Answer: A) Acute

Step-by-step explanation:

Compare the sum of the squares of the two smaller numbers (a² + b²) to the square of the largest number (c²).

If a² + b² > c², then the triangle is Acute

If a² + b² = c², then the triangle is Right

If a² + b² < c², then the triangle is Obtuse

65² + 72² ____ 96²

4225 + 5184 ____ 9216

9409 > 9216 So, the triangle is Acute.

.The endpoints of AB are A(1,4) and B(6,-1).

Brums [2.3K]

Answer:

5√2

Step-by-step explanation:

Finding distance :-

d = √{ ( 1 -6)² + (4+1)²}
d = √{ -5² + 5² }
d = √{ 25 + 25}
d = √50
d = 5√2

A rectangular box has length 20cm, width 6cm and height 4cm. find how many cubes of size 2cm that will fit into the box.

Papessa [141]

Answer:

$\boxed{\pink{\sf The \ number \ of \ cubes \ that \ can \ be \ fitted \ is 60 .}}$

Step-by-step explanation:

Given dimensions of the box = 20cm × 6cm × 4cm .

Dimension of the cube = 2cm × 2cm × 2cm .

Therefore the number of cubes that can be fitted into the box will be equal to the Volume of box divided by the Volume of the cube. So ,

$\boxed{\red{\bf \implies No. \ of \ cubes \ = \dfrac{Volume \ of \ box}{Volume \ of \ cube }}}$

$\bf \implies n_{cubes} = \dfrac{20cm \times 6cm \times 4cm .}{2cm \times 2cm \times 2cm } \\\\\bf\implies n_{cubes} = 10 \ times 3cm \times 2cm \\\\\implies \boxed{\bf n_{cubes}= 60 }$

<h3>Hence the number of cubes that can be fitted in the box is 60 .</h3>

3. The formula to find the surface area of a sphere is to take the radius of the sphere and square it and multiply that amount b

KatRina [158]

The way to get the equation for the radius (r) is to get r by itself. So divide each side by 4pi
500/4pi=r^2
Now take the square root of each side to get the equation of r.
sqrt(500/4pi)=r
