Answer:

\$21.1

Step-by-step explanation:

We know that for principal amount P , time period T and rate of interest R\% , simple interest is given by S.I. = \frac{P\times R\times T}{100} .

Here ,

P=\$1600\\T=2\,\,months=\frac{2}{12}\,\,years=\frac{1}{6}\,\,years\\S.I=\$56.24

To find :  simple interest rate i.e., R\%

On putting values of P\,,\,T\,,\,S.I in formula , we get S.I. = \frac{P\times R\times T}{100}

56.24 = \frac{1600\times R\times 1}{600}\\R=\frac{56.24\times 600 }{1600}=\frac{703\times 3}{100}=\$21.09

Now we need to round off the answer to the nearest tenth .

So, simple interest rate is % = \$21.09 = \$21.1

Lean wants to giftwrap a present she got for her little brother. how many square inches of giftwrap will be needed to cover a bo
Natalka [10]
Check the picture below.

so.. notice, the box for the gift is really just a rectangular prism, which is really just 6 rectangles stacked up to each other at the edges.

the front and back are two 5x3 rectangles

the left and right are just two 3x7 rectangles

and the top and bottom are just two 5x7 rectangles

so, just get the area of each, sum them up, and that's the area of the rectangular prism and thus of the box, and that's how many in² she will need.

How do I get the answer y= 2x^2+9x-5

Answer:

Quadratic Formula

so

x = -5

and

x = 0.5

Step-by-step explanation:

Whenever you see a problem in this form, which you will see a lot of, you can try to factor it or use the "least squares" method or what have you, but those won't always work, unfortunately.

Fortunately, the quadratic formula will never fail you with quadratic expressions.

This is the Quadratic Formula

x = \frac{-b \frac{+}{-} \sqrt{b^2-4ac}  }{2a}

a is the the number on the variable with the exponent ^2

b is the number on the variable with no exponent

c is the third number

a and b cannot be equal to 0; c can be

Since we're looking for a number with an equation that has a square root in it, we're going to get two answers. These two answers come from the radical being separately added AND subtracted from the radical. It's basically two problems.

Plugging  in our numbers to this equation gives us x values of -5 and 0.5. This will always work with polynomials with factors of ^2 in them.

If you have a TI-84 calculator or newer, there's a tool on it that will factor polynomials like this one for you just by giving it the numbers.
