Simplify 3/4 + 5/8 over 3/4 - 1/2
Setler79 [48]

Answer:

11/2

Step-by-step explanation:

\frac{\frac{3}{4} + \frac{5}{8}  }{\frac{3}{4} - \frac{1}{2} }

= 3/4 + 5/8 = 11/8 (take LCM)

3/4 - 1/2 = 1/4 (take LCM)

11/8 ÷ 1 /4

= 11/8 x 4

= 11/2

X+2/3=9/10 what does x equal
PtichkaEL [24]

Answer:

x = 7/30

Step-by-step explanation:

Identify the LCD; it is 30.  30 is the smallest number divisible by both 3 and 10.

Then we have:

(30/30)x + 20/30 = 27/30.

Clearing out the fractions, we get:

30x + 20 = 27, or 30x = 7

Dividing both sides of this result by 30 yields x = 7/30.

In ΔSTU, s = 50 inches, t = 58 inches and u=27 inches. Find the measure of ∠S to the nearest 10th of a degree.
Mandarinka [93]

Step-by-step explanation:

By Cosine rule, we have

s² = t² + u² - 2(t)(u)(cosS)

=> cosS = (t² + u² - s²)/2tu

=> cosS = (58² + 27² - 50²) / (2 * 58 * 27) = 0.5086.

Therefore S = cos^-1(0.5086) = 59.4° (1d.p.)
