Masteriza [31]
The perimeter is 41.7

Find the length of each side using the distance formula:
d=\sqrt{(0-0)^2+(-5-9)^2}=\sqrt{0^2+14^2}=\sqrt{196}=14
\\
\\d=\sqrt{(6-0)^2+(-10--5)^2}=\sqrt{6^2+(-5)^2}=\sqrt{36+25}=\sqrt{61}=7.8
\\
\\d=\sqrt{(6-0)^2+(-10-9)^2}=\sqrt{6^2+(-19)^2}=\sqrt{36+361}=\sqrt{397}=
\\19.9

Adding the side lengths, we have
14+7.8+19.9=41.7

HELP!
max2010maxim [7]
For the first question, the total is 240 so that goes in front of the equals sign.  he has already worked 97 hours, so the expression on the right begins with 97 and adds the unknown number of hours, <em>h</em>, to it:
240 = 97 + <em /><em>h</em>

For the second question, there is no graph so I cannot answer it.
3rd question:  no image, can't answer.

4th question:
Use a factor tree:
                          240
                           /  \
                        10*24
                        /\     /\
                      5*2 *8*3
                    /   /    /\    \
                  5 * 2 *4*2 *3
                /     /    /\     \    \
             5   *  2 *2*2 * 2 * 3
Starting with the smallest factor and using exponents we have
2^4*3*5

find the outer perimeter of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate π.​
umka2103 [35]

Answer:

19.42 ft.

Step-by-step explanation:

The diameter of the semicircle is 6, so 3.14 x 6 = 18.84. Since it is a semicircle, we divide that by 2 to get 9.42.

The hypotenuse of the right triangles only matter for the perimeter. 5 + 5 = 10, and 9.42 + 10 = 19.42 ft.

A quarter back completes 29% of his passes. We want to observe this quarterback during one game to see how many pass attempts he
Ann [662]

Answer: P12* = 0.0164 or 1.64%

Therefore, the probability that it takes more than 12 attempts before he completes a pass is 0.0164 or 1.64%

Step-by-step explanation:

Given;

The quarterback's pass accuracy P= 29% = 0.29

The probability of not completing a particular pass P*

= 1 - 0.29 = 0.71

the probability that it takes more than 12 attempts before he completes a pass implies that the quarterback will not complete his first 12 pass attempts.

The probability that he will not complete the first 12 pass

P12* = (P*)^12

P12* = (0.71) ^12

P12* = 0.0164 or 1.64%

Therefore, the probability that it takes more than 12 attempts before he completes a pass is 0.0164 or 1.64%

What is the difference of the two polynomials? (7y2 6xy) â€"" (â€""2xy 3) 7y2 4xy â€"" 3 7y2 8xy â€"" 3 7y2 4xy 3 7y2 8xy 3.
svet-max [94.6K]

The difference between the polynomials is 7y² + 8xy - 3

Polynomials are functions that have a degree of <u>power greater than two.</u>

<u />

According to the question we are to find the difference between the polynomials (7y2 + 6xy) - (-2xy + 3)

f(x, y) = (7y^2 + 6xy) - (-2xy + 3)

f(x, y) = 7y² + 6xy + 2xy - 3

f(x, y) = 7y² + 8xy - 3

Hence the difference between the polynomials is 7y² + 8xy - 3
