round off 174 to the nearest hundred
Answer: 200
Step-by-step explanation:
174 rounded to the nearest hundred is:
200
When rounding to the nearest hundred, like we did with 174 above, we use the following rules:
A) We round the number up to the nearest hundred if the last two digits in the number are 50 or above.
B) We round the number down to the nearest hundred if the last two digits in the number are 49 or below.
C) If the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

what is 1 4/5 + (-3 4/10) show your work !
Answer:
[tex]-\frac{8}{5} = -1\frac{3}{5}[/tex]
Step-by-step explanation:
[tex]1 \frac{4}{5} = \frac{9}{5}[/tex]
[tex]-3 \frac{4}{10} = -\frac{34}{10} = -\frac{17}{5}[/tex]
Multiply the whole number by the denominator and add that to the numerator. I simplified [tex]-\frac{34}{10}[/tex] by dividing by two getting [tex]-\frac{17}{5}[/tex]. Then add [tex]\frac{9}{5}[/tex] and [tex]-\frac{17}{5}[/tex] together. Then put [tex]-\frac{8}{5}[/tex] into a mixed fraction. How many times does 5 go into 8 and what is the remainder? The answer is -1 times and the remainder is 3. The mixed fraction is [tex]-1 \frac{3}{5}[/tex].
The expression 1 4/10 + (-3 4/10 gives the value -1 3/5.
What are Mixed Fractions?Mixed fractions are type of fractions which consist of a whole number part and a fractional part.
Mixed fractions are of the form a b/c where a is the whole number part and b/c is the fractional part.
Given expression is,
1 4/5 + (-3 4/10)
Since a positive and negative combined, it becomes negative.
Also mixed fractions can be converted into improper fractions.
1 4/5 + (-3 4/10) = 1 4/5 - 3 4/10
= [(1 × 5 + 4) / 5] - [(3 × 10 + 4) / 10]
= (9 / 5) - (34 / 10)
Making the denominator of first fraction equal by multiplying with 2 on both numerator and denominator,
1 4/5 + (-3 4/10) = [(9 × 2) / (5 × 2)] - [34 / 10]
= (18 / 10) - (34 / 10)
= -16 / 10
= -1 6/10
= -1 3/5
Hence the value of the expression is -1 3/5.

[tex]\sqrt{x^2-14x+49} =x-7[/tex]
Answer: x ≥ 7
Step-by-step explanation:
You have to square both sides of the equation. You can manipulate an equation or function any way imaginable as long as it is done equally and helps the problem become easier. If we square this, the radical will cancel and we will get two trinomials equal to each other.
[tex]x^2-14x+49=(x-7)^2\\x^2-14x+49=x^2-14x+49[/tex]
We can see the two expressions are exactly equal to each other. All real numbers are solutions, besides a few. These few are when the radical is equal to a negative number. So lets set up an inequality stating that the radical must be greater than or equal to 0.
[tex]x^2-14x+49\geq 0\\(x-7)^2 \geq 0\\x \geq 7[/tex]

Which rectangular equation represents the parametric equations x =t Superscript one-half and y = 4t?
ANSWER: A
The rectangular equation that represents the parametric equation [tex]x=t^{\frac{1}{2} }[/tex] and y = 4t is:
[tex]y=4x^2[/tex] for [tex]x\geq0[/tex]
Note the given representations:
[tex]x=t^{\frac{1}{2} }[/tex]
[tex]y=4t[/tex]
Make t the subject of the formula from the expression [tex]x=t^{\frac{1}{2} }[/tex]
[tex]x^2=t^{\frac{1}{2}\times2\\\\x^2=t\\t=x^2[/tex]
Substitute [tex]t=x^2[/tex] into y = 4t
[tex]y=4x^2[/tex]
Therefore, the rectangular equation that represents the parametric equation [tex]x=t^{\frac{1}{2} }[/tex] and y = 4t is:
[tex]y=4x^2[/tex] for [tex]x\geq0[/tex]

Four fundamental factors affect the cost of money: (1) the return that borrowers expect to earn on their investments, (2) the preference of savers to spend their income in the current period rather than delay their consumption until some future period, (3) the risks associated with the investment, and (4) expected inflation. Consider the following statements that address these factors, and indicate which you think are true.
Statement 1: All things being equal, savers and investors expect to receive some amount of maturity premium as compensation for their deferred consumption.
Statement 2: Historical inflation rates, as opposed to expected future rates of inflation, should be used when calculating an investment’s nominal risk-free rate of return.
Statement 3: An investment that can provide a 10% return should attract more investment capital than an otherwise identical investment that can only provide a 6% return.
Statement 4: The inflation premium used to calculate the nominal interest rate on a five-year security should be equal to the rate of inflation expected in year 5 of the investment.
The true statements are:_______.
a. 1, 2, 3, and 4
b. 2 and 4
c. 1, 2, and 3
d. 1 and 3
Answer:
The true statements are 1 and 3
Step-by-step explanation:
Statement 1 -
All things being equal ,the savers and investors expect to receive some amount of maturity premium as compensation for their deferred consumption.
Statement 3 -
An investment that can provide a 10% return should attract more investment capital than an otherwise identical investment that can only provide a 6% return.
It is true because the return is higher than the return of identical investment therefore the higher returns will attract more investment.
Statement 2-
It is a false statement.
Historical inflation rates should not be used when calculating an investment’s nominal risk-free rate of return
But the real risk free rate and inflation premium is the part of prevailing interest rates that results from lenders compensating for expected inflation should be used
Statement 4-
It is a false statement.
The inflation premium used to calculate the nominal interest rate on a five-year security should not be equal to the rate of inflation expected in year 5 of the investment.
∴ we get
Statement 1 and 3 are true.

Answer:
change in buyer tastes.
Step-by-step explanation:
Buyers now want more donuts than the other goods.
increase in the cost of donuts is more likely to decrease the amount of donuts consumed, as they would be more expensive
consumers expecting something doesn't necessarily change anything, as they haven't yet dropped and therefore it's unlikely they'd increase the demand until they actually were cheaper.
Coffee doesn't necessarily effect donut sales, unless stated in the question.
