14 is 8% of the number 175, and 16% of 175 is equal to 28.

To find a number that 14 is 8% of, we can set up the equation:

14 = 0.08 × x

Dividing both sides by 0.08:

14 / 0.08 = x

x = 175

Therefore, 14 is 8% of 175.

To find 16% of 175, we can multiply 175 by 0.16:

16% of 175

= 0.16 × 175

= 28.

The area of a rectangular rug given the dimensions 6ft by 3.5ft can be calculated by multiplying these measurements. The correct mathematical expression representing this concept is 6 x 3.5. When performed, it results in an area of 21 square feet.

To find the area of a rectangular rug, you need to multiply the rug's length by its width. Given that the rug is 6 ft on one side and 3.5 ft on the other side, you would multiply 6 ft by 3.5 ft.

So, the correct mathematical expression to find the area of the rug is 6 x 3.5.

The area of the rink is 184.8 m²

From the problem above we know the measurement of the ice rink is

22 x 8.4 m

to calculate the area = length x width

                                   = 22 x 8.4

Here is how to solve the decimal multiplication, we are going to multiply them as a whole number. The different is the placement of the decimal point in the answer. Using the standard algorithm method, the calculation would be:

 22             ⇒ whole number (no decimal place)

 8.4  x        ⇒ 1 decimal place

 88          

176  +

184.8           ⇒ 1 decimal place

The first factor 22 doesn't decimal place

The second factor 8.4 has one decimal place

The result will has one decimal place (0+1=1)

The verbal statement '6 times the sum of a number t and 5 is s' is translated into the algebraic equation 6(t + 5) = s, which is a linear equation used to solve for either t or s.

The student's question involves creating an algebraic equation from a verbal statement. In this case, the expression '6 times the sum of a number t and 5 is s' can be translated into an algebraic equation. To do so, we first represent the sum of the number t and 5 as (t + 5). We then multiply this sum by 6 to represent '6 times the sum', which gives us the equation 6(t + 5) = s.

This equation allows us to solve for the number t when s is known, or vice versa. It is a basic linear equation that can be used in various mathematical problems to determine the value of s given a specific t, or to find t when s is known.

The value after rounding 26,000 to its nearest ten thousands is 30,000.

Given,

26,000

We need to round to its nearest ten thousands.

Example:

235678

8 - ones

7 - tens

6 - hundreds

5 - thousands

3 - ten thousands

2 - hundred thousands

Round 26,000 to its nearest ten thousand.

26,000

2 is in ten thousands place value.

So we need to round either to 20,000 or 30,000.

Since 26000 > 2499 we will round to 30,000.

= 30,000

Thus 30,000 is our answer.

The simplified expression for the cost of a concert ticket with a 3% sales tax is t(1.03). For an original ticket price of $72, the total cost after adding the sales tax is $74.16.

The cost of a ticket t to a concert with a 3% sales tax can be simplified by first expressing the total cost as a single expression. Simplify the expression t + 0.03t by factoring out t, which gives us t(1 + 0.03) or t(1.03). This shows that the total cost is 103% of the original ticket price.

To find the total cost after the sales tax for a ticket initially priced at $72, simply multiply the original price by 1.03:

$72 × 1.03 = $74.16

Thus, the total cost of the concert ticket after applying the 3% sales tax is $74.16.

Answer:D

Step-by-step explanation:

X is the budget

So you already know  you have to subtract 2070 for salaries then 1/4 of that that is the answer the only way that can be expressed is by D

The function that can be used to find the amount in dollars spent on monthly activities is D. f(x) = x-2070 / 4

Monthly budget of the organization = x

Amount spent on salaries = 2070

Amount spent on monthly activities will be calculated thus:

= 1/4 × (x - 2070)

= (x - 2070) /4

Therefore, for the information and the calculation given above, it can be inferred that the correct option that suits the expression will be D.

Answer:

a - b is also a rational number.

Step-by-step explanation:

 Given : a and b be rational numbers.

We have to check whether  a - b rational or irrational.

Since, Given  a and b be rational numbers.

Let us consider any two rational numbers,

[tex]a=\frac{2}{3}[/tex] and [tex]b=\frac{1}{3}[/tex]

we determine a - b as,

[tex]a-b=\frac{2}{3}-\frac{1}{3}[/tex]

Simplify, we have,

[tex]a-b=\frac{2-1}{3}=\frac{1}{3}[/tex]

Which is a rational number.

Thus, a - b is also a rational number.
