Describe the nature of the roots for the equation
49x2– 28x +4 = 0

Answers

Answer 1

Answer:

The roots of the equation is real and repeated

Step-by-step explanation:

Here, we want to describe the nature of the roots of the given quadratic equation

To get the nature of the roots, we find the discriminant of the equation

The discriminant is;

b^2 - 4ac

In this case, b = -28 , a = 49 and c = 4

The discriminant is thus;

-28^2 - 4(49)(4)

= 784 - 784 = 0

Since the discriminant is zero, this means that the quadratic equation has real roots which are the same

A package of nuts weights 3/4 of a pound. One serving size is 1/8 of a pound, how many servings in the package?

Answers

Answer: 6 servings

Step-by-step explanation:

One serving is 1/8 of a pound.

One package is 3/4 of a pound.

The number of servings therefore will be the number of times that 1/8 can go into 3/4.

= (3/4) / (1/8)

= (3/4) * (8/1)

= 6 servings

Trisha’s parents bought a new house that has 2,255 square feet.
The price per square foot was $98. How much did they pay for the house? Enter your answer in the box.

Answers

Answer:$220,290

Step-by-step explanation:

2,255 multiplied by 98 is 220,290

The total cost of Trisha’s parents new house is $220990.

Given that, Trisha’s parents bought a new house that has 2,255 square feet.

What is the unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

The price per square foot was $98.

So, the total cost of house = Number of square feet × The price per square foot

= 2,255 × 98

= $220990

Therefore, the total cost of Trisha’s parents new house is $220990.

Ronnie made 5 pies for New Year's Day. Some of his family members are allergic to gluten, so he bought gluten-free flour for all of the pies. For each piecrust, he used 2 cups of flour. Health Mart sold bags with 4 cups of gluten-free flour for $12. How much did Ronnie spend on the gluten-free flour so that he had enough for the crusts?

Answers

Answer:

He spent $24 dollars

Step-by-step explanation:

Each of the piecrusts had 2 cup of flour he has 5 pies so all pies altogether equally 10 cups so he buys 2 bags for $24 dollars

Step-by-step explanation:

Number of gluten-free flour used for 5 pies= 2×5= 10 cups

cost of 4 cups of gluten-free flour = $12

cost of 1 cup = 12/4 = $3

Then,

cost of 10 cups of gluten-free flour = 3×10

= $30

There is a common difference d between consecutive terms, that is

A recursive rule allows a term to be found by adding d to the previous term, thus
