On a trip, you had to change your money from dollars to euros. You got 450 euros for 600 dollars. Which is a unit rate that desc

chubhunter [2.5K]

The number of Euros received against 600 dollars = 450
Then
For 1 dollar, the number of euros = (450/600) euros
   = (45/60) euros
   = ( 3/4) euros
   = 0.75 euros
So the unit rate that describes the exchange rate is 0.75 euros per dollar. So the correct option among all the options given in the question is option "A". I hope the procedure for getting to the correct result is clear enough for you to understand. In future you can use this procedure for solving similar problems.

It takes Evan 6 3/4 hours to mow 3 lawns. it takes him 2 1/3 hours to mow Mr. Smiths yard and 1 3/4 hours to mow Ms. Lee's yard.

Ratling [72]

Answer: $2\frac{2}{3}\ hours$

Step-by-step explanation:

Given: The total time taken by Evan to mow the 3 lawns = $6\frac{3}{4}=\frac{27}{4}\ \text{hours}$

Time taken by Evan to mow the first lawn = $2\frac{1}{3}=\frac{7}{3}\ \text{hours}$

Time taken by Evan to mow the second lawn = $1\frac{3}{4}=\frac{7}{4}\ \text{hours}$

Now,Time taken by Evan to mow the third lawn = $\frac{27}{4}-\frac{7}{3}-\frac{7}{4}$

⇒Time taken by Evan to mow the third lawn = $\frac{81-28-21}{12}$

⇒Time taken by Evan to mow the third lawn = $\frac{32}{12}=\frac{8}{3}=2\frac{2}{3}\ hours$

Hence, the time taken by Evan to mow the third lawn = $2\frac{2}{3}\ hours$

The lengths of a triangle are 12 and 23 meters find the range of possible lengths for the third side

sergij07 [2.7K]

Answer: 11 < x < 35

suppose: the length of the third side is x

because x is the third side of a triangle

=> 23 - 12 < x < 23 + 12

⇔ 11 < x < 35

Bogdan [553]

<span>The answer is 167 milliliters of 7% solution and 333 milliliters of 4% solution x + y = 500 x = 500 - y 0.07x + 0.04y = 25 (substitute 500 - y for x) 0.07(500 - y) + 0.04y = 25 35 - 0.07y + 0.04y = 25 -0.03y + 35 = 25 -0.03y = -10 y = 333.333... y [ = about 333 x = 500 - y = 500 - 333 = 167 hope it helps </span>
