Answer:
a = 20
Step-by-step explanation:
1/2a - 4 = 6
+4 +4
--------------------
1/2a = 10
*2 *2
---------------------
1a = 20
/1 /1
----------------------
a = 20<em> -------------------> answer</em>
Answer:
Yes they are similar. Triangle ABC is similar to Triangle FED. The scale factor from large to small is 3/4 or small to large is 4/3.
Step-by-step explanation:
To determine if two triangles are similar, their corresponding sides create equal ratios.
This ratio is the scale factor depending on which is the pre-image. 3/4 or 4/3.
Answer:3.14
Step-by-step explanation:
Volume of cylinder can be calculated by using the formula V= pir^2h
Where r is radius of cylinder and h is the height.
A cylinder with radius 1 inch and height of 1 inch is given.
r=1,h=1,π=3.14.
Substituting the given values :
V=3.14(1)^2(1)
Volume of cylinder rounded to nearest tenth is 3.14 cubic inches .
The answer is 9x - 90y = 20.
Explanation:
y = 1/10 x - 2/9
First eliminate the fractions by multiplying through by the LCM which is 90:-
90y = 9x - 20
Standard form is ax + by = c, so rearranging we get:
0 = 9x - 90y - 20
9x - 90y = 20 .
Standard form = 3.0098 × 10 power 4
Significant figures = 30100
