Answer 2

Answer:

Hey there! :D This is a ratio so basically ratios and fractions are the same things! So lets set it up first we do 56/8=7 and 72/8= 9. Also when you are dividing fractions you always have to divide by the same number. So your answer is 7/9.

Hope I helped! ;)

−5/19x>−3

Answers

it could be 2 things
(-5/19)x>-3 or
-5/(19x)>-3
if it is the first one, go to AAAAAA
if it is second one go to BBBBBBB

(-5/19)x>-3
multiply both sides by -19/5 to clera fraction (-5/19 times -19/5=-95/-95=1)
x>-57/5
x>-11 and 2/5

BBBBBBBBB
-5/(-19x)>-3
multiplyboth sides by -19x
-5>57x
divide both sides by 57
-5/57>x

if it is $(-5)/(19)$ x>-3 then x>-57/5
if it is $(-5)/(19x)$ >-3 then x<-5/57

The measure of angle A is 4 degrees greater than the measure of angle B. The two angles are complementary. Find the measure for each angleThe measure of angle D is 5 times the measure of angle E. The two angles are supplementary. Find the measure of each angle.

Answers

Given:
Angle A is 4 degrees greater than the measure of Angle B. Both angles are complementary

Complementary angles have a sum of 90°

Angle A = x + 4° ; Angle B = x

x + 4° + x = 90°
2x = 90° - 4°
2x = 86°
x = 86° ÷ 2
x = 43° ANGLE B.

Angle A = x + 4° ⇒ 43° + 4 = 47°

Given:
Angle D is 5 times the measure of Angle E. These angles are supplementary. This means that their sum is 180°

Angle D = 5x ; Angle E = x

5x + x = 180°
6x = 180°
x = 180° ÷ 6
x = 30° Angle E.

Angle D = 5x = 5(30) = 150°

Angle D is 5 times greater than Angle E. These angles is supplementary. This means that their sum is 180°

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.
