261,256,251 find the 50th term
Answer:
[tex]a_{50}=16[/tex]
Step-by-step explanation:
Given that,
An airthmetic sequence,
261,256,251
We need to find the 50th term.
We have,
first term, a = 261
common difference = 256-261 = -5
The nth term of the AP is given by :
[tex]a_n=a+(n-1)d\\\\a_{50}=a+49d\\\\a_{50}=261+49(-5)\\\\a_{50}=16[/tex]
So, the 50th term of the sequence is 16.
Answer:
16

How many oxygen atoms are on the reactant side of this chemical equation?
2K3PO4(aq)+3Pb(NO3)2(aq)→6KNO3(aq)+Pb3(PO4)2(s)
Answer:
The number of oxygen atoms on the reactant side of the equation is 26.
Step-by-step explanation:
The equation is:
2K₃PO₄(aq) + 3Pb(NO₃)₂(aq) → 6KNO₃(aq) + Pb₃(PO₄)₂(s)
We can see that the reaction is balanced, that is to say, the number of atoms of the reactants is equal to the number of atoms of the products.
Now, we can count the number of oxygen atoms on the reactant side by multiplying the coefficients of K₃PO₄ and Pb(NO₃)₂ by the number of oxygen atoms as follows:
[tex] O_{r} = 2*4 + 3*(3*2) = 26 [/tex]
This is equal to the number of oxygen atoms of the products side:
[tex] O_{p} = 6*3 + 1*(4*2) = 26 [/tex]
Therefore, the number of oxygen atoms on the reactant side of the equation is 26.
I hope it helps you!

Help please explain quick!
Answer:
Yes
Step-by-step explanation:
[tex]3\frac{1}{6}[/tex] + [tex]5\frac{7}{8}[/tex]
When adding two fractions, both denominators must be the same
To do this, multiply [tex]3\frac{1}{6}[/tex] by 4 to make it into [tex]3\frac{4}{24}[/tex]
And multiply [tex]5\frac{7}{8}[/tex] by 3 to turn it into [tex]5\frac{21}{24}[/tex]
The new equation is:
[tex]3\frac{4}{24}[/tex] + [tex]5\frac{21}{24}[/tex] = 8[tex]\frac{25}{24}[/tex]
Since you can make a whole number from [tex]\frac{25}{24}[/tex], the number 8 becomes a 9
and the new answers becomes [tex]9\frac{1}{24}[/tex]

Soil sells for 8 1/4 cents per pound. how much would you save if you bought a 100 pound sack for $7.45?
The amount saved is $0.80 or 80 cents.
Since Soil sells for 8 1/4 cents per pound, the coat for 100 pound sack will be:
= 8 1/4cents × 100
= 8.25 cents × 100
= 825 cents
Since 100 cents = $1
825 cents = 825/100
825 cents = $8.25
Since the 100 pound sack was bought for $7.45, the amount saved will be:
= $8.25 - $7.45
= $0.80
