A flower bed surrounds the base of a tree. It is enclosed by stones to form a circle that measure 25.12 feet around. What is the

radius of the circle

4.

Using the diameter is easier.

D = C/ $\pi$

25.12/3.14 = 8

To find the radius from the diameter, divide by 2.

8/2 is 4.

What value(s) of x make the following equation true?<br> 2x - 6 = 3x + 1 - 2x - 7

omeli [17]

Answer:

x = 0

Step-by-step explanation:

2x−6=3x+1−2x−7

Step 1: Simplify both sides of the equation.

2x−6=3x+1−2x−7

2x+−6=3x+1+−2x+−7

2x−6=(3x+−2x)+(1+−7)(Here we Combine Like Terms)

2x−6=x+−6

2x−6=x−6

Step 2: Subtract x from both sides.

2x−6−x=x−6−x

x−6=−6

Step 3: Add 6 to both sides.

x−6+6=−6+6

x=0

Yeah I’m not good at this

levacccp [35]

For the given triangle, x = 5.1 cm and y = 6.1 cm.

Step-by-step explanation:

Step 1:

In the given triangle, the angle is 50°. It is given that the opposite side has a length of y cm and the adjacent side has a length of y cm. The hypotenuse of the triangle measures 8 cm.

To determine the length of the opposite side of the triangle, we use the sin of the given angle.

To determine the length of the adjacent side of the triangle, we use the cos of the given angle.

$sin \theta = \frac{oppositeside}{hypotenuse} , cos \theta = \frac{adjacentside}{hypotenuse}.$

Step 2:

In the given triangle,

The length of the opposite side = y cm,

The length of the adjacent side = x cm,

The length of the hypotenuse = 8 cm,

The angle of the triangle = 50°.

$sin \theta = \frac{oppositeside}{hypotenuse} , sin 50 = \frac{y}{8}.$

$y = 0.7660 (8) = 6.128.$

$cos \theta = \frac{adjacentside}{hypotenuse} , cos 50 = \frac{x}{8}.$

$x = 0.6427 (8) = 5.1416.$

So x = 5.1416 cm and y = 6.128 cm. Rounding these off to one decimal place, we get x = 5.1 cm and y = 6.1 cm.

F=f (1-v/s) change the subject of the formula into v

Artyom0805 [142]

Changing the subject of the formula into v means expressing v in terms of the other given variables. So given the original equation, as shown below, we can rearrange it so that we have v isolated on one side.

$F = f(1 - \frac{v}{s})$
$\frac{F}{f} = 1 - \frac{v}{s}$
$\frac{v}{s} = 1 - \frac{F}{f}$

To isolate v, we can just multiply s to both sides and come up with the final equation below.

$v = s(1 - \frac{F}{f})$

Thus, we have v = s(1 - F/f) with v as the subject of the formula.

Answer: v = s(1 - F/f)
