To write a percent as a fraction in lowest terms, first remember that a percent is a ratio that compares a number to 100. 45% can be written as the ratio 45 to 100 or 45/100. Notice however that 45/100 is not in lowest terms so we need to dive both the numerator and denominator by the greatest common factor of 45 and 100 which is 5.

45 ÷ 5 = 9

100 ÷ 5 = 20

Therefore, 45% can be written as the fraction 9/20.

What is the value of x rounded to nearest tenth

Ivahew [28]

Answer:

6.5 cm

Step-by-step explanation:

Here, the tangent line squared is equal to the secant line times the secant line outside the circle.

That is 20.2² = 14.7 * (14.7 + 2x) --> it is 2x because the secant goes through the whole circle.

Simplify: 408.04 = 216.09 + 29.4x

Subtract: 191.95 = 29.4x

Divide: x = 6.528911565 ≈ 6.5 cm

(20 x 40) x 14 = ?

fredd [130]

To solve this problem, we must use the order of operations outlined by PEMDAS, which tells us that we should simplify or compute parentheses first, then exponents, multiplication, division, addition, and finally subtraction.

Using this method, we have to perform the multiplication inside the parentheses first.

(20 * 40) * 14

800 * 14

Finally, we must perform the final operation to simplify this expression, which is multiplication.

800 * 14 = 11200

Therefore, your final answer is 11200.

Hope this helps!

A boat can travel at an average speed of 10 miles per hour in still water. Traveling with the current, it can travel 6 miles in

oksano4ka [1.4K]

Answer: The speed of the current is 2 miles per hour.

Step-by-step explanation:

We know that the speed of the boat is:

S = 10 mph.

When the boat travels with the current, the speed will be:

S = 10mph + x

where x = speed of the current.

When the boat travels against the current, the speed will be:

S = 10mph - x

Now, for a given amount of time T, when the boat travels with the current, it moves a distance of 6 miles.

Then we have the equation:

(10mph + x)*T = 6mi

And against the current, in the same time the boat moves 4 mi, then:

(10 mph - x)*T = 4mi

Then we have the system of equations:

(10mph + x)*T = 6mi

(10 mph - x)*T = 4mi

Now, we can take the quotient of these two equations and get:

((10mph + x)*T)/((10 mph - x)*T) = (6mi/4mi)

(10mph + x)/(10 mph - x) = 3/2

Now we can solve this for x.

(10mph + x) = (3/2)*(10 mph - x)

10mph + x = (3/2)*10mph - (3/2)*x

x + (3/2)*x = (3/2)*10mph - 10mph

(5/2)*x = (1/2)*10mph = 5mph

x = (2/5)*5mph = 2mph.

The speed of the current is 2 miles per hour.

What is six less than three raised to the third power?

Nataliya [291]

Answer:

Step-by-step explanation:

Three raise to third power can be written as $3^3$ . In this three is the base which is raised to third power.

$3^3 = 3*3*3 = 27$

Next we need to subtract 6 from Three raise to third power(i.e from 27)

which can be written mathematically as

$3^3 - 6 = 3*3*3 - 6 \\=> 27 - 6 = 21$

Hence 6 less than three raised to the third power is 21 as explained above.
