Answer:
Tell me the problem and I'll be glad to help!
First convert the dimensions of the pyramid from feet to yards.
1 yard = 3 feet.
756 feet / 3 ft per yard = 252 yards.
480 feet / 3 ft per yard = 160 yards.
The formula for volume of a pyramid is: Area of the base x the height divided by 3.
Volume = 252 yds^2 x 160/3 = 63504 x 160/3 = 3,386,880 cubic yards.
Now to find the number of bricks needed. divide the total volume by the volume of 1 brick:
3,386,880 / 1.5 = 2,257,920 total bricks.
Answer:
x = 3,-5 is correct.
Step-by-step explanation:
The Zero Product Property:
The Zero Product Property simply tells that if a*b=0, it implies that either a=0 or b=0 (or the both of them must be equal to zero). The product of the factors is zero if and only if the one or more of factors is zero. This is particularly useful for solving the quadratic equations .
In the given question the quadratic equation is (x-3)(x+5)=0
from the Zero Product Property, it is clear that x-3 =0 or x =3
x+5 =0 or x=-5
Therefor x = 3,-5 Hence option 3 is correct.
Answer:
31 1/3
Step-by-step explanation:
3x-10=84, given
3x=94, add 10 to both sides
x = 31 1/3, divide both by three
