Answer/Step-by-step Explanation:

Circumference of a circular object = πd

Where,

π = 3.14,

d = diameter

Circumference of hula pop with diameter of 35 in:

Circumference = πd = 3.14*35 = 109.9 in

Diameter of circular pond with a circumference of 556 ft:

556 = 3.14*d

Divide both sides by 3.14

556/3.14 = d

177.07 = d

d ≈ 117 in

Circumference of magnifying glass with a diameter of 5.2 in:

Circumference = πd = 3.14*5.2 = 16.328 ≈ 16.4 cm

Diameter of car tire with a circumference of 71.6 in:

71.6 = 3.14*d

Divide both sides by 3.14

71.6/3.14 = d

22.80 = d

d ≈ 22.8 in

Solve the equation y. 6=2(y+2)

atroni [7]

Answer:

y = 1

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6-(2*(y+2))=0

Step by step solution :

Equation at the end of step 1 :

6 - 2 • (y + 2) = 0

Pulling out like terms :

3.1 Pull out like factors :

2 - 2y = -2 • (y - 1)

Equation at the end of step 3 :

-2 • (y - 1) = 0

Equations which are never true :

4.1 Solve : -2 = 0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

4.2 Solve : y-1 = 0

Add 1 to both sides of the equation :

y = 1

One solution was found :

y = 1

Statewide, there are 20 full-time employees to every 3 part-time employees. If there are 250,000 full-time employees, how many p

pickupchik [31]

Divide total full time employees by 20 to find how many groups of 20 there are, then multiply that number by 3 to find total part time employees:

250,000 / 20 = 12,500

12,500 x 3 = 37,500 part time employees.

1/4x – 2 = 3/8 Please show an equation and work. :)

Julli [10]

1/4x - 2 = 3/8

First, to start solving this, we can rearrange our fraction. Let's take 1/4x and change it to x/4. Why? Well, a variable can also be considered as the number 1.
$\frac{x}{4} - 2 = \frac{3}{8}$

Second, now we can continue solving for our variable (x). Let's add 2 to each side.
$\frac{x}{4} = \frac{3}{8} + 2$

Third, let's simplify 3/8 + 2. (3/8 + 2 = 2.375 =19/8)
$\frac{x}{4} = \frac{19}{8}$

Fourth, continue trying to get the variable by itself. Multiply each side by 4.
$x = \frac{19}{8} \times 4$

Fifth, let's simplify 19/8 × 4. This is simple. Leave the denominator be and just do 19 × 4, which equals 76.
$x = \frac{76}{8}$

Sixth, our final step is to simplify our fraction. To do so, we will need to list the factors of the numerator and denominator and find the greatest common factor (GCF).

Factors of 76: 1, 2, 4, 19, 38, 76
Factors of 8: 1, 2, 4, 8

Since 4 is our first common factor, it is considered our GCF.

Seventh, now let's divide. Divide both the numerator and denominator by the GCF (4) to create our new simplified fraction.
$76 \div 4 = 19 \\ 8 \div 4 = 2$

Answer in fraction form: $\fbox {x = 19/2}$
Answer in decimal form: $\fbox {x = 9.5}$
