Answer:

6

Step-by-step explanation:

5^2+6=31

25+6=31

31=31

proved

One-third of the number is at least 5 units from 31. The number is 78.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that one-third of a number is at least 5 units from 31. The unknown number is x.

( 1 / 3 )x + 5 = 31

x + 15 = 31 x 3

x + 15 = 93

x = 93 - 15

x = 78

Therefore, one-third of the number is at least 5 units from 31. The number is 78.

Think of it this way what if an exponent had 1 so like 10^1

that still equals 10, and does not change anything, so you need to add one more to the exponent as the first number does not change how many types the number is multiplied. Hope this helps

Answer:

$35.53

Step-by-step explanation:

12.32+11.23+7.89=31.44

31.44*0.08(for the 8% tax)=2.52

31.44*0.05=1.57

31.44+2.52+1.57=35.53

Answer:

PM = 58

Step-by-step explanation:

The question tells us that the full line has a value of 6x+56. The midpoint divides this line into equal pieces. We are also given the value of half (MQ) of the line (5x+8). By subtracting 5x+8 from 6x+56, we can figure out the value of the other half of the line (PM).

This gives us the expression for PM: x+48

Now, since these are both the two parts of the midpoint, by definition, we know they're equal.

You equal both equations and get x=10

You plug in 10 as x in the expression we got for PM (10+48), which gives us the value 58.

For a basic subscription, a cable television provider charges an activation fee of $60, plus $125 per month. What linear function represents the total cost of basic cable subscription for t months? What is the total cost for two years of service?

y=125x+60

$310 for 2 months

$3060 for 2 years

Step-by-step explanation:  let x be the number of months

y=125x+60

y=125(2)+60

y=310 dollars for two months

y=125(24)+60

y=3060 dollars for two years

Answer:

f(- 4) = 13

Step-by-step explanation:

We require to find the value of t which makes f(t) = 13

Equating the right sides gives

- 2t + 5 = 13 ( subtract 5 from both sides )

- 2t = 8 ( divide both sides by - 2 )

t = - 4

Then

(f(- 4) = 13

Answer:

32,000 or 32 thousand

Step-by-step explanation:

When looking at thousands, we must determine if the hundreds place has more than 5 which would be half of a thousand. So... if there would have been 32500, then the answer would have been 33,000 because there were 500.

Since there are only 450, we are going to have to round back to 32,000 since the number isn't large enough.

Arrays are dataset that are represented in rows and columns. Rosa's claim is correct.

An array is a linear data structure that collects elements of the same data type and stores them in contiguous and adjacent memory locations.

From the question, we have:

6 rows and 8 columns

The number (n) of elements in the array is: n = Rows × Columns.

So, we have: n = 6 × 8 =48

Express as sum of three numbers, that is n=12+16+20

Express each term as a product, that is n=2 × 6 + 4 × 4 + 4 × 5

The above expression means that, the array can be split to:

An array of 2 by 6

An array of 4 by 4

An array of 5 by 4

Hence, Rosa is correct.
