4 tons of mulch cost $28,080.00 what is the price per pounds
Step-by-step explanation:
in the strange US system there is suddenly a metric relationship :
1 ton = 2000 pounds.
FYI - an actual (metric) ton is 1000 kg, which is
2,204.6226218488 pounds.
anyway, as 1 ton = 2000 pounds, then 4 tons = 4×2000 = 8000 pounds.
8000 pounds cost $28,080.00.
1 pound costs therefore
28080/8000 = $3.51

On average the number of drum sets sold in Michigan each year is 101,968, which is eight times the average number of drum sets sold each year in South Dakota. How many drum sets, on average, are sold each year in South Dakota?
Answer:
12,746
Step-by-step explanation:
To find this answer, we need to divide by 8
Since we know that South Dakota sells 8X less than Michigan, we have to use the opposite sign (which in this case is division.)
Now, we use the equation 101,968/8 which gets us an answer of…
12,746!
Nicole has a machine that will produce a number from 1 through 50 when she pushes a button. If she pushes the button, what is the probability of:
a. P(multiple of 10)
b. P(not 100)
C. P (not a multiple of 4)
d. P (one-digit number)?
Answer: Number from 1 through 50. 50 possible numbers. multiple of 10 : 10, 20, 30, 40, 50. 5 possible events. multiple of 4: 4, 8, 12, 16, 20, 24, 28, 32, 36, 40, 44, 48. 12 possible events one-digit number: 1, 2, 3, 4, 5, 6, 7, 8, 9. 9 possible events P(multiple of 10) = 5/50 or 1/10 P(not 100) = 50/50 or 1 P(not a multiple of 4) = 38/50 or 19/25 P(one-digit number) = 9/50
Answer: See below
Step-by-step explanation:
Test 1:
5 numbers that are a multiple of 10
Total amount of numbers = 50
Probability = 10/50
P = 1/5 or 20%
Test 2:
None of the numbers from 1 to 50 are 100, so obviously the probability will be 1 or 100%
Test 3:
12 multiples of 4 in all 50 numbers, since we want numbers that are not multiples of 4 we subtract the total number of them from 50
50 - 12 = 38
Probability = 38/50
P = 19/25 or 76%
Test 4:
There are 9 one-digit numbers in total
Probability = 9/50
P = 9/50 or 18%

The cat weighs 7 3/4 pounds.The cats weight is 2/3 the weight of the dog.How much does the dog weigh!
Answer:
11.625 pounds
Step-by-step explanation:
x = weight of dog
7 3/4 = 2/3(x)
7 3/4 divided by 2/3 = x
x = 11.625 pounds
Answer:
11 5/8
Step-by-step explanation:
let 'd' = dogs weight
7 3/4 equals 2/3d
change 7 3/4 to an improper fraction: 31/4
to isolate 'd', each side needs to be multiplied by 3/2
31/4 × 3/2 = d
93/8 = d
11 5/8 equals dogs weight

The variable expression for "twenty-nine more than one-third of the square of z" is (1/3) × z² + 29.
Given information:
29 greater than one-third of the square of z
Let's break down the sentence into parts to create a variable expression as follows:
The square of z as show below:
z²
One-third of the square of z given as:
(1/3) × z²
Twenty-nine more than one-third of the square of z as given below:
(1/3) × z² + 29

A railroad track rises 10 feet for every 400
feet along the track. What is the measure-
ment of the angle the track forms with the
horizontal?
Answer:
1.43 degrees
Step-by-step explanation:
Think of this as a triangle with an x (horizontal) value of 400 and a y (vertical) value of 10.
Using this train of thought, we can use SOHCAHTOA to find that the tan of some angle (we will use Ф to represent this angle) is equal to the opposite (vertical) value divided by the adjacent (horizontal) value.
As an equation, it looks like this: tan (Ф) = 10/400.
We can use the arctan to find Ф from this equation: arctan (10/400) = Ф
Therefore, Ф is about 1.43 degrees.
