Which could be the lengths of the sides of a right triangle?
A. 6 cm, 7 cm, 8 cm
B. 7 in., 17 in., 11 in.
C. 9 m, 12 m, 14 m
D. 11 ft, 60 ft, 61 ft

Answers

Answer 1

Answer:

D. 11 ft, 60 ft, 61 ft

Step-by-step explanation:

By using the Pythagorean Theorem, a^2 + b^2 = c^2, we figure out theat 11^2 + 60^2 = 61^2. 11^2 + 60^2 = 61^2, 121 + 3600 = 3721, 3721 = 3721, so option D

Answer 2
D. 11ft, 60 ft, 61ft

What is 34.69$ + 9% (will give brainliest) (explain how you got your answer)

Answers

Answer: $34.78

Step-by-step explanation:

Answer:

$37.81

Step-by-step explanation:

I set up a true proportion equation.

x/$34.69 = 9/100

If you cross multiply, you'll find the value of x, which is 9%.

34.69 x 9 ÷ 100 = 3.12

$3.12 is 9% of 34.69; add them together to get the total.

$34.69 + $3.12 = $37.81

47. Consider the equation x^2/3 =19
Solve the equation, rounding your solutions to two decimal places.

Answers

(Make a shortcut so the problem appears easier.)
Shortcut: x^2/3 = x^1/3 = y^2
(Substitute shortcut in the x^2/3 spot.)

x^2/3 = 19
y^2 = 19
Translate back through the shortcut
x^1/3 = 19
To get x by itself, you would cube it
(x^1/3)^3 = (19)^3
x = 6859

Answer:
x = 6,859

Here’s why:  

We are given the equation of: [tex]m+\frac{4}{3}=2[/tex].I have noted that the (4/3) is a fraction and not a '43'. We would use inverse operations to solve for m.

⸻⸻⸻⸻

[tex]\boxed{\text{Solving for 'm':}}\\\\m +\frac{4}{3} =2\\----------\\\rightarrow m + \frac{4}{3}-\frac{4}{3}=2-\frac{4}{3}\\\\\rightarrow\boxed{m=\frac{2}{3}}\\----------\\\boxed{{2-\frac{4}{3}}}\\\\\rightarrow \frac{2}{1}=\frac{2*3}{1*3}=\boxed{\frac{6}{3}}\\\\\rightarrow\frac{6}{3}-\frac{4}{3}=\boxed{\frac{2}{3}}[/tex]
