A recipe that yields 12 of soup calls for 28 ounces of beef broth. How many ounces of beef broth do you need to make 18 cups of

Luba_88 [7]

Answer:

we know that

A recipe that yields 12 cups of soup calls for 28 ounces of beef broth

by proportion

Find the ounces of beef broth needed to make 18 cups of soup

\frac{28}{12} \frac{ounces}{cups} =\frac{x}{18} \frac{ounces}{cups} \\ \\12*x=18*28\\ \\x=18*28/12\\ \\x=42\ ounces

therefore

the answer is

42\ ounces

If $x$, $y$, and $z$ are positive integers such that $6xyz+30xy+21xz+2yz+105x+10y+7z=812$, find $x+y+z$.

harina [27]

Answer:

Step-by-step explanation:

When we simplify we get $z(6xy+21x+2y+7)+30xy+105x+10y=812.$

Then we continue to factor to get: $(z+5)(6xy+21x+2y+7)&=847.$

We then see that we can factor $(6xy+21x+2y+7)$ into $(z+5)(3x+1)(2y+7)&=847.$

we then do the prime factorization of 847, which i think is, $7*11*11$ . we have to find the numbers that multiply to 847 and then plug them into z+5, 3x=1,2y+7.

It has to be a positive, non-negative integer, right?

We also see that 3x+1=11 so we see that x=10/3 (which wont work).

So 3x+1=7, so x=2.

So 11 has to be in another term. It has to be in 2y+7=11 so y=2

for the last term we get z+5=11 so z=6

2+2+6=10

Hope this helps and if you want please consider giving me brainliest. :)

4px = 20 <br> (find p) <br> -4px = 20<br> (find x)

Kazeer [188]

Answer:

4px=20

x=(20/4p)-----(1)

-4px=20--------(2)

putting value of x in epn 2

-4p*20=20*4p

-80p=+80p

Both cut these value are rejected

Checkout the question again bro it might be wrong

Please for my hard work make me brainliest answer

Which table correctly shows all the sample spaces for tossing a coin to get heads and rolling a number on a six-sided number cub

Lelechka [254]

Using it's concept, the sample space for the experiment is given as follows:

{(H,1), (H,2), (H,3), (H,4), (H,5), (H,6), (T,1), (T,2), (T,3), (T,4), (T,5), (T,6)}

<h3>What is the sample space of an experiment?</h3>

The sample space is the set that contains all possible outcomes for an experiment.

In this problem:

For the coin, there are 2 outcomes, H for heads and T for tails.

For the number, there are 6 outcomes, which are the 6 numbers.

Hence the sample space is given as follows:
{(H,1), (H,2), (H,3), (H,4), (H,5), (H,6), (T,1), (T,2), (T,3), (T,4), (T,5), (T,6)}
