Given :
The Mad Hat Company must ship two different-sized boxes: The small ones cost them 45 cents each and weigh 6 ounces, and the large ones weigh 25 ounces and cost $1.20 each.
The total shipment this morning weighed 20 pounds 7 ounces and cost $18.45.
To Find :
How many packages of each size were shipped.
Solution :
We know, 1 pound = 16 ounces.
So, 20 pound = 20×16 = 320 ounces.
Let, number of large and small box are l and s.
So,
25l + 6s = 327 ...1)
0.45s + 1.20l = 18.45 ...2)
Solving both the equations, we get :
x = 9 and y = 17
Therefore, package smaller and big size are 17 and 9 respectively .
Hence, this is the required solution.

WILL GIVE BRAINLIEST write an equation for the nth term of the arithmetic sequence and find the 100th term 14,19,24,29, ...
Answer: the nth term of the sequence 14, 19, 24, 29 is: 5n+9 so the 100th term of the sequence will be 509.
explanation below:
Step-by-step explanation:
to find the 100th term we will have to find the nth term of the sequence when we have the nth term we need to replace n with the term we need to find and multiply it with the number behind n then subtract or add the number and u will get ur answer.
I hope this helps
Answer:
an=9+5n
a100=509
Step-by-step explanation:
a1=14
19-14=5
24-19=5
29-24=5
d=5
an=a1+(n-1)d
an=14+(n-1)(5)
an=14 +5n -5
an=9+5n
an=a1+(n-1)(d)
a100=14+(100-1)(5)
a100=14+(99)(5)
a100=14+495
a100=509
or
an=9+5n
a100=9+5(100)
a100=9+500
a100=509
A chain of retail computer stores opened 2 stores in its first year of operation. After 8 years of operation, the chain consisted of 206 stores. If the number of stores opening per year is increasing at an exponential rate, identify the continuous rate of growth. Round k to the nearest hundredth. *
Answer:
0.66
Step-by-step explanation:
The exponential growth equation is expressed as;
S(t) = S0e^kt
S(t) is the number of stores after t years
S0 is the initial number of stores
If a chain of retail computer stores opened 2 stores in its first year of operation then at t = 1, S(t) = 2. Substitute into the equation;
2 = S0e^k(1)
2 = S0e^k .... 1
Also if after 8 years of operation, the chain consisted of 206 stores, this means at t = 8, S(t) = 206. Substitute into the equation;
206 = S0e^k(1)
206 = S0e^8k .... 2
Next is to calculate the value of k
Divide equation 2 by 1;
[tex]\frac{206}{2} = \frac{S0e^{8k} }{S0e^k }\\103 = e^{7k}\\apply \ ln \ to \ both \ sides\\ln103 = lne^{7k}\\ln103 = 7k\\k = \frac{ln103}{7}\\k = \frac{4.6347}{7} \\k = 0.6621[/tex]
Hence the value of k to the nearest hundredth is 0.66

When a plumber is called, the cost of the service call is $50 for him to show up at your house, plus an additional $25 per hour.
What is the slope ?
y is the total cost of the service call and x is the number of hours the plumber is at your home
Answer:
The slope is 25
y=mx+b with m representing slope
y=25x+50
Step-by-step explanation:
Use the point-slope equation to identify the slope and the coordinates of a point
on the line y - 4 = {(x - 1).
The slope of the line is

Tyler thinks that the relationship between the ages of the children in Family B can be described with 2m – 2y = 10, where m is the age of the middle child and y the age of the youngest. Explain why Tyler is right.
Answer:
m - y = 5 is equivalent to 2m - 2y = 10
Step-by-step explanation:
Given
m = age of middle child
y = age of youngest child
[SEE ATTACHMENT FOR COMPLETE QUESTION]
Required
Explain why Tyler is correct
From the question, we understand that m is 5 greater than y
This can be represented as
m = 5 + y
To explain why Tyler is correct, we simply solve the above expression.
First, subtract y from both sides
m - y = 5
Multiply both sides by 2
2 * (m - y) = 2 * 5
2m - 2y = 10
This implies that m - y = 5 is equivalent to 2m - 2y = 10
And that means, Tyler conclusion is correct
Which ratios are equivalent? Check all that apply.

21:25 and 30:50
0 3:5 and 5:10
5:6 and 20:24
Please help me I’m in 6th grade
Answer:
9:15 and 18:30 are equivalent. Both ratios are multiplied by 2
5:6 and 20:24 are equivalent. Both ratios are multiplied by 4
Answer:
09:15 and 18:30 and 5:6 and 20:24
Step-by-step explanation:
9+9 = 18 and 15 + 15 = 30. Thats how you get 18:30. Next, 5x4 = 20 and 6x4 = 24. 20:24. Hope this helps you :)

Jonathan wants to the new baseball game for his game console. The game costs $45.99. Of sales tax is 6%, write an equation to find the total cost of the game, represented as P.
Answer: See explanation
Step-by-step explanation:
Cost of game = $45.99
Sales tax = 6%
The equation to find the total cost of the game, represented as P will be:
P = 45.99 + (6% × 45.99)
= 45.99 + (0.06 × 45.99)
= 45.99 + 2.7594
= $48.7494

Answer:
y=2x+4
Step-by-step explanation:
2 is the slope, you can see that with rise over run. 4 is the y intercept
Answer:
y=2x+4
Step-by-step explanation:
Look at the y-axis if the point that touches the y-axis is 4
Then the slope is 2
you go down 2 which is -2 (Since down is negative)
and you go left 1 which is -1 (Since left is negative)
now the equation looks like this:
y=-2/-1x+4
Simplify: (negative and negative cancel each other out making it positive)
y=2x+5
