5 / 4 x + 3 = x - 1 / 4

tiny-mole [99]

5/4x+3 = x-1/4
5/4x-x = -1/4-3
1/4x = -13/4
x = -13/4.4
x = - 13

How are mountains and plateaus alike?

IgorLugansk [536]

Answer:

It is similar to a mountain in that it is dramatically higher than what is immediately around it. But mountains usually have a distinct apex or peak that is very small relative to the base and not typically level. Plateaus and mesas have tops only a little smaller than the base, and relatively flat. If the aspect ratio is less than 1, plateau. If greater than 1, mesa.

The stained glass window below is a semicircle. What is the distance around the window to the nearest hundredth of an inch? Use

Brrunno [24]

Answer:

The area of a circle is given by the formula

area=πr2

we have the value of π=3.14 , and the radius is taken from the diameter of the window (bottom edge), using the relation:

r=diameter

2r=362

r=18

By substituting these values to the formula of a circle, we now have:

area= (3.14 ) (18) 2

area=1017.36

But since the window is a semicircle, the area will have to be divided in half, therefore,

area of a semicircle =1017.362

area of a semicircle = 508.68

Thus the window's area is equal to 508.68 sq in.

A piece of paper has a

Allisa [31]

Answer:

The volume of the resulting cylinder is 385 cm³

Step-by-step explanation:

The formula of the rule of a cylinder is V = π r² h, where

r is the radius of its base

h is the height of it

When a rectangular paper folded to form a cylinder, then one of its dimension will be the circumference of the base and the other dimension will be the height of the resulted cylinder

∵ ABCD is a rectangle

∵ It is folded where AB coincides with DC

∴ AB is the height of the resulted cylinder

∴ BC is the circumference of the base of the resulted cylinder

∵ AB = 10 cm

∴ h = 10 cm

∵ BC = 22 cm

∴ The circumfrence of the base = 22 cm

∵ The circumference of a circle = 2 π r

→ Equate the rule by 22 to find r

∴ 2 π r = 22

∵ π = $\frac{22}{7}$

∴ 2 × $\frac{22}{7}$ × r = 22

∴ $\frac{44}{7}$ r = 22

→ Divide both sides by $\frac{44}{7}$

∴ r = 3.5 cm

→ Use the formula of the volume above to find the volume of the cylinder

∵ V = $\frac{22}{7}$ × (3.5)² × (10)

∴ V = 385 cm³

∴ The volume of the resulted cylinder is 385 cm³
