Answer 1
-8n+4+20n=-6n-14
12n+6n+4=-14-4
18n=-18
n=-1
Answer 2

Answer:

The student was supposed to multiply 4(1+5n)  to equal 4+20n instead she forgot to multiply 5n and put 4+5n.

Step-by-step explanation:

-8n + 4(1 + 5n) = -6n -14

-8n + 4 + 20n = -6n -14

12n+4 = -6n -14

+6n       +6n

18n +4 = -14

       -4    -4

      18n= -18

          n = - 1

The Pythagorean Theorem can be used to find the distance between points (3, 2) and (6, 4). Select all the points that could be the third vertex in the triangle.

Sorry, he gave you a false answer :/

Answer:

(3,4) and (6,2) could be vertices of a right triangle with (6,4) and (3,2)

(0,0) is on the same line as (6,4) and (3,2) so it doesn't even form a triangle, much less a right triangle.

(3,6) forms a scalene isosceles triangle, but not a right triangle  It's a 4-sqr13-sqr13 triangle

What is the value of x?

Answers

Answer: x = 27

Step-by-step explanation:

The angles (4x + 7) and 5(x - 4) are opposite angles formed by intersecting lines.

When intersecting lines form two sets of opposing angles, both pairs are equal in angle measure.

As such, the angles (4x + 7) and 5(x - 4) are equal. Knowing this, you can solve for x by setting the angles equal to each other in an equation:

[tex](4x + 7) = 5(x - 4)\\\\4x + 7 = 5x - 20\\\\27 = x[/tex]

X = 27.

Arionna is correct because there are 3 feet across the length of a cubic yard and 3 feet across the depth of a cubic yard. 3 times 3 = 9 Arionna is correct because there are 3 feet in a yard and there are 3 dimensions in a cubic yard: length, depth, and height. 3 times 3 = 9 Arionna is incorrect. There are only 3 cubic feet in a cubic yard because there are 3 feet in a yard, and the proportion will remain constant. Arionna is incorrect.

Here are the first five terms of a sequence.

3 8 17 30

47

Find an expression, in terms of n, for the nth term of this sequence.

Answers

Answer:

So the formula for the sequence is

Second term =first term + (a+nd)

Third term = second term + (a+nd)

And so on

Where n start with zero

Step-by-step explanation:

3 8 17 30 47

First term = 3

Second term = 8

Third term = 17

Fourth term = 30

Fifth term = 47

Second term - first term = 8-3=5

Third term - second term = 17-8= 9

Fourth term - third term = 30-17=13

Fifth term - fourth term = 47-30=17

So the AP is 5 9 13 17

We find out that the common difference is 9-5 = 4

The formula for nth term of the AP is

= a + nd

So the formula fir the sequence is

Second term =first term + (a+nd)

Third term = second term + (a+nd)

And so on

Where n start with zero

Plz help!!! Calvin is filling the pool in his backyard with water. If the pool is in the shape of a cylinder with a diameter of 12ft and a height of 5 ft, how much water is needed to fill a 3/4 of the pool?

Answers

Answer:

424.1175

Step-by-step explanation:

Volume of the total pool = π[tex]r^{2}[/tex]h

                                        = π x [tex]6^{2}[/tex] x 5

                                        = 565.49

needed to fill a 3/4 of the pool = [tex]\frac{3}{4}[/tex] x 565.49

                                                   = 424.1175

Considering the volume of a cylinder, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

Definition of volume

Volume is a measure of the space occupied by an object in three-dimensional space, using cubic units to measure it. The volume formula depends on the shape of the figure and its different dimensions.

Volume can be considered as the capacity of a container to hold a quantity of fluid (gas or liquid).

Volume of a cylinder

In the case of a cylinder, it is characterized by having two circular bases and a surface that joins the two bases. So the volume of a cylinder is π×r²×h.

Amount of water needed

In first place, you must know that the length of the radius is half the length of the diameter.

On the other side, it is needed to fill a 3/4 of the pool.

Then, considering the definition of volume and the expression of volume of a cylinder, the amount of water needed is calculated as:

amount of water=(3/4)×π×(12 ft ÷2)²× 5 ft

Solving:

amount of water=(3/4)×π×(6 ft)²× 5 ft

amount of water= 135π ft³

Finally, the amount of water needed to fill a 3/4 of the pool is 135π ft³.

What is the solution to a linear equation?

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here,  the expression as 4/5 (20x+5)=16x-2

                                                   80x+20 = 80x-10

Complete question

Nguyen is decorating the room for her sister's baby shower party. She is wrapping

Vietnamese conical hats in baby prints tissue paper to decorate the tables and some

shelves in the wall. Each hat has a diameter of 16 inches and a height of 9 inches. If

she wants to wrap 21 Vietnamese hats, how much tissue paper will she need?

A) 4,176 in²

B) 8,975 in²

C) 10,580 in²

D) 36,267 in²

Answer:

C) 10,580 in²

Step-by-step explanation:

The question above is solved by finding the Total Surface area of the the conical hats.

We are given the following values for each hats

Diameter of 16 inches , radius of the hat = Diameter ÷ 2 = 16 ÷ 2 = 8 inches

Height of 9 inches.

The formula for the Total Surface Area of a cone = πr[ r + √(h² + r²)]

= π × 8 [ 8 + √(9² + 8²)]

= 503.7 square inches or 503.7 in²

So, for one hat she would be needing 503.7 square inches or 503.7 in² of Vietnamese tissues.

We are told in the question that she wants to wrap 21 conical hats. Hence,

If 1 conical hats is wrapped with 503.7 in² of Vietnamese tissues.

21 conical hats =

21 × 503.7 in² = 10,577.7 in²

Approximately = 10,580 in²

Therefore, to wrap 21 Vietnamese hats, Nguyen would need 10,580 in² of tissue paper.
