Answer:

<h3>The answer is </h3><h3 /><h3>1125 Kg</h3>

Step-by-step explanation:

To find the mass in kg we must first convert the density from g/cm³ to kg/m³

That's 7.5 g/cm³ = 7500kg/m³

Density = mass / volume

Volume of block = 1.5 × 0.4 × 0.25

= 0.15m³

mass = Density × volume

= 7500 × 0.15

<h3>= 1125 Kg</h3>

Hope this helps you

What is the equation of the circle with center (16, - 12) and a radius of 5
eimsori [14]

Answer:

x^2+y^2-32x+24y+375=0

Step-by-step explanation:

Equation of circle with given centre (h,k) and radius=r is

(x-h)^2+(y-k)^2=r^2

Given centre are=(16, - 12) and radius= 5

So equation of circle=

(x-16)^2+(y- -12)^2=5^2

x^2-32x+256+y^2+24y+144=25

x^2+y^2-32x+24y+375=0

A(n) ______ is the common side of two consecutive angles in a polygon.2.A statement you can probe and then use as a reason in la
Nikolay [14]
An ??????


Well to figure this out, we will use mathematics. You do 90% of the an and then do 39 which is close to 90 and then because it has 9 in the number that is given. So, 213 is incorrect. 90% of the things like 213, = 39. And if it equals 39, then here comes 90. 90 comes in as a number to help, but 213 does to. So we will divide the number 9. 9 = 2, and since 213 has the first digit 2 in the number, that means that the answer is An number that equals 2 is the common side of two consecutive angles in a polygon.

Find the slope of the given line, if it is defined. 2x + 1 = 0
svlad2 [7]

Given :

A line 2x + 1 =0 .

To Find :

The slope of the given line .

Solution :

We know , slope of line is given by the tangent of the angle between the x-axis and the line .

Now, for line 2x + 1 =0 i.e x=\dfrac{-1}{2} .

The line is perpendicular to x-axis and cuts the x-axis at \dfrac{-1}{2} .

Therefore , the angle between the line and x-axis is 90^o .

So , slope m=\tan\ 90^o i.e undefined .

Therefore , the slope of given line is not defined .

Hence , this is the required solution .
