How to solve [tex]2n =\frac{15}{2}[/tex] and [tex]\frac{1}{4} =\frac{n}{5}[/tex] ???

Answers

Answer 1

Answer:

[tex]2n=\dfrac{15}{2}[/tex]

Multiply both sides by 2:

[tex]\implies 2 \cdot 2n=2 \cdot \dfrac{15}{2}[/tex]

[tex]\implies 4n=15[/tex]

Divide both sides by 4:

[tex]\implies \dfrac{4n}{4}=\dfrac{15}{4}[/tex]

[tex]\implies n=\dfrac{15}{4}[/tex]

[tex]\dfrac14=\dfrac{n}{5}[/tex]

Multiply both sides by 5:

[tex]\implies 5 \cdot \dfrac14=5 \cdot \dfrac{n}{5}[/tex]

[tex]\implies \dfrac54=n[/tex]

[tex]\implies n=\dfrac54[/tex]

Answer 2

Answer:

Step-by-step explanation:

2n = 15/2

Divide both sides b y 2:

n = 15/2 / 2

   = 15/2 * 1/2

    = 15/4.

1/4 = n / 5

Multiply both sides by the LCM (20):

20/4 = 20n/5

5 = 4n

n = 5/4.

19x+28=20x-53

Answers

Answer:

x = 81

Step-by-step explanation:

Given:

[tex]\displaystyle \large{19x+28=20x-53}[/tex]

Subtract both sides by 28:

[tex]\displaystyle \large{19x+28-28=20x-53-28}\\\displaystyle \large{19x=20x-81}[/tex]

Subtract both sides by 19x:

[tex]\displaystyle \large{19x-19x=20x-81-19x}\\\displaystyle \large{0=x-81}[/tex]

Add both sides by 81:

[tex]\displaystyle \large{0+81=x-81+81}\\\displaystyle \large{81=x}\\\displaystyle \large{\therefore x=81}[/tex]

Therefore, the solution is x = 81

Answers

Answer: Below

Step-by-step explanation:

Volume is based off of the formula (base × height/depth), with base being (width × length).

We know the three dimensions of the taller box, so:

7.75 × 2 × 12 = 186

The smaller box is 20% shorter. 12 × 0.8 gives us the 0% height, which is 9.6.

7.75 × 2 × 9.6 = 148.8

Since the problem is asking for the difference of the two volumes we do:

186 - 146.8 = 39.2

Our answer is 39.2

A grain silo has a cylindrical shape. Its radius is 8ft, and its height is 36ft. What is the volume of the silo?

Use the value 3.14 for[tex]\pi[/tex], and round your answer to the nearest whole number.
Be sure to include the correct unit in your answer.

Answers

The volume of a silo cylinder with radius of 8 feet and height of 36 feet is 7235 feet cube.

Volume of a cylinder

The volume of a cylinder can be calculated as follows;

Volume = πr²h

where

r = radiush = height

Therefore,

r = 8 ft

h = 36 ft

volume = 3.14 × 8² × 36

volume = 3.14 × 64 × 36

volume of the silo = 7234.56

Therefore, the volume of the cylindrical silo is 7235 ft³

need it ASAP If a graph shows intersecting lines that represent a system of equations, how many solutions does that system of equations have?
Infinite solutions
No solution
Two solutions
One solution

Answers

Answer: Well, the answer really depends. But here are a few ways you can figure this out.

Step-by-step explanation:

If the two lines intersect once, then they have one solution.

If they intersect twice there are two solutions

If the lines never intersect, there are no solutions

And if the lines are identical, meaning that their equation is exactly the same. There are infinite solutions.

A solution with systems of equations is determined by the point of intersection. Your answer is the point of intersection

Vertical angles are congruent angles that lie directly opposite each other.

Second Row:

m∠LGK = 45° (given in the diagram)

m∠IGH = 35° (given in the table)

m∠KGJ = m∠IGH (vertical angles)

m∠KGJ = 35°

m∠JGI = 180 - m∠KGJ (angles on a straight line)

m∠JGI = 180 - 35 = 145°

m∠HGL = 180 - m∠LGK - m∠IGH (angles on a straight line)

m∠HGL = 180 - 45 - 35 = 100°

Third Row:

m∠LGK = 45° (given in the diagram)

m∠HGL = 97° (given in the table)

m∠KGJ = 180 - m∠HGL - m∠LGK (angles on a straight line)

m∠KGL= 180 - 97 - 45 = 38°

m∠JGI = 180 - m∠KGJ (angles on a straight line)

m∠JGI = 180 - 38 = 142°

m∠IGH = m∠KGL (vertical angles)

m∠IGH = 38°
