Area of deck= 2(20w)+4(w^2)+2(50w)d
456=2(20w)+4(w^2)+2(50w)

456=40w+4w^2+100w

456=4w^2+140w

114=w^2+35w

0=w^2+35w-114

find what 2 numbers multiply to get 114 and add to get 35 and factor

-3 and 38

0=(w-3)(w+38)

set each to zero

w-3=0

w=3

What is The simple interest earned on a deposit of $3000 at 6% for five years
Norma-Jean [14]

Answer: $900

Step-by-step explanation:

The simple interest is calculated using the formula:

(P × R × T)/100

where,

P = Principal = $3000

R = Rate = 6%

T = Time = 5 years

Simple Interest = (P × R × T)/100

= ($3000 × 6 × 5)/100

= 90000/100

= $900

Therefore, the simple interest is $900

vova2212 [387]

Step-by-step explanation:

First, let's find out how many tiles Mike needs.

Mike's kitchen is 75sqft, each tile covers 2.25sqft, so 75sqft/2.25sqft=33.3333...,

multiply that number by the cost per tile and round to the nearest hundredth.

Maria will take two books with her on a trip. Suppose that the probability that she will like book 1 is .6, the probabilitythats
morpeh [17]

Answer:

0.25 is the required probability.

Step-by-step explanation:

We are given the following in the question:

Probability that like book 1 = 0.6

P(1) = 0.6

Probability that like book 2 = 0.5

P(2) = 0.5

Probability that Maria likes both the books = 0.4

P(1\cap 2) = 0.4

We have to find the conditional probability that she will like book 2 given that she did not like book 1.

Thus, we have to evaluate:

P(2|1') = \dfrac{P(2\cap 1')}{P(1')} = \dfrac{P(2)-P(1\cap 2)}{1-P(1)}\\\\P(2|1') =\dfrac{0.5-0.4}{1-0.6} = 0.25

0.25 is the conditional probability that Maria will like book 2 given that she did not like book 1.
