The mouth of a large river has a flow of fresh water, amounting to 5,500,000 cubic feet per second. How many cubic meters per second pour out of the mouth of this
river? (Use 1 foot 0.305 meter.)

Answer:

d =  y = 4.25x

correct answer i would say.

Step-by-step explanation:

Cheddar cheese cost 4.25 per pound . This means the cost of cheddar cheese is 4.25 for every pound in weight. Assuming we put a currency to the value we can say 1 pound of cheddar cheese is equals to 4.25 dollars($4.25). Mathematically, it can be represented as  

4.25 is the cost for 1 pound of Cheddar cheese

Let the cost of the equation be y as required from the question.

y = cost of the cheddar cheese

x is the weight value in pounds of the Cheddar cheese.

The equation can be best represented as

y = 4.25x

In the equation above if the amount in pounds is 3 pound . the value will be inputted for x and the cost will be gotten which is y.

Answer:

smaller number is 26

larger number is 28

Step-by-step explanation:

This is a system of equations that we can solve by substitution.  Let x = the smaller number and y the larger.  The two equations are:

x + y = 54

x + 5y = 166

Solve the first equation for y and use that in the second equation.

y = 54 - x (we will plug this in for y in the second equation and solve that for x)

x + 5(54 - x) = 166

x + 270 - 5x = 166

-4x = 166 - 270

-4x = -104

x = 26

Plug this into x + y = 54 and solve for y

26 + y = 54

y = 54 - 26

y = 28

Step-by-step explanation:

14b +21 -2b=0

12b +21=0

12b= -21

b= -21/12

b= - 7/4 or -1.75

Answer:

i dont know what you neccesarily want but here are two answers b=-7/4 or -1 3/4 other answer is 12b+21

Step-by-step explanation:

first, you have to set this question equal to 0.

7(2b+3)-2b=0

now you have to distribute the 7 to everything inside the parentheses.

14b+21-2b=0

combine like terms

12b+21=0

you can stop here and take this answer if this is the one you want

now subtract each side by 21

12b=-21

divide each side by 12

b=-21/12

simplify

b=-7/4

hope this helps! have a nice day :)

Step-by-step explanation:

To work out the height of the cuboid, we need to use the formula:

Volume = Length x Width x Height

We have been given the volume and the length, so we can substitute those values into the formula:

540 = 6 x Width x Height

Now we need to convert the width from millimeters to centimeters, so we divide it by 10:

150mm ÷ 10 = 15cm

Substituting this value into the formula:

540 = 6 x 15 x Height

Simplifying:

540 = 90 x Height

Dividing both sides by 90:

6 = Height

Therefore, the height of the cuboid is 6cm.

The average number of likes will be 16.5. the correct option is D.

Mean is defined as the ratio of the sum of the number of data sets to the total number of data. The mean is calculated by adding all the data points and dividing it by the total number of the data.

Given that Bethany has a photo website where she places photos that she has taken so others can see them. Below is how many likes each of her current photos was given: 10, 13, 15, 15, 17, 29.

The average will be calculated as:-

Mean = ( 10 + 13 + 15 + 15 + 17 + 29 ) / 6

Mean = 99 / 6

Mean = 16.5

Therefore, the average number of likes will be 16.5. the correct option is D.

Answer:

Option B : 38/2 is the correct answer.

Step-by-step explanation:

Given that:

Distance to travel = 38 miles

Speed of object = 2 miles per hour

Distance = Speed * Time

To find the time, we will divide the distance by speed.

Time = \(\frac{Distance}{Speed}\)

Putting values of distance and speed in the formula.

Time = 38/2

Marry put $1200 into a 3% interest paying account.

And she put 600 dollars in a 5% interest account.

Interest is computed as a percentage of the principal in its most basic form. For example, if you borrow $100 from a friend and agree to repay it with 5% interest, the amount of interest you would pay would be 5% of $100: $100(0.05) = $5.

The fee for borrowing money or other assets is known as interest. The borrowed sum is referred to as the principle.

Assuming no time constraint, let A= yearly amount invested at 3% and B= annual amount invested at 5%.

1800 is the total amount invested in both accounts.

66 is the total amount of interest earned in both accounts.

Marry wishes to divide the money into two halves.

A+B=1800

Interest earned in both accounts totals 0.03A+0.058=66.

We must now multiply both sides by 100 (3A+5B=6600).

Solving both equations yields A=1200 B=600.

Marry put $1200 into a 3%-interest-paying account.

And she put 600 dollars in a 5% interest account.

\( = \frac{4}{3} \times 3.14 \times {8.2}^{3} \)

The money loaned at 9% annual interest was 1500 and the money loaned at 11% annual interest was 19000.

Let the amount of money loaned at 9% be x

the amount of money loaned at 11% be y

According to the question,

Total money loaned = 20,500

Thus the equation formed is,

x + y = 20,500 ------ (i)

Simple interest is calculated by

I = P * r * t

where I is the simple interest

r is the rate of interest

t is the time

Thus, the interest on x = 0.09x

the interest on y = 0.11y

Total interest gained = 2,225

Thus the equation formed is,

0.09x + 0.11y = 2225 -------(ii)

Multiply (i) by 0.09

0.09x + 0.09y = 1845

Subtract the above from (ii)

0.02y = 380

y = 19000

Answer:

The solution is \(y(t) = \frac{4}{3} - \frac{1}{3} e^{_{-3} t}\\\)

Step-by-step explanation:

The question is:

Solve the initial value problem

y′′+3y'=0

y(0)=1

y′(0)=1

Step-by-step explanation:

First, we will write the characteristic equation, which is

\(x^{2} + 3x = 0\)

Then, we will solve for \(x\)

\(x^{2} + 3x = 0\) becomes

\(x(x+3) = 0\\\)

∴ \(x = 0\) or \(x +3 = 0\)

\(x = 0\) or \(x = -3\)

Hence, \(x_{1} = 0, x_{2} = -3\)

Since the two roots are distinct, that is, \(x_{1} \neq x_{2}\)

The general solution is

\(y(t) = C_{1}e^{x_{1} t} + C_{2}e^{x_{2} t}\\\)

Then,

\(y(t) = C_{1}e^{0 t} + C_{2}e^{-3 t}\)

\(y(t) = C_{1} + C_{2}e^{-3 t}\\\)

Then, for \(y'(t)\)

\(y'(t) = -3C_{2}e^{-3 t}\\\)

Now, from the question

y(0)=1

y′(0)=1

Then,

\(1 = y(0) = C_{1} + C_{2}e^{-3 (0)}\\\)

Then,

\(1 = C_{1} + C_{2}\) ........ (1)

Also,

\(1 = y'(0) = -3C_{2}e^{-3 (0)}\\\)

Then,

\(1 = -3C_{2}e^{-3 (0)}\\\)

\(1 = -3C_{2}\\\) ....... (2)

∴ \(C_{2} = - \frac{1}{3}\)

From equation (1)

\(1 = C_{1} + C_{2}\)

Then,

\(C_{1} = 1 - C_{2}\)

\(C_{1} = 1 - -\frac{1}{3} \\C_{1} = 1 +\frac{1}{3} \\C_{1} = \frac{4}{3}\)

Hence, \(C_{1} = \frac{4}{3}\) and \(C_{2} = - \frac{1}{3}\)

Then, the solution becomes

\(y(t) = \frac{4}{3} - \frac{1}{3} e^{_{-3} t}\\\)
