Answer:
answer = 7.5
Step-by-step explanation:
PG = 2 PR ( by Parallelogram law)
4x - 5 = 2 (x + 5)
4x - 5 = 2x + 10
4x - 2x = 10 + 5
2x = 15
x = 15/2
x = 7.5

Step-by-step explanation:
h²=o²+a²
a²=8²+5²
a²=64+25
a²=89
a=√89
a=9.433
To one decimal place it is 9.4
for b,
h²=o²+a²
17²=b²+12²
289=b²+144
289-144=b²
145=b²
b=√145
b=12.041
To one decimal place it is 12.0
Answer:
Therefore Nat deposited $500 when he opened the account.
Step-by-step explanation:
Given that Nat opened an account that earns 1.4% simple annual interest. He will earn $21 total interest after t years.
The simple interest formula is
I= interest= $21
P= Principal=?
t= time in year= 3 years.
r = rate of interest= 1.4%= 0.014
=$500
Therefore Nat deposited $500 when he opened the account.
Answer:
Given :
The length of a rectangle is 4 cm more than its width
The area of the rectangle is 96 cm²
To Find :
Width of the rectangle.
Solution :
Let the length of the rectangle be x cm.
Let the breadth of the rectangle be y cm.
Case 1:
➣
➣ _____(1)
Case 2 :
We have the formula for area of the rectangle as follows :
Where,
l = length → x cm
b = breadth → y cm.
➣
➣
Substitute, x = 96/y in equation 1,
