610 divided by 4 because when you divide that you will get 152

Answer:

610\div 4

Step-by-step explanation:

In a division problem,

Dividend ÷ Divisor

We check the answer by the formula,

Dividend = quotient × divisor + remainder,

Here, the verification equation,

610 = 152 × 4 + 2,

By comparing,

We get, dividend = 610, divisor = 4,

The required problem would be,

610\div 4

The length of a rectangle is increasing at a rate of 4 meters per day and the width is increasing at a rate of 1 meter per day.

Answer:

\displaystyle \frac{dA}{dt} = 102 \ m^2/day

  • w is width

Implicit Differentiation

Differentiation with respect to time

Derivative Rule [Product Rule]:                                                                              \displaystyle \frac{d}{dx} [f(x)g(x)]=f'(x)g(x) + g'(x)f(x)

Step-by-step explanation:

<u>Step 1: Define</u>

<u />\displaystyle l = 10 \ meters<u />

<u />\displaystyle \frac{dl}{dt} = 4 \ m/day<u />

<u />\displaystyle w = 23 \ meters<u />

<u />\displaystyle \frac{dw}{dt} = 1 \ m/day<u />

<u />

<u>Step 2: Differentiate</u>

  1. [Area of Rectangle] Product Rule:                                                                 \displaystyle \frac{dA}{dt} = l\frac{dw}{dt} + w\frac{dl}{dt}

<u>Step 3: Solve</u>

  1. [Rate] Substitute in variables [Derivative]:                                                    \displaystyle \frac{dA}{dt} = (10 \ m)(1 \ m/day) + (23 \ m)(4 \ m/day)
  2. [Rate] Multiply:                                                                                                \displaystyle \frac{dA}{dt} = 10 \ m^2/day + 92 \ m^2/day
  3. [Rate] Add:                                                                                                      \displaystyle \frac{dA}{dt} = 102 \ m^2/day

a store selling a couch for $623 on a 24 month payment plan if your down payment of 152 is given and no interest is charged how
sveticcg [70]
First start with $623 and subtract the $152 deposit. Then divide that answer by 24, which equals 19.625. The monthly payment would be 19.63 monthly for 24 months.

Mina tosses two number cubes labeled 1 to 6. What is the probability that the sum is equal to five?
coldgirl [10]

(1,4)

(4,1)

(2,3)

(3,2)

so there are 4 different combinations that equal 5

 6 x 6 = 36 total possible outcomes of the dice

so they have a 4/36 reduces to 1/9 probability of equaling 5
