Answer: He worked 40 hours that week.

Step-by-step explanation:

Given : The owner of an automotive shop devotes 90% of his workweek to supervising, sales and accounting tasks. In one week.

Let x = Number of hours he work in a week.

then, Hours for supervising, sales and accounting tasks = 90% of x

As per given ,

[tex]90\%\ of \ x= 36\\\\\Rightarrow\ 0.90x=36\\\\\Rightarrow\ x=\dfrac{36}{0.9}=\dfrac{360}{9}\\\\\Rightarrow\ x=40[/tex]

Hence, he worked 40 hours that week.

======================================================

Explanation:

A counter-example could be something like 2/3 which is rational, but not an integer since 2/3 = 0.67  has a fractional or decimal portion to it. An integer is one where its a positive or negative whole number. Zero is also an integer.

Any rational number is a ratio or fraction of two integers. Zero is not allowed in the denominator. Any integer is a rational number since x = x/1, where x is any integer. For example, 9 = 9/1.

Answer:

False

Step-by-step explanation:

Rational numbers include all integers, fractions, or terminating and repeating decimals.

Answer:

33% or 33.3% or 33.33%

Step-by-step explanation:

Answer:

2.4

Step-by-step explanation:

The formula you would use is: A = P(1 + rt)

P is the principal which is $270

r is the interest rate

t is the time in years but we have 11 days so 11/360

A is $19.8

let's put the values in the formula

$289.9= $270(1 + r*(11/360))

you will find the r is 2.4

Answer:

7.03%

Step-by-step explanation:

The percentage of the life time cost which was the interest is; Choice B; 13.21%

Since, the APR is compounded monthly at an Annual percentage rate, APR of 11.27%, it follows that;

Hence, the total amount to be paid over the two and half years is; A = $1017.38.

Hence, the interest is given as;

The cost of electricity bill at $0.36 per day, (Assuming that there were two leap years over the period).

Hence, the lifetime cost of the laptop is; $789.12 + $1017.38 = $1806.5.

Ultimately, the required percentage is;

Answer:

84

Step-by-step explanation:

To get from 4 to 12, you multiply with 3.

Everything is 3 times as big in the larger rectangle.

This includes the perimeter.

Example:

small rect 4x10, perimeter 4+4+10+10 = 28

large rect 12x30, perimeter 12+12+30+30 = 84

but also 28x3 = 84

The perimeter of the larger rectangle is 84.

Its the sum of length of the sides used to made the given figure.

We are given that length of small rectangle is 4 and the length of the big

rectangle is 12. If the perimeter of the smaller rectangle is 28,

The small rectangle

length = 4

perimeter = 28

The big rectangle

length = 12

perimeter = ?

The small rectangle perimeter = 2l + 2w

28 = 2 * 4 + 2 w

28 - 8 = 2w

20 / 2 = w

10 = w

The big rectangle perimeter;

4 w = 10 * 12

w = 120 / 4 = 30

Perimeter = 2*12 + 2*30

= 24 + 60 = 84

The perimeter of the big rectangle is 84.

Answer:

0.986

Step-by-step explanation:

Probability of at least one being vac = 1 - Probability of all 5 not vac

1 - (1-0.57)^5 = 1 - (0.43^5) = 1 - 0.014 = 0.986

The probability that at least one of the five randomly chosen individuals had received a vaccination is around 0.956, or 95.6%.

Given that in a population, 57% people were vaccinated.

5 people are randomly selected, we need to find the probability that at least one of them has been vaccinated.

To calculate the probability that at least one of the five randomly selected people has been vaccinated, we can use the complementary probability approach.

The probability that none of the five people have been vaccinated is equal to the complement of the probability that at least one of them has been vaccinated.

So, let's calculate the probability of none of them being vaccinated and subtract it from 1 to find the desired probability.

The probability that a randomly selected person has not been vaccinated is 1 - 0.57 = 0.43 or 43%.

Since the selection of each person is independent, the probability that all five of them have not been vaccinated is:

P(Not Vaccinated) = 0.43⁵ = 0.043855

The probability that at least one of them has been vaccinated is the complement of the above probability:

P(at least one vaccinated) = 1 - P(not vaccinated)

= 1 - 0.043855 = 0.956145

Therefore, the probability that at least one of the five randomly selected people has been vaccinated is approximately 0.956 or 95.6%.

x = amount (kg) of 25% coper alloy

y = amount (also kg) of 70% copper alloy

Each kilogram of the 25% alloy contains 0.25 kg of copper, while each kilogram of the 70% alloy contains 0.7 kg of copper. When combined, the metalworker ends up with (x + y) kg of an alloy that should consist of 52% copper, so that it contains 0.52 (x + y) kg of copper.

The metalworker wants to make 50 kg of this new alloy, so that

x + y = 50

of which 52%, 0.52 (50 kg) = 26 kg, is copper, so

0.25x + 0.7y = 26

Solve for y in terms of x :

y = 50 - x

Substitute this into the other equation and solve for x :

0.25x + 0.7 (50 - x) = 26

0.25x + 35 - 0.7x = 26

9 = 0.45x

x = 20   →  y = 30
