Answer:
b = 252 in
Step-by-step explanation:
cos theta = adjacent side over hypotenuse
cos 38 = b/ 320
Multiply each side by 320
320 cos 38= b/320 * 320
320 cos 38 = b
252.1634412 =b
To the nearest whole number
252 =b
First, let's find the number of lunches:
14*3 = 42
To find how many lunches have ham sandwiches, we multiply the total number of sandwiches by the percentage of the ham sandwiches:
0.55 * 42
Multiply:
23.1
We can round down:
There are about 23 lunches with ham sandwiches
Answer:
49.132 m²
Step-by-step explanation:
Area of a triangle=1/2(base×height)
Area=1/2(6×8)
Area=24 m²
Now
Area of semi circle=πr²/2
Area=(3.14)(8÷2)²/2
Area=(3.14)(4)²/2
Area=(3.14)(16)/2
Area=50.265/2
Area=25.132 m²
Now
Total area=area of triangle+semi-circle
Total area=24+25.132
Total area=49.132 m²
