Well we know that every 2 eggs requir 1 and 3/4 of flour so the easiest thing to do here (for me at least) is to round the fraction to the nearest whole number which in this case will be 1. Now that that's done we can say every 2 eggs calls for 2 cups of flour. Now all you need to do is multiply 2 by 9 to get 18 then put that in fraction form it'll be 17 and 3/4 cups of flour. I hope this helps!

Un círculo tiene un radio de 5 cm. ¿Cuántos centímetros mide su circunferencia?

denpristay [2]

Answer:

10\pi[/tex]

Step-by-step explanation:

Circunferencia de un círculo = Pi veces diámetro

como el diámetro es igual a la mitad del radio, sabemos que si multiplicamos el radio por dos obtendremos el diámetro del círculo. Por lo tanto, 5 veces 2 = 10. Ahora hacemos 10 veces pi. El cual es 10 pi o 31.4159

Circumference of a circle = Pi times diameter

since the diameter is equal to half the radius, we know that if we multiply the radius by two we will obtain the diameter of the circle. Therefore, 5 times 2 = 10. Now we do 10 times pi. Which is 10 pi or 31.4159

You are running a fuel economy study. One of the cars you find is blue. It can travel 44 and one half miles on 1 and one fourth

Radda [10]

Unit rate of blue car is 35.6 miles/gallon and unit rate of red car is 36 miles/gallon. The red car could travel the greater distance on 1 gallon of gasoline.

Explanation

Unit rate for each car can be calculated using the below formula...

Unit rate = (Distance traveled) / (Amount of gasoline)

For Blue car, distance traveled $=44\frac{1}{2} = \frac{89}{2} miles$ and amount of gasoline $=1 \frac{1}{4}= \frac{5}{4} gallons$

So, the unit rate for blue car = $\frac{89}{2}$ ÷ $\frac{5}{4}$ = $\frac{89}{2}$ × $\frac{4}{5}$ = $\frac{356}{10} = 35.6$ miles/gallon

Now for Red car, distance traveled $= 28\frac{4}{5} = \frac{144}{5} miles$ and amount of gasoline $= \frac{4}{5} gallons$

So, the unit rate for red car = $\frac{144}{5}$ ÷ $\frac{4}{5}$ = $\frac{144}{5}$ × $\frac{5}{4}$ = $\frac{144}{4} = 36$ miles/gallon

As the unit rate for red car is greater than the blue car, that means the Red car could travel the greater distance on 1 gallon of gasoline.
