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

Since starting a new recycling plan, Hannah's office recycles 2 kilograms of paper each
week. How many weeks will it take Hannah's office to recycle a total of 8 kilograms of
paper?
Answer:
4
Step-by-step explanation:
Known:
Every week Hannah's office recyles 2 kilograms of paper
1 week = 2 kg of paper
To find a rate at which the office recyles paper divide the unit of measurement (kg) by a unit of time (weeks)
So:
2 kg/ 1 week = 2 kg of paper recycled per week
We want to know how many weeks it will take to recycle 8 kg.
Think of it this way.
if you divide kg by kg/week the kg cancel out and you get the unit week.
So divided 8 kg by the rate we discovered (2 kg/week) and you shall get the answer 4 weeks.

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.

If $7,500 investment earns $450 over 3 years what's the interest rate
Answer:
Rate is 2%
Step-by-step explanation:
Step one:
given data
Principal= $7500
Simple interest= $450
time=3 years.
Applying the simple interest formula which is
SI=PRT/100
Step two:
substitute we have
450=7500*R*3/100
cross multiply we have
45000=22500R
divide both sides by 22500
R=45000/22500
R=2%

Answer:
Solve
Let's solve your inequality step-by-step.
10x−14>7x−8
Step 1: Subtract 7x from both sides.
10x−14−7x>7x−8−7x
3x−14>−8
Step 2: Add 14 to both sides.
3x−14+14>−8+14
3x>6
Step 3: Divide both sides by 3
3x/3>6/3
