Mario is constructing a wall around a rectangular area which will cover a maximum of 60 square feet. The length of the wall will

Feliz [49]

Answer:

$W \le 6$

Step-by-step explanation:

Given

$Area = 60ft^2\ (max)$

$Length = 10ft$

Required

Represent the width as an inequality

First, we represent the area as an inequality.

$Area = 60ft^2\ (max)$

max as used above means less than or equal to.

So, we have:

$Area \le 60$

The area of a rectangle is:

$Area = L * W$

So, we have:

$L * W \le 60$

Substitute 10 for L

$10 * W \le 60$

Divide both sides by 10

$\frac{10 * W}{10} \le \frac{60}{10}$

$W \le \frac{60}{10}$

$W \le 6$

Strike441 [17]

Answer:

(x − 5) (x + 4)

Step-by-step explanation:

x² − x − 20

Factor using AC method:

1 × -20 = -20

Factors of -20 that add up to -1: -5 and 4

Divide by 1 and reduce: -5/1 and 4/1

275 miles in 5 hours

55 miles in one hour

Check

to check if im right

275×2 would be how many miles she drove in 10 hours rght ? 275×2=550

550 miles in 10 hours

we know one hour is 55 miles & 5 hours is 275 & 10 hours is 550

10 hours plus 3 hours = 13 hours right ?

55 ×3 = 165

550 +165=715

715 miles in 13 hours

Step-by-step explanation:

715÷13 to get how many miles she drove in one hour .

=55 miles in 1 hour .

then multiply 55 ×5 to get how many miles she drove in 5 hours

55×5=275

275 miles in 5 hours

Sonji and her friend rachel are competing in a race. When sonji is 0.4 miles from the finish line she notices that her friend ra

goldfiish [28.3K]

Answer:

Sonji is 0.5 miles far from the finish line

Step-by-step explanation:

Data provided in the question:

Distance between the Sonji and the finish line = 0.4 miles

Distance run by Sonji back = one tenth of a mile

i.e = $\frac{1}{10}$ miles = 0.1 miles

Hence,

The total distance of Sonji from the finish line will be

= Distance between the Sonji and the finish line + Distance run by Sonji back

= 0.4 miles + 0.1 miles

= 0.5 miles

Hence,

Sonji is 0.5 miles far from the finish line
