The angles with measurements equal to 3x+3 and 2x+22 should add up to 180°. This is because the angle which measures 2x+22 and the angle that is adjacent to the angle measuring 3x+3 are supposed to be congruent. If we mathematically translate the concept above, this can be expressed as,
3x + 3 + 2x + 22 = 180

Combining like terms,
(3x + 2x) + (3 + 22) = 180
Simplifying,
5x + 25 = 180

Transpose the constants to only one side of the equation,
5x = 155
Divide the equation by 5.
x = 31

<em>ANSWER: x = 31</em>

Explain the steps for converting a terminating decimal into a rational number (fraction). Use the decimal 0.25 to provide an exa

forsale [732]

Terminating decimal
rmember that all numbers can be put over 1 and that is a fraction
ex
1/1=x
3/1=3
π/1=π

so therefor
0.25=0.25/1
if yo want to make the top number equal a whole number
multiply top and bottom by 100 to move 0.25 two decimal places to the right to make it ahwole number

0.25/1 times 100/100=25/100=1/4
answer is 1/4

steps:
1. find how many decimal placees the number goes to (ex. 0.25=2 places 0.2=1 place, 0.2345=4 places)
2. put the decimal over 1 (so if the decimal is x then do x/1)
3. find a fraction that is 10/10 such that the number of zeros one the top should be equal to the zeroes on the bottom, the number of zeros on the top should be equal to the number of decimal places from step 1
4. multiply the fraction (x/1) from step 2 by the fraction from step 3
5. simplify the resulting fraction

The question is to find x

slava [35]

Answer:

x =5

Step-by-step explanation:

Tangents from same external point have equal length.

KJ = LJ

4x - 1 = 2x + 9

Add 1 to both sides

4x = 2x + 9 + 1

4x = 2x + 10

Subtract '2x' from both side

4x - 2x = 10

2x= 10

Divide both sides by 2

x = 10/2

x = 5

Write a equation representing the area Bruce covered, y, in terms of the number of tiles he used,x.

diamong [38]

Answer: y = 4x

Step by step explanation:

If each tile is ¼ of a square foot then y (in terms of square feet) will be equal to x / 4 meaning that the equation would be y = 4x

Tanzania [10]

Answer:

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of $\pi$ , and a confidence level of $1-\alpha$ , we have the following confidence interval of proportions.

$\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}$

In which

z is the zscore that has a pvalue of $1 - \frac{\alpha}{2}$ .

For this problem, we have that:

560 random tests conducted, 26 employees failed the test. This means that $n = 560, \pi = \frac{26}{560} = 0.046$

98% confidence level

So $\alpha = 0.02$ , z is the value of Z that has a pvalue of $1 - \frac{0.02}{2} = 0.99$ , so $Z = 2.33$ .

The lower limit of this interval is:

$\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 - 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.025$

The upper limit of this interval is:

$\pi + z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.046 + 2.33\sqrt{\frac{0.046*0.954}{560}} = 0.067$

The 98% confidence interval for the proportion of applicants that fail the test is (0.025, 0.067).
