Answer:
B, 20mph
Step-by-step explanation:
540 miles in 27 hours is 540/27 = 20 miles in 1 hour. This is 20 mph
H = 2sqrt2
D = 6sqrt3
In a 45,45,90 triangle the hypotenuse is (x)sqrt2 while the side lengths are equivalent being a single value x. Therefore, when given the hypotenuse and solving for the leg, divide 4 by sqrt2 to get 4sqrt2/2 which simplifies to 2sqrt2 when the denominator and numerator cancel.
In a 30,60,90 triangle the short leg x is across from the 30 degree angle meaning the angle across from the 60 degree angle is x times the sqrt of 3. Therefore the long leg is 6sqrt3
Answer:
36 boys
Step-by-step explanation:
3
Please write the ratio as 3:5 or as --------
5
Note that 3 + 5 = 8, so that the fraction of boys in the club is 3/8 and that of girls is 5/8.
How many are in the club altogether? Let this count be represented by c. Then (5/8)c = 60.
Multiplying both sides of this equation by (8/5), to isolate c, we get:
c = (8/5)(60) = 96. Thus, there are 96 Science students altogether.
3/8 of this number are boys. This comes out to (3/8)(96) = 36 boys.
We could also solve this problem in the following manner:
3 b
------ = ------- , where b represents the number of boys.
5 60
Then 5b = 180. Dividing both sides by 5, we get b = 180/5 = 36 boys
Answer:
well 34/2= 17 so the kids in Bing-BU ate more total bananas
Step-by-step explanation:
Both the angles will be 105°
Just add up the given angles, subtract the result by 360, and divide by 2.
