Remember that dividing by a number is the same as multiplying by its reciprocal. To get a number's reciprocal, flip the numerator and denominator around.

In this case, 3/5's reciprocal is 5/3. With this information in mind, flip 3/5 to it's reciprocal, change the division sign to multiplication, then multiply as such:

[tex]\frac{7}{8} \times \frac{5}{3}=\frac{35}{24}[/tex]

Your final answer is 35/24.

Now firstly, we want to convert these mixed fractions into improper fractions. To convert them, multiply the whole number by the denominator then add the numerator and that's your new numerator. In this case:

[tex]2\frac{1}{10}=\frac{2*10+1}{10}=\frac{21}{10}\\\\1\frac{1}{5}=\frac{1*5+1}{5}=\frac{6}{5}\\\\\frac{21}{10}\div \frac{6}{5}[/tex]

Next, we want to convert this expression to multiplication. Similar to before, convert 6/5 to its reciprocal, change the multiplication sign to division, and multiply as such:

[tex]\frac{21}{10}\times \frac{5}{6}=\frac{105}{60}[/tex]

Now you may think that 105/60 is the right answer, however we can simplify it further. The numerator and the denominator have a GCF, or greatest common factor, of 15. With this, divide the fraction by 15/15 as such:

[tex]\frac{105}{60}\div \frac{15}{15}=\frac{7}{4}[/tex]

Your final answer is 7/4.

Answer is 4.04 by adding both of the time of each then subtracting then from each others time

Answer:

4.04

Step-by-step explanation:

take the number 14.19 and add that to 13.78, you get 27.97.

Now take 15.77 and add that to 16.24, you get 32.01.

Now take 32.01 and 27.97 and subtract them.

You get 4.04.

And thats your answer

Answer:

Shyam's original investment was $4000.

Step-by-step explanation:

Suppose, Shyam's original investment was  [tex]x[/tex] dollar.

In the first year, his stock increased 20%. So, the value of the stock will be: [tex](x+0.20x)=1.20x[/tex] dollar.

He paid his stock broker $300 and then lost $450. So now, the value of the stock will be:  [tex](1.20x-300-450)=(1.20x-750)[/tex] dollar.

He then withdrew $500, so the value of the remaining investment [tex]=(1.20x-750-500)=(1.20x-1250)[/tex] dollar and this remaining investment doubled now.

So, the value of the investment now [tex]=2(1.20x-1250)[/tex] dollar, which is given as $7100.

Thus, the equation will be.......

[tex]2(1.20x-1250)=7100\\ \\ 2.40x-2500=7100\\ \\ 2.40x=7100+2500=9600\\ \\ x=\frac{9600}{2.40}=4000[/tex]

So, Shyam's original investment was $4000.

Let the consecutive odd numbers be( x) and (x+2).

According to given condition.

(x)+(x+2) =284

solving  x+x+2 =284

2x+ 2 =284

subtracting 2 both sides

2x+ 2-2 =284-2

2x =282

dividing 2 both sides

x=141

as the second integer is (x+2) so

x+2 =141+2= 143

so integers are 141 and 143.

The point (1,1) has been moved 3 spots to the right to get to (4,1). The entire equation of the V shaped curve will also move 3 spots to the right. So that's how we go from |x| to |x-3|. Note how plugging in x = 4 leads to y = |x-3| = |4-3| = |1| = 1

Using the multiplication method, we find that 16 times 60 equals 960.

To find the product of 16 times 60, we can use the method of multiplication. The multiplication method is a straightforward way to find the product of two numbers by multiplying each digit separately and adding the results.

1. Write down the two numbers being multiplied: 16 and 60.

2. Start by multiplying the rightmost digit of the bottom number (60) with the top number (16). In this case, multiply 0 with 16, which equals 0.

3. Write down the result (0) below the line.

4. Now, multiply the next digit of the bottom number (6) with the top number (16). Multiply 6 with 16, which equals 96.

5. Write down the result (96) below the line, shifted one position to the left.

6. Finally, add the two results together: 0 + 96 = 96.

So, the product of 16 times 60 is 960.

The opposite of 4 is -4 for additivity and 1/4 for multiplicity.

In mathematical language, opposite of a number means inverse of a number and 2 inverses of the number are possible. One is additive inverse, while the other is multiplicative inverse.

To calculate an additive inverse of 4:

Let x be an additive inverse of 4, then

4+x=0

On transposing,

x=-4

Let y be multiplicative inverse of 4, then

4 x y=1

On transposing,

y=1/4

It'd be c) g(x)=(x-4)2+9

Answer : C

The function [tex]f(x)= x^2[/tex] has been translated 9 units up and 4 units to the right to form the function g(x)

For 9 units up, we add 9 at the end of f(x)

f(x) + 9

so equation becomes [tex]f(x)= x^2 + 9[/tex]

For 4 units right , we subtract 4 from x  in f(x)

f(x-4)

So the equation becomes [tex]f(x) = (x-4)^2 + 9[/tex]

Hence [tex]g(x) = (x-4)^2 + 9[/tex]

-1 = 3r + 2r

-1 = 5r          Combine like terms

[tex]\frac{-1}{5}[/tex] = [tex]\frac{5r}{5}[/tex]      Divide both sides.

Final answer: -0.2 = r

Answer:

C would be able to verify the equation.

Step-by-step explanation:

In order to tell if any equation is a inverse, you can plug one equation in for x in the other. If the result is y = x, then it is an inverse. C is putting f(x) in for x in the g(x) equation. If you multiply this out, it comes out to y = x

A function assigns the values. The correct option is C.

A function assigns the value of each element of one set to the other specific element of another set.

If two functions are inverse of each other, then their composition is equal to the variable, in this case, it is x. Since f(x)=3x, while g(x)=1/3x, therefore, we can write,

g(f(x))

= 1/ 3(3x)

Hence, the correct option is C.

Maria has completed 60% of her total deliveries this week. This was calculated by creating a ratio of completed deliveries to total deliveries, converting this ratio to a decimal, and then converting the decimal to a percentage.

To find what percentage of deliveries Maria has completed, we start by creating a ratio of completed deliveries (48) to total deliveries (80). This ratio is expressed as a fraction, so we write it as 48/80.

Next, we convert this fraction to a decimal by dividing the numerator (top number) by the denominator (bottom number). So, 48 ÷ 80 = 0.6

To convert the decimal to a percentage, we multiply by 100, so 0.6 x 100 = 60%.

Therefore, Maria has completed 60% of her total deliveries so far.

To calculate the percentage of total deliveries Maria has completed, divide the number of completed deliveries by the total number of deliveries and multiply by 100. Thus, Maria has completed 60% of her total deliveries.

To find out what percentage of total deliveries Maria has completed, we can use the method of finding a percentage of a whole. Essentially, this involves taking the number of completed deliveries, dividing it by total number of deliveries and then multiplying by 100.

In Maria's case, she's completed 48 deliveries out of a total of 80 deliveries. Therefore:

Percentage = (Number of completed deliveries / Total deliveries) x 100

So the percentage of completed deliveries = (48 / 80) x 100 = 60%

Therefore, Maria has completed 60% of her total deliveries.

Answer:

Rational; irrational; irrational.

Step-by-step explanation:

a/3b is a rational number, as it is represented by a fraction and b ≠ 0.  This means the first blank is "rational."

√5 is an irrational number.  This means the second blank is "irrational."

Since we have an irrational number set equal to a rational number, this is a contradiction.  This means our original assumption is wrong, and the number is irrational.  This is the third blank.

There are Rational, irrational, and irrational are the correct options respectively.

A rational number is defined as a numerical representation of a part of a whole that represents a fraction number.

It can be a/b of two integers, a numerator a, and a non-zero denominator b.

Given Number = 3√5

We have to prove that 3√5 is an irrational number.  

Let us assume 3√5 is a rational number.

Because it is represented as a fraction and b ≠ 0, a/3b is a rational number. This implies that the first blank is "reasonable."

The number √5 is irrational. This indicates that the second blank is "irrational."

This is a contradiction since we have an irrational number set equal to a rational number. This signifies that our initial assumption was incorrect, and the number is irrational.

Therefore, the assumption is wrong, and the product is irrational.

The counter-example is 10. the correct option is D.

Absolute value refers to the removal of any preceding minus sign and the treatment of all numbers as positive (or zero).

Given that If |n| is a positive number, then n is a negative number.

Take all the negative values of n for the function.
