Answer:

<h3>The answer is 7/12.</h3>

Step-by-step explanation:

( \frac{2}{3}  -  \frac{1}{4} ) + ( \frac{1}{2}  \times  \frac{1}{3} )

Solve the terms in the bracket first

That's find the LCM of the ones which are subtracting

LCM of 3 and 4 is 12

That's

\frac{2}{3}  -  \frac{1}{4}  =  \frac{8 - 3}{12}  =  \frac{5}{12}

Next multiply the other terms in the other bracket

That's

\frac{1}{2}  \times  \frac{1}{3}   =  \frac{1}{6}

Add both results

That's

\frac{5}{12}  +  \frac{1}{6}

Find the LCM

The LCM is 12

We get the final answer as

\frac{5}{12}  +  \frac{1}{6}  =  \frac{5 + 2}{12}  =  \frac{7}{12}

Hope this helps you

The area of circle Z is 641 ft.
levacccp [35]

Answer:

I think  the radius would be 14.28ft

Step-by-step explanation:

Area of circle is pi r^2

Area of circle=641ft

so that means you have to divide 641/3.14 because the point of the question is finding the radius.

so 641/3.14=204.140127

then for the final step finding the square root which is about 14.28ft

that means the radius is 14.28ft.

Variable g is 8 more than variable w. Variable g is also 4 less than w. Which pair of equations best models the relationship bet
MrRa [10]
Given:
Variable g is 8 more than variable w. ⇒ g = w + 8
Variable g is also 4 less than w ⇒ g = w - 4

g = w + 8 or w = g - 8
g = w - 4 or w = g + 4

Akira and her puppy are both dressing up as superheroes for Halloween this year. Akira needs 1 yard of cloth for her cape. She a
Ahat [919]

The feet of cloth that she should buy for the capes is 4 feet.

<h3>How many feet should she buy?</h3>

The mathematical operations that would be used to determine the answer are addition and multiplication.

Addition is the process of summing two or more numbers together. Multiplication is the process of determining the product of two or more numbers.

The first step is to convert yard to feet

According to the unit of conversion : 1 yard = 3 feet

1 x 3 = 3 feet

The second step is to add the feet needed for Akira's cape with the foot needed for the puppy's cape

Total feet needed = 3 + 1 = 4 feet

your gym membership cost $33 per month after an initial membership fee. you paid a total of $228 after 6 months. writer an equat
grin007 [14]

Answer:

what i did was multiply 33*6 and got 198 and then 228-198 to find out that the initial fee was 30 dollars. then multiply 33*9+30 to get a  9-month total cost of $327

Step-by-step explanation:

cost = $33 per month + fee  

1.  c(m) = 33m + f

 33(6) + f = 228

198 + f = 228

f = $30 membership fee  

c(m) = 33m + 30

 2.  at 9 months:  33(9) + 30 = $327

hopefully this helps :)

have a nice day !!
