Answer:
77.78 mph
Step-by-step explanation:
[1] So we know that someone is driving 350 miles and it takes / took them 4 1/2 hours. I am going to change 4 1/2 to 4.5 for the sake of making it easier.
[2] Miles per hour, is, as it says, miles per hour. Aka, 
(your time is almost always on the bottom / the y)
[3] So, that being said, to solve you will but 350 over 4.5 like this: 
which calcuates to arounddd 77.78!
(I hope this is correct, I was slightly confused by the wording. Have a nice day!)
Step-by-step explanation:
<h2 /><h2>
AREA OF TRIANGLE </h2>
= 1/2× BASE× HEIGHT
= 1/2×25×50 yd²
= 625 yd²
We first write the word in math as x+3/5 = 5/7. Now we cross multiply our fractions and rewrite them with the LCD of 5 and 7. Our equation now looks like x + 21/35 = 25/35. We simplify our equation by subtracting 21/35 from both sides to get x = 4/35. 4/35 is already in lowest terms so it is our answer.
Answer:
50 degrees
Step-by-step explanation:
The 40⁰ angle is bisecting a right, or 90⁰ angle. The total of angles f and 40⁰ = 90⁰
f + 40⁰ = 90⁰
f = 50⁰
It's 77.7777777777777777%, but you can either round it to 77.77% or simply 78%
