Answer:
27 units (whatever units the figure was measured in)
Step-by-step explanation:
Volume is length times width times height. So, you would need to do 9 times 3 (27) times 10 (270). Then, you would divide by 10, because it is scaled down by 1/10, leaving you with 27.
Answer:
D) Both A and C are correct.
Step-by-step explanation:
If the sample contains 50 students, the percentage equivalent to each student is:
Each student corresponds to 2%, which means that percentages should be multiples of 2%.
21% is not a multiple of 2% and corresponds to:
21% of 50 students is 10.5 students, and you cannot sample a fraction of a student.
Therefore, Both A and C are correct.
Side x side=area of a square
s^2=169
s= square root of 169
s=13
D.
Hope this helps.
Answer:
52%
Step-by-step explanation:
13/25
13 ÷ 25
0.52
0.52 × 100/100
0.52 × 100%
(0.52 × 100)%
52%
Answer: 1,162.9 cm3
Step-by-step explanation:
Hi, to answer this question we have to apply the next formula:
Volume of a square pyramid: 1/3 x base area x height
Where
base area = base side length ^2
Replacing with the value given:
Base area = 15.9^2
base area : 252.81 cm2
Back with the volume formula:
V = 1/3 x base area x height
Replacing with the values given and solving for V (volume)
V = 1/3 x 252.81 x 13.8 = 1,162.9 cubic centimeters
