Answer:
0.8
Step-by-step explanation:
20÷25=4÷5=0.8
Well, in order to first determine the slope or y-intercept, you must put change the equation to this format: y=mx+b.
m=slope and b=y-interceptI
in order to do that, you must change this equation.
x+3y=9
-x -x
----------
3y=9-x
Then, rewrite it as:
3y=-x+9
_______
3 3
simplify to
y=-x/3 +9
Answer:
1. m ∠ 1 = 113°
2. m ∠ 2 = 67°
3. m ∠ 4 = 67°,
4. m ∠ 5 = 113°
5. m ∠ 6 = 67°
6. m ∠ 7 = 113°
7. m ∠ 8 = 67°
Step-by-step explanation:
Given AB║CD and m║n and m∠3=113°
Solution, since m and n are parallel lines so AB and CD are transversal lines.
So ∠2 and ∠3 makes a linear pair whose sum is equal to 180°.
(∠2 and ∠8),(∠3 and ∠7),(∠1 and ∠5),(∠4 and ∠6) are alternate interior angles.
(∠2 and ∠4),(∠1 and ∠3),(∠5 and ∠7),(∠6 and ∠8) are corresponding angles.
When two lines are parallel and their is a transversal line then the measure of alternate angles are equal and also the measure of corresponding angles are equal.
Hence the measure of all angles are:
1. m ∠ 1 = 113°
2. m ∠ 2 = 67°
3. m ∠ 4 = 67°,
4. m ∠ 5 = 113°
5. m ∠ 6 = 67°
6. m ∠ 7 = 113°
7. m ∠ 8 = 67°
Answer:
240 cm^2
Step-by-step explanation:
Comment
There are 2 ends that are in the shape of a triangle
There is 1 base that is rectangular
There are 2 roof tops that are rectangular in shape.
Find the area of the triangles, base, 2 roof parts.
Solution
<em>1 base</em>
w = 4 cm
L = 12 cm
Area = L*w
Area = 12*4
Area = 48 cm^2
<em>Two Triangles</em>
B = 4 cm
H = 6 cm
Area = 1/2 b * h
Area = 1/2 6 * 4
Area = 12 cm
But there are 2 triangles
Area 2 triangles 24 cm^2
<em>Two roof tops</em>
L = 12 cm
w = 7 cm
Area = L*w for one roof top
Area = 12*7 cm
Area = 84 cm^2
But there are 2 of them <u> 168 cm^</u>2
Total Area 240 cm^2
Answer:
= 24 3/4x
Step-by-step explanation:
3* 8 1/4x
Here 8 1/4 is a mixed fraction.
Convert it to improper fraction
8 1/4 = 33/4
So, 3*33/4 x
99/4 x
= 24 3/4x
That is
Hope this will helpful.
