Answer:
3 years approx
Step-by-step explanation:
Given data
Principal=£100
Amount= £109.27
Rate= 3%
The expression for the compound interest is
A=P(1+r)^t
Make t subject of formula we have
t= ln(A/P) / r
t= ln(109.27/100)/ 3
t= ln(1.0927)/0.03
t= 0.088/0.03
t= 2.93
Hence the time is 3 years approx

A tennis club has 15 members: eight women and seven men. How many different teams may be formed consisting of one woman and one man on each team?
Answer:
12870ways
Step-by-step explanation:
Combination has to do with selection
Total members in a tennis club = 15
number of men = 8
number of women = 7
Number of team consisting of women will be expressed as 15C7
15C7 = 15!/(15-7)!7!
15C7 = 15!/8!7!
15C7 = 15*14*13*12*11*10*9*8!/8!7!
15C7 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2
15C7 = 15*14*13*12*11/56
15C7 = 6,435 ways
Number of team consisting of men will be expressed as 15C8
15C8 = 15!/8!7!
15C8 = 15*14*13*12*11*10*9*8!/8!7!
15C8 = 15*14*13*12*11*10*9/7 * 6 * 5 * 4 * 3 * 2
15C8 = 6,435 ways
Adding both
Total ways = 6,435 ways + 6,435 ways
Total ways = 12870ways
Hence the required number of ways is 12870ways

A college surveys local businesses about the importance of students as customers. The college chooses 150 businesses at
random from telephone listings. Of these, 68 return the questionnaire. The population being studied is:
A. The set of all local businesses
B. The 68 businesses who returned surveys
C. The 150 businesses who were sent surveys
D. All the students at the college
The proportion of businesses who did not respond = 54.67%
Given : Total businesses = 150
Businesses responded = 68
Businesses did not respond = 150- 68 = 82
The proportion of businesses who did not respond =
82/150 x 100
54.67%

Consider the functions F(x)= x^2+9x and g(x)=1/x.
F(g(-1))is ? , and G(f(1/2))is ? .
Answer:
a). -8 b). 4/19
Step-by-step explanation:
F(x)= x²+9x g(x)=1/x.
g(-1) = 1/ - 1
= -1
f(-1) = x²+9x
= -1² + 9(-1)
= 1 - 9
= -8
G(f(1/2))
f(1/2) = x²+9x
= 1/2² + 9(1/2)
= 1/4 + 9/2
= 19/4
g (19/4) = 1/x
= 1/19/4
= 4/19
Answer:
1). -8 2). 4/19
Step-by-step explanation:
F(x)= x²+9x g(x)=1/x.
g(-1) = 1/ - 1
= -1
f(-1) = x²+9x
= -1² + 9(-1)
= 1 - 9
= -8
G(f(1/2))
f(1/2) = x²+9x
= 1/2² + 9(1/2)
= 1/4 + 9/2
= 19/4
g (19/4) = 1/x
= 1/19/4
= 4/19

Solve the inequality -5(x - 1) > -40, and graph the solution on a number line.
Answer:
x<9
Step-by-step explanation:
-5(x-1)>-40
x-1>-40/-5
x-1>8
x>8+1
x>9
x<9
The solution of the inequality - 5(x - 1) > -40 will be;
⇒ x < 9
And, The solution of the inequality is shown in number line.
What is Inequality?
A relation by which we can compare two or more mathematical expression is called an inequality.
Given that;
The inequality is,
⇒ - 5(x - 1) > -40
Now,
Solve the inequality as;
The inequality is,
⇒ - 5(x - 1) > -40
⇒ - (5x - 5) > - 40
⇒ 5x - 5 < 40
Add 5 both side,
⇒ 5x - 5 + 5 < 40 + 5
⇒ 5x < 45
Divide by 5, we get;
⇒ x < 9
Thus, The solution of the inequality - 5(x - 1) > -40 will be;
⇒ x < 9
And, The solution of the inequality is shown in number line.

A bicycle tire is 28 inches in diameter how far does the bicycle move forward each time the wheel goes around use 22/7 as an approximately for π
Answer:
88 inches
Step-by-step explanation:
Well the bike will travel the distance of the circumference of the tire.
Circumference is 2*pi*radius or pi*diameter since the diameter is twice the radius
I guess they want is to use 22/7 for pi, which is weird, but whatever.
C = pi*d
C = 22/7*28
This gets you [tex]C = \frac{616}{7}[/tex] or 88 inches

Jeremiah and his children went into a bakery and he bought $20 worth of cupcakes and cookies. Each cupcake costs $5 and each cookie costs $1.25. He bought 4 times as many cookies as cupcakes. Graphically solve a system of equations in order to determine the number of cupcakes, x,x, and the number of cookies, y,y, that Jeremiah bought.
Answer: (2,8)
Step-by-step explanation:
5x+1.25=20
y=4x
5x+1.25y=20 y=4x
1.25y=-5x+20
1.25y/1.25=-5x+20/1.25
