Answer:

5 units

Step-by-step explanation:

the length of CD can be determined using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

3² + 4²

= 9 + 16

= 25

Answer:

D. 140

Step-by-step explanation:

∠ 1 + ∠ 2 = 180

So:

(3x + 20) + x = 180

4x + 20 = 180

4x = 180 - 20

4x = 160

x = 160 / 4

x = 40

∠ 1 = ∠ 4

∠ 2 = ∠ 3

If ∠ 1 is equal to ∠ 4, just plug in for x and solve.

3x + 20 = 3(40) + 20 = 120 + 20 = 140

Answer:

Answer is 256 degrees

Step-by-step explanation:

You basically take the degree that they gave you, which is 104, now take 360 (that's the measurement of the whole circle) and subtract it by 104 to get your answer.

Step-by-step explanation:

[tex]a^{2} +b^{2} =c^{2} \\4^{2} + 5^{2} = 16 + 25 = \sqrt{41} = c[/tex]

Answer:

6.4

Step-by-step explanation:

As we can see it is a right angled triangle so

perpendicular (p)= 5

base (b) = 4

hypotenuse (h) = c = ?

we know

by using Pythagoras theorem,

h² = p² + b²

or h = √(p² + b²)

c = √( 5² + 4 ² )

c = √41

c = 6.4

Answer: 1¼ pounds

Step-by-step explanation:

Since 20 pounds of beans are distributed equally into 16 bags to give out at the food bank, the amount of pounds of beans that are in each bag will be gotten by dividing 20 by 16 which will be:

= 20 pounds / 16

= 1¼ pounds

Therefore, there are 1¼ pounds of beans in each bag.

Answer:

tan x = -3 (Answer A)

Step-by-step explanation:

We want to find the tangent of this angle "theta," and recall the trig identity

(sin x)^2 + (cos x)^2 = 1.

               3√10

If sin x = -----------

                   10

                             90

then (sin x)^2 = ----------- = 9/10

                             100

and (cos x)^2 = 1 - 9/10 = 1/10

                      sin x       3√10/10

Then tan x = ---------- = -------------- = -3 (Answer A)

                       cos x      1√10/10

The tangent function is negative in Quadrant II.  In Quadrant I tan x = +3

Answer:

A

Step-by-step explanation:

Using the trig identity

sin²x + cos²x = 1 , then cos x = ± [tex]\sqrt{1-(\frac{3\sqrt{10} }{10})^2 }[/tex]

Given

sinθ = [tex]\frac{3\sqrt{10} }{10}[/tex] , then

cosθ = ± [tex]\sqrt{1-(\frac{3\sqrt{10} }{10})^2 }[/tex]

        = ± [tex]\sqrt{1-\frac{9}{10} }[/tex]

        = ± [tex]\sqrt{\frac{1}{10} }[/tex]

Since θ is in second quadrant where cosθ < 0 , then

cosθ = - [tex]\frac{1}{\sqrt{10} }[/tex]

Then

tanθ = [tex]\frac{sin0}{cos0}[/tex] = [tex]\frac{\frac{3\sqrt{10} }{10} }{\frac{-1}{\sqrt{10} } }[/tex] = - 3 → A

Answer:

y=63, x=20, x=47, b=70, c=89, x=133

Step-by-step explanation:

1) y=63- alternate angles are the same

2) 4x+5x=180

9x=180

x=20

3) x=47

4) b=70- angles on a line equal to 180

c=89- angles in a triangle add up to 180

5) x=133- angles that are alternate are the same

It is a three-dimensional shape with two parallel circular bases and a curve surface.

The volume of water needed to fill the pool is 180π square feet.

It is a three-dimensional shape with two parallel circular bases and a curve surface.

Volume = π r² h

r = radius of the cylinder

h = height of the cylinder

We have,

Diameter of the cylinder = 12 ft

Radius = diameter/2 = 12/2 = 6 ft

Height of the cylinder = 5 ft

The volume of the cylinder:

=  πr²h

=  π x 6² x 5

= π x 36 x 5

= 180π square feet

Thus,

The volume of water needed to fill the pool is 180π square feet.
