Answer:
The answer is
<h2>126 feet</h2>
Step-by-step explanation:
Circumference of a circle is πd
Where d is the diameter
From the question
d = 40 feet
Circumference of the circle is
40π
= 125.66
= 126 feet to the nearest whole number
Hope this helps you
The first term in our arithmetic sequence = 13
The common difference of our arithmetic sequence = 17 - 13 = 4
The formula for finding an equation for any arithmetic sequence is a(n) = A + B(n - 1)
A = the first term
B = the common difference.
Let's plug our numbers in.
a(n) = 13 + 4(n - 1)
Let's check to make sure we're correct.
a(1) = 13 + 4(1 - 1) = 13 + 4(0) = 13 + 0 = 13
a(2) = 13 + 4(2 - 1) = 13 + 4(1) = 13 + 4 = 17
That verifies that our formula is correct.
In conclusion,
a(n) = 13 + 4(n - 1)
Answer:
First 15+4 which equal 19 and then multiply by 3 which equal 57
Step-by-step explanation:
Answer:
- m∠1=m∠4=m∠5=m∠8=67°;
- m∠2=m∠3=m∠6=m∠7=113°.
Step-by-step explanation:
Consider two parallel lines a and b with transversal m. These lines form 8 angles.
Note that
Since the difference of two angles is 46°, then these angles should be, for example, ∠1 and ∠2. These angles are supplementary, then
m∠1+m∠2=180°.
Solve the system of two equations:
Then
- m∠1=m∠4=m∠5=m∠8=67°;
- m∠2=m∠3=m∠6=m∠7=113°.
Answer:
H_0: p_1 =p_2\\H_a: p_1<p_2
Step-by-step explanation:
Given that in the past, 25% of the town residents participated in the school board elections.
The town officials recently undertook an extensive campaign to encourage registered voters to participate in the election process. They are interested in determining whether the promotional campaign actually increased the proportion of voters.
Let p1 be the proportion before camaign and p2 after campaign for voters.
Hence the correct set of hypotheses would be
