Hamid has gained weightHe now weighs 88kg, which is 10% higher than his normal weight.

What is Hamid's normal weight?

Answers

If we let x be Hamid's normal weight, 10% of the normal weight can be expressed as 0.10x. The equation that would let us better visualize the problem,
(1.10)x = 88

The value of x from the equation is 80.

Therefore, the answer is 80 kg.

The normal weight of Hamid is 80 kg.

Step-by-step explanation:

Given information:

The current weight of Hamid is 88 kg.

Let , $W$ is the normal weight of hamid.

Now , if he is having 10% extra weight

So,

The value 88 is sum of normal weight and 10% of the normal weight

So,

$W+0.10* W=88\n1.10* W=88\nW=80$

Hence, the normal weight of Hamid is 80 kg.

consider a job that pays $100,000 per year federal income taxes 19% and state income tax is 7% what is the annual total of the required deductions of federal and state income tax

Answers

Answer:

$26,000.

Step-by-step explanation:

We have been given that a job that pays $100,000 per year federal income taxes 19% and state income tax is 7%.

The annual total of the required deductions of federal and state income tax would be $19\%+7\%=26\%$ .

To find the total amount, we will find 26% of $100,000.

$(26)/(100)* \$100,000$

$26* \$1000$

$\$26,000$

Therefore, the annual total of the required deductions of federal and state income tax is $26,000.

first multiply 100,000 and 19% equaling 19,000

Then multiply 100,00 and 7% equaling 7,000

Lastly add 7,000 and 19,00 together to get your answer

Answer: 26,000

Using the quadratic formula to solve 5x = 6x2 – 3, what are the values of x?

Answers

   5x = 6x² - 3
5x - 5x = 6x² - 5x - 3
       0 = 6x² - 5x - 3
   x = -(-5) ± √((-5)² - 4(6)(-3))
      2(6)
   x = 5 ± √(25 + 72)
      12
   x = 5 ± √(97)
   12
x = 5 + √(97) U x = 5 - √(97)
   12 12
$the\ values\ of\ x\ is\ (5 +/- √(97))/(12).$

The value of x are; x = 5 + √(97)/12 and x = 5 - √(97)/12.

What is a quadratic equation?

A quadratic equation is the second-order degree algebraic expression in a variable.

The standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

Given;

5x = 6x² - 3

Subtract 5x on both sides

5x - 5x = 6x² - 5x - 3

0 = 6x² - 5x - 3

x = -(-5) ± √((-5)² - 4(6)(-3)) / 2(6)

x = 5 ± √(25 + 72)/ 12

x = 5 ± √(97)/ 12

The value of x are;

x = 5 + √(97)/12

x = 5 - √(97)/12

Mike purchased 3 DVD's and 14 video games for $203. Nick went to the same store and brought 11 DVD's and 11 video games for $220. How much is each video game and each DVD?

Answers

$x-cost\ of\ DVD\ny-cost\ of\ video\ game\n\n \left \{ {{3x+14y=203\ \ \ } \atop {11x+11y=220\ \ } \right. \n\n From\ first\ second:\n11x=220-11y\ \ \ \ |:11\nx=20-y\n\nSubstitute\ to\ first:\n3(20-y)+14y=203\n60-3y+14y=203\n-3y+14y=203-60\n11y=143\ \ \ \ |:11\ny=13\n\nx=20-13=7\n\n \left \{ {{y=13} \atop {x=7}} \right.$

3D+14G=203(11) use elimination 33D+154G=2233
11D+11G=220(-14) to cancel G -154D-154G=-3080

-121D=-847 divide by -121 on both sides
D=7 plug back into equation
11(7)+11G=220
77+11G=220 subtract 77 from both sides
11G=143 divide by 11 on both sides
G=13

A doctor estimates that a particular patient is losing bone density at a rate of 3% annually. The patient currently has a bone density of 1,500 kg/mg3. The doctor writers an exponential function to represent the situation. Which values should the doctor use of a and b in a function written in the form f(x)= abx, where f(x) represents the bone density after x years?

Answers

If a patient is losing bone density at the rate of 3 % annually then it will rest:
100% - 3% = 97 %, or 0.97 of a bone density.
The doctor should use a function: $f(x)= 1,500 * 0.97^(x)$
a = 1,500, b = 0.97
