The length of a rectangle is 5 centimeters more than the width. The area of the rectangle is 36 centimeters. What is the length?
UNO [17]
We can represent the width as x and the length as x+5. Then we can make the area formula A=(x)*(x+5), plug in 36 for A, and solve for x

36=x^2+5x (distribute)
0=x^2+5x-36
0=(x+9)(x-4)
So x=-9 and 4 but dimensions can't be negative so x=4

So if the width is 4, then the length is 9 (4+5)

Hope this helps :)

A basket contains four apples, three peaches, and four pears. You randomly select and eat three pieces of fruit. The first piece
Artist 52 [7]
We have 4 apples, 3 peaches, and  4 pears.
The sample size is 11.

1st selection: apple
The probability of selecting an apple is 4/11.

2nd selection: peach
We now have a sample size of 10, which consists of 3 apples, 3 peaches, and 4 pears.
The probability of selecting a peach is 3/10.

3rd selection: peach
We now have a sample size of 9, which consists of 3 apples, 2 peaches, and 4 pears.
The probability of selecting a peach is 2/9.

Each selection was an independent event. Therefore the overall probability is
(4/11)*(3/10)*(2/9) = 4/165

Answer:
The probability of selecting an apple followed by 2 peaches is 4/165.
 This probability is equivalent to 0.024 or 2.4%.

(3a-3/4)*1/3 if a= 3/8 <br> PLS HELP!!
Lina20 [59]

Answer:

1/8

Step-by-step explanation:

Substitute a = 3/8 into the equation.

(3*\frac{3}{8} - \frac{3}{4} ) * \frac{1}{3} = (\frac{9}{8} - \frac{6}{8}) * \frac{1}{3}

=\frac{3}{8} * \frac{1}{3}  = \frac{1}{8}
