Consider constructing a triangle, on paper, with angle measures of 90° and 52º.

What is the measure of the third angle?


40°

66°

90°

38°

Answers

Answer 1
38

Because a triangle adds up to 180 so if you have to angles you add them up and subtract that number from 180 and you get your answer


90 +52= 142

180-142=38
Answer 2
38°
A triangle= 180°
So if you add the 2 measurements given
90°+52°= 142°

So if you add
142+38= 180°

So thats will give you the answer of 180 so 38° is the answer

Given f(x)=0.25(6)x, find f−1(x).

Answers

Answer:

f−1(x) = [tex]\frac{4x}{6}[/tex]

Step-by-step explanation:

f(x) = 0.25(6)x, find f−1(x).

f(x) = 0.25(6)x

f(x) = [tex]\frac{6}{4}[/tex]x = [tex]\frac{6x}{4}[/tex]

f(x) = y

y =  [tex]\frac{6x}{4}[/tex]

Substitute y for an x & x for a y

x = [tex]\frac{6y}{4}[/tex]

Multiply both sides by 4

4( x ) = 4( [tex]\frac{6y}{4}[/tex] )

4x = 6y

Divide both sides by 6 to solve for y

[tex]\frac{4x}{6}[/tex] = y

y = [tex]\frac{4x}{6}[/tex]

so f−1(x) = [tex]\frac{4x}{6}[/tex]

craig likes to collect records. last year he had 10 records in his collection. now he has 15 records. what is the percent increase of his collection?

Answers

Answer:

His collection increased in a 20%.

Step-by-step explanation:

If 100% represents 10 records, what percentage would be for 12 records?

x = 12 100% / 10 = 120%

So, if we subtract 120% - 100%, it's gonna result in a difference of 20%, which means that 12 represents a 20% more, or his collection increased in a 20%.

A. y=25x+15;90

B. y=(25+15)+x;43

C. y=15x+25;70

D. y=(25+15)x;120


Explanation:

Answers

Answer:

15x+25 ; 70

Step-by-step explanation:

Given that,

Fernando cleans pools for the summer for $25 an hour plus a supply fee of $15.

Here, $25 is constant and $15 increases as the number of hour increase. For x hours, the cost for Fernando to clean a pool is given by :

y = 15x+25

For 3 hours,

y = 15(3)+25

= 45 + 25

= 70

So, the required option is (c) " 15x+25 ; 70 ".
