Answer:

64 degree and 116 degree

Step-by-step explanation:

4y-44+3y+35=180(Linear pair)

7y=189

y=27

4(27)-44=64

3(27)+35=116

Given the height, h, and the volume v of a certain cylinder, alex uses the formula v ph r 5 !§ to compute its radius, r, to be 1

dmitriy555 [2]

We know that
volume of a cylinder=pi*r²*h
r=√[V/(pi*h)]
r=10 m

A second cylinder has
V2=V-----> volume of the second cylinder
h2=25*h----> height of the second cylinder
r2----> radius of the second cylinder
r2=√[V2/(pi*h2)]----> r2=√[V/(pi*25*h)]---> r2=(1/5)*√[V/(pi*h)

r2=(1/5)*10-----> r2=2 m

the answer is
the radius of the second cylinder is 2 m

What is the gravity of a location if the mass of an object is 300 kg and it has a weight of 450N ?

kozerog [31]

The gravity is 1.5m\s^2

Further explanation:

The weight of any object is given by the product of mass and gravity of the object

Let

m denote the mass of object

g be the gravity

and

w be the weight

Then the statement can be mathematically written as:

$w=m*g$

Given

m=300kg

w=450N

Putting the values of m and w into the formula

$450=g*300\\g= \frac{450}{300}\\g=1.5\ ms^{-2}$

The gravity is 1.5m\s^2
