Answer:

1) 36, 2) 14, 3) 19, 4) 18, 5) 3, 6) 117

Step-by-step explanation:

1)  6(7) - 3(2)   2)  (7)(4)/2   3)  (7) + |2(7) - (2)|   4)  6(5) - 4(3)   5)  [(4) + (5)]/3  

    42 - 6             28/2            7 + |14 - 2|               30 - 12            9/3

    36                   14                7 + 12                      18                    3

                                               19

6)  (4) + [(5)^3 + (3)] - 15

     4 + (125 + 3) - 15

     4 + 128 - 15

     132 - 15

     117

one side of a triangle is one-third the longest side. the third side is 11 ft less than the longest side. the perimeter is 73. f
Len [333]

side 1 = x

side 2 = x-11

side 3 = 1/3x


x + x-11 + 1/3x = 73

2x-11 + 1/3x = 73

2x = 6/3x

6/3x+1/3x = 7/3x


7/3x-11 = 73

7/3x = 84

7x =84*3

7x = 252

x = 252/7

x = 36

longest side = 36

2nd side = 1/3(36) = 12

3rd side = 36-11 = 25

Do you agree with Mark’s reasoning? Is he correct that 2 is a rational number? Explain your answer.
VikaD [51]

Well, I don't know Mark's reasoning, but the square root of 2 is not a rational number. A rational number is a number that can be represented by a fraction - its decimal form must either be finite (have an end) or repeat (for example, 1/3 or .3333333...). The square root of 2 is infinite and cannot be written as a fraction, so it's not rational.

The graph shows the distance, y, that a car traveled in x hours:
vesna_86 [32]
Here, You need to calculate the slope of the graph by taking any two random points, as follows:
(x₁,y₁) = (0,0) & (x₂,y₂) = (1,55)

Now, we know, 
y₂-y₁ = m(x₂-x₁)
55-0 = m(1-0)
m = 55/1
m = 55

Here m represents the slope of graph which is nothing but rate of change of distance.

In short, option A will be your answer.

Hope this helps!

Natalie picked 135 berries in 15 minutes. If she continues picking at that rate, how long will it take her to pick 486 berries?
nikklg [1K]
We can use proportion to solve it
135 berries -------------15min
486 berrier --------------x
Our x is equal to =x= \frac{486*15}{135} =54min
Its our result
