Answer:
-34.
Step-by-step explanation:
This is an arithmetic sequence with first term a1 and common difference -2.
nth term = a1 + d(n - 1)
23rd term = 10 - 2(23-1)
= 10 - 44
= -34.
Answer:
-34
Step-by-step explanation:
The sequence starts with 10. Each subsequent term is 2 less than the previous term.
The common difference is -2.
The second term is 10 + (-2) × 1
The third term is 10 + (-2) × 2
The fourth term is 10 + (-2) × 3
Each term you subtract a multiple of -2 from 10. The multiple is 1 less than the number of the term multiplied by -2.
For term n, you get 10 + (-2) × (n - 1).
The 23rd term is:
10 + (-2) × (23 - 1) = 10 - 2 × 22 = 10 - 44 = -34

Show that KLPQ is a parallelogram
for m = 14 and n = 12. 5. .
L
(5m + 36)
P
(6n – 1)º
(4m + 50)
K
Step-by-step explanation:
m = 14, n = 12.5
m<L = (5m + 36)° = (5(14) + 36)°
L = 106°
m<p= (6n-1°)=(6x12.5-1°)
p=74°
m<Q = (4m + 50)° = (4(14) + 50)°
Q = 106°
k=360°-(106°+74+°106°)=360°-286°
k=74°
The sum of the interior angle of a parallelogram is 360°
The opposite side of a parallelogram are equal.

Find the measure of the indicated angle to the nearest degree
Answer:
30
Step-by-step explanation:
I see that the square in the triangle is a right triangle, so it's automatically a 90 degrees. the triangle should add up to 180, so I figured that since we have 90, we just needed to find the other angles that help add up to that, which is 60 and 30
im sorry if im wrong
can someone please help me work out this question i really don't understand
Answer:
108 cm^2
Step-by-step explanation:
rectangle + 2 triangle = total area
L x W + 2 * 1/2 base * height = total area
(5x12) + 2 * 1/2 * 12 * 4 = total area
60 + 48 = 108 cm^2
Answer:
108 cm²
Step-by-step explanation:
To do:
1. find area of rectangle 2. find area of triangles 3. add them together
area of a rectangle = bxh = 5x12 = 60
area of triangle = (bxh)/2 = (12x4)/2 = 24
60+24+24=108

The balance in Hayden's savings account is $600.
What is the balance of the savings account?
Net worth is total assets less liabilities. Assets are items owned by a person that creates benefits in the future to the person. Liabilities are what are owed to another person.
Net worth = assets - liabilities
6760 = (2540 + 6000 + savings) - (880 + 1500)
6760 = 8540 + savings - 2380
Savings = 6760 - 8540 + 2380

what is 2x - 3y + 5z, x = 5 , y = one third, z =3 what does it equal
Answer:
24
Step-by-step explanation:
substitute the given values into the expression
2x - 3y + 5z
= 2(5) - 3([tex]\frac{1}{3}[/tex] ) + 5(3)
= 10 - 1 + 15
= 9 + 15
= 24
what is the answer to this equation 4x + 5y =6
Answer:
Step-by-step explanation:
This equation has no solution. You have one equation with two variables, so it cannot be solved. If you have another equation having the same variables x and y, then by using simultaneous equations, values of x and y can be solved. But to this equation 4x + 5y = 6, there is no solution for the reason mentioned above.
The combined area of a square and a rectangle is 225 square yards. the length of the rectangle is 8 times the width of the rectangle and the length of a side of the square is the same as the width of the rectangle. find the dimensions of the square and the rectangle.
Answer:
The rectangle: L = 40 yards. W = 5 yards
The square: The length and width are both 5 yards.
Step-by-step explanation:
Let L and W be the length and width of the rectangle.
Let l and w be the length and width of the square.
Area for each is:
Rectangle: L*W
Square: l*w
We are told that L*W + l*w = 225 yards^2
We are also told that
L = 8W
and that
l = W
Since the sides of a square are all equal, w is also W: w=W
Summarizing and substituting:
L*W + l*w = 225 yards^2
(8W)*W + W*W = 225 yards^2
8W^2 + W^2 = 225 yards^2
9W^2 = 225 yards^2
W^2 = 25
W = 5 feet
---------------------
Therefore, since L = 8W , L = 40 yards. W = 5 yards for the rectangle.
The square: l=W, so l = 5 yards, and thus w=5 yards
--------------------------
Check:
Do a rectangle of 40' x 5' plus a square of 5' x 5' have a total combined area of 225 yards^2?
40yd x 5yd + 5yd x 5yd = 225 yards^2?
200 yd^2 + 25 yd^2 = 225 yards^2?

6. We want to build the smallest cube possible using bricks with dimensions 8 cm - 12 cm 20 cm. How many bricks do we need?
Answer:
1200
Step-by-step explanation:
We’ll need a number that is evenly dividable by all three values: 8,12 & 15. We can develop the generic common multiple by multiplying all three numbers and get 1440. But is that the smallest common multiple? The quick and dirty way to factor the number is to divide it by it’s various elements and see what works. In this case 1440/12=120 which is the smallest common multiple of the three numbers. The smallest length is therefore 120.
In order to find how many bricks just divide (120x120x120)/(8x12x15)=1200 bricks

[tex]sum \: of \: angles\: of \: a \: polygon \: = \\(n - 2) \times 180\degree[/tex]
in the question , we've been given a five sided figure , i.e. , a pentagon.
sum of angles of a pentagon = ( 5 - 2 ) × 180°
[tex]\implies \: 3 \times 180\degree \\ \implies \: 540\degree[/tex]
thus we can say that ,
angle sum property of pentagon states that the sum of all the angles of a pentagon equals 540°.
therefore ,
Step-by-step explanation:
[tex]125\degree + 117\degree + (x + 6)\degree + x + (x - 44)\degree = 540\degree \\ \\ 125\degree + 117\degree + x + 6\degree + x + x - 44\degree = 540\degree \\ \\ 204\degree + 3x = 540\degree \\ \\ 3x = 540\degree - 204\degree \\ \\ 3x = 336\degree \\ \\ x = \cancel\frac{336}{3} \\ \\ x = 112\degree[/tex]

To find :-
The value of x in the angles of Pentagon
Given :-
Here we have been provided 5 angles in Pentagon
x°, (x - 44)°, (x + 6)°, 125°, and 117°
Solution :-
We will find the value of x with the angle sum property.
Now, we will find the sum of angles of Pentagon
there is a formula
(n - 2) × 180°
n = no. of sides of above shape
here n = 5
(5 - 2) × 180°
3 × 180° = 540°
Now will add the above given angle in the diagram and put equal to 540°.
x° + (x - 44)° + (x + 6)° + 125° + 117° = 540° (angle sum property)
[tex]3x + 204{\degree} = 540{\degree} \\ 3x = 540{\degree} -204{\degree} \\ 3x = 336{\degree} \\ x = \frac{336{\degree}}{3} \\ x = 112{\degree}[/tex]
x = 112°
further we will find further 2 angles related to x.
x - 44 = 112 - 44 = 68°
x + 6 = 112 + 6 = 118°
Result :-
The all angles of Pentagon are
125°, 117°, 118°, 112°, and 68°.
Study the following chemical equation. Identify the total number of atoms before and after the reaction. N₂ + 3H₂ → 2NH3
Before reaction, total number of nitrogen atoms is 2, also the total hydrogen atoms is 6. After the reaction, still, we have the same number of nitrogen atoms as 2, and hydrogen atoms as 6. This therefore obeys the law of conservation of mass that during a chemical reaction, matter is neither created nor destroyed.

X=?
5x-16 x+10
Answer:
The answer is x= 31
Step-by-step explanation:
(5x-16)+ (x+10)= 180 (Linear Pair)
Now, open the brackets
5x-16+x+10= 180
Arrange the like terms together
5x+x-16+10= 180
=> 6x-6= 180
=> 6x= 180+6
=> 6x= 186
=> x= 186/6 = 31
∴x= 31
