Answer:
B, D
Step-by-step explanation:
-3(0.15 - 0.2 +0.25p) = -3(-0.05 +0.25p) = 0.15-0.75p
A doesn't work because -3(0.15 - 0.2 +0.25p) = -0.45+0.6-0.75
C doesn't work because 3(0.15+0.2+0.25p) = 0.45+0.6+0.75 which doesn't equal -0.45+0.6-0.75.
E doesn't work because 0.15-0.2 = -0.05 not 0.05.
There were 16 total storms, meaning our denominator is 16. Since 8 grew into hurricanes, we can leave that alone. Since 5 out of 16 storms were major, 5 is our numerator.
5/16 storms were major because 8 were hurricanes and the other 3 were other kinds of storms. As a decimal conversion, about 31% of these storms were major.
How to find the percentage conversion:
Step 1: We take the fraction 5/16.
Step 2: Since our numerator is 5 and the default denominator is a maximum of 100, we can multiply 5 by 100.
5 x 100 = 500
Step 3: We can divide 100 by 16 to get our decimal conversion.
100 divided by 16 will give us 31.25, which also is representative of 31 and 1/4 added together.
Your final answer: With there being 16 storms, 5 of these storms are major (5/16). In terms of if there were 100 total storms, about 3/10 of these storms were major.
Answer:
Length is 20 meters and Width is 16 meters
Step-by-step explanation:
A parallelogram is a 4-sided figure with 2 pair of parallel sides.
The perimeter is the sum of all 4 sides of the parallelogram.
Let the length of parallelogram be x and width be y.
The perimeter is 72, thus we can write:
x + x + y + y = 72
or
2x + 2y = 72
Also, width is 4 less than length, thus we can write:
y = x - 4
Now, we replace the 1st equation with the 2nd equation and solve for x first. Shown below:
2x + 2y = 72
2x + 2(x - 4) = 72
2x + 2x - 8 = 72
4x = 72 + 8
4x = 80
x = 80/4 = 20
And now y:
y = x - 4
y = 20 - 4
y = 16
Thus, the Length is 20 meters and Width is 16 meters
Answer:
A: 39.1304348% OR 39%
B: 33.3%
Step-by-step explanation:
Part A:
find the total amount of children: 90+20+80+40=230
90-20=50
i got this from taking away the amount that like watching tv and not reading so from this you know 50 of those 90 that like watching tv also like tv and reading.
80-40=40
(same explanation as 90-20=50)
then do 50 +40 which equals 90
now you need to turn it into a percentage.
90/230=
9/23
=39.1304348%
if you need round it, do so!
Part b:
40+20=60
20/60= 2/6
=1/3
=33.3%
