Answer:
[tex] \displaystyle A_{ \text{surface}} = 42cm ^{2} [/tex]
Step-by-step explanation:
we are given the base area of a cube
recall the surface area formula of a cube
[tex] \displaystyle A_{ \text{surface}} = 6( {a}^{2} )[/tex]
notice that, we are given the base area 7cm² in other words we are given a² i.e 7cm²
Thus substitute:
[tex] \displaystyle A_{ \text{surface}} = 6( 7 )cm ^{2} [/tex]
simplify multiplication:
[tex] \displaystyle A_{ \text{surface}} = 42cm ^{2} [/tex]
and we are done!

Answer:
x = √149
Step-by-step explanation:
Compartmentalize the odd figure into a rectangle (with sides 3 and 7) and a triangle (with sides 10 and x). Now, that you have a triangle, you can use the rectangle underneath to find the bottom side of the triangle--it is 7. The triangle that has been formed is a right triangle, so we can use the Pythagorean Theorem to find x, which is the hypotenuse.
10² + 7² = x²
100 + 49 = x²
149 = x²
√149 = x
Answer:
7√2
Step-by-step explanation:
Remark
Draw another line parallel to 7.
Move to the other end of 3
that makes the vertical leg on the left 10 - 3 = 7
You now have a smaller right triangle.
Equation
a = 7
b = 7
c = x
Solution
x^2 = 7^2 + 7^2
x^2 = 49 + 49
x^2 = 98
x^2 = 7 * 7 *2
sqrt(x^2) = sqrt(7 * 7 * 2)
The rule about square roots is for every pair of factors you can take one out of the square root sign and throw the other one away.

Answers
Answer:
1 ÷ 2(9 + x)
4.5 + 0.5x
Step-by-step explanation:
Given that
We write the expression i.e. half of the sum of $9 and a number
Here we need to write the two expression that is different from each other
So,
Let us assume the number be x.
Now The first equation depend on the information given will be:
= 1 ÷ 2(9 + x)
And, The second equation is
= (9 + x) ÷ 2
= 4.5 + 0.5x

The answer would be 1/6 IF you took 1/6 of the full sheet of paper, but if you are taking 1/6th of half of the paper, then you are taking half the amount. Basically, you would need two 1/6 pieces of one half to be equivalent to one 1/6th piece on the full sheet.

The box plots show the data distributions for the number of customers who used a coupon each hour during a two-day sale.
Which measure of variability can be compared using the box plots?
interquartile range
standard deviation
mean
median
Answers
Answer:
Interquartile age
Step-by-step explanation:
The box plots that is being referred to are missing, however, we can still answer this without the box plots.
The appropriate measure of variability that can be easily determined by a box plot is the interquartile range. Which is the difference between the 3rd quartile and the 1st quartile.
On a box plot, the first quartile is the data value ta the beginning of the edge of the rectangular box while the third quartile is at the end of the edge of the rectangle box. So, this makes is easy for use interquartile range as a measure of variability when comparing both.
Answer:
Interquartile range (IQR)
explanation:
Mean and median are both measures of center so it can't be those two, and the standard deviation is a measure of variability but only when the graph, box plot or any other type of graph is symmetric
