Step-by-step explanation:
Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
The length is 3x + 7
The width is 2x + 2
The perimeter is
<h3>2( 3x + 7) + 2( 2x + 2)</h3>
Simplify
6x + 7 + 4x + 4
Group like terms
6x + 4x + 7 + 4
We have the final answer as
<h3>10x + 11</h3>
Hope this helps you
Answer:
w= 7
Step-by-step explanation:
8w + 9w - 1 + 62 = 180
17w + 61 = 180
17w = 119
w = 7
Answer:
0.50
Step-by-step explanation:
X ___ - 5 ___ 3 __ - 2 __ 0 __ 12 __ 3
P(x) __0.17_0.13_0.33 _0.16 _0.11 _0.10
P(x <0) = p(x = - 2) + p(x = - 5)
P(x < 0) = 0.33 + 0.17
P(x < 0) = 0.50
A histogram is used to show the frequency of data, where the length of the bar represents the frequency.
<em>From the histogram, 50 students drank the recommended amount of water.
</em>
Given that
or more
The number of students who drank the recommended amount are students whose frequency is at least 48
From the attached histogram, only 1 bar has a frequency that is at least 48 or more
And the number of students in this bar is: 50
Hence, 50 students drank the recommended amount of water,

Answer:
k= 1 mile per minute
Step-by-step explanation:
There is a proportional relationship between the time (in minutes) Dave spends riding the train, x, and the distance he travels (in miles), y.
The table representing this information is given below:

The equation of proportionality is given as: y=kx
When x=8, y=8
Substituting we have:
8=8k
Divide both sides by 8
k=1
Therefore, the constant of proportionality, k= 1 mile per minute
