Answer:

a)  963g

b) 17

Step-by-step explanation:

i) Now we must first find the common difference of the AP

d = 7.8 -6 = 1.8

Now the sum of the AP gives the total amount of chemical used for 30 experiments

Sn = n/2 [2a + (n-1)d]

n= 30, a = 6, d= 1.8

Sn = 30/2[2(6) + (30-1) (1.8)]

Sn = 15[12 + 52.2]

Sn = 963g

ii)For the G.P the common ration is (r)= 7.8/6 = 1.3

Since r>1, sum of GP = a (r^n -1)/r-1

If sum =  1800g

1800= 6(1.3^n -1)/1.3 - 1

1800 = 6(1.3^n -1)/0.3

1800 * 0.3  = 6(1.3^n -1)

540 = 6(1.3^n -1)

540/6 = (1.3^n -1)

90 = 1.3^n -1

90 + 1 = 1.3^n

1.3^n = 91

log 1.3^n = log 91

nlog1.3 = log 91

n = log91/log 1.3

n = 1.959/0.114

n = 17

Answer:

The cost of painting the curved surface of pillar is: 68.69

Step-by-step explanation:

Given that

Diameter of pillar = d = 50 cm

As the height is in meters and we have to find the cost in per square meter, we have to convert cm into meters.

So,

d = 50/100 = 0.50 m

Now the radius will be:

[tex]r = \frac{d}{2} = \frac{0.50}{2} = 0.25m[/tex]

Also

Height = 3.5m

The curved surface area of cylinder is given by:

[tex]CSA = 2\pi rh[/tex]

Putting the values

[tex]CSA = 2 * 3.14 * 0.25 * 3.5 = 5.495\ m^2[/tex]

It is given that the cost per square meter is 12.50

The total cost for 5.495 m^2 will be: 12.50 * 5.495 = 68.6875

Rounding off to nearest hundredth: 68.69

Hence,

The cost of painting the curved surface of pillar is: 68.69

the subtraction property of equality

Step-by-step explanation:

We use the "subtraction property of equality" to solve for the unknown in the equation:

subtract 5 from both sides:

c + 5 - 5 = 78 - 5

c = 73

Answer:

burritos cost $4

tacos cost $ 1.75

Step-by-step explanation:

let b represent the price of burritos

let t represent the price of tacos

3b + 4t = 19

5b + 3t = 25.25

multiply the first equation by -3 and second by 4 to eliminate t

-3(3b + 4t = 19)

4(5b + 3t = 25.25)

-9b - 12t = -57

20b + 12t = 101

add both equations

11b  = 44

11       11

b = 4

substitute b = 4 into any equation to find the price of tacos

3b + 4t = 19

3(4) + 4t = 19

12 + 4t = 19

-12          -12

4t = 7

4    4

t = 1.75

Answer:

Each fudge cookie has 80 calories.

Each lemon cream has 65 calories.

Step-by-step explanation:

We will let [tex]\ell[/tex] represent the calories in lemon creams and [tex]f[/tex] represent the calories in fudge cookies.

Two lemon creams and four fudge cookies together have 450 calories. So, we can write the following equation:

[tex]2\ell+4f=450[/tex]

And four lemon creams plus two fudge cookies together have 420 calories. So, we can write the following equation:

[tex]4\ell+2f=420[/tex]

We now have a system of equations. We can solve this by elimination.

For the first equation, we can multiply both sides by -2. This way, the [tex]\ell[/tex] will cancel when we add the two equations together.

So, the first equation becomes:

[tex]-4\ell-8f=-900[/tex]

Add this to the second equation. Hence:

[tex](-4\ell+4\ell)+(-8f+2f)=(-900+420)[/tex]

Simplify:

[tex]-6f=-480[/tex]

Divide both sides by -6. Hence:

[tex]f=80[/tex]

So, there are 80 calories in one cookie.

We can use the first equation again to find the amount of calories in one cream. We have:

[tex]2\ell+4f=450[/tex]

Substituting 80 for [tex]f[/tex] yields:

[tex]2\ell+320=450[/tex]

Then it follows that:

[tex]\ell=65[/tex]

So, there are 65 calories in each lemon cream.

Answer:

  (x, y) = (10, 2)

Step-by-step explanation:

The upper angle marked with an expression in x and y is supplementary to the angle marked 70°. The lower angle marked with an expression in x and y is an alternate interior angle with respect to the one marked 70°, is equal to that. This gives the two equations in x and y:

  6x +10y +30 = 110

  4x +10y +10 = 70

Subtracting the second equation from the first gives ...

  2x +20 = 40

  x +10 = 20 . . . . . divide by 2

  x = 10 . . . . . . . . . subtract 10

Substituting into the second equation gives ...

  4(10) +10y +10 = 70

  4 + y + 1 = 7 . . . . . . . . divide by 10

  y = 2 . . . . . . . . . . . . . . subtract 5

The values of x and y are 10 and 2, respectively.

Step-by-step explanation:

His raise is 3% of 89.000

.03*89.000=$2.670

His new salary is ( to get the number you need to add 89.000+2.670={$91.67})

Tait's raise in the coming year will be $2,670

Question meant to say that the inflation is 3%.

Inflation refers to the general rise in the price of goods and services in a country. It therefore makes a currency weaker because that currency will only be able to buy less than it could before.

The raise will have to be 3% as well to ensure that inflation does not affect Tait

The raise is based on his salary so can be found by:

= Amount Tait earns x Inflation rate

= 89,000 x 3%

= $2,670

In conclusion, the raise is $2,670

Sum of Interior Angles = (Number of Sides -2) • 180 degrees

Sum of Interior Angles =  29 * 180

Sum of Interior Angles =  5,220

The interior angle sum of 31-gon is A = 5220°

What is the sum of the interior angles of a polygon?

The sum of the interior angles of a polygon is given by the formula

Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

where n is the number of sides

θ = angle in degrees

Given data ,

Let the interior angle sum of the polygon be = A

Now , the value of A is calculated by

The number of sides of the polygon n = 31

So , the interior angle sum of the 31-gon is given by the equation

Sum of Interior angles of a polygon with n sides is

nθ = 180 ( n - 2 )

where n is the number of sides , so

Substituting the values in the equation , we get

The value of nθ = 180 ( n - 2 )

The value of nθ = 180 ( 31 - 2 )

The value of nθ = 180 x 29

The value of nθ = 5220°

Therefore , the value of A is 5220°

Hence , The interior angle sum of 31-gon is A = 5220°

Answer:

1/2 or 50% probability

Step-by-step explanation:

There are just two players, player A and player B. Since it is between this two players, for player A to score first we would have:

AB where player A is the first player to score, we wouldn't have BA since player would not be the first here

Probability = number of favorable outcomes/total number of outcomes

Therefore probability of A being the first player = number of A/total number of players

=1/2 = 0.50

There is therefore a 50% chance of A being the first player

Answer:

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex]

[tex]f(f^{-1}(x)) = f^{-1}(f(x))= x[/tex]

Step-by-step explanation:

Given

[tex]f(x) = \frac{2}{3}x - 6[/tex]

Required

Determine [tex]f^{-1}(x)[/tex]

[tex]f(x) = \frac{2}{3}x - 6[/tex]

Represent f(x) as y

[tex]y=\frac{2}{3}x - 6[/tex]

Swap the positions of x and y

[tex]x=\frac{2}{3}y - 6[/tex]

Add 6 to both sides

[tex]x+6=\frac{2}{3}y - 6+6[/tex]

[tex]x+6=\frac{2}{3}y[/tex]

Multiply both sides by 3

[tex]3(x+6)=\frac{2}{3}y * 3[/tex]

[tex]3(x+6)=2y[/tex]

Divide both sides by 2

[tex]\frac{3}{2}(x+6)=\frac{2y}{2}[/tex]

[tex]\frac{3}{2}(x+6)=y[/tex]

[tex]y= \frac{3}{2}(x+6)[/tex]

Replace y with [tex]f^{-1}(x)[/tex]

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex]

Justify the result:

First, we solve for [tex]f(f^{-1}(x))[/tex]

[tex]f(x) = \frac{2}{3}x - 6[/tex]

[tex]f(x) = \frac{2}{3}x - 6[/tex] becomes

[tex]f(f^{-1}(x)) = \frac{2}{3}x - 6[/tex]

Substitute [tex]\frac{3}{2}(x + 6)[/tex] for x

[tex]f(f^{-1}(x)) = \frac{2}{3}(\frac{3}{2}(x + 6)) - 6[/tex]

[tex]f(f^{-1}(x)) = \frac{2*3}{3*2}(x + 6)- 6[/tex]

[tex]f(f^{-1}(x)) = \frac{6}{6}(x + 6)- 6[/tex]

[tex]f(f^{-1}(x)) = 1*(x + 6)- 6[/tex]

[tex]f(f^{-1}(x)) = x + 6- 6[/tex]

[tex]f(f^{-1}(x)) = x[/tex]

Next, we solve [tex]f^{-1}(f(x))[/tex]

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex]

[tex]f^{-1}(x)= \frac{3}{2}(x+6)[/tex] becomes

[tex]f^{-1}(f(x))= \frac{3}{2}(x+6)[/tex]

Substitute [tex]\frac{2}{3}x - 6[/tex] for x

[tex]f^{-1}(f(x))= \frac{3}{2}(\frac{2}{3}x) - 6+6[/tex]

[tex]f^{-1}(f(x))= \frac{3}{2}(\frac{2}{3}x)[/tex]

[tex]f^{-1}(f(x))= \frac{2*3}{3*2}x[/tex]

[tex]f^{-1}(f(x))= \frac{6}{6}x[/tex]

[tex]f^{-1}(f(x))= 1*x[/tex]

[tex]f^{-1}(f(x))= x[/tex]

Hence:

[tex]f(f^{-1}(x)) = f^{-1}(f(x))= x[/tex]
