Give value to four significant figures.
Answer:
very specific...sus...yea no one knows
Step-by-step explanation:
In order to determine the mass of one atom of an element, you must determine its molar mass, which is its atomic weight on the periodic table in g/mol, and you need to know the relationship between moles and the number of atoms: 1 mol of atoms = 6.022×1023 atoms . Then divide the molar mass by 6.022×1023 atoms/mol .

3+2x = 41
Need help
Show work
Answer:
x=16
Step-by-step explanation:
when solving for a variable, get the variables to one side of the equation and the numbers to the other side.
3+2x=41
*minus 3 from both sides of the equation to get rid of the number on the side of variables of the equation*
2x=38
to get one variable alone, divide the whole equation by 2
x=16

Please someone help answer correctly !!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!
Answer:
z = 44
Step-by-step explanation:
180 - (44+52) = 180 - 96 = 84º
180 - 84 = 96º
180 - (96 + 40) = z
180 - 136 = z
z = 44

Step-by-step explanation:
Solve the equation 3 (p-1) = 2p – 11.
Answer:
p = - 8
Step-by-step explanation:
3 (p - 1) = 2p - 11
3p - 3 = 2p - 11
3p - 2p = -11 + 3
p = -8
Answer:
p = - 8
Step-by-step explanation:
Given
3(p - 1) = 2p - 11 ← distribute parenthesis on left side
3p - 3 = 2p - 11 ( subtract 2p from both sides )
p - 3 = - 11 ( add 3 to both sides )
p = - 8

2. Solve x - 19 <81. Then graph the solution.
Answer:
x<100
Step-by-step explanation:
The given equation is :
x-19<81
Adding 19 to both sides of the equation.
x-19+19<81+19
x<100
It means the solution of the given equation is less than 100. Hence, the attached figure shows the graph for the given equation.
My point exactly in algebra.
Select the correct answer.
Simplify the expression
Answer: A
Step-by-step explanation:
Since multiplication is the only operation under the radical, you can apply the root to each term. Im not sure if I worded that correctly, but ill hopefully explain correctly.
First we need to take the cubed root of 648. This number doesn't have a perfect root, but it can be simplified. 648 is the same as 216*3, and 216 has a perfect cubed root of 6. So we can bring the 6 outside of the radical
[tex]3x*6\sqrt[3]{3x^4y^8}=18x\sqrt[3]{3x^4y^8}[/tex]
The next step is simplifying the variables, which is the easiest part. Just split them up into multiples of 3, again poor explanation but Ill show what I mean.
[tex]18x\sqrt[3]{3x^3xy^3y^3y^2}[/tex]
The cubed root and the cubed power will cancel and can be brought outside the radical[tex]18x*xy^2\sqrt[3]{2xy^2} =18x^2y^2\sqrt[3]{3xy^2}[/tex]

Here u go Hanifa :D <----------
Answer:
B. 2200 ft²Step-by-step explanation:
To find the area, calculate two parts and add up
The triangle section has sides:
40 ft and 50 - 30 = 20 ftThe area:
1/2*20*40 = 400 ft²The rectangle section has sides:
30 ft and 20 + 40 = 60 ftThe area:
30*60 = 1800 ft²Total area:
400 + 1800 = 2200 ft²Correct option is B
what is 3(x - 4)= 12x
Answer:
x = 4/5
Step-by-step explanation:
3(x-4)=12x
3x-12=12x
3x+12x-12=12x-12x
15x-12=0
15x-12+12=0+12
15x=12
15x/15=12/15
x = 4/5

A savings account earns 4.5% simple interest per year. If $650 is deposited and no withdrawals are made during one year, how much interest will be earned after one year?
Answer:
$29.25
Step-by-step explanation:
The formula for amount of interest is the P*R*T. Because the principal is $650 dollars, and the rate is 4.5% for 1 year, the formula so far is 650*0.045*T. The interest is per annum or annual, so the time has to be in terms of years, which in this case is 1 year. This would give you 650*0.045. The answer for that is simply $29.25.
