Answer:

c=20.5 or 41/2

Step-by-step explanation:

c- 1/2 + 16=36

Make C the subject

c=36-16+1/2

c=20+1/2

Using LCM

c=(40+1)/2

c=41/2

c=20.5

To check if we are correct, we substitute c with 41/2. and then both sides of the equation must be equal

c- 1/2 + 16=36

41/2-1/2+16=36

20+16=36

36=36

What is the best approximation for the perimeter of a semicircle with a diameter of 64 meters?

OverLord2011 [107]

By definition, the perimeter of a semicircle is given by:
 $P = ( \pi ) * (r) + d$
 Where,
d: diameter of the semicircle
r: radius of the semicircle.
The radius of the semicircle is given by:
 $r = d / 2 
$
 Where,
d: diameter of the semicircle
Substituting values:
 $r = 64/2 

r = 32 m$ 
Then, the perimeter is:
 $P = (3.14) * (32) + 64 

P = 
 164.48 m$ 
Answer:
The perimeter of the semicurcle is given by:
P = 164.48 m

Muriel can do the laundry in 3 hours working alone. Rea has more experience and can do the laundry in 2 hours working alone. How

vagabundo [1.1K]

Here we have a problem of rates of work, where we want to find the rate at which two people would work together, so we can find the time it takes to complete a given job when these two work together..

We will find that they need to work for 6/5 hours to do the laundry together.

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

We know that:

Muriel can do the laundry in 3 hours.
Rea can do the laundry in 2 hours.

Then we can define:

M = rate at which Muriel works = 1/3h
R = rate at which Rea works = 1/2h

Where the rates are computed as the quotient between 1 (1 total laundry completed) and the amount of time it takes to do it.

If they work together, the rate just adds up, so we will have:

rate = (M + R) = 1/3h + 1/2h

Now we need to write that as a single fraction, so we get:

rate = 1/3h + 1/2h = 2/6h + 3/6h = 5/6h

Now we can write an equation of the form:

rate*time = 1

Where the 1 again, means "one complete laundry done".

Then we have:

(5/6h)*T = 1

T = (6/5)h

This means that they need to work for (6/5) hours to do the laundry together.

maria [59]

The inequality will be:

$x\geq 200$

Step-by-step explanation:

We need to write the inequality for the condition:

To get the 10% discount, a shopper must spend at least $200.Use d to represent the spending (in dollars) of a shopper who gets the discount.

Solution:

A person will get 10% discount if he spends $200 or more

Let x represents the amount that the shoppers will spend on shopping.

at least spend means the shoppers should spend $200 or more on the shopping to get the discount.

The inequality will be:

$x\geq 200$
