Answer: 450 cm squared if not including the inside surface
900 cm squared if including the inside suface
Step-by-step explanation:
A=2(wl+hl+hw)
A=2(150+90+60)
A=2(300)
A=600
but we have a lidless box so we need to subtract the lid...
600-(wl)=
600-(150)=450
If we are including the inside surface it would double as we would be covering both exposed surfaces of bottom, 2 ends, and 2 sides....
450x2=900
The surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.
What is surface area?The space occupied by any two-dimensional figure in a plane is called the area. The area of the outer surface of any body is called the surface area.
(i) The surface area will be calculated as,
A=2(wl+hl+hw)
A=2(150+90+60)
A=2(300)
A=600
But we have a lidless box so we need to subtract the lid.
600-(wl)=
600-(150)=450
(ii) If we are including the inside surface it would double as we would be covering both exposed surfaces of the bottom, 2 ends, and 2 sides.
450x2=900
Therefore, the surface area is 450 cm squared if not including the inside surface and 900 cm squared if including the inside surface.

What is the steps to solve -4(5+x)=39
Answer:
x = -14.75
Step-by-step explanation:
-4(5+x)=39 (Distribute)
-20 - 4x = 39 (Add 20 on both sides)
-4x = 39 + 20
-4x = 59 (Divide by -4)
x = -14.75
Answer:
First think of what you are trying to solve.
What is X?
Reverse the steps in solving:
[tex]39 / -4 = -9.75[/tex]
Now after doing that, subtract it by 5:
[tex]-9.75 - 5 = -14.75[/tex]
Now after doing that, to check your work:
[tex]-14.75 + 5 = -9.75 * -4 = 39[/tex]
So the answer for X is -14.75
There you go I hoped I helped :]

If the length of the radius and the height of a right circular cylinder are both tripled to form a larger cylinder, what is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? (Note: The two cylinders are said to be "similar.")
Answer:
The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27:1
Step By Step Explanation:
Volume of the smaller cylinder(V1)=π(r^2)h
Volume of the larger cylinder(V2)=π(r^2)h
=π(3r)^2*3h
=π*9(r^2)*3h
=27π(r^2)h
The ratio of the volume of the larger cylinder to the volume of the smaller cylinder is 27π(r^2)h/π(r^2)h i.e. 27:1
find the volume of the cylinder
Answer:
V≈56.55
Step-by-step explanation:
V=πr2h=π·32·2≈56.54867

Answer:
not on the same line
Step-by-step explanation:
Any two distinct points define a line. Additional points may or may not be on that line. If they are on the line, they are collinear with other points on the same line.
Any point not on the line is noncollinear with the points that are on the line.

Answer:
P₂ and x are both supplementary to N₁Q₁R = 90° -xΔSMP ≅ ΔSMR ∴ PS ≅ SRStep-by-step explanation:
1. Angles P₂ and N₁ are opposite angles of inscribed quadrilateral PMNQ, so are supplementary. Angles N₁ and N₂ form a linear pair, so are supplementary. Angles supplementary to the same angle (N₁) are congruent, hence P₂ = x ≅ N₂
__
2. ΔPMQ is isosceles, so angle Q₁ is also congruent to x.
__
3. In ΔPMQ, the sum of angles is 180°, so ...
M₁ +2x = 180°
Dividing by 2 gives ...
M₁/2 +x = 90°
Angle M₁ subtends arc PQ of circle M. Angle R inscribed in circle M subtends the same arc, so ...
R = (M₁/2)
R = 90° -x
__
4. From the above, we know that angles N₂ and R are complementary (total 90°), so angle S₂ = 90°. Segment MS will only intersect chord PR at right angles at the midpoint of that chord.
Hence S is the midpoint of PR and PS = SR.

On a coordinate plane, parallelogram H I J K is shown. Point H is at (negative 2, 2), point I is at (4, 3), point J is at (4, negative 2), and point K is at (negative 2, negative 3).
HIJK is a parallelogram because the midpoint of both diagonals is __________, which means the diagonals bisect each other.
(1,−1)
(1,1)
(1,0)
(0,1)
Answer:
(1,0)
Step-by-step explanation:
Given
[tex]H = (-2,2)[/tex]
[tex]I = (4,3)[/tex]
[tex]J = (4,-2)[/tex]
[tex]K = (-2,-3)[/tex]
Required
The midpoint of the diagonals
Midpoint is calculated as:
[tex]M = (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]
For H and J, the midpoint is:
[tex]M = (\frac{-2+4}{2},\frac{2-2}{2})[/tex]
[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]
[tex]M = (1,0)[/tex]
For I and K, the midpoint is:
[tex]M = (\frac{4 - 2}{2},\frac{3-3}{2})[/tex]
[tex]M = (\frac{2}{2},\frac{0}{2})[/tex]
[tex]M = (1,0)[/tex]
The midpoint of both diagonal is: (1,0)

an experiment compares the heights of two plants over time. a plant was 2 cm tall at the beginning of the experiment and grew 0.5 centimeters each day. the function f(t)=0.5t+2 represents the height of the plant in centimeters after t days.
The graph shows the height of the second plant, g(t) in centimeters, as a function of time t in days.
Part 1: which plant, f or g, was growing faster?
Part 2: Which plant, f or g, was taller to begin with?
Part 3: Which plant, f or g, was taller after 8 days?
Answer:
Part 1: plant f
Part 2: plant g
Part 3: plant g
Step-by-step explanation:
✔️First plant:
Function: f(t) = 0.5t + 2
where,
f(t) = height of plant
t = number of days
m = slope/rate of change = 0.5 cm/day
b = y-intercept/initial height = 2 cm
✔️Second Plant: using two points on the graph, (0, 5) and (16, 9), let's find b and m for the function of the second plant.
Slope/rate of change (m) = ∆y/∆x = (9 - 5)/(16 - 0) = 4/16 = 0.25
m = 0.25 cm/day
The y-intercept or initial height is the y-coordinate of the point where the line intercepts the y-axis = 5
b = 5 cm
Towbrute the equation of the function, substitute m = 0.25 and b = 5 into g(t) = mt + b
Thus:
g(t) = 0.25t + 5
Knowing these, let's answer the problem given:
Part 1: plant f was growing faster because it has a greater rate of change/slope (m) of 0.5 cm/day
Part 2: plant g was taller because it has a greater initial value/y-intercept (b) which is 5 cm
Part 3: To find out which plant was taller after 8 days, substitute t = 8 into the equation of each function:
Plant f: f(t) = 0.5t + 2
f(8) = 0.5*8 + 2 = 4 + 2
f(8) = 6 cm
Plant g: f(t) = 0.25t + 5
g(8) = 0.25*8 + 5 = 2 + 5
g(8) = 7 cm
Thus, plant g was taller after 8 days having 7 cm
