Answer:

PAGE 1

A. Since PEMDAS 2*3 first

2*3 = 6

then 8/2

8/2 = 4

leaving

11 + 7 - 6 + 4

next 11 + 7

11 + 7 = 18

18 - 6 + 4

18 - 6 = 12

12 + 4 = 16

your answer is 16

B. No because John did not complete his problem correctly. The right answer is 16.

PAGE 2

A. Because of PEMDAS 4 * 12 first

4 * 12 = 48

then 48/3 = 16

your equation comes to

48 + 16 -15

then do

48 + 16 = 64

64 - 15 = 49

the answer is 49

B. If you don't do PEMDAS it can cost you the right answer.

See what answer you get when you don't do PEMDAS and just complete the equation left to right

48 + 4 = 52

52 * 12 = 624

624/3 = 208

208 - 15 = 193

the wrong non-PEMDAS used answer would then be 193

hope this helps:)

What is Xavier’s available lot coverage?

slavikrds [6]

Answer:

Step-by-step explanation:

<h3>At first:</h3>

Given,

Back of lot of the trapezoid = 175

Front of lot of the trapezoid = 185

Length of lot of the trapezoid = 100

Therefore, 

Area of the trapezoid

$= \frac{a + b}{2} c$

[On putting the values]

$= \frac{175 + 185}{2} \times 100$

[On Simplification]

= 360 × 50

[On multiplying]

= 18000

Hence,

We got the Total Area as 18000.

As per given equation,

$\frac{40}{100} = \frac{x}{total \: area}$
To find the value of x

Solution ,

$= > \frac{40}{100} = \frac{x}{total \: area}$

[On putting Total Area = 18000]

$= > \frac{40}{100} = \frac{x}{18000}$

[On cross multiplication]

=> 40 × 18000 = 100 × x

[On Simplification ]

=> 720000 = 100x

[On dividing both sides with 100]

$= > \frac{720000}{100} = \frac{100x}{100}$

[On Simplification ]

=> x = 7200

Hence,

Xavier's avaliable lot coverage (x) = 7200 (Ans)
