Consider the equation 22+3x/3x+7=2 How do you begin isolating the variable x to one side of the equation?

Answers

You have 22+3x/3x+7=2. That 3x/3x raises eyebrows; is this what you meant, with the result that 3x/3x = 1? or did you mean

3x

22 + ------------- + 7 = 2?

3x+7

If you meant the latter, then simplify the equation by subtracting 2 from both sides:

3x

27 + ---------- = 0

3x+7

Multiply all three terms by (3x+7), obtaining

27(3x+7) + 3x = 0

Then 21x + 3x + 189 = 0, so that 24x = -189, or x = -189/24 = -7 7/8

If a Rubik’s Cube has a volume of 384 cubic centimeters, how long is one side of the cube?

Answers

The answer is:  "7.268 cm" .
________________________
Explanation:
________________________
Since the formula for the volume, "V", of a cube, is:

V = s³ ;

in which:  "s" = side length of a cube;

Given:  "V = 384 cm³ " ;  Plug this value into the formula; to solve for "s" ;

V = s³ ;

↔  s³ = V ; 

     s³ = V ; 

     s³ = 384 cm³ ;

Take the "cubic root" of EACH SIDE of the equation; to isolate "s" on one side of the equation ; & to solve for "s" ; 
_________________________________________________
   ∛(s³) = ∛ (384 cm³) ;

     s =   7.2684823713285586  cm

Round to:  7.268 cm .

An architectural drawing lists the scale as 1/4" = 1'. If a bedroom measures 1.5" by 2.25" on the drawing, how large is the bedroom?

Answers

Final answer:

The scale of the architectural drawing is such that 1/4" represents 1'. This means, if the room measures 1.5" by 2.25" on the drawing, it measures 6 feet by 9 feet in real life.

Explanation:

In this scenario, the unit scale indicates that 1/4" on the drawing represents 1' in real life. So, to find the real-life dimensions of the room, you would need to convert the drawing dimensions to real-life dimensions.

For the length, 1.5" on the drawing would equate to 1.5 * 4 feet because every 1/4" equals 1 foot. Therefore, the length of the room is 6 feet.

The width of the room is similarly calculated. 2.25" on the drawing would equate to 2.25 * 4 feet which gives us a width of 9 feet.

So, the bedroom in real life is 6 feet by 9 feet.

#SPJ12

Final answer:

The bedroom is 6 feet by 9 feet in real life.

Explanation:

To determine the actual size of the bedroom, we can use the scale given in the architectural drawing. The scale 1/4" = 1' means that every 1/4 inch on the drawing represents 1 foot in real life. In this case, the bedroom measures 1.5 inches by 2.25 inches on the drawing. To find the actual size, we can multiply these dimensions by the scale factor: 1.5 inches * (1 foot / 1/4 inch) = 6 feet, and 2.25 inches * (1 foot / 1/4 inch) = 9 feet. Therefore, the bedroom is 6 feet by 9 feet in real life.

Determine the equation of the line through (-1,2) and perpendicular to the line 2x-3y+5=0

Answers

2x - 3y + 5 = 0
2x + 5 = 3y
2/3x + 5/3 = y...slope here is 2/3. A perpendicular line will have a negative reciprocal slope. All that means is " flip " the slope and change the sign. So our perpendicular line will have a slope of -3/2.

y = mx + b
slope(m) = -3/2
(-1,2)...x = -1 and y = 2
sub and find b, the y int
2 = -3/2(-1) + b
2 = 3/2 + b
2 - 3/2 = b
4/2 - 3/2 = b
1/2 = b

so ur perpendicular equation is : y = -3/2x + 1/2 or 3x + 2y = 1 or 3x + 2y - 1 = 0

A wall in Marcus's bedroom is 8 2/5 feet high and 16 2/3 feet long. If he paints 1/2 of the wall blue, how many square feet will be blue?

Answers

Approximately 12. 533... sq. Ft will be painted. (Sorry if if you wanted a fraction for the .533 portion haha, I was doing his off the top of my head)

Marcus's wall has an area of 140 square feet. If he paints half of it blue, 70 square feet will be blue.

To find the area of the wall, we multiply its height by its length:

[tex]\[ \text{Area of the wall} = \text{Height} \times \text{Length} \][/tex]

First, convert the mixed numbers to improper fractions:

- Height: [tex]\(8 \frac{2}{5} = \frac{42}{5}\) feet[/tex]

- Length: [tex]\(16 \frac{2}{3} = \frac{50}{3}\) feet[/tex]

Now, multiply:

[tex]\[ \text{Area} = \left( \frac{42}{5} \right) \times \left( \frac{50}{3} \right) \][/tex]

[tex]\[ \text{Area} = \frac{42 \times 50}{5 \times 3} = \frac{2100}{15} = 140 \text{ square feet} \][/tex]

If Marcus paints half of the wall blue, the area painted blue is:

[tex]\[ \text{Blue area} = \frac{1}{2} \times 140 = 70 \text{ square feet} \][/tex]

Therefore, 70 square feet of the wall will be blue.

A ball is dropped from a height of 5 ft and bounces to 60% of its previous height on each subsequent bounce. Which statement is true regarding the vertical distance the ball has traveled when it hits the ground for the fourth time?

A) 10.88 ft vertical distance traveled total
B) 16.76 ft vertical distance traveled total
C) 18.06 ft vertical distance traveled total
D) 21.76 ft vertical distance traveled total

Answers

Answer:

the answer is 16.76 ft option B

Step-by-step explanation:

The vertical distance the ball has traveled when it hits the ground for the fourth time is 16.76m.

What is the percentage?

The Percentage is the value per hundred.

Distance traveled by the ball when it hits the ground first time =5m

After the first hit, it bounces to 60% of its previous height

60% of 5m =3m

This means ball goes 3m up and then 3m down before hitting for the second time.

So, the vertical distance traveled by the ball till the second hit=5+3+3 =11m

After the second hit, it bounces to 60% of its previous height

60% of 3m =1.8m

This means ball goes 1.8m up and then 1.8m down before hitting for the third time.

So, the vertical distance traveled by the ball till the third hit=11+1.8+1.8 = 14.6m

After the third hit, it bounces to 60% of its previous height

60% of 1.8m =1.08m

This means ball goes 1.08m up and then 1.08m down.

So, the vertical distance traveled by the ball till the fourth hit=14.6+1.08+1.08 = 16.76m

Hence, the vertical distance the ball has traveled when it hits the ground for the fourth time is 16.76m.

The top base of a trapezoid is 18 inches and the bottom base is 22 inches. The height of the trapezoid is 8.5 inches. What is the area of the trapezoid

Answers

Final answer:

The area of the trapezoid with top base 18 inches, bottom base 22 inches, and height 8.5 inches is calculated using the formula (1/2) × (base1 + base2) × height, resulting in an area of 170 square inches.

Explanation:

To calculate the area of the trapezoid, you can use the formula for the area of a trapezoid, which is A = (1/2) × (base1 + base2) × height. In this case, the top base (base1) is 18 inches, the bottom base (base2) is 22 inches, and the height is 8.5 inches.

Using the formula, we get:

A = (1/2) × (18 inches + 22 inches) × 8.5 inches

A = (1/2) × 40 inches × 8.5 inches

A = 20 inches × 8.5 inches

A = 170 square inches

So, the area of the trapezoid is 170 square inches.

In this exercise we have to use the knowledge of cosine quadrants, like this:

Letter B

We have that the quadrant of the cosine is given by:

The two quadrants on the right are positive.The two quadrants on the left are negative.

So we know that:

[tex]cos (2\pi/3)[/tex] If it's in quadrant three, that's negative.

[tex]cos(5\pi/3)[/tex] If you're in quadrant four, that's positive.

See more about cosine at brainly.com/question/14290164

The correct answer is option B. Cosine is negative in the second quadrant and positive in the fourth quadrant.

To determine why [tex]cos(\frac{2\pi }{3})[/tex] is not equal to [tex]cos(\frac{5\pi }{3})[/tex], we can analyze the properties of cosine in different quadrants.

Reference Angles: The reference angle for both [tex]\frac{2\pi }{3}[/tex] and [tex]\frac{5\pi }{3}[/tex] is [tex]\frac{\pi }{3}[/tex].Quadrants: [tex]\frac{2\pi }{3}[/tex] is in the second quadrant, while [tex]\frac{5\pi }{3}[/tex] is in the fourth quadrant.Sign of Cosine: In the second quadrant, cosine is negative. In the fourth quadrant, cosine is positive.

Thus, because cosine is negative in the second quadrant and positive in the fourth quadrant, [tex]cos(\frac{2\pi }{3})[/tex] is not equal to [tex]cos(\frac{5\pi }{3})[/tex]. Therefore, the best explanation is: Cosine is negative in the second quadrant and positive in the fourth quadrant.

4. Lea's car travels on average of 30 miles per gallon of gas. If she spent $20.70 on gas for a 172.5 mile trip, what was the approximate cost of gas in dollars per gallon?

Answers

1. If 1 monster = 7.2 aliens and 1 monster = 15.5 oranges. So we can consider it as 7.2 aliens = 15.5 oranges. To find out how many oranges are equal to 1 alien we need to do this:
1 alien = 15.5 oranges/7.2;
1 alien = 2.15 oranges (approximately).

2. We have everything to solve this problem. So in a scaled drawing 1 mm = 150 m. => 1 m = 1/150 mm on the drawing. Then 1 m^2 = (1/150 mm)^2 =>
1 m^2 = 1/22500 mm^2.
So the answer is 1/22500 mm^2.

3. The formula of the length is S=V*t. where V - the speed and t = the time. We already know that V = 60 mph and t = 8 seconds. But the measure of the speed is miles per hour, so we need to convert 8 seconds to hours.
8 seconds = 8/60 minutes = (8/60)/60 hours;
Our solution looks like this:
1) S = 60 mph * (8/60)/60 hours;
2) S = 8/60 miles;
3) S = 0.13 miles;
Answer is 0.13 miles.

4. First let's find out how many gallons of gas she spent during her trip:
172.5/30 = 5.75 gal;

So the approximate cost of gas in dollars per gallon is 3.60$ per gallon.

What is the range of function y=√(-2cos^2x+3cosx-1)

Answers

Hello Friend,here is the solution for your question


so the given function is 
y= √(-2cos²x+3cosx-1)
 i.e = √[-2(cos²x-3/2+1/2)]
i.e = √[-2(cosx-3/4)²-9/16+1/2]
i.e. = √[-2(cos-3/4)²-1/16]
i.e. = √[1/8-3(cosx=3/4)²]-----------(1)

Now here  in this equation is this quantity :-
(cosx=3/4)²----------------(2)   is to it's minimum value then the whole equation 
i.e. = √[1/8-3(cosx=3/4)²] will be maximum and vice versa 


And we know that cosx-3/4 will be minimum if cosx=3/4
therefore put this in (1) we get 
(cosx=3/4)²=0    [ cosx=3/4]
hence the minimum value of the quantity (cosx=3/4)² is 0 

put this in equation (1) 
we get ,
i.e. = √[1/8-3(cosx=3/4)²]
   =√[1/8-3(0)]        [ because minimum value of of the quantity (cosx=3/4)² is 0 ]
     =√1/8
      =1/(2√2)

this is the maximum value now to find the minimum value 

since this is function of root so the value of y will always be ≥0 

hence the minimum value of the function y is 0 


Therefore, the range of function y is [0,1/(2√2)]

Mean = The sum of the data value ÷ Number of data

We would need the sum of 32 values to work out the mean score of 32 students. We will work out separately by finding the sum of scores of 12 students and sum of scores of 20 students

90 = Sum of data ÷ 12
Sum of data = 90×12 = 1080 scores

80 = Sum of data ÷ 20
Sum of data = 80×20 = 1600 scores

The sum of data of 32 students is 1080+1600 = 2680 scores
