Answer:
3 packages
Step-by-step explanation:
There are 1000 m in 1 km, so 2500 m is the same as 2.5 km.
1 package = 2.5 km
2 packages = 5.0 km . . . . still too little
3 packages = 7.5 km . . . . more than sufficient
Annabelle needs 3 packages of yarn to satisfy her requirement for 7 km.
Answer:
5x+6 =-4
x = -2
Step-by-step explanation:
product of 5 and a number x
5x
six more than
5x+6
is means equal
5x+6 =-4
Subtract 6 from each side
5x+6-6 = -4-6
5x= -10
Divide by 5
5x/5 = -10/5
x= -2

Answer:
The intensity of the 2011 earthquake was about 6 times the intensity of the 2003 earthquake.
Step-by-step explanation:
To compare the intensities, we first need to convert the magnitudes to intensities using the log formula. Then we will set up a ratio to compare the intensities.
Convert the magnitudes to intensities and write them in exponential form.
R=logI
2011 earthquake:
9.1I=logI=109.1
2003 earthquake:
8.3I=logI=108.3
Form a ratio of the intensities.
intensity for 2011intensity for 2003
Substitute in the values and divide by subtracting the exponents to find
109.1108.3100.8≈6.
The intensity of the 2011 earthquake was about 6 times the intensity of the 2003 earthquake.
Your answer:
The intensity of the 2011 earthquake was about 15 times the intensity of the 2003 earthquake.
