Marco borrowed $150 from his brother. He had paid back 30% so far. How much money does Marco still owe his brother?

worty [1.4K]

Answer:

He still owes $105

Step-by-step explanation:

First, we have to find how much money Marco had paid back.

We are going to find the percentage of the number:

$\frac{150 * 30}{100} = 45$

Then, doing a simple mathematical subtraction we can find how much money he still owes to his brother:

$150 - 45 = 105$

Find the midpoint of the line segment with end coordinates of: <br> (-2,-4) and (-1,-5)

Deffense [45]

$\qquad\qquad\huge\underline{{\sf Answer}}♨$

Let's use section formula ~

$\qquad \sf \dashrightarrow \:x = \dfrac{mx_2 + nx_1}{m + n}$

$\qquad \sf \dashrightarrow \:y = \dfrac{my_2 + ny_1}{m + n}$

And since mid point divides a line segment Into two equal parts, m : n = 1 : 1

so, take m = n = 1

$\qquad \sf \dashrightarrow \:x = \dfrac{(1 \times - 1)+(1 \times - 2)}{ 1+ 1}$

$\qquad \sf \dashrightarrow \:x = \dfrac{- 1- 2}{ 2}$

$\qquad \sf \dashrightarrow \:x = \dfrac{ - 3}{ 2}$

Now, let's find y - coordinate ~

$\qquad \sf \dashrightarrow \:y = \dfrac{(1 \times - 5) + (1 \times - 4)}{1 + 1}$

$\qquad \sf \dashrightarrow \:y = \dfrac{ - 5 - 4}{2}$

$\qquad \sf \dashrightarrow \:y = \dfrac{ - 9}{2}$

So, coordinates of midpoint is ~

$\qquad \sf \dashrightarrow \:( - \dfrac{3}{2} ,- \dfrac{9}{2} )$

Factor the trinomial below.<br>4x2 + 12x +9

Aleks [24]

The factor of the trinomial is $(2x+3)^2$

Explanation:

The given trinomial is $4x^{2} +12x+9$

We need to determine the factor of the trinomial.

The factor of the trinomial can be determined by finding the root of the trinomial.

Let us factorize the trinomial $4x^{2} +12x+9$

Thus, the trinomial can be written as,

$4x^{2} +6x+6x+9$

Grouping the terms, we have,

$2x(2x +3)+3(2x+3)$

Simplifying the terms, we get,

$(2x+3)(2x+3)$

Multiplying the terms, we have,

$(2x+3)^2$

Thus, the factor of the trinomial is $(2x+3)^2$
