The formula for the surface area of a cube is:
______________________________________________________
→ A = 6a² ;
______________________________________________________ → in which:
______________________________________________________
A = surface area of the cube— for which we shall solve ;
(in "square units" ; or, " in² " ; in our case) ;
a = side length = " 8 in " (given);
→ Note: A cube has all equal side lengths.
→ The "6" in the formula accounts for "6 sides" of a cube.
_______________________________________________________
→ To solve for the surface area of the cube; plug in our known value(s);
& solve; as follows:
_______________________________________________________
→ A = 6 a² ;
= 6 * (8 in)² ;
= 6 * 8² * in² ;
= 6 * 8 * 8 * in² ;
= 48 * 8 * in² ;
= 384 in² ;

Kara and Steven are biking around a 1,800 kilometer path. They start biking from the same place, at the same time, and in the same direction. Kara bikes at a speed of 15 km/h and Steven bikes at a speed of 30 km/h. How long will it take before Steven and Kara will be at the same place of the path next time?
Answers
Time taken before the cyclist are on the same sport will be found as follows:
time=distance/(relative speed)
distance=1800 km
given that the cyclist will be riding towards the same side, then
relative speed=(Steve's speed-Kara's speed)=30-15=15 km/h
thus time taken will be:
time=1800/15
=120 hours

Answers
Answer:
Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).
Step-by-step explanation:
Given Vertices of Rectangle are ( 5 , -3 ) , ( 5 , -8 ) , ( 8 , -3 )
To find: Coordinate of Fourth Vertex of the rectangle.
First, Plot all given three points on the graph.
Graph is attached.
We know that Opposite sides of the rectangle are equal and parallel.
Also All angles of rectangles are right angle.
So to satisfy these properties of rectangle.
4th coordinate must be on line x = 8 and y = -8.
⇒ Fourth coordinate = ( 8 , -8 )
Therefore, Coordinate of 4th vertex of the rectangle is ( 8 , -8 ).

Answer : The numbers are 21 and 28.
Hope this helps. - M
The problem is solved using a system of equations to find that the two numbers in question are 21 and 28.
To solve the problem involving two numbers where the sum equals 49 and the sum of the larger number and twice the smaller number equals 70, we need to form a system of linear equations and solve for the unknowns. Let's denote the smaller number as s and the larger number as l.
The sum of the two numbers is 49: s + l = 49.The sum of twice the smaller number and the larger number is 70: 2s + l = 70.Subtract the first equation from the second to find the value of s.
2s + l - (s + l) = 70 - 49
Which simplifies to:
s = 21
Substitute the value of s into the first equation:
21 + l = 49
And solve for l:
l = 28
Therefore, the smaller number is 21 and the larger number is 28.
Solve the inequality and describe the solution set:

Answers
You want to get the y only on one side of the equation. To get rid of the -6 you have to add 6 to both sides to even out the equation.
y-6≥12
+6 +6
y ≥18
Answer: The solution set is y≥18.
Step-by-step explanation:
Since we have given that
[tex]y-6\geq 12[/tex]
We need to first find the inequality and find the solution set.
[tex]y-6\geq 12\\\\y\geq 12+6\\\\y\geq 18[/tex]
So, the solution set for this would be all the values of y which is greater than 18.
i.e. y≥18.
