Can side d be the base for this triangle? If so, which length would be the corresponding
height? If not, explain why not.
Answer:
Yes, gStep-by-step explanation:
Any side can be chosen as base.
If d is the base, then the height is g.
g is the perpendicular to extension of d and is the distance between d and the parallel line to d that passes through opposite vertex to d.
Examine whether each of the following pair of lines AB and CD are parallel or not
Answer:
No, they are not parallel
Step-by-step explanation:
Parallel means two lines that will never touch, but if you look at B and D, you can see that they will eventually touch if you make an imaginary line going off the screen.

Paula charges $12 to shovel a driveway. She shoveled 6 driveways on Saturday and then some more on Sunday. She made $144 for the weekend. How many driveways did she shovel on Sunday? Choose two answers: one for the equation that models this situation and one for the correct answer.
A. Answer: 12 driveways I
B. Equation: 6(12 + x) = 144
C. Equation: 12(6 + x) = 144
D. Answer: 6 driveways
Answer:
C and D
Equation: you would multiply the price per driveway by the number of driveways which would be 6 + x ( 6 on Saturday and x on Sunday)
The equation would be 12(6 + x) = 144
Solve for x:
12(6 + x) = 144
Simplify:
72 + 12x = 144
Subtract 72 from both sides
12x = 72
Divide both sides by 12
X = 6
The correct options are
C. Equation: 12(6 + x) = 144
D. Answer: 6 driveways
Given that,
Paula charges $12 to shovel a driveway. She shoveled 6 driveways on Saturday and then some more on Sunday. She made $144 for the weekend.Based on the above information, the calculation is as follows:
The equation should be 12(6 + x) = 144
12(6 + x) = 144
72 + 12x = 144
12x = 72
X = 6

A business plan is centered around a circular area of distribution. The plan calls for the radius of the distribution to increase 50 miles per year. The investors have asked that the plan include a reference to the area of distribution based on the number of years in business. These functions model this plan:
Radius in y years: r(y) = 50y
Total area: A(r) = πr2; r in miles
What is A(r(y)), the total area in y years?
A(r(y)) = 50πy2
A(r(y)) = 2,500πy2
A(r(y)) = 50πr2
A(r(y)) = 2,500πr2
Answer: B. A(r(y)) = 2,500πy2
Step-by-step explanation:
The area would be A(r(y)) = 2,500πy2
What is Area of circle?Area of Circle = πr^2 or πd^2/4 in square units,
Radius: The distance from the center to a point on the boundary is called the radius of a circle. It is represented by the letter 'r' or 'R'. Radius plays an important role in the formula for the area and circumference of a circle, which we will learn later.
Diameter: A line that passes through the center and its endpoints lie on the circle is called the diameter of a circle. It is represented by the letter 'd' or 'D'.
given:
Radius in y years: r(y) = 50y
Total area: A(r) = πr2; r in miles
Now, area of circle
=πr²
=π(50y)²
=2500y²π

Find how many days late was her book
The total days late is 14 days
charges per day for first 4 days = $0.25
charges per day for the remaining days = $0.30
Total amount Annika paid = $4.00
let x = number of days of the remaining days
Total amount paid = Amount paid for first 4 days + amount paid for remaining daysAmount paid for first 4 days = $0.25 × 4
= $1
Amount paid for remaining days = 0.30 × x
= 0.30x
Total amount paid = Amount paid for first 4 days + amount paid for remaining days
4 = 1 + 0.30x
4 - 1 = 0.30x
3 = 0.30x
x = 3/0.30
x = 10 days
Total days late = 4 days + 10 days
= 14 days

FeliCa bought three movies for 9.98 each. She also bought one movie that cost half of the total of the three movies what is the total amount that Felicia spent? Thank you for helping! :)
Answer:
$44.91
Step-by-step explanation:
The question is saying that she bought 3 movies for $9.98, so you'll have to multiply 9.98 x 3 which is $ 29.94. Now, it says that she also bought a 4th movie that cost HALF OF THE TOTAL of the tree other movies. That means that you'll have to divide $29.94 by 2. 29.94/2= 14.97. So the total of the 4th movie is $14.97. You just need to add $29.94+$14.97 which equals: $44.91 in total.
$ 44.91 is the answer!

'The ratio of the weight of an object on Jupiter to its weight on Earth is 8 to 3. How much would a 120 pound person weight on Jupiter?'
Answer:
320 pound
Step-by-step explanation:
Ratio is decently easy after u understand the concept
So... This is what the question gave
Jupitar : earth
8 : 3
In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth
Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value
Jupitar : earth
8 : 3
? : 120
Now its called ratio bcuz the increase at the same pace
So now look at the earth part, u got to find out how did 3 become 120, so just divide them
120/3 = 40 , so 3 x 40 = 120
So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)
8 x 40 = 320

1. How is the Earth's population changing?
2. How many people are currently living on Earth?
3. What are some reasons why the population of the world increased so dramatically? Use examples.
4. Describe what you might find in a rural area.
5. Describe what you might find in a urban area.
Answer:
1.Every year, the world’s population is expanding by 83 million people. Right now, there are around 7.6 billion people in the world. By 2050, there will be just short of 10 billion. But population trends are wildly uneven - some countries are rapidly expanding, others are shrinking. Each scenario brings its own challenge for governments.
2. 7.6 billion - 7.9 billion people are living on earth
3.The reason why humans have increased in population so rapidly and so successfully is because we’ve sidestepped the two problems of food shortage and being knocked over by disease. That started in the industrial revolution, when there were about a billion of us, and we tapped into using fossil fuels to do large scale agriculture
4. a rural area is an open swath of land that has few homes or other buildings, and not very many people. A rural areas population density is very low. Many people live in a city, or urban area. Their homes and businesses are located very close to one another.
5. An urban area is the region surrounding a city. Most inhabitants of urban areas have nonagricultural jobs. Urban areas are very developed, meaning there is a density of human structures such as houses, commercial buildings, roads, bridges, and railways. Urban area can refer to towns, cities, and suburbs.
