If 3 oranges cost $1.75, how much would 18 oranges cost?

Answer:

[tex]S_{10}=280[/tex]

Step-by-step explanation:

Given that,

[tex]t_n=2n+3[/tex] ...(1)

We need to find the value of [tex]S_{10}[/tex].

Put n = 1 to find the first term.

[tex]t_1=2(1)+3=5[/tex]

Put n = 2 to find the second term.

[tex]t_2=2(2)+3=7[/tex]

Put n = 3 to find the third term.

[tex]t_3=2(3)+3=9[/tex]

Put n = 10 to find the tenth term.

[tex]t_{10}=2(10)+3=23[/tex]

It means we need to find the sum of 5,7,9,.....,23.

The formula for the sum of n terms is given by :

[tex]S_=\dfrac{n}{2}(a+a_n)[/tex]

We have, n = 10, a = 5 and [tex]a_n=23[/tex]

So,

[tex]S=\dfrac{10}{2}(5+23)\\\\S_{10}=10\times 28\\\\=280[/tex]

So, the value of [tex]S_{10}[/tex] is equal to 280.

Step-by-step explanation:

Answer:

Explained below

Step-by-step explanation:

A rational number is one that can be expressed in form a of a fraction whereby both the numerator and the denominator are integers.

Also, if it results in a recurring decimal it is still a rational number but if the decimal is not recurring, then it is not a rational number.

Now, for example let's consider the number 5.

It is a rational number because it can be expressed as; 5/1; 10/2; 20/4; -5/-1 e.t.c

Now, the opposite of these fractions like we are told to check in the question results in;

1/5; 2/10; 4/20; -1/-5;

The opposite will give us still a rational number because both numerator and denominator are still integers and also the value of the division is 0.2 which is a definite decimal and also can be expressed as an integer.

Answer:

NRs. 8925

Step-by-step explanation:

176 dollars = 100 pounds

132 dollars = ??? pounds

Using cross-multiplication, we get:

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Now, 1 pound = NRs. 119

So 75 pounds = NRs. ???

Using cross-multiplication again, we get:

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925  

So the answer is 8925 Nepali rupees

The Nepali rupees can be exchanged with 132 dollar should be considered as the NRs. 8925

Since

176 dollars = 100 pounds

And, for 132 dollars = ??? pounds

So here we applied cross multiplication

176 dollars x ??? pounds = 100 pounds x 132 dollars

??? pounds = (100 pounds x 132 dollars)/ 176 dollars

??? pounds = 75 pounds

Also, 1 pound = NRs. 119

Now

1 pound x NRs. ??? = NRs. 119 x 75 pounds

NRs. ??? = (NRs. 119 x 75 pounds)/1 pound

NRs. ??? = NRs. 8925

Common Sense

The number of different ways committees can be formed will be 21.

A permutation is an act of arranging items or elements in the correct order. Combinations are a way of selecting items or pieces from a group of objects or sets when the order of the components is immaterial.

A committee is to consist of two members.

If there are seven people available to serve on the committee.

If two people are selected from the group of seven people.

Then the number of different ways committees can be formed will be

⇒ ⁷C₂

⇒ 7! / [(7 – 2)! x 2!]

⇒ 7! / [5! x 2!]

⇒ 7 x 6 x 5! / [5! x 2 x 1]

⇒ 7 x 6 / 2

⇒ 7 x 3

⇒ 21

Thus, the number of different ways committees can be formed will be 21.

Step-by-step explanation:

Hope it helps!

Answer:

x = 14.1

Step-by-step explanation:

Reference angle = 62°

Side opposite to reference angle = x

Hypotenuse = 16

Applying trigonometric ratio, thus:

Sin 62 = x/16

Multiply both sides by 16

16*sin 62 = x

14.1271615 = x

x = 14.1 (nearest tenth)

Answer:

y = 2x - 17

Step-by-step explanation:

y = mx + b

m = 2

y = 2x + b

Plug in (5, -7) for x & y.

-7 = 2(5) + b

-7 = 10 + b

Subtract 10 from both sides.

-17 = b

y = 2x - 17

Check work.

-7 = 2(5) - 17

-7 = 10 - 17

- 7 = -7

Your answer is correct.
