3.

1 answer:

5 0

Correct Answer: Option A

Principal Amount = P = $23,400
Interest rate = r = 3% = 0.03
Time = t = 10
Number of compounding periods in a year = n = 2
Compounded amount = A = ?

Formula for compound interest is:

$A = P(1+ \frac{r}{n} )^{t*n}$

Using the values, we get:

$A=23400(1+ \frac{0.03}{2})^{2*10}=31516.41$

Option A is the closest one, so its the correct answer

What is the unit ratio for a button of 16 grams and 2 milliliters?

Reika [66]

Answer:

The unit ratio would be 8 grams per milliliters

Step-by-step explanation:

Since, the unit ratio is a fraction with denominator 1,

In other words, the amount of one quantity in unit amount of other quantity is called unit rate or unit ratio.

Here, the amount first quantity = 16 grams,

The amount of second quantity = 2 milliliters,

Thus, unit ratio = $\frac{\text{First quantity}}{\text{Second quantity }}$

$=\frac{16}{2}$ = 8 grams per milliliters

Find the difference when the polynomial -5x^2+3x+8 is subtracted from the polynomial 2x^2+4x+1.

geniusboy [140]

The difference is $7x^{2} + 1x-7$ .

Step-by-step explanation:

Step 1:

The polynomial $-5x^{2}+3x+8$ is subtracted from the polynomial $2x^{2} + 4x +1$ .

If we write this as an equation, we get

$(2x^{2} + 4x +1) -(-5x^{2}+3x+8)$ .

To subtract the polynomials, we group up the terms based on their variables.

In this subtraction, there are two variables i.e. $x^{2}$ and $x$ and there is one constant term.

Step 2:

The subtraction of the $x^{2}$ variables; $2x^{2} -(-5x^{2} ) = 2x^{2} +5x^{2} = 7x^{2}$ .

The subtraction of the $x$ variables; $4x - (3x) = 1x$ .

The subtraction of the constants; $1-(8) = -7$ .

So $(2x^{2} + 4x +1) -(-5x^{2}+3x+8) = 7x^{2} + 1x-7$ .

Help please posted picture of question

bagirrra123 [75]

The given equation is:

y = -10x + 1
Slope of this equation = -10

New line will be perpendicular to this line, so slope of new line = 1/10

So, we are to find the equation of a line with slope 1/10 and passing through (5,7). Using the point slope form we can write

y - 7 = 1/10 ( x - 5)
y = x/10 -1/2 + 7
y = x/10 + 13/2
⇒
x/10 - y = -13/2

So option C gives the correct equation of the new line

grin007 [14]

<span>The question is asking us to determine the length of the floor of a rectangular deck. The rectangular deck has an area of 600 squared feet. The floor is 20 feet wide ( W = 20 ft ). Formula for the area of the rectangle is: A = L x W. 600 = L X 20; L = 600 : 20; L = 30 ft. Answer: The floor is 30 ft long.</span>
