Show ur work will give braniest

Andrews [41]

I think this is a trick question. That’s because 5.61 is the width, 2.3 is the thickness, and 13.672 is the length. If they are cutting it into 3 strips, wouldn’t you just multiply 13.672 by 3 to get 41.016? That would be the total length right?

The points -5,2 and -5,8 lie on a circle with a radius of 3. Find the center of the circle.

worty [1.4K]

The formula of a distance between two points:

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

We have two points A(-5, 2) and B(-5, 8). Substitute:

$d=\sqrt{(8-2)^2+(-5-(-5))^2}=\sqrt{6^2+0^2}=\sqrt{6^2}=6$

d is a diameter of a circle because d = 2r = 2(3).

The center of a circle is in midpoint of AB.

The formula of a midpoint:

$M\left(\dfrac{x_1+x_2}{2},\ \dfrac{y_1+y_2}{2}\right)$

Substitute:

$\dfrac{-5+(-5)}{2}=\dfrac{-10}{2}=-5\\\\\dfrac{2+8}{2}=\dfrac{10}{2}=5$

Answer: (-5, 5).

If a condominium is purchased for Php 5,700,000.00 and the bank requires 30% down payment, how much is the mortgaged amount?

Darya [45]

We are given that the condominium cost Php 5,700,000.00 and a down payment was made. Since the down payment was 30% of the total cost, therefore we can conclude that the mortgage amount is 70% of the total cost. Hence:

70% = 0.70

mortgage amount = 5,700,000.00 * 0.70

mortgage amount = 3,990,000.00

What is the value of this expression when a = 4, b = -5, and c = -7?

Ganezh [65]

Answer:

The value of the given expression is -878.08.

Step-by-step explanation:

Here, the given question is INCOMPLETE.

The complete question is:

Evaluate the expression for a = 4, b = -5, and c = -7. $4a^2b^{-2}c^3$

Here, substitute the vale of a = 4, b = -5 and c = -7, we get:

$4a^2b^{-2}c^3 = (\frac{4a^2c^3}{b^2}) = (\frac{4(4)^2(-7)^3}{(-5)^2})\\= (\frac{64 \times 343}{25}) =\frac{21,952}{25} = 878.08\\\implies 4a^2b^{-2}c^3 = 878.08 ( a = 4, b = -5 ,c = -7)$

Hence, the value of the given expression is -878.08.
