So you know that 11 U.S. Dollars can be exchanged for 10 Euros which is 10/11. To figure out how many Euros you will receive for 1 Dollor you have to find the unit rate. To do this divide 10 by 11. The answer is 0.90

Answer:

0.91 Euros

Step-by-step explanation:

We know that 11 U.S. Dollars can be exchanged for 10 Euros. We know that exists a linear relationship between the amount of U.S Dollars and the amount of Euros. This linear relationship can be written as :

$\frac{11(U.S.Dollars)}{10(Euros)}=\frac{1(U.S.Dollars)}{x}$

If we solve the equation for x :

$x=\frac{1(U.S.Dollars).10(Euros)}{11(U.S.Dollars)}=\frac{10}{11}(Euros)$

$x=0.9090(Euros)$ ≅ 0.91 Euros

We find that for 1 U.S.Dollar I will receive 0.91 Euros.

Bakery has bought 250 pounds of muffin dough. They want to make waffles or muffins in half-dozen packs out of it. Half a dozen o

Answer:

250 batches of muffins and 0 waffles.

Step-by-step explanation:

-1

If we denote the number of batches of muffins as "a" and the number of batches of waffles as "b," we are then supposed to maximize the profit function

P = 2a + 1.5b

subject to the following constraints: a>=0, b>=0, a + (3/4)b <= 250, and 3a + 6b <= 1200. The third constraint can be rewritten as 4a + 3b <= 1000.

Use the simplex method on these coefficients, and you should find the maximum profit to be $500 when a = 250 and b = 0. So, make 250 batches of muffins, no waffles.

You use up all the dough, have 450 minutes left, and have $500 profit, the maximum amount.

Answer:

2 $\sqrt{5}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{125}$ = $\sqrt{25(5)}$ = $\sqrt{25}$ × $\sqrt{5}$ = 5 $\sqrt{5}$

$\sqrt{180}$ = $\sqrt{36(5)}$ = $\sqrt{36}$ × $\sqrt{5}$ = 6 $\sqrt{5}$

$\sqrt{45}$ = $\sqrt{9(5)}$ = $\sqrt{9}$ × $\sqrt{5}$ = 3 $\sqrt{5}$

Thus

$\sqrt{125}$ - $\sqrt{180}$ + $\sqrt{45}$

= 5 $\sqrt{5}$ - 6 $\sqrt{5}$ + 3 $\sqrt{5}$

= 2 $\sqrt{5}$

Jack rolls a number cube twice. What is the probability that the sum of the 2 rolls is less than 8 given that the first roll is

disa [49]

If the first roll is a 4, the possibilities to add less than 8 are that the second cube roll is 1, 2 or 3.

These are 3 different events out of 6 possilbe ones, which is 3 / 6 = 1 / 2; i.e. half of times.

Then the answer is the first option: 1 / 2
