Final answer:

To solve the expression 5 ∙ 23, we multiply 5 by 23, which gives us the answer 115.

Explanation:

The student has asked to find the value of 5 multiplied by 23. In mathematics, when we see an expression like 5 ∙ 23 without any parentheses, it simply means we need to multiply the number 5 by 23 to get the answer. Let's perform this calculation step by step:

First, we write down the number we need to multiply, which is 5.

Next, we write down the number by which we are multiplying, which is 23.

Now we multiply these two numbers: 5 * 23 = 115.

The answer to the expression 5 ∙ 23 is 115.

The value of [tex]\(5 \cdot 2^3\)[/tex] is 40.

To find [tex]\(5 \cdot 2^3\)[/tex], adhere to the order of operations. The expression involves exponentiation before multiplication.

First, compute the exponent: [tex]\(2^3\)[/tex] equals [tex]\(2 \times 2 \times 2\)[/tex], resulting in 8.

Then, multiply this value by 5, yielding [tex]\(5 \times 8\)[/tex], which simplifies to 40.

The process follows the principles of the order of operations (PEMDAS/BODMAS), ensuring accurate computation.

Thus, [tex]\(5 \cdot 2^3\)[/tex] equals 40.

Complete Question:

The number 30 tens is equivalent to three hundred.

In the decimal system, there are ten units in a group called a "ten." Likewise, there are ten tens in a group called a "hundred."

Therefore, one hundred is equal to ten tens.

Since we know that one hundred is equal to ten tens, calculate how many hundreds are equivalent to 30 tens.

Divide 30 by 10 to find out how many groups of ten are present:

= 30 tens ÷ 10

= 3

Therefore, 30 tens are equal to 3 hundreds.

Answer:

1.2

Step-by-step explanation:

The x in each point is 3 so we can leave that alone.

Then we subtract.

2.6 - 1.4 = 1.2

The distance between the points (3, 2.6) and (3, 1.4) will be 1.2 units.

Let one point be (x, y) and another point be (h, k).

Then the distance between the points will be

D² = (x – h)² + (y – k)²

Point A is at (3, 2.6) and point B is at (3, 1.4) on a coordinate grid.

(x, y) ⇒ (3, 2.6)

(h, k) ⇒ (3, 1.4)

Then the distance between the points (3, 2.6) and (3, 1.4) will be

D² = (3 - 3)² + (2.6 - 1.4)²

D² = 0 + 1.2²

D = 1.2 units

The domain of the function y = 1725 - 75x, representing money left in a lunch account, is between 0 and 20 weeks. The range is the amount of money, from $225 to $1725.

The equation y = 1725 - 75x represents the amount of money left in a lunch account after x weeks. If we consider the function f(x) for 0 ≤ x ≤ 20. The domain of this function, which is the set of allowable values for x, is from 0 to 20, inclusive. This means that x can take on any real number value between 0 and 20. For the range, we calculate the minimum and maximum values of y using the equation, which are y when x = 0 and y when x = 20 respectively. For x = 0, y = 1725 and for x = 20, y = 1725 - 75(20) = 1725 - 1500 = 225. So the range of y is from 225 to 1725 dollars.

To find the total cost of three shirts priced at $49.96 each before tax, multiply the price of one shirt by three, resulting in a total of $149.88.

The question concerns the calculation of the total cost of three shirts before tax in Mathematics.

To answer it, we simply need to multiply the original price of one shirt by the quantity desired.

Since one shirt is priced at $49.96, the cost for three shirts can be found by performing the following multiplication:

$49.96 × 3 = $149.88

Therefore, the total cost of three shirts before tax is $149.88. This calculation is a straightforward example of applying basic multiplication skills to find the total cost of multiple items.

Thus, for the given value of originally priced at $49.96, the cost  before tax is found to be $149.88.
