Answer:
12 °F
2°F per hour
Step-by-step explanation:
The difference can be found by substracting:
7°F-( -5 °F)
=12 °F
To find the average change in temperature per hour, divide by how many hours between 6 to midnight. Between 6 to midnight is 6 hours.
12°F / 6 hours
= 2°F/ hour
Answer:
Step-by-step explanation:
Evaluating the numerator and denominator before evaluating
Using the rule of exponents
⇔ , = 1
Thus
y² ← substitute values into expression
= × 4² = × 16 =
and denominator
= 1 × 4³ = 1 × 64 = 64
Now dividing
÷ 64
= × ( cancel 16 and 64 )
= =
Area is base x height
8cm is the base , 8 cm is the height
8x8=64cm
Given:
LMN is an equilateral triangle.
LM = LN = MN = 12 cm
To find:
The height of the triangle h.
Solution:
In a right angle triangle,
Multiply both sides by 12.
Therefore, the height of the triangle is cm.
