Answer:

5x^2(x^2 + 2x + 3)

Step-by-step explanation:

All the terms can be factored by 5 and x^2, so we get:

5x^2(x^2 + 2x + 3)

there are no more common terms so this is the answer

Answer:

16

Step-by-step explanation:

The sum of the exterior angles of a polygon = 360°

Divide by 22.5 to find the number of sides n

n = [tex]\frac{360}{22.5}[/tex] = 16

It an be concluded tat the regular polygon has 16 sides

A regular polygon is a polygon with equal angles and equal sides.

The sum of exterior angles of a regular polygon is 360°

According to the given data

One exterior angle of a regular polygon measures 22.5 °

Let us consider that the regular polygon has "n" sides

So from the exterior angle sum property of the regular polygon we can write that

[tex]\rm n \times 22.5\textdegree = 360 \textdegree\\ n = 360\textdegree /22.5\textdegree \\n = 16[/tex]

So it an be concluded tat the regular polygon has 16 sides

Answer:

Triangles 3 and 4 are both isosceles. They each have a 60 degree angle.

This is a similar triangle.

Step-by-step explanation:

Isosceles triangle is one in which two sides are equal.

Similar triangles are triangles which have all corresponding angles equal and which have corresponding sides with the same ratio.

Now the given isosceles triangle both have all three angles equal to 60 degrees which makes them similar triangles.

The other choices given are not similar triangles because

1) they do not have all corresponding angles equal

2) their lengths are unknown and cannot be assumed to be in ratio.

[tex]\sqrt{53}[/tex]

Step-by-step explanation:

Calculate the distance d using the distance formula

d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]

with (x₁, y₁ ) = (- 5, 8) and (x₂, y₂ ) = (- 3, 1)

d = [tex]\sqrt{(-3+5)^2+(1-8)^2}[/tex]

   = [tex]\sqrt{2^2+(-7)^2}[/tex]

Answer: 5.86yd

Step-by-step explanation:

From the question, we are informed that Esteban stands on a dock 1.25 yd above the water and that a fish swims below Esteban at -4.61 yd from the surface of the water.

The distance between Esteban and the fish can be calculated by subtracting -4.61 yd from 1.25 yd. This will be:

= 1.25 yd - (-4.61 yd)

= 1.25 yd + 4.61 yd

= 5.86 yd

*see attachment for the dimensions of the cone given.

Answer:

7.9 in³

Step-by-step explanation:

Given:

Height of cone = 4 in.

Diameter of cone = 2¾ in

Radius (r) = ½ of 2¾ = 1.375 in

Required:

Volume of the cup

Solution:

Volume of the cup = volume of a cone

Volume of a cone = ⅓πr²h

Plug in the values of π, r and h into the formula.

Volume = ⅓*3.14*1.375²*4 = 7.9 in³ (approximated to the nearest tenth)

Answer:

The total area of the field is 343 square feet

Step-by-step explanation:

Let us solve the question

∵ There are 7 workers hired to seed a field by hand

∵ Each is given a plot 7 x 7  feet in size

→ The plot has shaped a square because its two dimensions equal

∴ The side of the plot = 7 feet

∵ The area of the square = side × side

∴ The area of each plot = 7 × 7

∴ The area of each plot = 49 square feet

→ To find the total area multiply the area of 1 plot by the number

   of the workers

∵ The total area = 49 × 7

∴ The total area = 343 square feet

∴ The total area of the field is 343 square feet

Answer:

the unit price needed to calculate is $0.8 per mile

Step-by-step explanation:

Here is the complete question:

At a​ little-known vacation​ spot, taxi fares are a bargain. A 14 Mile Taxi ride takes 16 minutes and costs $11.20 you want to find the cost for a 49 mile taxi ride . What unit price do you​ need?

Step-by-step explanation:

To determine the unit price needed to calculate the cost for a 49 mile taxi ride, we will determine the cost of the ride per mile. To do this, let the cost per mile be $x

If it cost $11.20 for a 14 mile ride

Then, it will cost $x for a 1 mile ride

∴ x = (1 × 11.20) / 14 = 0.8

x = 0.8

The taxi ride costs $0.8 per mile.

Hence, the unit price needed to calculate is $0.8 per mile.

If desired,

To find the cost for a 49 mile taxi ride, multiply the distance traveled by the unit price,

Distance = 49 mile

Unit price = $0.8 per mile

∴ Cost for a 49 mile taxi ride = 49 × $0.8

Cost for a 49 mile taxi ride = $39.2

Hence, the cost for a 49 mile taxi ride is $39.2

Answer:

You need a common denominator.

Step-by-step explanation:

3/4+2/3

9/12+8/12

Answer:

Equal denominators/common denominators

Step-by-step explanation:

You need to have equal denominators. If you do not, then you have to multiply the denominators against each other as well as multiplying the same number to the numerator. If a number is a factor of one of the numbers then multiply the number by its other factor so as to get the same number.

Ex. 1

First one explained:

2/3 + 4/5

1/3 * 5/5 = 5/15

2/5 * 3/3 = 6/15

5/15 + 6/15 = 11/15

Ex. 2

Second one explained:

2/8 + 1/4

2/8 + 1/4*2/2 = 2/8 + 2/8

= 4/8

Answer:

8 books

Step-by-step explanation:

1 book = 1 1/2 inches

Length of the shelf = 12 inches

Hence,

3/2 inches = 1 book

12 inches = x

3/2 × x = 12 × 1

x = 12 ÷ 3/2

12 × 2/3

4 × 2

= 8 books

Hence, he can put 8 books side-by-side on the shelf.
