Ellentown college has appoximately 3 times 10 to the 3 power students and pengrove university approximate 30,000 students. how many times as much is the number of students at pengrove university as the number of students at Ellwntown college

Answer:

26.

Step-by-step explanation:

You just have to do 22.10 ÷ 0.85.

Final answer:

By dividing the total cost spent on drinks by the cost of each drink ($22.10 ÷ $0.85), we find that 26 people attended the Lopez family picnic.

Explanation:

To determine how many people attended the Lopez family picnic, we need to divide the total cost spent on drinks by the cost of each drink. Since the Lopez family spent $22.10 on drinks and each drink cost $0.85, we perform the following calculation:

Total cost spent on drinks ÷ Cost of each drink = Number of people

$22.10 ÷ $0.85 = 26 people

Therefore, 26 people attended the Lopez family picnic.

Answer:

Domain of y=[tex]\sqrt[4]{x-1}[/tex]: is x>=1

Interval notation: [1,∞)

Step-by-step explanation:

We have y=[tex]\sqrt[4]{x-1}[/tex]

1) The domain of a function is the set of x values for which the function is real and defined.

2) So, x-1 should be positive means x-1>=0, because fourth root of any negative value would be a complex number and not a real number.

3) Now we solve the inequality x-1>=0

4) Adding 1 to both sides of the inequality we get,

x-1+1 > = 0+1

5) Cancel out -1 and +1 from the left side

6) We get x>=1

It concludes that for the domain of the given function, the x value must be greater than or equal to 1

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.

i think it is 0.33...i could be wrong.

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.

Snow in March = 1.4f cm

Step-by-step explanation:

Given that

Snowfall in February in Delphine's house = f cm

Now, it is given that In march Delphine's house had 40% more snowfall than Febraury. So, this can be written in equation form as follows :

Snow in March = Snow in Febraury + 40% of Snow in Febraury

Snow in March = f + 40 % of f

Snow in March = f + 0.4f

Snow in March = 1.4f cm

$25 821.69

Step-by-step explanation:

The formula for the future value (FV) of an investment is

FV =PV(1 + r/n)^nt

FV = 20 000(1 + 0.087/2)^(2×3)

FV = 20 000(1 + 0.0435)⁶

FV = 20 000(1.0435)⁶

FV = 20 000 × 1.291 0847

FV = $25 821.69

We have $440 to spend on fliers

Step-by-step explanation:

Budget = supplies + fliers

555 = 115 + fliers

Subtract 115 from each side

555-115 = 115-115 + fliers

440 = fliers

We have $440 to spend on fliers

Answer:

(a)

Given expression: 49% of 162

we can write 49% as [tex]\frac{49}{100}[/tex]

then;

[tex]\frac{49}{100} \times 162 = \frac{49 \times 162}{100} = \frac{7938}{100}=79.38[/tex]

Therefore, the estimate of the given expression is, 79.38.

(b)

Using mental math to calculate 49% of 162.

Mental math is used as a way to calculate an estimate quickly.

We can write 49% = 50% -1%

(50%-1%) of 162 = 50% of 162 -1% of 162

so,

50% of 162 = [tex]\frac{50}{100} \times 162 = \frac{1}{2} \times 162 = 81[/tex]

and

1% of 162 = [tex]\frac{1}{100} \times 162 = \frac{162}{100} = 1.62[/tex]

Now, subtract these we get;

81 - 1.62 = 79.38

Therefore, by using mental math 49% of 162 is, 79.38

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

-2(1 - 4x) = 3x + 8

The first step is to distribute the -2

-2*1 -2(-4x) = 3x+8

-2+8x = 3x+8

Subtract 3x from each side.

-2+8x-3x = 3x-3x+8

-2+5x=8

Add 2 to each side

-2+2 +5x=8+2

5x=10

Final answer:

Assuming a square garden with each side being 8 feet, 50% of the space allocated to daisies would be 32 square feet.

Explanation:

Mr. King is dividing his garden evenly for tulips and daisies, meaning each flower type will occupy 50% of the garden's area. The length of the garden is given as 8 feet, but the width is not mentioned. To determine the actual area for daisies, we need both dimensions of the garden. However, if we assume that the width is also provided or the garden is square (8 feet by 8 feet), then the total area of the garden is 64 square feet (8 feet * 8 feet).

Now, to find the space filled with daisies, we calculate 50% of the total area:

0.50 * 64 square feet = 32 square feet.

Therefore, if the garden is a square and the other dimension equals the given length, the space filled with daisies will be 32 square feet.

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.
