it will take 5 months for Bill to weigh the same as Phil.
Let's represent the number of months they gain extra weight as: m
Step 1
Bill weighs 120 lbs and is gaining ten lbs each month. The algebraic equation for the above statement is :
120 ib + 10 ib x m
120 + 10m ........Equation 1
Phil weighs 150 lbs and is gaining four lbs each month. The algebraic equation for the above statement is :
150 ib + 4 ib x m
150 + 4m ........Equation 2
Step 2
We equate equations 1 and 2 to each other
Equation 1 = Equation 2
120 + 10m = 150 + 4m
Collect like terms
10m - 4m = 150 - 120
6m = 30
Divide both sides by 6
6m/6 = 30/6
m = 5
Therefore, it will take 5 months for Bill to weigh the same as Phil

The prefix milli- means one thousandth, or 10–3. how many milliseconds (ms) are in 6.7 seconds? 6.7 × 10–3 ms 2.0 × 104 ms 6.7 × 102 ms 6.7 × 103 ms
You know that the prefix mili means one thousandth or 1/100.
Numerically speaking, one thousandth is equals to 10 to the power of negative 3.
Solving seconds to milliseconds:
6.7 seconds x 1000 milliseconds / 1 second
Cancelling out the unit seconds. Then multiplying 6.7 to 1000 milliseconds.
The answer is 6,700 milliseconds or 6.7 x 10^3 ms

Answer:
1: option:D
2: option:D
Step-by-step explanation:
1:
Clearly as we see the time of sasha practice it increases by a fixed factor of '2'. but when we see the time of mona's practice it increases by 10mins every week. hence there is a addition of a fixed number '10'.
so option D is correct;which says Sasha's methid is exponential because it increases by a fixed factor, and mona's method is linear because it increases by a fixed number.
2:
option D determines that the rate are increasing exponentially.

Which type of question fits a binomial model? A. fill in the blank B. matching C. multiple choice D. true/false
The type of question that fits a binomial model is a true/false question, as this type of question strictly limits the outcome to two possibilities - correct or incorrect.
Explanation:The type of question that fits into a binomial model would be a true/false question. A binomial distribution, in mathematics and statistics, is used to model a number of successes in a sequence of independent and identically distributed binary experiments, such as flipping a coin or indeed, answering a true/false question. These types of questions are considered binomial because there are two possible outcomes: right or wrong, true or false. On the other hand, options like 'fill in the blank', 'matching', or 'multiple choice' doesn't fit the binomial model because they do not strictly limit the outcome to two possibilities.

Name the set(s) of numbers to which 1.18 belongs.
a. rational numbers
b. rational numbers, irrational numbers
c. natural numbers, whole numbers, integers, rational numbers
Answer:
a. rational numbers
Step-by-step explanation:
The number is between integers, so it can't be an integer or a whole number.
In general, 1.18 belongs to three sets of numbers.
Firstly, it is a rational number because it can be written in the form p/q where p and q are integers and q is not equal to zero.
1.18=[tex]\frac{118}{100}[/tex]
Secondly, all rational numbers are also real numbers and all real numbers are complex numbers.
But we have been given to choose from only rational numbers, irrational numbers, natural numbers or whole numbers.
So, the only answer is rational number.

Rename 12,000 ten thousand
Renaming 12,000 as 'ten thousand' means expressing it as '1 ten thousand and 2 thousand'. This breaks the number down into units of ten thousand, with 10,000 being the base unit and the additional 2,000 making up the rest.
Explanation:The phrase 'rename 12,000 ten thousand' refers to the process of expressing the number 12,000 in terms of ten thousand. To do this, we need to understand that the number 10,000 is a base unit in this context, acting as one 'ten thousand'. Therefore, the number 12,000 would be considered as 1 ten thousand and 2 thousand, since 12,000 is made up of one 10,000 and an additional 2,000 units.
To better understand, let's do a breakdown:
10,000 (one ten thousand) + 2,000 (two thousand) = 12,000We know that:
10,000 is one ten thousand.20,000 is two ten thousands.30,000 is three ten thousands.And so on, up to 160,000, which would be sixteen ten thousands.In this case, when we want to 'rename' 12,000 as ten thousand, it becomes 1 ten thousand and 2 thousand.

What is y=-4x-15 in standard form
Final answer:
To convert the equation y = -4x - 15 to standard form, you add 4x to both sides to get 4x + y = -15, which aligns with the standard form Ax + By = C.
Explanation:
To convert the equation y = -4x - 15 into standard form, we need to rearrange it such that the x- and y-terms are on one side of the equation and the constant is on the other side, typically with the x term first. The standard form of a linear equation is Ax + By = C, where A, B, and C are integers, and A should be non-negative.
The given equation is already close to this form, but we need to get the x-term to the other side of the equation. To do this, we simply add 4x to both sides, giving us:
4x + y = -15
This is the standard form of the given linear equation.

To burn 1 molecule of c7h16 to form co2 and h2o (complete combustion), how many molecules of o2 are required?
Eleven molecules of O2 are required to completely combust one molecule of C7H16, producing CO2 and H2O. The balanced chemical reaction of this process is: C7H16 + 11O2 → 7CO2 + 8H2O.
Explanation:Combustion of one molecule of C7H16 (heptane) to produce CO2 (carbon dioxide) and H2O (water) requires 11 molecules of O2 (oxygen). The balanced chemical equation of this reaction is:
C7H16 + 11O2 → 7CO2 + 8H2O
The equation shows that for every one molecule (or mole) of C7H16, 11 molecules (or 11 moles) of oxygen are needed. An analogy can be seen in the combustion of methane where one methane molecule and two oxygen molecules react to yield one carbon dioxide molecule and two water molecules.

If you are passing a large tractor trailer rig going 50 mph, how long will it take to pass if you use the correct passing techniques?
To pass a truck going 55 mph while you go 60 mph, it will take about 8.94 seconds if using the correct passing techniques. This calculation is based on the relative speed and the total distance required to pass the truck.
First, consider the difference in speeds between the car and the truck. Assuming the truck is going 55 mph as stated in the reference information, and the car speeds up to 60 mph:
Calculate the relative speed:Therefore, it will take approximately 8.94 seconds to pass the truck completely.

Find the equation of the line perpendicular to x−5y=15 that passes through the point (−2,5).
1. Solve the given equation for y.
x - 5y = 15
-5y = -x + 15
y = (-x + 15)/-5
y = (x/5) - 3
y = (1/5)(x) - 3
The slope is 1/5. See it?
The equation we are looking for has a slope which is the negative inverse of the slope in the equation we just solved for y.
The slope for the equation we want is -5 which is the negative inverse of 1/5. Undetstand?
We have the slope of the new equation and one point is given.
Plot BOTH into the point-slope formula and solve for y. To solve for a variable means to isolate the variable ALONE on one side of the equation.
y - y_1 = m(x - x_1)...This is the point-slope formula. Our given point is (5,-2)
y - 5 = -5(x - (-2))
y - 5 = -5(x + 2)
We now solve for y and that's it.
y - 5 = -5x - 10
y = -5x - 10 + 5
The equation we want is y = -5x - 5.

Final answer:
A combination of numbers, variables, and at least one operation is called an expression. It involves the use of variables and operators to represent mathematical relationships or operations. Expressions are fundamental in algebra for solving problems and describing mathematical properties.
Explanation:
A combination of numbers, variables, and at least one operation is called an expression. An expression is a mathematical statement that combines values, variables (which are symbols that represent unspecified numbers), and operators (special symbols that represent computations like addition, subtraction, multiplication, and division) to describe a sequence of operations that yield a single result. For example, the expression 5 - 3xy combines the numbers 5 and 3, the variable y, and the operations of subtraction and multiplication to form a single mathematical statement.

The Greenville Art Museum had 12 sculptures on display that were made by students. The museum received 3 more student sculptures. After two weeks they loaned 4 of the sculptures to another museum. How many student sculptures are at the Greenville Art Museum now?
The Greenville Art Museum currently has 11 sculptures on display after receiving 3 more sculptures and then loaning out 4 sculptures.
Explanation:The Greenville Art Museum initially had 12 sculptures on display. They added 3 more sculptures to their collection, which increased the total number of sculptures to 15. Afterwards, they loaned out 4 sculptures to another museum. To find out how many sculptures are still at the Greenville Art Museum, we subtract the number of sculptures loaned out from the total.
Starting with 15 sculptures, after loaning out 4, we do the following calculation:
15 - 4 = 11 sculptures
Therefore, the Greenville Art Museum now has 11 sculptures on display.
