5 0

Answer:

Area = 2m^8 - 6m^4 + 4.5

Step-by-step explanation:

Given

Base = 2m^4 - 3

Height = 2m^4 - 3

Required

The area

This is calculated as:

Area = 0.5 * Base * Height

Area = 0.5 * (2m^4 - 3) * (2m^4 - 3)

Open brackst

Area = 0.5 * (4m^8 - 6m^4 - 6m^4 + 9)

Area = 0.5 * (4m^8 - 12m^4 + 9)

Open bracket

Area = 2m^8 - 6m^4 + 4.5

Malcolm ran the 440-yard and the 220-yard dash at a track meet.There are 3 in one yard. How many total feet did Malcolm run?Esti
Tresset [83]

For this case we have the following conversions:

1 yard = 3 feet

The estimate distance Is:

400yd = 1200feet

200yd=600 feet

Ten, the estimate Is:

1200 + 600 = 1800 feet

The real distance Is:

The total distance in yards is given by:

440 + 220 = 660 yd

Then, let's transform this distance to feet, with the given conversion:

660 * 3 = 1980 feet

The distance traveled is reasonable for a person

Comparing the estimate and the actual answer, the distance malcom Ran Is reasonable.

Answer:

Malcolm ran 1980 feet.

The distance is reasonable.

Write the equation of the line that passes through the points (−7,5) and (-7,-8).
Viefleur [7K]

Answer:

x = -7

Step-by-step explanation:

First we find the slope using

m = ( y2-y1)/(x2-x1)

   = ( -8 - 5)/( -7 - -7)

   = (-8-5)/(-7+7)

   = -13/0

This means the slope is undefined and the line is vertical

Vertical lines are in the form

x= constant and the constant is the x value of the points

x = -7

Kiran and his cousin work during the summer for a landscaping company. Kiran's cousin has been working for the company longer, s
Marta_Voda [28]
Kiran earns $8.50 per hour.

Let x represent Kiran's pay.  He worked 23 hours last week, so his pay would be given by 23x.

Kiran's cousin is paid 30% more.  30% = 30/100 = 0.3.  We add this to the x per hour that Kiran is paid:

x + 0.3x = 1.3x

This is multiplied by 27, since Kiran's cousin works 27 hours:
27(1.3x)

This gives us the following equation:
23x + 27(1.3x) = 493.85
23x + 35.1x = 493.85
58.1x = 493.85

Divide both sides by 58.1:
58.1x/58.1 = 493.85/58.1
x = 8.5

Thus Kiran earns 8.50 per hour.
