The puppy shelter where Isaac works is moving to a new building. The rooms in the new building are built to hold 6 puppies each. Isaac needs to figure out how many rooms he'll need to house a total of 78 puppies.
Use an equation to find the number of rooms Isaac needs.

Answer:

There are 22 $10 coins and 21 $20 coins.

Step-by-step explanation:

Let x = the number of $10 coins

Let y = the number of $20 coins

You have two unknows so you need two equations.

x + y = 43

10x + 20y = 640.

Rewrite the first equation solving for x

x + y = 43

x = 43 - y  Substitute 43 - y in for x in the second equation.

10x + 20 y = 640

10(43 - y) + 20y = 640

430 - 10y + 20y = 640  Subtract 430 from both sides of the equation

-10y + 20y = 210  Combine the y's

10y = 210  Divide both sides by 10

y = 21  This is the number of $20 coins.

Substitute 21 in for y in either of the original equations to solve for x

x + 21 = 43  Subtract 21 from both sides

x = 22  This is the number of $10 coin.

Check:

Substitute in 21 for y and 22  for x

x + y = 43

21 + 22 = 43

43 = 43  checks

10x + 20y = 640

10(22) + 20(21) = 640

220 + 420 = 640

640 = 640 Checks

Step-by-step explanation:

The solution for the unknown variable in I = PRT where I = 2160, P =24000 and R = 0.03 is 3

The given parameters are

I = PRT

Where

I = 2160, P =24000 and R = 0.03

Substitute I = 2160, P =24000 and R = 0.03 in the above equation I = PRT

2160 = 24000 * 0.03 * T

Evaluate the product

So, we have

2160 = 720 * T

Divide both sides by 720

T = 3

Hence, the solution for the unknown variable in I = PRT where I = 2160, P =24000 and R = 0.03 is 3

The formula that correctly solves for C is D. C = 5/9 (F - 32)

In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .

The given formula is,

F = 9/5C + 32

where Celsius is C, and degrees Fahrenheit is F

To solve for C let us isolate C to the one side and other terms to the other,

9/5 C = F - 32

Multiplying both side by 5/9 we get,

9/5 C *5/9 = 5/9* (F - 32)

or, C = 5/9 (F - 32)

which is the formula for C.

Thus, the formula that correctly solves for C is D. C = 5/9 (F - 32)

D is a rigt answer.

Step-by-step explanation:

D is a right answer

The interest earned on even a $30,000 deposit compounded monthly at 1% is $15150.75.

Compound interest is applied when the principal amount changes after the specified time period.

For example, if you give someone $500 at a 10% yearly interest rate, $500 is your principal amount. After one year, the interest will be $50, and the principle amount will indeed be $550; therefore, the interest for the following year will be $550, not $500.

P = P₀e^rt where r represents the annual interest rate as well as t represents the time period in years.

So,

P₀ = 30000

r = 1% = 0.01

t = 6 months = 0.5 year

So,

P = 30000e^0.01(0.5)

P = 30000 × 1.5050250835

P = $45150.752505

So, interest

I =45150.752505- 30000 = $15150.75

The interest earned on even a $30,000 deposit over six months at 1% compounded daily is $15150.75

The researchers came up with this number by making a model with specific coins to determine the difficulty, in terms of the probability of getting this coin.

The researchers Shiyoung Lu and Steven Skiena wanted to know how probable it was to collect a complete set of pennies since 1959 until 1997. By the end of this study, they decided at least 684 coins must be collected to complete this mission.

Firstly, they analyze the probability for getting one coin. From this, it was concluded the probabillity was lower for old coins. After this, they used the data collected from all the coins and created an equation. This equation or model led them to conclude the answer was 684 coins.

In linear equation ,The truck's relative position with respect to the car is 100 feet

What is linear equation ?

If the truck is moving at a seed "V" then its position after 8 seconds is going to be:

XT = V* t = V * 8 = 8 V

The car, which is initially 60 feet ahead of the truck and starts moving at 5 m/s faster than the truck, would have a speed given by: V + 5

And its position (relative to the truck's) would be:

XC = 60 + (V + 5) * t = 60 + (V + 5) * 8 = 60 + 40 + 8 V = 100ft + 8 V

then the position of the truck relative to that of the car would be given by the difference:

XT - XC = 8 V - (100 +8 V) = 8 V - 8 V - 100ft = -100 feet

According to the statement, water percentage is equal to the ratio of water mass divided by the total mass of water and dust and multiplied by 100. Then, the initial and final percentages are defined below:

Initial percentage

y / 5 = 0.12                              (1)

Final percentage

(y + x) / (5 + x) = 0.28             (2)

Then, we need to resolve the resulting system of linear equations:

y = 0.6                  (1)

y + x = 1.4 + 0.28 · x

0.72 · x = 1.4 - y

x = 1.944 - 1.389 · y

x = 1.111

We need to add 1.111 kilograms of water. If the density of a kilogram per liter, the volume required in liters is:
