Answer:
22
Step-by-step explanation:
11 x 2 = 22
24 pencils = 100%
30 pencils = ___%
30 - 24 = 6, so:
24 / 6 = 4 (it means that there are 4 sixes in 100%)
100% / 4 = 25%
Check: 25% * 24 = 25/100 * 24 = 1/4 * 24 = 6
30 - 6 = 24 (correct)
Answer: There was an increase by 25%
20 miles = 100%
11 miles = ___%
1 mile = 100% / 20 = 5%, so:
5 * 11 = 55 [percent]
100% - 55% = 45%
Check: 45% * 20 = 45/100 * 20 = 45/10 * 2 = 9/2 * 2 = 9
20 - 9 = 11 (correct)
Abswer: There was a decrease by 45%
V=4/3 π•r^3
r=6.9 ft
V=4/3 π• (6.9)^3
V=4/3 π • 328.509 ft^3
V= π•438.012 ft^3
V= 1,375.35768 ft^3
V~ 1,375 ft^3
Answer:
$2278.50
Step-by-step explanation:
We know that
<span>Object A is 1.3 cm long-------------> 1.3*10-------> 13 mm long
</span><span>Object B is 130 mm long
then
</span>Object B is 10 times longer than Object A
Statement
<span>1) The lengths are equal.--------> is false
Object B > Object A
2) Object B is 10 times longer than object A. -------> is true
</span>Object B=10*Object A
<span>
3)Both measurements are less than 1 meter.-------> is true
1 m---------> 1000 mm
</span>Object B (130 mm) < 1000 mm
Object A (13 mm) < 1000 mm
<span>
4)You can convert millimeters to centimeters by dividing by 100------> is false
</span>You can convert millimeters to centimeters by dividing by 10
therefore
the statement that are true
1) <span>Object B is 10 times longer than object A
2) </span>Both measurements are less than 1 meter
