The speed of sound is about 3.4 x 10^2 meters per second. Mark is performing a science experiment and he needs to know how far sound travels in
3 x 10^10 seconds. If mark uses a calculator to solve his problem, how will the calculator show his answer?

Answer:

40

Step-by-step explanation:

there are 9 cow for ever 8 horses

45 is 5 sets of 9 (45/5 = 9)

so to make this ratio equal you have to multiply the amount of horses by 5 too

8*5=40

40 horses

Answer:

a

Step-by-step explanation:

divide the cost by the number of goldfish

rewrite 6.00 as 600 and divide by 20 to get 30

then add the decimals back to get 0.30

Answer:

3.95m + 8.95b = 47.65

Step-by-step explanation:

Since Hugh paid $3.95 for every magazine, m would be multiplied by 3.95

Since he also paid $8.95 for every book, b would be multiplied by 8.95

All of this will eventually add up to a sum of 47.65

Answer:

52 square feet.

Step-by-step explanation:

length*width=area

Top rectangle = 4ft*5ft = 20sq.ft

Bottom rectangle = 4ft*8ft = 32sq. ft

20+32=52 sq.ft OR (4*5)+(4*8)=52sq.ft

Answer:

It equals to 16.

4(2)*2 - 2(2) + 4

4(4) - 4 + 4

16 - 0

= 16

The values of :

The given equations are :

now, let's multiply both the equations with 10 on both sides.

so, now our equations will be :

from Equation second :

now, let's substitute the value of y from here into Equation first.

here, we got the value of x = 2, let's plug it in equation second to find value of y :

And value of y = 3

Answer:

25 and 55

Step-by-step explanation:

Let's call the larger number L and the smaller S

L = 5 + 2×S

And the sum is:

L + S = 80 Subtract S in both sides:

L = 80 - S

Now, substitute this value of L in the first equation:

80 - S = 5 + 2×S Add S in both sides:

80 = 5 + 2×S + S

80 = 5 + 3S Subtract 5 in both sides

75 = 3S Divide both sides by 3

25 = S

We find the value of S, and now we substitute it in the second equation to find the value of L:

L = 80 - 25

L = 55

Step-by-step explanation:

10-(-2) = 10+2 = 12.

Hello there!

10-(-2)=10+2=12

Have a nice day! :-)

x= 0

f(0)= 2(0+2)+ 4(0)= 4

f(16)= 2(16+2)+ 4(16) = 100

f( 10) = 2(10+2) + 4(10)= 64

f(94)= 2( 94+ 2) + 4(94) = 568

Answer:

I am going to answer using calculus. Let me know if you instead were looking for an algebraic method. Take the definite integral from 3 to 6 of xdx. [x^2/2]3 to 6= 18-(9/2)= (36-9)/2= 27/2. The area is 27/2

Answer:

56

Step-by-step explanation:

First, copy the given expression. Then replace p with 4. Then evaluate the expression.

3p^2 + 8 =

= 3(4^2) + 8

= 3(16) + 8

= 48 + 8

= 56

Step-by-step explanation:

A = Future value of the amount invested

P = principal (amount of money invested) = $9,200

i  = interest rate =  6% or 0.06

n = number of compounding periods (it is the number of times the interest is compounded).

For the Interest Rate per Compounding Period column, you'll have to divide the interest rate by its corresponding compounding period (please see the definitions of each compounding periods below). For example, the interest rate per compounding period (compounded annually) = interest rate ÷ number of compounding periods ( [tex]\frac{i}{n}[/tex] ) = 0.06/1 = 0.06 or 6%

For the Number of Compounding Periods column, you'll have to multiply (t ) by the number of compounding periods (n):

t × n =  15 years × 1  =  15

The Compound Interest Formula column is pretty self-explanatory--you'll just have to follow the given formula. You need to make sure that you change the values for i and n  for every row.

Compounding periods (n):

compounding annually: n = 1  

compounding semiannually: n = 2

compounding quarterly: n = 4

compounding monthly: n = 12

compounding weekly: n = 52

compounding daily: n = 365

You'll have to use these values into your Compound Interest formula.

I will do the 2nd row (semi-annually) for you as a guide, but you'll have to do the rest so that you could familiarize yourself on how to do it.

Interest Rate per Compounding Period  = i / n = 0.06/2 = 0.03 or 3%

Number of Compounding Periods = t × n =  15 years × 2 = 30

Compound Interest Formula:  [tex]A = 9,200(1 + 0.03)^{30}[/tex]

Final Amount  = 22,330.81

Answer:

30 +x = 3(y-70)
