Answer:
1176 cm squared
Step-by-step explanation:
top: 1/2*6*16 = 3*16 = 48 cm squared
sides: 30*16 + 2(30*10) = 480 + 600 = 1,080 cm squared
bottom: same as top, so 48 cm squared
altogether: 48 + 1080 + 48 = 1080 + 96 = 1176 cm squared
hopefully this is correct
a post office always charges a flat one time fee for any order. one time, michael sent 35 letters and paid 26 dollars. the next time, he sent 18 letters and paid $14.10. how much does the post office charge to send one letter? what is the flat fee?
Answer:
$0.70 per letter, $1.50 flat fee
Step-by-step explanation:
x+18y=14.1 -> x=-18y+14.1
x+35y=26
|
\/
(-18y+14.1)+35y=26 -> 17y=11.9 -> y=0.7
|
\/
x+35(0.7)=26 -> x+24.5=26 -> x=1.5
|
\/
y=0.7
x=1.5
Hope this helps. :)
The post office charges $0.70 to send one letter, and there is a flat fee of $1.50.
How to determine the the flat fee (F) charged by the post officeTo find the cost of sending one letter, we need to determine the flat fee charged by the post office.
Let's denote the flat fee as 'F' and the cost per letter as 'C'.
From the given information, we can set up the following equations:
Equation 1: F + 35C = 26
Equation 2: F + 18C = 14.10
We can solve this system of equations to find the values of F and C.
First, we subtract Equation 2 from Equation 1 to eliminate F:
(F + 35C) - (F + 18C) = 26 - 14.10
17C = 11.90
Now, we divide both sides of the equation by 17 to solve for C:
C = 11.90 / 17
C ≈ 0.70
Therefore, the cost to send one letter (C) is approximately $0.70.
To find the flat fee (F), we can substitute the value of C into either Equation 1 or Equation 2. Let's use Equation 1:
F + 35(0.70) = 26
F + 24.50 = 26
F = 26 - 24.50
F = 1.50
Therefore, the flat fee (F) charged by the post office is $1.50.

This equation represents the scenario:
2a + 3p = 18
Choose the equations that are equivalent.
Check all that apply.
p = two-thirds a + 6
p = negative two-thirds a + 6
a = negative 1 and one-half p + 9
a = 1 and one-half p + 9
a = StartFraction negative 3 p + 18 Over 2 EndFraction
Answer:
p = -2/3a +6
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Step-by-step explanation:
2a + 3p = 18
Solve for a
2a +3p -3p = 18-3p
2a = 18 -3p
Divide by 2
a = 18/2 - 3p/2
a = 9 - 3/2 p
a = -3/2 p +9
a = -1 1/2 p +9
a = (-3p+18)/2
Solve for p
2a +3p = 18
3p = 18 -2a
Divide by 3
p = 18/3 - 2/3 a
p = 6 -2/3a
p = -2/3a +6
What is the magnitude (size) of -5.8?

What is an absolute function?The absolute function is also known as the mode function. The value of the absolute function is always positive.
The absolute function is given as
f(x) = | x – h | + k
The magnitude of the number will always be positive.
For example - The value of time, length, mass, temperature etc will always positive.
The magnitude of the negative 5.8 will be
⇒ |-5.8|
When the value in the mode may be negative or may be positive, but when the mode is removed, then the value becomes positive.
⇒ |-5.8|
⇒ 5.8
The magnitude of the negative 5.8 will be 5.8
Then the correct option is D.
