Answer:
20ft²
Step-by-step explanation:
Let the length = L
Let the width = W
Perimeter of a rectangle = 2L + 2W
Translating the word problem into an algebraic equation, we have;
L = 5W .......equation 1
2L + 2W = 24 ........equation 2
To find the width
Substituting equation 1 into equation 2, we have;
2(5W) + 2W = 24
10W + 2W = 24
12W = 24
W = 24/12
Width, W = 2 ft
To find the length;
Substituting the value of "W" into equation 1, we have;
L = 5W
L = 5*2
L = 10 ft
To find the area of the rectangle;
Area = LW
Area = 10*2
Area = 20 ft²
Therefore, the deck's area is 20 feet square.
Nebi has already typed 250 words. He then starts a timer and finds that he types 150 words in 3 minutes. If nebi types at a constant rate, write a linear equation to represent the number of words w that nebi types m minutes after starting the timer
Answer:
[tex]w=250+50m[/tex]
Step-by-step explanation:
Number words Nebi has typed = 250
t = Duration of typing = 3 minutes
Number of words typed in 3 minutes = 150
Rate of typing in 3 minutes
[tex]\dfrac{150}{3}=50\ \text{words/minute}[/tex]
So the linear equation representing the situation would be
[tex]w=250+50m[/tex]
Where
w = Number of words
m = Number of minutes after starting the timer
The linear equation to represent the number of words w that nebi types m minutes after starting the timer is w = 250 + 50m
Given:
Words already typed = 250 words.
Words typed in 3 minutes = 150 words
Words typed per minute = 150 words / 3 minutes
= 50 words per minute
w = Total words typed
m = number of minutes
The equation:
Total words typed = Words already typed + (Words typed per minute × number of minutes )
w = 250 + (50 × m)
w = 250 + 50m
Therefore, linear equation to represent the number of words w that nebi types m minutes after starting the timer is w = 250 + 50m

c) Parbati buys a mobile for Rs 6,300 and sells it to Laxmi at 15% profit. How much
does Laxmi pay for it?
Answer:
Rs. 7245
Step-by-step explanation:
Given parameters:
Cost price = Rs. 6300
Percentage profit = 15%
Unknown:
Selling price = ?
Solution:
If profit is made on a trade, the selling price is higher than the cost price.
Profit = Selling price - Cost price
To find the selling price simply;
Selling price =( 1 + [tex]\frac{15}{100}[/tex]) x cost price
Selling price = 1.15 x 6300 = Rs. 7245

A. 20.0 cm
B. 23.0 cm2
C. 25.0 cm2
D. 11.0 cm
Answer:
Answer is D, all you do is add the numbers
The perimeter of the figure is 20 cm.
The perimeter of the figure is the sum of the whole sides. When the whole sides of the figure is added the perimeter is known. Therefore,
perimeter = 5 cm + 3 cm + 1 cm + 2cm + 4cm + 5 cm
perimeter = 8 cm + 3cm + 9cm
perimeter = 20 cm

how would i slove for x??
Answer:
x=12
Step-by-step explanation:
First you need to find the 3rd angle.
180-118=x
x=62
Once you have that 3rd angle, set all the inside angles equal to 180
4x-6+5x+16+62=180 ---> set to 180
9x+72=180 -->combine like terms
9x=108 --> subtract 72 from both sides
x=12 -->divide both sides by 9

The Shredder, Inc. produces two types of paper shredders, home and office. The office model requires 6 hours to assembly and 2 finishing work units for finishing work, the home model requires 4 hours to assemble and 12 finishing work units for finishing. The maximum number of assembly hours available is 96 per day, and the maximum number of finishing hours available is 96 per day.
Let
x = the number of office model shredders produced per day and
y = the number of home model shredders produced per day.
Write the system of inequalities that represents the maximum number of shredders that can be produced in one day.
NOTE: 4 inequalities are expected.
Answer:
4y + 6x ≤ 96
12y + 2x ≤ 96
Step-by-step explanation:
Paper shredders produced :
Home :
Assembling time = 4 hours
Finishing work unit = 12
Office :
Assembling time = 6 hours
Finishing work unit = 2
Maximum number of assembly hours = 96 / day
Maximum number of finishing hours = 96/ day
Let
x = the number of office model shredders produced per day and
y = the number of home model shredders produced per day
(office Assembly hours x Number of office model) + (Assembly hours * number home models)
OFFICE MODEL:
Assembly operation :
Home + office ≤ 96
4y + 6x ≤ 96
Finishing operation :
Home + office ≤ 96
12y + 2x ≤ 96

What is the absolute value of the number indicated on the number line?
A. -1 3/7
B. 1 1/3
C. -1 1/3
D. 1 3/7
Answer:
1 and 1/3
Step-by-step explanation:
The absolute value means that you have a positive sign no matter what the value is. It is the distance in units from 0 on the number line to the point in question.
The number line is laid out in 1/6. Each tick is 1/6. Since the point is at 1 and 2/6, we have to reduce the fraction. In 2/6 you can divide the bottom and top by 2 to reduce the fraction.
2 divided by 2 = 1
6 divided by 2 = 3
Therefore the 2/6 reduces to 1/3
You already know you had a 1, so you add 1/3 and it is 1 1/3.
The life expectancy (M) in the United States is 85 with a standard deviation of 6 years. A random sample of 36 individuals is selected. What is the probability that the sample mean will be between 82.5 and 86 years?
Answer:
The probability that the sample mean will be between 82.5 and 86 years is 0.8351.
Step-by-step explanation:
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu\\[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]
The information provided is:
[tex]\mu=85\\\sigma=6\\n=36[/tex]
As the sample size is large enough the Central Limit Theorem can be used to approximate the sampling distribution of sample mean life expectancy (M) in the United States.
Compute the probability that the sample mean will be between 82.5 and 86 years as follows:
[tex]P(82.5<\bar X<86)=P(\frac{82.5-85}{6/\sqrt{36}}<\frac{\bar X-\mu_{\bar x}}{\sigma_{\bar x}}<\frac{86-85}{6/\sqrt{36}})\\\\=P(-2.5<Z<1)\\\\=P(Z<1)-P(Z<-2.5)\\\\=0.84134-0.00621\\\\=0.83513\\\\\approx 0.8351[/tex]
Thus, the probability that the sample mean will be between 82.5 and 86 years is 0.8351.
The probability that the sample mean will be between 82.5 and 86 years is 0.8351.
Standard deviation σ = 6
Sample size n =36
What is the central limit theorem?The central limit theorem (CLT) states that the distribution of sample means approximates a normal distribution as the sample size gets larger, regardless of the population's distribution.
Since the sample size is significant i.e. large, so the given scenario can be treated as normally distributed as per the central limit theorem.
So, the standard deviation of sample means = σ/√n
The probability that the sample mean will be between 82.5 and 86 years:
[tex]P(82.5 < X < 86) = P(\frac{82.5-85}{\frac{6}{\sqrt{36} } } < Z < \frac{86-85}{\frac{6}{\sqrt{36} } } )[/tex]
[tex]P(-2.5 < Z < 1)=P(Z < 1)-P(Z < 2.5)[/tex]
[tex]P(-2.5 < Z < 1) =0.8413-0.0062=0.8351[/tex]
Therefore, the probability that the sample mean will be between 82.5 and 86 years is 0.8351.
