Answer:
30
Step-by-step explanation:
Answer:
1.) B.) 30
2.) D.) 2.38
Step-by-step explanation:
1.) The answer is B because when the encyclopedia first went live there were 30 articles in it.
2.) The answer is D because the product first started out as $38⁰⁰ and each year it is decreasing half the amount of the year before it and it does this for 4 years:
Start: Year 1: Year 2: Year 3: Year 4:
$38⁰⁰ ÷ 2 = $19 ÷ 2 = $9⁵⁰ ÷ 2 = $4⁷⁵ ÷ 2 = $2³⁸ <--- I rounded up because 2.375 is closer to 2.38

Estimate 154 divide 7
Answers
Answer:
22
Step-by-step explanation:
The result of 154 divided by 7 will be 22.
What is the rule of division?The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.
Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.
Since the given problem is not a large division. We can solve it by breaking 154 into two parts
______
7 / 154 \ 2 2
14
---------
1 4

Therefore, 22 will come from dividing 154 by 7.

The radius of a circle is 3 m. Find its circumference in terms of pi
Answers
Gotcha, bro.
(I don't know what pi is, so I'm gonna assume that it is 3.14)
C=pi x diameter
First, multiply the radius by 2 so you have the diameter.
3x2=6
Second, multiply 3.14 (pi) by 6 (diameter)
3.14x6=18.84
Therefore, the circumference is 18.84.
(19 if you round it to the whole number)
Hope this helps!

The circumference of the circle is 6π meters.
What is a circle?A circle is a two dimensional figure with a radius and circumference of 2πr.
We have,
The circumference of a circle is given by the formula:
C = 2πr
where r is the circle's radius and π (pi) is a mathematical constant approximately equal to 3.14.
In this case, the radius of the circle is 3 meters.
Substituting this value in the formula, we get:
C = 2πr
C = 2π(3)
C = 6π
Therefore,
The circumference of the circle is 6π meters.

Taylor earns $5 each time she walks her neighbor's dog.she has already earned $25.write and solve an equation to find out how many more times taylor needs to walk the dog to earn enough to buy a bike that cost $83.
Answers
Answer:
Equation: $83=5w+25 and 12 walks more
Step-by-step explanation:
Here is an equation: $83=5w+25
The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)
The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.
The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)
To solve:
83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone
58 = 5w –– Divide both sides by 5 to get w alone
11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)
Check:
83=5w+25 –– Replace w with 12
83=5(12)+25 –– Multiply
83=60+25 –– Add
83=85 –– This shows she will have $2 left over

Answers
there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6.
What is the combination?
In simple words, combination involves the selection of objects or things out of a larger group where order doesn't matter. The formula for combination helps to find the number of possible combinations that can be obtained by taking a subset of items from a larger set.
There are a total of 6 players in the round-robin racquetball tournament, which means that each player will play a set against each of the other 5 players.
To determine the total number of sets that need to be played, we can use the combination formula:
nC₂ = (n*(n-1))/2
where n is the number of players.
In this case, n = 6, so:
6C₂ = (6*(6-1))/2 = 15
Hence, there are 15 sets that need to be played in the tournament. To list all the sets, we can simply list all the possible combinations of 2 players from the group of 6:

A 9-foot ladder leans against a building six feet above the ground. At what height would a 15-foot ladder touch the building if both ladders form the same angle with the ground?
Answers
Answer:
10
Step-by-step explanation:
You make a proportion 9/6=15/x then multiply 6 and 15 and divide it by 9
The height the 15 ft building touches the building is approximately 10 ft.
The ladder is 9 ft tall and leaning on a wall that is 6 ft above the ground.
The situation forms a right angle triangle.
Properties of a right angle triangle:One of it angle is equals to 90 degrees.The sides and angles can be found using trigonometric ratios.Therefore, let's find the angle made by the 9 ft ladder and then use it to find the height the 15 ft ladder touch the building.
Using trigonometric ratios,
let
∅ = angle
tan ∅ = opposite / adjacent
tan ∅ = 6 / 9 = 2 / 3
∅ = tan⁻¹ 0.6666666
∅ = 33.6900672615
Therefore, the height the 15 ft ladder touch building can be calculated as follows:
tan 33.69 = h / 15
h = 15 × 0.66666496431
h = 9.99997446476
h ≈ 10 ft.
