Answer:

27/5 or 5 2/5

Step-by-step explanation:

Assuming you mean 9 x 3/5

The answer would be

27/5

in Decimals, it would be

5.4

and in mixed numbers form it would be

5 2/5

Answer:

The rate of change is 25 and that means the cost per day is $25

Step-by-step explanation:

Since we have a constant rate of change, we can select any two points, apply the slope formula

The slope formula is;

m = (y2-y1)/(x2-x1)

(x1,y1) = (3,75)

(x2,y2) = (6,150)

m = (150-75)/(6-3) = 75/3 = 25

What the rate of change means here is that the cost per day is $25

Answer:

No. Remember, a right angle must have a 90 degree angle. We can find the lengths with the Pythagorean Theorem.

Step-by-step explanation:

Given the length 7, 10, and 12, we can assume that 12 is the hypotenuse (it is the longest length).

- we can use 7 and 10 interchangeably.

Fill in the equation, [tex]a^2 + b^2 = c^2[/tex]

                 where c = 12, and a or b = 7 or 10.

To indicate if the given lengths would form a right angle, we can only input 7 or 10, not both.

Therefore, [tex]7^2 + b^2 = 12^2[/tex] or [tex]10^2 + b^2 = 12^2[/tex]

[tex]7^2 + b^2 = 12^2[/tex] ==> 49 + b^2 = 144 ==> b= [tex]\sqrt{95[/tex] ==> 9.746

b= 9.7, not 10.

[tex]10^2 + b^2 = 12^2[/tex] ==> 100 + b^2 = 144 ==> b = [tex]\sqrt{44[/tex] ==> 6.633

b= 6.6, not 7.

Therefore, the lengths 7, 10, and 12, does NOT make a right triangle.

Hope this helps!

Answer:

36 units

Step-by-step explanation:

P = 12 + 12 + 6 + 6

picture the shaded semi-circle filling in the unshaded semi-circle and you have a 6 by 12 unit rectangle

Answer:

P = 69!

Step-by-step explanation:

23+17+29 = 69 :)

Answer:

P = 69

Step-by-step explanation:

P = A + B + C

A = 23

B = 17

C = 29

P = 23 + 17 + 29

P = 69

Answer:

Your answer is B

Step-by-step explanation:

The rule for angles is that 115 and the angles right next to it, the ones that form the x, will equal 180. That means all you have to do is 115-180=65.

Another rule is that the interior angles of a triangle will be 180, so you add the angles we know in each triangle, 80+65+angle 1 = 180. If you do this correctly you should get angle 1 to be 35. Then you repeat on the opposite side except this time the angles are 85+65+angle 2 = 180. If you do this one correct you should get 30. Which makes your answer B.

Sorry if this is confusing the book will have better explanations than I can give.

Answer:

$696.70

Step-by-step explanation:

The formula for the area of a circle is given as πr²

From the above question

π = 3.14

Diameter = 5 feet

Radius = Diameter/2 = 5 feet/2 = 2.5 feet

Hence,

The area of the circular table = 3.14 × 2.5²

= 19.625 ft² or 19.625 square foot

We are told that:

The wood costs $35.50 per square foot

Hence,

1 ft² = $35.50

19.625 ft² = x

Cross Multiply

x = 19.625 ft² × 35.50

x = $696.6875

Approximately = $696.70

Therefore, it will cost Rafael $696.70 to make the table.

Answer: 3 in.

Step-by-step explanation:

Given

The base of the triangle is [tex]3\frac{2}{5}\ inches[/tex]

The area of the triangle is [tex]5\frac{1}{10}\ inches^2[/tex]

Solve mixed fraction

Base is

[tex]=3\dfrac{2}{5}\\\\=\dfrac{17}{5}\ in.[/tex]

Area is

[tex]=5\dfrac{1}{10}\\\\=\dfrac{51}{10}\ in.^2[/tex]

The area of the triangle is given by

[tex]\Rightarrow \text{Area A=}\dfrac{1}{2}\times \text{base}\times \text{height}[/tex]

Insert the values to get the height

[tex]\Rightarrow \dfrac{51}{10}=\dfrac{1}{2}\times \dfrac{17}{5}\times \text{height}\\\\\Rightarrow \text{height}=3\ in.[/tex]

Answer:

Polly's money is 30, Andy's is 60, and Phoebe's is 180.

Step-by-step explanation:

Given that

Phoebe andy and polly share 270

Phoebe gets 3 times as andy

And, andy gets twice as much as polly

let us assume the following things

B be Phoebe's money

A be Andy's money

L be Polly's money

Now following equations should be used

B + A + L  = 270  .........(1)  

B = 3A............(2)

A = 2L      .............(3)          

So,        

B = 3A

= 3 × (2L)

= 6L        

Now put the equation 2 and equation 3 in equation 1

So,

6L + 2L + L = 270

9L = 270

L = 30

A = 2L

= 2(30)

= 60

B = 3A

= 3(60)

= 180

Therefore, Polly's money is 30, Andy's is 60, and Phoebe's is 180.

Answer:

430

Step-by-step explanation:

Given :-

And we need to find out the CP .So ,

Let :-

According to the Question :-

[tex]:\implies[/tex] 460 = x + y ( Profit)

[tex]:\implies[/tex] 400 = x - y ( Loss)

Adding both :-

[tex]:\implies[/tex] 460 + 400 = x + y + x - y

[tex]:\implies[/tex] 860 = 2x

[tex]:\implies[/tex] x = 860/2

[tex]:\implies[/tex] x = 430

Hence the Cost price of the watch is 430 .

Answer:

13 and 32

Step-by-step explanation:

let one number be x

Then the other number is x + 19 , then

x + x + 19 = 45

2x + 19 = 45 ( subtract 19 from both sides )

2x = 26 ( divide both sides by 2 )

x = 13

The 2 numbers are 13 and 13 + 19 = 32

Answer:

13 is right
