Answer:

34) A

35) C

36) D

Step-by-step explanation:

34) The perimeter of a triangle is equal to the sum of the lengths of its sides

Sides: (6.2p + 4.5q) + (3.4p - 0.7r) + (2.9r - 4.1q)

Combine like terms (same variables)

(6.2p + 3.4p) + (4.5q - 4.1q) + (2.9r - 0.7r)

9.6p + 0.4q + 2.2r

A

35)

Time possibilities

1 hour - $3 - $5 = $-2     No

2 hours - $6 - $5 = $1    Yes

3 hours - $9 - $5 = $4    Yes

4 hours - $12 - $5 = $7    Yes

5 hours - $15 - $5 = $10   Yes

6 hours - $18 - $5 = $13   Yes

7 hours - $21 - $5 = $16   Yes

8 hours - $24 - $5 = $19   No

9 hours - $27 - $5 = $22  No

The possible hours that Ms. Barnes can park are 2 - 7 hours

The only inequality graph that represents all of these values is C

36)

<h3>(-\frac{4}{7}) / (-\frac{3}{4}) * (-2\frac{1}{3})</h3>

Convert to improper fractions

<h3>(-\frac{4}{7}) / (-\frac{3}{4}) * (\frac{-7}{3})</h3>

Divide by finding the reciprocal

<h3>(-\frac{4}{7}) * (-\frac{4}{3}) * (\frac{-7}{3})</h3><h3 /><h3>\frac{16}{21} * -\frac{7}{3}</h3><h3 /><h3>\frac{-16}{9}</h3>

Convert back to a mixed number

-1\frac{7}{9}

D

Hope this helps :)

Rounded to the nearest hundredth, what is the positive solution to the quadratic equation 0 = 2x2 + 3x – 8? Quadratic formula: x
Lynna [10]

ANSWER

1.39

EXPLANATION

The given quadratic equation is

0 = 2 {x}^{2}  + 3x - 8

This is the same as,

2 {x}^{2}  + 3x - 8 = 0

Comparing to

a {x}^{2}  + bx  + c = 0

We have

a=2, b=3,c=-8

Using the quadratic formula, the solution is given by:

x =  \frac{ - b \pm \:  \sqrt{ {b}^{2}  - 4ac} }{2a}

We substitute the values to get,

x =  \frac{ - 3\pm \:  \sqrt{ {3}^{2}  - 4(2)( - 8)} }{2(2)}

x =  \frac{ - 3\pm \:  \sqrt{ 73} }{4}

The positive root is

x =  \frac{ - 3 + \:  \sqrt{ 73} }{4} = 1.39

to the nearest hundredth.

What is mean, median, mode,and range.
Alex17521 [72]
Mean is the same as the average
median is the middle number
mode is the number that is used most often
range is the highest number minus the lowest number

example : 
2,3,3,5,7

u find the mean by adding up all the numbers, then dividing by how many numbers there are. (2 + 3 + 3 + 5 + 7) / 5 = 20/5 = 4 (the mean)

the median would be the middle number, and that would be 3

the mode would be the number that appears the most..that would be 3 because it appears twice.

the range is the highest - lowest : 7 - 2 = 5 (the range)...bur dont get this confused by the interquartile range..it is not the same as the range.
