Answer:
Step-by-step explanation:1.
Use law of cosine.
AB^2 = AC^2 + BC^2 - 2 * AC * BC * cos(angle ACB)
AB^2 = 53^2 + 71^2 - 2(53)(71)cos(53)
Using calculator,
AB = about 57.6259 feet
2.
Law of cosine again.
d^2 = 400^2 + 90^2 - 2(400)(90)cos(45)
using calculator,
d = about 342.3278 feet
Answer:
133 windows
Step-by-step explanation:
It is given that,
A window washer cleaned 38 windows in 2 hours.
We need to find how many windows did he clean in 7 hours.
2 hours = 38 windows
1 hour = 19 windows
For 7 hours, multiply 19 and 7.
7 hours = 19 × 7 windows
= 133 windows
Hence, in 7 hours he can clean 133 window
Answer:
19
Step-by-step explanation:
The vertical axis of a histogram indicates the total amount of people that meet the weights indicated in the x-axis in the analysed population. From data we can construct the following table:
x-axis y-axis
115 1
135 4
155 3
175 1
195 5
215 2
235 3
So there are: 1+4+3+1+5+2+3 = 19 team members included in the histogram.
