Paul is going to purchase orange juice and soda water for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of soda water as orange juice. If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle?

Answers

Answer:

10.5 bottles of orange juice

Step-by-step explanation:

Paul is going to purchase orange juice and soda water for a new fruit punch recipe. The recipe calls for 3.5 times as many bottles of soda water as orange juice. If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle?

Number of bottles of orange juice = x

Number of bottles of soda water = y

The recipe calls for 3.5 times as many bottles of soda water as orange juice.

Hence,

x = 3.5y

If he has $20.55, what is the most bottles of orange juice he can buy if orange juice costs $3.70 per bottle and soda water costs $0.90 per bottle

We have:

3.70y + 0.90× 3.5= 20.55

3.70y + 3.15y = 20.55

6.85 = 20.55

y = 20.55/6.85

y = 3 bottles

Since, Number of bottles of soda water = y, Number of bottles of soda water = 3

Note that: x = 3.5y

x = 3.5 × 3

x = 10.5 bottles

Number of bottles of orange juice = x, Hence, number of bottles of orange juice = 10.5 bottles

What is m Enter your answer in the box
m

Answers

Answer:

x = 30

Step-by-step explanation:

x + 2x + 3x = 180 (Add like terms)

6x = 180 (Divide both sides by 6)

x = 30

Therefore;

x = 30

2x = 60

3x = 90

X=30
3x=90
2x=60

If you are referring m as x then first we need to understand and realize how a triangle will ALWAYS equate to 180°.

With that being said a triangle will always have 3 angles, along with them all being able to be added up at equating 180. In this case all of our angles are related to x. We want to first add up all of our angles to equal 180 (x+2x+3x=180 OR 6x+180.) now that we have our equation, we want to solve for x so we need to isolate x first, in order to get 6 out of 6x we must divide by 6 on both sides of the equation which will then give us 180/6=30.

With x equating to 30 then we simply plug in our values for the angle. 3(30)= 90, 2(30)= 60 and x=30

If you divide 78 by 34, will the quotient be greater than or less than 34? (Please help I'm desperate)

Answers

Answer:

The quotient will be less than 34

Step-by-step explanation:

When we talk of quotient, we are simply referring to the result of division.

Now, let’s divide 78 by 34, our answer is 2 10/34. The answer is slightly above two which in all terms is really less than 34.

So the correct answer to our question is that the quotient will be less than 34

Line WV is perpendicular to both line RS and line TU.

On a coordinate plane, 3 lines are shown. Line V W goes through (negative 1, 5) and (1, 5). Line R S goes through (negative 5, 3) and (5, 1). Line T U goes through (negative 1, negative 2) and (4, negative 3).

Which statement must be true about line TU?

Line TU is parallel to line RS.
Line TU is perpendicular to line RS.
Line TU has no slope.
Line TU has a slope of –5

Answers

Answer:

Line TU is parallel to line RS

Step-by-step explanation:

I just got a 100 on the test

Line TU is parallel to line RS and has a slope of -1/5

What is a linear equation?

A linear equation is in the form:

y = mx + b

Where m is the slope and b is the y intercept.

Line V W goes through (-1, 5) and (1, 5). Line R S goes through (-5, 3) and (5, 1). Line T U goes through (-1,-2) and (4, -3).

Slope of VW = (5 - 5)/(1- (-1)) = 0

Slope of RS = (1 - 3) / (5 -(-5)) = -1/5

Slope of TU = (-3 - (-2))/(4 - (-1)) = -1/5

Line TU is parallel to line RS and has a slope of -1/5

When lava is expelled from a volcano, it temperature may vary from 700 degrees Celsius to 1200 degrees Celsius. Write an absolute value equation that represents the minimum and maximum temperatures of lava. Use x to represent the temperature.

Equation:__

Answers

Answer:

Ix - 950°C I ≤ 250°C

Step-by-step explanation:

We are told that the temperature may vary from 700 degrees Celsius to 1200 degrees Celsius.

And that this temperature is x.

This means that the minimum value of x is 700°C while maximum of x is 1200 °C

Let's find the average of the two temperature limits given:

x_avg = (700 + 1200)/2 =

x_avg = 1900/2

x_avg = 950 °C

Now let's find the distance between the average and either maximum or minimum.

d_avg = (1200 - 700)/2

d_avg = 500/2

d_avg = 250°C.

Now absolute value equation will be in the form of;

Ix - x_avgI ≤ d_avg

Thus;

Ix - 950°C I ≤ 250°C

Answers

Answer:

$12.50

Step-by-step explanation:

18 - 12 = 6

Brandon bought 6 less than Lance and payed $75 dollars shoes.

That means that 6 shirts cost $75.

We need to divide 6 from 75

75/6 = 12.5

So each shirt costs $12.50.

Sheryl got the following scores on her spelling tests.

Mean = sum of all observations/ Number of observations

Sum of all observations [tex]=95+89+99+85+82=450[/tex]

Number of observations = 5

So,

Mean [tex]=\frac{450}{5}=90[/tex]

Let M denotes the mean

Mean absolute deviation [tex]=\frac{\sum_{i=1}^{n}\left | x_i-M \right |}{n}[/tex]

Put [tex]n=5[/tex]

So,

Mean absolute deviation [tex]=\frac{\sum_{i=1}^{5}\left | x_i-M \right |}{5}=\frac{|95-90|+|89-90|+|99-90|+|85-90|+|82-90|}{5}=\frac{5+1+9+5+8}{5} =\frac{28}{5}=5.6[/tex]

Alex bar and Carl are brothers Alex is the oldest and Carl is the youngest the some of the ages of the three brothers is 42 Alex his age is three more than twice Carl's age the difference between Barts in Carl's ages is seven years how old is each brother

Answers

Answer:

Alex = 19 years

Bart's = 15 years

Carl = 8 years

Step-by-step explanation:

Let us represent their ages as

Alex = x

Bart's = y

Carl = z

the sum of the ages of the three brothers is 42

x + y + z = 42

Alex his age is three more than twice Carl's age

x = 2z + 3

The difference between Barts in Carl's ages is seven years

y - z = 7

y = 7 + z

Hence: we Substitute

x + y + z = 42

2z + 3 + 7 + z + z = 42

Collect like terms

2z + z + z + 10 = 42

4z = 42 - 10

4z = 32

z = 32/4

z = 8 years

Hence, Carl = 8 years old

a) y = 7 + z

y = 7 + 8

y = 15 years.

Hence, Bart's is 15 years old

b)x = 2z + 3

x = 2(8) + 3

= 16 + 3

= 19 years

Therefore, Alex is 19 years old.
