Answer:
46.84
Step-by-step explanation:
Add the decimals first to get .84 then add the real numbers to get 46.
Answer:
y = 9
Step-by-step explanation:
Calculate the slope m of line k using the slope formula
m = (y₂ - y₁ ) / (x₂ - x₁ )
with (x₁, y₁ ) = (5, 8) and (x₂, y₂ ) = (2, y)
m = 
= 
Given a line with slope m then the slope of a line perpendicular to it is
= - 
The slope of line l is m = 3, thus slope of line k is
m = - 
Equating the 2 slopes for line k
= - ( multiply both sides by - 3 )
y - 8 = 1 ( add 8 to both sides )
y = 9

Step-by-step explanation:
Remark
This may be a little late, but it is well worth finding all the answers. It is a perfect test question.
You should solve the angles in this order 2 5 1 4 3. This is not the only order you could use.
Angle 2
<180 = <2 + 148 <2 and 148 are supplementary
<180- 148 = <2
<2 = 32
Angle 5
1) All triangles have 180 degrees.
2) Diagonal bisect each other and are equal.
3) The two sides (one of which is opposite angle 5 are equal.
x + x + 148 = 180 All triangles have 180 degrees
All rectangles have diagonals that are bisected and the bisected parts are equal.
2x + 148 = 180 Subtract 148
2x = 180 - 148
2x = 32 Divide by 2
x = 32/2
x = 16
But x is really <5
<5 = 16
Angle 1
<1 = <5 by the z property of angles associated with parallel lines.
Angle 4
Angle 4 and <5 are Complementary. They make up 90 degrees.
Angle 3
<2 + the two base angles in the triangle = 180 degrees
The two base angles are equal. Call them x.
x + x + 32 = 180
2x + 32 = 180 Subtract 32 from both sides
2x = 180-32
2x = 148 Divide by 2
x = 148/2
x = 74
<3 = 72
Answer:first fine the perimeter 42cm then do the lenth then width and u get the answer

Answer:
4/5
Step-by-step explanation:
You can remove the trailing 0s, and you have 0.8
this is equal to 8/10
8 and 10 can be divided by 2
8÷2=4
10÷2=5
thus, you get 4/5
