The growth of Noah in the past year is 2 5/6 inches.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Noah stood 55 2/3 inches tall on his tenth birthday and he stood

58 1/2 inches on his 11th birthday.

Therefore, The growth of Noah is the difference between the heights on his tenth birthday and eleventh birthday which is,

= (58 1/2 - 55 2/3) inches.

= (117/2 - 167/3).

= (117×3 - 167×2)/6 inches.

= (351 - 334)/6 inches.

= 17/6 inches.

= 2 5/6 inches.

What are polygons?

A polygon is a plane figure described by a finite number of straight-line segments connected to form a closed polygonal chain in geometry. A polygon is defined as a bounded plane region, a bounding circuit, or both.

If the angles are congruent AND the sides are proportional, then the two polygons are similar.

If two objects are having the same shape then they will be termed as similar. So in mathematics, if two figures have the same shapes, lines or angles then they are called similar.

Answer:

72 cm³ (see below)

Step-by-step explanation:

First, refer to the volume formula:

V = l · w · h

If you plug in all of your values and simplify, you'll get the volume:

l = 6 cm

w = 3 cm

h = 4 cm

V = (6) (3) (4)

V = 18 (4)

V = 72 cm³

Because this is volume, the measurements are units cubed, meaning it's cm³.

Like he said 72cm3. Hope you get it right

The parallelogram below is being covered with carpet. The carpet is priced at $2.80 per square meter. How much will it cost to carpet the shape?

| 3.5 m

8.1 m

It will cost $ type your answer...

to carpet the shape

Answers

Answer:

It will cost $79.38 to carpet the shape

Explanation:

Find the diagram of the parallelogram attached

Area of a parallelogram = Base * Height

Given

Base = 8.1m

Height = 3.5m

Area of the parallelogram = 8.1*3.5

Area of a parallelogram = 28.35m²

Since 1m² = $2.80

28.35m² = x

Cross multiply

x = 28.35 * 2.80

Hence it will cost $79.38 to carpet the shape
