construction = divide the figure into two parts.
now we have triangle abd and bdc.
first calculate the area of abd.
area of triangle= 1/2×base ×height
area of triangle= 1/2×18×7.5
area of triangle=67.5cm²
second calculate area of bdc
area of triangle=1/2×15.6×11.7
area of triangle=91.26cm²
area of the figure=area of abd + area of bdc
area of the figure=67.5cm²+ 91.26cm²
area of figure=158.76 cm².

Solve for x
4 - ( 2x - 2) + 3x = 4(x + 5) - 3(x-2)-10
Answers
Step-by-step explanation:
4 + x + 3x = 4 ( 5x ) - 3 ( x ) - 10
4 + x + 3x = 4 + 5x - 3 + x - 10
x + 3x + 5x + x = 4 + 4 - 3 - 10
10x = 21
10x % 10 = 21 % 10
x = 2,1

a metal pipe is 77 cm long the inner diameter of the cross section is 4 cm and the outer diameter is 4.8 cm find the (i) inner curved surface area (ii) outer curved surface area (iii) total surface area
Answer with full step by step explaination
Answers
Answer:
Step-by-step explanation:
outer area=
first need to find the circumference of outer diameter
= π×4.8
= 15.079644.... cm
to find the outer curved area you would then do
= 77×15.079644
(ii) =1161.13264 cm²
inner curve area
circumference= π×4
=12.5663706.... cm
77×12.5663706
(i) =967.610537 cm²
total surface area=
as the outer and inner curved areas are already found only the top and bottom surfaces need to be
= area of larger circle
=π×4.8²
=72.382294.... cm²
smaller circle
=π×4²
=50.2654824.... cm²
72.382...-50.265
=22.1168116 x 2
=44.2336232 cm²
total surface area
(iii)= 2172.9768 cm²

Solve the equation: 12(x + 8) = 11x - 5 What is the solution?
Answers
Answer:
We conclude that the solution is:
[tex]x = -101[/tex]Step-by-step explanation:
Given the equation
[tex]12\left(x\:+\:8\right)\:=\:11x\:-\:5[/tex]
Expand 12(x + 8): 12x + 96
[tex]12x+96=11x-5[/tex]
Subtract 96 from both sides
[tex]12x+96-96=11x-5-96[/tex]
Simplify
[tex]12x=11x-101[/tex]
Subtract 11x from both sides
[tex]12x-11x=11x-101-11x[/tex]
Simplify
[tex]x=-101[/tex]
Therefore, we conclude that the solution is:

What is the constant in the algebraic expression to represent the patter below??
15,11,7,3,-1,...
Answers
Answer:
The constant in the algebraic expression to represent the pattern below is 4.
Step-by-step explanation:
Imortant Tip:
An Arithmetic sequence has a constant difference 'd' which can be determined by computing the differences of all the adjacent termsGiven the pattern
[tex]15,11,7,3,-1,...[/tex]
computing the differences of all the adjacent terms
[tex]11-15=-4,\:\quad \:7-11=-4,\:\quad \:3-7=-4,\:\quad \:-1-3=-4[/tex]
The difference between all the adjacent terms of the pattern is the same which is
[tex]d=-4[/tex]
Hence, the given pattern represents the Arithmetic sequence.
Therefore, the constant in the algebraic expression to represent the pattern below is 4.

X, Y and Z are partners in a firm in the ratio of 1/2 :1/3:1/6
Y retires from business and
X and Z purchase his share of profit in the ratio of 3:2. Find out new ratio
Answers
Answer:
6:2
Step-by-step explanation:
X share from old ratio is 1/2
Y share from old ratio is 1/3
Z share from old ratio is 1/6
Now, we are told Y retires and that X and Z purchase his shares.
Thus;
Amount X took from Y = 1/2 × 1/3 = 1/6
Amount Z took from Y = 1/6 × 1/3 = 1/18
Thus, new share of X is now; 1/6 + 1/2 = 2/3
New share of Z is now; 1/18 + 1/6 = 4/18 = 2/9
Ratio is now X:Z = 2/3 : 2/9 = 6:2
