7) The height of a box is represented by the expression
(x.- 2) centimeters. The volume of the same box is
represented by the expression (x3 - 8 ) cubic centimeters.
Which expression below represents the area of the base of the
box?
A. x2 – 2x + 4
B. x2 + 2x + 4
C. X? + 6x - 4
D. x2 - 6x + 4
Given:
Height of box = (x-2)
Volume of box = [tex](x^3-8)[/tex]
To find:
The expression for the base area.
Solution:
We know that,
Volume of a box(V) = Base area(B) × Height(h)
[tex]V=Bh[/tex]
[tex]\dfrac{V}{h}=B[/tex]
On substituting the given values, we get
[tex]B=\dfrac{x^3-8}{x-2}[/tex]
[tex]B=\dfrac{x^3-2^3}{x-2}[/tex]
[tex]B=\dfrac{(x-2)(x^2+2x+2^2)}{x-2}[/tex] [tex][\because a^3-b^3=(a-b)(a^2+ab+b^2)][/tex]
[tex]B=x^2+2x+4[/tex]
So, the base area is [tex]x^2+2x+4[/tex].
Therefore, the correct option is B.
Find the value of X while a⊥B and b║c
Ratio number 1.50:1.38
Does anyone know know the correct answer?! Please help! If the answer is correct ill mark you as the best!
Answer:
D)
Step-by-step explanation:
In slope-intercept form in order to find the perpendicular equation you change the sign and find its reciprocal.
So in the equation y= -3x+1, the opposite sign of - is + and the opposite of 3 is 1/3

Determine whether the lines with the given slopes are parallel, perpendicular, or neither.
m1= 1/2 & m2= 0.5
Answer:
The given lines are parallel.
we already know that for parallel condition we apply;
m1=m2
1/2=0.5
0.5=0.5

Given: AABC with vertices A(5, -2), B(5, -7), and C(1, -2). Which set of
coordinates best repositions the triangle to make a coordinate proof easier?
Answer:(0,0),(0,4) and (5,0)
Step-by-step explanation:
It is easy to find lengths of horizontal and vertical segments and distances from (0,0) so always place one vertex at the origin and one or more sides on an axis.
So this answer has a y intercept and an x intercept.

The product of a number and negative three is twenty-seven. Which of the following could represent this statement?
-3n + 27
-3(27) = n
-3n = 27
-3 = 27n
Answer:
-3n=27
Step-by-step explanation:
The value of n is -9.
So we can represent this in an equation. We won't get that as a result if we multiply the following
-3n=27 Divide -3 by both sides.
n=-9
Answer:
The product of a number and negative three is twenty-seven.
-3n=27
How to solve y=2x-10 and 6x+7y=10 using substitution
Answer:
x=4
Step-by-step explanation:
y=2x-10 and 6x+7y=10
6x+7(2x-10)=10
6x+14x-70=10
20x=80

Which table represents a linear function that has a greater unit rate than that of the function y = 200x + 50?
Answer:
D
Step-by-step explanation:
A unit rate is basically which one increases more as time goes on. Now. to make it easier let me explain visual.
You have 50 apples at the start and every hour you get 200 more apples, sweet!
Now let's look at the chart.
The first one is 200x+100, this is wrong since this has a better start but you don't get as much apples.
Same goes for the B and C. The only one that would make sense is D since you're also adding 10 more apples for each one you increase.

The cheerleaders at City High make their own
megaphones by cutting off the small end of a
cone made from heavy paper. If the small end of
the megaphone is to have a radius of 2.5 cm,
what should be the height of the cone that is cut
off?
2.5 cm
60 cm
Answer:
The height of the cone that is cut would be 2.5
A train traveled at 62 miles per hour for 7.5 hours. How far did the train travel in 7.5 hours? Use the formula D = r x t
d=distance
r=rate
t=time
Answer:
465 miles
Step-by-step explanation:
D = r * t
D = 62 * 7.5 = 465 miles
Answer:
465
Step-by-step explanation:
We know that the rate is 62 mph. The time is 7.5 h.
Plug it into the existing equation:
D = r × t becomes D = 62 × 7.5
Just stick that into a calculator to get 465.
The number of girls in a classroom is greater than the number of boys. There are more than 2 girls. Write a system of inequalities to model this situation. Use x to represent the number of boys and y to represent the number of girls.
Answer:
x < y > 2
Step-by-step explanation:
Girls is more than boys, so:
y > x
Girls is more than 2, so:
y > 2
So:
x < y > 2

Given the equation x^2=16, which statement below describes the solution(s)?
Answer:
4
Step-by-step explanation:
x²=16
x=√16
x=4
Answer:
x^2=16
^ stands for power or exponent
so, the equation is: x square= 16
for this x should be equal to 4
now,
4^2=16

find the area of the regular hexagon PQRSTU of sides 8 cm as shown in the figure
Answer:
Area = 245m^2
Step-by-step explanation:
We can split this figure into 2 parts, a rectangle and a trapezoid.
Rectangle Sides = 10m and 20m
Area = 10m x 20m = 200m
Trapezoid formula = a+b/2(h)
a and b are the 2 bases and h is the height
Using a little deductive reasoning we get the following, 5+10/2(6)
This simplifies to 15/2(6) -->
7.5(6) = 45
Thus, our area is 200 + 45, or 245m^2
