A housepainter mixed 5 gal of blue paint with every 9 gal of yellow paint in order to make a green paint. Which ratio of gallons of blue paint to gallons of yellow paint will make the same shade of green paint?

Answer:

[tex]Width = 20\ in[/tex]

[tex]Area = 400\ in^2[/tex]

Step-by-step explanation:

Given

See attachment for kite dimension

Required

Determine the width and the area

From the attachment, the height of the kite is:

[tex]Height = 31\ in + 9\ in[/tex]

[tex]Height = 40\ in[/tex]

The width which is half the height is:

[tex]Width = \frac{1}{2} * Height[/tex]

[tex]Width = \frac{1}{2} * 40\ in[/tex]

[tex]Width = 20\ in[/tex]

The area is:

[tex]Area = \frac{Height * Width}{2}[/tex]

[tex]Area = \frac{40\ in * 20\ in}{2}[/tex]

[tex]Area = 40\ in * 10\ in[/tex]

[tex]Area = 400\ in^2[/tex]

Answer:

3x + y = 20 and x - 2y = - 4

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

(a)

Given

3x + y = 17 ( subtract 3x from both sides )

y = - 3x + 17 ← in slope- intercept form

with slope m = - 3

Para;;el lines have equal slopes , then

y = - 3x + c ← is the partial equation

To find c substitute (4, 8) into the partial equation

8 = - 12 + c ⇒ c = 8 + 12 = 20

y = - 3x + 20 ← in slope- intercept form

Add 3x to both sides

3x + y = 20 ← in standard form

--------------------------------------------------------

(b)

Given

y + 2x = 13 ( subtract 2x from both sides )

y = - 2x + 13 ← in slope- intercept form

with slope m = - 2

Given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex] , then

y = [tex]\frac{1}{2}[/tex] x + c ← is the partial equation

To find c substitute (2, 3) into the partial equation

3 = 1 + c ⇒ c = 3 - 1 = 2

y = [tex]\frac{1}{2}[/tex] x + 2 ← in slope- intercept form

Multiply through by 2 to clear the fraction

2y = x + 4

x - 2y = - 4 ← in standard form

Answer: x < 4

Step-by-step explanation: To plot an inequality, find the number and go the way the sign is pointing.

In this problem...

The less than sign is pointing left, and the number is 4. We use an open circle because the sign is not equal to. If it was, we would of put a closed circle.

<, or > = Open circle (Not shaded)

≤, or ≥ = Closed circle (Shaded)

Answer:

280 miles

Step-by-step explanation:

It is given that :

Scale : 1.25 inches = 50 miles

In the map the distance between Piedmont and Tulsa is = 3.5 inches

So the actual distance between Piedmont and Tulsa in miles is given by :

  1.25 inches = 50 miles

So, 3.5 inches = [tex]$\frac{50 \times 3.5}{1.25}$[/tex] miles

                       = 140 miles.

So when we go from Piedmont to Tulsa, it is 140 miles and we go back from Tulsa to Piedmont, it is another 140 miles.

Therefore, total distance = 140 + 140

                                         = 280 miles

Answer:

The third graph is correct for the inequality 2x + 3y > -3

Step-by-step explanation:

The slope of the graph is –2/3.

The y-intercept is –1

The area above the dashed be line is shaded.

To verify, choose a coordinate in the shaded area, substitute the values for x and y. Calculate and check.

For example: (1,1)

2(1) + 3(1) > –3

2 + 3 > –3

5 > –3 True.

The graph that represents [tex]2x + 3y > -3[/tex] is (3)

The inequality is given as:

[tex]2x + 3y > -3[/tex]

Subtract 2x from both sides of the inequality

[tex]3y > -3 -2x[/tex]

Divide through by 3

[tex]y > -1 -\frac 23x[/tex]

Rewrite the inequality as follows:

[tex]y > -\frac 23x-1[/tex]

The above inequality means that:

Hence, the graph that represents [tex]2x + 3y > -3[/tex] is (3)

Answer:

I'm going to also give you how to get the answer... not just the answer.. you will need to know this for a test :/  so learn it  :P

Step-by-step explanation:

Sin(30)=12

to remember what Sin and Cos at those speacial angles in degrees are.. just use this Sin(degrees)

Sin(0) = 0/2         =0

Sin(30)= [tex]\sqrt{1}[/tex]/2         = 1/2

Sing(45) = [tex]\sqrt{2}[/tex]/2    = [tex]\sqrt{2}[/tex]/2

Sin(60)=[tex]\sqrt{3}[/tex]/2   = [tex]\sqrt{3}[/tex]/2

Sin(90)=[tex]\sqrt{4}[/tex]/2    = 1

Cos is exactly the same but counts backwards from 90°

Cos(90) = 0/2         =0

Cos(60) =  [tex]\sqrt{1}[/tex]/2         = 1/2

Cos(45) = [tex]\sqrt{2}[/tex]/2    = [tex]\sqrt{2}[/tex]/2

Cos(30) = [tex]\sqrt{3}[/tex]/2   = [tex]\sqrt{3}[/tex]/2

Cos(0) =[tex]\sqrt{4}[/tex]/2    = 1

note that the numerators just count from  0,1,2,3,4  , see?  you can remember sin and cos  now  :)   since you can count to 4   :P

Sin(30) =12

1/2 =12  while that statement makes no sense....  obviously 1/2 isn't equal to 12 but.. what's being said is that the angle of 30°  gives you a side that is 12 units long.  

so looking at what I wrote above.. which angle in degrees matches Sin when you look at Cos?  

Sin(30)= 1/2 and Cos(60) also = 1/2  huh

sooo  β = 60 °

got it?  :/

Answer:

269277

Step-by-step explanation:

Suppose a city with population 100,000 has been growing at at rate of 6% per year. If this rate continues, find the pouplation in 17 years

We solve using the formula for exponential growth

Pt = P( 1 + r)^t

When

P = Initial population = 100000

Pt = Population after time t = x

r = Growth rate = 6%

t = Time in years = 17

Hence:

Pt = 100000( 1 + 0.06)¹⁷

Pt = 100000( 1.06)¹⁷

Pt = 269277.27858

Approximately the population in 17 years = 269,277

Answer:

if it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth.

The increase after 10 years is (108%)^10 - 100% which is bigger than 80%.

If the value of a stock increases by 8% each year, then, that is not equal to the value of a stock increases 80% each decade.

The degree to which a value increases expressed in percent form is known as percentage increase.

Given that, The value of a stock increases by 8% each year.

a) If it increases 8% each year, the next year it's not 8% of the original, but 8% of the 108% and so forth, the incasement in percentage is an exponential increase not a linear increase, so we can't say that, the value of the stock increases 80% each decade

b) Since,  (108%)¹⁰ > 80%

Hence, the increase after 10 years is (108%)¹⁰, will be bigger than 80%.

Hence, If the value of a stock increases by 8% each year then, that is not equal to the value of a stock increases 80% each decade

Given that:

Base diameter = 8feets

Radius, r = 8/2 = 4 feets

Height h, = 20 feets

Volume of cylinder, V = πr²h

V = π * 4² * 20

V = π * 16 * 20

V = 1005.3096

V = 1005.3096 ft³

Answer:

A ∝ BCD or A = kBCD (k = constant ), then A varies jointly as B, C and D.

Step-by-step explanation:

The value of 'w' when x = 4 and y = 3 is, 40.

In its most basic form, a ratio is a comparison between two comparable quantities.

There are two types of proportions One is the direct proportion, whereby increasing one number by a constant k also increases the other quantity by the same constant k, and vice versa.

If one quantity is increased by a constant k, the other will decrease by the same constant k in the case of inverse proportion, and vice versa.

Given, The value of w varies jointly with x and y.

Let, w ∝ xy ⇒ w = kxy.

5 = k×(3/4)×2.

5 = (3/2)k.

k = 10/3.

Now, x = 4 and y = 3.

Therefore,

w = (10/3)×4×3.

w = 40.
