point Find the length of segment CD with C(2,3) and D (-3, 15
Step-by-step explanation:
so, if the text is correct, the 2 points are
(2, 3) and (-3, 15).
the length of the line segment is the distance between both points.
did this we use Pythagoras for right-angled triangles.
c² = a² + b²
c is the Hypotenuse and the distance between both points. a and b are the legs (enclosing the 90 degree angle), which are simply the differences of the x and the y coordinates.
so,
distance² = (2 - -3)² + (3 - 15)² = 5² + (-12)² = 25 + 144 = 169
distance = sqrt(169) = 13 = length of line segment

Crab Weight
= 42 1/5 - 41/5
= 211/5 - 41/5
= 170/5
Combined weight
= 170/5 + 211/5

Find the area
For height of garden we can use Phytagoreaan Theorem :
h² = 25² - 7²
h² = 625 - 49
h² = 576
h = 16 m
Area
= 1/2 × base × height
= 1/2 × 14 m × 16 m
= 7 m × 16 m
= 112 m²

If -13(q+4) is equal to 7q+16 what’s is q
Answer:
q = - 3.4
Step-by-step explanation:
- 13(q + 4) = 7q + 16 ← distribute parenthesis on left side
- 13q - 52 = 7q + 16 ( subtract 7q from both sides )
- 20q - 52 = 16 ( add 52 to both sides )
- 20q = 68 ( divide both sides by - 20 )
q = - 3.4

This question is really bothering me: A restaurant has a square floor with an area of 324 m². Sketch the restaurant floor. dimensions are to be evaluated.
Surface area is defined as the collective region, whose mathematical expression can be formed.
here,
Let the sides of the square restaurant be a,
The area of the restaurant = area of the square
324 = a²
a = √324
a = 18 meters,

How many different 9-letter "words" can you
make by arranging the letters in DEVIATION?
The arrangements don't have to be actual words
that are included in any dictionary.
There are 5040 different 9-letter “words” that can be made by arranging the letters in DEVIATION.
The given word is DEVIATION and we are required to find out the number of different 9-letter “words” that can be formed by arranging its letters.
To solve the problem, we will use the formula for finding permutations of n objects taken r at a time when all the objects are distinct.
The formula is given by: nPr = n! / (n-r)! where n is the total number of objects and r is the number of objects to be selected.
Here, we have 9 objects (letters) and we need to arrange all of them, so r = 9.
Now, we need to find out the value of n.
The given word DEVIATION has 9 letters, but two of them (E and I) are repeated twice.
Therefore, n = 9 - 2 = 7.
We will substitute these values in the formula to get the required answer:
nPr = n! / (n-r)! = 7! / (7-9)! = 7! / (-2)! = 7! / 1 = 5040
Therefore, there are 5040 different 9-letter “words” that can be made by arranging the letters in DEVIATION.

Hi can u plz help me
Answer:
7 / 6
Step-by-step explanation:
( 2x + 6 ) / 5 = 4x - 3
2x + 6 = 5 ( 4x - 3 )
2x + 6 = 20x - 15
20x - 15 = 2x + 6
20x - 2x = 6 + 15
18x = 21
x = 21 / 18
21 = 7 * 3
18 = 6 * 3
x = 21 / 18
= ( 7 * 3 ) / ( 6 * 3 )
x = 7 / 6
Hence proved.

A company that teaches self-improvement seminars is holding one of its seminars in
Hampton. The company pays a flat fee of $69 to rent a facility in which to hold each session.
Additionally, for every attendee who registers, the company must spend $15 to purchase
books and supplies. Each attendee will pay $18 for the seminar. Once a certain number of
attendee register, the company will be breaking even. How many attendees will that take?
What will be the company's total expenses and revenues?
Step-by-step explanation:
I take it that the $69 flat fee is for one event.
and we are talking about one event overall.
"breaking even" means that the sum of all expenses and revenues is 0.
so, with x being the number of attendees,
0 = 18x - 15x - 69
69 = 3x
x = 23
that means, with 23 attendees they will break even, and with every attendee more they will gain.
in the case of 23 attendees the company will have expenses of 69 + 23×15 = $414.
and the revenues are 23×18 = $414

Problem 2: A ball is dropped from rest from a height of 6 meters, Find the time it takes the ball
to fall. Find the velocity of the ball just before it hits the earth. Assume no air resistance and
that acceleration due to gravity (g) is 9.8 m/s/s.
Answer:
1.11 s , 10.88 m/s
Step-by-step explanation:
Initial velocity and air resistance = 0
Time to fall : s = 1/2 gt²
6 = 1/2 * 9.8 * t²
t² = 1.224
t = 1.11 s
final velocity = initial velocity + gt
= 0 + 9.8 * 1.11
= 10.88 m/s

At a super market broccoli and celery are sold at $0.59 per 100 g and $0.26 pee 100g.how much do 1.2 kg of broccoli and 950 g of celery costs
1.2 kg of broccoli costs $7.08.
950 g of celery costs $2.47.
In order to determine the cost of 1.2 kg of broccoli, the first step is to determine the cost of 1kg of broccoli
1 kg = 1000 g
100g = 0.1 kg
Cost of one kg of broccoli = $0.59 / 0.1 = $5.90
The second step is to determine the cost of 1.2kg of broccoli.
$5.9 x 1.2 = $7.08
In order to determine the cost of 950g of celery, the cost of 1g of celery.
$0.26 / 100 = $0.0026
The second step is to determine the cost of 950g of celery.
950 x 0.0026 = $2.47

1) Hot dogs are sold in packs of 10 and hot dog buns are sold in packs of 8. Tommy wants
to know the least number of packs of hot dogs and buns he needs to buy so that he does not
have any left over.
) Complete the table.
Answer:
10, 20,30, 40, 50
Step-by-step explanation:
You times them all by 10 for example: 1x10=10 2x10=20 3x10= 30 4x10=40 and 5x10=50.
If we buy four packs of hot dogs and five packs of buns then we don't have any left over.
What is Least common multiple?The abbreviation LCM stands for "Least Common Multiple." The smallest multiple that two or more numbers share is known as the least common multiple.
For example: Take two integers, 2 and 3.
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20….
Multiples of 3: 3, 6, 9, 12, 15, 18, 21, 24, 27, 30 ….
Therefore, 6 is the least common multiple of 2 and 3.
Given:
Packs 1 2 3 4 5
Hot Dogs 10 20 30 40 50
Bun 8 16 24 32 40
Also, LCM(10, 8)
10= 2 x 5
8= 2 x 2 x 2
So, LCM(10, 8)= 2 x 2 x 2 x 5 = 40
Hence, If we buy four packs of hot dogs and five packs of buns then we don't have any left over.
