Answer:
122.67 or round it to 123
Step-by-step explanation:
i used the butterfly method.
92/75 = x/100.
i multiplied 92*100=9200
then i divided it with 75.
9200/75=x
so the answer is
x=122 or 123
Answer:
True; quadrants I & IV
Step-by-step explanation:
We know the relation between sine and cosine function which is given by
Let us solve this equation for cosine function.
Take square root both sides. When ever we take square root we need to write the solution in plus minus form
If Θ is in quadrants I and IV then the value will be positive and if Θ is in II and III quadrant then the value is negative.
Hence, if Θ is in quadrants I & IV, then we have
Thus, the correct option is: True; quadrants I & IV
Answer:
Step-by-step explanation:
This is a geometric sequence; we know that because of the words "common ratio." The general formula for a geometric sequence is
a(n) = a(1)*r^(n - 1), where r is the common ratio.
Here, a(1) = 1, r = 1/3, and so
a(1) = 1 (given)
a(2) = 1/3 (this is a(1) multiplied by 1/3)
a(3) = 1/9 (this is a(2) multiplied by 1/3)
a(4) = 1/27
a(5) = 1/81
Answer:
Jack can paint a certain room in 3 hours, lisa is 4 hours, and sue in 2 hours. ... Jack's rate is one-third of a job per hour, Lisa's is one-fourth of a job per hour and Sue's is one-half of a job per hour. If they all work together for t hours, one whole job is completed. t/3 + t/4 + t/2 = 1 .
Step-by-step explanation:
Answer: 50%
Step-by-step explanation:
From the question, we're given the information that Waipio Rd in Honokaa, Hawaii, is one of the steepest roads in the world and that it rises 450 ft over a horizontal distance of 1,000 ft.
Therefore, the percentage grade of this hill will be calculated as the height over the length and this will be:
= 450/1000 × 100
= 45%
= 0.45
= 0.5 to nearest tenth
= 50% to nearest tenth.
