Answer:
3 1/3 feets
Step-by-step explanation:
Given that:
Height of aquarium = 1 3/4 feets
Area of aquarium = 5 5/6 ft²
The length of aquarium = x
Aquarium is shaped in the form of a rectangle :
Area of a rectangle = Length * width
5 5/6 = x * 1 3/4
35/6 = 7x/4
Cross multiply :
7x * 6 = 35 * 4
42x = 140
x = 140 / 42
x = 3 14/42
x = 3 1/3 feets
Hence, Length of the back of aquarium is 3 1/3 feets
Answer:
m∠1 = 148° and m∠2 = 32°
Step-by-step explanation:
m∠1 + m∠2 = 180° (supplementary angles)
4x° + (x - 5)° = 180 (substitution)
4x + x - 5 = 180
5x - 5 = 180
5x = 185
x = 37
m∠1 = 4(37)° =148° and m∠2 = (37 - 5)° = 32°
Answer:
the answer is c
Step-by-step explanation:
I done the math, trust me
Negatives cancel out positives so the +after the 4 changes to a minus and removes the - in the 3 so the equation changes to
-4 - 3 + 6 to make it easier, use the commutative property, 6 - 4 - 3 which equals -1
It's simple. as long as it's a 10 you just put in however many 0 it has as the root to a 1. or just multiply it however many times.
10x10x10 = 1000
so 10^3 = 1000
then you finish
4.23 x 1000 = 4230
