27. How wide is the oil spill?
CLEAR ALL
The two triangles given in the diagram are said to be similar, so that their sides can be compared. Therefore, the width of the oil spill is 50 km.
A triangle is a figure with three sides. Two or more triangles are said to be similar if and only if their sides have relating figures. Thus, to determine the width of the oil spill, the two given triangles are to be compared. This would result to:
[tex]\frac{20}{40}[/tex] = [tex]\frac{25}{x}[/tex]
x = [tex]\frac{40*25}{20}[/tex]
= [tex]\frac{1000}{20}[/tex]
= 50
x = 50 km
Therefore the width of the oil spill is 50 km.

The rates of change of two data sets can be compared by finding:
the initial values.
ООО
the slope of each trend line.
how close the points are to the line.
the y-intercepts.
Answer:
the slope of each trend line
Step-by-step explanation:
The rate of change of the variables (dependent and independent) in the linear model is given by the slope or gradient of the regression model usually represented as :
y = bx + c ; where b is the slope and gives the change in y per change in the value of x.
Hence, when intending to find the rate of change of different Datasets, the slope of the trend line corresponding to each dataset is compared in other to determine the identify the differences in the rate of change of each dataset.

A piece of wire is 7/8m long broke into two piece one piece is 1/4 m long how long is the other one ?
Answer: 5/8m
Step-by-step explanation:
From the question, we are informed that a piece of wire is 7/8m long and broken into two piece. We are further told that one piece is 1/4 m long.
The length of the other piece of wire would be calculated as:
= 7/8 - 1/4
= 7/8 - 2/8
= 5/8m

Determine whether the graph represents a proportional or non-proportional relationship. Then select the correct equation in the form y=mx or y=mx+b to represent the relationship between the independent and dependent quantities.
This graph is an example of a blank area relationship. The equation that represents the relationship between the independent and dependent quantities is blank area.

y=60x
y=x+30
Help me fill in the blanks that say blanks
Answer:
Non-proportional
y = [tex]\frac{2}{15}x+20[/tex]
Step-by-step explanation:
If a line doesn't pass through the origin relationship represented by the line is non proportional.
In other words, any line having y-intercept is non-proportional.
From the graph attached,
Line has a y-intercept = 20
Therefore, relationship is non-proportional.
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex],
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Since, the given line is passing through (0, 20) and (60, 28),
Slope of the line 'm' = [tex]\frac{28-20}{60-0}[/tex]
m = [tex]\frac{8}{60}[/tex]
= [tex]\frac{2}{15}[/tex]
y-intercept 'b' = 20
Slope-intercept form of the equation is,
y = mx + b
So the equation will be,
y = [tex]\frac{2}{15}x+20[/tex]

What is the value of x when solving the equation 4 x + (negative 4) = negative 2 x + 8 using the algebra tiles?
x = negative 4
x = negative 2
x = 2
x = 4
Answer:
x = 2
Step-by-step explanation:
4 x + (negative 4) = negative 2 x + 8
4x + (-4) = - 2x + 8
4x - 4 = - 2x + 8
4x + 2x = 8 + 4

Aluminum and tin are both metals. The standard atomic weight for aluminum is 26.98. The standard atomic weight for tin is 118.71.Estimate the difference between the standard atomic weights of these two metals
Answer:
92
Step-by-step explanation:
To estimate the difference between the standard atomic weights of these two metals we round up the given weights to the nearest whole number
The standard atomic weight for aluminum is 26.98.
To the nearest the whole number = 27
The standard atomic weight for tin is 118.71
To the nearest whole number = 119
Hence,
The estimated difference = 119 - 27
= 92

Which statements are true about function g?
Function g is increasing over the entire domain.
As x approaches negative infinity, approaches positive infinity.
Function g includes an exponential piece and a quadratic piece.
As x approaches positive infinity, approaches positive infinity.
Function g is continuous.
Answer:
B, D, and E.
B: As x approaches negative infinity, g(x) approaches positive infinity.
D: As x approaches positive infinity, g(x) approaches positive infinity.
E: Function g is continuous.
Step-by-step explanation:
To answer this question, we will graph it. Please refer to the graph below.
Let’s go through each of the answer choices.
A) Function g is increasing over the entire domain.
Looking at the graph, we can see that this is not true.
More specifically, the red curve is decreasing over its entire interval.
So, A is not correct.
B) As x approaches negative infinity, g(x) approaches positive infinity.
This is true. As x approaches negative infinity i.e. as we go towards the left of the graph, we can see that our function g(x) (the red curve) is approaching positive infinity.
C) Function g includes an exponential piece and a quadratic piece.
This is false. The first piece is indeed exponential, but the second piece is a cubic, not a quadratic.
D) As x approaches positive infinity, g(x) approaches positive infinity.
Again, this is true. As x approaches positive infinity i.e. As we go towards the right of the graph, we can see that our function g(x) (the blue curve this time) is approaching positive infinity.
E) The function is continuous.
For a function to be continuous, it must have no breaks, jumps, and/or gaps.
We can see that our function does not possess any of the above.
So, g(x) is continuous.
Therefore, the correct statements are B, D, and E.

Ella bought some key chains and spent a total of $15. Each key chain cost the same whole-dollar amount. She bought between 4 and 9 key chains. How many key chains did Ella buy? Ella bought key chains
Answer:
5
Step-by-step explanation:
Total amount spent = $15
Number of chain purchased is between 4 and 9
Cost per chain is a the same (whole dollar)
Number of Chain purchased = (total cost / cost per chain)
Since the total cost = $15
The only whole number value which can divide $15 without a remainder and give a value between between 4 and 9 is 3.
Therefore, cost per chain = $3
Hence, number of chain purchased = $15 / $3
= 5
