Answer:

$109.2

Step-by-step explanation:

Given data

Cost of bowling ball= $120

DIscount= 15%

Tax= 6%

let us calculate the discount and tax

=15/100*120

=0.15*120

=$18

=6/100*120

=0.06*120

=$7.2

In all the bill is 120-18+7.2

=102+7.2

=$109.2

Answer:

slope is undefined

Step-by-step explanation:

Calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = A(4, 6) and (x₂, y₂ ) = B(4, 3)

m = [tex]\frac{3-6}{4-4}[/tex] = [tex]\frac{-3}{0}[/tex]

Division by zero is undefined thus the slope of CD is undefined

Answer:

p= 1125

Step-by-step explanation:

p-275= 850

p- 275= 850

  + 275  +275

p= 1125

P= the original population minus D= decrease in population is equal to C= the current population

p-d=c

Answer:

1125 people

Step-by-step explanation:

We don't know the exact quantity, but we know it has decreased by 275 and it's currently 850, so we will represent it like this:

x - 275 = 850

x = original amount of people

Now we just solve it like any equation

x = 850 + 275

x = 1125

Answer:

S_6 = 252

Step-by-step explanation:

We are told that the 10th, 4th and 1st term of an A.P are three consecutive terms of a G.P.

Now,formula for nth term of an AP is;

a_n = a + (n - 1)d

Thus;

a_10 = a + (10 - 1)d

a_10 = a + 9d

Also;

a_4 = a + (4 - 1)d

a_4 = a + 3d

First term is a.

Thus, since they are consecutive terms of a G.P, it means that;

(a + 9d)/(a + 3d) = (a + 3d)/a

Cross multiply to get;

a(a + 9d) = (a + 3d)(a + 3d)

a² + 9ad = a² + 6ad + 9d²

a² will cancel out to give;

9ad - 6ad = 9d²

3ad = 9d²

Divide both sides by 3d to get;

a = 3d

We are told that the first term is 4.

Thus, 4 = 3d

d = 4/3

We saw earlier that ratio of the GP is (a + 3d)/a

Thus; r = (4 + 3(4/3))/4 = 8/4 = 2

Sum of n terms of a G.P is given by;

S_n = a(rⁿ - 1)/(r - 1)

S_6 = 4(2^(6) - 1)/(2 - 1)

S_6 = 252

Answer:

Step-by-step explanation:

In order to do f(g(4)), we need to find what g(4) is in order to input it into the function f(x).

g(4) = 2(4) = 8

Now do f(8) because that's the value of g(4)

f(8) = 3(8^2) - 3(8) + 6 = 174

Answer:

x(1) = -1

Step-by-step explanation:

Given the equation for acceleration of the object as;

a(t)=2(1-3t)

a(t) = 2-6t

Integrate to get the velocity

v(t) = 2t-6t²/2 + C

v(t) = 2t-3t²+C

If v(0) = -5

when t = 0 v = -5

-5 = 2(0)-3(0)²+C

-5 = C

C = -5

v(t) = 2t-3t²-5

To get the displacement x(t), we will integrate the velocity function

x(t) = 2t²/2-3t³/3-5t+C

x(t) = t²-t³-5t+C

If x(0) = 4

At t = 0, x(t) = 4

4 = 0²-0³-5(0)+C

4 = C

C = 4

x(t) = t²-t³-5t+4

Get x(1)

x(1) = 1²-1³-5(1)+4

x(1) = 1-1-5+4

x(1) = -5+4

x(1) = -1

Hence x(1) = -1

Answer:

23

Step-by-step explanation:

Angle x and the two given angles form a triangle. The interior angles of a triangle add up to be 180.

so

[tex]124 + 33 + x = 180[/tex]

[tex]157 + x = 180[/tex]

[tex]x = 23[/tex]

In the parallelogram below, the value of x is [tex]23^o[/tex] using the angle sum property .

The angle sum property states that:

The sum of all the interior angles of a triangle is [tex]180^o[/tex].

A  parallelogram is a four sided figure in which opposite sides are equal and parallel.

Given that:

A parallelogram in which the measurement [tex]124^o[/tex] and [tex]33^o[/tex] is given.

The parallelogram is divided into two triangles.

The value of x can be calculated as:

[tex]x+ 33^o + 124^o = 180^o[/tex] (Angle sum property)

[tex]157^o +x = 180^o[/tex]

    x =[tex]180^o- 157^o[/tex]

    x = [tex]23^o[/tex]

Thus, the value of x is [tex]23^o[/tex].

Answer:

It's 4

Step-by-step explanation:

* / = square root

You simply 2/72 which is 12/2, then simplify /8 which is 2/2.

You combine 2/2 and /2 which is 3/2.

The equation should be 12/2 over 3/2 so you simplify it which will give you 4.

(By simplifying 12/2 over 3/2, you cross out /2 and convert 12 over 3 into a whole number)
