Answer:
31.5 units^2
Step-by-step explanation:
This is a right triangle
The x dimension is from B to C
-4 to 3 is 7 units
The y dimension is from A to B
5 to -4 = 9 units
The area of a triangle is
A = 1/2 bh
A = 1/2 (7)(9)
= 31.5
Answer:
First one:
31.5 units²
Step-by-step explanation:
AB: 5 - (-4) = 9 units
BC: 3 - (-4) = 7 units
ABC is a right angle triangle with 90° at B
Base: BC
Height: AB
Area:
½ × base × height
½ × 7 × 9
31.5 units²

Calculate the following percent using fraction equivalents. 50% of 64
Answer:
Step-by-step explanation:
50% is [tex]\frac{50}{100}[/tex] but we're working with 64 units, not 100. So, we must find a number that represents 50 but in 64 units.
[tex]\frac{50}{100}=\frac{x}{64}[/tex]
If you solve for x, you get:
[tex]x=\frac{50*64}{100}\\ x=32[/tex]
[tex]\frac{50}{100}=\frac{32}{64}[/tex]

3)
Remains the same as prey population remains the same
4)
Remains the same as predator population remains the same
Answer:
2) Decreases as the habitat is increasingly polluted
Step-by-step explanation:
number 1 make no sense. 3; at the start, say the population is x. but taking into account the pesticide, it cant no longer ramain the same (pesticide kills some of the x) . 4; similar to the case for answer 3
Use the given information to answer the question.
Answer:
D.
Step-by-step explanation:
Comparing Point P and P' by getting any coordinate.
we will take x coordinate
P has x-coordinate 2 while P' has x-coordinate 8
To find the scale factor, we will divide them
=8/2 gives 4 so the scale factor is 4 this means that rectangle PQRS is dilated 4 times of its perimeter.
So,
Perimeter of P'Q'R'S'= 16 × 6 = 64

What is true about the dilation?
It is a reduction with a scale factor between 0 and 1.
It is a reduction with a scale factor greater than 1.
It is an enlargement with a scale factor between 0 and 1.
It is an enlargement with a scale factor greater than 1.
Answer:
A
Step-by-step explanation: :) am sure
Answer: A. A reduction is a dilation that creates a smaller image, and an enlargement (think stretch) is a dilation that creates a larger image. If the scale factor is between 0 and 1 the image is a reduction. If the scale factor is greater than 1, the image is an enlargement.

The volume of the sphere is 904.32 m. To the nearest meter, what is the radius of the sphere????? Use 3.14 for pi.
Answer:
6
Step-by-step explanation:
The formula for the volume of a sphere is [tex]\frac{4}{3} \pi r^3[/tex]. Plugging in the values that you are given, you get:
[tex]904.32=\frac{4}{3}\pi r^3[/tex]
Dividing both sides by pi or 3.14:
[tex]288=\frac{4}{3}r^3[/tex]
Dividing both sides by 4/3:
[tex]216=r^3[/tex]
Taking the cube root of both sides:
[tex]r=6[/tex]

How do you identify the center and radius of a circle?
Answer:
To find the radius You have to take the circumference of the circle and divide it by 2 times π (pi)
To find the center you draw a chord across the circle (a line across the circle near the edge so it cuts the circumference in two places- if you didn't know) then you find the mid point of the chord, and add a chord or two to determine where they meet in the center

The relationship is additive because
the number of gallons can be found by
adding 5 to the number of minutes.
»
The relationship is multiplicative
because the number of gallons can be
found by multiplying the number of
minutes by 8.
The relationship is multiplicative
because the number of minutes can
be found by multiplying the number of
gallons by 8.
Answer:
(C)The relationship is multiplicative because the number of gallons can be
found by multiplying the number of minutes by 8.
Step-by-step explanation:
Given the table below which shows the relationship between the number of minutes that a hose has been on and the number of gallons of water that have been added to a plastic pool.
[tex]\left|\begin{array}{c|c}$Minutes Hose On&$Gallons of Water in Pool\\-------&-------\\0&0\\5&40\\10&80\\15&120\\20&160\end{array}\right|[/tex]
We can see that if we multiply the first column by 8, we will obtain the second column. Therefore the relationship is multiplicative because the number of gallons can be found by multiplying the number of minutes by 8.
The correct option is C.

Are the graphs of the lines in the pair parallel? Explain,
y = 3x - 17
4x - 6y = -6
A.)Yes, since the slopes are the same and the y-intercepts are the same.
B.)No, since the y-intercepts are different.
C.)No, since the slopes are different.
D.)Yes, since the slopes are the same and the y-intercepts are different.
Answer:
C
0 No, since the slopes are different.
Step-by-step explanation:
First, solve the second equation.
-6y=-16-4x
6y=16+4x
y=16/6+4/6x
y=2/3x+8/3
Next, look at the equation of a line's format.
y=mx+b
This means y=(m=slope)*x+b[when x=0, y=b]
In the first equation, y=3x-17, we can see that m=3, and b=-17
In the second equation, y=2/3x+8/3, m=2/3, and b=8/3
We know that m is the slope, and 3 does not equal 2/3.
Lines are only parallel when their slopes are the same
Therefore, the two lines are not parallel since the slopes are different.
