What is 26 percent of 2.21
Rashid [163]
You have to do mutiplication. how do you know that you have to do mutiplcation because the (of) it means times. so  26 * 2.21 = 0.5746
         2.21/x=100/26
<span>(2.21/x)*x=(100/26)*x      </span>
<span>2.21=3.8461538461538*x      
</span>(3.8461538461538) to get x
<span>2.21/3.8461538461538=x </span>
<span>0.5746=x </span>
<span>x=0.5746</span>

Dafna11 [192]

Answer:

2.2 results in a true equation, 2.2 is a solution to the equation.

Step-by-step explanation:

Step 1. Substitute the number for the variable in the equation.

Step 2. Simplify the expressions on both sides of the equation.

Step 3. Determine whether the resulting equation is true.

If so, the number is a solution.

If not, the number is not a solution.

Find the sum of the infinite geometric sequence:<br>8, 4, 2, 1, .......​
tatyana61 [14]

Answer:

<h3>Therefore the sum if the series is 15.98!</h3>

The common ratio is 1/2 or 0.5 . If you multiply the current term by the the common ratio the the output will be the next term.

8⋅1/2=4

4⋅1/2=2

2⋅1/2=1 etc ...

because the absolute value of r is less than 1 we can use the following formula.

a/1−r where a is the first term and r is the common ratio

In our problem

a=8 and r=0.5

Substitute

8/1−0.5=8/0.5=16

The sum of this infinite geometric series is 16.

Also, another formula you can use that is guaranteed to work every time, no matter what, is:

Sn=a(r^n−1/r−1)

All the variables work the same way as above, and "n" is the number of terms in the series. So, say you wanted to find the sum of the first 10 terms and were to substitute everything in:

S10=8(0.5^10−1/0.5−1)

S10=15.984375

Therefore the sum if the series is 15.98!

In a local car lot, 1/6
Black_prince [1.1K]

Answer: \dfrac{5}{324}

Step-by-step explanation:

Given

Probability that car has a standard transmission is \frac{1}{6}

So, the probability that the car does not have transmission is

1-\dfrac{1}{6}=\dfrac{5}{6}

Probability of that 3 out of 4 randomly selected cars have standard transmissions is given by selecting 3 cars with standard deviation and then multiply by their respective probabilities

\Rightarrow P=^4C_3\cdot \left(\dfrac{1}{6}\right)^3\cdot \left(\dfrac{5}{6}\right)\\\\\Rightarrow P=4\times\dfrac{5}{6^4}\\\\\Rightarrow P=\dfrac{20}{1296}\\\\\Rightarrow P=\dfrac{5}{324}
