La of sine:
sinC/c = sinB/b==> sin 37°/8 = sin B/12 ==> sin B = 0.903
arcsinB or sin⁻¹ B = 64.5°, & sin (B°) = sin (180° - B°), then
sin(64.5) = sin(180°-64.5°) ==> B = 64.5° or 115.5°
Answer:
$0.3
Step-by-step explanation:
8.90x2=17.8
1.75x2=3.5
17.8+3.5=21.3
21.90-21.3=0.6
0.6/2=0.3
Cost of kg of apples = £1.08
cost of an orange = £0.12
hi, the solution is in the pic below. sorry for the messy working!
Answer:
The other parenthesis, but if that was a typo then I'm not sure. Hope this helps! :)
Step-by-step explanation:
To add or subtract fractions , their denominator ( The one beneath the numerator, the one that divides the numerator ).
If they both terms have the same denominators you just have to add or subtract their numerators and stay with your denominator:
example: 3/5 + 4/5 = 7/5
2/3 - 1/3 = 1/3
But if the terms you are adding or subtracting do NOT have the same denominator , you have to make their denominator equal by equivalency :
Example : 2/3 + 1/6
I cant add 2/3 to 1/6 because they have different denominators. But if I multiply 2/3 by 2/2 it wil be 4/6:
4/6 + 1/6 = 5/6 !!
As 2/2 = 1 , I did not change the value but I changed the numerator and denominator of 2/3 :
If I multiply the numerator of a fraction by any number , but I do the same thing to the denominator, It creates a equivalency, where I dont change the actual values of the fraction.
I hope you understood my brief explanation , and please consider marking this awnser as Branliest if you think it deserves it. Thank you ! :)
