M = Tim's dollar amount
R = Rebecca's dollar amount
MR = Tim and Rebecca's dollars together
R = (M x 1/10) - 6
MR = M + ((M x 1/10) - 6)
MR = 70 + ((70 x 1/10) - 6)
MR = 70 + (7 - 6)
MR = 70 + 1
MR = 71
The net that can be folded to form a pyramid is A net has a square at the center. 2 triangles are on 1 side, and 2 triangles are on another side.
<h3>What is a net?</h3>
A net is a two-dimensional representation of a three dimensional solid object showing its faces.
Examples of material which can have nets are
- cubes,
- cuboids
- prisms etc
<h3>What is a pyramid?</h3>
Now, for a pyramid, we know that a pyramid is a three dimensional solid object that has one square base and four triangular sides.
So, when a pyramid is split into its net, it will have one square at the center and four triangles on the sides of the squares.
So, the net that can be folded to form a pyramid is A net has a square at the center. 2 triangles are on 1 side, and 2 triangles are on another side.

Ф=angle between the ladder and the ground.
cos Ф= adjacent / hypotenuse
cos Ф=1.5 m / 4 m=0.375
Ф=arccosine 0.375=67.98º≈68º
The angle between the ladder and the ground is 68º
Answer:
A) 27 degrees
Step-by-step explanation:
Arc length = fraction of the circle * circumference
Arc length = fraction of the circle * 2 * pi *r
3/4 pi = fraction of the circle * 2 * pi *5
3/4 pi = fraction of the circle *10 pi
Divide each side by 10pi
3/4 pi
-------- = fraction of a circle
10 pi
3/40 = fraction of a circle
A circle is 360 degrees
3/40 = x/360
Multiply by 360
3/40 *360 = x
27 = x
Answer:
Answer: B. 24
Step-by-step explanation: 60 divided by 5 is 12. Twelve times two (the amount of girls) is 24. Twelve times 3 (the amount of boys) is 36. Since 24 + 36 = 60, there are 24 girls and 36 boys.
