Answer:
15 inches
Step-by-step explanation:
Volume of a pyramid = 1/3 x ( length² x height)
4500 = 1/3 x ( length² x height)
height = 1/2 x length
4500 = 1/3 x ( length² x 1/2length)
multiply both sides of the equation by 6
27000 = ( length² x length)
find the cube root of 27300
length = 30
height = 1/2 x 30 = 15in

Answer:
So we will be saving a total of $0.7 at new rate
Step-by-step explanation:
Given:
Original price =$ 0.69
New price = $ 2.75 per 5 switches
To find:
Saving = ?
Solution:
The original per price of the switch is given as = $ 0.69
Discounted price of 5 switches at $2.75
5 Switch price at original price = Original price * No of switches
= 0.69 * 5
= $ 3.45
Total saving at buying 5 switches = 3.45 - 2.75
=$0.7
So we will be saving a total of $0.7 at new rate
Answer:
1,000,000
Step-by-step explanation:
addition and maths
Multiply the second equation by -3 in order to cancel out U
3u+z=15
-3(u+2z)=10
3u+z=15
-3u-6z=-30. Then u subtract those two equations
-5z=-15
Z=3
To solve for u, plug in the z in one of the equation (doesn’t matter which one)
3u+3=15
3u=12
U=4
Ur answer is
U=4. Z=3
