Jiri is seventeen years old.

Answer:

J=Jiris

P=2J

P+J-51

Use substitution to solve

2J + J = 51

3J = 51

J=17

Plug 17 into one of the equations

J=17, P + J = 51

P + 17 = 51

P= 34

So Pamela is 34 and Jiris is 17

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).

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).

Number of red blood cells = [tex]4.5*10^{6}[/tex]

Number of white blood cells = 5000 or we can write this as [tex]5*10^{3}[/tex]

We have to find how many times more red blood cells are there than white in the sample. so we will divide the two to get the answer.

[tex]\frac{4.5*10^{6}}{5*10^{3}}[/tex]

= [tex]0.9*10^{3}[/tex]

= [tex]9*10^{2}[/tex] = 9*10*10 = 900

Hence, the red blood cells are 900 times more than white blood cells.

Answer:

Red blood cells are 900 times of white blood cells in the blood sample of Laura.

Step-by-step explanation:

Sample of Laura's blood sample contains number of red plus cells = 4.5[tex]10^{6}[/tex] and number of white blood cells = 5×[tex]10^{3}[/tex]

Now we calculate the ratio of red blood cells and white blood cells

= 4.5×[tex]10^{6}[/tex]÷5[tex]10^{3}[/tex]

= 4.5×[tex]10^{3}[/tex]÷5

= 4500÷5

Step-by-step explanation:

By solving the system of equations derived from the problem, we get that the club bought 23 black pens.

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.

Answer:

Step-by-step explanation:

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.

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.

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).

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.

Complete Question :

Answer:

The answer is 9 square feet.

The area of the square tabletop is calculated using the formula A=s². Given that the length of one side is 3 feet, we substitute this into the formula to get A = 3², which equals to 9 square feet.

Janice is trying to calculate the area of a square tabletop using the formula A=s², where A represents the area and s stands for the length of one side. Since the length of one side of the square (s) is given as 3 feet, we can substitute this value into the formula, resulting in A = 3².

Squaring 3 (i.e., multiplying 3 by itself) gives us 9, so the calculated area of the square tabletop is 9 square feet.

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
