Five less than half the distance from Delaney’s home to the mall is more than 6 miles.
vovikov84 [41]

let x = the distance from Delany's house to the mall

 so half the distance would be 1/2x

then it is 5 miles less than that so you would subtract 5 to give you 1/2x-5

and that is more than 6 miles so you get 1/2x-5>6

HIJK is a rectangle. HJ=x and IK=2x-7 Find the length of each diagonal​
laila [671]

Val needs to find the area enclosed by the figure. The figure is made by attaching semicircles to each side of a 58​-by-58 squar
Savatey [412]

Answer:

We need to find the area of the semicircles + the area of the square.

The area of a square is equal to the square of the lenght of one side.

As = L^2 = 58m^2 = 3,364 m^2

Now, each of the semicircles has a diameter of 58m, and we have that the area of a circle is equal to:

Ac = pi*(d/2)^2 = 3.14*(58m/2)^2 = 3.14(27m)^2 = 2,289.06m^2

And the area of a semicircle is half of that, so the area of each semicircle is:

a =  (2,289.06m^2)/2 = 1,144.53m^2

And we have 4 of those, so the total area of the semicircles is:

4*a = 4* 1,144.53m^2 = 4578.12m^2

Now, we need to add the area of the square 3,364 m^2 + 4578.12m^2 = 7942.12m^2

This is nothing like the provided anwer of Val, so the numbers of val may be wrong.
