The correct answer among all the other choices is D. both (a) and (b). The statements that are always true of similar polygons are corresponding angles of similar figures have the same measure and the lengths of corresponding sides form equivalent ratios. Thank you for posting your question. I hope this answer helped you. Let me know if you need more help.
Answer:
a). V
= 14.6208 litres : b). = 0.29844 Litres/sec
Step-by-step explanation:
a).
Step 1.
Volume when one half of rod is inserted = (50/2)*(2.2) = 55cm³
Step 2.
As we know that,
V = (ρV
IΔT)
/ (ρL
)
where = 290 - 4.2 = 285.8K
sepecififc heat of aluminum = 0.215 cal/g
density = 2.7 g/cm3
= (2.7)*(55)*(0.215)*(285.8) / (0.125)*(20900)*(1/4186)
V = 14.6208 litres
b).
Step 1.
As we know that
P = kA(dT/dx) = 31*2.2*[(290-4.2)/25]
= 779.6624 W
Step 2.
Now, approximate boil rate of helium is:
P/ρL= [(779.6624)*(10^3g/kg)] / [(0.125)*(20900)]
= 0.29844 Litres/sec
Answer:
x is greater than or equal to -5 (the second graph)

Answer:
a. 2^3
b. 3^4
c. 4^3 × 5^2
d. 9^4 × 7^2
Step-by-step explanation:
The following equations are given
a. 2 × 2× 2
b. 3 × 3 × 3 × 3
c. 4 × 4 × 4 × 5 × 5
d. 9 × 7 × 9 × 9 × 7 × 9
We need to find the index notation for the above equations
a. 2^3
b. 3^4
c. 4^3 × 5^2
d. 9^4 × 7^2
In this way it should be done
The same would be relevant
Answer:
NO
Step-by-step explanation: no because Lauren will receive 26 because 10 = (8 x 2) which equals 26 and Migule is 20 + ( 1 x 10) which = 30 so not the same this and simple and cute reason hope it right and helped.
