Elenna [48]

1(Identifying):

Tomatoes-x--$3 per lb

Mushrooms- 1/3 x-- $10 per lb

Peaches- x+1-- $6 per lb

2(Equation):

3x+6(x+1)+1/3x*10=80

3x+6x+6+10/3 x=80

12 1/3 x= 74

x=74÷(12+1/3)

Step 3(Final Equations):

74*3/37=6=tomatoes

Meaning...

6+1=7=Peaches

6/3=2= mushrooms

Answer:

How many three letter permutations can be formed from the first five letters of the alphabet?

Vsevolod [243]

Answer:

There are 60 permutations that can be formed from the first five letters of the alphabet.

Step-by-step explanation:

The number of three letter permutations that can be formed from the first five letters of the alphabet is $5P_{3}$ .

$5P_{3} =\frac{5!}{(5-3)!}$

$=\frac{5!}{2!}$

= 60

Hence, there are 60 permutations that can be formed from the first five letters of the alphabet.

Someone please help with trig question ASAP!!!! You dont need to do both! Will mark brainliest if right

Zanzabum

Answer:

8 x = 60.10251159

9 x = 3.66062978

Step-by-step explanation:

Hey There!

So to answer these questions we need to use the Law of sines

Consider the following image

So to find x in number 8 we setup an equation

$\frac{x}{sin90} =\frac{48}{sin53}$

now we solve for x

step 1 multiply each side by sin 90

now we have

$x = \frac{48sin90}{sin53}$

if you plug the equation in a calculator you get that

x=60.10251159

<u>( make sure if it says to round to the nearest.... that you round before entering your answer)</u>

For number 9 the equation would be

$\frac{9}{sin90} =\frac{x}{sin24}$

now we solve for x

step 1 multiply each side by sin 24

now we have

$x=\frac{9sin24}{sin90}$

if you plug this into a calculator you get that

x = 3.66062978

<u>(once again if it says to round to the nearest... make sure you round before you put in your answer.)</u>
