Rasek [7]

Answer:

$x=2\sqrt3\ km$

Step-by-step explanation:

Given that,

The base of a triangle = 2 km

The perpendicular height of the triangle = $2\sqrt{2} \ km$

We need to find the value of x. It is the Hypotenuse of the triangle. It can be solved as :

$x=\sqrt{(2\sqrt{2})^2+2^2 } \\\\=2\sqrt{2+1 } \\\\=2\sqrt3\ km$

So, the value of x is equal to $2\sqrt3\ km$ .

Enter the value of p so the expression 5/6-1/3nis equivalent to p(5-2n).

SIZIF [17.4K]

Take LCD of 6 and 3 = 6 is the lcm
5/6 -2/6n
(5-2n)/6.

Now, what number can be multiplied to the right side of the equal sign to get the value of P

The answer is 1/6 as the left side is divided by 6, so multiply the right side by 1/6 to make it equivalent.

Araceli uses 9.6 pints of blue paint and white paint to paint her bedroom walls. Three fourths of this amount is blue paint , an

Soloha48 [4]

Answer:

2.4 pints

Step-by-step explanation:

Araceli uses 9.6 pints of blue paint and white paints, that means the total volume of paint is 9.6 pints

If Three fourths of this amount is blue paint ,

Then $\frac{3}{4} X 9.6=7.2 pints$

7.2 pints of blue paint was used.

We want to find out how much white paint was used by Araceli

Volume of Blue Paint+Volume of White Paint=Total Volume of Paint

7.2+Volume of White Paint=9.6

Volume of White Paint=9.6-7.2=2.4 pints
