As per the given question, it is stated that the length of a rectangle is 5 m less than twice the breadth.
Assumption : Let us assume the length as "l" and width as "b". So,
[tex] \twoheadrightarrow \quad\sf{ Length =2(Width)-5} [/tex]
[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]
Also, we are given that the perimeter of the rectangle is 50 m. Basically, we need to apply here the formula of perimeter of rectangle which will act as a linear equation here.
[tex]\\ \twoheadrightarrow \quad\sf{ Perimeter_{(Rectangle)} = 2(\ell +b) } \\[/tex]
l denotes length b denotes breadth[tex]\\ \twoheadrightarrow \quad\sf{50= 2(2b-5+b)} \\[/tex]
[tex]\\ \twoheadrightarrow \quad\sf{50= 2(3b-5)} \\[/tex]
[tex]\\ \twoheadrightarrow \quad\sf{50= 6b - 10} \\[/tex]
[tex]\\ \twoheadrightarrow \quad\sf{50+10= 6b} \\[/tex]
[tex]\\ \twoheadrightarrow \quad\sf{60= 6b} \\[/tex]
[tex]\\ \twoheadrightarrow \quad\sf{\cancel{\dfrac{60}{6}}=b} \\[/tex]
[tex]\\ \twoheadrightarrow \quad\underline{\bf{10\; m = Width }} \\[/tex]
Now, finding the length. According to the question,
[tex] \twoheadrightarrow \quad\sf{ \ell=(2b-5) \; m} [/tex]
[tex] \twoheadrightarrow \quad\sf{ \ell=2(10)-5\; m} [/tex]
[tex] \twoheadrightarrow \quad\sf{ \ell=20-5\; m} [/tex]
[tex]\\ \twoheadrightarrow \quad\underline{\bf{15\; m = Length }} \\[/tex]
Therefore, length and breadth of the rectangle is 15 m and 10 m.

Find the area of this composite shape
11 cm
"11 cm
18 cm
6.5 cm
Answer:
166.5 cm squared
Step-by-step explanation:
Multiply 11x11 =121
Multiply 7x6.5 =45.5 (we get the 7 because 18-11=7)
Then we add 121 and 45.5 and get 166.5
The area of this composite shape is 166.5 square cm
Area of composite figuresComposite figures are figures that has more than 1 shape. The given figure is made up of two rectangles.
The area of the shape is given as shown below;
Area = (11*11) + (7 * 6.5)
Area = 121 + 45.5
Area = 166.5 square cm
Hence the area of this composite shape is 166.5 square cm

the admission fee at a small fair is $1.50 for children and $4.00 for adults. on a certain day, $5,050 is collected. if $1,00 adults attended the fair, write and solve linear equation to find the number of children that attended
Answer:
↓
Step-by-step explanation:
Ok here:
(5050-[100·4])÷1.50=k(kids)
(5050-400)÷1.50=k
3100=k
In a particular game, a fair die is tossed. If the number of spots showing is either four or five, you win $1. If the number of spots showing is six, you win $4. And if the number of spots showing is one, two, or three, you win nothing. You are going to play the game twice. The probability that you win at least $1 both times is
Answer:
The probability that you win at least $1 both times is 0.25 = 25%.
Step-by-step explanation:
For each game, there are only two possible outcomes. Either you win at least $1, or you do not. Games are independent. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Probability of winning at least $1 on a single game:
The die has 6 sides.
If it lands on 4, 5 or 6(either of the three sides), you win at least $1. So
[tex]p = \frac{1}{2} = 0.5[/tex]
You are going to play the game twice.
This means that [tex]n = 2[/tex]
The probability that you win at least $1 both times is
This is P(X = 2).
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{2,2}.(0.5)^{2}.(0.5)^{2} = 0.25[/tex]
The probability that you win at least $1 both times is 0.25 = 25%.
The probability that you win at least $ 1 both times is 25%.
Since in a particular game, a fair die is tossed, and if the number of spots showing is either four or five, you win $ 1, while if the number of spots showing is six, you win $ 4, and if the number of spots showing is one, two, or three, you win nothing, and you are going to play the game twice, to determine the probability that you win at least $ 1 both times the following calculation must be performed:
2/6 = 1 1/6 = 4 3/6 = 0 3/6 x 3/6 = X 0.25 = X
Therefore, the probability that you win at least $ 1 both times is 25%.

The club will base its decision about whether to increase the budget for the indoor rock climbing facility on
the analysis of its usage. The decision to increase the budget will depend on whether members are using
the indoor facility at least two times a week. Use the best measure of center for both of the original data
sets to determine whether the club should increase the budget. Assume there are four weeks in a month.
If you think the data is inconclusive, explain why.
Answer:
Yes, they should increase the budget, because both 8 (Manuel) and 9 (Gretchen) are at least 8. 8 times per month is equivalent to 2 times per week.

If you wash your car every 15 days & I wash mine every 20 days, in how many days will we be washing them on the same day?
Answer: 60 days
Step-by-step explanation:
To get the number of days that both of them will be washing the cars on thesame day, we have to find the lowest common multiple of 15 and 20. This will be:
Multiple of 15 = 15, 30, 45, 60, 75, 90
Multiples of 20 = 20, 40, 60, 80, 100
Lowest common multiple = 60
Therefore, they'll be Washing the car on thesame day on the 60th day.
