Answer:

12

Step-by-step explanation:

194-50=144

144/12=12

Answer:

12 hours

Step-by-step explanation:

We can start with an equation: 12x+50 = 194 (x being number of hours)

solving gives 12x = 144

x = 144/12

x = 12

Step-by-step explanation:

S = (2 * pi * r^2) + (2 * pi * r * h)

S = (2 * pi * 4^2) + (2 * pi * 4 * 5)

S = (32 pi) + (40 pi) = 72pi = 226.08 ANS.

so the answer is 16+4i ^2

Answer:

15,539 gallons will remain after 192 days

Step-by-step explanation:

16,307 - 4x = y

Plug in 192 for x since that's how many days will have passed.

16,307 - 4(192) = y

4 x 192 = 768

Then, subtract 768 from 16,307 to see how many gallons will remain.

16,307 - 768 = 15,539

Answer:

15,539 gallons

Step-by-step explanation:

16,307 - 4x = y;

16,307 - 4(192) = y;

4 x 192 = 768;

16,307 - 768 = 15,539

Answer:

there is no solution

Step-by-step explanation:

When we solve it, the first step is [tex]-6x+1=7-6x[/tex].

-6x+6x is 0, so there is no solution

Answer:

There are no solutions.

Step-by-step explanation:

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

−2(3x)+1=7−6x

Step 1: Simplify both sides of the equation.

−2(3x)+1=7−6x

−6x+1=7+−6x

−6x+1=−6x+7

Step 2: Add 6x to both sides.

−6x+1+6x=−6x+7+6x

1=7

Step 3: Subtract 1 from both sides.

1−1=7−1

0=6

Answer:

The farm would need 235.2 liters daily for 4 horses, 8 sheep and 16 chickens.

Step-by-step explanation:

The daily consumption of water in the farm must be:

[tex]x = (4\,horses)\times \left(50\,\frac{L}{horse} \right) + (8\,sheep)\times \left(4\,\frac{L}{sheep} \right) + (16\,chickens)\times \left(0.2\,\frac{L}{chicken} \right)[/tex]

[tex]x = 235.2\,L[/tex]

The farm would need 235.2 liters daily for 4 horses, 8 sheep and 16 chickens.

Answer:

Step-by-step explanation:

We know that each backpacks is sold for $40.00.

The goal is to make at least $9,800 per week. With this information we can define the inequality

[tex]40x -10x \leq 9,800[/tex]

Where [tex]x[/tex] represents backpacks. Notice that this inequality is about profits, that's why we subtract the cost from the sell price, in this case, the profid margin is $30.00 per backpack, so

[tex]30x\leq 9,800[/tex]

Solving for [tex]x[/tex]

[tex]x\leq \frac{9800}{30}\\ x \leq 326.67[/tex]

Therefore, the factory needs to sell 327 packbacks to make at least 9,800 per week.

Answer:

17 feet

Step-by-step explanation:

I used the Pythagorean theorem to answer this question.

a^2 + b^2 = c^2

15^2 + 8^2 = c^2

225 + 64 = c^2

289=c^2

c^2=289

c=√289

c=17 feet

The length of the tip of the tree to the tip of it's shadow will be;

⇒ 17 feet

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

A 15 feet tree casts a shadow that is 8 feet long.

Now,

Since, A 15 feet tree casts a shadow that is 8 feet long.

Hence, The length of the tip of the tree to the tip of it's shadow = x feet

So, We get by using the Pythagoras theorem;

⇒ x² = 15² + 8²

⇒ x² = 225 + 64

⇒ x² = 289

⇒ x = √289

⇒ x = 17

Thus, The length of the tip of the tree to the tip of it's shadow will be;

⇒ 17 feet

Step-by-step explanation:

first start with the triangle

to find the base, subtract 8 from 16

to find height subtract 7 from 13

Answer:

A. One line

Step-by-step explanation:

Let rearrange the system of equations into explicit forms:

[tex]y = -2\cdot x - 5[/tex]

[tex]6\cdot x + 3\cdot y = -15[/tex]

[tex]3\cdot y = -6\cdot x - 15[/tex]

[tex]y = -2\cdot x - 5[/tex]

The second equation is identical to the first one, which means that there is just one line.

[tex]\frac{2}{3} (m+4) = \frac{1}{5} (3m+9)[/tex]

[tex]\frac{2m+8}{3} = \frac{3m+9}{5}[/tex]

10m + 40 = 9m + 27

10m - 9m = 27 - 40

m = -13

Answer:

m = - 13

Step-by-step explanation:

2/3 (m + 4) = 1/5 (3m+9)

2/3m + 8/3 = 3/5m + 9/5

2/3m - 3/5m = 9/5 - 8/3

10/15m - 9/15m = 27/15 - 40/15

1/15m = - 13/15

m = - 13/15 / 1/15

m = - 13/15 * 15

m = - 195/15

m = - 13

Then she checks out on the other bank, a big stone (point B) or something (which is not too far from her), she then goes along the bank to the point C so that BC is perpendicular with the bank.

If she can mark down the distance she walked AC and the angle BAC, then she can calculate the width of river (AB) by formula:

Answer:

The largest possible value of x is 2 + √8

Step-by-step explanation:

Given;

x² + y² = 4(x + y)

This is an equation of circle

x² + y² = 4x + 4y

x²- 4x + y² - 4y = 0

complete the square by taking half of coefficient of x and y, then add the squares to both sides;

x²- 4x + (-2)² + y² - 4y + (-2)² = (-2)² + (-2)²

factorize

(x - 2)² + (y - 2)² = √8

This circle has its center at  (2, 2)  with a radius of  √8

The largest x-value occurs at the right end of the circle = x value of the center plus the radius = 2 + √8
