For step b. would be 44 divided by 19 = b for step c you can answwer seeing i gave you the equation and along with question a do things you know first then you might have the answers for the rest i hope this helps
Answer:
length = 27
breadth = 16
Step-by-step explanation:
The equation to determine the perimeter of the rectangle is given as
6x-10=86
the solution to above is x=16
Hence one of the side is 16. The formula for perimeter is given as
P=2(l+b)
if b=x =16
and P=86
replacing them inthe formula for perimeter
86=2(l+16)
dividing both sides by 2 we get
43=16+l
subtracting 16 from both sides we get
27=l
Hence the length and breadth of the rectangle are 27 and 16 respectively
Area of a triange = 180 degrees
60 + 90 + 30= 180
180-30=150
Z=150 degrees
Answer:
18
Step-by-step explanation:
( 3 + √3 ) ( 5 - √2 )
= 3 ( 5 - √2 ) + √3 ( 5 - √2 )
= 15 - 3√2 + 5√3 - √6
√2 = 1.41 ( approximately )
3√2
= 3 x 1.41
= 4.23
√6 = 2.44
√3 = 1.73
5√3
= 5 x 1.73
= 8.65
15 - 3√2 + 5√3 - √6
= 15 - 4.23 + 8.63 - 2.44
= 15 + 8.63 - 4.23 - 2.44
= 15 + 8.63 - 6.67
= 15 + 1.93
= 16.93
Rounding of 16.93 = 17
17 is near to 18.
So, 18 can be the answer.
Let the sisters have dollars in the amounts of a,b,c.
<span>After the youngest splits half of hers with the others, they have </span>
<span>a/2, b+a/4, c+a/4 </span>
<span>After the middle gives each of the others 4, they have </span>
<span>a/2 + 4, b+a/4 - 8, c+a/4 + 4 </span>
<span>After the eldest splits half of hers with the others, they have </span>
<span>a/2 + 4 + (c+a/4 + 4)/4, b+a/4 - 8 + (c+a/4 + 4)/4, (c+a/4 + 4)/2 </span>
<span>Now they all have 16. </span>
<span>a/2 + 4 + (c+a/4 + 4)/4 = 16 </span>
<span>b+a/4 - 8 + (c+a/4 + 4)/4 = 16 </span>
<span>(c+a/4 + 4)/2 = 16 </span>
<span>substituting in the last expression, we have </span>
<span>a/2 + 4 + 8 = 16 </span>
<span>b + a/4 - 8 + 8 = 16 </span>
<span>c/2 + a/8 + 2 = 16 </span>
<span>a = 8 </span>
<span>b = 14 </span>
<span>c = 26</span>
