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

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
x>2

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%

Jeff mowed a lawn for $20.00 and received a $5,25 tip. He then washed a car for $12.50. How much money
did Jeff make for completing these two jobs?
Answer:
See below.
Step-by-step explanation:
Mowing the lawn: $20
Tip: $5.25
Add them together.
[tex]20+5.25=25.25[/tex]
Washing the car: $12.50
Add that to the amount.
[tex]25.25+12.50=37.75[/tex]
Answer: [tex]37.75[/tex]
:)
Answer "and" Explanation:
Depends on whether this is a simple math problem or a riddle. I’m assuming the latter so…
Jeff received $20.00 for providing a lawn mowing service. Jeff received an additional $5.25 tip. Ignoring costs and taxes, Jeff’s gross receipts were $25.25.
Jeff then decided to wash a car. The ways it’s worded leads me to believe he spent $12.50 on the car wash.
So, $25.25 - $12.50 = $12.75
Alternatively, if Jeff was paid to wash the car then:
$20.00 + $5.25 + 12.50 = $37.75
So the Answer will be: $37.75
