11. The sales tax rate is 6.9%

Norma-Jean [14]3 years ago

Answer:

40.1%

Step-by-step explanation:

I am assuming that 192 is in 100%.

100% = 192

I then represent the value that we are looking for with x.

x% = 77

By dividing both equations (100% = 192 and x% = 77) and remembering that both left hand sides of BOTH equations have the percentage unit (%).

\frac{100}{x} = \frac{77}{192}

Now, of course, we take the reciprocal, or inverse, of both sides:

\frac{x}{100} = \frac{7}{192}

x = 40.1%

Thus making the answer: 40.1% of 192 is 77.

Every time Martina orders Chinese food, she gets egg drop soup. So, she decides to learn how to make it herself. Her recipe call
MrRa [10]

Answer:

2 cartons

Step-by-step explanation:

Hey! To start, we need to determine what we already know, Martine needs 8 cups worth of broth, but can only find 32-fluid ounce cartons.

Next, we need to find what we need to know, how many fluid ounces are in a cup? <em>There are 8 fluid ounces in 1 cup!</em>

Now, all we need to do is convert our cups to be able to find out how many cartons we need! So, to do this, we are going to multiply our number of cups by the number of fluid ounces in just 1 cup (so 8!).

<em>8 cups x 8 fluid ounces (per 1 cup) = 64 fluid ounces</em>

So! Martina needs 64 fluid ounces of broth to be able to create her recipe!

<em>But, we aren't finished just yet, as we need to find how many cartons Martina needs! Like we did before, we know that there a 32 fluid ounces in 1 carton so if we have 64 fluid ounces in the recipe, all we need to do is divide 64 by 32 to find out how many cartons we need!</em>

<em>64 fluid ounces (8 cups worth) ÷ 32 fluid ounces (per carton) = 2 cartons</em>

Melina needs to buy 2 cartons of broth to be able to complete her recipe.

Hope this Helps! :)

Hello,

Let's assume f the age of the father,
s the age of the son.

<span>The age of a father is 2 less than 7 times the age of his son ==> f=7s-2 (1)

</span>
<span>In 3 years, the sum of their ages will be 52 ==>(f+3)+(s+3)=52 (2)

(2)==>f+s+6=52
==>f+s=46 (3)
(3) and (1) ==>7s-2+s=46
==>8s=48
==>s=6
f=46-6=40
