Answer:
the volume is 50x1.8x2
v=180cm³
therefore, density is mass/volume
Step-by-step explanation:
mass =density x volume
mass= 7.8 x 180cm³
mass= 1,404grams
Answer:
-5.5°C > -17.5°C
Step-by-step explanation:
Since -5.5 is larger than -17.5
Answer and Explanation:
Volume of a cylinder is given by
V= Pi*r²*h
where v= volume of the cylinder
Pi is constant = 22/7 or 3.14159
r= radius of the circle of the cylinder
h= height of the cylinder
If two cylinders are measured proportionally to the other based on radius and height of each cylinder, we look at the proportional equality of the ratio of the radius and height of one cylinder to the other. If one cylinder for example has ratio of radius and height =2/4 then it is proportional to the other cylinder with ratio 1/2
Answer:
Step-by-step explanation:
L and W are the length and width of the garden, respectively.
perimeter = 2L+2W = 38 ft
L+W = 19
the length is 5 ft longer than the width
L = W+5
substitution
(W+5)+W = 19
2W+5 = 19
W = 7
Answer:
Step-by-step explanation:
We want to find the sum of all even numbers from 0 to 175.
The series will be:
The explicit formula for this is 
, where 
.
We need to find how many terms are there.
The sum of terms is given by:
Substitute n=88, 
and l=174 to get:
