hey your answrr of this question

${{x}^{2}\:+\:30 \:= \:1000 }$

${{x}^{2}\:+\:30 \:-\:1000\:= \:0 }$

${{x}^{2}\:+\:50x\:-\:20x \:-\:1000\:= \:0}$

${(x\:+\:50)\:-\:20(x \:+\:50)\:= \:0 }$

${(x\:-\:20)(x \:+\:50)\:= \:0 }$

x - 20 = 0. or x + 50 = 0

x = 20. or x = - 50

20 , -50 are the roots of the equation

Lien Chen took out a single-payment loan for $2300.00 at 6.25% ordinary interest to pay for her federal income tax bill. If the

Assoli18 [71]

Using simple interest, it is found that she would have to pay the loan back on May 17.

<h3>Simple Interest</h3>

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

$A(t) = A(0)(1 + rt)$

In which:

A(0) is the initial amount.

r is the interest rate, as a decimal.

In this problem, the parameters are:

$A(t) = 2317.97, A(0) = 2300, r = 0.0625$

Solving for t, we have that:

$A(t) = A(0)(1 + rt)$

$2317.97 = 2300(1 + 0.0625t)$

$1 + 0.0625t = \frac{2317.97}{2300}$

$1 + 0.0625t + 1.00781304348$

$0.0625t = 0.00781304348$

$t = \frac{0.00781304348}{0.0625}$

$t = 0.125$

Considering a year has 365 days:

0.125 x 365 = 46

46 days after April 1, hence she would have to pay it back on May 17.

Identify the base in this statement:<br> 16% of 98 is 15.68

Darya [45]

Ans: The base in the statement “16% of 98 is 15.68” is 98.

The three quantities in problems involving percent are Percent, Base, amount. ‘Percent’ has the percent (%) symbol. The base is the whole amount and the amount is the amount which comes after calculation the percent of the total amount.

So, in above problem, total amount i.e. Base is 98

Percent is 16%

And, the amount is 15.68.

<span>Moreover, the base in the statement comes after the word ‘of’ and in above statement, the digit after ‘of’ is 98.</span>
