C and D
the volume ( V) of a pyramid is found using the formula
V = 
× area of base × height
calculating each of the volumes gives
(A) V = × 10.5 × 6 = 21 in³
(B) V = × 3.6 × 8 = 9.6 in³
(C) V = × 4.2 × 12 = 16,8 in³
(D) V = × 6 × 8.4 = 16.8 in³
C and D have equal volumes
Answer:
105 cm
Step-by-step explanation:
Table + cat - mouse = 120 ...(1)
table + mouse - cat = 90 ...(2)
(1)+(2): 2*Table = 210
Table = 105
2:3 ration when you simplify it out.
Answer:
The correct answer is 300 breaths in 2 minutes.
Step-by-step explanation:
4b/10s
First find out the initial breath per second.
10/4 = 2.5b
Then how many seconds is in 2 minutes.
120 seconds in two minutes.
Then multiply the seconds by the breaths per second.
2.5b * 120s = 300b
Liliana takes 300 breaths in 2 minutes
Answer:
-√(1 - 2x) + C
Step-by-step explanation:
1/√(1-2x)
We want to integrate it. Thus;
∫1/√(1 - 2x) dx
Let u = 1 - 2x
Thus;
du/dx = -2
Thus, dx = -½du
Thus,we now have;
-½∫1/√(u) du
By application of power rule, we will now have;
-½∫1/√(u) du = -√(u) + C
Plugging in the value of u, we will have;
-√(1 - 2x) + C
