1 answer:
MariettaO [177]2 years ago
4 0

Answer:

a. 2/5

b. 1/2

c. 100/9

Step-by-step explanation:

a: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:

.12 × 100 = 12

.3 × 100 = 30

Simplify: 12/30 = 2/5

b: Multiply bottom and top by 1,000 to keep values the same and make the fraction a whole fraction:

.125 × 1,000 = 125

.25 × 1,000 = 250

Simplify: 125/250 = 1/2

c: Multiply bottom and top by 100 to keep values the same and make the fraction a whole fraction:

4 × 100 = 400

.36 × 100 = 36

Simplify: 400/36 = 100/9

Show all work to write the expression in simplified rational exponent form:
tatyana61 [14]

Answer:

x^{\frac{1}{2} } + 48

Step-by-step explanation:

This is hard to explain, but basically you use exponent rules to switch it to an exponent

(\sqrt[4]{x^{2} +4} )^{3}

It's easiest if you calculate 4^{3} first

4³ = 4 x 4 x 4 = 48

Then convert the root to a fraction exponent

\sqrt[4]{x^{2}} = x^{\frac{2}{4}} = x^{\frac{1}{2} }

Combine them using addition, since addition was in the problem

x^{\frac{1}{2} } + 48

I hope this helps!

The measure of one of the small angles of a right triangle is 15 less than twice the measure of the other small angle. Find the
gulaghasi [49]

Answer:

35° and 55°

Step-by-step explanation:

The sum of the angles of a right rectagle is 180°, with a right angle of 90°.

The tell us that A = 2B-15, so:

180° = 90° + A + B

180° = 90° + 2B - 15 + B

180° - 90° + 15 = 2B + B

105° = 3B

B = 105°/3 = 35°

Now, let's find A:

A = 180° - 90° - 35° = 55°
