Answer: 33
Step-by-step explanation:
From the question, a trial of 10 filters shows the effective days of each filter to be 94, 101, 120, 87, 93, 91, 105, 92, 91, and 100.
The range of effective days of the trial water filters will be the difference between the highest number given and the smallest number given.
Highest number = 120
Lowest number = 87
Range = 120 - 87 = 33
VGeorge has $15. He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money. Look at the numerical expression George used: 15 − 9 + 2.65 + 1.35 + 2(1.74) Can you help him determine why he does not have enough money?
Given:
George has $15.
He tries to buy a movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) but he does not have enough money.
George used: 15 − 9 + 2.65 + 1.35 + 2(1.74)
To find:
Why he does not have enough money.
Solution:
Money her has = $15
All the expenses movie ticket ($9.00), a pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each) must be subtracted from the money he has instead of adding these values.
George add the cost of pretzel ($2.65), a drink ($1.35), and two veggie cups ($1.74 each), therefore, he does not have enough money.
Remaining Amount = [tex]15-9-2.65-1.35-2(1.74)[/tex]
[tex]=15-9-2.65-1.35-3.48[/tex]
[tex]=15-16.48[/tex]
[tex]=-1.48[/tex]
Remaining money cannot be negative. Here expenses are more than the money he has. Therefore, he does not have enough money.
Answer:
it's not the best answer but i hope it helps
Step-by-step explanation:
George only has $15 dollars left. He spend $9.00 on a movie ticket and $2.65 on a pretzel. $9.00 - $2.65 would leave him with $6.35. Then, George decided to buy a drink for $1.35. George then wanted to get two veggie cups both for the price of $1.74, but if you subtract $1.35 - $1.74 thus would leave him with $0.39 and he wouldn't have enough money to buy both veggie cups. If George had $1.38 left then he would have enough to buy both veggie cups.
Write the equation of the line that passes through the given point and is perpendicular to the given line. (0, 3); 3x − 4y = −8
Answer:
y = -4/3x + 3
Step-by-step explanation:
3x − 4y = −8
-4y = -3x - 8
y = 3/4x + 2
slope m = 3/4
perpendicular version of it is opposite inverse: -4/3
y-intercept through point (0, 3):
y = mx + b
3 = -4/3(0) + b
b = 3
Use the perpendicular slope with b from above to form new perpendicular equation of line:
y = mx + b
y = -4/3x + 3
i need help with 2: simplify algebraic expressions
Answer:
a). 11x²
b). 6x + 5y
c). -4x - 20
Step-by-step explanation:
a). 8x² + 3x²
When you collect the like terms (8 and 3 are the coefficients of x²) and add them together, you get 11x²
b). 3x - 5x + y + 4y + 8x
Start by placing the like terms next to each other.
3x - 5x + 8x + y + 4y
Then add/subtract
6x + 5y
c). -4(x + 7) + 8
First, you have to expand the expression and then simplify.
-4x - 28 + 8
-4x - 20

Write the equation of the line, with the given properties, in slope-intercept form.
Slope = -4, through (7,4)
Answer:
Step-by-step explanation:
Slope-intercept form means the equation should be written in this manner
[tex]y=mx+c[/tex]
where m is the slope and c is the y-intercept
so lets take all the date we have to achieve it.
We have a point (7,4) and slope which is m= -4 we can substitute the slope and point in our equation and find the y-intercept .
[tex]y=mx+c\\4=(-4)(7)+c\\4=-28+c\\32=c[/tex]
so now we have our y-intercept that is c=32
now for the equation to be in the slope-intercept form we need m and c and we have both so just replace these variables with their values.
[tex]y=-4x+32[/tex]

-17(y-2) = -17y + 64
Answer:
No solution.
Step-by-step explanation:
Step 1: Write equation
-17(y - 2) = -17y + 64
Step 2: Solve for y
Distribute -17: -17y + 34 = -17y + 64Add 17y on both sides: 34 ≠ 64Here we see that we get y = no solution. You could also think about it as 2 parallel lines; they have the same slope but different y-intercepts so therefore there will be no intersection/no solution.

The table shows the price for different numbers of chocolate boxes:
Number of Chocolate Boxes Price (in dollars)
2 10
3 15
4 20
5 25
Does this table of numbers represent a proportional relationship? (1 point)
No, because the price of 3 boxes should be $11
No, because the price of 4 boxes should be $40
Yes, because 5 times the price is the number of boxes
Yes, because the price is 5 times the number of boxes

Triangle ABC is translated 2 units up and 4 units to the right and is then rotated 180° to
produce the image triangle A'B'C'. What are the coordinates of B' in the resulting figure?
Answer:
[tex]B' = (7,-6)[/tex]
Step-by-step explanation:
From the attachment, we have that:
[tex]A = (1,8)[/tex]
[tex]B = (-3,4)[/tex]
[tex]C = (4,-2)[/tex]
Required
Determine B'
Taking the translation one at a time:
2 units up
This implies, we add 2 to the y value of the function
[tex]B = (-3,4)[/tex] becomes
[tex]B' = (-3, 4 + 2)[/tex]
[tex]B' = (-3, 6)[/tex]
4 units right
This implies, we subtract 4 to the x value of the function
[tex]B' = (-3, 6)[/tex] becomes
[tex]B' = (-3 - 4,6)[/tex]
[tex]B' = (-7,6)[/tex]
180 degrees rotation
Here; B'(x,y) becomes B'(-x,-y)
So, the initial coordinates [tex]B' = (-7,6)[/tex]
becomes
[tex]B' = (-(-7),-6)[/tex]
[tex]B' = (7,-6)[/tex]
Hence:
The final coordinates of B' is [tex]B' = (7,-6)[/tex]

a(b+c) - d = e, for a
Answer:
a = [tex]\frac{e+d}{b+c}[/tex]
Step-by-step explanation:
To isolate the a, the first thing I would do is bring the d to the other side of the equation, remember to switch the sign. This would give me a(b+c) = e+d. Next, in order to get rid of the (b+c), bring it to the other side by dividing since it is attached to the a variable by multiplication. This leaves me with a = e+d / b+c. Make sure not to distribute, this would duplicate your a variable.

Given the equation: 3x-4y=24
Find two solutions to the equation
Write your answers as coordinates
Answer:
Step-by-step explanation:
we can write this equation into a function to easily plug in values and find solutions
[tex]3x - 4y = 24\\4y = 3x - 24\\y = \frac{3x}{4} - 6[/tex]
now we can plug in any x value and find an appropriate y value
e.g.
x = 0, y = -6 (0, -6)
x = 4, y = -3 (4, -3) [tex]\frac{3(4)}{4} - 6 = 3 - 6 = -3[/tex]
x = 16, y = 6 (16, 6) [tex]\frac{3*16}{4} - 6 = 12 - 6 = 6[/tex]

Answer:
1 - a. addition
2 - c. constant
3. - b. coefficient
4. - d variable
Step-by-step explanation:
+ is the universal sign for addition
11 is a number which is always constant
here w doesn't have a constant value and can be any number. hence it is a variable
the 2 in the 2w is a number which multiplies with the variable w. the value of 2w varies with the value of w. So here 2 is the coefficient of the w in 2w
