Answer:
x ≈ 7.1
Step-by-step explanation:
The circumference of this circle is 2πx.
65/360 of that circumference is said to be 8
so we can solve x from
65/360 · 2πx = 8
which can be simlified to
2πx = 8 · 360/65
πx = 288/13
x = 288 / (13π) ≈ 7.1

12, 17, 22... find the 35th term
Answer:
a₃₅ = 182
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = 17 - 12 = 22 - 17 = 5
This indicates the sequence is arithmetic with n th term
[tex]a_{n}[/tex] = a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 5 , then
a₃₅ = 12 + (34 × 5) = 12 + 170 = 182
Work out the area of this semicircle with radius 3cm give your answer in terms of pie
Answer:
A=4.5π
The formula for finding a circle is A=πr² so just plug in the value for the radius. Don't forget to divide the entire thing by 2 when you finish, cos it's a semi circle (which is a half circle)
Step-by-step explanation:
Cos Milky Said it.
Answer:
Answer=4.5π
Step-by-step explanation:
you square 3 and then divide it by 2 and then just add pi

Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?
Answer: c = 8 + 0.03m
Step-by-step explanation:
From the question, we are informed that a company charges $8 per month and $0.03 per minute used.
The equation that best respresents the total cost for the month, c, for m miuntes used will be:
c = 8 + (0.03 × m)
c = 8 + (0.03m)
c = 8 + 0.03m
For example if 10 minutes was used, the cost will be:
c = 8 + 0.03m
c = 8 + (0.03 × 10)
c = 8 + 0.3
c = $8.3
There are 30 students in Mrs. Krzyzewski's class. None of them has a first name that begins with the letter "U" or the letter "Y." Eight of her students have first names that begin with "A," five have first names that begin with "E," two have first names that begin with "I", and three have first names that begin with "O."
Based on this data, what is the probability that a randomly-selected student from Mrs. Krzyzewski's class has a first name that begins with a consonant?

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98
=65.41

Which number sentence matches this model?
Answer:
D
Step-by-step explanation:
Find all solutions to the equation.
cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
