Eric will run at least 35 miles this week. So far, he has run 18 miles. What are the possible numbers of additional miles he will run?
Use t for the number of additional miles he will run.
Write your answer as an inequality solved for t.
Answer:
18 + t ≥ 35
possibly 17 miles or more
Step-by-step explanation:
18 + t = 35 --> minus 18 on both sides
t = 17
18 + t ≥ 35

2 x 2 = boys
There are 4 boys
But they are asking total children which will include the girls,
4 + 2 = 6 children

the coeffient of variation, expressed as a percent, is used to describe the standard deviation relative to the mean. It allows us to compare variability of data sets with different measurement units and is calculated as coefficient of variation =100(s/x) Find the coefficient of variation for the following sample weights in pounds 130,127,186,105,197,153,172,150,116,125
The required coefficient of variation 23.44.
What is sample space?
A sample space is a set of potential results from a random experiment. The letter "S" is used to denote the sample space.
Given that,
The coefficient of variation for the sample,
CV = 100(s/x),
Where s is the standard deviation and x is the mean,
According to the provided formula,
The mean weight is 143.5 pounds,
And the standard deviation is 33.65 pounds.
Thus, after entering those values:
CV = 100 * (33.65/143.5)
CV ≈ 23.44
Therefore, for the sample weights in pounds that is given, the coefficient of variation is roughly 23.44.

7 inches high, 4 inches long, and 4 inches wide what is the area
A = 144 square inches
Step-by-step explanation:
surface area of rectangular prism :
A = 2(hℓ + ℓw + hw)
A = 2(7 · 4 + 4 · 4 + 7 · 4)
A = 2(28 + 16 + 28)
A = 2(72)

y= 5x - 7
-3x - 2y = -12
Slove step by step
Answer:
(2,3)
Step-by-step explanation:
- Substitute the equation for y instead of the y variable.
-3x - 2(5x - 7) = -12
-3x - 10x + 14 = -12
-13x = -26
x = 2
- Now substitute the value of x into the other equation.
y = 5x - 7
y = 5(2) - 7
y = 10 - 7
y = 3
Answer:
x = 2 and y = 3
Step-by-step explanation:
y = 5x - 7
-3x - 2y = -12
Substitute y into the second equation:
-3x - 2(5x-7) = -12
Simplify:
-13x = -26
x = 2
Substitute x into the first equation:
y = 5(2) - 7
y = 10 - 7
y = 3

Need help on order of operations
Answer: p.e.m.d.a.s
Step-by-step explanation: parenthese, exponent, multiplication, division, addition, subtraction
Answer:
You can follow the P.E.M.D.A.S.
Step-by-step explanation:
If you need an explanation for this, the P.E.M.D.A.S are a way to remember the Order of Operations. We can explain this with a simple equation, such as:
4/2+(3*2)-2^2
To begin with, we need to start with the Parentheses. Three times two is equal to six, so now the equation looks like this:
4/2+6-2^2
After that, you need to move onto the Exponents. Two to the power of two (marked with the ^) is four, so we replace 2^2 with a 4.
4/2+6-4
Next, we do the Multiplication and the Division. Since there's no multiplication involved with this particular problem, we'll go right onto the division. 4/2 is equal to two, so you replace that with a simple 2.
2+6-4
Now, lastly you wrap up by doing the Addition and the Subtraction. 2+6-4 is equal to 8-4, and the answer is ultimately 4. A reminder is that you always need to go left to right no matter what or else your solution will most likely be wrong.
I hope this helps! Marking as Brainliest would be highly appreciated. Have a wonderful day. :)

What is the product of power rule
Answer:
677
Step-by-step explanation:
A store received 620 containers of milk to be sold by March 1. Each container cost
the store $0.78 and sold for $1.56. The store signed a contract with the distributor in
which the distributor agreed to a $0.40 refund for every container not sold by March
1. If 430 containers were sold by March 1, how much profit did the store make?
9514 1404 393
Answer:
$263.20
Step-by-step explanation:
The number not sold was ...
620 -430 = 190
The cost for a container not sold was ...
$0.78 -0.40 = $0.38
__
The cost of containers sold was ...
$0.78 × 430 = $335.40
The cost of containers not sold was ...
$0.38 × 190 = $72.20
The total cost for the 620 containers of milk was ...
$335.40 +72.20 = $407.60
The total revenue from the 430 containers sold was ...
$1.56 × 430 = $670.80
Then the profit was ...
profit = revenue - cost
profit = $670.80 -407.60 = $263.20
_____
Additional comment
The calculation can be simplified to ...
$1.16 × (number sold) - $0.38 × (number bought)

Mary borrowed $4,500 to help
pay for college. If the bank
charges a 5.5% annual interest
rate, how much interest will
Mary pay after 4 1/2 years?
Answer:
1113.75
Step-by-step explanation:
The formula for simple interest is as follows: Simple interest = principal balance x interest rate x term of the loan
P=4500
i= 0.055
t=4.5
multiplying them together we get
1113.75
The reason that this is simple interest is because compound interest increases over time as an exponential
