simplify by prime factorization 15/27

Answers

[tex]⟹ \: \cancel \frac{15}{27} = (3 \times 3 \times 3 \times 3 \times 3 ) \: (9 \times 9 \times 9)[/tex]

[tex] ⟹ \cancel \frac{15}{27} = 5(3) \times 9(3)[/tex]

[tex]⟹ \cancel \frac{15}{27} = \frac{5}{9} [/tex]

Therefore, when 15/27 is factorise using the method of prime factorization we'll get 5/9.

Which quadrant will be completely shaded by the graph of the inequality y < 3x ?
A.Quadrant I
B. Quadrant II
С. Quadrant III
D. Quadrant IV

Answers

Answer:

D. Quadrant IV

Step-by-step explanation:

At first we need to graph the function [tex]y = 3\cdot x[/tex], whose representation is included in the figure attached below. The positive slope and the y-intercept equal to zero means that the inequality only takes any point below the line into account, that is, it covers Quadrants I and III partially and the Quadrant IV completely. Then, the correct answer is D.

Joey has two pieces of wood. One is 120 inches and the other one is 210 inches long. He wants to cut both the pieces into smaller parts so that all these parts are of the same length.
i) If he wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?
Ans:
ii) How many smaller pieces of wood will he have in total?
Ans:

Answers

Answer:

A. 30 inches

B. 11 pieces

Step-by-step explanation:

Piece 1 = 120 inches

Piece 2 = 210 inches

1. He wants the smallest pieces to be as long as possible without having any leftover, how long should each piece be?

Find the highest common factor of 120 and 210

120: 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, and 120.

210: 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210.

The highest common factor of 120 and 210 = 30

Therefore, the smallest and longest pieces should be cut into 30 inches each

B. Total Smaller pieces of wood = piece 1 / 30 + piece 2 / 30

= 120/30 + 210/30

= 4 + 7

= 11 pieces

Answers

Answer:

x = 1

y = 10

Step-by-step explanation:

5x + y = 15

Step 1: Move 5x on the other side by subtracting it from both sides

y = 15 - 5x

2x + y = 12

Step 2: Move 2x on the other side by subtracting it from both sides

y = 12 - 2x

Since y = y, that means 15 - 5x = 12 - 2x

Step 3: Add 5x to both sides

15 = 12 + 3x

Step 4: Subtract 12 from both sides

3 = 3x

Step 5: Divide both sides by 3

x = 1

y = 12 - 2x

Step 6: Plug in 1 for x

y = 12 - 2(1)

Step 7: Multiply 2 by 1

y = 12 - 2

Step 8: Subtract 2 from 12

y = 10

Which interval is the solution set to 0.35x-4.8<5.2-0.9x?

Answers

I Inequality form: x<8

Interval Notation: (-infinity,8)

Answer:

B. (–∞, 8)

Step-by-step explanation:

Simplifying

0.35x + -4.8 < 5.2 + -0.9x

Reorder the terms:

-4.8 + 0.35x < 5.2 + -0.9x

Solving

-4.8 + 0.35x < 5.2 + -0.9x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '0.9x' to each side of the equation.

-4.8 + 0.35x + 0.9x < 5.2 + -0.9x + 0.9x

Combine like terms: 0.35x + 0.9x < 1.25x

-4.8 + 1.25x < 5.2 + -0.9x + 0.9x

Combine like terms: -0.9x + 0.9x < 0.0

-4.8 + 1.25x < 5.2 + 0.0

-4.8 + 1.25x < 5.2

Add '4.8' to each side of the equation.

-4.8 + 4.8 + 1.25x < 5.2 + 4.8

Combine like terms: -4.8 + 4.8 < 0.0

0.0 + 1.25x < 5.2 + 4.8

1.25x < 5.2 + 4.8

Combine like terms: 5.2 + 4.8 < 10

1.25x < 10

Divide each side by '1.25'.

x < 8

How can we express numbers belonging to decimal numeral system?

Suppose that the number is abcd.efg and belongs to the decimal numerical system.

Remember one thing that the place on the left of decimal point is called ones. Move one-one places to right, and divide by 10 and 10 more and more.

Move one-one places to left, and multiply (un-divide) by 10 and 10 more and more.

Thus, we write abcd.efg as:

[tex]a \times 10^3 + b \times 10^2 + c \times 10^1 + d \times 10^{0} + e \times 10^{-1} + f \times 10^{-2} + g \times 10^{-3}[/tex]

We will call d as ones digit, c as tens digit (it get multiplied by 10), b as hundreds digit etc.

We call e as digit at 10th place (division by 10), f as digit at hundredth place and so on.

Given;

Two decimal numbers;  2.7 and 2.8

Mid point=a+b/2

=2.7+2.8/2

=5.5/2

=2.75

Therefore, the mid value in decimal will be 2.75

BC MY OTHER ACC GOT FALSE BANNEDRead the Greek myth "Midas" retold by Thomas Bulfinch and answer the question.[1] Bacchus, on a certain occasion, found his old schoolmaster and foster-father, Silenus, missing. The old man had been drinking, and in that state wandered away, and was found by some peasants, who carried him to their king, Midas. Midas recognized him, and treated him hospitably, entertaining him for ten days and nights with an unceasing round of jollity.[2] On the eleventh day he brought Silenus back, and restored him in safety to his pupil. Whereupon Bacchus offered Midas his choice of a reward, whatever he might wish. He asked that whatever he might touch should be changed into gold. Bacchus consented, though sorry that he had not made a better choice.[3] Midas went his way, rejoicing in his new-acquired power, which he hastened to put to the test. He could scarce believe his eyes when he found a twig of an oak, which he plucked from the branch, become gold in his hand. He took up a stone; it changed to gold. He touched a sod; it did the same. He took up an apple from the tree; you would have thought he had robbed the garden of the Hesperides. His joy knew no bounds, and as soon as he got home, he ordered the servants to set a splendid repast on the table. Then he found to his dismay that whether he touched bread, it hardened in his hand; or put a morsel to his lip, it defied his teeth. He took a glass of wine, but it flowed down his throat like melted gold.[4] In consternation at the unprecedented affliction, he strove to divest himself of his power; he hated the gift he had lately coveted. But all in vain; starvation seemed to await him. He raised his arms, all shining with gold, in prayer to Bacchus, begging to be delivered from his glittering destruction. Bacchus, merciful deity, heard and consented. "Go," said he, "to River Pactolus, trace its fountain-head, there plunge yourself and body in, and wash away your fault and its punishment." He did so, and scarce had he touched the waters before the gold-creating power passed into them, and the river sands became changed into gold, as they remain to this day.Select two key details that could be included in a summary of the myth. Bacchus granted Midas's wish for a golden touch. Midas couldn't eat because of the wish Bacchus granted. Midas entertained Silenus in his kingdom for ten days. Midas recognized Silenus as Bacchus's teacher. Silenus was found by peasants and carried to Midas. 3.
