Answers

Answer 1

Answer: $8^(3)$ * $8^(-5)$
8^3 is 8*8*8=512
so its 512*8^-5
According to my calculator 8^-5 is 0.00003051757
so its 512*0.00003051757=0.01562499584

Answer 2

Answer: $8^38^(-5)=8^(3-5)=8^(-2)= (1)/(8^2) = (1)/(64) =0,015625$

Step-by-step explanation:

The sum of the interior angle measures is 180°. Find the value of X.

Answers

Answer:

Step-by-step explanation:

By the Triangle Angle-Sum Theorem, the angles of a triangle add up to equal 180, regardless of the size of the triangle. We are given the angle measures, so adding them together and setting them equal to 180 is

60 + 3x + x + 20 = 180 and, combining like terms,

4x + 80 = 180. Subtracting 80 from both sides,

4x = 100 so

x = 25

Which is heavier 75kg or 110lbs

Answers

1 kg is equal to a little over twice the lbs. So if you have 75 kg it'll be over 150 lbs. Therefore 75 kg weighs more.

75kg because 75kg = 165.347lbs

What does g equal if the equation is 76=g2nd power

Answers

$\sf76=g^2$

Find the square root of both sides:

$\sf~g=√(76)$

$\sf~g\approx8.72$

If 76 is 'g to the second power', then 'g' is the square root of 76.

Every positive number has two square roots.

The square roots of 76 are irrational numbers ... they can't be written exactly
with just digits. When they're rounded to a reasonable number of decimal
places, they are ...

g = + 8.7178
and
g = - 8.7178 .

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Chuanxi planned a rectangular sidewalk with a length of 21 ft. He made a scale drawing using a scale factor of 1 in. = 7 ft. He decided to change the length of the actual sidewalk to 27 ft.

The value of 1 inch will be calculated as,

Original Ratio of 1 in = 7 ft so 3 in = 21 ft

Now, New ratio 1 in = x ft so 3 in = 27ft

1/x = 3/27
