For your trip to Austin you know you are going to travel 182 miles and your car can do that in 14 gallons. How far can your car travel on 8 gallons of gas?

Answers

First, you need to create a unit rate.
The car travels 182 miles on 14 gallons of gas.
To create a unit rate, you would have to divide 14 by 182.

182 mi 13 mi
———— = ———-
14 gal 1 gal

Then, you would need to multiply the numerator and denominator by 8 because the question is asking how far the car can travel on 8 gallons of gas.

13 mi x 8 104 mi
——— = ————
1 gal x 8 8 gal

So, your answer is the car travels 104 miles on 8 gallons of gas.

What is the slope of a line perpendicular to the line whose equation is
12x – 9y = 135. Fully reduce your answer.

Answers

Answer:

The slope is -9/12

Step-by-step explanation:

First find the slope of the given line:

12x - 9y = 135 → -9y = -12x + 135 → y = 12/9 - 15

The perpendicular slope is a slope that is the reciprocal and is the opposite charge of the given slope.

So the answer would be -9/12, which is 12/9 but flipped upside down and is negative.

Answers

Answer:

x=27/28

Step-by-step explanation:

Let's solve your equation step-by-step.

2x−14+x3=2

Step 1: Simplify both sides of the equation.

2x−14+x3=2

2x+−14+13x=2

(2x+13x)+(−14)=2(Combine Like Terms)

73x+−14=2

Step 2: Add 1/4 to both sides.

73x+−14+14=2+14

73x=94

Step 3: Multiply both sides by 3/7.

(37)*(73x)=(37)*(94)

x=27/28

Answer:

x=27/28

Ella purchased a game that was on sale for 12% off. The sales tax in her county is 6%. Let y represent the original price of the game. Write an expression that can be used to determine the final cost of the game.

A y − 0.12y

B 0.06(0.88y)

C 1.06(0.88y)

D y − 0.88y + 0.06y

Answers

Answer:

The expression that can be used to determine the final cost of the game is

1.06(0.88 y) ⇒ (C)

Step-by-step explanation:

If the price of an item is discounted, that mean its new price will be less its initial priceThe taxes on item, makes its new price greater than the initial price because tax is add

Let us solve the problem

∵ Ella purchased a game that was on sale for 12% off

→ That means the new price will (100% - 12%) of the initial price

∵ y represented the initial price of the game

→ Multiply y by (100% - 12%) to get the new price

∴ The new price = y (100% - 12%)

∴ The new price = y (88%)

→ Change 88% to normal number by divide it by 100

∴ The new price = y ([tex]\frac{88}{100}[/tex])

∴ The new price = 0.88 y

∵ The sales tax in her county is 6%

→ That means the final cost will be (100% + 6%) of 0.88 y

∴ The final cost = (100% + 6%) × (0.88 y)

∴ The final cost = 106% × (0.88 y)

→ Change 106% to normal number by divide it by 100

∴ The final cost = [tex]\frac{106}{100}[/tex] × (0.88 y)

∴ The final cost = 1.06(0.88 y)

The expression that can be used to determine the final cost of the game is 1.06(0.88 y)

Answer:

C. 1.06(0.88y)

Write the equation of the line in point-slope form that passes through the
given point with the given slope.
(-4, 3); m = 2

Answers

Answer:

y = 2x + 11

plug the values into y = mx+b:

3 = 2(-4) + b

solve, and you get

3 = -8 + b

b= 3+8 = 11

so, the equation is y = 2x+11

the answer is y= 2 x + 11

Write an equation of the line passing through point P(4,3) that is parallel to the line y = 12(x+4).

Answers

Answer:

y=12x-45

Step-by-step explanation:

First we want to get y=12(x+4) into Slope intercept form which is y=mx+b and we do that by multiplying 12 by x so we get 12x and multiplying 12 by 4 so we get 48.

Now we have:

y=12x+48

where the slope is 12.

Parallel lines have the same slope. so the line that goes through (4,3) will have the same slope.

Now that we have a slope and a point we want to write an equation in point-slope form: y-y1=m(x-x1)

Step 1 for this: y-3=12(x-4)

Step 2: we will distribute and solve for y so our answer is in slope intercept form.

Step 3: we now have the equation y-3=12x-48 after distributing now we add 3 to -3 so it cancels out and we add 3 to -48 and we get -45

Our answer is y=12x-45

Hope this helps!

5/6x-7/6=8 what Is the value of x If you could control the brain of a rat with your thoughts, what would you tell it to do? Perhaps you'd to tell it to go away. Or, if you were feeling mischievous, maybe you'd encourage it to creep into a sibling's bed or scurry across the floor of a crowded room. For proof-of-concept, scientists kept it simple. They asked human volunteers to move a rat's tail simply by thinking about ita feat they actually accomplished, with the aid of brain-to-brain interface technologies that transmitted electrical signals from the human to the rat brain.The experiment, which was reported recently in the journal PLoS ONE, was based on computer-to-brain interfacing with electroencephalography (EEG) in humans and focused brain ultrasound in rats. The humans conveyed their intention of moving the rats' tails by watching a computer display of a flickering strobe light. EEG captured the electrical activity associated with their thought processes while watching the strobe. When EEG signals became synchronized with signals from the visual stimuli, a spike in signal amplitude occurred, which was detected by the computer and subsequently relayed to the ultrasound electronics, triggering a burst of focused ultrasound to the rat brain. The burst, focused onto a specific area of the motor cortex in the brain of the anesthetized rat, ultimately produced a flick of the tail. (See a video of the experiment here.)The ability to control the thoughts of others is of special interest in the study of cognitive processes, and it could find applications in neurotherapy or even as a novel mode of communication in "brain-to-brain coupling." The practicality of these applications, however, remains to be explored.In the meantime, in highlighting the fine line between fiction and reality, the new study gives us plenty to think about.
