Answer:
x=1
Step-by-step explanation:
3x+6=9
3x=3
x=1
Answer:
X=1
Step-by-step explanation:
if you take away 6 from each sides it will leave you with 3 X's on the left and three 1's on the right. If the equation is equal then each X should match up with a 1. which makes each side equal to nine. Hope that helped :)))
A motorcycle tire with a radius of 16 inches rotates at a rate of 150 revolutions per minute (rpm).
a) Find the linear speed of the tire in inches per minute.
b) Find the angular speed of the tire in radians per minute.
Answer: (a)942.85 rad/s
(b) 15,085.71 inches per minute
Step-by-step explanation:
Given
the radius of tire r=16 inches
N=150 revolution per minute(rpm)
So, the angular speed of the tire [tex]\omega=2\pi N=2\times \frac{22}{7}\times 150=942.85\ rad/minute[/tex]
The linear speed of the tire [tex]v=\omega r[/tex]
[tex]v=\dfrac{6600}{7}\times 16=15,085.71\ \text{inches per minute}[/tex]

If m<IHF=75°, then what is m<EHK?
Simply here we can see ID is a straight line.
So, angle IHL + angle EHK = 180°
or, 75° + angle EHK = 180°
or, angle EHK= 105°
Hope it helps uh.
PLSS HELP WILL MARK BRAINLIEST!
Answer:
y = 5
Step-by-step explanation:
The triangle is an isosceles triangle, which means that it has two equal sides and two equal angles.
Therefore, angles B and C are both equal to 75°.
A triangle measures 180°.
75 + 75 + x = 180
150 + x = 180
x = 30°
Angle A has to equal 30°.
(4y + 10)° = 30
4y + 10 - 10 = 30 - 10
4y = 20
y = 5
Hope that helps.

Answer:

Step-by-step explanation:
You have two regular polygons
A & B
. The ratio of the interior angles of
A & B
is
21: 22
. The ratio of the exterior angles is
3:2
. How many sides does each polygon have?
Answer:
First polygon has 16 sides
Second polygon has 24 sides
Step-by-step explanation:
Let the number of sides for first polygon be a and that for the second polygon be b
formula for sum of interior angle is;
180n-360
So for individual interior angle we have;
(180n-360)/n
So for polygon A
(180a-360)/a
For polygon B
(180b-360)/b
Let’s divide both to equate to the ratio
(180a-360/a)/(180b-360)/b) = 21/22
Factor out 180
(a-2)/a * b/b-2 = 21/22
b(a-2)/a(b-2) = 21/22
22b(a-2) = 21a(b-2) •••••• (i)
For the second part
Sum of exterior angle of any polygon is 360
Individual exterior angle is 360/n
for the first polygon;
360/a ;
For the second 360/b
Thus;
b/a = 3/2
2b = 3a ••••••••(ii)
b = 3a/2
11(2b)(a-2) = 21a(b-2)
11(3a)(a-2) = 21a( 3a/2-2)
33a(a-2) = 21a(3a-4)/2
22a(a-2) = 7a(3a-4)
22a^2 - 44a= 21a^2-28a
22a^2-21a^2+28a - 44a = 0
a^2 + 28a - 44a = 0
a^2 -16a = 0
a(a-16) = 0
a = 0 (which cannot be)
or a-16 = 0
a = 16
Recall;
b = 3a/2
b = 3(16)/2
b = 24
