You use a microscope to look at bacteria that is 0.0034 millimeter long. The microscope magnifies the bacteria 430 times. How long does the bacteria appear to be when you look at it through the microscope?

Answers

Answer 1
ANSWER: 1.562
move the decimal point of 0.0034 to the right  to make it a whole number which is 34. Then multiply 34 times 430 which is 15,620.
move the decimal point  (which is at the end) 4 times to the left
the answer will be 1.562
Answer 2

Answer:

1.462 millimeters.

Step-by-step explanation:

You use a microscope to look at bacteria that is 0.0034 millimeter long.

The microscope magnifies the bacteria 430 times.

So the bacteria appears 430 times long through the microscope.

We will multiply the length of bacteria by 430.

The size of bacteria appear = 430 × 0.0034

                                              = 1.462 millimeters

The length of the bacteria would appear 1.462 millimeters through microscope.

Why is indirect compensation important to recruiting and retaining employees? (site 1)

Answers

Indirect compensation includes non-wage compensation to employees that are outside of their normal wages or salaries. These benefits may include health insurance, tuition funding, educational opportunities, daycare, vacation, as well as flexible work schedules. They are often not taxable, and provide important assets to companies looking to attract quality employees at different stages in their careers. A good example is health insurance. With the national debate on health care, quality affordable health insurance for employees and their families is a very important tool to attract employees.

Indirect compensations may encompass sales commisons, health, transport, accommodation allowances and so on which aren't included as part of their base salary.

Indirect compensations go a long way assisting employees in different aspects of their personal lives which may not be directly related to work.

A good indirect compensation which caters for transport, housing and medical expenditures seems way more beneficial than a huge base salary without allowances.

Also, indirect allowances such as commission encourages employees to put more effort into sales and marketing since it is based on percentage. Hence, the more they input, the more their earning.

Therefore, indirect allowances are of considerable benefit which is highly considered when choosing an employer.

Decorations for school dances take 1/5 of the student council's budget. Entertainment takes 3/10 of the budget. What fraction of the budget is left?

PLEASE INCLUDE STEPS!!!!!

Answers

Just subtract 1/5 from 3/10 and you’ll find your answer
we need to find out the total amount of budget used and then subtract from 1.

first, we need to find 1/5 + 3/10. in order to add these, we need to find a common denominator. because 5 divides 10 evenly, it would be easiest to use 10 as a denominator.

3/10 already has 10 in the denominator, so we don't have to touch it yet.

to get 1/5 to have a denominator of 10, we need to multiply both the top and bottom of the fraction by 2 (because 2 x 5 is 10). we can do this because we're multiplying by 2/2, which is equal to 1. multiplying by 1 does not change the value of the fraction.

1 x 2 = 2, and 5 x 2 = 10, so our new fraction equivalent to 1/5 is 2/10.

now, we can add 3/10 + 2/10. when you add fractions, you add the numerators and keep the common denominators. so 3/10 + 2/10 = (3+2)/10 = 5/10. so 5/10 of the budget has been used.

to find out what fraction is left, we subtract 1 - 5/10. 1 is equal to any number over itself (as we saw earlier with 2/2) so we're subtracting 10/10 - 5/10. this gets us to 5/10. so 5/10 of the budget is left. 5/10 can be reduced to 1/2 in simplest form, since you can divide both 5 and 10 by their greatest common factor, which is 5. so 1/2 of the budget is left.

Each stone in ally’s collection weighs about 4 ounces her collection weighs about 24 pounds in all about how many stones are in ally’s collection

Answers

96, 16 ounces = 1 lbs(pounds) so you times 24 by 16 and get 384 then you divide by 4 and you get 96.

The total number of stones in Ally's collection is A = 96

What is unit conversion?

In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.

The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.

A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.

Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.

Given data ,

Let the weight of the stone be = 4 ounces

And , let the weight of the collection be = 24 pounds

From the unit conversion , we get

1 pound = 16 ounces

So , 24 pounds = 16 x 24 = 384 ounces

And , the number of stones A = 384 ounces / weight of the stone

On simplifying , we get

The number of stones A = 384 / 4 = 96 stones

Hence , the number of stones is 96

a minor league baseball team plays 114 games in a season. if the team won 14 more than three times as many games as they lost, how many wins and losses did the team have?

Answers

Final answer:

To solve this problem, we can set up an equation. Let L be the number of games lost by the team. We are told that the team won 14 more than three times the number of games they lost, so the number of games won is 3L + 14. The team lost 25 games and won 89 games.

Explanation:

To solve this problem, we can set up an equation. Let L be the number of games lost by the team. We are told that the team won 14 more than three times the number of games they lost, so the number of games won is 3L + 14.

The total number of games played is the sum of the games won and the games lost, which is 114. So we have the equation:

(3L + 14) + L = 114

Simplifying the equation, we get:

4L + 14 = 114

Subtracting 14 from both sides, we have:

4L = 100

Dividing both sides by 4, we find that L = 25.

Therefore, the team lost 25 games. To find the number of wins, we can substitute the value of L into the equation we set up earlier:

3L + 14 = 3(25) + 14 = 75 + 14 = 89.

So the team had 89 wins and 25 losses.

A flower bed has the shape of a rectangle 21 feet long and 9 feet wide. What is its area in square yards?

Answers

21 times 9 which equals 189 feet and there are 3 feet in a yard so we do 189 divided by 3 which equals 63 so the answer is 63 square yards.

Brainlist please! :)

Answer:

21 square yards

Step-by-step explanation:

Let's remember that the formula of the area of a rectangle is A = L*W, where L is the length and W the width.

In this case, L = 21 feet and W = 9 feet.

Therefore, A = 21 feet * 9 feet = 189 square feet

We need the answer in square yards. We know that 1 feet equals 1/3 yard (1 feet = 1/3 yard)

As we need square yards, we just square the equation above.

1^2 square feet = (1/3) ^2 square yards

1 square feet = 1/9 square yards

The area is 189 square feet, so we just multiply by 189 on both sides to do the conversion to square yards.

189 square feet = 189*1/9 square yards

189 square feet = 21 square yards

The area of the flower bed is 21 square yards

definition of variables
A=company A
B=company B
h=number of hours used

[Part B]

By using the services of company A instead of company B to rent a truck for three hours you save 7 dollars.
company A:  A=3(3)+75 = 9+75= 84
company B:  B=2(3)+85 = 6+85 = 91
difference: 91-84= 7

Answer:

A)

Company A) would be y = 3x + 75

Company B) would be y = 2x + 85

company A                 company B

A = 3(5) + 75               B = 2(5) + 85

A = 15 + 75                 B = 10 + 85

A = 90                         B = 95

B)

Company A) so that would give us y = $90

Company B) and this would give us y = $95

C)

Company A- in 3 hours you would spend $84

Company B- in 3 hours you would spend $91

so you save $7 by using A instead of B

In a study of government financial aid for college​ students, it becomes necessary to estimate the percentage of​ full-time college students who earn a​ bachelor's degree in four years or less. Find the sample size needed to estimate that percentage. Use a 0.03 margin of error and use a confidence level of 95​%. Complete parts​ (a) through​ (c) below.


A.) Assume that nothing is known about the percentage to be estimated.

n=


B.)Assume prior studies have shown that about 55%
of​ full-time students earn​ bachelor's degrees in four years or less.

n=

c. Does the added knowledge in part​ (b) have much of an effect on the sample​ size?

Answers

The sample size needed to estimate the population proportion of a data within a margin of error, M, to a confidence level of 1 - α, with a previous population proportion estimate, p, is given by:

[tex]n=p(1-p)\left( \frac{z_{\alpha/2}}{M} \right)^2[/tex]

Part A:

Given a margin of error of 0.03 a confidence level of 95​%. Since we have know prior knowledge of the proportion estimate, we make use of the consevartive proportion estimate of 50% or 0.05.

[tex]z_{\alpha/2}[/tex] for 95% confidence is 1.96.

Therefore, the required sample size is given by

[tex]n=0.5(1-0.5)\left( \frac{1.96}{0.03} \right)^2 \\ \\ =0.5(0.5)(65.33)^2=0.25(4,268) \\ \\ =1,067.11[/tex]

Therefore, the required sample size is 1,068.



Part B:

Given that prior studies have shown that about 55% of​ full-time students earn​ bachelor's degrees in four years or less.

Thus, p becomes 55% = 0.55 and the required sample size is given by

[tex]n=0.55(1-0.55)\left( \frac{1.96}{0.03} \right)^2 \\ \\ =0.55(0.45)(65.33)^2=0.2475(4,268) \\ \\ =1,056.44[/tex]

Therefore, the required sample size is 1,057.



Part C:

When we dont know the additional infromation (i.e. in part A), we obtained that the required sample size is 1,068 but after we know the information our sample size becomes 1,057.

Though there is a difference between both sample sizes but the difference is not much and hence, the knowledge of the additional information does not have much of an effect on the sample size.

The required sample size is [tex]1,068[/tex]

A) Significance Level, [tex]\alpha = 0.05[/tex], Margin of Error,[tex]E=0.03[/tex]

The provided estimate of proportion p is, [tex]p=0.5[/tex]

The critical value for significance level, [tex]\alpha = 0.05[/tex] is [tex]1.96[/tex].

The following formula is used to compute the minimum sample size required to estimate the population proportion p within the required margin of error:

[tex]n>=p(1-p)\dfrac{Z_c}{E^2}^{2}[/tex]

Put Values , we get

[tex]n=0.5(1-0.5)\dfrac{1.96}{0.03^2}^{2}\\\\n=0.5(0.5)(65.33)^2\\\\n=0.25(4,268)[/tex]

[tex]n=1067.11[/tex]

Therefore, the sample size needed to satisfy the condition [tex]n>=1067.11[/tex] and it must be an integer number, we conclude that the minimum required sample size is [tex]n=1068[/tex]

Sample size, [tex]1068[/tex]

B) Significance Level, [tex]\alpha = 0.05[/tex], Margin of Error,[tex]E=0.03[/tex]

The provided estimate of proportion p is, [tex]p=0.55[/tex]

The critical value for significance level, [tex]\alpha = 0.05[/tex] is [tex]1.96[/tex].

The following formula is used to compute the minimum sample size required to estimate the population proportion p within the required margin of error:

[tex]n>=p(1-p)\dfrac{Z_c}{E^2}^{2}[/tex]

Put Values , we get

[tex]n=0.55(1-0.55)\dfrac{1.96}{0.03^2}^{2}\\\\n=0.55(0.45)(65.33)^2\\\\n=0.2475(4,268)[/tex]

[tex]n=1056.44[/tex]

Therefore, the sample size needed to satisfy the condition [tex]n>=1056.44[/tex] and it must be an integer number, we conclude that the minimum required sample size is [tex]n=1057[/tex]

Sample size, [tex]1057[/tex]

The sum of the digits of a two-digit number is 6.  If the digits are reversed, the difference between the new number and the original number is 18.  Find the original number

Answers

So:

There are only a few two numbers with a sum of 6. They are:

1 and 5
2 and 4
3 and 3

So basically, there are only three sets of possible two digit + reversed two digit numbers.

3 and 3, we can just eliminate that because it's the same thing both ways around.

1 and 5, the difference between 15 and 51 is way too much.

So therefore it would have to be the pairs of 2 and 4.

Since the difference between the new number and the original number is 18, the new number would have to be 42 and the old one 24.

So the original number would be 24.
suppose the one's digit is x, the ten's digit is y, then the number is 10y+x
when the digits are reversed, the new number is 10x+y
x+y=6 =>x=6-y
(10y+x)-(10x+y)=18
9y-9x=18
y-x=2
replace x with 6-y: y-(6-y)=2 =>y=4
x=6-4=2
so the original number is 42, the new number is 24
or the original number is 24, the new number is 42
