Answer:
b. 156
Step-by-step explanation:
180 - 29 = 151
x-5=151
x=151+5
Answer:
x = 156
Step-by-step explanation:
A straight line has an angle of 180 degrees. Subtract the known angle from 180:
180 - 29 = 151
The missing angle is 151 degrees. The value of x is 5 more, given 151 = ( x - 5 ).
151 + 5 = 156.
x = 156.

Vertical angles theorem states that vertical angles are congruent.
Arcs EF and are intercepted by vertical angles, therefore:

mABD = mAB + mBDCentral angle has same measure with intercepted arc.
mBD = m∠BCD = 21°So the arc ABD is:

a) Harry books a taxi online and travels 12 miles.
He pays £29.48 altogether.
How much is the charge for booking online?
b) If Sue books online and travels 20 miles, what will be
Answers
Answer:
£b = £1.68
A = £44.68
Step-by-step explanation:
Given:
A = 5 + 1.9m + b
Where,
A = total cost
m = number of miles travelled
£b = charge for booking online
£5 = fixed charge
A. Harry
A = £29.48
m = 12 miles
£b = ?
A = 5 + 1.9m + b
29.48 = 5 + 1.9(12) + b
29.48 = 5 + 22.8 + b
29.48 = 27.8 + b
29.48 - 27.8 = b
b = 1.68
£b = £1.68
b) If Sue books online and travels 20 miles, what will be
A = 5 + 1.9m + b
= 5 + 1.9(20) + 1.68
= 5 + 38 + 1.68
= 44.68
A = £44.68

Answer:
x = 2.2, y = 5.3
Step-by-step explanation:
This question is asking us to solve a system (find x and y). Because they give us that y = 1.5x + 2, then we can use this to substitute into the second equation.
9x + 4y = 41
9x + 4(1.5x + 2) = 41
Simplify.
9x + 6x + 8 = 41
15x + 8 = 41
Subtract 8 from both sides.
15x = 33
Divide both sides by 15.
x = 11/5 = 2.2
To find y, substitute x = 2.2
y = 1.5x + 2
y = 1.5 * 2.2 + 2
y = 3.3 + 2
y = 5.3
Now, we can double check to see if these two answers are right. Plug these numbers into the other equation (because to find y, we already used the first equation, so there is no need to check it, as it would just give us 5.3 = 5.3)
9x + 4y = 41
9 * 2.2 + 4 * 5.3 = 41
19.8 + 21.2 = 41
41 = 41
Thus, the answer is correct.

The Great Wall of China is about 20 feet high and abiut 15 feet wide what is the volume of a 1-mile section of the wall? (The whole wall is more than 5,000 miles long!)
Answers
Answer:
79200 feet is the volume of great wall.
Step-by-step explanation:
1 mile = 5280 feet
5280 feet × 15 feet = 79200
The height is the thing that we don't need to use, because you need volume, volume is the place where the wall at, the place is 79200 feet.
And I have question for you, have you ever go to China, did you go to the great wall, where did you come from.
So a 1-mile section of the Great Wall of China has a volume of 1,584,000 cubic feet.
What is volume?Volume is a measure of the amount of space occupied by a three-dimensional object or substance. It is typically measured in cubic units such as cubic meters, cubic centimeters, or cubic feet.
The volume of an object is determined by measuring the length, width, and height of the object and then multiplying these three dimensions together.
To calculate the volume of a 1-mile section of the wall, we need to first calculate the area of the wall in square feet, and then multiply it by the length of the 1-mile section.
The area of the wall can be calculated as the product of its height and width:
Area = Height x Width = 20 feet x 15 feet = 300 square feet
To convert the 1-mile distance to feet, we need to multiply it by the number of feet in a mile:
1 mile = 5280 feet
Therefore, the volume of a 1-mile section of the wall can be calculated as:
Volume = Area x Length = 300 square feet x 5280 feet = 1,584,000 cubic feet
So a 1-mile section of the Great Wall of China has a volume of 1,584,000 cubic feet.

2x+2y=-2
3x-2y=12
What is this please
Answers
Answer:
x=2, y=-3
Step-by-step explanation:
This type of problems is called a system of equations, or simultaneous equations.
When solving simultaneous equations, you need to first make sure you have two unknown terms of the same number but different signs - this is so one unknown cancels out because we can only solve when there's one unknown. We already have this ('2y' and '-2y'). Now we just add the 'x's, the 'y's and the numbers:
2x+2y=-2
3x-2y=12
(2x+3x)+(2y-2y)=(-2+12)
5x=10
x=2
Now that we know the value of x, use it to find y:
2x+2y=-2
2(2)+2y=-2
4+2y=-2
2y=-6
y=-3

Answer:
m<YVX = 49°
Step-by-step explanation:
Given:
m<YVZ = 52°
m<ZVW = 36°
m<XVU = 43°
m<YVX + m<YVZ + m<ZVW + m<XVU = 180° (angles in a straight line)
m<YVX + 52 + 36 + 43 = 180 (substitution)
m<YVX + 131 = 180
m<YVX = 180 - 131
m<YVX = 49°

What is the area of the front face?
Answers
Answer:
the area of the front face would be 40 square inches.
Step-by-step explanation:
to find the are of a rectangle, you multiply the length times the width. we can see that the length is 8 inches at the bottom of the front face and we can see that width is 5 inches next to the left side face. if we take those two numbers (5 and 8) and multiply them, we get 40. all you have to do after that is add "square inches" to the end because when you find the area of something, it will be squared and the measurement used in inches.

Answers
Answer:
i. Average velocity = 11.11 m/s
ii. Displacement of the bus is 20000 m due east.
Step-by-step explanation:
The displacement of an object is the distance covered towards a definite direction, while the velocity of an object is the rate of its displacement in a given time.
average velocity = [tex]\frac{displacement}{time taken}[/tex]
But,
20 km = 20 000 m
30 minutes = 30 x 60
= 1800 s
So that,
average velocity = [tex]\frac{20000}{1800}[/tex]
= 11.1111
average velocity = 11.1 m/s
The displacement of the bus is 20 km due east.
