6 0

Answer:

145°

Step-by-step explanation:

x°+70°=(2x-5)°

x°+70°=2x°-5°

70°+5°=2x°-x°

75°=x°

x=75

JKM=(2x-5)°

=(2x75-5)°

=(150-5)°

=145°

Taiga wants to make a circular loop that she can twirl around her body for exercise. He will use a tube that is 2.5 meters long.
Travka [436]

Answer: 0.796 meters

Step-by-step explanation:

Circumference of circle = 2\pi r , where r=radius

Here, Circumference of loop = 2.5 meters

i.e. 2\pi r=2.5

\Rightarrow\ r=\dfrac{2.5}{2\pi}

\Rightarrow\ r=\dfrac{2.5}{2\times\dfrac{22}{7}}\\\\\Rightarrow\ r=\dfrac{2.5\times7}{2\times22}\\\\\Righttarrow\ r=0.398\ m

Diameter = 2r = 2(0.398) = 0.796 meters

Hence, The diameter of Taiga's exercise hoop = 0.796 meters

Natali5045456 [20]

\bf ~~~~~~~~~~~~\textit{distance between 2 points}\\\\A(\stackrel{x_1}{4}~,~\stackrel{y_1}{-7})\qquadB(\stackrel{x_2}{-2}~,~\stackrel{y_2}{1})\qquad \qquadd = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2}\\\\\\AB=\sqrt{[-2-4]^2+[1-(-7)]^2}\implies AB=\sqrt{(-2-4)^2+(1+7)^2}\\\\\\AB=\sqrt{(-6)^2+8^2}\implies AB=\sqrt{36+64}\implies AB=\sqrt{100}\implies AB=10

There are many cylinders with a height of 9 inches. Let R represent the radius in inches and V represent the volume in cubic inc
PtichkaEL [24]

Answer:

R V

1  9π in³ 

2  36π in³

3  81π in³

Step-by-step explanation:

For, r = 1

V = π(1)²9 = 9π in³

For, r = 2

V = π(2)²9 = 4*9π in³ = 36π in³

For r = 3

V = π(3)²9 = 9*9π in³ = 81π in

R V

1  9π in³ 

2  36π in³

3  81π in³
