m∠4= 2x°
m∠5 = (x+9)°
case one: If both lie on the same plane then,
m∠4+ m∠5 = 180°
2x+x +9° = 180°
3x+9° = 180°
3x=171°
x= 171°/3
x= 57°
so,
m∠4 = 57° x 2° = 114°
m∠5= 57°+9° =66°
case two : If the angles are on opposite side of each other then,
m∠4=m∠5
2x= x+9°
2x-x=9°
x=9°
so,
m∠4m= 2x9 = 18°
∠5= 9+9= 18°
1.) m∠4 = 2x°
[tex]→m∠4+ m∠5 = 180°[/tex]
[tex]→2x+x +9° = 180°[/tex]
[tex]→3x+9° = 180°[/tex]
[tex]→3x=171°[/tex]
[tex]→x= \frac{171°}{3}[/tex]
[tex]→x= 57°[/tex]
So,
[tex]m∠4 = 57° × 2° = 114°[/tex]
[tex]m∠5= 57°+9° =66°[/tex]
2.) m∠5 = (x+9)°
[tex]→m∠4=m∠5[/tex]
[tex]→2x= x+9°[/tex]
[tex]→2x-x=9°[/tex]
[tex]→x=9°[/tex]

A ladder is leaning up against the side of a house. Use two points
to find the slope of the ladder. Then verify that the slope is the
same at a different location by choosing a different set of points.
Answer:
The slope is 2.
Step-by-step explanation:
Slope = rise / run, meaning that when you move 2 units up, you move 1 unit right. The slope here is positive.

Dora earns a monthly salary of $2,212 plus 2% commission. Last month, she sold $19,866 worth of products. What was her gross pay?
Show work for 100 POINTS!!
====================================================
Work Shown:
2% = 2/100 = 0.02
2% of $19,866 = 0.02*19866 = 397.32
Dora earned $397.32 in commission on top of the base monthly salary of $2,212
Her total monthly pay is 2212+397.32 = 2,609.32 dollars
----------------
Optional section:
If you wanted to use a bit of algebra here, then the equation is
y = 0.02x+2212
Plug in x = 19866 and you should get y = 2609.32
Commission:-

Which operation should you perform first when you simplify 63 − (2 + 54 multiply 6) ÷ 5?
Answer:
Multiply 54 by 6
Step-by-step explanation:
Remember the Order of Operations:
Parentheses
Exponents
Multiplication/Division (Whichever comes first)
Addition/Subtraction (Whichever comes first)
In this case, we can start by looking inside of the parentheses.
There are two signs; addition and multiplication.
Now we look back to the order of operations (PEMDAS), and see that multiplication comes before addition, therefore you should first multiply 54 by 6.

Question 3
Thank youuu
Answer:
45⁰
Step-by-step explanation:
We need to find n first.
we are given that GQH is 90⁰ which means that the sum of GQL and LQK should 90⁰ because these are angles on a straight line which adds up to 180⁰.
so,
(4n-15) + 3n = 90⁰
Take the -15 to the other side after opening the brackets.
4n + 3n = 90⁰ + 15
7n = 105⁰
Divide it by 7 for both sides.
n = 15⁰
Now substitute n=15⁰ in you LQK equation.
4n -15
(4×15) -15
60⁰ - 15
45⁰

09. Find the rate A sum of money doubled itself in 15 years. In how many years will it become 8 times of itself?
Answer:
45 years
Step-by-step explanation:
Let the sum be x and CI=2x
We know that
CI=P(1+100R)T
2x=x(1+100R) ^15
(1+100R)^15=2
Let m be the number of years.
Therefore,
x(1+100R)m=8x
(1+100R)m=23
(1+100R)m=[(1+100R)^15]3
From eqn(1)
(1+100R)m=(1+100R)45
On comparing both power, we get
m=45 years
solve the following equation for x
4x - 6y=20
Answer:
x = [tex]\frac{3}{2}[/tex]y + 20
[Given]
4x - 6y = 20
[Add 6y to both sides of the equation]
4x = 6y + 20
[Divide both sides of the equation by 4]
x = [tex]\frac{6}{4}[/tex]y + 20
[Simplify [tex]\frac{6}{4}[/tex], both 6 and 4 are divisible by 2]
x = [tex]\frac{3}{2}[/tex]y + 20
A King in ancient times agreed to reward the inventor of chess with one grain of wheat on the first of the 64 squares of a chess board. On the second square the King would place two grains of wheat, on the third square, four grains of wheat, and on the fourth square eight grains of wheat. If the amount of wheat is doubled in this way on each of the remaining squares, how many grains of wheat should be placed on square 15? Also find the total number of grains of wheat on the board at this time and their total weight in pounds. (Assume that each grain of wheat weighs 1/7000 pound.)
Answer:
Square 15: 16,384
Sum of all grains up to and including square 15: 32,767
Total weight up to and including square 15: 4.681 lb
Step-by-step explanation:
Square 1: 1 = 2^0
Square 2: 2 = 2^1
Square 3: 4 = 2^2
Square 4: 8 = 2^3
Notice that the exponent of the 2 is 1 less than the number of the square, so for square n, the number of grains is 2^(n - 1)
Square n: 2^(n - 1)
Square 15: 2^(15 - 1) = 2^14 = 16,384
Now let's look at the sums.
Square 1 sum: 1
Square 2 sum: 1 + 2 = 3
Square 3 sum: 3 + 4 = 7
Square 4 sum: 7 + 8 = 15
Notice that each sum is one grain less than 2 raised to the number of the square.
Square 1 sum: 1 = 2^1 - 1
Square 2 sum: 1 + 2 = 3 = 2^2 - 1
Square 3 sum: 3 + 4 = 7 = 2^3 - 1
Square 4 sum: 7 + 8 = 15 = 2^4 - 1
Square n sum: 2^n - 1
Square 15 sum: 2^15 - 1 = 32,767
Weight:
32,767 × 1/7000 lb = 4.681 lb

A shipping container will be used to transport several 60-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 24000 kilograms. Other shipments weighing 3300 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine xx, the number of 60-kilogram crates that can be loaded into the shipping container.
((60 * c) + 3300 ≤ 24000
60c ≤ 24000 - 3300
60c ≤ 20700
c ≤ 20700 / 60
c ≤ 345
Step-by-step explanation:
60x + 3300 = 24000
60x = 24000 - 3300
60x = 20700
x = 345

calculate the length of the diagonal for the given rectangular prism. Round to the nearest tenth
Length = 10cm
Width = 4cm
Height = 10cm
The length of the diagonal of the rectangular prism is 14.7 feet to the nearest tenth.
What is a prism?In a three-dimensional space prism is a polyhedron where two ends are similar.
Given:
The dimensions of the right rectangular prism:
Length l = 10cm
Width w = 4cm
Height h = 10cm
The length of the diagonal of the rectangular prism,
= √(l² + w² + h)
= √{(10)² + (4)² + (10)²}
= 14.69
