Answer:
Ratio = 11:9
Boys = 440
Girls = 360
Explanation:
Given that, in a school,
Total number of students = 800
Also,
Percent of boys = 55%
Therefore, number of boys = 55% of 800
No. of boys = 55/100 x 800
No. of boys = 55 x 8 =
No. of boys = 440
Therefore, we will get,
No. of girls = (800-440)
No. of girls = 360
Therefore, we will get,
Ratio of boys to girls = 440/360
Ratio = (40*11)/(40x9)
Ratio = 11/9
Hence, the ratio of boys to girls is 11:9 and number of boys and girls is 440 and 360 respectively.
Answer:
x = -7, A = 65 degrees
Step-by-step explanation:
[It is important to know that in any triangle, the sum of all three angles is equal to 180 degrees]
Therefore,
x + 72 + x + 51 + 71 = 180
2x + 194 = 180 [collect like terms]
2x = -14 [subtract 194 from both sides]
x = -7 [divide both sides by 2]
To find A, we substitute the value of x into x + 72:
A = (-7) + 72
A = 65 degrees.

For each hour she works, her earning goes up $12.
When time(hours) = 1, The point's amount earned (y) is at $12.
When time(x) = 2, the point's amount earned (y) is at $24.
etc.
