Step-by-step explanation:
Given,GRAM is a parallelogram m<GMA = 66°m<GRP = 32°m<PAM = 41°Solutions:i) Since,
Angles on the same side of a transversal in a parallelogram, there sum is 180° so,
<RGM + <GMA = 180°
=> <RGM = 180° - <GMA
=> <RGM = 180° - 66°
=> <RGM = 114° (Ans)
ii) Since,
Opposite angles of a diagonal as a transversal (here RM) are equal so,
<GRP = <PMA = 32°
As we have <GMA = 66° so,
=> <GMP = <GMA - <PMA
= 66° - 32°
=> <GMP = 34° (Ans)
iii) Since,
Opposite angles of a parallelogram are equal so,
<RGM = <RAM = 114°
As we have <PAM = 41° so,
=> <GAR = <RAM - <PAM
= 114° - 41°
=> <GAR = 73° (Ans)
iv) Since,
We got <PMA = 32° and <PAM = 41°, so by angle sum property of a triangle PMA,
=> <MPA = 180° - 32° - 41°
=> <MPA = 107° (Ans)
A child has 12 blocks, of which 6 are black, 4 are red, 1 is white and 1 is blue. All blocks of the same color are identical. If the child puts the blocks in a line, how many arrangements are possible?
The arrangement of the blocks is an illustration of permutation and combination
The number of possible arrangement is 27720 ways
How to determine the number of arrangementsThe given parameters are:
n = 12
Black = 6
Red = 4
White = 1
Blue = 1
The number of possible arrangement is then calculated as:
[tex]Ways = \frac{12!}{6!4!1!1!}[/tex]

Can you please help me how to solve how to graph y=2x+6
Answer: Check out the graph below
The graph is a straight line through the points (0,6) and (1,8)
====================================
Explanation:
Plug in x = 0 to find that...
y = 2x+6
y = 2(0)+6
y = 0 + 6
y = 6
The point (0,6) is on the line
---------
Repeat for x = 1
y = 2x+6
y = 2(1)+6
y = 2 + 6
y = 8
The point (1,8) is also on the line
---------
Now plot the two points together on the same xy grid.
Draw a straight line through the two points. Stretch the line as far as you can in either direction. See below. I used GeoGebra to make the graph. It's a free graphing app.
Desmos is another useful free graphing tool. There are many options if you don't have a graphing calculator.

Answer:
if i read the question correctly the hairdresser cuts off 4 inches
Step-by-step explanation:
32 inches is the total length of her hair
so 4 inches off the total length means 32 - 4 which is 28 inches
so the hairdresser cuts off 4 inches and now she has 28 inches of hair left
The barber cut 4 inches of hair out of 32 inches of hair.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,

What is the percentage of lemons in the is group of lemons and strawberries?
Answer:
70%
Step-by-step explanation:
Total: 60
Strawberries: 18
Lemons: 42
[tex]\frac{42}{60}[/tex] = [tex]\frac{7}{10}[/tex] = 70%
The percentage of lemons in the group is equal to 70%.
What is the percentage?The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.
Given that in the image there are 60 objects in total, the number of lemons is 42 and the number of strawberries is 18.
Total: 60
Strawberries: 18
Lemons: 42
The percentage of the lemons will be calculated as,
Percentage = 42 / 60
Percentage = 0.7
Percentage = 0.7 x 100 = 70%
Therefore, the percentage of lemons in the group is equal to 70%.

Gina bought x cans of peas for $0.85 each and yvcans of corn for $0.78 each. She boguth 2 more cans of peas than cans of corn. The total was $6.59. How many cans of oeas and cans of corn dis she buy?
I ONLY NEED THE EQUATION...I can get the numbers of cans and peas I just need the equations to find the numbers
This is Algebra....please help me!!
Answer:
Step-by-step explanation:
Number of cans of peas = x
Cost of 'x' cans of peas = x *0.85 = 0.85x
Number of cans of corn = y
Cost of 'y' cans of corn = 0.78*y = 0.78y
Number of cans of peas = number of cans of corn + 2
x = y + 2 --------------(I)
x - y = 2 ----------------(II)
Total cost = $ 6.59
0.85x + 0.78y = 6.59 -------------(III)
Substitute x = y +2 in equation (III)
0.85(y + 2) + 0.78y = 6.59
0.85y + 1.70 + 0.78y = 6.59
0.85y + 0.78y = 6.59- 1.70
1.63y = 4.89
y = 4.89/1.63
y = 3
Number of cans of corn = 3
Plugin y = 3 in equation (I)
x = 3 + 2
x = 5
Number of cans of peas = 5
Find two consecutive odd integers whose squares add up to 290.
Answer:
11, 13
Step-by-step explanation:
Let one of the odd positive integer be x , then the other odd positive integer is x+2.
Their sum of squares:
[tex]x^{2} +(x+2)^{2}[/tex]
[tex]x^{2} +(x+2)(x+2)[/tex]
[tex]x^{2} +x^{2} +4x+4[/tex]
[tex]2x^{2} +4x+4[/tex]
Given that their sum of squares = 290
[tex]2x^{2} +4x+4 =290[/tex]
[tex]2x^{2} +4x = 286[/tex]
[tex]2x^{2} +4x -286 = 0[/tex]
[tex]x^{2} +2x -143 =0[/tex]
[tex]x^{2}+13x-11x-143 =0[/tex]
[tex]x(x+13)-11(x+13)=0[/tex]
[tex](x+13)(x-11)=0[/tex]
Therefore x = 11, x=-13
We take positive value of x:
So, x =11 and (x+2)= 11+2=13
Therefore , the odd positive integers are 11 and 13

Answer:
x = 115° , y = 65° , z = 115°
Step-by-step explanation:
The figure is a parallelogram.
Consecutive angles are supplementary ( sum to 180° ) , then
x + 65° = 180 ( subtract 65° from both sides )
x = 115°
Opposite angles are congruent , then
y = 65°
z = x = 115°
Please answer this I’m tired as hell and I just want this to be over with
I've attached some theories related to angles have a look at it
Angle y and angle KJF are co-interior angles so they add up to 180°
132 + y = 180
y = 180 – 132
y = 48
y + z = 143 ( alternate angles )
48 + z = 143
z = 143 – 48
z = 95

Answer:
D. 60°
Step-by-step explanation:
The interior angles of all triangles add up to 180 degrees.
There are two y's on the triangle
And one of the degree lengths is 60°, so we do:
2y + 60 = 180
Subtract 60 from both sides
2y + 60 - 60 = 180 - 60
2y = 120
Divide 2 from both sides
2y/2 = 120/2
y = 60°
Also, In geometry, an equilateral triangle is a triangle in which all three sides have the same length. In the familiar Euclidean geometry, an equilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.
All three sides are equal
All the three interior angles are equal to 60 degrees
The interior angles of all triangles add up to 180 degrees.
