Answer:
Step-by-step explanation:
e
1/4 foot = 3 inches.
The area of a 1/4-ft square is (3" x 3") = 9 square inches.
1/3 foot = 4 inches.
The area of a 1/3-ft square is (4" x 4") = 16 square inches.
The 1/3-ft square tile covers more area than a 1/4-ft square tile
covers. So she won't need as many 1/3-ft tiles to cover the floor
in her room. She will use fewer of those.
Step-by-step explanation:
54mn⁴ = 2 * 3³ * m * n⁴
27m³n² = 3³ * m³ * n²
Highest common power of 2 = null
Highest common power of 3 = 3³
Highest common power of m = m
Highest common power of n = m²
Hence GCF(54mn⁴,27m³n²)
= 3³ * m * n² = 27mn².
27, m, n² and 9 are factors of the GCF 27mn². Only 18 is not a factor.
Answer:
<u>The two numbers are 25 and 15.</u>
Step-by-step explanation:
Let's find out the two numbers, this way:
x = first number
y = second number
This is the equations system:
x + y = 40
x - y = 10
Solving for x in the first equation:
x + y = 40
x = 40 - y
Solving for y in the second equation:
40 - y - y = 10
40 - 2y = 10
-2y = 10 - 40
-2y = - 30
<u>y = -30/-2 = 15</u>
Solving for x:
x + y = 40
x + 15 = 40
x = 40 - 15
<u>x = 25</u>
<u>The two numbers are 25 and 15.</u>
10) x+(x+20)+(2x+10)+(x+40)=180 degrees
5x+70=180
5x=110
x=22
