A rectangular picture is twice as long as it is wide. If the
area of the picture is 288 in^2, what are its dimensions?
The dimensions of the picture are_____ in long by_____ in wide.
Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
width is 12 inches. Plug that in to find length...
l=2×12
l=24

A company has 500 employees, and 60% of them have children. Suppose that we randomly select 4 of these
employees.
Which of the following would find the probability that exactly 3 of the 4 employees selected have children?
The probability that exactly 3 of the 4 employees selected will have children is given by binomial distribution formula ⁴C₃(0.60)³(0.40)
What is a Binomial Distribution?
The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.
The formula for Binomial Distribution is given by
P ( x ) = ⁿCₓ pˣq⁽¹⁻ˣ⁾
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Given data ,
Let the total number of employees be = 500
Now , the probability of success of selecting employees having children is given by p = 0.60
So , the value of q = 1 - p
q = 1 - 0.60
q = 0.40
So , The probability that exactly 3 of the 4 employees selected will have children is given by binomial distribution formula
where,
P ( x ) = ⁿCₓ pˣq⁽¹⁻ˣ⁾
where
n = number of trials
x = number of successes
p = probability of getting a success in one trial
q = probability of getting a failure in one trial
q = 1 - p
Substituting the values in the equation , we get
P ( x ) = ⁴C₃(0.60)³(0.40)
On simplifying the equation , we get
P ( x ) = 4 x 0.246 x 0.4
P ( x ) = 0.3456
Therefore , the value of P ( x ) is 0.3456
Hence , The probability that exactly 3 of the 4 employees selected will have children is given by binomial distribution formula ⁴C₃(0.60)³(0.40)

The length of a rectangular garden is 3 m greater than the width.the area of the garden is 70 m^2. Find the dimensions of the garden
Answer:
Step-by-step explanation:
A = L x W
so you know that the length is 3m longer than the width, so you could use a formula to represent that
w = L + 3
you then substitute the second equation into the first to solve for L
70 = L x (l +3)
70 = L^2 + 3l
you could then rearrange the formula and solve for l using the quadratic formula
0 = L^2 + 3l - 70
l = -3 +- (square root (3)^2 - 4(1)(70)) / 2(1)
l = -3 +- (square root 9 + 280) / 2
l = -3 +- (square root 289) / 2
l = -3 +- 17 / 2
then you solve for the two separate roots
l = -3 + 17 /2
l = 14 / 2
l = 7
or
l = -3 - 17 / 2
l = -20 / 2
l = -10
since a length cannot be negative, this root is not viable. therefore l = 7
to solve for w you would use
w = l + 3
w = 7 + 3
w = 10
hope this helps. :)))

Answer:
W = 10
L = 20
Step-by-step explanation:
2L + 2W = 60
L = 2W
Substitute for L in the first equation
2(2W) + 2W = 60
4W + 2W = 60
6W = 60
W = 10
Plug in W in the first equation
2L + 2(10) = 60
2L + 20 = 60
2L = 40
L = 20
Plug both answers in both equations to check
2(20) + 2(10) = 60
20 = 2 * 10

Fill in the number to find the sum . 2/10 + /100= 50/100 a. 30 b. 10 c. 28 d. 52
Answer:
2/10 + 30/100 = 50/100
Step-by-step explanation:
First, you want to multiply 2/10 by 10, to get the same common denominator in both numbers, you would get 20/100. Then, its pretty simple from there, you just add the number that gets you to 50, which is 30, 20 + 30 =50. I Hope This Helps :)
The required missing number is 30. So, the correct answer is (a) 30.
Arithmetic is a branch of mathematics that deals with the study of numbers, their properties, and their operations. It involves the basic operations of addition, subtraction, multiplication, and division.
Here,
To find the missing number, we can use the fact that 50/100 is equivalent to 1/2.
So, we need to find a number that, when added to 2/10, gives 1/2 as the sum.
We can write this as an equation:
2/10 + x/100 = 1/2
Multiplying both sides by 100 to eliminate the denominator, we get:
20 + x = 50
Subtracting 20 from both sides, we get:
x = 30
Therefore, the missing number is 30. So, the correct answer is (a) 30.

tance by a motorbike How many km did he
travelled ky motorbike?
Answer:
8 km by motorbike.
Step-by-step explanation:
The distance between itahari and Damak is 42 km.
Mr. Dhamala travelled 18.325 km by a bus / 15.675 km by a taxi and the remaining distance by a motorbike.
Let he covered x distance by motorbike. So,
Remaining distance = Total distance -(distance covered by bus + distance by taxi)
= 42 -(18.325 +15.675 )
= 42-34
= 8 km
So, he travelled 8 km by motorbike.

hannah is making a fleece tie blanket. it is 36 inches long. each tie will be 3/4 of an inch wide. how many times will she have
Proportionately, the number of times that Hannah will have to tie the blanket is 48 times.
What is proportion?Proportion is the relationship between two numerical values or variables. It shows the share or portion of a variable to the whole number.
Proportions are expressed as ratios, usually using fractions, decimals, or percentages.
Data and Calculations:The length of the fleece tie blanket = 36 inches
The width of each tie = 3/4 inches
The proportion of 3/4 inches to an inch = 0.75 (3/4)
The number of times to tie the blanket = 48 times (36/0.75)
Thus, the number of times that Hannah will tie the blanket is 48 times.
