What is m∠M? I don't exactly remember how to do this type on problem...
Answers
Answer:
m∠M=98º
Step-by-step explanation
Sum of interior angles;
3x-16+x+6+x = 180
5x = 180-6+16
5x = 190
x = 38º
Angle M;
m<M= 3x - 16 = 3(38)-16= 98º
m∠M=98º
Answer:
<M = 98
Step-by-step explanation:
The sum of the angles of a triangle is 180 degrees
< M + < N + < O = 180
3x-16 + x + x+6 = 180
Combine like terms
5x - 10 = 180
Add 10 to each side
5x-10 + 10 = 180+10
5x = 190
Divide by 5
5x/5 = 190/5
x=38
We want to find <M
<M = 3x-16 = 3*38 -16 = 114-16 =98
The pipe has a length 29cm, internal diameter 6.5cm and thickness 0.5cm. What is the Volume
Answers
Answer:
Length of pipe = 21 cm
Internal diameter = 4 cm
Internal radius = \frac{4}{2} = 2 cm24=2cm
Thickness = 0.5 cm
Outer radius = 2+0.5=2.5 cm
Volume of pipe =\pi R^2 h - \pi r^2 hπR2h−πr2h
Volume of pipe =\frac{22}{7} (2.5)^2 (21)-\frac{22}{7}(2)^2(21)=148.5 cm^3
=\frac{22}{7} (2.5)^2 (21)-\frac{22}{7}(2)^2(21)=148.5 cm^3722(2.5)2(21)−722(2)2(21)=148.5cm3
Hence The volume is 148.5 cubic cm.

As both the triangles are similar therefore the ratio of the sides will be equal
BC : CD = AC : CE
48 / 12 = AC / 20
AC = 80ft
As Triangle ABC is also a right angled triangle
Applying Pythagoras theorem to find the length of AB

What is the transformation of C(9, 3) when dilated with a scale factor of 1/3,
using the point (3, 6) as the center of dilation
Answers
The transformation of C(9, 3) when dilated with a scale factor of 1/3, using the point (3, 6) as the center of dilation would be an option B: C'(3,1).
What is Dilation transformation?A dilation transformation is a transformation that changes the size of the original figure but the shape remains unchanged.
If any figure is dilated by a scale factor k with the center of dilation as the origin.
Then the change of transformation in each of the vertices of the figure is given:
(x,y) → (kx, ky)
It is given a point C which is located at C(9,3).
Hence, here k=3
We get:
C(9,3) → C'(9×3,3×3)
C(9,3) → C'(27,9) = C'(3,1)
Hence, the transformation of C(9, 3) when dilated with a scale factor of 1/3, using the point (3, 6) as the center of dilation would be an option B: C'(3,1).

2. 1/6y+1/3(y+3)
3. 1/6y+1/6(y+12)-2
4. 1/3y+1/3(6-y)
Answers
The expression that is equivalent to 1/3y is 1/6y + 1/6(y + 12) - 1/6 * 12
How to determine the equivalent expression?The expression is given as:
1/3y
Express 1/3y as 1/6y + 1/6y
So, we have:
1/6y + 1/6y
Factor out y
1/6y + 1/6(y)
Add 0 to the above equation
1/6y + 1/6(y + 0)
Express 0 as 12 - 12
1/6y + 1/6(y + 12 - 12)
Expand
1/6y + 1/6(y + 12) - 1/6 * 12
Evaluate the product
1/6y + 1/6(y + 12) - 2
Hence, the expression that is equivalent to 1/3y is 1/6y + 1/6(y + 12) - 1/6 * 12

y = x² + 7x - 5
2x - y = -9
Answers
Answer:
x= -7, y= -5 and
x= 2, y= 13
This may also be written as (-7, -5) and (2, 13).
Step-by-step explanation:
Start by labelling the two given equations:
y= x² +7x -5 -----(1)
2x -y= -9 -----(2)
Let's solve by substitution!
Making y the subject of formula in equation (2):
From (2): y= 2x +9 -----(3)
Substitute (3) into (1):
2x +9= x² +7x -5
x² +7x -5 -2x -9= 0
x² +5x -14= 0
Factorise:
(x +7)(x -2)= 0
x +7= 0 or x -2= 0
x= -7 or x= 2
Find the respective values of y.
Substitute into (1):
y= (-7)² +7(-7) -5 or y= (2)² +7(2) -5
y= 49 -49 -5 or y= 4 +14 -5
y= -5 or y= 13
Thus, the solutions are (-7, -5) and (2, 13).

If price of 12 eggs is Rs. 192, how many eggs can be bought for Rs. 160?
Answers
Answer:
10
Step-by-step explanation:
First, divide 192 by 12, you get a unit rate of Rs. 16 per egg, then divide Rs. 160 by 16 and you get 10
The number of eggs that can be purchased at Rs. 160 is 10.
What is a division operator?The division operator ( / ) has the quotient of its operands where the left operand exists the dividend and the right operand exists the divisor.
The cost of 12 eggs = Rs. 192
The cost of 1 egg = 192/12 = Rs. 16.
The number of eggs that can be purchased is Rs. 160 = 160/16 = 10.
