Emmanuel wants to tile his rectangular floor. he has two kinds of tiles to choose from, one of which is larger than the other. emmanuel hired your services to help him decide which tile to use.a.what area will be covered by 7"x7" tile? 21"x21" tilwe
b.if the rectangular floor has dimension of 420" by 630"
c.how many big square tiles are needed to cove rthe rectangular floor?
d.if each small tile costs P15.00 and each big tile costs P60.00which which tile should emmanuel use to econimize in tiling his floor? why?

Answers

a).
The 8" by 7" tile covers 49 square inches.
The 21" by 21" tile covers 441 square inches.

b).
The area of the floor is (420" x 630") = 264,600 square inches.

c).
It would take (264,600) / (441) = 600 large tiles to cover the floor.

d).
Emmanuel should use the big tiles to cover his floor.
-- A big tile costs 4 times as much as a small tile, but it has 9 times
as much area as a little tile has, so it is a better buy.
-- Plus, he would have to pay the floorman a lot more to glue down 5,400 tiles
than he will have to pay to glue down only 600 tiles.
-- Since he has hired my services to advise him, I will charge him only 15%
of the difference if he takes my advice, so he will still be money ahead.

Set up a linear equation(s) that will help you to find a solution to the following problem: One angle of a triangle is twice as large as another angle. The measure of the third angle is 20 more than the measure of the smallest angle. Find the measure of each angle of the triangle.

Answers

remember
all angles add to 180

x+y+z=180
one is 2 times as another
x=2y
measure of 3rd angle (z) is 20 more than smalllest
since y has to be doubled to get x, y is smallest
z is 20 more than y
z=20+y

we have
x=2y
z=20+y
sub those
x+y+z=180
2y+y+20+y=180
4y+20=180
minus 20 both sides
4y=160
divide 4
y=40
sub back
x=2y
x=2(40)
x=80
z=20+y
z=20+40
z=60

the angles are
80 degrees, 40 degrees, 60 degrees

Kayla earns 6.5% in commissions on her home sales. She also earns a yearly salary of $12000. She would like to earn a total of $45000 per year. What is the total value of the homes she must sell to achieve her goal? Show the work on how you solve it please, it will be very much appreciated :)

Answers

0.065s+12000=45000

This is the formula you would use. Where 0.065 is 6.5% in decimal form, s is the value of the homes she must sell, 12000 is her yearly salary and 45000 is the total she wants to earn.

0.065s+12000=45000
-12000 -12000
0.065s=33000
-------- --------
0.065 0.065
s=507,692.31 (rounded to the nearest hundredth)

The total value of the homes she must sell to earn a total of $45000 is $507,692.31

You use 6 gallons of water on 20 plants in your garden. At that rate, how much water will it take to water 30 plants?

Answers

9 because every ten plants is equal to 3 gallons. 30 plants are equal to 9 gallons.
tell me if if helps.

9 because if you divide 6 by 2 you get 3 and if per 10 plants you have to use 3 gallons then for 30 you'll have to use nine because 3x3 equals 9

Francois baked just enough cookies to fill all the orders at his bakery. While the cookies were cooling, a kitchen assistant knocked over a cooling rack and spilled 1 2 % , percent of the cookies onto the floor. Francois had to bake 36 more cookies to replace them.

Answers

If 36 = 12% of the cookies, the total number of cookies equals x in the following equation:
$(36)/(.12)= (x)/(1)$

So $x = (36)/(.12) = 300$ cookies in total!
