Answer:

n=2

Step-by-step explanation:

25n=2×25

Divide each side by 25

25n/25=2×25/25

n = 2 * 25/25

n =2

Novay_Z [31]

Answer:

<h3>            D){?}    x = 7</h3>

Step-by-step explanation:

x + 3•(+1) = 2•x + 4•(-1)

x + 3  =  2x - 4

  -3         -3

 x  =  2x - 7

-2x      -2x

- x  =  -7

÷(-1)     ÷(-1)

  x = 7

Simplify the square root of 3 times the fifth root of 3.
bogdanovich [222]

Answer:

<h2><em>Three to the three fifths power.</em></h2>

Step-by-step explanation:

The given expression is

\sqrt{3\sqrt[5]{3} }

To simplify this expression, we have to use a specific power property which allow us to transform a root into a power with a fractional exponent, the property states:

\sqrt[n]{x^{m}}=x^{\frac{m}{n}}

Applying the property, we have:

\sqrt{3\sqrt[5]{3}}=\sqrt{3(3)^{\frac{1}{5}}}=(3(3)^{\frac{1}{5}})^{\frac{1}{2}}

Now, we multiply exponents:

(3(3)^{\frac{1}{5}})^{\frac{1}{2}}\\3^{\frac{1}{2}}3^{\frac{1}{10}}

Then, we sum exponents to get the simplest form:

3^{\frac{1}{2}}3^{\frac{1}{10}}=3^{\frac{1}{2}+\frac{1}{10}} =3^{\frac{10+2}{20}}=3^{\frac{12}{20}}  \\\therefore \sqrt{3\sqrt[5]{3}}=3^{\frac{3}{5} }

Therefore, the right answer is <em>three to the three fifths power.</em>

Write the equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3
Inga [223]

Answer:

The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:

\mathbf{y=-\frac{2}{3}x+1}

Step-by-step explanation:

We need to write equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3.

The equation for slope-intercept form is: y=mx+b

where m is slope and b is y-intercept.

We are given slope m = -2/3 and we need to find y-intercept i.e b to write equation of line.

Using point (3,-1) and slope m=-2/3 we can find y-intercept i.e b

y=mx+b\\-1=-\frac{2}{3}(3)+b\\-1=-2+b\\b=-1+2\\b=1

So, y-intercept b = 1

The equation of the line, in slope-intercept form, that passes through (3,-1) and has a slope = -2/3 is:

y=mx+b\\\mathbf{y=-\frac{2}{3}x+1}

A race car driver won a 300 mile race with a speed of 183.2 mph find the drivers time
Ostrovityanka [42]

Answer:

The time taken by the driver is: t = 1.6 seconds

Step-by-step explanation:

Given

Distance covered by a race car = d = 300 mile

Speed of a car = s = 183.2 mph

To determine

The time of the driver = t = ?

Using the formula to determine the time of the driver

distance = speed x time

d = st

t = d/s

substitute d = 300 and s = 183.2

t = 300 / 183.2

t = 1.6 seconds

Therefore, the time taken by the driver is: t = 1.6 seconds
