Answer:
131.25 gram is gold
Step-by-step explanation:
Rock = 525 gram
Gold = 25.0% of the rock
To determine how many grams of the rock are gold,
Find 25.0% of 525 gram
= 25/100 × 525
= 0.25 × 525
= 131.25 gram
Gold = 131.25 gram of the rock
Therefore,
131.25 gram of the rock is gold
What is the 8th term of this geometric sequence?
1, 3, 9, 27,...
Answer:
1*3*3*3*3*3*3=729. For each term you multiply the previous term by three.
Answer:
2187
Step-by-step explanation:
To find the 8th term, we can find and use the explicit formula.
The standard form of the explicit formula for a geometric sequence is:
[tex]x_n=a(r)^{n-1}[/tex]
Where a is the initial term, r is the common ratio, and n is the nth term.
From the sequence, we can see that the first term is 1, and each term is 3 times the previous term. Thus, the common ratio is 3.
Substituting these into our equation, we will have:
[tex]x_n=1(3)^{n-1}\\x_n=(3)^{n-1}[/tex]
So, to find the 8th term, substitute 8 for n:
[tex]x_8=(3)^{8-1}[/tex]
Subtract:
[tex]x_8=(3)^7[/tex]
Evaluate:
[tex]x_8=2187[/tex]
So, the 8th term is 2187.
And we're done!

In our first step, we will need to simplify the inequality.
[tex]2x+16>x+14[/tex]
Now we have to subtract x from both sides of the inequality.
[tex]2x+16-x>x+14-x=x+16>14\\x+16>14[/tex]
In our last step, we will need to subtract 16 from both sides of the inequality.
[tex]x+16-16>14-16=x>-2\\x>-2\text{(ANSWER)}[/tex]

Step-by-step explanation:
Dr. Watson received a $15 gift card to download music for her mp3 player. Each Song costs $1.50. Find the equation that represents the
remaining balance on the gift card after x downloads. What is a suitable domain for this function?
Answer:
y = -1.50x + 15, Domain is from 0 to 10
Step-by-step explanation:
First, look at the question carefully and highlight all the words that are important. We know that the 15 dollar giftcard is important, and we know that each song costs 1 dollar and 50 cents is important. We will make an equation out of this information. Since she is spending money, the value of X will be negated. She starts out with 15 dollars, so that will be our y-intercept. From this, the equation is y = -1.50x + 15. Next, let's look at the domain. We can see that the question asks for a suitable domain, not the domain of the function. Since she didn't have more than 15 dollars from her gift card, any domain from negative infinity until 0 will be crossed out. The x-intercept of this equation is 10, so any value above 10 will be crossed out since you cannot spend more money than you were given. The domain would now be from 1 to 10.

It's looking for the solved answer, not the simplified expression (no variable in final answer)
Answer:
BC = 144 units
Step-by-step explanation:
BC = BD + DC , substitute values
8x = 4x + 10 + 3x + 8 = 7x + 18 ( subtract 7x from both sides )
x = 18
Thus
BC = 8x = 8 × 18 = 144 units

Adrian creates some paintings every month. The numbers below show how many paintings Adrian has completed each month for the last year. What is the median of the set of data? 4, 5, 2, 1, 0, 3, 2, 4, 3, 2, 7, 5 *
Given :
Number of paintings Adrian created each month for the last year are :
4, 5, 2, 1, 0, 3, 2, 4, 3, 2, 7, 5 .
To Find :
The median of the set of data .
Solution :
To find the median we should arrange the numbers in ascending order .
So , 0, 1, 2, 2, 2, 3, 3, 4, 4, 5, 5, 7 .
Now , median for odd is the middle term but for even numbers it is the average of middle two terms .
So ,
[tex]Median =\dfrac{3+3}{2}\\\\Median =3[/tex]
Therefore , the median of the set of data is 3 .
Hence , this is the required solution .

6) Marcy gave Juanita as many dimes as Juanita had. Then Juanita gave Marcy as many dimes as Marcy had left. Juanita now had 26 dimes and Marcy had 20 dimes. Originally, Marcy had( )dimes.
Answer:
0
Step-by-step explanation:
The original amount of dimes Marcy had before sharing with Jaunita is 52.
What is the solution to the word problem about dimes?Let's break down the given information step by step to determine the original number of dimes Marcy had.
Marcy gave Juanita as many dimes as Juanita had.
After this transaction, Juanita now has 26 dimes, and Marcy has x - 26 dimes, where x is the original number of dimes Marcy had.
Juanita gave Marcy as many dimes as Marcy had left.
After this transaction, Marcy now has 20 dimes, and Juanita has 26 - 20 = 6 dimes remaining.
From the above information, we can set up the following equation:
x - 26 = 20 + 6
Simplifying the equation:
x - 26 = 26
Adding 26 to both sides:
x = 52
Therefore, the original amount of dimes Marcy had is 52 dimes.

The diameter of the circle is 6 miles. What is the area of the circle? Use 3.14 for II.
Answer:
28.26 miles
Step-by-step explanation:
Area= pi times radius squared
diameter is twice the radius so 6÷2=3miles
3 miles is the radius
So A= 3.14 × 3²
= 28.26
Formula: A = πr²
Divide to find the radius.
6 / 2 = 3
Solve using the values we are given and solved for.
A = π(3)²
A = 9π
A ≈ 28.26
