If something was sold for $270 after it was reduced by 1/3 of the original price, what was the original price

Answer:

y=−34x+2.75

Step-by-step explanation:

Parallel lines have the same slope. Solve for the slope in the first line by converting the equation to slope-intercept form.

3x + 4y = 12

4y = –3x + 12

y = –(3/4)x + 3

slope = –3/4

We know that the second line will also have a slope of –3/4, and we are given the point (1,2). We can set up an equation in slope-intercept form and use these values to solve for the y-intercept.

y = mx + b

2 = –3/4(1) + b

2 = –3/4 + b

b = 2 + 3/4 = 2.75

Plug the y-intercept back into the equation to get our final answer.

y = –(3/4)x + 2.75

4 cm/s [ 1 m/100cm][3600 sec/1 hour]  

4 cm* 3600s / 100 cm = 4 m *3600 seconds / hr

144 m / hour. All the numbers and units cancel out.

2. $350

3a: 15 is half of 30, so knowing that means the answer is 50%

3b. 3 is 1/4 of 12 because 3x4 is 12, meaning that 3 is 25% of 12.

3c. 6 over 10 as a decimal is 0.6. Which as a percent is 60%

4. Noah's method does work because 20% x 5 is equal to 100% of a number.

Step-by-step explanation:

Umm.. i don't really have time to explain but

A^2+B^2=C^2

36^2+32^2=48.17

Answer:

A

Step-by-step explanation:

in order to find the answer take into mind what the question is asking for.

The equation has to pass the point (12,3) and has to be parallel to y=(4/3)x+5.

since the equations have to be parallel you can take out D since it has the reciprocal of the slope of the original equation.

You could also take out the negative equation C since the original one is not negative.

then you would have to graph the equations and would find that A is the answer because in order to have a point (12,3) you need to either start from the negative y-axis and ascend or from the positive axis and descend but B doesn't go down it goes up since it has a positive y value and has a positive slope. So in conclusion the answer would be A.

Answer:

The horizontal distance until the plane flies over the island is 2687ft

Step-by-step explanation:

An illustrative diagram of the scenario is shown in the attachment below.

P is the position of the plane, I indicates the position of the island and G is point on the ground such that /PG/ is perpendicular to the ground.

From the diagram, the horizontal distance from the plane to the island is x.

x = /IG/

In the diagram, consider triangle PIG which is a right angle triangle.

/PI/ is the hypotenuse

/IG/ is the opposite

and /GP/ is the adjacent.

From the formula,

[tex]tan\theta = \frac{opposite}{adjacent}\\[/tex]

∴ [tex]tan\theta = \frac{/IG/}{/GP/}\\[/tex]

[tex]tan\theta = \frac{x}{/GP/}\\[/tex]

∴ [tex]x = /GP/ tan\theta[/tex]

From the diagram

/GP/ = 7000 ft and [tex]\theta = 21[/tex]

∴ [tex]x = 7000 \times tan21\\[/tex]

[tex]x = 2687.05 ft[/tex]

[tex]x[/tex] ≅ 2687 ft

Hence, the horizontal distance until the plane flies over the island is 2687ft

If the function is translated using the rule (x + 1, y – 2), the resulting function will be g(x) = (x+1)² -2

Translation is a way of changing the position of a figure on an xy plane. Given the parent function

y = x²

If the function is translated using the rule (x + 1, y – 2), the resulting function will be g(x) = (x+1)² -2. The equivalent graph if the function is as shown  below.

The question is incomplete:

Keith and Michelle went out to dinner. The total cost of the meal, including the tip, came to $53.70. If the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?

Answer:

Each friend paid $22.05 without including the tip.

Step-by-step explanation:

Since you know the total cost of the meal including the tip and the value of the combined tip, you can subtract the amount of the tip from the total cost and divide the result by 2 as they spent an equal amount:

$53.70-$9.60=$44.1

$44.1/2=$22.05

According to this, the answer is that each friend paid $22.05 without including the tip.

Equation : (7x + 9) + (5x + 3) = 180°

The two lines, say, line a and b are parallel and line y is a transversal. The two angles are called supplementary angles.

_________________________________

To find the value of x, we need to solve the equation.

(7x + 9) + (5x + 3) = 180

7x + 9 + 5x + 3 = 180

(7x + 5x) + (9 + 3) = 180

12x + 12 = 180

12x = 180 - 12

12x = 168

x = 168/12

x = 84/6

x = 42/3

x = 14

Value of x: 14

_________________________________

First angle = 7x + 9

= 7×14 + 9

= 98 + 9

= 107

Second angle = 5x + 3

= 5×14 + 3

= 70 + 3

= 73

Angle measures: 107° & 73°

Answer:

$40

Step-by-step explanation:

Brian starts at $100, then loses 1/4th of the money,

100/4 = 25,

then you subtract 25 from 100, which gives you 75

With the remaining $75, he spends $15 on girl scout cookies,

75 - 15 = 60

He then has $60 remaining, but while walking home, loses 1/3 of the total amount.

60/3 = 20,

you then subtract 20 from 60, which gives you 40

Therefore, $40 is what is remaining.

Answer:

a = b = 40°

Step-by-step explanation:

∠ a and 140° are adjacent and are supplementary , thus

a = 180° - 140° = 40°

a and b are alternate angles and are congruent, thus

b = a = 40°

Answer:

b=40 okkkkllllllkkkkkkkkkkkkkkkkkkkkkllllllkkkk
