Answer:
[tex]\$1.75[/tex]
Step-by-step explanation:
Total amount paid for the nuts is $19.60
Total amount paid for the ribbons is $11.20
Profit made on each jar is 98￠= $0.98
Cost price of the nuts and ribbon for the 40 jars is [tex]19.6+11.2=\$30.8[/tex]
Cost price for nuts and ribbonn for one jar = [tex]\dfrac{30.8}{40}=\$0.77[/tex]
Selling price is the sum of the cost price and profit.
Selling price for one jar = [tex]0.77+0.98=\$1.75[/tex]
They charged [tex]\$1.75[/tex] for each jar.
Ellie took a taxi from her house to the airport. The taxi company charged a pick-up fee of $1.50 plus $5 per mile. The total fare was $76,50, not including the tip. Write and solve an equation which can be used to determine m, the number of miles in the taxi ride.
I dont understand this
Answer: 1.50+5m=76.50 m=15
Step-by-step explanation:
The required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now it is given that,
pick-up fee = $1.50 plus $5 per mile
Since, m is the number of miles in the taxi ride
So, equation for pick-up fee for m miles,
pick-up fee = $1.50 + $5m
Now total fare = $76,50
Thus, required equation to determine m is given as,
1.50 + 5m = 76.50
Subtracting 1.5 both the side we get,
1.50 + 5m - 1.5 = 76.50 - 1.5
⇒ 5m = 75
or, m = 75/5
⇒ m = 15
Thus, the required equation is 1.5 + 5m = 76.50 and distance travelled is 15 miles.

Item 3
The table shows the cost of renting bowling shoes.
Number of Pairs of Shoes Cost
1 $2.50
2 $5.00
3 $7.50
4 $10.00
5 $12.50
What does the rate of change mean in this situation?
The cost increases $10.00 for every additional pair of shoes rented.
The cost increases $5.00 for every additional pair of shoes rented.
The cost increases $2.50 for every additional pair of shoes rented.
The cost increases $7.50 for every additional pair of shoes rented.
Answer:
C) The cost increases $2.50 for every additional pair of shoes rented.
Step-by-step explanation:
Notice a pattern. When you buy a new pair of shoes, the total gets increased by $2.50 depending on how many pairs of shoes you buy. For example, starting with 1 pair of shoes, it costs $2.50, but when you buy another pair, the cost is $2.50+$2.50=2*$2.50=$5.00, and so on...
Therefore, the correct choice is C

What is the length of side AC
Answer:
7 Units.
Step-by-step explanation:
First of all, you could just count the units, but that's not really too effective. Otherwise, you could start from the coordinates of the "C" point, and see how it's at -Y = -5. Therefore, to get to the line separating the two points, you would have to subtract 5 from 5 to get to the line. Now, you look at point "A". It's Y coordinate is 2. Therefore, adding 5 and 2 together gives you 7 units.

Rearrange
12y + y (-y) + 15 (-15) - 36y - 9 (+9)= y (-y) (-15) (+9)
12y - 36y = - 15 + 9
-24y = - 6

Answer:
i believe x is 12.
Step-by-step explanation:
three times three is nine, so you multiply four by three to get 12. you can also check your answer by dividing 12 by three and 9 by three to get 4,3 so the answer is correct.
Answer:
x=12
Step-by-step explanation:
How I solved this is by making a proportion with fractions In your first fraction the numerator is 4 and your denominator is 3. In your second fraction your numerator is x and your denominator is 9. You would multiply 4 times 9 then divide by 3 to get your answer. I hope this is correct and good luck!!

[tex]\huge\boxed{\sf x = 20}[/tex]
Step-by-step explanation:
=> Since it is an equilateral (Having all angles and all sides equal) triangle, so every angles will be equal to the other.
=> The sum of the measures of interior angles of triangle add up to 180 degrees.
So,
3x + 3x + 3x = 180
9x = 180
Divide both sides by 9
x = 20

Hello! :)
[tex]\large\boxed{\frac{-e^{\frac{3}{x}} (3 + 2x )}{x^{4}}}[/tex]
Find the derivative using the quotient rule:
[tex]\frac{f(x)}{g(x)} = \frac{g(x) * f'(x) - f(x) * g'(x)}{(g(x))^{2}}[/tex]
In this instance:
[tex]f(x) = e^{\frac{3}{x} }\\\\g(x) = x^{2}[/tex]
Use the following properties to find the derivative of f(x) and g(x):

Use the quotient rule:
[tex]\frac{x^{2} * (e^{\frac{3}{x}} * (-3x^{-2})) - e^{\frac{3}{x}} * 2x }{(x^{2} )^{2}}[/tex]
Simplify the numerator:
