Write an expression for the area of square 4 by combining the areas of the four triangles and the two squares.

Answers

Answer 1

The area of square four is a² + b² + 2ab

How to calculate the area of square and triangle

The area of a square = l²

The Area so the two square = a² + b²

Area of the  triangles = 4(0.5ab) = 2ab

Add the area together

Area of the square four = area of square + area of 4 triangles

Area of the square four = a² + b² + 2ab

Hence the area of the square four is a² + b² + 2ab

if x+y=12 and xy=27 . find x^3+y^3
pls help with steps ​

Answers

Answer:

Step-by-step explanation:

use formula

x^3+y^3=(x+y)^3-3*x*y(x+y)

=12^3-3*27(12)

=1728-972

=756

Answer:

x^3 + y^3 = 756

Step-by-step explanation:

Given that,  x+y=12 and xy=27

We know that,

[tex]( x + y )^3 = x^3 + y^3 + 3xy(x + y)[/tex]

∴ [tex]12^3 = x^3 + y^3 + 3 * 27 * 12[/tex]

[tex]=> 1728 = x^3 + y^3 + 972[/tex]

[tex]x^3 + y^3 = 1728 - 972[/tex]

If Uber charges a $4.15 pickup fee plus $1.12 per mile, which equation can be used to calculate the cost of a ride of
x
x miles?

Answers

Answer:

4.15+1.12x

Step-by-step explanation:

So lets go over what we know.

The cost of a pickup is 4.15 dollars.

The cost of the pickup fee increases by 1.12 dollars per mile.

So when we start off, it will orginate as 4.15 dollars.

We know that this price is going to be increased by the other value, so we can write it as:

4.15+

We know that for each mile, this price goes up by 1.12.

If we went 10 miles, for instance, it would be 1.12 10 times, or 11.2 dollars.

So we know that thr 4.15 will be increased by 1.12 times the amount of miles.

Or:

4.15+1.12*m

=

4.15+1.12m.

Which question is a statistical question? A Which U.S. States have mountains?Which U.S. States have mountains?

C How many mountain ranges are in the U.S.?How many mountain ranges are in the U.S.? D How tall is the tallest mountain in the U.S.?

Answers

Answer: C. How many mountain ranges are in the U.S.

Step-by-step explanation:

A statistical question first of all has to have a quantitative response i.e., answers should be in numbers.

The only two questions here that would yield a numeric answer are options C and D.

Furthermore, a statistical question has variability in it which means that the answer is based on multiple observations not just one. The observations in option C are mountain ranges and as the question requires finding out details about multiple mountain ranges, this is a statistical question.

This is opposed to option D which addresses issues surrounding just one mountain.

A shopkeeper earns a profit of Rs. 1 by selling a pencil and a loss of 20 paisa by selling an eraser. In a given day he had a loss of Rs. 10. On this day, he sold 35 pencils. How many erasers were sold on this day

Answers

Given :

A shopkeeper earns a profit of Rs. 1 by selling a pencil and a loss of 20 paisa by selling an eraser.

To Find :

In a given day he had a loss of Rs. 10. On this day, he sold 35 pencils. How many erasers were sold on this day.

Solution :

Money earned by selling 35 pencils.

P = 35 × 1 = Rs 35 .

Now, it is given that he had a loss of Rs 10 .

Therefore, amount of loss done by money is :

E = 35 + 10

E = Rs 45

Now, number of erase sold :

[tex]n = \dfrac{E}{0.2}\\\\n = \dfrac{45}{0.2}\\\\n = 225\ erasers[/tex]

Hence, this is the required solution.

Answers

Answer:

1/2 = 0.5

Step-by-step explanation:

Given that the game company gave each customer a single game for testing

There is definitely just two outcomes, i.e. the customer will either recommend the game or Not recommend the game.

since we do not have additional information regarding what might influence the decision of the customer, hence the probability of either recommending the tested game or not recommending the game will be equal

∴P ( recommending tested game ) = 1 - 0.5 = 0.5

a person jogs 1/6 mile in 1/42 hour. what is the person's speed in miles per hour

Answers

So normally you would take the amount of miles and divide it by the hours to get a simple miles per hour.

Division of two fractions can be made easier by flipping the second fraction, and changing the operation to multiplication.

(1/6) / (1/42)
= (1/6) x (42/1)

From then, it is simply top x top, bottom x bottom.

= 42/6

Complete the division

= 7/1
= 7 miles per hour

(NR) Natural Resources:Question 10
Which statement best describes why large aquifers of groundwater are distributed unevenly
around the earth?

Answers

Answer: D) Groundwater collects only where the soil and geological features allow water to seep down into underground chambers.

In other words, as long as there are gaps to allow water through, then that would lead to underground aquifers. Another important component is the amount of rain water that happens. Sources such as rivers, lakes and streams are also a contributing factor.

Stuff like earthquakes, volcanic activity, and continental movement doesn't really have much an effect on where or how aquifers form. It's really all about the soil type and how the landscape is formed, and of course the other factors mentioned in the previous paragraph.

What is the approximate area of a circle with a diameter of 10 in?

A. 314 in2
B. 78.5 in2
C. 31.4 in2
D. 15.7 in2

Answers

Answer:

Hello! answer: 78.5 in2

Step-by-step explanation:

IMPORTANT ATTENTION: Im using 3.14 for pi so answers might vary if you are using say 22/7 for pi so please know that since this problem doesn't tell to use a certain method I will use 3.14

area can be found by doing radius × radius × 3.14 so... diameter is just twice the radius so... 10 ÷ 2 = 5 5 × 5 = 25

25 × 3.14 = 78.5 therefore 78.5 is the answer HOPE THAT HELPS!

The approximate area of a circle with a diameter of 10 in is,

⇒ Area of circle = 78.5 in²

Given that;

Diameter of circle = 10 in.

Now, We know that;

Area of circle = πr²

Where, 'r' is radius of circle.

Here, Diameter of circle = 10 in.

Hence, Radius = 10 / 2 = 5 in

Thus, We get;

⇒ Area of circle = πr²

Area of circle = 3.14 x (5)²

⇒ Area of circle = 78.5 in²

Thus, The approximate area of a circle with a diameter of 10 in is,

⇒ Area of circle = 78.5 in²
