Find the difference. 256,805 - 136,667 *

The required system of the equation that represents the number of quarters, q, and the number of dimes, d, in the jar is 0.10d + 0.25q = 8 and d + q = 50.

Given that,
Ronny is taking a jar with 50 dimes and quarters to Coin Master to redeem for dollar bills. The total value of his jar is $8.

Simultaneous linear equations are two- or three-variable linear equations that can be solved together to arrive at a common solution.

Here,
Let the number of the dimes be d and the number of the quarters be q,
According to the question,
The total of the coins is 50,
d + q = 50,
And this coins values is $8,
0.10d + 0.25q = 50   [sinnce value of one dime = 0.10 and value of one quarter is 0.25]

Thus, the required system of the equation that represents the number of quarters, q, and the number of dimes, d, in the jar is 0.10d + 0.25q = 8 and d + q = 50.

if m what? I'm confused

Answer:

292.50 dollars

Step-by-step explanation:

P = 650 is the the principal.

r = 0.09 is the interest rate in decimal form.

t = 5 is the number of years.

i = 650*0.09*5

i = 292.50 is the simple interest.

Answer:

No, The 8 in the ones place of the decimal and the 8 in the thousands. Decimals go by variables of 10 if that makes sense

so hopping from the 8 in the ones place it would go 10, 100,1000.

Therefore the statement is false because the value between the eitghts is not 100 its 1000

Answer:

The value is  [tex]E(X) = 4 \ days[/tex]

Step-by-step explanation:

From the question we are told that

   The mean is  [tex]\mu = 36^oC[/tex]

    The standard deviation [tex]\sigma = 3^oC[/tex]

Generally the probability that in June , the midday  temperature is between  

39°C and 42°C is mathematically represented as

      [tex]P(39 < X < 42) = P(\frac{39 - 36}{3} < \frac{X - \mu }{\sigma} < (\frac{42 - 36}{3} )[/tex]

[tex]\frac{X -\mu}{\sigma }  =  Z (The  \ standardized \  value\  of  \ X )[/tex]

      [tex]P(39 < X < 42) = P(1 < Z <2 )[/tex]

=>   [tex]P(39 < X < 42) = P(Z < 2) - P( Z <1 )[/tex]

From the z table  the area under the normal curve to the left corresponding to  1 and  2  is

     P(Z   < 2)  = 0.97725

and

    P(Z   < 1)  = 0.84134

    [tex]P(39 < X < 42) = 0.97725 - 0.84134[/tex]

=>  [tex]P(39 < X < 42) = 0.13591[/tex]

Generally number of days in June would you expect the midday temperature to be between 39°C and 42°C

      [tex]E(X) = n * P(39 < X 42 )[/tex]

Here n is the number of days in June which is  n = 30

       [tex]E(X) = 30 * 0.13591[/tex]

=>    [tex]E(X) = 4 \ days[/tex]

Slope-Intercept Form: y = mx + b

Step-by-step explanation:

Step 1: Define

Slope m = 1

y-intercept b = -2

Step 2: Write linear function

y = x - 2

Answer: B, y=x-2

Step-by-step explanation:

The slope-intercept form is y=mx+b where m=slope and b=y intercept

therfore, subtituting 1 for m and -2 for b

y=x-2

Answer:

x=  25 /2  and/or 12.5

Step-by-step explanation:

Let's solve your equation step-by-step.

300x+6250=10000

Step 1: Subtract 6250 from both sides.

300x+6250−6250=10000−6250

300x=3750

Step 2: Divide both sides by 300.

300x /300 = 3750 /300

x= 25 /2

Answer: X is 3450
