Answer:
0.25 in²
Step-by-step explanation:
This is all basic stuff of conversion and multiplication
Option D, The area of the rectangle is 6/24 square inches.
The area of a rectangle is calculated by multiplying its length and width. Given a rectangle with a length of 3/8 inch and a width of 2/3 inch, we can find the area using the formula:
Area = Length × Width
Substitute the given values:
Area = (3/8) × (2/3)
To multiply these fractions, multiply their numerators and their denominators:
Area = (3 × 2) / (8 × 3) = 6 / 24
After simplifying the fraction 6/24, we get 1/4.
Therefore, the area of the rectangle is 1/4 square inches. Among the answer choices, Option D (6/24) is equivalent to 1/4, so the correct answer is Option D.

Find the circumcenter of triangle ABC with vertices A(-2,4),B(-2,-2),and C(4,-2)
The circumcenter of the triangle ABC with vertices A(-2,4), B(-2,-2), C(4,-2) is found by locating the intersection of the perpendicular bisectors of the sides. It is calculated to be the point (1,1).
Explanation:The circumcenter of a triangle is the point where the perpendicular bisectors of the sides intersect. It is equidistant from all three vertices of the triangle. To find the circumcenter of triangle ABC with vertices A(-2,4), B(-2,-2), and C(4,-2), we first find the midpoints of the sides and then the equations of the perpendicular bisectors.
The midpoint of AB is (-2, 1) and the midpoint of BC is (1, -2). The slope of AB is undefined and that of BC is 0. Hence, the slopes of the perpendicular bisectors are 0 and undefined respectively. The equation of the line passing through (-2,1) with slope 0 is y = 1. The equation of the line passing through (1,-2) with undefined slope is x = 1. The intersection of these two lines (circumcenter) is (1,1).

The area of the rectangular slab of foam insulation is 30 square meters. Find the dimensions of the slab.
m (smaller value)
m (larger value)
The dimensions of the slab are:
Length = 3 meters
Width = 10 meters
To find the dimensions of the rectangular slab, we'll use the given area and the expressions for length and width.
Given:
Area = 30 square meters
Length = w
Width = 2w + 4
We can use the formula for the area of a rectangle to solve for w:
Area = Length × Width
Substituting the given values:
30 = w × (2w + 4)
Expanding the equation:
30 = 2w² + 4w
Rearranging the equation in standard quadratic form:
2w² + 4w - 30 = 0
Now, we can solve this quadratic equation using factoring, completing the square, or the quadratic formula. Let's use the quadratic formula:
w = (-b ± √(b² - 4ac)) / (2a)
In this case, a = 2, b = 4, and c = -30. Substituting these values into the formula:
w = (-4 ± √(4² - 4(2)(-30))) / (2(2))
w = (-4 ± √(16 + 240)) / 4
w = (-4 ± √256) / 4
w = (-4 ± 16) / 4
We have two possible solutions for w:
w = (-4 + 16) / 4 = 12 / 4 = 3
w = (-4 - 16) / 4 = -20 / 4 = -5
Since the width of the slab cannot be negative, we discard the second solution (w = -5).
Therefore, the width of the slab (w) is 3 meters.
Now, we can find the length using the given expression:
Length = w = 3 meters
Therefore, the dimensions of the slab are:
Length = 3 meters
Width = 2w + 4 = 2(3) + 4 = 6 + 4 = 10 meters

The high school courtesy club bought red and black ink pens for Teacher Appreciation Day. The club bought 75 pens in all. Each black pen cost $1.75, and each red pen cost $2.00. The club spent $137 altogether for the pens. How many black pens did the club buy?
13
23
48
52
Answer:
52
Step-by-step explanation:
By solving the system of equations derived from the problem, we get that the club bought 23 black pens.
Explanation:Let's denote the number of black pens as 'b' and the number of red pens as 'r'. According to the problem, we have two equations: b + r = 75 (there were 75 pens in total) and [tex]1.75b + 2r = 137[/tex] (the total cost of the pens was $137).
Now, we can solve this system of equations. From the first equation, we can express 'r' as r = 75 - b. Substitute this into the second equation: [tex]1.75b + 2(75-b) = 137.[/tex], simplifying this gives b = 23. So, the club bought 23 black pens.

A new car has factory installed tires that are P205/60R16. The owner wants to a little bigger and opts for the set of P215/75R15. How fast is the car actually going if the speedometer is at 80?
Answer:
The car is actually moving at a speed more than 80 miles per hour
Step-by-step explanation:
Theoretically, since the speedometer of the car is at 80, it means the car is having a speed of 80 miles / hr. The car should move by a distance of 80 miles in an hour.
But, practically changing the tire size can affect the speedometer accuracy because larger tire covers more ground in each complete revolution. So, the actual speed is higher than the speedometer reads.
Example
Suppose a car comes with factory-installed tires which are 21.8 inches in diameter. It means that the circumference of each tire is 68.5 inches. Now if we replace the old tires with new tires having 24.6 inches as diameter then each new tire has a circumference of 77.3 inches. This means the car travels almost 10 inches more with each complete revolution. This can tremendously affect the reading on the speedometer. The speedometer will now indicate a speed which is too slow by almost 13%. When the speedometer reads 60 miles/hour, the car will actually be traveling at a speed of 67.7 miles/hour.

3.a volunteer has 12 pounds of birdseed to put in bird feeders in all of the city parks. there are 3 ¼ Cups of birdseed in pounds, and each bird feeder holds about ¾ cups of birdseed.how many birds feeders can the volunteer fills completely?
Answer:
4 Bird Feeders
Step-by-step explanation:
3 1/4 ALSO is 13/4
13/4 dived by 3/4 or 13/3 witch is 4 and some extra so it can only fill four feeders fully
Answer:
52 bird feeders
Step-by-step explanation:
First, you must determine how much birdseed the volunteer has in cups. To do this, multiply the 12 pounds by the 3 1/4 cups, as there are 3 1/4 cups in one pound. This means the volunteer has 39 cups of birdseed.
Then you must divide the amount of birdseed the volunteer has (39 cups) by the amount of birdseed needed to fill a bird feeder (3/4 cups), which will give you the amount of bird feeders the volunteer can fill (52 bird feeders).

The amount still owed on a loan is called what ?
Final answer:
The amount still owed on a loan is called the principal, which is the original amount borrowed minus any repayments made toward it. Interest is charged on this amount, and loans are assets to banks which can be sold in the secondary loan market.
Explanation:
The amount still owed on a loan is referred to as the principal. When you make a payment on a loan, such as a credit card or a mortgage, part of it covers the principal, which is the original amount borrowed, and the rest goes toward paying off interest. Interest is the charge for borrowing the money and is calculated based on the remaining balance of the loan. When a borrower takes out a mortgage loan, for instance, they will repay both the principal and interest over the term of the loan, which often spans many years, such as in a 30-year mortgage.
Banks consider loans as assets because they are legally binding agreements where the borrower must make payments over time. In the banking industry, the value of a loan can also be determined by what another party is willing to pay for it in the secondary loan market, where loans are bought and sold between financial institutions after being originated in the primary loan market.
An example of this can be seen when a borrower owes more on their mortgage than the actual market value of the property, resulting in negative equity. However, as the loan is paid down, the equity typically increases, which is the value of the property minus the remaining loan balance.
