Answer:
About 969 dollars
Step-by-step explanation:
I kind of did it the long way. I divided $1,404 by 100 and multiplied by 19. Did the same thing with 12. Added the product of those together and subtracted from 1,404.
(1,404÷100)19 + (1,404÷100)12 = 435.24
1,404 - 435.24 = 968.76
Since it was an estimate I rounded it to the nearest whole number and got 969
Hope this helps. There are probably better methods to solve this problem but this was my way.

what property is illustrated by the statement 3+z=z+3???
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
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

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;
[tex]\rm P= \frac{Favourable}{Total \ outcomes } \\\\\ P(full)= \frac{16}{16+4} \\\\\ P(full)=\frac{16}{20} \\\\ P(full)= \frac{4}{5}[/tex]
Hence, the experimental probability that the next train to pull in will be full is [tex]\rm \frac{4}{5}[/tex].

[?] edges
The number of edges of a polyhedron with 4 faces and 4 vertices will be 6.
What is a polygon?The polygon is a 2D geometry that has a finite number of sides. And all the sides of the polygon are straight lines connected to each other side by side.
Using Euler's formula, the number of the edges does a polyhedron with 4 faces and 4 vertices have
We know the formula for the edges of the polyhedron will be
F + V = E + 2
The number of faces, vertices, and edges of a polyhedron are denoted by the letters F, V, and E.
Then we have
4 + 4 = E + 2
E = 8 - 2

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.

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.

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

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

Two cheeseburgers and one small order of fries contain a total of 1320 calories. Three cheeseburgers and two small orders of fries contain a total of 2170 calories. Find the caloric
content of each item.
Answer:
cheeseburger: 470 caloriesfries: 380 caloriesStep-by-step explanation:
The given relations let you formulate two equations in the two unknown values. These can be solved by any of the usual methods.
__
setupLet x represent the caloric content of a cheeseburger, and y the caloric content of a small order of fries. The problem statement tells us ...
2x +y = 1320
3x +2y = 2170
__
solutionSubtracting the second equation from twice the first gives ...
2(2x +y) -(3x +2y) = 2(1320) -(2170)
x = 470
Using the first equation, we can find y:
y = 1320 -2x = 1320 -2(470) = 380
__
A cheeseburger has 470 calories; a small order of fries, 380 calories.

-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

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.
Please Help Me !! ITS A MATH PROBLEM
Answer:
Step-by-step explanation:
Remark
You are trying to convert the base function f(x) = x^2 into the child function g(x) = -(x + 3)^2 + 5
UP
Start with the simplest part of the transformations. + 5
If you have g(x) = f(x)+5 what you have done is move the function up 5 units on your grid.
Up side Down
Next is the - sign.
f(x) = x^2
g(x) = - f(x) = - x^2
This has the affect of turning x^2 upside down. It looks like a cup opening towards the counter or down.
Left right
The last step is left / right. This is the hard one. It moves in the opposite direction that you think it should. x +3 moves the parabola left, not right. If you want it to move right, use (x - 3)
Graph
I have enclosed a graph to show you exactly what is going on. The red line is f(x)=x^2
