At present Asha's age (in years) is two more than the square of her daughter Nisha's age (in years). When Nisha grows to her mother's present age, Asha's age would be one year less than 10 times the present age of Nisha. Find the present age of Asha and Nisha

Answers

Answer 1

Answer:

Answer:

Asha's present age is 27 years and Nisha's present age is 5 years.

Step-by-step explanation:

Let the present age of Nisha be $x$ years.

As per question, Asha's present age is 2 more than the square of Nisha's age.

$\therefore$ Asha's present age = $x^2+2$

Now, Nisha will reach her mother's age after $x^2+2-x$ years.

Therefore, age of Asha after $x^2+2-x$ years will be = $x^2+2+x^2+2-x=2x^2-x+4$

Now, as per question,

$2x^2-x+4=10x-1\n2x^2-x-10x+4+1=0\n2x^2-11x+5=0\n2x^2-x-10x+5=0\nx(2x-1)-5(2x-1)=0\n(2x-1)(x-5)=0\nx=(1)/(2)\ or\ x=5$

As age can't be in fraction, we consider the present age of Nisha as 5 years. So, Asha's present age is $x^2+2=5^2+2=25+2=27$ years.

Therefore, Asha's present age is 27 years and Nisha's present age is 5 years.

Help please?Describe a situation that matches the equation. 34 = g + 25

B: The eighth-grade class has 34 students. The year before, when the students were in seventh grade, there were 25 students. How many students were added between seventh and eighth grade?

C: A person bikes 34 miles on Monday and 25 miles on Tuesday. How many miles total did the person bike?

D: Jack has 25 marbles. Mary gives him 34 marbles. How many marbles does Jack have?

Answers

Answer:

Option B matches the equation

Step-by-step explanation:

Equation: 34 = g + 25

A:Since we are given that The temperature on Monday was 25 degrees below zero So, in given equation there should be -25 in place of 25

So, It does not matches the equation

B: The year before, when the students were in seventh grade, there were 25 students.

Let g be the no. of students added between seventh and eighth grade

So, Total students = 25+g

We are given that The eighth-grade class has 34 students.

So, equation becomes : 34=g+25

It matches the equation.

C :A person bikes 34 miles on Monday

He bikes 25 miles on Tuesday.

So, Total miles =25+34

So, It does not matches the equation

D: Jack has 25 marbles.

Mary gives him 34 marbles.

Total marbles = 25+34

So, It does not matches the equation

Hence Option B matches the equation

Answer:

The answer is B!

Step-by-step explanation:

The equation and the equation from scenario B are both, when simplified, g = 9.

Okay here is the math problem..Ivana has 3/4 lbs of hamburger meat. she makes 3 hamburger patties. Each patty weighs the same amount. How much does each hamburger patty weigh?

Answers

Answer:

$Weigh\ of\ each\ hamburger\ patty\ is (1)/(4)\ lbs$

Step-by-step explanation:

As given

$Ivana\ has\ (3)/(4)\ lbs\ of\ hamburger\ meat.$

she makes 3 hamburger patties.

Each patty weighs the same amount.

Thus

$Weigh\ of\ each\ hamburger\ patty = (Total\ amount\ of\ hamburger\ meat)/(Total\ number\ of\ hamburger)$

Putting the values in the above

$Weigh\ of\ each\ hamburger\ patty = ((3)/(4))/(3)$

$Weigh\ of\ each\ hamburger\ patty = (1)/(4)\ lbs$

$Therefore\ weigh\ of\ each\ hamburger\ patty\ is (1)/(4)\ lbs$

Each hamburger weighs 1/4 lbs.

Which fraction is greater between 3/8 2/8 312-6512

Answers

Answer:

Step-by-step explanation:

3/8

Final answer:

Among 3/8 and 2/8, the fraction 3/8 is greater because 3 is a larger number than 2. The part '312-6512' doesn't seem relevant to the problem, so it's likely a typo.

Explanation:

To figure out which fraction is greater between 3/8 and 2/8, we need to compare these two numbers. Since they both have the same denominator (the number on the bottom), you can compare them easily by simply looking at the numerator (the number on the top).

Here, 3 is bigger than 2. Thus, 3/8 is the larger fraction compared to 2/8.

The part of the question which says '312-6512' doesn't seem to relate to the problem, thus we ignore it as a typo.
