The area of the floor of a cubical room is 49
[tex] {m}^{2} [/tex]
Find the area of 4 walls
Step-by-step explanation:
Since its a cube, Area of Floor = Area of Wall (Area of Square)
Area of 1 wall =
[tex]49 {m}^{2} [/tex]
Area of 4 walls =
[tex]49 \times 4 \\ = 196 {m}^{2} [/tex]
A cubical is a 3D square where all the sides are the same length.
The area of the floor is 49 square metered.
Since all sides are equal the area of the walls would also be 49 square meters each.
The area of the 4 walls would be 49 x 4 = 196 square meters.

Find the value of x
Answer:
x=80
Step-by-step explanation:
(x+30)=110 because they are vertically opposite angles.
x+30=110
x=110-30
x=80
Answer:
x = 80 degrees
Step-by-step explanation:
x + 30 = 110
- 30 = -30
x = 80 degrees

Match the following inequalities to the correct graph below.
9514 1404 393
Answer:
14. F -3.5 ≤ x
15. D x > -5
16. E -2 > x
Step-by-step explanation:
If the circle is open, the inequality will not include the "or equal to" case. That is, the symbol will be < or >. If the circle is a solid dot, then the symbol will be ≤ or ≥.
When shading is to the right, the variable values are greater than the limit. When shading is to the left, variable values are less than the limit.
___
14. The limit is -3.5, and the dot is solid. The expression will be ...
x ≥ -3.5 or -3.5 ≤ x . . . . . matches choice F
__
15. The limit is -5, and the dot is open. The expression will be ...
x > -5 or -5 < x . . . . . matches choice D
__
16. The limit is -2, and the dot is open. The expression will be ...
x < -2 or -2 > x . . . . . matches choice E

A construction crew is lengthening a road that originally measured 44 miles. The crew is adding 1 mile to the road each day. The length, L (in miles), after d days of construction is given by the following function.
L(d)= 44+d
What is the length of the road after 35 days?
Answer:
The length of the road after 35 days is of 79 miles.
Step-by-step explanation:
The length of the road, after d days, is given by:
[tex]L(d) = 44 + d[/tex]
What is the length of the road after 35 days?
This is l when d = 35. So
[tex]L(35) = 44 + 35 = 79[/tex]
The length of the road after 35 days is of 79 miles.
Find the midpoint of the segment with the following endpoint (9,2) and (5,5)
Answer:
(7, 3.5)
Step-by-step explanation:
find the distances between the x and y
9 and 5 are 4 apart, and 2 and 5 are 3 apart
divide those distances by 2
4/2 = 2, 3/2 = 1.5
add those distances to the smaller of the x and y
5 + 2 = 7, 2 + 1.5 = 3.5
those two numbers are the midpoint (7, 3.5)

Which of the following numbers would be to
the left of the number -1 on a number line?
8
4
0
-0.5
-4
Answer:
-4
Step-by-step explanation:
Numbers decrease on a number line as you go left. So, to find a number to the left of -1, you need to find a number that is smaller. Since negative numbers decrease in value as they get further from 0, -4 must be smaller than -1. All other values listed will be to the right of -1.
