Given:
Box A has a surface area of 98 in².
Box B is 4 times the size of box A.
To find:
The surface area of box B.
Solution:
Let "a" be the side of box A , then "4a" be the side of box B because box B is 4 times the size of box A.
We know that the areas of similar figures are proportional to the square of their corresponding sides.
Using cross multiplication, we get
Therefore, the surface area of box B is 1568 in².

Answer:
50=2(10+w)
Step-by-step explanation:
We know that perimeter is equal to the sides of a shape
A rectangle has two of the same length and two of the same width
P=2l+2w
We know the perimeter and length so plug that in and solve for w
50=2(10)+2w
50=2(10+w) - That matches answer choice D
30=2w
w=15
N + d + q = 35
0.05n + 0.10d + 0.25q = 6
n = d + 5
n + d + q = 35
0.05n + 0.10d + 0.25q = 6.....multiply by -4
----------------
n + d + q = 35
-0.20n - 0.40d - q = - 24 (result of multiplying by -4)
----------------add
0.80n + 0.60d = 11
0.80(d + 5) + 0.60d = 11
0.80d + 4 + 0.60d = 11
1.40d = 11 - 4
1.40d = 7
d = 7 / 1.40
d = 5 <==== there are 5 dimes
n = d + 5
n = 5 + 5
n = 10 <==== there are 10 nickels
n + d + q = 35
10 + 5 + q = 35
15 + q = 35
q = 35 - 15
q = 20 <=== there are 20 quarters
In the following sets; set A has a median of 10 and a mean of 8.85 and a skewness of -0.3061. Therefore about set A, the median of set A is larger than the mean of set A, It is also skewed to the left since it has a negative skewness and hence not symmetrical (skewness is 0).
set B, the median is 8 and the mean is 8 and the skewness is zero. therefore; set B has the same median and mean, set B is symmetrical since it has a skewness of 0. It is not right skewed (positive skewness)
