Answer:
2/4 = 0.5
0.578
Step-by-step explanation:
so sin(π/4) is √2/2 squaring this gets your first answer
second answer is just plug and chug in a calculator
1. write 1/2 and 1/3 as fractions with a common denominator.
the common denominator must be a multiple of both 2 and 3, for example 6, 12, 24 etc...
let the common denominator be 24
(1/2)(12/12)=12/24
(1/3)(8/8)=8/24
2. so , 9/24, 10/24, 11/24 are all fractions between 1/2 and 1/3
Answer:
Step-by-step explanation:
Look at the picture.
ΔADC and ΔCDB are similar (AA). Therefore the sides are in proportion:
We have:
Substitute:
<em>cross multiply</em>
<em>divide both sides by 12</em>
Answer:
x = 3
Step-by-step explanation:
4 ( x - 7 ) = -6x + 12
→ Expand brackets
4x - 28 = -6x + 12
→ Add 6x to both sides
10x - 28 = 12
→ Add 28 to both sides
10x = 30
→ Divide both sides by 10
x = 3
