third: 1/2
Step-by-step explanation:
Answer:
PS = 28 units.
Step-by-step explanation:
See the attached diagram.
This is a figure of rectangle with length (3y + 3) and width 4y.
Now, the perimeter of the rectangle is 2[(3y + 3) + 4y] = 2(7y + 3)
The perimeter of the rectangle is given to be 104 units.
So, 2(7y + 3) = 104
⇒ 7y + 3 = 52
⇒ 7y = 49
⇒ y = 7
Therefore, PS = 4y = 4(7) = 28 units. (Answer)
Answer:
90
Step-by-step explanation:
Given that :
Number of soldiers = 8160
Number left out = 60
Result of arrangement gives a perfect square ;
Hence, the number of soldiers which makes up the arrangement will be ;
Total number of soldiers - number left out
8160 - 60 = 8100
Hence 8100 soldiers were used to form a perfect square ;
Number of soldiers in a row :
√8100 = 90
Hence, we have 90 soldiers in a row
Answer:
53,775J
Step-by-step explanation:
KE = ½ mv2
KE = ?
m = 478kg
v = 15m/s
KE = ½ (478kg) (15 m/s)2
KE = ½ (478kg)(225)
KE = 53,775J
mark me brainlest plz
When you have an exponent divided by another exponent, you subtract the exponents (only when it has the same base)
For example:
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive
For example:
1. 
2. 
3. 
4. 
5. 
This is one of the ways you could have done it
6. 
7. 
Divide 63 and 9
8.

If you multiply an exponent directly with another exponent, you multiply the exponents together
For example:
If you multiply a variable with an exponent by a variable with an exponent, you add the exponents
For example:
