Let's assign the width to a variable, with that variable being x. the length is two times the width, so it would be 2x. the perimeter of a rectangle is length + length + width + width, so you would add 2x + 2x + x + x = 24 inches. combine like terms (x) to get 6x = 24. divide both sides by 6 to get x = 4. so the width (x) is 4, and the length (2x) is 8. the area of a rectangle is length times width, so multiply 4 * 8. that would get you 32 inches^2.

Show how to solve 6/15=2/?
Bas_tet [7]
<u></u>There are two way sof doing this question: 
 <em><u>1st solution  is : </u></em>
<em> </em><u><em>6/15 = 2/</em></u><u /><em><u>5</u>
</em>because 6/15 is divisible by 3 and it is done by this form : 
     3 X 2 = 6
       and
    3 X 5 = 15
<em><u>2nd solution is:
</u></em><u></u>6/15 = 2/?
here we suppose that the missing value is <em>x:
</em> 6/15 = 2/x
 
 you shift the denominators and then  multiply them by the their numerators:
 6 * x = 15 * 2
      6x = 30
 now you divide 6 on both sides:
<em> </em>6x/6 = 30/6
      <em><u>x = 5</u></em><em>

780 at 5.25 for 10 months what is the amount of simple interest
Annette [7]

Answer:

$814.13

Step-by-step explanation:

Recall that the simple interest formula is a=p(1+rt).

a= final amount (Unknown)

p=starting amount ($780)

r= interest rate (5.25= 0.0525%)

t=time in years (10 months =5/6 years)

Plug numbers into formula:

a=780(1+5.25*5/6)

Solve parenthesis first according to PEMDAS:

a=780(1.04375)

Multiply:

814.125

Round to nearest hundredth (cent):

$814.13

it would depend how much you actually used, but you would take the amount you used  and divide it by the total amount of yarn. so if the yarn was 4m long and you used 2m then it would be 2/4 which is 0.5 which is also 50%, so half the yarn was used.

you have a big bag of 17 marbles for our blue sticks are green 2 are red and the others are yellow what is the probability of dr
Alex Ar [27]

Answer:

  • 3/68

Step-by-step explanation:

<u>Given</u>

  • Total 17 marbles
  • 4 - blue marbles
  • 6 - green marbles
  • 2 - red marbles
  • The rest - yellow marbles

<u>Probability of drawing red first:</u>

  • P(red) = number of red / total number = 2/17

<u>Probability of drawing green second, without replacement:</u>

  • P(green) = number of green / number left in the bag = 6/16 = 3/8

<u>Probability of red and green in order:</u>

  • P = P(red)*P(green) = 2/17*3/8 = 3/68
