Answer:
1. 39 km/hr
2. $235
3. 16
4. 7m+3 inches
Step-by-step explanation:
1. Original speed of car: x km
x+21=60
x=39
original speed: 39 km/hr
2. Amount that the freshman class raised: x
2x+85=555
2x=555-85=470
x=235
Amount that the freshman class raised: $235
3. Number: x
5x-9=71
5x=71+9=80
x=16
The number: 16
4.
3m+5+4m-2
= 3m+4m+5-2
=7m+3 inches
Answer:
+5.20 µC
Explanation:
Given that
Charge =−5.20 µC and radius= 5.40 cm.
Insert a +10.4- µC charge at the center of the sphere
As we know that according to Gauss's theorem electric field inside the metal is zero.
When +10.4 µC charge insert but the total charge on the sphere should be −5.20 µC.So the charge on the outer surface of the sphere will be +5.20 µC.
Determine the ratio of defective telephones
ratio = 9/30
ratio = 3/10
3 of 10 telephones are defective
Determine the number of defective telephones each day
def telephone = ratio of defective × total production
def telephone = 3/10 × 1000
def telephone = 300
There are 300 defective telephones each day
4/8 and 3/6. Both of these z= 1/2
