Step-by-step explanation:
4.
Surface area of a rectangular prism form : A=2(wl+hl+hw)
Substitute in values from the question: 558=2[(9)(11)+h(11)+h(9)]
Multiply where applicable: 558=2[(99)+11h+9h]
Combine like terms: 558=2[(99)+20h]
Divide both sides by 2: 279=(99)+20h
*note- This step can also be seen as multiplying the right side by 2 without messing with the left at all (558=(198)+40h) then you would solve in the same fashion as I will from here just with the alternative numbering*
Subtract to isolate the h: 180=20h
Divide both sides to isolate the h: 9=h
Now we see that the missing dimension h=9in
*note- I did not bold the equations with squares so please don't be confused by that*
5.
Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]
Substitute in values from the question: A=2π(3)(5)+2π[tex]3^{2}[/tex]
Multiply were applicable: A≈94.2+56.5
Add remaining values: A≈150.8
Now we see that the total surface area is 150.8[tex]m^{2}[/tex]
*note- whenever we solve for volume or SA of a figure we square the unit ([tex]m[/tex]➞[tex]m^{2}[/tex])*
6.
Surface area of a cylinder form: A=2πrh+2π[tex]r^{2}[/tex]
Substitute in values from the question: A=2π(6)(2)+2π[tex]6^{2}[/tex]
*note- we use 6 instead of the given value 12 because the equation calls for the radius and not the diameter*
Multiply were applicable: A≈75.2+226.2
Add remaining values: A≈301.6
Now we see that the total surface area is 301.6[tex]in^{2}[/tex]
*note- whenever we solve for volume or SA of a figure we square the unit ([tex]in[/tex]➞[tex]in^{2}[/tex])*
Hope this helps :)

A bridge is supported by triangular braces. If the sides of each brace have lengths 63 feet, 46 feet, and 40 feet, find the measure of the angle opposite the 46 foot side. Round to the nearest degree.
Answers
Given:
The sides of each brace have lengths 63 feet, 46 feet, and 40 feet.
To find:
The measure of the angle opposite the 46 foot side.
Solution:
According to the Law of Cosines:
[tex]\cos A=\dfrac{b^2+c^2-a^2}{2bc}[/tex]
We need to find the measure of the angle opposite the 46 foot side. So, [tex]a=46[/tex] and the other sides are [tex]b=63,c=40[/tex].
[tex]\cos A=\dfrac{(63)^2+(40)^2-(46)^2}{2(63)(40)}[/tex]
[tex]\cos A=\dfrac{3969 +1600-2116}{5040}[/tex]
[tex]\cos A=\dfrac{3453}{5040}[/tex]
[tex]\cos A=\dfrac{1151}{1680}[/tex]
Taking cos inverse on both sides, we get
[tex]A=\cos^{-1}\dfrac{1151}{1680}[/tex]
[tex]A=46.75503[/tex]
[tex]A\approx 47[/tex]
Therefore, the measure of the angle opposite the 46 foot side is 47 degrees.

Answer:
x = 47°
Step-by-step explanation:
From the picture attached,
CPD is a straight line.
Therefore, ∠CPB and ∠DPB is a linear pair of angles.
And linear pair of angles are supplementary.
By the property of linear pair of angles,
m∠CPB + m∠DPB = 180°
133 + x = 180
x = 180 - 133
x = 47°
a box contains 18 blue flashlights 3 red flashlights 7 silver flashlights ans 2 black flashlights. the flashlights are identical in size and shape. if one flashlight is chosen at random what is the probability that the flashlight will be either blue or black?
Answers
Answer:
The answer is 20/30 or in simplified form 2/3
Step-by-step explanation:
The way I do it is I take the probability of blue flashlights, 18/30, added to the probability of black flashlights, 2/30. Then, you simplify by dividing both numbers by 10.

Given the isosceles trapezoid EFGH and side length JL = 93 units. If the length of KN = (3x + 1) and MN = (5x - 4), what is the length of KM?
Answers
Answer:
KM=JL=93 units
or KM=KN + MN= 8x-3
Step-by-step explanation:
The value of length of KM can be equal to either JL or obtained by adding KN = (3x + 1) and MN = (5x - 4) depending on the diagram.
An isosceles trapezoid has non parallel sides congruent.
In the isosceles trapezoid the diagonals are also equal.
There is a pair of parallel lines in an isosceles trapezoid.
In the 1st figure trapezoid JL and KM are diagonals.
If we take the JM and KL to be the parallel lines then the opposite sides can be JK and LM
And N is the middle line or the mid segment.
In the figure 2
The value of length of KM is obtained by adding KN = (3x + 1) and MN = (5x - 4)
KM=KN + MN = (5x - 4) +(3x + 1)
KM=8x- 3
A triangle has two sides of length 17 and 19. What is the smallest possible whole-number length for the third side?
Answers
Answer:
3
Step-by-step explanation:
A triangle has two sides of length 17 and 19. What is the smallest possible whole-number length for the third side?
To solve for the above question, a rule applies.
The rule states that:
The sum of any 2 sides must be greater than than the third side.
The possible values for the third side are
19 - 17 < x < 19 + 17( x is the third side )
2 < x < 36
Thus the smallest possible whole number is 3

.find the slope and y intercept form equation from the table
Answers
Answer:
y = 4x - 26
Step-by-step explanation:
The change in y is 4 when the change in x is 1.
So the slope is change in y/change in x = 4/1 = 4
y = mx + b
30 = 4(14) + b
30 = 56 + b
b = - 26
Therefore, y = 4x - 26

48
Next lets do (8*12)-thats the middle rectangle
48+ 96
Now the triangles.
you can just do 2*8/2 because a triangle is half of a rectangle.
48+ 96+ 8
add 8 again because theres 2 triangles-
48+96 + 8 +8
Your answer is 160
