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.

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

Answer:

Step-by-step explanation:

This can be done with dimensional analysis.

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.

Answer:

7*5^10=68,359,375

Answer:

Step-by-step explanation:

Step one:

given data

initial charge =  $170 per hour

new charge= $136 per hour.

Required

% decrease

Step two:

% decrease = initial- new /inital charge

% decrease  = 170-136 /170*100

%  decrease = 34 /170*100

%  decrease = 0.2*100

% decrease = 20%

Answer:

x=266/41

Step-by-step explanation:

1ft 7in/3ft 5 in=x/40

or,12in+7in/36+5=x/40

or,19in/41in=x/40

or,19*40/41=x

•°•x=266/41

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:

7

Step-by-step explanation:

this can be written as an equation, which is 4x+2= 30

X = the number of friends

30= the total of stickers

4= the stickers each friend gets

2= the amount lan gets.

Now solve the equation, first subtract 2 on both sides, which is 28

4x=28 now divide both sides by 4, which will give you 7

x= 7, that means that answer is 7

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:

_24

step by step explanation

-2x-8×4=16

-2x-32=16

the -32 will go the other way and it will become positive

-2x=32+16

-2x=48

-2×/2=48/2

=-24

Answer:

8

Step-by-step explanation:

-2x-8y=16                   -2(8)-8(-4)=16

-2x-8(-4)=16                 -16+32=16

-2x+32=16                       16=16

-2x=-16

x=8

Have a great day and I hope this is correct

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

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:

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
