Solve for x 5(x+1)=4(x+8)

joja [24]

Answer:

x=27

Step-by-step explanation:

expanding the above expression we get

5x+5=4x+32

grouping numbers with coefficient of x at the left side and constant at the right side we get

5x-4x=32-5

x=27

The ratio of roosters to chickens is 2 to 8. If there are 5 roosters, how many chickens are there?

Aloiza [94]

Roosters to chickens is 2 to 8

That means where there are 2 roosters, there are 8 chickens.

Simplify the ratio 2:8
The ratio can be simplified to 1:4

So, for 1 rooster, there are 4 chickens.

Now, the question says that if there are 5 roosters, how many chickens will there be?

1 rooster to 4 chickens
5 roosters to ? chickens

We went from 1 rooster to 5 rooster. We multiplied by 5.
To find out how many chickens there are for 5 roosters, multiply 4 chickens by 5.

4 * 5 = 20

Where there are 5 roosters, there will be 20 chickens.

Another way to solve is as follows:

$\frac{2}{8} =\frac{5}{x}\\\\\sf{Cross~multiply}\\\\2x = 5\times 8\\\\2x = 40\\\\x = 20\\\\\boxed{\bf{x=20}}$

Your final answer is 20 chickens.<span />

Identify the center and radius for the following equation: (x+4)^2+(y-7)^2=4

ArbitrLikvidat [17]

This is the equation for a circle which without numbers looks like (x – h)^2 + (y – k)^2 = r^2

This means that the radius is the square root of what ever number the equation is equal to. Since in this case it is 4 the square root of 4 is 2

The center of the circle is baced off h and k. In order to find where each one of them go, you would do the opposit of the number that is with them. With this equation the opposit of 4 is -4 so it will go -4 in the x direction and the opposit of -7 is 7 so it would go 7 in the y direction

Radius: 2

Center: (-4,7)

A cone has a diameter of 9 inches and a height of 12 inches. Find the volume of the cone to the nearest tenth.

Vanyuwa [196]

1)
The formula for calculating the cone volume is:
$V = \frac{ \pi *r^2*h}{3}$

Data:
V (volume) = ?
h (height) → h = 12 in
d (diagonal) = 9 in , if: d = 2*r , soon: 9 = 2*r → 2r = 9 → r = 9/2 → r = 4.5 in
Use: $\pi \approx 3.14$

Solving:
$V = \frac{ \pi *r^2*h}{3}$
$V = \frac{ 3.14 *4.5^2*12}{3}$
$V = \frac{ 3.14 *20.25*12}{3}$
$V = \frac{763.02}{3}$
$\boxed{\boxed{V = 254.34\:in^3}}\end{array}}\qquad\quad\checkmark$

2)
The circle area formula is: $A = \pi * r^2$

Data:
A (area) = ?
d (diagonal) = 19 Km , if: d = 2*r , soon: 19 = 2*r → 2r = 19 → r = 19/2 → r = 9.5 Km
Use: $\pi \approx 3.14$

Solving:
$A = \pi * r^2$
$A = 3.14*9.5^2$
$A = 3.14*90.25$
$\boxed{\boxed{A = 283.385\:Km^2}}\end{array}}\qquad\quad\checkmark$

3) False, because it's the volume, the number of cubic units needed to fill a space.
