1. JP Construction is building a rectangular children's wading pool for the local community center. The pool will be 4.5 meters

Bond [772]

Answer:

$x\leq 1.78$

Step-by-step explanation:

We are given that

Width of pool, b=4.5 m

We have to find the inequality which represents the possible lengths of the wading pool.

Let x be the length of wading pool

We know that

Area of rectangle= $length\times breadth$

According to question

Using the formula

$4.5x\leq 8$

Divide by 4.5 on both sides we get

$x\leq\frac{8}{4.5}$

$x\leq 1.78$

Pentagon ABCDE is a regular polygon. The length of side BC is represented by 3x - 4. The length of side DE is represented by the

dimulka [17.4K]

Answer:

Length of side AB = 5

Step-by-step explanation:

A regular polygon is one in which all angles are equal and all the sides have the same length.

Now, it means that;

AB = BC = CD = DE = AE

We are told that BC is represented by 3x - 4 while DE is represented by the expression 4x - 9.

Thus, from equal length of sides of a regular polygon, we have;

3x - 4 = 4x - 9

4x - 3x = 9 - 4

x = 5

Thus, length of BC = 3(5) - 4 = 15 - 4 = 11

Therefore, Length of AB = 5

Greg’s house is 0.8 miles from the library. So far, Greg has walked 5/6 of the distance. How many miles has he walked in fractio

Anastaziya [24]

Greg has walked $\frac{2}{3}$ miles

<em><u>Solution:</u></em>

Given that, Greg’s house is 0.8 miles from the library

Distance between house and library = 0.8 miles

Greg has walked $\frac{5}{6}$ of the distance

Therefore,

Distance walked = $\frac{5}{6}$ of the distance between house and library

Here "of" means multiplication

Thus we get,

$\text{Distance walked } = \frac{5}{6} \text{ of } 0.8$

$\rightarrow \frac{5}{6} \times 0.8 = \frac{5}{6} \times \frac{8}{10}\\\\\text{Simplify the above fraction by reducing to lowest terms }\\\\\rightarrow \frac{5}{6} \times \frac{8}{10}=\frac{2}{3}$

Thus Greg has walked $\frac{2}{3}$ miles
