Eight cookies and 3 muffins cost $13Four cookies and six muffins cost $11.How much does a cookie cost? How much does a muffin co

NeTakaya

Answer:

the cost of each cookie is $\$1.25$

the cost of each muffin is $\$1.00$

Step-by-step explanation:

Let

x-----> the cost of each cookie

y----> the cost of each muffin

we know that

$8x+3y=13$ -----> equation A

$4x+6y=11$ -----> equation B

Using a graphing tool

The solution of the system of equations is the intersection point both graphs

The intersection point is $(1.25,1)$

see the attached figure

therefore

the cost of each cookie is $\$1.25$

the cost of each muffin is $\$1.00$

A welder's electrical arc has a temperature ranging from 500°C to 20 000°C. What is this in degrees Fahrenheit?

DochEvi [55]

<h3>Answer:</h3>

932°F to 36032°F

<h3>Step-by-step explanation:</h3>

Celsius and Fahrenheit are both measures of temperature. However, Celsius is a metric measurement, and Fahrenheit is used in the USA primarily.

Conversion Formula

To convert the Celsius measurements to Fahrenheit we can use the formula:

(°C × 9/5) + 32 = °F

So, in this formula, you can plug in whatever Celsius value you have in and solve for Fahrenheit. To convert from F to C you can use the second formula:

(°F − 32) × 5/9 = °C

Solving for Fahrenheit

Now that we have the formula, we can plug in the 2 Celsius values to find the new range.

First, plug 500°C in

(500°C × 9/5) +32 = °F

Next, multiply the terms within the parentheses

(900) + 32 = °F

Finally, add the last terms

932 = °F

Then, plug in 20000°C

(20000°C × 9/5) + 32 = °F

Next, multiply the terms within the parentheses

(36000) + 32 = °F

Lastly, add the terms together

36032 = °F

This means that, in Fahrenheit, the temperature range of the welder's electrical arc is 932°F to 36032°F. This is a total range of 35100°F.
