To repeat, we need this:
15+c=17.50.

let's imagine a person who wants to save up for a book that costs 17.50. This person has already saved 15 dollars. how much more does he or she still need to save?
So now we solve:
15+c=17.50
subtract 15 from both sides
15+c=17.50
15-15+c=17.50-15
c=2.5

so the person needs to save 2.5 dollars more.

Nothing else is given, so for the two triangles to be congruent, the only possible proof is the ASA theorem.
first pairs of angles: 2x+7=x+21 => x=14
second pairs of angles: 8y-4=4y+28 =>y=8
The two triangles share the same side PR
Based on the Angle-Side-Angle Triangle Congruence theorem, these two triangles are congruent with x=14, y=8
(2x+7) +(8y-4) +Q=180 =>85

Consider that ΔDEF is similar to ΔGHI and the measure of ∠E is 58°. What is the measure of ∠H?
spayn [35]

Answer:

58 degrees

Step-by-step explanation:

If figures are similar to each other, it means that they have the same measures. Therefore, D has the same measure as G, E has the same measure as H, and F has the same measure as I.

Complete  Question

An online poll has a question that appears on the screen, and you simply click buttons to vote "Yes, " "No, " "Not sure, " or "Don't care." On a particular day, the results of a question were tallied. In all, 636 said "Yes, " another 595 said "No, " and the remaining 93 indicated that they were not sure.

a)

What is the sample size for this poll?

b)

Compute the percent of responses in each of the possible response categories. (Round your answers to two decimal places.)

c)

Discuss the poll in terms of the population and sample framework that we have studied in this chapter.

i)

This random sample of responses collects the opinions of a random group of users across all users of the Internet.

ii)

This voluntary response sample collects only the opinions of those that visit this site every day.

iii)

This random sample of responses collects the opinions of a random group of users of the particular site.

iv)

This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.

Answer:

a

   n  =  1324

b

  YES             y  = 48.03 \%

    NO             m  =44.94 \%

   NOT SURE  m  =7.02\%

c

The correct option is (iv)

Step-by-step explanation:

From the question we are told that

The voting options are "Yes, " "No, " "Not sure, " or "Don't care."

The number of people that said is Y =  636

The number of people that said No is N = 595

The number that indicated Not sure is S =  93

Generally the sample size is mathematically represented as

n  = Y  +  N  + S

=> n  =  636  +   595  + 93

=> n  =  1324

Generally the percentage of responses that was Yes is mathematically represented as

y  =  \frac{636}{ 1324}  * 100

=>     y  = 48.03 \%

Generally the percentage of responses that was No is mathematically represented as

m  =  \frac{595}{ 1324}  * 100

m  =44.94 \%

Generally the percentage of responses that was Not sure is mathematically represented as

s  =  \frac{93}{ 1324}  * 100

m  =7.02\%

This voluntary response sample collects only the opinions of those who visit this site and feel strongly enough to respond.

The volume of 2 spheres have a ratio of 27:125. what is the ratio of their radii
Citrus2011 [14]
The volume is scale factor³
Take the square root of the volume ratio

\sqrt{ \frac{27}{125} } which is 
\frac{ \sqrt{27} }{ \sqrt{125} }

\frac{3}{5}

The ratio of their radii is 3 : 5
