A sample of gold has a mass of 579 g. The volume of the sample is 30 cm3. What is the density of the gold sample?

Answer:

5/8

Step-by-step explanation:

Since we don't know what the other color (s) are, all we need to do to determine the probability is add the two fractions, and that is your probability.

Answer:

5/8

Step-by-step explanation:

The probability of a red block shows 3/8.  This means there are 8 blocks total and only 3 of them are red.

The probability of a blue block shows 2/8.  Again there are 8 total blocks and only 2 are blue.

So the total number of blocks remains the same....8

The total of red and blue blocks is 3 + 2 = 5

So the probability would be 5/8

Given the image attached, the segment bisector that divides XY into two and the length of XY are as follows:

Recall:

In the diagram attached below, line n divides XY into XM and MY.

Thus, the segment bisector of XY is: line n.

Find the value of x:

XM = MY (congruent segments)

[tex]5x + 8 = 9x + 12[/tex]

[tex]5x + 8 = 9x + 12\\5x - 9x = -8 + 12\\\\-4x = 4\\\\x = -1[/tex]

XY = XM + MY

[tex]XY = 5x + 8 + 9x + 12[/tex]

[tex]XY = 5(-1) + 8 + 9(-1) + 12\\\\XY = -5 + 8 -9 + 12\\\\\mathbf{XY = 6}[/tex]

Therefore, given the image attached, the segment bisector that divides XY into two and the length of XY are as follows:

Answer:

Step-by-step explanation:

convert both mixed fractions to improper fractions first

2 1/3 = 7/3    3 1/4 = 13/4

(cross multiplication method, to make both fractions have the same denominator)

7/3 + 13/4

7/3 × 4/4 = 28/12

13/4 × 3/3 = 39/12

28/12 + 39/12 = 67/12 (just add, denominator will remain the same)

67/12 (simplify)

67/12 = 5 7/12 (simplified)

The amount added to the original price of the jewelery is the Markup price. Hence, the amount added is $16.34

Retail price = cost of jewellery + Markup

$45 = c + 0.57c

45 = 1.57c

Divide both sides by 1.57

c = 45/1.57

c = $28.66

The Markup price = (Retail price - Original price)

Therefore, the amount added to the original price is $16.34

Answer:

I beleive X=2

Area is 24

Step-by-step explanation:

X=2 because the side with B has 4cm and on the other it has 6 but the 4 can be put into 6 and 6-4 is 2 if that made any sense

The area is 4 times 2= 8 and then 8 times 2 is 16

Charlene's age with x+8

x+x+8=44

2x+8=44

2x=44-8

2x=36

x=36÷2

x=18

Aaron is 18 years old.

While Charlene is 18+8=26 years old.

Answer:

Step-by-step explanation:

x + 0.05x = 36225

x(1 + 0.05) = 36225

x*1.05 = 36225

by solving we find:

x = $34,500

Answer:

x = 7

Step-by-step explanation:

To solve:

Distribute 5 among everything inside the first parentheses. You'll get 5x - 15.

Next distribute -2 among everything in the second parentheses. You'll get

-2x - 2.

All together: 5x - 15 -2x - 2 = 4

Now combine like terms:

5x - 2x = 3x and -15 - 2 = - 17

All together: 3x - 17 = 4

Add 17 on both sides to get 21, and then divide both sides by 3. Answer is x = 7.

________________________________

Last, don't forget to check your work.

You can plug in 7 for x to get:

5(7 - 3) = 20

5 × 7 = 35

5 × -3 = -15

35 - 15 = 20

-2(7 + 1) = -16

-2 × 7 = -14

-2 × 1 = - 2

-14 -2 = -16

20 - 16 = 4

⬆⬆⬆Therefore this is correct.
