Answer:
First evening: 8 phone calls
Second evening: 60 phone calls
Third evening: 15 phone calls
Step-by-step explanation:
third evening: x
second evening: 4x
first evening: x - 7
x + 4x + x - 7 = 83
6x = 90
x = 15
First evening: x - 7 = 15 - 7 = 8
Second evening: 4x = 4(15) = 60
Third evening: x = 15

The curved surface area using the formula 2πrh is, 80π cm².
What is a cylindrical shape?A cylinder is a three-dimensional solid object with two bases that are identically circular and are connected by a curving surface that is located at a specific height from the center.
Examples of cylinders are toilet paper rolls and cold beverage cans.
The volume of a cylinder is πr²h.
Curved surface area = 2πrh.
Total surface area = 2πr(h + r).
Given, A cylinder having a height of 8 cm and a radius of 5 cm.
Therefore, The curved surface area of this cylinder having a height of 8 cm and a radius of 5 cm is,
= 2×π×5×8 cm².

85 percent of what is 64.6?
Answer:
54.91
Step-by-step explanation:
64.6/x=100/85
(64.6/x)*x=(100/85)*x
64.6=1.17*x (divide both sides of the equation by 1.17 to get x)
54.91=x
x=54.91
now we have 85% of 64.6= 54.91
Answer:
76
We make the assumption that 85 is 100% since it is our output value.
Step 2: We next represent the value we seek with $x$.
Step 3: From step 1, it follows that 100% = 85

In a sequence, we know that t(11)= 22. We also know that the common difference is -4.
What is t(13)?
t(13) = ______
Answer:
Step-by-step explanation:
I hope this means t_11 = 22
If it means t(11) = mx + b where x winds up being 11 and t(x) = 22, we have an entirely different problem. I'll try them both
t_11 = 22
t_11 = 22
d = - 4
what is a (where does this thing start).
L = a + (n - 1)*d
22 = a + (11 - 1)*-4
22 = a + 10*-4
22 = a - 40
a = 62
So finding t(13) is
L = 62 + (13 - 1)*-4
L = 62 + 12 * - 4
L = 62 - 48
L = 14
======================
I think this is the only way to interpret it. If you get an answer explaining it, I'd take that answer.
Answer:
t(13) = 14
Step-by-step explanation:
Given t(11) = 22 and d = - 4
Then to obtain the next term in the sequence subtract 4 from the previous term, that is
f(12) = f(11) - 4 = 22 - 4 = 18
t(13) = t(12) - 4 = 18 - 4 = 14
27. The interest rate that doubles a sum in 10 years is
a) 12%
b) 11%
c) 10%
d) 9%
Answer:
Interest rate of 7%.
Step-by-step explanation:
The compound interest formula is given by:
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
Where A(t) is the amount of money after t years, P is the principal(the initial sum of money), r is the interest rate(as a decimal value), n is the number of times that interest is compounded per year and t is the time in years for which the money is invested or borrowed.
In this question:
We want to find t for which [tex]A(t) = 2P[/tex] when [tex]n = 1, t = 10[/tex]. So
[tex]A(t) = P(1 + \frac{r}{n})^{nt}[/tex]
[tex]2P = P(1 + r)^{10}[/tex]
[tex](1 + r)^10 = 2[/tex]
[tex]\sqrt[10]{(1 + r)^10} = \sqrt[10]{2}[/tex]
[tex]1 + r = 1.07[/tex]
[tex]r = 0.07[/tex]
So a interest rate of 7%.

Mason invested $65,000 in an account paying an interest rate of 4.6% compounded
annually. Assuming no deposits or withdrawals are made, how long would it take, to
the nearest year, for the value of the account to reach $142,200?
Answer:
t≈17
Step-by-step explanation:
The time would take is approximately 17 years for the value of the account to reach $142,200.
How to calculate compound interest's amount?If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:
[tex]CI = P\left(1 +\dfrac{R}{100}\right)^T - P[/tex]
The final amount becomes:
[tex]A = CI + P\\A = P\left(1 +\dfrac{R}{100}\right)^T[/tex]
We are given that;
P = $65,000 r = 0.046 n = 1 (compounded annually) A = $142,200
Now,
To find how long it would take for the value of the account to reach $142,200, we need to solve for t using this formula.
Plugging these values into the formula, we get:
142200 = 65000 (1 + 0.046/1)^t
Simplifying and rearranging, we get:
(1.046)^t = 2.188
Taking logarithms on both sides, we get:
t log(1.046) = log(2.188)
Dividing by log(1.046), we get:
t ≈ 16.67
Rounding to the nearest year, we get:
t ≈ 17 years
Therefore, by the given compound interest the answer will be 17 years.

Answer:
C (-354, 294)
Step-by-step explanation:
The geometric explicit formula is gn= g1 · [tex]r^{n-1}[/tex].
N represents the term you are looking for which, in this case, is the 12th term. R represents the common ratio which, in this case, is +3.
G1 represents the first term in the sequence which, in this case, is -2.
Now you solve using this equation: g12 = -2 · [tex]3^{12-1}[/tex].
12 minus 1 is 11. [tex]3^{11}[/tex] is 177147. 177147 times -2 is -354294.
And that is your final answer; -354,294

You want to put a fence around your large yard. There are two companies that you have found to do the work. They have each given you a quote for how much the work will cost. Of course, you want to find out which company will be the cheapest. The boundary of your yard is determined by five trees. The lines connecting them form the edge of your property. Shown below are the descriptions for the positions of the trees relative to your house.
TREE Position (relative to your house)
1 100 ft. east 2 40 ft east, 80 ft south 3 40 ft west, 120 ft south 4 90 ft west, 60 ft north 5 20 ft east, 110 ft north
STEP 1: On graph paper, mark the position of each of the trees on your land. Let each block of the graph paper represent a 10-foot by 10-foot square. Using a straightedge, connect Tree 1 to Tree 2, Tree 2 to Tree 3, Tree 3 to Tree 4, and so on.
STEP 2: Use the Pythagorean Theorem to find the length of each side of your property. Round
STEP 2
Length of segment 1 - 2 = √(8² + 6²) = 10 × 10 = 100 feet
Length of segment 2 - 3 = √(4² + 8²) = 4·√5× 10 = 40·√5 feet = 89.44 ft.
Length of segment 3 - 4 = √(5² + 18²) = √349 = 10·√349 feet = 186.82 ft.
Length of segment 4 - 5 = √(11² + 5²) = √146 = 10·√146 feet = 120.83 ft.
Length of segment 5 - 1 = √(11² + 8²) = √185 = 10·√185 feet = 136.01 ft.
