Anyone know the answer??

Answer:

100

Step-by-step explanation:

here we are solving for x

first plug in 100 for the ys in the equation

0.10x + 0.10(100) = 0.18(x + 100)

simplify

0.10x + 10 = 0.18x + 18

get x by itself

-8 = 0.08x

-100 = x

so the reasonable answer here would be 100

Answer:

8 hours

Step-by-step explanation:

We are given that

Casi traveled distance in 3 hours=135 miles

We have to find the time taken by Casi to drive 360 miles at the same speed using proportion .

Let time taken by Casi to drive 360 miles=x

We know that

Speed=[tex]\frac{Distance}{time}[/tex]

Using proportion

[tex]\frac{a}{b}=\frac{c}{d}[/tex]

[tex]\frac{135}{3}=\frac{36}{x}[/tex]

[tex]x=\frac{360\times 3}{135}[/tex]

[tex]x=8[/tex]

Hence, the time taken by Casi to drive 360 miles=8 hours

Answer:

3 sides

Step-by-step explanation:

sum of exterior angles for all polygons is 360°

sum of interior angles for a polygon can be found by using the formula:

(n - 2) · 180°  where 'n' is the number of sides

'sum of outer angles' = 360

'twice the sum of inner angles' = 2n

360 = 2n

n = 180

a three-sided polygon (triangle) has 180 degrees

Answer:

[tex]f(x) = 2x - 4 \\ f(x + 3) = 2(x + 3) - 4 \\ = 2x + 6 - 4 \\ = 2x + 2 \\ = 2(x + 1)[/tex]

Answer:

The length of fencing is 146 feet.

Step-by-step explanation:

The length of fencing is equal to the perimeter of the rectangle plus 8 times the width of the border between the edge of the pool and the fence. By Geometry, we find that the perimeter ([tex]p[/tex]), measured in feet, is equal to:

[tex]p = 2\cdot (w+f)+2\cdot (l+f)[/tex] (1)

Where:

[tex]w[/tex] - Width of the pool, measured in feet.

[tex]l[/tex] - Length of the pool, measured in feet.

[tex]f[/tex] - Width of the border, measured in feet.

If we know that [tex]w = 45\,ft[/tex], [tex]l = 18\,ft[/tex] and [tex]f = 5\,ft[/tex], then the length needed of fencing is:

[tex]p = 2\cdot (45\,ft+5\,ft)+2\cdot (18\,ft+5\,ft)[/tex]

[tex]p = 146\,ft[/tex]

The length of fencing is 146 feet.

Answer:

A) -3/4

B) 15 more minutes

C) 80 minutes

Step-by-step explanation:

A. rate of change = -3/4

B. 16 minutes

C. 1 hour 20 minutes

The slope is defined as the ratio of the vertical change between two points, the rise, to the horizontal change between the same two points, the run.

Given:

A) At first the tank contain 15 gallons of water.

After 4 minutes the tank contain 12 gallons of water.

So, rate of change

=12-15/4-0

=-3/4

=-3/4

B) now, Let x be the number of minutes will it take for the tank to drain completely.

So,

(3/4 gallons per minute) *x = 12 gallons

x = 12*4/3

x = 16 minutes

C) As, the tank has capacity of 75 gallons.

So, the tank of water is full when there is 10 gallons of water which is 60 gallons more.

Let 'y' be the number of minutes before Bob arrived when the water tank was completely full.

(3/4) (y) = 60

y = 60*4/3

y=  80 minutes

y= 1 hour 20 minutes

Answer:

fourth option

Step-by-step explanation:

Using the sine and cosine ratios in the right triangle and exact values

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] , cos60° = [tex]\frac{1}{2}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{4\sqrt{2} }[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 4[tex]\sqrt{6}[/tex] ( divide both sides by 2 )

x = 2[tex]\sqrt{6}[/tex]

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

cos60° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{y}{4\sqrt{2} }[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2y = 4[tex]\sqrt{2}[/tex] ( divide both sides by 2 )

y = 2[tex]\sqrt{2}[/tex]

Answer:

1.) [tex]\sqrt{13.341}[/tex]  ≈ 3.652

2.) I would say something about how the A in front of cos in the equation would change to 90, rather than stay 75 (in the equation for the step by step), but it would be easier to just use the Pythagorean theorem.

Step-by-step explanation:

I think we may have the same class so hopefully this helps:

1.) [tex]a^2 = b^2 + c^2 - 2bccosA[/tex] --> law of cosines formula.

   [tex]a^2 = 3^2 + 3^2 - 2(3)(3)cos(75)[/tex] --> plugged in numbers; when you draw the triangle, the included angle would be A, and the opposite side would be a. B and b, and C and c are opposite each other. In this case, a is the hypotenuse.

   [tex]a^2 = 18 - 18cos75[/tex] --> in between steps.

   [tex]a^2 = 13.341[/tex] --> more simplifying.

   [tex]a(hypotenuse) = \sqrt{13.341} or 3.652[/tex] --> answer

2.) This one is just an explanation: The 75 in the equation is the given angle, which is a. If this changes, it would just change in the equation too. And obviously, if it's 90 degrees, you can just use Pythagorean theorem a^2+b^2=c^2.

Good luck! :)

Answer:

x = 6.0

Step-by-step explanation:

As the given triangle is a right-angled triangle, we can use the trigonometric ratios to find the required length.

In the given triangle

Hypotenuse = 10

Perpendicular = x

Angle = 37°

As we know the value for perpendicular and hypotenuse, sine will be used.

[tex]sin\ 37 = \frac{Perpendicular}{Hypotenuse}\\sin\ 37 = \frac{x}{10}\\0.6018 = \frac{x}{10}\\x = 0.6018*10\\x = 6.018[/tex]

Rounding off to nearest tenth

x = 6.0

Hence,

x = 6.0

Pythons is the answer

Answer:

x = 111°

Step-by-step explanation:

Angles in a triangle add up to 180

180 - (29+82) = 69

Angles on a straight line add up to 180

180 - 69 = 111

Answer:

111°

Step-by-step explanation:

the sum of the outer angles of a triangle is alway 180

so 180-82-29= 69°

180-69= 111°

Answer:

Ounces of green paint needed = 13.8

Step-by-step explanation:

Blue paint : green paint = 25 : 115

how many ounces of green paint should she mix with 3 ounces of blue paint?

Let

Ounces of green paint needed = x

Blue paint : green paint = 3 : x

Equate both ratios

25 : 115 = 3 : x

25/115 = 3/x

25 * x = 115 * 3

25x = 345

x = 345/25

x = 13.8 ounces

Ounces of green paint needed = 13.8
