Answer:
B. Miami is 93 degrees warmer than Anchorage.
Step-by-step explanation:
Miami-Anchorage is equal to 65-(-28) which is equal to 65+28 which is equal to 93. Thus, Miami is warmer by 93 degrees.
It depends if its decreasing 25% of the original quantity or decreasing by 25% of the quanity that is after already increasing by 25%.
Answer: 1 and 3
Step-by-step explanation:
4•3=12 and 2•3=6
Answer:
see explanation
Step-by-step explanation:
Given A is directly proportional to r² then the equation relating them is
A = kr² ← k is the constant of proportion
To find k use the condition when r = 5, A = 75 , then
75 = k × 5² = 25k ( divide both sides by 25 )
3 = k
A = 3r² ← equation of proportion
(a)
when r = 4, then
A = 3 × 4² = 3 × 16 = 48
(b)
when A = 147 , then
147 = 3r² ( divide both sides by 3 )
49 = r² ( take the square root of both sides )
r = 
= 7
The value of x is 14
<h3>How to solve for x?</h3>
From the question, the lines from the center of the circle to the chords have equal measures of 9 units
This line divides a chord into equal segments, where each segment is 7 units
So, we have:
x = 7 + 7
Evaluate
x = 14
Hence, the value of x is 14
