Answer:

-6665

Step-by-step explanation:

The given GP is :

1, -6, 36, ...

Number of terms = 6

The sum of n terms of a GP is given by :

[tex]S_n=\dfrac{a(r^n-1)}{r-1}[/tex]

Here,

a = 1, n = 6, r = 36/-6 = -6

So,

[tex]S_6=\dfrac{1((-6)^6-1)}{(-6)-1}\\\\=-6665[/tex]

So, the sum of th GP is -6665.

Answer:

x=1

Step-by-step explanation:

you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.

7x-10+10=3x-6+10

now it leaves you with 7x=3x+4

Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.

7x-3x=3x-3x+4

how it leaves you with 4x=4

now you divide both sides by 4

4/4x=4/4

Hence, x=1

Answer:

standard form: 4x - 4 = 0

factorisation: 4(x - 1) = 0

solutions: x = 4/4 = 1

therefore, x is 1

Answer: 2 terms

Step-by-step explanation:

There are two terms because

One is __x the other is the constant

9x + 4 - 3x + 7

6x + 4 - 7

6x - 3 has two terms

If the given mathemtical expression is simplified completely, the expression would contain 2 terms.

Given this expression: 9x + (4 – 3x) + 7

Remove the brackets : 9x + 4 - 3x + 7

Add similar terms: 6x + 11

Answer:

Step-by-step explanation:

which where is the equation

Answer:

No, because their respective prices are $0.75 and $2.25

Step-by-step explanation:

Let's assume that the price of each pretzel is x and the price of each soda is y

3x + 4y = 11.25_____ equation 1

5x + 2y = 8.25_____ equation 2

Multiply equation 2 by the figure 2 so as to have both equation sharing the same coefficient of y

10x + 4y = 16.5____ equation 1

3x + 4y = 11.25____ equation 2

Now subtract equation 2 from 1

7x = 5.25

X = 5.25/7

X = 0.75

Now substitute x = 0.75 in equation 1

10x + 4y = 16.5

10(0.75) + 4y = 16.5

7.5 + 4y = 16.5

4y = 16.5 - 7.5

4y = 9

Y = 2.25

Therefore,the cost of each pretzel is $0.75 while that of soda is $2.25

Given:

A fraction is greater than [tex]\dfrac{3}{12}[/tex], is less than [tex]\dfrac{75}{100}[/tex].

The fraction has 6 as a denominator.

To find:

The fraction value.

Solution:

Let x be the required fraction.

According to the given information, we get

[tex]\dfrac{3}{12}<x<\dfrac{75}{100}[/tex]

[tex]\dfrac{1}{4}<x<\dfrac{3}{4}[/tex]

We know that, [tex]\dfrac{1}{4}<\dfrac{2}{4}<\dfrac{3}{4}[/tex]. So,

[tex]x=\dfrac{2}{4}[/tex]

[tex]x=\dfrac{1}{2}[/tex]

We need 6 as the denominator.

Multiply the numerator and denominator by 3.

[tex]x=\dfrac{1\times 3}{2\times 3}[/tex]

[tex]x=\dfrac{3}{6}[/tex]

Therefore, the required fraction is [tex]\dfrac{3}{6}[/tex].

The fraction that Greg wrote is 3/6.

A fraction is a quantity that is not a whole number. A fraction usually has a numerator and a denominator. The numerator is the number above. While the denominator is the number below. An example of a fraction is 1/2.

The first step is to express 3/12 and 75/100 in its simplest form.

3/12 = 1/4

75/100 = 3/4

The second step is to determine the difference between the fractions

3/4 - 1/4

[tex]\frac{3 - 1}{4}[/tex] = [tex]\frac{2}{4} = \frac{1}{2}[/tex]

The third step is to multiply by 3

Answer:

volume of cylinder= pie × radius square× height

= 22/7×4×20

=1760/7

=251.42cm

Answer:

using 3 for pi it's V = 960cm^3

Step-by-step explanation:

R is the radius, which as stated, is half the diameter.

r = 8cm / 2 = 4cm

H is the height, which is shown to be 20cm

h = 20cm

V = pi*r^2*h

V = pi*(4cm)^2*20cm

substituting 3 for pi as requested.

V = 3*(4cm)^2*20cm - 3 * (16cm^2) * 20cm = 48cm^2 * 20cm = 960cm^3
