Plane A has heavier luggage with a total weight of 2,360 pounds.
Plane B has 2,320 pounds.
Because each dot represents 8 luggage cases, you can multiply the weight times the corresponding number of luggage. for example, there are 8 cases of luggage that weigh 28 pounds. In total, those 8 equal 224 pounds.

Question 1
Mr Brown has several models of famous people that each weigh the same. He decides to add in some new models that are of different weights to his old ones. In Room Number One, there are five old models along with a new model that weighs 240kg.
In Room Number Two, there are 3 old models along with a new model that weighs 510kg.
THE TOTAL WEIGHT OF THE MODELS IN ROOM ONE IS EXACTLY THE SAME AS THE TOTAL WEIGHT OF THE MODELS IN ROOM TWO.
What is the weight of an old model?
Answers
Answer:
135kg
Step-by-step explanation:
In room number one, there are five old models and a new model, which weights 240kg. So, it can be concluded that there are 6 models in there, and we can write it as 5x ( x = old models ) + 240 ( weight of new model ). then informed room number two, there are 3 old models and a new one, weighting 510kg. write it as 3x + 510.
the equation will be as: 5x + 240 = 3x + 510
move 3x to the front behind 5x, move +240 to the back behind 510. you will get 5x - 3x = 510 -240
which will be 2x = 270, then move 2 behind 270, means 270 divide 2, which then you will get 135kg

Jaya's coach agreed to buy ice cream for all of the team members. Ice cream cones are $2.40 each. Write and solve an equation to find how many cones the coach can buy with $30.
Let n represent the number of cones the coach can buy.
2.4 + n = 30 ; n = 27.6
n(2.4 + 4) = 30 ; n = 4.69
30 - 2.4 = n ; n = 27.6

what is lim x → -1 ln x
Answers
Answer:
Step-by-step explanation:
ln(∞) = ?
Since infinity is not a number, we should use limits:
x approaches infinity
The limit of the natural logarithm of x when x approaches infinity is infinity:
lim ln(x) = ∞
x→∞
x approaches minus infinity
The opposite case, the natural logarithm of minus infinity is undefined for real numbers, since the natural logarithm function is undefined for negative numbers:
lim ln(x) is undefined
x → -∞
So we can summarize
ln(∞) = ∞

b= where line intersects y axis
line 1: (-1,0), (0.5,1.5)

Pages is directly proportional to Minutes
P = KM
k = P/M
when P = 6, M = 12.
k = 6/12
k = 0.5
_____________________
when M = 1
P = Km
P = 0.5×1 = 0.5
P = half a page.
______________________
when M = 6
P = 0.5× 6
P = 3 pages

Answer: i think its 9 but sorry if I'm wrong I'm only in 4th grade
Step-by-step explanation:
In triangle ABC:
3^2+4^2= c^2
9+16=25
Square root of 25 is 5, so hypotenuse of triangle ABC is 5.
For triangle DEF, not that the given side is 8, which twice the amount of four. To find the other adjacent side of the triangle, we will multiply 3 by 2 because that is what we did with the 4. by doing this we can conclude that our other side is of the triangle is 6 Then, we have this pythagorean theorem to solve for FD:
8^2+6^2= C^2
64+36=100
C^2=100
The square root of the 100 is 10, therefore the length of side FD is 10.

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(1, 4) = 4. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 1 × 4 = 4. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - four minus one quarter = fifteen quarters.

Hii.
First, lets divide 1/9 by 5 .
1/9 divided by 5 is 1/45
Lets multiply to find out the answer.
1/9 x 5 =5/9.
So this is not correct since it does not equal 1/45
9/1 x 5/1 is 45
This is not correct because it does not equal 1/45
1/9 x 1/5 is 1/45
This is correct because it equals 1/45
