Answer:

Angle A = 68 Angle B = 22 AC = 15.8

Step-by-step explanation:

sin(x) = Opposite/Hypotenuse

sin(A) = 40/43

A = sin^-1(40/43)

A = 68.47109559 = 68

cos(x) = Adjacent/Hypotenuse

cos(B) = 40/43

B = cos^-1(40/43)

B = 21.52890441 = 22

43^2 - 40^2 = 3449 Pythagoras' Theorem

$\sqrt{249}$ = 15.77973384 = 15.8

I hope this helps!!

Option D:

$\frac{25 a^{9} b^{10} }{6 }$ is equivalent to the given expression.

Solution:

Given expression:

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}$

To find which expression is equivalent to the given expression.

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}$

Using exponent rule: $(ab)^m=a^mb^m$

$$=\frac{5^3 a^3 b^{3}}{30 a^{-6} b^{-7}}$

Using exponent rule: $\frac{1}{a^{m}}=a^{-m}, \quad \frac{1}{a^{-m}}=a^{m}$

$$=\frac{125 a^3 b^{3}a^{6} b^{7}}{30 }$

$$=\frac{125 a^3 a^{6} b^{3} b^{7}}{30 }$

Using exponent rule: $a^{m} \cdot a^{n}=a^{m+n}$

$$=\frac{125 a^{3+6} b^{3+7} }{30 }$

$$=\frac{125 a^{9} b^{10} }{30 }$

Divide both numerator and denominator by the common factor 5.

$$=\frac{25 a^{9} b^{10} }{6 }$

$$\frac{(5 a b)^{3}}{30 a^{-6} b^{-7}}=\frac{25 a^{9} b^{10} }{6 }$

Therefore, $\frac{25 a^{9} b^{10} }{6 }$ is equivalent to the given expression.

Hence Option D is the correct answer.

Amanda [17]

Answer:

63/70 is simplified to 9/10 in fraction form and 0.9 in decimal form.

14/30 is simplified to 7/15 in fraction form and 0.46 in decimal form.

24/36 is simplified to 2/3 in fraction form and 0.6 in decimal form.

10/50 is simplified to 1/5 in fraction form and 0.2 in decimal form.

40/56 is simplified to 5/7 in fraction form and 0.714285 in decimal form.

18/24 is simplified to 3/4 in fraction form and 0.75 in decimal form.

You can simplify these and future questions by cancelling out the numerator's and denominator's LCF (Least Common Factor). I hope this helps!
