Only problem 6a. Can someone demonstrate how to do this so I can do the rest solo?

Answers

Answer 1

Answer:

as far as I can tell, is simply asking to write two more expressions, that are equivalent to the provided one, namely, grab the provided one and expand it, if you simplify the expanded version, you'd end up with the provided, for example

$\bf \boxed{6a.1}~\hfill \stackrel{changing}{\cfrac{29\cdot 3}{30\cdot 3}}\implies \stackrel{one}{\cfrac{87}{90}}~\hfill \stackrel{changing}{\cfrac{29\cdot 7}{30\cdot 7}}\implies \stackrel{t wo}{\cfrac{203}{210}}\n\n\n\boxed{6a.3}~\hfill \stackrel{ch anging}{\cfrac{15/ 3}{30/ 3}}\implies \stackrel{one}{\cfrac{5}{10}}~\hfill \stackrel{changing}{\cfrac{15/ 5}{30/ 5}}\implies \stackrel{two}{\cfrac{3}{6}}$

so let's do 6a1, 6a3 and 6a5.

$\bf \boxed{6a.1}~\hfill \stackrel{changing}{\cfrac{29\cdot 3}{30\cdot 3}}\implies \stackrel{one}{\cfrac{87}{90}}~\hfill \stackrel{changing}{\cfrac{29\cdot 7}{30\cdot 7}}\implies \stackrel{t wo}{\cfrac{203}{210}} \n\n\n \boxed{6a.3}~\hfill \stackrel{changing}{\cfrac{15/ 3}{30/ 3}}\implies \stackrel{one}{\cfrac{5}{10}}~\hfill \stackrel{changing}{\cfrac{15/ 5}{30/ 5}}\implies \stackrel{two}{\cfrac{3}{6}}$

$\bf \boxed{6a.5}~\hfill \stackrel{changing}{(9\cdot 10)/ (2\cdot 10)}\implies \stackrel{one}{90/ 20}~\hfill \stackrel{changing}{(9\cdot 70)/(2\cdot 70)}\implies \stackrel{two}{630/ 140}$

Please help!The formula d= sqrt 1.5h gives the distance (d) in miles you can see to the horizon from a height of h feet above the earth. To the nearest mile, how many miles can you see to the horizon from the top of the Empire State Building at 1250 feet?

Answers

Answer:

d (miles) = (sqrt 1.5) * height (feet)

d (miles) = 1.2247448714 * 1,250

d (miles) = 1,530.93 miles

What is the radius of a circle with an area of 78.5 square inches?

Answers

the radius is 5
Hope it helps

To answer this question we will need to use the formula, A = π r2. π also known as 3.14. Dividing both sides of this equation by π gives

A/π = r2

and hence if you know A, divide it by π and then take the square root to find r.

So, 78.5/3.14 and r2/3.14 which gives us 25=r2. Now do the square root. √25=r2 which is 5=r. So your final answer is Radius=5.

50 points!!!!!!A survey was conducted on the salaries of 20 randomly selected college graduates with degrees in the same subject area. Each person surveyed graduated within the same 5-year period. Ten of the people surveyed attended a private university, while the other 10 people surveyed attended a public university of roughly the same size.

Private Public
First Quartile $58,000 $35,000
Second Quartile (Median) $71,000 $42,000
Third Quartile $85,000 $54,000

Based on the samples, what generalization can be made?

The top ten percent of both the private and public university graduates surveyed earned more than $60,000 annually.

The interquartile range for public universities is $19,000 more than for private universities.

The top twenty-five percent of both the private and public university graduates surveyed earned more than $50,000 annually.

The interquartile range for private universities is $27,000 more than for public universities.

Answers

this is a complex problem invovlving multiplue variables.
fyi 58k=50,000 kstands for kilo means 1000
so
public vs private
58k vs 35k
71k vs 42k
85k vs 54k
this data is taken from 3 parts

each number is the middle number of each part

the first one:
top 10% eanes more than 60k
very likely becase none of the private university numbers list anything over 60k

second one:
interquartile is 19k more in public than for private
71k-42k=29k, not 19 so this is not likely

third one:
top 25% earnes more than 50k
this is more likely than the others because the data is from 1/3 and 1/3=33% and we are looking for 25% which is smaller and the numbers of the median is more than 50k so this is the most likely answer

fourth one
rangefor private is 27k more than for public
false since 72k>42k not the other way around

the answer is the third option (top 25%of privat and public reaned more than 50k per year)

The answer would be C
sorry it took long

What are 2 ways to solve 20=-5(-3+x)

Answers

1) First way:

$-5(-3+x) = 20$

=> $15 - 5x = 20$

=> $-5x = 20 -15$

=> $-5x = 5$

=> $x = 5/-5$

=> $x = -1$

2) Second way:

$-5(-3+x)=20$

=> $-3+x = 20/-5$

=> $- 3 + x = -4$

=> $x = -4 + 3$

=> $x = -1$

1) 20 = -5(-3+x)
20/-5 = -3 + x
-4 = -3 + x
-4 + 3 = x
x = -1
2)20 = -5(-3 + x)
20 = 15 - 5x
20 - 15 = - 5x
5 = -5x
5/-5 = x
x = -1

A circle has an area of 48in squared what is the radius of the circle use 3 for pie

Answers

The radius of the circle is 4 in. The formula for the area of a circle is $\pi r^(2)$ with r meaning radius. So if we use 3 for pi. Then $r^(2)$ is 16. So r is 4.
