What is the equation, in slope-intercept form, of the line
that is perpendicular to the given line and passes through
the point (2, -1)?
A)y = -1/3 x -1/3
B)y = -1/3 x -5/3
C)y = 3x - 3
D)y = 3x - 7
Answers
Answer:
My guess would be D.
Step-by-step explanation:
We can eliminate A and B right away considering the Slope of the first equation is already -1/3 and we need the slope to be opposite to be perpendicular. So right then It is either C or D. and with C It doesn't seem like the line intersecting the line above would be parallel so my guess is D.

Why do plants provide animals with fruits such as strawberries, apples, and mangoes?
Answers
Answer:
For seed transfer. If an animal gathers fruit and eats it or just carries it away for later consumption, it will move the seed further away from the parent plant. That way, the new plants do not take from the parent plant's resources.

The part of a cylindrical soup can that is covered by the label is 8.5 cm tall and has a diameter of 6.5 cm. What is the area of a label that covers the entire side of the can and that need a 0.8-cm overlap to glue the ends of the label? Round to the nearest tenth.
Answers
Answer:
[tex]180.4~cm^2[/tex]
Step-by-step explanation:
Surface Area
The surface area of a cylinder of height h and radius r is given by:
[tex]A=2\pi rh[/tex]
It only covers the lateral side of the cylinder. If both the top and the bottom sides are to be included, then:
[tex]A=2\pi rh+2\pi r^2[/tex]
The label will cover only the lateral side of the soup can that has a height of h=8.5 cm and a diameter of 6.5 cm. We need to calculate the radius which is half of the diameter r=6.5 cm / 2 = 3.25 cm.
Now we calculate the side area of the can:
[tex]A=2\pi (3.25)(8.5)[/tex]
[tex]A=173.6~cm^2[/tex]
We need to add the 0.8 cm overlap to the total area already calculated. This overlap has 0.8 cm of width and 8.5 cm of height, so this overlap area is:
[tex]A_o= 0.8*8.5=6.8~cm^2[/tex]
The total area of the label is:
[tex]A=173.6~cm^2+6.8~cm^2=180.4~cm^2[/tex]
The area of the label is [tex]\mathbf{180.4~cm^2}[/tex]

200% of the full price is $____
Answers
Given:
An annual pass to a park costs $120.
To find:
The 200% of the full price using percent model.
Solution:
In the percent model,
100% = 1 box
It means 1 box represents park costs $120.
200% = 2 box
[tex]120+120=240[/tex]
It means 2 box represents park costs $240.
Therefore, 200% of the full price is $240.

Find the length of line segment UV.
Answers
Answer:
The length of the line segment UV is 76 units
Step-by-step explanation:
In a triangle, the line segment joining the mid-points of two sides is parallel to the third side and equal to half its length
In Δ ONT
∵ U is the mid-point of ON
∵ V is the mid-point of TN
→ That means UV is joining the mid-points of two sides
∴ UV // OT
∴ UV = [tex]\frac{1}{2}[/tex] OT
∵ UV = 7x - 8
∵ OT = 12x + 8
∴ 7x - 8 = [tex]\frac{1}{2}[/tex] (12x + 8)
→ Multiply the bracket by [tex]\frac{1}{2}[/tex]
∵ [tex]\frac{1}{2}[/tex] (12x + 8) = [tex]\frac{1}{2}[/tex] (12x) + [tex]\frac{1}{2}[/tex] (8) = 6x + 4
∴ 7x - 8 = 6x + 4
→ Add 8 to both sides
∴ 7x - 8 + 8 = 6x + 4 + 8
∴ 7x = 6x + 12
→ Subtract 6x from both sides
∴ 7x - 6x = 6x - 6x + 12
∴ x = 12
→ Substitute the value of x in the expression of UV to find it
∵ UV = 7(12) - 8 = 84 - 8
∴ UV = 76
∴ The length of the line segment UV is 76 units
At the time this question was written, one US Dollar equaled 0.88 Euros. What would 50 Euros equal in US Dollars? Round your answer to the nearest cent.
Answers
Answer:
$56.82 US dollars
Step-by-step explanation:
Set up a proportion where x is how many US dollars there are in 50 Euros:
[tex]\frac{1}{0.88}[/tex] = [tex]\frac{x}{50}[/tex]
Cross multiply and solve for x:
0.88x = 50
x = 56.82
So, 50 Euros is approximately equal to $56.82 US dollars
I believe it is AAS but am not sure whether ASA could be true as well
Answers
Answer: Choice C) AAS
Nice work on getting the correct answer.
=======================================================
Explanation:
We're given that angle A = angle C. This is shown in green in the diagram below.
AB || DC so we can show that angle ABD = angle CDB by the alternate interior angle theorem. This is shown in red.
Finally, we know that BD = BD which is marked in blue.
Note how the blue segment is not between the red and green angle for any of the two triangles. So we use AAS instead of ASA. The order is important.

She wants the entire enclosed area to be 2400 square feet. Lastly,she needs four corner that costs $5 each ?
Let x represent the length of each side of the pen perpendicular to the house and let y represent the length of the side of the pen parallel to the house.Write a function c(x) for the cost of the materials for the llama pen in terms of x. Simplify

can anyone just explain how to do a distant rate time problems because I'm confused about them
Answers
Answer:
The formula for distance problems is: distance = rate × time or d = r × t. Things to watch out for: Make sure that you change the units when necessary. For example, if the rate is given in miles per hour and the time is given in minutes then change the units appropriately.
Step-by-step explanation:
Here is an example.
Two cars started from the same point, at 5 am, traveling in opposite directions at 40 and 50 mph respectively. At what time will they be 450 miles apart?
After t hours the distances D1 and D2, in miles per hour, travelled by the two cars are given by
D1 = 40 t and D2 = 50 t
After t hours the distance D separating the two cars is given by
D = D1 + D2 = 40 t + 50 t = 90 t
Distance D will be equal to 450 miles when
D = 90 t = 450 miles
To find the time t for D to be 450 miles, solve the above equation for t to obtain
t = 5 hours.
5 am + 5 hours = 10 am

A circle has a radius of 13cm . Find the radian measure of the central angle 0 that intercepts an arc of length8cm . Do not round any intermediate computations, and round your answer to the nearest tenth.
Answers
Answer:
The measure of the center angle is 0.6 radians
Step-by-step explanation:
Mathematically, the length of an arc can be calculated using;
L = theta/360 * 2 * pi * r
where theta is the central angle
In this case, theta = ? , pi = 22/7 and r is 13
cm, length of arc is 8 cm
So we have ;
8 = theta/360 * 2 * pi * 13
360 * 7 * 8 = theta * 2 * 22 * 13
20,160 = 572 theta
theta = 20,160/572
theta = 35.24
let us convert this to radian measure
Mathematically, 1 degree = 0.0175 radian
Thus 35.24 degrees will be 35.24 * 0.0175 = 0.62 radians
To the nearest tenth, this is 0.6 radians
