Answer:
if you ment to say 2 is 12.5% of what number the answer would be 16
Step-by-step explanation:
Write down what you know with x as the number you need to find.
Of is always "multiply"
Choose another way to write 12.5%
2 =12.5% of x
So 2 = 0.125xx
x= 2 *over*0.125
x=16
Answer:
22.39
Step-by-step explanation:
angle D + angle F + angle E = 180 (angle of triangle)
30 +60 + E = 180
E = 180 - 90
E = 90
so triangle DEF is right angled triangle
we know that,
sin 30 = EF /DF
OR, 1/2 = 6/ DF
OR, DF= 12
again,
cos 30 = De/DF
root3 /2 = DE /12
DE= 10.39
hence DF +DE
= 12 + 10.39
= 22. 39
Answer:
P = 18.4 units
Step-by-step explanation:
Sides AB and CD are congruent and thus have the same length.
Sides AD and BC are congruent.
The length of side AB is found using the Pythagorean Theorem:
|AB| = √ [ 5² + 1² ] = √26
and
|BC| = √ [ 4² + 1² ] = √17
Then the perimeter is P = 2(√26) + 2(√17), or
10.20 + 8.25, or, to the nearest tenth,
P = 18.4 units
Answer:
8m
Step-by-step explanation:
So 12m and 4m are both like terms which means you can add both of them together.
Since 12-4=8
12m-4m=8m
I hope this helps :)
