Answer:

751

Step-by-step explanation:

-297 + 454 = 751

Easier way of doing this is rounding 297 to 300 and doing 454 + 300, and subtracting 3.

X is all the following except<br> a term<br> a variable<br> a constant<br> an expression
lisov135 [29]

Answer: a constant

Step-by-step explanation:

A constant is a numerical expression like 2, 0,78 etc .

A variable is a alphabetical expression that vary like a,b,c,d,x,y,z.

An expression can consists of both numerical and alphabets and also any arithmetic expression like x, 2abc, 6a+2c etc

A term consist of either numbers and variables multiplied together or only numbers or variable like 2xy, x, 2ab etc.

X is all (a term, a variable , an expression) except a constant because a constant is a numerical expression.

Determine whetherfis a function from the set of all bitstrings to the set of integers if
ipn [44]

Answer:

a) Not a function

b) It is a function

c) It is a function

Step-by-step explanation:

a) f(S) is not completly well defined, becuase if the bistring has multiple zeros, you need to pick one and there is not specified method in how you would do so. Another reason for which f is not well defined as a function is that for a bistring with only 1's, f is not defined because there is no zero.

b) This is a function. f(S) returns a concrete and unique integer number for each bistring S. If the bistring has only zeros, the f(S) = 0.

c) This is well defined as a function. It compensates for the failures of the first definition:

- If multiple zeros appears in S, you pick the first one, so there is one possible value for f(S)

-If no zeros appear, f is still well defined because it takes the value 0, as specified in the definition.

Find the values of x and y : EK= 7x+5, KG= 3x+17, HK= 3y-11, KF= y+5<br>NEED ANSWER ASAP
Mice21 [21]

Answer:

<h2>x = 3, y = 8</h2>

Step-by-step explanation:

We know:

The diagonals of the parallelogram are divided in half.

Therefore

EK ≅ KG and HK ≅ KF.

We have

EK = 7x + 5, KG = 3x + 17, HK = 3y - 11 and KF = y + 5

Equations:

(1)   7x + 5 = 3x + 17

(2) 3y - 11 = y + 5

Solutions:

(1)

7x + 5 = 3x + 17       <em>subtract 5 from both sides</em>

7x + 5 - 5 = 3x + 17 - 5

7x = 3x + 12       <em>subtract 3x from both sides</em>

7x - 3x = 3x - 3x + 12

4x = 12           <em>divide both sides by 4</em>

4x/4 = 12/4

x = 3

------------------------------

(2)

3y - 11 = y + 5                <em>add 11 to both sides</em>

3y - 11 + 11 = y + 5 + 11

3y = y + 16         <em>subtract y from both sides</em>

3y - y = y - y + 16

2y = 16           <em>divide both sides by 2</em>

2y/2 = 16/2

y = 8

When originally purchased, a vehicle costing $23,000 had an estimated useful life of 8 years and an estimated salvage value of $
earnstyle [38]
The <u>correct answer</u> is:

$5,000.

Explanation:

When it is first purchased, the depreciation expense is calculated using the formula:

\text{Depreciation expense}=\frac{\text{Cost}-\text{Salvage Value}}{\text{Useful Life}}

The cost was $23,000; the salvage value was $3,000; and the useful life was 8 years:

\text{Depreciation Expense}=\frac{23000-3000}{8}=\frac{20000}{8}= \$2500

This means the value of the vehicle depreciates $2500 per year.

After 4 years, the vehicle would depreciate 2500(4) = $10,000.

This makes the new value $23000-$10000 = $13000.

Reevaluating the depreciation expense at this point, we use $13000 for the "cost" (current value), $3000 is still the salvage value, and now the total useful life was 6; we take 4 off of this, since it has already been 4 years:

\text{Depreciation Expense}=\frac{13000-3000}{6-4}=\frac{10000}{2}= \$5000

The depreciation expense in year 5 is $5,000.
