(2.5 x 10^6) + (1.2 x 10^3)
whats the answer to this???
Hey
[tex]\text{there}[/tex]
[tex](2.5 \times {10}^{6}) + (1.2 \times{10}^{3}) [/tex]
[tex] {10}^{6}=1000000[/tex]
[tex](2.5\times1000000) + (1.2\times{10}^{3})[/tex]
[tex] {10}^{3} = 1000[/tex]
[tex](2.5 \times 1000000) + (1.2 + 1000)[/tex]
[tex](2.5\times1000000) = 2,500,000[/tex]
[tex](2,500,000) + (1.2 \times 1000)[/tex]
[tex](1.2\times1000)=1,200[/tex]
[tex](2,500,000)+(1,200)=2,501,200[/tex]

Using reasoning, determine the number of marbles that you would expect to fit if you doubled the diameter
Original diameter was 8cm, could fit 40 marbles. New diameter is 16cm. How many marbles would I fit?
Answer:
80 marbles
Step-by-step explanation:
8 times 2=16
40 times 2=80
Solve 8x - 2(x + 1) = 7x + 8.
The answer is
X = -10

7 apples cost $2.10. How many apples can I buy for $6.30
Answer:
21
Step-by-step explanation
If 7 apples are 2.10 then for 4.20 its 14 apples. And 3 apples is 90 cents. 1 apple is 0.30. So the amount you can buy is 21 because 6.30/0.3 is 21
Answer:
21
Explanation:
If 7 apples cost y cents, how many can you buy for x dollars?
As y cents buy 7 apples, y dollars will buy 7×100 apples.
Hence one dollar will buy 7×100y=700y apples and,
x dollars will buy 700y × x apples or 700x y apples.
Hence 7 apples multiplied by $6.30 divided by $2.10 will get you 21 apples.

you want 75,000 in your savings account 12 years from now and you are prepared to make equal annaul deposits into the account at the end of the year. if the account pays 6.8 percent interest, what amount must you deposit each year
Answer:
Annual deposit= $3,474.39
Explanation:
Giving the following information:
You want to have $60,000 in your savings account 12 years from now, and you’re prepared to make equal annual deposits into the account at the end of each year. The account pays 6.4 percent interest.
FV= {A*[(1+i)^n-1]}/i
A= annual deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (60,000*0.064)/[(1.064^12)-1]= $3,474.39

3(x−2)+5x=26 (What property is this?)
3x−6+5x=26 (What property is this?)
8x−6=26 (What property is this?)
8x=32 (What property is this?)
x=4 (What property is this?)
Here are a list of the properties-
Subtraction Property of Equality
Addition Property of Equality
Multiplication Property of Equality
Division Property of Equality
Combine Like Terms
Distributive Property
Given Equation
Answer:
[tex]3(x-2)+5x=26[/tex] (Given Equation)
[tex]3x-6+5x=26[/tex] (Distributive Property)
[tex]8x-6=26[/tex] (Combine Like Terms)
[tex]8x=32[/tex] (Addition Property of Equality)
[tex]x=4[/tex] (Division Property of Equality)
Step-by-step explanation:
To justify the solution paths of linear equations.
[tex]3(x-2)+5x=26[/tex] (It is the Given Equation)
Here, 3 has to be multiplied with the term [tex](x-2)[/tex], so the distributive property applies.
Therefore, [tex]3x-6+5x=26[/tex]
Here, the like terms with [tex]x[/tex] in it will have to solved by combining them into one.
Therefore, [tex]8x-6=26[/tex]
Here, we add 6 to both sides.
[tex]8x=32[/tex]
Now, divide the both sides with 8.
[tex]x=4[/tex]
Therefore, the answer is:
[tex]3(x-2)+5x=26[/tex] (Given Equation)
[tex]3x-6+5x=26[/tex] (Distributive Property)
[tex]8x-6=26[/tex] (Combine Like Terms)
[tex]8x=32[/tex] (Addition Property of Equality)
[tex]x=4[/tex] (Division Property of Equality)

Calculate the present value PV of an investment that will be worth $1,000 at the stated interest rate after the stated amount of time. 7 years, at 3% per year, compounded annually.
Answer:
PV= $813.09
Step-by-step explanation:
Giving the following information:
Future Value (FV)= $1,000
Number of periods (n)= 7 years
Interest rate (i)= 3% compounded annually
To calculate the present value (PV), we need to use the following formula:
PV= FV/(1+i)^n
PV= 1,000 / (1.03^7)
PV= $813.09

Kayla drives 144 miles in 3 hrs. Kendra drives 224 miles in 4 hours. How much faster does Kendra drive on an average?
Answer:
12 miles per hour more
Step-by-step explanation:
Answer:
Kendra drives 8 hours more on average.
Step-by-step explanation:
We divide 144/3 to get Kayla's mile to hour.
That is 48 miles.
We divide 224/4 to get Kendra's mile to hour.
That is 56 miles.
56 - 48 = 8.
hope this helped!
