Mary wants to find the area of the rectangle below.How many unit squares with side length 1/6 yard would mary be able to use to tile the rectangle?

Please Help Me!!! This is really important

Answers

so first find the area
area=legnth times width
area=5/6 times 1/6
5/6 times 1/6=5/36
area=5/36 square units

tile=side legnth 1/6
area of tile=legnth times width or legnth times legnth
1/6 times 1/6=1/36
we must find how many times 1/36 goes into 5/36
divide 5/36 by 1/36
5/36 divided by 1/36=5/36 times 36/1=5/1 times 36/36=5/1 times 1=5

the answer is 5 unit squares needed to tile

A 14 foot ladder is used to scale a 13 foot wall.At what angle of elevation must the ladder be situated in order to reach the top of the wall?

Answers

The angle of elevation must be 68.202 degrees

Solution:

Given that, 14 foot ladder is used to scale a 13 foot wall

We have to find the angle of elevation must the ladder be situated in order to reach the top of the wall

The figure for this solution is attached below

The ladder, wall and the ground forms a right angled triangle

ABC is a right angled triangle

AB is the height of wall = 13 feet

AC is the length of ladder = 14 feet

We have to find the angle of elevation

Let the angle of elevation be "x"

For right angled triangle ABC, We can use the definition for sine

$\sin x=\frac{\text { opposite }}{\text { hypotenuse }}$

Here, in figure, opposite = AB and hypotenuse = AC

$\sin x=(A B)/(A C)\n\n\sin x = (13)/(14)\n\n\sin x = 0.9285\n\nx = sin^(-1)(0.9285)\n\nx = 68.202$

Thus the angle of elevation must be 68.202 degrees

The angle of elevation the ladder will be situated in order to reach the top of the wall is 68°.

What is a right triangle?

A right triangle has one of its angles as 90 degrees. The angle of elevation can be found using trigonometric ratios.

Therefore, the angle of elevation can be calculated as follows;

The length of the ladder is the hypotenuse.

The opposite side is the height of the wall.

Therefore,

sin ∅ = opposite / hypotenuse

sin ∅ = 13 / 14

∅ = sin⁻¹ 0.92857142857

∅ = 68.2129901712

∅ = 68°

What is (-7/10+0.15) divided by (-0.125)

Answers

first we make -7/10 into decimal (-0.7)
then we can do 2 things
1. simplif parenthasees then divide
2. split into 2 fractions then add

I like first one better
(-0.7+0.15)/-0.125)
simplify partnehasees
-0.70+0.15=-0.55
nwe we have
-0.55/-0.125=4.4 (remember that (-)/(-)=(+)

answer is 4.4
