9 added to the sin of 56.10 is equal to 1.38. or we can just directly add the cos values since the sin is just the same as the complementary of each
