After graphing the lines, the answer is (-3/4, 31/4)
Answer: PN= 20 in.
Step-by-step explanation:
Given: In triangles PMN and QSR :
Length of P N ≅ Length of RQ (1) [ '≅' → Sign of congruence]
Length of QS ≅ Length of PM
Length of MN ≅ Length of RS
By SSS congruence rule
ΔPMN ≅ ΔQSR
Since Length of QR =20 in. [Given]
From (1)
Length of PN= 20 in. [Congruent means exactly equal]
Answer:
<u>Volume=2.2*10^10 km^3
</u>
Step-by-step explanation:
Given
Diameter of moon=d=3476 km
The formula for the volume of sphere is:
V=4/3 πr^3
As it can be clearly seen that the formula uses radius, and we are given diameter. So we have to find the radius first
So,
radius=r=d/2
=3476/2
=1738 km
Now putting the value of r and pi in the formula:
V=4/3*3.14*(1738)^3
=12.56/3* 5249879272
= 21979494552.106
Rounded off to two significant digits:
<u>Volume=2.2*10^10 km^3
</u>
Answer:
the value of 2 in 0.812 is 2 thousandths/0.002
0.002 = 2/1000
0.812 = 812/1000
I f i am correct 15 and 16
cuz 15+16 = 31
but 16-15= 1
