Write the number in witch the digit 2 is one tenth the value of the digit 2 in 8.524.

1 answer:

4 0

Well the 2 in 8.524 would be 0.02 or 2 hundredths. Here's my explanation, the 8 is the whole number because it's before the decimal point, the 5 is the tenth or 0.5 and as you go further the number gets smaller so after the 5 is the 2 and that would be 2 hundredths or 0.02. So basically it's like going from tens, to hundreds, to thousands but only going in reverse order.

HELP! BRAINLIST COULD GET 50+ POINTS!!!

mestny [16]

Answer:

Step-by-step explanation:

well by rotating ΔABC by 60*(degrees) about A , such that in ΔA'B'C,B =C'

you can see that ΔAPP' is equilateral side length 1, meaning that <APP' =60*

you can also see that ΔCPP' is a 30- 60- 90 right angle also meaning that <CPP' =60* now,by adding the two together you see that < ACP =120* now you can also use the law of cosins and soooo

s2=(AP)2+(CP)2-2(AP)(CP)cos120*

s2=1+4-2(1)(2)cos120*

s2=5-4 (-1over2)

s= $\sqrt{x} 5+2\\$

so b is your answer hope this helped

Last year, a day care center had 120 children enrolled. This year, 144 children were enrolled at the day care center. Calculate

Stella [2.4K]

Number of children that enrolled in a day care center last year = 120
Number of children that enrolled in a day care center this year = 144
Difference in the number of children = 144 - 120
= 24
Percentage of increase = (24/120) * 100
= 20 percent.
From the above deduction, we can conclude that the correct option is option "B".

Korolek [52]

Answer:

0.509

Step-by-step explanation:

Given that a random sample of 1016 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?"

Of the 1016 adults surveyed, 517 indicated that televisions are a luxury they could do without.

To find out the point estimate of population proportion of adults in the country who believe that televisions are a luxury they could do without.

We find that point estimate is nothing but sample proportion

Sample proportion = favourably voters/total people surveyed

= $\frac{517}{1016} \\=0.5088\\=0.509$
