Step-by-step explanation:
the length of a rectangle is 2 inches more than 3 times the width find the area when the width is 2.5 inches
Step-by-step explanation:
Let's call the width of the rectangle "w".
The length of the rectangle is given as 2 inches more than 3 times the width:
l = 3w + 2
When the width is 2.5 inches, the length can be found:
l = 3 * 2.5 + 2 = 7.5 + 2 = 9.5 inches
The area of the rectangle can be found by multiplying the length and width:
A = l * w = 9.5 * 2.5 = 23.75 square inches.

Arrange each set of numbers in increasing order
the increasing order of the given numbers will be 2.2*10^3<310000<3.1*10^7<216000000.
What is increasing order?
Ascending order is the term used in mathematics to describe the ordering of integers from smallest value to highest value. A way to arrange numbers from smallest value to highest value is by using ascending order. From left to right, the order is given. Increasing order may also be used to refer to ascending order. As an illustration, consider a set of natural numbers that are arranged in ascending order: 1, 2, 3, 4, 5, 6, 7, 8, and so forth. The rising order is indicated by the less than symbol (). Descending order is the opposite of ascending order, where the numbers are organized according to decreasing value.
The given values are
216000000, 2.2*10^3, 3.1*10^7 and 310000
The increasing order:

The definition of a linear equation.A model of linear regression is one that applies the formula y=mx+b. B is the slope, and m is the y-intercept. Despite the fact because both y and x are distinct components, the previous sentence is frequently referred as a "mathematical formula with two variables." Bivariate linear equations only have two variables. The application domains of linear equations have zero solutions in all cases. The equation for a simple linear equation is Y=mx+b, where m stands for the slope and b for the y-intercept. Y=mx+b, where m stands for slopes and b for the y-intercept, is how the equation is expressed.

The equation y = 24.3x represents the number of miles, y, that Daniel can drive his
car for every a gallons of gas. Find the rate of change.
The equation y=24.3x rate of change is 24.3 .
What is rate of change?
The rate of change, which contrasts the values of the y and x variables, is expressed as a ratio. If a line is linear, constant, etc., its slope will indicate the rate of change. It is conceivable for lines to have slopes that are positive, negative, zero, or undefinable.
Here the given equation is y=24.3x.
We know that slope intercept form of the equation is y= mx+c .

Elly and Julie are 18 miles apart on a path when they start moving toward each other. Elly runs at a constant speed of 4 miles per hour, and Julie walks at a constant speed of 6 miles per hour. How long does it take until Elly and Julie meet?
Elly and Julie meet 12km long distance.
How is the distance rate formula calculated?The relationship between distance, rate, and time is shown by the equation: distance=ratetimed=rt. You will have travelled 180 miles if, for instance, your speed is 60 mph and you drive for three hours.
Use the formula d = st, which says that distance is equal to speed times time, to calculate speed, distance, or time.
Speed is calculated as distance divided by time. You can also calculate the time by dividing the distance travelled by the speed. The third input can be calculated if you know two of the inputs. Using the formula 120 x 2 = 60 mph, we can calculate the speed of a car that travels 120 miles in two hours.

Use the formula d = st, which says that distance is equal to speed times time, to calculate speed, distance, or time.
Let's call the time (in hours) that it takes for Elly and Julie to meet as "t".
We know that Elly runs 4 miles per hour, so in "t" hours, she would have run 4 * t miles.
Similarly, Julie walks 6 miles per hour, so in "t" hours, she would have walked 6 * t miles.
Since they started 18 miles apart, they would meet when the sum of the distances that each of them has covered is equal to 18 miles:
4 * t + 6 * t = 18
Solving for "t":
10 * t = 18
t = 18 / 10
t = 1.8 hours

Answer:
m<3 is 95 degrees.
Step-by-step explanation:
m<2 is 55*, the other angle is 30* because 180-150 is 30, and so by process of elimination it is 95*
Hope this helps!
Answer:
m<3=95°
Step-by-step explanation:
m<2 is vertically opposite an angle of 55°, and since vertically opposite angles are equal, we can say m<2=55°.
The unmarked angle in the triangle containing m<2 and m<3 is on a straight line with an angle of 150°. Since the angles along a straight line add to 180°, this unmarked angle=180-150°=30°.
The angles in a triangle always add to 180°, so the sum of m<3, m<2 and the unmarked angle should be 180°:
m<3+55°+30°=180°

What is arithmetic mean?The arithmetic mean is defined as the ratio of the sum of observations to the total number of observations. It can be referred to as the average of a specific set of data or the arithmetic mean.
To find the new sample mean, we need to add the new student's exercising time to the total time for the previous 7 students, and then divide by the total number of students.
The total exercising time for the previous 7 students is 7 x 5.2 = 36.4 hours.

You pay interest on any loans or borrowings of money. the portion of the loan's value that lenders use to calculate interest. Consumers can earn interest by lending money (via a bond or certificate of deposit, for example), or by putting money into an interest-bearing bank account.
Interest = Principal x Risk Percentage x Term (in months) x LIBOR
In this case, the principal is $550,000, the risk percentage is 2.0%, the term is 3 months, and LIBOR is 2.8%. So the interest paid at the end of the term is:
Interest = $550,000 x 2.0% x 3 x 2.8% = $15,660
Therefore, the interest paid at the end of the term is $15,660.
Note: I have used the risk percentage and LIBOR to calculate the interest rate which is (2.0%+2.8%) and then multiplied it with the principal and term to get the interest paid.
