A fish swims at a speed of 12 miles per hour. A boy swims at a speed of 4.4 feet per second. 3 ft = 1 yd 5280 ft = 1 mi How much faster does the fish swim than the boy in yards per minute?
The speed by which the boy swims as fast as the fish will be 528.01 yards per minute.
What is unit conversion?It is defined as the conversion from one quantity unit to another quantity unit followed by the process of division, and multiplication by a conversion factor.
It is given that a fish swims at a speed of 12 miles per hour and a boy swims at a speed of 4.4 feet per second.
As we know,
1 mile per hour = 29.3333 yards per minute
12 miles per hour = 12 × 29.3333 yards per minute
12 miles per hour = 351.99 yards per minute
1 feet per second = 20 yards per minute
4.4 feet per second = 44 × 20 yards per minute
4.4 feet per second = 880 yards per minute
The difference in their speed is,
= 880 yards per minute - 351.99 yards per minute
= 528.01 yards per minute
Thus, the speed by which the boy swims as fast as the fish will be 528.01 yards per minute.

Roscoe rides his bike at least 10 miles but not more than 30 miles. He rides at an average rate of 10.5 miles per hour. The amount of time it takes for Roscoe to ride his bike m miles is represented by a function.
t(m)= m 10.5
What is the practical domain of the function?
All integers from 0 to 50, inclusive
All integers from 10 to 50, inclusive
All real numbers
All multiples of 20 between 0 and 1000, Inclusive
Please explain how you got your answer too, thank you!
Actually, the domain is the possible set of input values of a function that will make the function fit the specific criteria. In this case, the input value is m, where m is the number of miles that is travelled. The criteria is to travel at least 10 miles but not more than 30 miles, therefore the domain should be:
All real numbers from 10 to 30, inclusive
(should be real numbers not integer since any fractional number is included in the domain)
I cannot figure out why the choices are far from the answer.
When filing jointly, Melvin and Sylvia have a standard deduction of $11,400, they can claim one exemption for each of them for $3650 each, and they don't have any additional adjustments to income. What is their taxable income?
To calculate Melvin and Sylvia's taxable income when filing jointly, subtract their standard deduction and exemptions from their adjusted gross income.
Explanation:To calculate Melvin and Sylvia's taxable income when filing jointly, we need to subtract their standard deduction and exemptions from their adjusted gross income.
Given that their standard deduction is $11,400 and they can claim one exemption each valued at $3,650, the calculation is as follows:
Taxable income = Adjusted gross income - (Standard deduction + Exemption)
Let's say their adjusted gross income is $30,000. Plugging in the values, we get:
Taxable income = $30,000 - ($11,400 + $3,650 + $3,650)
Taxable income = $30,000 - $18,700 = $11,300
Therefore, their taxable income is $11,300.

Malik borrowed $8,000 to buy a new boat. He will pay off the loan after 4 years by paying back the principal plus 6.5% simple interest. How much will Malik pay back altogether?
A. $520 B. $2,080 C. $8,000 D. $10,080
Answer: D. $10,080
Step-by-step explanation:
The formula to find the simple interest is given by :-
[tex]S.I.=Prt[/tex], where P is principal amount , r is rate of interest ( in decimal ) and t is time period.
Given : Principal amount = $8,000
The rate of interest = 6.5% = 0.065
Time period= 4 years
Then , the simple interest will be :-
[tex]S.I.=8000\times0.065\times4=2080[/tex]
Hence, the amount which Malik pay back altogether = [tex]P+S.I.=8000+2080=\$10,080[/tex]

The difference between two numbers is 8. The lesser number is a . Write an expression for the greater number.
Final answer:
The expression for the greater number is a + 8, which is found by adding the given difference of 8 to the lesser number a.
Explanation:
The student has given us an equation to work with: The difference between two numbers is 8, and the lesser number is known as a. To find the expression for the greater number, we simply need to add the difference to the lesser number. Therefore, the greater number can be expressed as a + 8.
Let's illustrate this with an example. If the lesser number, a, is 5, then to find the greater number, we add the difference of 8 to 5, giving us 13 as the greater number.

what is 9.125 E10 in standard form
Final answer:
The number 9.125 x 10¹⁰ in standard form is 91,250,000,000.
Explanation:
The number 9.125 x 10¹⁰ in standard form is written as 91,250,000,000.
The documentation "E10" addresses increasing the number by 10 raised to the force of 10. For this situation, "E10" signifies we really want to increase 9.125 by 10¹⁰.
To work out this, we move the decimal guide 10 spots toward the right, bringing about an extremely huge number:
9.125 E10 = 9,125,000,000
In this way, 9.125 E10 in standard structure is 9,125,000,000.

thanks help would be very well apreciated :)
Square root helps to find the factor of a number which when multiplied by itself gives us the number. The value of √1.69 is √1.3.
What is square root?Square root can be defined as the process of finding a number which is a factor of a number when multiplied by itself to get a number.
In order to evaluate the value of √1.69, we will convert decimal value 1.69 into a fraction, therefore, the fraction can be written as,
[tex]1.69 = \dfrac{169}{100}[/tex]
Now, using this equivalent value of 1.69, the evaluation can be written as,
[tex]\sqrt{1.69}\\\\= \sqrt{\dfrac{169}{100}}[/tex]
Further, using the exponential property the value can be written as,
[tex]= \sqrt{\dfrac{169}{100}}\\\\\\={\dfrac{\sqrt{169}}{\sqrt{100}}}\\\\\\=\dfrac{13}{10}\\\\=1.3[/tex]
Hence, the value of √1.69 is √1.3.
