Consider a survey involving the cookie preferences of a sample of 1,214 adults. If 28% answered peanut butter" find the decimal and reduced fraction of that percentage
PRACTICE ANOTHER

Answers

Answer 1

The decimal fraction is 0.28 and reduced fraction is 7/25.

What is fraction?

In mathematics, the fraction is generally a term which define the small part of something or amount of something. A fraction has generally two parts a numerator and a denominator.

The general syntax for fraction is : [tex]\frac{x}{y}[/tex]

where, x is the numerator part

           y is the denominator part

The fraction has two types of notations:

Decimal notation : In the decimal notation of fraction the term is written as the decimal form of x / y. we generally try to reduce the decimal value upto the nearest tenth.Reduce notation: In the reduce notation the structure of term is x/y but in this we try to convert the fraction into smallest fraction form.

In the question given,

Total number of samples = 1214

Adults who answered peanut butter = 28%

Now, the decimal fraction  = 28 / 100 = 0.28

and, the reduce fraction  = 28/100 = (7)(4) / (25)(4) = 7/25

Hence, The decimal fraction is 0.28 and reduced fraction is 7/25.

mary robertson sells tires at a large car service center she earns 10 commission on the first $1000 15 on the next $2000 and 20 on sales of more than $3000 last

Answers

Her total commission was $560.

As 10% of the first $1,000, 15% of the next $2,000, and 20% of sales beyond $3,000 are commissions that she receives. She sold $3,400 worth of tires last week.

What does "total commission" mean?

The commission serves as a benefit or an inducement for the worker to close agreements so that the business can increase revenue and profits. The total commission is calculated by multiplying the total sales by the commission percentage.

After dividing the outcome by 100, multiply the sale price by the commission percentage. Perform the subsequent calculation: Each blue gadget costs $70. The salesman receives a 14% commission on each sale, or $9.80.

The percentage or fixed payment connected to a specific number of sales is referred to as a "commission rate." A commission, for instance, can be $30 or 6% of sales.

It is therefore $560.

b. how many employees will this company have during the 10th year?

c. After how many years will the company have 285 employees?

Answers

Answer:

a. 105 and 115 employees

b. 185 employees

c. 20 years

Step-by-step explanation:

The total of employees at any given year is y

x is the number of year

then y = 85 + 10x

a. 2nd year: y = 85 + 10(2) = 85 + 20 = 105

   3rd year: y = 85 + 10(3) = 85 + 30 = 115

b. 10th year: y = 85 + 10(10) = 85 + 100 = 185

c: if y = 285

285 = 85 + 10x

10x = 285 - 85

Find the missing angles x and y vertical/adjacent angles

Answers

Answer: x = 49 degrees,      y = 41 degrees

Step-by-step explanation:

Using supplementary angles, we know that x + y + 90 degrees = 180 degrees.

Using complimentary angles, we know that x + 41 degrees = 90 degrees, and x + y = 90 degrees.

Solving first for x,

x + 41 degrees = 90 degrees

x = 90 - 41 degrees

x = 49 degrees

Solving for y,

x + y = 90

Substituting 49 degrees in for x,

y + 49 degrees = 90 degrees

y = 90 - 49 degrees

y = 41 degrees

Jill records the temperature outside every hour for 4 hours. She finds that the temperature dropped by the same amount each hour. After 4 hours, she finds that the temperature dropped a total of 20∘F. She writes this number sentence.

What does the number sentence mean?
1. The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour.
2. The total number of drops, 20, divided by 4 hours equals 5 times per hour. The temperature dropped 5 times per hour.
3. The total drop in temperature, −20∘F, divided by 4∘F in the first hour, equals −5 drops. The temperature dropped 5 times.
4. The total number of hours, 20, divided by 4∘F equals 5 hours. The temperature dropped once every 5 hours.

Answers

The total drop in temperature, −20∘F, divided by 4 hours equals −5∘F per hour. The temperature dropped 5∘F each hour. (option 1)

What does the sentence mean?

Division is the process of grouping a number into equal parts using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operation.

If the total drop in temperature over 4 hours is −20∘F, in order to determine the temperature drop each hour, divide −20∘F by 4.

Drop each hour = −20∘F / 4 = −5∘F

The decay rate of a certain new cell phone is 0.333

For given question,

The average lifetime of a certain new cell phone is three years.

The manufacturer will replace any cell phone failing within two years of the date of purchase.

Also, the lifetime of these cell phones is known to follow an exponential distribution.

We need to find the decay rate.

We know that an exponential decay is the process of reducing an amount by a consistent percentage rate over a period of time.

since the average lifetime of a certain new cell phone is three years, the decay rate would be 1/3 = 0.333

The ideal height (in centimeters) of a mountain bike frame is about 10 centimeters less than two thirds of the bike riders leg length (in centimeters). Two riders leg length are 80 centimeters and 85 centimeters. To the nearest tenth of a centimeter, how much taller should the taller mountain bike frame be?

Answers

The taller mountain bike frame should be 3.4cm taller.

What should be the difference in the frames?

The equation that can be used to determine the ideal height of the mountain bike frame is:

Mountain bike frame : (2/3 x length of the bike rider's leg) - 10

Mountain bike frame when leg length is 80cm: (2/3 x 80) - 10 =53.3 - 10 = 43.3 cm

Mountain bike frame when leg length is 85cm: (2/3 x 85) - 10 = 56.7 - 10 = 46.7cm

Difference in mountain bike frame :46.7 cm - 43.3 cm = 3.4cm

The value of the variable x is 5 and the lengths of PL and LQ are 9 and 48, respectively.

How to find the value of a variable and the length of the line segments behind that variable

In this problem we find a line segment generated by points P and Q and in which a point L divides the line segment PQ in two sections: PL and LQ. In accordance with the statement, we have the following equations describing the geometric system:

PQ = PL + LQ              

PQ = PL + LQ

57 = (2 · x - 1) + (9 · x + 3)

Now we proceed to clear the variable x with the resulting equation:

57 = 11 · x + 2

55 = 11 · x

x = 5

And finally we find the length of each line segment:

PL = 2 · 5 - 1

PL = 9

LQ = 9 · 5 + 3

LQ = 48

The value of the variable x is 5 and the lengths of PL and LQ are 9 and 48, respectively.
