Answer:
10.8 m²
Step-by-step explanation:
To find area, we do 3.14*r^2
since diameter = 2 radius divide each by 2
2 and 0.75
A outer= 3.14*2^2
3.14*4
12.56 m²
A inner = 3.14*0.75^2
≈1.8 m²
to find the shaded area subtract the outer from the inner
12.56-1.8=10.76
which rounds up to
10.8 m²
If we use π then we get
about
12.57
and
1.77
subtract to get
10.8 m²

Write an explicit formula for a_na

, the n^{\text{th}}n
th
term of the sequence 25, 32, 39, ...25,32,39,....
Answer:
7n + 18
Step-by-step explanation:
it goes up in 7 so 7n and 25-7 =18
The Explicit formula for nth term is 18 + 7n.
What is Explicit Formula?It is simple to calculate the explicit formula for the arithmetic sequence from the term of the sequence.
The explicit formula for the arithmetic sequence a, a + d, a + 2d, a + 3d,........a + (n - 1)d, and the nth term of the sequence.
We have the sequence 25, 32, 39, ....
This is an arithmetic sequence.
First term = 25
and, Common difference(d) = second term - first term = 32-25 = 7
Now, the nth term of sequence
= a + (n- 1)d
= 25 + (n-1)7
= 25 + 7n - 7
= 18 + 7n

Answer with only a number, no units: Mohammed runs 3 1/4 miles in 1/2 an hour. What is his rate in miles per hour? *
Answer:
yes yes
Step-by-step explanation:
Answer: 6 & 1/2
This is a mixed number with 6 as the whole part and 1/2 as the fractional part.
Your teacher may want you to enter the answer without the ampersand symbol. If that's the case, then you would type in 6 1/2.
=============================================================
Work Shown:
1/4 = 0.25
3 & 1/4 = 3 + 1/4 = 3 + 0.25 = 3.25
1/2 = 0.5
He runs 3.25 miles in 0.5 of an hour
d = distance = 3.25 miles
t = time = 0.5 hour
r = unknown rate or speed in miles per hour (mph)
------------
distance = rate*time
d = r*t
3.25 = r*0.5
3.25 = 0.5r
0.5r = 3.25
r = 3.25/0.5 .......... divide both sides by 0.5
r = 6.5
r = 6 + 0.5
r = 6 + 1/2
r = 6 & 1/2
His rate is 6 & 1/2 mph
