A) x/y = 2/3
B) x + y = 105
Solving Equation A for y
A) y = 1.5x
Substituting A into B
B) x + 1.5x = 105
2.5x = 105
x = 42
y = 63
60 min = 1 hr
30 times 2 = 60 minutes
7.7 times 2 = 15.4 km
15.4 km per hr is the answer
PLEASE MARK BRAINLIEST
Use Pythagoras theorem. (a^2 + b^2 = c^2)
300^2+300^2 = 180000
√180000 = 424.3
The answer is 424 foot.
Hope this helps.
Answer:

Step-by-step explanation:
we are given a trapezoid
we want to figure out the area
remember that,

where a and b represent the parallel lines and h represents the height
we get from the pic that a and b are 5 and 15 respectively and h is 7
so substitute:

simplify addition:

simplify division:

simplify multiplication:

since we multiply two same units we of course have to use square unit
hence,

821 divid 2 equals 410 but your not saying how many portions it is equal to
