The density of an object is the ratio of the mass of the object to its volume. The height of the block of sugar maple is 6cm
Density of an objectThe density of an object is the ratio of the mass of the object to its volume. Mathematically;
Density = mass/volume
Given the following
Mass of block = 82.8grams
Density = 0.69g/cm^3
volume = lwh
Volume = 20h
Substitute
0.69 = 82.8/20h
20h = 82.8/0.69
20h = 120
h = 6cm
Hence the height of the block of sugar maple is 6cm

Two digits of the 6-digit number X = 345 * 8* are missing. Fill in the missing digits
so that the number obtained is the smallest possible number that is divisible by 45.
Find X.
The smallest possible number that is divisible by 45 when the blanked place of the number is filled is 345285.
What is the divisible rule of 9 and 5?The divisible rule of 9 and 5 are:
Divisible rule of 9- When the addition of all number is divisible by 9, then that number also divisible by 9.Divisible rule of 5- When a number has a digit 0 or 5 in the last of it, then that number also divisible by 5.Two digits of the 6-digit number are missing.
[tex]X = 345 * 8*[/tex]
The smallest possible number from this is divisible by 45. The factors of 45 are 9 and 5.
[tex]45=9\times5[/tex]
Thus, the 6-digit number which is divisible by 45, must be divisible by 9 and 5.
To be divisible with 5, the number has 0 or 5 in last. So the numbers can be,
[tex]X = 345 * 85\\X=345 * 80[/tex]
For first number, when the blank is filled with number 2 to make sum 9 and for second the blank number should be 7. Thus, the numbers,
[tex]X = 345 285\\X=3457 80[/tex]
Thus, the smallest possible number that is divisible by 45 when the blanked place of the number is filled is 345285.

The flight path of a rocket, launched from the ground, is modeled by y = 0.5(20x – x2), where y is the height of the rocket in feet from the ground and x is the time in seconds after it was launched. Find the vertex of the parabola and explain what it represents in terms of the context.
a. (20, 0); rocket lands at 0 feet after 20 seconds
b. (10, 50); rocket reaches maximum height of 50 feet after 10 seconds
c. (10, 50); rocket reaches maximum height of 10 feet after 50 seconds
d. (20, 0); rocket reaches 20 feet after 0 seconds
Answer: B. (10, 50)
Step-by-step explanation:
y = 0.5(20x - [tex]x^{2}[/tex])
[tex]y=-\frac{1}{2} x^{2} + 10x[/tex]
to find x coord of vertex use the equation
[tex]\frac{-b}{2a}[/tex]
[tex]x=\frac{-10}{-1} \\\\x=10[/tex]
plug in x to the original equation
y = 0.5(20(10) - [tex](10)^{2}[/tex]

All triangles have 180 degrees. In this triangle, there is 1 ninety degree angle. The other two are related.
Equation
x + x + 10 + 90 = 180 Combine the left
Solution
2x + 100 = 180 Subtract 100 from both sides
2x+100-100 = 180-100
2x = 80 Divide by 2
2x/2 = 80/2
x = 40
Answer
x = 40
x + 10 = 40 + 10 = 50

Answer: Commutative Property of Addition
Explanation:
This is the rule which says that we can add two numbers in any order.
For example, 3+2 = 2+3 since both sides result in 5. The rule can be extended to involve variables, because variables are placeholders for actual numbers. Also, the rule can be extended to any number of terms and not just two.
A more generalized form of the rule could be something like x+y = y+x

Answer the question below. Type your response in the space provided. Polygon ABCD is translated to create polygon A′B′C′D′. Point A is located at (1, 5), and point A′ is located at (-2, 1). What is the distance from B to B′ ?
The distance from B to B is 5.
This is because the distance between the original and new coordinates would remain the same. This is because it is done by translation and not because of the rotation. The distance between the two will still remain as 5.

Step-by-step explanation:
work in reverse (include dollar sign in your answer, I can't get it on my keyboard)10 + 2 = 1212 x 2 = 2424 + 14= 38-2x + 4y = 12
5x - 2y = 10
To answer please type altogether with no spaces. For example if your answer is negative three positive four, type (-3,4)
Answer:
(4,5)
Step-by-step explanation:
-2x + 4y = 12
5x - 2y = 10
make them both set to y
4y = 2x + 12 -> y = 1/2x + 3
2y = 5x - 10 -> y = 5/2x - 5
since they're both equal to y, they are equal to each other
1/2x + 3 = 5/2x - 5
2x = 8
x = 4
plug it back in to get y
y = 1/2 (4) + 3
y = 5

What is the product of 0 and any number?
Answer:
It will always be 0 because the rule is anything times 0 is 0
Answer:
0
Step-by-step explanation:
Hey there!
The product of any number and 0 is zero
To explain why this is, just think of it visually
So lets say we are visually explaining 7 x 3
Here is a visual explanation
There are 7 strawberries
You take 7 more strawberries
You take 7 more strawberries again
This means that you are taking 7 strawberries 3 times thereby forming the equation, 7 x 3
Now lets say a numeber [tex]x[/tex] times zero is equal to what
Well we can visualize this again
There are [tex]x[/tex] strawberries in a group
You are taking zero of those groups
Meaning there are no groups
So if there are no groups
There are no strawberries
Meaning [tex]x[/tex] times zero is zero
Since [tex]x[/tex] is any number, the statement, the product of 0 and any number is 0 is true
This is why the product of 0 and any number is 0

Estimate 17.26+4.556 by first rounding each number to the nearest tenth. I need help
Answer:
21.9
Step-by-step explanation:
When rounding to the nearest tenth, we are rounding to 1 decimal place.
If the number in the hundredth place is 5 or more, we round up.
If the number in the hundredth place is less than 5, we round down.
17.26 rounded to the nearest tenth is 17.3
as 6 is in the hundredth place, so we round 2 tenths up to 3 tenths.
4.556 rounded to the nearest tenth is 4.6
as 5 is in the hundredth place, so we round 5 tents up to 6 tenths.
Therefore, 17.3 + 4.6 = 21.9
Mrs. norris is assigning the line up of the trumpet players in the parade. tell whether the events are dependent or independent. explain your answer.
event a: kadonna is chosen to be the first trumpet player in line
event b: jerome is chosen to be the second trumpet player in line
a: the choice of the first trumpeter does not affect the choice of the second, so the events are independent.
b: the choice of the first trumpeter does not affect the choice of the second, so the events are dependent.
c: the person chosen to be first cannot also be second, so the events are independent.
d: the person chosen to be first cannot also be second, so the events are dependent
The event A is an independent event while the event B is a dependent event.
How to find dependent or independent events?
An independent event is one that is not affected by the occurrence of other events while a dependent event is one that is affected by the occurrence of another event.
Event A is an independent event because the first player does not have to wait for any player before he plays.
However, event B is a dependent event as Jerome has to wait for for the first player to play before he can play.

The experimental probability that the next train to pull in will be full is [tex]\rm \frac{4}{5}[/tex]. Probability is the ratio of the favorable event to the total number of events.
What is probability?Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1. Its basic meaning is something is likely to happen.
The experimental probability that the next train to pull in will be full is found as;

Zendaya has $700 to spend at a bicycle store for some new gear and biking outfits. assume all prices listed include tax. she buys a new bicycle for $242.33. she buys 3 bicycle reflectors for $7.17 each and a pair of bike gloves for $33.68. she plans to spend some or all of the money she has left to buy new biking outfits for $77.40 each. write and solve an inequality which can be used to determine xx, the number of outfits zendaya can purchase while staying within her budget.
Answer:
she could buy 5 outfits
Step-by-step explanation:
you multiply 7.17 by 3 = 21.51
700 - 21.51 = 678.49
678.49 - 242.33 = 436.16
436.16 - 33.68 = 402.48
402.48 divided by 77.40 = 5
