Calculate a rough estimate of the total lineal footage of lumber needed for a rectangular house 35’ x 40’?
Maru [420]

Answer:

B. 1,500’

Step-by-step explanation:

Given;

dimension of the rectangular house, = 35’ x 40’

The actual total linear footage of lumber needed = 35’ x 40’ = 1,400'

The rough estimate should be greater than the actual estimate in 100s;

rough estimate = 1,400' + 100' = 1,500'

Therefore, the rough estimate of the total linear footage of lumber needed is 1,500'.

Which of the following is the graph of the solution set of t – 4 ≥ 4t + 8 or 3t >14 – 4t?
Stells [14]

Answer:

Option (C)

Step-by-step explanation:

There are two inequalities,

t - 4 ≥ 4t + 8 ------(1)

3t > 14 - 4t ------(2)

By simplifying inequality (1),

t - 4 ≥ 4t + 8

t ≥ 4t + 8 + 4

t ≥ 4t + 12

t - 4t ≥ 12

-3t ≥ 12

t ≤ \frac{12}{(-3)}

t ≤ -4

By solving inequality (2),

3t > 14 - 4t

3t + 4t > 14

7t > 14

t > \frac{14}{7}

t > 2

From the given graphs, Option (C) will be the answer.

A robot’s height is 1 meter 20 centimeters. How tall is the robot in millimeters? Please show me how you work it out.
solmaris [256]

Answer:

1200 millimeters

Step-by-step explanation:

Given

Height=1 meter 20 centimeter

In order to convert the height into millimeter we have to convert to millimeter

We will have to convert the meters into centimeters and then centimeters into millimeter.

So,

We know that

1 meter=100 cm

So total height in centimeters will be:

1 meter 20 centimeter=100+20  

= 120 cm

In order to convert centimeters into millimeters, we will use

1 cm=10 millimeter  

To convert into smaller unit, multiplication is used,

So,

120 cm=120*10

=1200 mm

So the height in millimeter is 1200 ..
