Trigonometric Functions:

$S\frac{O}{H} C\frac{A}{H} T\frac{O}{A}$

$Sine\frac{Opposite}{Hypotenuse} Cos\frac{Adjacent}{Hypotenuse} Tan\frac{Opposite}{Adjacent}$

You have the angle and the adjacent. You need to find the hypotenuse (PR). Therefore, you use cos.

$Cos(26)=\frac{13}{H}$

Rearrange the formula to find H (PR):

$H = \frac{13}{Cos(26)}$

Figure A is a scale image of Figure B. What is the value of x?

kari74 [83]

Hey there! :)

Answer:

x = 21 units.

Step-by-step explanation:

Since we know Figure A is just Figure B scaled, we can set up a proportion:

$\frac{45}{35}= \frac{27}{x}$

Cross multiply to solve for x:

45 · x = 35 · 27

45x = 945

Divide both sides by 45:

x = 21 units.

Of 10 test scores, eight are less than or equal to 82. What is the percentile rank of a test score of 82?

sdas [7]

Answer:

80%

Step-by-step explanation:

Percentile rank = (number of scores lower or equal to 82 / total number of scores) * 100%

Percentile = (8 / 10) * 100%

= 0.8 * 100%

= 80%

412 + 162 + 347 = 921. Because it is closer to 900 than 1,000, the answer is 900.
