Answer 1

Answer:

A

Step-by-step explanation:

[tex]\frac{(3x^{2} )^\frac{1}{2} }{3^\frac{1}{2} } =3[/tex]

[tex](3x^2)^\frac{1}{2} = 3^\frac{1}{2} x[/tex]

Remember that [tex]\frac{x^b}{x^c} =[/tex]x^(b-c)

Using that [tex]\frac{3^\frac{1}{2}x }{3^\frac{1}{2} }[/tex]=3^(1/2x-1/2)=3^((x-1)/2)

[tex]3^\frac{x-1}{2} =3^1[/tex]

So we can say: [tex]\frac{x-1}{2} =1[/tex], because the bases are the same

We can multiply both sides of the equation by 2. We get x-1=2, and x=3. Which is A.

In the fraction 15/60, 15 is the numerator and 60 is the denominator.

When you ask "What is 15/60 simplified?", we assume you want to know how to simplify the numerator and denominator to their smallest values, while still keeping the same value of the fraction.

We do this by first finding the greatest common factor of 15 and 60, which is 15.

Then, we divide both 15 and 60 by the greatest common factor to get the following simplified fraction:

the length of the unknown leg is?

Answers

Answer:

a = 10

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is qual to the sum of the squares on the other 2 sides, that is

a² + 24² = 26²

a² + 576 = 676 ( subtract 576 from both sides )

a² = 100 ( take the square root of both sides )

a = [tex]\sqrt{100}[/tex] = 10

Two planes leave an airport at the same​ time, one flying​ east, the other flying west. The eastbound plane travels 130 mph slower. They are 3850 mi apart after 5 hr. Find the speed of each plane.

Answers

Answer:

Speed of the slower plane = 320 mph

Speed of the faster plane = 450 mph

Step-by-step explanation:

Let the speed of the slower plane = x mph

And the speed of the faster plane = y mph

Difference in their speeds = 130 mph

y - x = 130 --------(1)

Formula for the distance traveled = Speed × time

Distance traveled by the faster plane in 5 hours = 5y miles

Distance traveled by the slower plane in 5 hours = 5x miles

Total distance traveled by both the planes in 5 hours = 5(x + y) miles

5(x + y) = 3850

x + y = 770 ---------(2)

By adding equations (1) and (2)

2y = 900

y = 450 mph

From equation (2)

x = 770 - 450

x = 320 mph
