Answer:
inches
Step-by-step explanation:
pretty sure that says 41 inches because at 36 it says 3 feet and 12 inches = 1 feet, so 36 inches equal 3 feet. The measurement would be inches.

[tex]\frac{25}{20}=\frac{30}{4x-4}\\\frac{30}{1.25}=4x-4\\x=7[/tex]
Answer:
x = 7
Step-by-step explanation:
I'm assuming ΔJKL and ΔMNP are similar as you wouldn't be able to solve it otherwise. ∠J≅∠M and ∠K≅∠N, so I assume its just a poorly formed question.
With that assumption made, if 2 triangles are similar, the scale factor on all sides are equal. That means this:
[tex]\frac{JK}{MN} =\frac{JL}{MP}[/tex]
The scale factor is just the new length divided by the old length, and that equation shows the scale factor on both of those side lengths are the same. With 3 of the 4 side lengths, you can plug those values in and solve for the last unknown.
[tex]\frac{25}{30} =\frac{20}{4x-4}[/tex]
I use cross multiplication here:
[tex]25(4x-4)=20(30)\\100x-100=600\\100x=700\\x=7[/tex]

E = (-52) + 13 + 49 + (-15) + (-36) + 82
Answer:
E = 41
Step-by-step explanation:
E = (-52) + 13 + 49 + (-15) + (-36) + 82
Take the -ve terms to one side and +ve terms to the other.
E = (13 + 49 + 82) - 15 - 36 - 52
E = 144 - 103
E = 41
Mark was thinking of a number. Mark adds 1.7 to the number, then doubles the result to get an
answer of 42.7. Form an equation with x
Answer:
2(x + 1.7) = 42.7
Step-by-step explanation:
"adds 1.7 to the number" represents x + 1.7"then double the result" combined with "adds 1.7 to the number" represents 2(x + 1.7) "answer of 42.7" combine with all of the above makes 2(x + 1.7) = 42.7reorder the steps of the proof to make sure that steps that are logically dependent on prior steps are in the proper order.

find the measure indicated angle that makes lines u and v parallel
Answer:
91°
Step-by-step explanation:
The answer is 91°. What you do is you name the angle next to 89° with x, and you know that an angle whose arms are horizontal makes 180°. So, you go:
180°=x+89°
x=180°-89°
x=91°.
Now, there is this rule that says that when two angles are on sides like x and ? are, then they are equal. Therefore, the angle marked with ? is 91°.
Which statement is true
Answer:
[tex]xv=yu[/tex]
Step-by-step explanation:
You can simplify the equation by cross multiplying, or doing it the more 'correct' way that some teachers way want:
[tex]\frac{x}{y}=\frac{u}{v}[/tex]
Multiply both sides by y:
[tex]x=\frac{yu}{v}[/tex]
Then multiply both sides by v:
[tex]xv=yu[/tex]

h = 2 + 32t - 16t^2 is the function given to model the balls flight and we want to know what time the ball is at 15 feet in the air, which is at 2 points in time since the ball takes a parabolic trajectory.
15 = 2 + 32t - 16t^2
0 = -16t^2 + 32t -13
since the equation isn't factorable we will use the quadratic formula.
(-b +- sqrt(b^2 - 4ac))/2a

Given that p varies directly as q and
[tex] \sqrt{q} [/tex]
varies inversely with t², show how p varies with t.
Answer:
Above is the step-by-step solution
[tex]\\ \sf\longmapsto p\propto q [/tex]
[tex]\\ \sf\longmapsto p=kq[/tex]
Divide both sides by q[tex]\\ \sf\longmapsto \dfrac{p}{q}=k[/tex]
[tex]\\ \sf\longmapsto q=\dfrac{p}{k}[/tex]
Now
[tex]\\ \sf\longmapsto p\propto \sqrt{q}[/tex]
[tex]\\ \sf\longmapsto p\propto \dfrac{1}{t^2}[/tex]
[tex]\\ \sf\longmapsto p=\dfrac{k}{t^2}[/tex]
Substitute√q[tex]\\ \sf\longmapsto \sqrt{q}=\dfrac{k}{t^2}[/tex]
[tex]\\ \sf\longmapsto q=\dfrac{k^2}{t^4}[/tex]
Substitute q=p/k[tex]\\ \sf\longmapsto \dfrac{p}{k}=\dfrac{k^2}{t^4}[/tex]
[tex]\\ \sf\longmapsto p=\dfrac{k}{t^4}[/tex]
[tex]\\ \sf\longmapsto p\propto \dfrac{1}{t^4}[/tex]

Answer:
n = 55
n+15 = 70
2n = 110
Step-by-step explanation:
these angles are called 'same-side interior angles' and are supplementary
so we can add them together and set them equal to 180
n+15 + 2n = 180
combine 'like terms' to get:
3n + 15 = 180
subtract 15 from each side to get:
3n = 165
divide each side by 3 to solve for 'n'
n = 165/3
n = 55
substitute 55 for 'n'
55+15 = 70
2(55) = 110
check: 70 + 110 = 180
I need help finding this answer
y = -2x - 4
--> Swap sides so that all variable terms are on the left hand side
-2x - 4 = y
--> Add 4 to both sides
-2x = y + 4
--> Divide both sides by -2
-2x/-2 = y+4/-2
--> Dividing by -2 undoes the multiplication by -2.
x = y+4/-2
--> Divide y+4 by -2
x = -y /2 -2
-------------------------------------------------------------
y = 1/4x + 5
--> Swap sides so that all variable terms are on the left hand side.
1/4x + 5 = y
--> Subtract 5 from both sides.
1/4x = y - 5
--> Multiply both sides by 4.
1/4x 1/4 = y - 5/ 1/4
--> Dividing by 1/4 undoes the multiplication by 1/4.
x = y - 5/ 1/4
--> Divide y - 5 by 1/4 by multiplying y - 5 by the reciprocal of 1/4.
x = 4y - 20
Hope this helps you!
A cyclist travels at an average speed of 11 mph for 3 hours. How far did she travel in miles?
Answer:
33 miles
Step-by-step explanation:
The cyclist traveled for 3 hours ar 11 miles per house to find how many miles she traveled simply multiply the speed times the amount of time traveled 11 times 3 is 33
1 hour = 11 miles
3 hours = 11 x 3 miles
= 33 miles.
Ans: 33 miles

Answer:
e)
a = 58°
alternate angles
b = a = 58°
Triangle is scalene (indicated by the 2 dashes on the triangle)
d = 180 - (58*2)
d = 64°
c = 58°
use either 180- (64+58)
which is angles in a straight line = 180 total
or
alternate angles
b = c = 58
f) x = 50°
alternate angles
y+z = 180-50
y+z = 130
we know that y = z
scalene triangle indicated by arrows (both bases are same angle)
so 130/2 = y and z
65 = y
65 = z
g) x = 55
alternate angles
on the diagram take the triangle which has x and y
you can see 95° outside the triangle, it’s on a straight line and will help us find the third angle for that triangle
180-95 = 85
180 - (85+55) = y
y = 40
z = y = 40
alternate angles
h)
180-78 = 102
beside angle a would be the angle 2a
alternate angles (look at the photo)
180 = 102 + a + 2a
180 = 3a + 102
78 = 3a
a = 26°
2a = 52
b = 26
use either alternate angles
a = b
or total angles in a triangle = 180°
102 + b + 56 = 180
b = 180-52-102

Which expression is equivalent to 21 x + 35 y – 14 = 0?
y = x + 2
B y = x – 7
C y = -x + 14
D 3x + 5y = 2
Answer: D: 3x + 5y = 2
Step-by-step explanation:
D. Divide 21 x + 35 y – 14 = 0 by 7 to get:
3x + 5y -2 = 0
Rearrange: 3x + 5y = 2
Calculate the height of a tree whose shadow is 20m shorter when the angle of elevation of the sun is 60° than when it's 30°.
Answer:
17.3 m
Step-by-step explanation:
If t is the height of the tree, then the length of the shadow is ...
shadow length = t/tan(α)
where α is the angle of elevation. The difference in shadow lengths is ...
20 m = t/tan(30°) -t/tan(60°) = t(√3 -1/√3)
t = (20 m)/(2/√3) = 10√3 m ≈ 17.3 m
The tree is about 17.3 meters high.
