Answer:
The answer is
<h2>21.45 g/cm³</h2>
Step-by-step explanation:
The density of a substance can be found by using the formula
From the question
mass of platinum = 214.5 g
volume = 10 cm³
It's density is
We have the final answer as
<h3>21.45 g/cm³</h3>
Hope this helps you
Let's divide this question into two parts:
1. Choosing any 3 digit number.
2. Find the number that is 10 more.
1. Let choose the number 111. As you can see it is the three digit number.
2. Now to find the 10 more to 111, we have to add 10 to 111 as follows:
111
+10
--------
121
Hence, the 10 more to the number 111 is 121.
Answer:
c. x=3
Step-by-step explanation:
4^x = 8^(x − 1)
4 = 2^2
8 = 2^3
2^2^x = 2^3^(x-1)
We know that a^b^c = a^(b*c)
2^(2x) = 2^(3*(x-1))
2^(2x) = 2^(3x-3)
The bases are the same so the exponents are the same
2x = 3x-3
Subtract 3x from each side
2x-3x = 3x-3-3x
-x = -3
x =3
Answer:
$1530 = 45% commission
Step-by-step explanation:
First, jot down the important facts:
• first $1000 = 10% comm.
• next $2000 = 15% comm.
• total more than $3000 = 20% comm.
• total comm. = $3400
Then, go in order with your jotted facts to withdraw the total commission amount. Here's what I mean:
$3400 ← total is more than $3000 = +20% comm.
<u>- $1000</u> ← the first $1000 = +10% comm.
$2400
<u>- $2000</u> ← the next $2000 = +15% comm.
$400
Then, add together the commission percentages:
20% + 10% + 15% = 45% comm.
Convert the percentage to a decimal:
45% × 100 = 0.45
And multiply it with the total amount to find the commission amount:
$3400 × 0.45 = $1530
It should be 40 percent.
You can think of it as starting with 100 as in 100 dollars or 100 tic tacs
If you take away 25%, you take away 25 tic tacs and now you only have 75.
From your 75, you take away 20% which is equal to 15. 75- 15=60
If you look at the end result of 60, you can see that that is 100 - 40 so 40% of the total was taken off
