Easy 30 Points!!!!!!!A microscope shows you an image of an object that is 20 times the object's actual size. So, the
scale factor of the enlargement is 20. An insect has a body length of 2 millimeters. What is the
body length of the insect under the microscope?
40 centimeters
40 millimeters
4 millimeters
400 millimeters
Answer:
1
Step-by-step explanation:
Answer:
Keywords:
Microscope, scale factor, enlargement, actual length, length to scale
For this case we have a microscope that shows an enlargement scale of objects, 140 times the actual size. Given the actual length of an insect, we want to know the scale length shown by the microscope. So, we have the following equation:
If the insect has a , then:
Thus, the microscope will show the insect with a size of 840mm
Answer:
The body length of the insect under the microscope is 840mm

what is the slope of (-8, -3) (-24, 1)
Answer:
(-16 , -4)
Step-by-step explanation:
you use rise over run
the rise is your y
the run is the x
[tex]\frac{y2-y1}{x2-x1}[/tex]⇒[tex]\frac{-3-1}{-24-(-8)}[/tex] =
[tex]\frac{-4}{-16}[/tex] or (-16, -4)

I might be wrong but that's what I got.
Answer:
6 1/3 or 6.333333. . .
Step-by-step explanation:
Original Equation:
2(y - 4) + 4y = 11 + 3y
Use distributive property.
2 x y = 2y
2 x (-4) = -8
Plug these values back into the equation:
2y - 8 + 4y = 11 + 3y
Add 8 to both sides
2y + 4y = 19 + 3y
Add 2y and 4y together
6y = 19 + 3y
Subtract 3y from both sides
3y = 19
Divide both sides by 3
6.3333333333333333333. . . . .
6 1/3

pls help? i dont understand this.
Answer:
The answer is x=86
Step-by-step explanation:
1st set up an equation
104+(x-10)=1802nd combine like term i.e, 104 and -10
94+×=1803rd isolate x; you would do this by subtracting 94 on both sides of the equation
x=86You're final answer is x=86
You have 3 apples, 4 pears, 7 oranges, and 14 bananas. Your friend gives you 5 times that amount. Your other friend gives you 75 times more. (lots of fruit am i right) Your friend then takes half of it away. How much fruit do you have left?
Answer:
6384
Step-by-step explanation:
Since the question is only talking about fruit, I'm going to ignore which type and add the fruits together.
3+4+7+14=7+7+14=14*2=28
I have 28 fruits, and my friend give me 5 times that, so my friend gives me 5*28, or 140 fruits. So in all, I have 140 plus my original 28, or 168 all together
Then, my other friend gives me 75 times more. Wow. I don't think I've seen this many fruits all in one place, but this is the world of math, so who cares?
75*168=(70*168)+(5*168)=7000+4200+560+500+300+40=11760+840=
12600 fruits that your friend gives you. In addition to the 168 that you had before. Pardon my french, but why the ...
12600+168=12768 fruits at the height of your fruity domination.
Then, your friend takes half
12768/2=6384 fruits.

HURRY 10 min left!!! Consider the triangle. Which statement is true about the lengths of the sides? A. Each side has a different length. B. Two sides have the same length, which is less than the length of the third side. C. The three sides have the same length. D. The sum of the lengths of two sides is equal to the length of the third side.
Answer:
B. Two sides have the same length, which is less than the length of the third side.
Step-by-step explanation:
Find the diagram attached.
From the diagram, we can see that the triangle is right angled with two of its angles equal. This can also be an isosceles triangle. An isosceles triangle is a triangle that has two of its sides and angles equal.
Since two of the angles are the same, this means that two of its sides are also the same.
Let the two sides that are equal be 1. pythagoras theorem, the third sides will be expressed as;
d² = 1²+1² (true for a right angled triangle)
d² = 2
d = √2
d = 1.414
You can see that the length of the third side is greater than the other two sides.
Hence the correct option is B. Two sides have the same length, which is less than the length of the third side

Reflect the point (-7, -9) across the x-axis: Then
Reflect the point (-7, -9) across the y-axis:
Step-by-step explanation:
Reflecting across the x axis will result in a sign change for. the y component, therefore (-7,-9) becomes (-7,9)
Reflecting across the y axis will result in a sign change for the x component, therefore (-7,-9) becomes (7,-9)

Which word describes the slope of the line?
Answer:
rate of change
Step-by-step explanation:
Answer:
"rise over run" or "rate of change"
Step-by-step explanation:
"Slope" itself is "rise over run", or how quickly the line moves up or down relative to the x-axis as the value of x changes.
A gradient is really just another name for slope, not a description OF a slope.
Explain the difference between parallel and perpendicular lines in terms of their slopes. What form of equation of a line is easiest to determine slope?
Answer:
Parallel lines have the same slope, while perpendicular lines have completely opposite slopes. So a line has a slope of 2, a parallel line would have a slope of 2, and a perpendicular line would have a slope of -1/2. The easiest form to identify the slope is standard form because it shows the slope within the equation with out having to solve the equation or convert it into another form.
