Answer 1

Step-by-step explanation:

Identity used :

[tex] \bold{ ({y}^{2} + {z}^{2}) = {y}^{2} + 2yz + {z}^{2} }[/tex]

[tex] \implies \: {(2y)}^{2} - 2.2y.3z + {(3z)}^{2} [/tex]

There are 15 dogs, 22 cats, and 4 rabbits at a shelter. Each dog needs a collar, bowl, and toy. Each cat needs a collar, bowl and 2 toys. Each rabbit needs a bowl. How many total toys will the shelter need?

Answers

Answer:

137 toys

Step-by-step explanation:

You take the number of dogs = 15

and how many things each dog needs = a collar, bowl, and toy

and you multiply 15 by three to get the number of collars, bowls, and toys each dog needs. Then repeat this process and add all of your answers

Dog = 60

Cat = 88

Rabbit = 4

88 + 60 + 4 = 137

(If the collar, and bowls don't count as toys then just message me and I will redo the math for you.)

Find the surface area of the cone with a diameter of 12 centimeters and a slant height of
85 millimeters.
Please answer due in 20 minutes

Answers

Answer:

lateral surface area is 160.14 square cm.

Total surface area is 273.16  square cm  

Step-by-step explanation:

Lateral surface area of cone is given by [tex]\pi rl[/tex]

where r is radius of cone

and l is slant height of cone.

l = 85 millimetres

we know that 10 millimetres is equal to 1 cm

Thus 85 millimetres is equal to 8.5 cm

Thus slant height(l) in cm is 8.5[tex]\pi rl\\=>\pi 6*8.5\\=> 3.14*51\\=>160.14[/tex]

we will use value of [tex]\pi[/tex] as 3.14

Diameter of cone = 12 cm

we know that radius is equal to half of Diameter

radius of given cone = 1/2 *Diameter = 1/2 * 12 = 6 cm.

Thus lateral surface area of cone is given by

[tex]\pi rl\\=>3.14*6*8.5\\=>153[/tex]

Thus, lateral surface area is 160.14 square cm.

Area of base of cone will be area of circular base

area of circle is given by [tex]\pi r^2[/tex]

Thus area of base is given below

[tex]\pi r^2\\=>3.14*6^2\\=>113.04[/tex]

area of base is 113.04 square cm

Total surface area of cone is sum of area of base and lateral surface area

Total surface area = 160.14+113.04 = 273.16  square cm.

By what number do you multiply the radius of a circle to double its area? Show the process to get the answer.

Answers

Answer:

Area of circle = πr²

New doubled area = πR² ( r ≠ R )

As it is double of older area :

πR² = 2πr²

R² = 2r²

R = √2r

Thus we have to multiply the radius to √2 to double its area

Raman have 72.75 M long string he cut the string in certain species of equal length if one piece is 14.55 M long how many pieces are cut out of from the rope

Answers

Answer:

5

Step-by-step explanation:

Raman have 72.75 M long string and he cut the string in pieces of equal length of 14.55 M long .

To find how many pieces he cut, we simply divide the length of the original piece of string by the length of the cut piece of string.

That is:

72.75 / 14.55 = 5

He can cut 5 pieces of string.

In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial. What is the result of applying the square root property of equality to this equation?

Answers

Answer:

The result is

x + b/2a= ±√[(b² - 4ac)/2a]

Step-by-step explanation:

In the derivation of the quadratic formula by completing the square, the equation is created by forming a perfect square trinomial

ax² + bx + c = 0

x² + (b/a)x + c/a = 0

x² + 2(b/2a)x + b²/4a² - b²/4a² + c/a = 0

(x + b/2a)² - b²/4a² + c/a = 0

(x + b/2a)² = b²/4a² - c/a

(x + b/2a)² = (b² - 4ac)/2a

Apply square roots to both sides

x + b/2a= ±√[(b² - 4ac)/2a]

What is the measure of the missing angle?

Answers

Answer:

answer is 60

Step-by-step explanation:

because if the angle is 60 degrees anywhere in the triangle means its an equilateral triangle making all the angles 60 degrees

Answer:

60 degrees

Step-by-step explanation:

Every Triangle has an angle of 180 degrees

so if we add all of the written angles which is 25 + 35 + 60 = 120

we take 180 degrees and subtract it with the previous answer (120)

180 - 120 = 60

Therefore it is 60 degrees

Two joggers run 8 miles north and then 5 miles west. What is the shortest distance , to the nearest tenth of a mile, they must travel to return to their starting point?
PLSS HELP EXTRA POINTS, WILL GIVE BRANLIEST!!

Answers

Answer:

9.4 miles

Step-by-step explanation:

We can assume that if these joggers run 8 miles north, consecutively 5 miles west, these lengths form legs of a right angle triangle, from which we have to determine the hypotenuse of the triangle provided it would lead to the shortest route possible;

Knowing this is a right angle triangle, let us apply Pythagorean Theorem to solve for the length of this hypotenuse, which we can assign as x;

8^2 + 5^2 = x^2 ⇒ square 8 and 5,

64 + 25 = x^2 ⇒ Combine like terms,

x^2 = 89 ⇒ Take square root on either side

Solution; Shortest Distance ⇒ length of 9.4 miles

The dimensions of a CD case are 14.2cm by 12.5cm. Each case is approxiomately 1cm deep. What would be the volume of this stack of 17 cd cases to the nearest tenth?

Answers

Answer:

3017.5 cm³

Step-by-step explanation:

The volume of a rectangular prism is V = l × w × h

Here the length is 14.2, the width is 12.5, and the height is 1

Plugging these into our formula we get V = (14.2)(12.5)(1) = 177.5 cm³

Since there are 17 CD cases stacked on top of each other, we will multiply our number by 17 which gives us (177.5)(17) = 3017.5 cm³

Answers

Answer:

A.

Step-by-step explanation:

Given that point P partitions a directed line segment from A to B into the ratio 3:4, we are to determine how close P is to either A or B.

To do this, we take an example.

Let the length of line segment AB be 14 Units.

Since P divides AB in the ratio 3:4

Length of AP[tex]=\frac{3}{7}X14=6 \:units[/tex]Length of PB[tex]=\frac{4}{7}X14=8 \:units[/tex]

Therefore, from the above, we can conclude that P will be closer to A as its distance from A is shorter than its distance from B.

The correct option is A.

Answer:

Point P partitions the directed line segment from A to B into the ratio 3:4. Will P be closer to A or B? Why?

A number line goes from point A to point B. A line is drawn from point A to point B.

Right Answer  A.)   P will be closer to A because it will be Three-sevenths the distance from A to B.  

Wrong Answer  B.)   P will be closer to A because it will be Four-sevenths the distance from A to B.

What are the one solution ?

One Solution Equation is when an equation has only one solution. This means that when you solve an equation, the variable can only be subsituted by one number to make an equation true.

So, when the two lines passes and intersect at one point it forms one solution so that is why option (A) is correct i.e., On a coordinate plane, two lines intersect at one point.
