Answer:

Step-by-step explanation:

$(\frac{5}{4} + (-\frac{1}{3})) \div (\frac{5}{4} - (-\frac{1}{3}))\\\\\frac{\frac{5}{4}+\left(-\frac{1}{3}\right)}{\frac{5}{4}-\left(-\frac{1}{3}\right)}\\\\\mathrm{Remove\:parentheses}:\quad \left(-a\right)=-a,\:-\left(-a\right)=a\\=\frac{\frac{5}{4}-\frac{1}{3}}{\frac{5}{4}+\frac{1}{3}}\\\\\mathrm{Join}\:\frac{5}{4}+\frac{1}{3}:\quad \frac{19}{12}\\\mathrm{Join}\:\frac{5}{4}-\frac{1}{3}:\quad \frac{11}{12}\\\\=\frac{\frac{11}{12}}{\frac{19}{12}}\\\\=\frac{11\times\:12}{12\times \:19}$

= 11/19

How do you get the same base for the power

zhannawk [14.2K]

64 = 2 ^6
16 = 2^4 =

2^ 6*(2x+4) = 2^4 * 5x

6(2x+4) = 20x

10/3 x = 2x +4

4/3 x = 4

x = 3

you can also use logarithms like so

(2x+4)ln64 = 5x ln16

ln64/ln16 = 3/2

3/2 * 2x + 3/2 * 4 = 5x

3x + 6 = 5x

2x = 6

x = 3

See image for question. Please show workings and diagrams.

juin [17]

Answer:

a) 16.4 m, 101°
b) 6.22 m, 51 m²

Step-by-step explanation:

Find the measure of angle Q:

50° + (180° - 130°) = 100°

a) Find PR using the law of cosines:

PR = √(8² + 13² - 28*13*cos 100°) = 16.4 m (rounded)

Find ∠P using law of sines:

16.4/sin 100° = 13/ sin P
m∠P = arcsin (13 sin 100° / 16.4) = 51° (rounded)

The bearing of R from P is:

50° + 51° = 101°

Find the measure of h, the distance from Q to PR:

h/ PQ = sin P
h = PQ sin P
h = 8 sin 51° = 6.22 m

Find the area of ΔPQR:

A = 1/2PR*h
A = 1/2(16.4)(6.22) = 51 m²
