Answer:

A1) 125

A2) 47.5%

B) 30

Step-by-step explanation:

Remember 'of' in this sentence means times(*). % shows a certain number/100.

a1) 48% 'of' what number is 60?

(let unknown number be x)

48/100 *x=60

Solve the equation, and the answer is x=125

a2) what percentage 'of' 120 is 57?

(let the unknown percentage be x)

(x/100)*120=57

x=47.5%

b) 24 students= 80% of the total number of students

1%=24/80

100% of the total number of students=30

So, there are total of 30 students

Answer:

x<-14

Step-by-step explanation:

Hello,

If we multiply by positive numbers it does not change the inequality, right?

So let's multiply by 10 both sides, it comes

2(4x+1)+10

I did not find a good way to show you here the number line. You need to basically take all numbers which are at the left of -14 on that line.

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

The principal of a high school e-mails a survey to all parents asking them to vote on the best time to have the PTA meeting. She
geniusboy [140]

Answer:

A

Step-by-step explanation:

The design of the survey leads to bias because a nonresponse error was made in this design. This type of sampling only represents those who answered the survey; it does not represent the entire population.

Only 56% of response were received this means the entire population did not participate in the survey only a chuck of them answered the survey. This can lead to a biased result, an assumption.

The answer is the second option: T<span>wo places left. 
 
 Therefore, the complete text is: "</span>To obtain the number of centimeters from a distance measured in meters, move the decimal point Two places left ".
<span> 
 The explanation is:
 
 1 meter has 100 centimeters,  then, if you have a distance of 45.55 centimeters and you want to know this value in meters, you need to divide it by 100 or, in others words, you need to </span>move the decimal point two places left:
<span> 
 =(45.55 centimeters)(1 meter/100 centimeters)
 =(45.55x1)/100

How would the fraction <img src="https://tex.z-dn.net/?f=%5Cfrac%7B7%7D%7B1-%5Csqrt%7B5%7D%20%7D" id="TexFormula1" title="\frac{
allsm [11]

Answer:

\frac{7 + 7 \sqrt{5} }{ - 4}

Step-by-step explanation:

We would multiply the fraction by its conjugate

( A conjugate is a expression that has the same integer or number values but have different signs) for example

5x + 2

and

5x - 2

ARE Conjugates.

The conjugate of

1 -  \sqrt{5}

is

1 +  \sqrt{5}

So this means we will multiply the expression by 1 plus sqr root of 5 on the numerator and denominator.

Our new numerator will be

7 \times (1 +  \sqrt{5} ) = 7 + 7 \sqrt{5}

We can apply the difference of squares for the denominator.

(x + y)(x - y) = x {}^{2}  -  {y}^{2}

So our denominator will be

1 - 5 =  - 4

So our rationalized fraction will be

\frac{7 + 7 \sqrt{5} }{ - 4}
