The aquarium has a scale model of a great white shark for sale in their gift shop. If the scale of the model is 2 in. : 7 ft, what is the actual length of the shark if the shark is 4in?

Answers

Answer:

14ft

Step-by-step explanation:

Since the scale is 2in : 7ft, so you would do 7x2 which gets you to 14.

(You would do 7x2 because 4 in/2 in = 2in, that's where the 2 comes from, and 7 because 7ft is part of the scale.)

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board.

Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area.

Adam says he knows another way.


Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board.

1. What is the area of the board shown on the scale drawing? Explain how you found the area.

Find the height of a square pyramid that has a volume of 8 cubic feet and a base length of 2 feet.

1) 6 feet
2) 16 feet
3) 12 feet
4) 4 feet​

Answers

Step-by-step explanation:

Volume of square pyramid

= (Base length)² * (Height/3).

Therefore we have 8 = 2² * (h/3).

=> 8 = 4 * (h/3), h/3 = 2, h = 6.

Hence the height is 6 feet. (1)

Step-by-step explanation:

Common Sense

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

What are permutation and combination?

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.

if tñ=2ñ+3, find S10​

Answers

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.

Sarah's and 300% of Daniel's.
When they added their ages,
the total was 141. How old is

Answers

Answer:

27 years old

Step-by-step explanation:

Full question isDaniel's age is 15% of Sara's. Luke's age is 75% of Sara's and Rachel's is 300% of Daniel's. When they added their ages, the total was 141. How old is Rachel? Solution

Daniel = d, Sara = s, Luke = l, Rachel = r

We get below relations:

d = 0.15sl = 0.75sr = 3d ⇒ r = 3*0.15s  ⇒ r = 0.45s

Sum of ages:

d + s + l + r = 141

Substitute and solve for s:

0.15s + s + 0.75s + 0.45s = 1412.35s = 141s = 141/2.35s = 60

Rachel's age is:

r = 0.45*60 = 27

plz help

Answers

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.
