The parallelogram shown below has an area of 54 units^2 squared. Find the missing height. h = units.
Answer:
See Explanation
Step-by-step explanation:
This question requires an attachment.
However, if you follow my explanation, you'll arrive at your answer
The area of a parallelogram is:
[tex]Area (A)= Base (b) * Height (h)[/tex]
[tex]A = b * h[/tex]
To solve for Height, we simply make h the subject of formula
[tex]h = \frac{A}{b}[/tex]
In this question, we have that A = 54
Now, let's assume base (b) = 6.
This implies that
[tex]h = \frac{54}{6}[/tex]
[tex]h = 9[/tex]
Or;
Assume that b = 3
[tex]h = \frac{54}{3}[/tex]
[tex]h = 18[/tex]
So, whatever the base of the parallelogram is;
You can easily solve for the height using the above steps
is angle 2 in the diagram and angle of elevation or an angle of depression
Answer:
Angle of elevation
Step-by-step explanation:
An angle measured from the horizontal upwards is an angle of elevation.
An angle measured from the horizontal downwards is an angle of depression.
∠ 2 is a measure from the horizontal upwards thus angle of elevation.
Note that ∠ 3 is an angle of depression

A vertical pole is placed in the ground at a campsite outside Salt Lake City, Utah. One winter day, 16 of the pole is in the ground, 23 of the pole is covered in snow, and 1.8 ft is above the snow. How long is the pole, and how deep is the snow
Answer:
Length of the pole = 10.8 ft
Depth of the snow = 7.2 ft
Step-by-step explanation:
The correct question is
A vertical pole is placed in the ground at a campsite outside Salt Lake City, Utah. One winter day, 1/6 of the pole is in the ground, 2/3 of the pole is covered in snow, and 1.8 ft is above the snow. How long is the pole, and how deep is the snow.
The fraction of the pole in the ground = 1/6
The fraction of the pole in the snow = 2/3
The length of the pole above the snow = 1.8 ft
Total fraction of the length of the pole = 1
For the fraction of the length above the snow, we solve as
1/6 + 2/3 + [tex]x[/tex] = 1
[tex]x[/tex] = 1 - 1/6 - 2/3 = 1/6
This means that the length of the pole above the snow 1.8 ft = 1/6 of the length of the pole.
Also, the fraction of the pole in the ground = 1/6
this means that the length of the pole in the ground = 1.8 ft
If 1/6 of the length of pole is 1.8 ft,
the length of the pole = 1.8 ft x 6 = 10.8 ft
Length of the pole in the snow = 2/3 of 10.8 = 2/3 x 10.8 = 7.2 ft
this means that the the snow is 7.2 ft deep
a manned rocket accelerates at a rate of 20 m/s2 during launch How long does it take the rocket reach a velocity of 400 m/s?
Answer:
Step-by-step explanation:
acceleration, a = 20 m/s^2
initial velocity, u = 0 since it starts from rest
final velocity, v = 400 m/s
v = u + at
400 = 0 + 20 t
400 = 20 t
t = 400 / 20
t = 20 sec
Hope this helps
plz mark as brainliest!!!!
It will take 20 sec the rocket reach a velocity of 400 m/s
What are equations of motion?There are three equation of motions that can be used when motion of the object is under constant acceleration and on a straight path.
They are listed below as:
[tex]v = u + at\\\\s = ut + \dfrac{1}{2} at^2\\\\v^2 = u^2 + 2as[/tex]
We are given that manned rocket accelerates at a rate of 20 m/s2 during launch
The acceleration, a = 20 m/s^2
The initial velocity, u = 0 since it starts from rest
The final velocity, v = 400 m/s
Therefore, v = u + at
400 = 0 + 20 t
400 = 20 t
t = 400 / 20
t = 20 sec
Hence, It will take 20 sec the rocket reach a velocity of 400 m/s

Which of the following is a correct comparison of two rational numbers?a. 1.5 > 5/3b. 2.5 < 0.25c. 0.07 > 7/10d. 0.6 > 4/7
Answer:
d. 0.6 > 4/7
Step-by-step explanation:
a. 1.5 > 5/3
From part a, it is given that 1.5 is greater than 5/3
changing 5/3 to decimal figure, we get 1.67
Thus, the claim that 1.5 > 1.67 is not valid because 1.67 is greater than 1.5
b. 2.5 < 0.25
given that 2.5 is less than 0.25 is not valid because 2.5 is greater than 0.25
c. 0.07 > 7/10
if we convert 7/10 to decimal figure, we get 0.7
the claim that 0.07 is greater than 0.7 is not valid because 0.7 is greater than 0.07
d. 0.6 > 4/7
If we convert 4/7 to decimal figure, we get 0.57
Therefore, the claim that 0.6 is greater than 0.57 is accurate and valid
Hence, Option d is the correct answer.

Find the value of term a14 in the sequence. 7, 2, -3, -8, -13...
Answer:
-58
Step-by-step explanation:
The first term (a₁) is 7 and the common difference (d) is 2 - 7 = -5.
Explicit formula of arithmetic sequence: aₙ = a₁ + (n - 1) * d
aₙ = 7 + (n - 1) * (-5) = 7 - 5n + 5 = -5n + 12
Therefore, a₁₄ = -5 * 14 + 12 = -58.

If k3 – 9 = 12, what is the value of k? A. 1 B. 7 C. 9 D. 63
Answer:
63
Step-by-step explanation:
The answer is 63 because k/3 =63
k/3-9=12
We move all terms to the left:
k/3-9-(12)=0
We add all the numbers together, and all the variables
k/3-21=0
We multiply all the terms by the denominator
k-21*3=0
We add all the numbers together, and all the variables
k-63=0
We move all terms containing k to the left, all other terms to the right
k=63

Find the equation of a line that is perpendicular to the line -2y+20=8x and passes through the point (7,2).
Answer:
8y -2 = 2x
Step-by-step explanation:
The equation of the perpendicular line will have the coefficients of x and y swapped, and one of them negated. The constant can be found by substituting the given point value:
8y +constant = 2x . . . . coefficients swapped; former y-coefficient negated
8(2) +constant = 2(7) . . . . . fill in given point values (x, y) = (7, 2)
constant = 14 -16 = -2 . . . . subtract 16
The equation can be written as ...
8y -2 = 2x
_____
Additional comment
Personally, I prefer standard form, which has common factors removed from the coefficients, and has the constant separated from the variable terms:
x -4y = -1
Some like the slope-intercept form better:
y = 1/4x +1/4
Apparently, your curriculum author doesn't care how the equation of the line is written, so we have answered with the same form that was given.

hope it will help ^_^
Answer:
[See Below]
Step-by-step explanation:
First you'll solve the parenthesis part:
* 12 - 3 = 9
Then Solve the exponents:
* 4^4 = 256 (4 x 4 x 4 x 4)
* 3^3 = 27 (3 x 3 x 3)
Rewrite:
* 256 - 27 x 9 - 20
Multiply:
* 27 x 9 = 243
Subtract:
* 256 - 243 = 13
* 13 - 20 = -7
So the answer would be B, -7

Assuming that [tex]l[/tex] represents length and [tex]w[/tex] represents width, we can make a systems of equations and solve for l and w.
[tex]2l+2w=60[/tex], since the perimeter of a rectangle will be double the length plus double the width.
Also we can make the equation [tex]l = 2w+3[/tex], as stated in the last part of the question.
We can now substitute the value of [tex]2w+3[/tex] into the equation [tex]2l+2w=60[/tex] as l.
[tex]2(2w-3) + 2w = 60\\\\4w-6+2w=60\\\\6w-6=60\\\\6w=66\\\\w = 66\div6\\\\w = 11[/tex]
So we know the width is 11. Now that we know the width, we can substitute it back into the equation [tex]l = 2w+3[/tex] to find the length.
[tex]l=2\cdot11-3\\\\l=22-3\\\\l=19[/tex]
So the length is 19.

Answer:

Step-by-step explanation:
Add 4b and 8b, which you get 12b. Then you add 11 and 1 which you get 12.
12b + 12 = 180 is the next equation.
Afterwards, you subtract 12 from 180.
12b = 168
Divide 12b from 168.
b = 14
Find for B?
Mk in this equation
4b + 11 + 8b + 1 = 180
Subtract 11 and 1 from both sides
4b + 8b = 168
Combine unknowns
12b = 168
Find b by dividing by 12
Thus, B = 14

You need the starting point, and another point that helps direct where the ray is aimed. Call these two points A and B.
Saying "Ray AB" means we extend a line through AB such that the line goes forever through B and beyond B, but we do not do the same for point A. The point A is effectively a cliff where no road goes on the other side of it. Check out the diagram below to see what I mean. The arrow means the line goes on forever in that direction.
