Answer:
74.6018 Miles per hour
Step-by-step explanation:
Step 1: How many seconds are in an hour? There are 60 seconds in a minute and 60 minutes in an hour, so there are 60*60 = 3600 seconds in an hour.
Step 2: How many feet are in a mile? There are 5280 feet in a mile.
Step 3: To convert feet per second to miles per hour, first multiply by 3600, then divide by 5280. The fraction 3600/5280 reduces to 15/22.
To convert feet per second to miles per hour, multiply by 15/22.
So: 109.416 feet/second * (15/22) = 74.6018 miles/hour
Step-by-step explanation:
when multiplied together, the gradients of the 2 graphs should equal -1 (of they are perpendicular).
x-7y=4
-7y= -x + 4
y= -1/7 x + 4/7
21x+ 3y=11
3y=-21x+11
y=-21/3 x + 11/3
-21/3 * -1/7 = 1
when multipled together, the 2 gradients dont equal -1 therefore they are not perpendicular
unless I've made a mistake with the signs at some point haha
So the right answer is B 942 ft^2
Answer:
3.75
Step-by-step explanation:
1.5 equals 30 ft so x2 equals 60 then 15 is half of 20 so half of 1.5 in is .75 so 3 plus .75
option B
Cos theta is positive and sin theta is negative in quadrant IV
We have to find opposite side using Pythagorean theorem.
x² + 4² = 5²
x² + 16 = 25
x² = 25- 16
x² = 9
