You can set up an equation.
Let x = measure of the length.
Width: 2/3x
Length: x
From the question, we know that the perimeter is 70 and based on our prior knowledge, we know that for a rectangle, the perimeter is equal to 2 times the length added to two times the width.
2(2/3x + x) = 70
4/3x + 2x = 70
10/3x = 70
x = 21
So the length is 21 meters.
And since the width is 2/3 the length, 2/3 x 21 is 14.
So the width is 14 meters.
And if you add 21 + 21 + 14 + 14, it will equal 70 meters.
Now let's find the area.
21 x 14 = 294 square meters.
Answer:
42 tens is the same as 420 ones
Step-by-step explanation:
42 tens = 42 times 10 = 420 ones
10 men can survive for 24 days with 15 cans of ration
so , 1 man can survive for 1 day with 15/(10*24) cans of ration
so, 8 men can survive for 36 days with (15*8*36)/240 = 18 cans of raion
Answer: a = -5
Heyy, so with this question you would have to substiute 1 for x because normally the coordinates have x first then y. E.g. (x,y)
soo, f(1) = a(1)^2 +5
then, f(1) = a + 5
then equate to zero. E.g. a+5=0
then move over 5 to other side E.g. a=-5
soo.. yah.. pretty sure haha :)
Answer:
4/9
Step-by-step explanation:
4 plus 3 plus 2 = 9 total amount of scraps, goes on the denominator.
there are 4 orange scraps which is your numerator.
so it is 4/9 or a 44% chance/probability in getting an orange scrap.
