Answer:

Step-by-step explanation:

step one:

given data

pecans sell for $1.60 per pound

walnuts sell for $2.20 per pound

mixture sells for $2 per pound  

Required: the amount in pounds of walnuts

Step two:

let he amount in pounds for the walnuts be x pounds

the amount in pounds of the mixture is

(5+x ) pounds

The cost of the mixture is

5*1.6 +x*2.2 = 2(5+x)

solve for x

8+2.2x=10+2x

collect like terms

8-10=2x-2.2x

-2=-0.2x

rearrange

0.2x=2

divide through by 0.2

x=2/0.2

x=10 pounds of walnuts

Answer:

5/3

Step-by-step explanation:

30/t = 18/r

Multiplying by r both sides,

30*r /t = 18

Dividing by 30 both sides,

r/t = 18/30 = 3/5

So, t/r = 5/3

9514 1404 393

Answer:

  t/r = 5/3

Step-by-step explanation:

Every proportion can be written 4 ways. I like to think of them as "upside down and sideways." They are ...

  [tex]\dfrac{30}{t}=\dfrac{18}{r}\qquad\dfrac{t}{30}=\dfrac{r}{18}\\\\\dfrac{30}{18}=\dfrac{t}{r}\qquad\dfrac{18}{30}=\dfrac{r}{t}[/tex]

__

Knowing this, you can simply rewrite your proportion as ...

  t/r = 30/18

  t/r = 5/3

_____

More formally, you could multiply both sides by t/18:

  (30/t)(t/18) = (18/r)(t/18)

  30/18 = t/r . . . . as above

Reducing the fraction gives ...

  t/r = 5/3

__

Additional comments

The usually-recommended procedure for solving something like this is to "cross-multiply" as a first step. That will give ...

  30r = 18t

Of course, that is equivalent to multiplying both sides by rt, the product of the denominators.

From here, to get t/r, you need to divide both sides by 18r.

  (30r)/(18r) = (18t)/(18r)

  30/18 = t/r

The combination of the two steps, multiply by rt, divide by 18r, is equivalent to multiplying by (rt)/(18r) = t/18, as we did above. That is, you can save some work by doing both steps at once--or by simply rewriting the proportion.

Given:

Temperature in the morning = -2 degrees.

Temperature is dropping at a constant rate.

Temperature after 4 hours = -22 degrees.

To find:

The rate of change of temperature.

Solution:

Let y be the temperature after x hours from the morning.

Temperature in the morning is -2 degrees. It means, the ordered pair is (0,-2).

4 hours later the temperature is now -22 degrees. It means, the ordered pair is (4,-22).

Now, formula for average rate of change or slope is

[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

[tex]m=\dfrac{-22-(-2)}{4-0}[/tex]

[tex]m=\dfrac{-22+2}{4}[/tex]

[tex]m=\dfrac{-20}{4}[/tex]

[tex]m=-5[/tex]

Therefore, the change in temperature is -5 per hour. It means the permutate is decreasing by 5 degrees per hour.

Step-by-step explanation: Each game is $25.50 which in math means it has an "x"

So if x=1 then 25.50x says that 1 video game is $25.50

Set up the equation:

200 = 25.50x (divide both sides by 25.50 to isolate the x)

200/25.50 = 7.84

x = 7.84

You can't have 0.84 of a video game, so Roberto can only buy 7 of them.   The answer is correct good job!

The number of games that Roberto can buy [tex]\boldsymbol{8}[/tex] video games.

"To understand the calculation, check below."

When two values are compared, an inequality shows whether one is less than, greater than, or simply not equal to the other.

It's a relation that compares two integers or other mathematical expressions in a non-equal way.

Total amount with Roberto [tex]=\$ 200[/tex]

Let [tex]x[/tex] denotes number of games that Roberto can buy.

Cost of each video game [tex]=\$25.50[/tex]

So,[tex]25.50x\leq 200\\x\leq 7.8[/tex]

Therefore, Roberto can buy [tex]\boldsymbol{8}[/tex] video games.

i think it is Move the decimal after the number 1.

Step-by-step explanation:

it the text it says

"To convert our example, 602,200,000,000,000,000,000,000, into a scientific notation, the first step is to place a decimal after the digit 6, and then drop all the zeros after the 2. This will leave us with a coefficient of 6.022. Next, to find the exponent, count the number of times you had to move the decimal point until it landed after the first digit of the coefficient. The answer is 23; therefore, the scientific notation is 6.022 x 1023. In cases where the numbers are multiples of 10, only the base number 10 and the exponent can be used. For instance, the number 1,000,000,000, can be written as 109. Now you try it. What is the scientific notation for a light year, which has been estimated at 9,500,000,000,000 km?

Given:

Wholesale price = $5

They sell them after a markup of 75%.

To find:

The amount of mark up and the retail price.

Solution:

We have,

Wholesale price = $5

Markup% = 75%

[tex]Markup=5\times \dfrac{75}{100}[/tex]

[tex]Markup=5\times 0.75[/tex]

[tex]Markup=3.75[/tex]

Now,

Retail price = Wholesale price + Markup

[tex]\text{Retail price}=5+3.75[/tex]

[tex]\text{Retail price}=8.75[/tex]

Therefore, the markup price is $3.75 and retail price is $8.75.

Answer:

Oil changes = 5

Vincent = 10 oil changes

Warren = 10 oil changes

Step-by-step explanation:

Vincent = 5 + h

Warren = 2h

Where,

h = number of oil changes

How long will that take?

Vincent = Warren

5 + h = 2h

5 = 2h - h

5 = h

h = 5

Number of oil changes = 5

How many oil changes will Vincent and Warren each have done?

Vincent = 5 + h

= 5 + 5

= 10 oil changes

Warren = 2h

= 2(5)

= 10 oil changes
