Answer:

a.12/13

Step-by-step explanation:

  • FORMULA: sine of an angle in a triangle is given by, \frac{opposite side's length}{length of the hypotenuse}
  • here, in the given triangle PQR, for angle 'p'

opposite side= QR

adjacent side= PQ

hypotenuse=PR

  • Therefore, sine of angle p= \frac{QR length}{PR length}  = \frac{12}{13}
  • Thus, by using the above given formula, the sine of angle p in the triangle PQR is 12/13.
  • hence, the trigonometric formulas as mentioned above should be remembered for sure to solve these type of problems

Jose and Gavin are reading the same book. At the beginning of the month, Jose was
Brums [2.3K]

Using linear functions, it is found that:

  • Jose's equation is: J = 17x + 10.
  • Gavin's equation is: G = 14x + 37.
  • They will be on the same page on the 9th day.

<h3>Linear function:</h3>

A <em>linear function</em> is modeled by:

y = mx + b

In which:

  • m is the slope, which is the rate of change.
  • b is the y-intercept, which is the value of y when x = 0.

Jose:

  • Initially, he was on page 10, hence b = 10.
  • He reads 17 pages per day, hence m = 17.
  • Hence, Jose's equation is: J = 17x + 10.

Gavin:

  • Initially, he was on page 37, hence b = 37.
  • He reads 14 pages per day, hence m = 14.
  • Hence, Gavin's equation is: G = 14x + 37.

The day they will both be on the same page is x for which:

J = G

Hence:

17x + 10 = 14x + 37

3x = 27

x = \frac{27}{3}

x = 9

They will be on the same page on the 9th day.

PLEASE HELP 7TH GRADE MATH
kaheart [24]

Answer:

Step-by-step explanation:

Number 5 is L because you have 18 coins but you only want to find the probability of the pennies. So take 3/18 and simplify to 1/6 by dividing both the numerator and the denominator by 3.

Number 6 can be (-6x - 3), just use the distributive property on the original expression.
