Find the value of x,y and z

Mathematics
1 answer:
krek1111 [17]4 years ago
4 0

x=\sqrt{70}, y =\sqrt{21}, z=\sqrt{30}

Solution:

Given c = 3 and d = 10 – 3 = 7

<u>To find the value of y:</u>

y^2= 3\times 7

y^2= 21

Taking square root on both sides of the equation.

y=\sqrt{21}

<u>To find the value of x:</u>

x^2=7\times10

x^2=70

Taking square root on both sides of the equation.

x=\sqrt{70}

<u>To find the value of z:</u>

z^2=3\times10

z^2=30

Taking square root on both sides of the equation.

z=\sqrt{30}

Hence the value of x=\sqrt{70}, y =\sqrt{21}, z=\sqrt{30}.

Bridget takes a 5-inch by 4-inch rectangle of fabric and cuts from one corner of the piece of fabric to the diagonally opposite
mario62 [17]

Answer:

Perimeter of each triangles are equivalent to 15.4 inches.

Step-by-step explanation:

Given:

A rectangle :

Length of the rectangle = 5 inches

Width of the rectangle =4 inches

As Bridget cuts it from one corner to the other corner,its forms two right angled triangle.

The diagonal will be treated as the hypotenuse.

Lets say that the length of the hypotenuse is 'x'.

Using Pythagoras formula:

⇒ (hypotenuse) = \sqrt{(perpendicular)^2+(base)^2}

Plugging the values:

⇒ hypotenuse = \sqrt{5^2+4^2}

⇒ hypotenuse = \sqrt{25+16}

⇒ hypotenuse =\sqrt{41}

⇒ hypotenuse = 6.40  inches

Now we have to find the perimeter :

Perimeter = Summation of length of all sides.

So,

Perimeter  of each triangle = (length + width + hypotenuse)

⇒ Perimeter =(5+4+6.4)

⇒ Perimeter =15.4  inches

Perimeter of each triangle, as they are equally sized are same that is   15.4 inches.

elena-s [515]

Answer:

-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}

Step-by-step explanation:

Given : Expression -1\frac{5}{2}-\frac{7}{12}

To find : Subtract the expression ?

Solution :

Step 1 - Write the expression,

-1\frac{5}{2}-\frac{7}{12}

Step 2 - Write mixed form into proper form,

-1\frac{5}{2}-\frac{7}{12}=-\frac{7}{2}-\frac{7}{12}

Step 3 - Take least common denominator,

-1\frac{5}{2}-\frac{7}{12}=\frac{-42-7}{12}

Step 4 - Solve,

-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}

-1\frac{5}{2}-\frac{7}{12}=\frac{-49}{12}

PLEASE HELP!!! FINDING PROBABILITY MATH!!!
8090 [49]

The probability that a person wins the game is 32.1%

<h3>How to illustrate the probability?</h3>

Based on the information given, the following can be depicted. It should be noted that there are 6 sides as well as 4 cards.

Therefore, the numbers on the dice i.e from 1 - 6 will be represented 4 times each. This gives a total of (4 × 6) = 24. There are also 4 cards. The total in sample space will now be:

= 24 + 4 = 28

The frequency table will be such that 28 or more has a relative frequency of 9. Therefore, the probability that a person wins the game will be:

= 9/28 = 32.1%

When you win 25% of the time, this illustrates that the number of products picked will be:

= 25% × 28

= 7 products.

The probability of participants achieving a winning score of 36 or higher in four consecutive attempts will be:

= 1/6⁴

= 1/1296
