Find the value of x by using the exterior angle theorem.
Answers
Answer:
The first choice (12)
Step-by-step explanation:
i'm not 100% what the theory is but here is how I did it:
the angle D and 115% are supplementary which means they add up to 180.
115+x=180
x=65
so now that you know all the angle measures, you also know that all angles of a triangle add up to 180.
65+3x+19+5x=180
combine like terms:
8x+84=180
subtract 84 from both sides:
8x=96
divide by 8 on both sides
x=12

B. The new volume is 9 more than the old volume.
O C. The new volume is 9 times the old volume,
D. The new volume is 27 more than the old volume,
O E. The new volume is 27 times the old volume,
Answers
9514 1404 393
Answer:
E. The new volume is 27 times the old volume
Step-by-step explanation:
If L, W, and H are the original length, width, and height, then the original volume is ...
V = LWH
The volume after the scale factor is applied is ...
V' = L'W'H' = (3L)(3W)(3H) = 27LWH = 27V
The new volume is 27 times the old volume.

5 feet per second
Step-by-step explanation:
Given that,
X(seconds) 0 1 2 3 4
Y (feet) 0 1 4 9 16
We need to find the average rate of change between 1 seconds and 4 second.
X = 4-1 = 3 seconds
Y = 16 - 1 = 15 feet
We know that,
Speed = distance/time
So,
[tex]v=\dfrac{15}{5}\\\\v=5\ ft/s[/tex]

Find the indicated side of the triangle.
b
45°
28
a
a =
Enter
Answers
Answer:
a = 28 / √2
Step-by-step explanation:
Isosceles triangle therefor a = b
use pythagorean theorem
a² + a² = c²
2a² = 28²
a² = 28² / 2
Take the square root of both sides
a = 28 / √2
Answer:
a = [tex]\frac{28}{\sqrt{2} }[/tex]
Step-by-step explanation:
Using the sine ratio in the right triangle and the exact value
sin45° = [tex]\frac{1}{\sqrt{2} }[/tex] , then
sin45° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{a}{28}[/tex] = [tex]\frac{1}{\sqrt{2} }[/tex] ( cross- multiply )
a × [tex]\sqrt{2}[/tex] = 28 ( divide both sides by [tex]\sqrt{2}[/tex] )
a = [tex]\frac{28}{\sqrt{2} }[/tex]
How do I complete this question on arc length?
Answers
Answer:
v ≈ 8.5 km/h
Step-by-step explanation:
Since the diameter of the wheel is 3 m the radius will be r = 1.5 m.
Use the radius of the water wheel to find it's circumference C:
[tex]C=2\pi r[/tex] [set r = 1.5 m]
⇒ [tex]C=2\pi (1.5)[/tex]
⇒ [tex]C=3\pi[/tex] m
One revolution of the water wheel corresponds to [tex]3\pi[/tex] meters so the angular velocity 15 rmp (revolutions per minute) corresponds to:
[tex]15(3\pi )[/tex] = [tex]45\pi[/tex] [tex]m[/tex]/min
Using this result, the speed of the river in kilometers per hour will be:
[tex]v=\frac{45\pi m }{1 min}[/tex] × [tex]\frac{1 km}{1000 m}[/tex] × [tex]\frac{60 min}{1 h}[/tex]
⇒ [tex]v=8.48230016469[/tex] [tex]km/h[/tex]
⇒ [tex]v[/tex] ≈ [tex]8.5[/tex] km/h
Answer:
≈ 8 km per hour
Step-by-step explanation:
C = [tex]\pi[/tex] d
C = [tex]\frac{66}{7}[/tex]
Velocity = [tex]\frac{66}{7}[/tex] × 15 = [tex]\frac{990}{7}[/tex] ( meters per minute ) = [tex]\frac{0.99}{7}[/tex] × 60 ≈ 8.5 km/h

4x-3y<16, which ordered pair?
Answers
Answer:
A. (3, -1)
Step-by-step explanation:
The ordered pair that is a solution is the one which makes the inequality TRUE when the value of the ordered pairs are plugged into 4x - 3y < 16
Therefore, the ordered pair, (3, -1) is the solution because it is the only given ordered pair in the options that makes the inequality true. Thus:
Substitute x = 3 and y = -1 into 4x - 3y < 16
4(3) - 3(-1) < 16
12 + 3 < 16
15 < 16 (TRUE)
