Answer:
Decimal: 0.23
Fraction: 23/100
Percent: 23%
Step-by-step explanation:
In this case, one whole is 100. This is because there are 100 little squares in the one big square.
The amount of shaded squares is 23.
This can be represented as the fraction 23/100. 23/100 is the same as 23 being divided by 100. 23 divided by 100 is 0.23 (our decimal). To find a percent, move the decimal point to the right 2 times. Our percent is 23%.
Answer: C) 19%
Step-by-step explanation:250 +200 + 150 + 125 + 50 = 775 total complaints. 150 rude sales clerks out of 775 total complaints equals 150/775 = 0.1935 which is a 19 percent. So 19 percent of the complaints are about rude sales clerks.
Answer:
168 Beats per minute
Step-by-step explanation:
42/1/4 = 168
Formula for V of pyramid is V = 1/3 Bh
B = area of base
h = height
Q1.
8 x 6 = 48
48 = area of base
48 x 5 (height) = 240
240 x 1/3 = 80
80 cm^3
Q2.
8 x 12 would get the area of the base.
the formula says 1/3 Bh, so the base is multiplied by the height (10) and by 1/3.
So if you substitute in the values into the formula, it'll be:
V = 1/3 (12) (8) (10)
Q3.
4 x 6 = 24
base = 24 cm^2
height = 9
1/3 x 24 x 9 = 72
Volume = 72 cm^3
statement 1 is incorrect. The area of the base is actually 24 cm^2
statement 2 is correct.
statement 3 is correct. the volume of the rectangular prism (9 x 4 x 6) is 216cm^3, which is 3 times the volume of the pyramid (72 cm^3).
statement 4 is incorrect. This would require the volume of the pyramid to be 9 times of its own volume.
statement 5 is correct.
statement 6 is incorrect. The volume of the pyramid is 72, not 216.
Q4.
use the balance method to get the answer.
108 / 1/3 = 108 x 3 = 324
324 / 9 (the height) = 36
the base has an area of 36 in^2
Q5.
6 x 4 gets the area of the base
8 is the height
substitute them into the formula:
V = 1/3 (6) (4) (8)
Q6.
8 x 6 = 48
48 = area of base
9 = height
substitute them into the formula:
V = 1/3 (48) (9)
1/3 x 48 x 9 = 144
Volume of this pyramid is 144 in^3
