Hello,

315=1*180+135
180=1*135+45
135=3*45+0
GCF(315,180)=45
180/315=4*45/(7*45)=4/7

if the area of a right isosceles triangle is 128 sq . m, what will be length of the identical side of the triangle

kolezko [41]

Let's see. What is a right isosceles triangle?

A right isosceles triangle is a triangle with one right angle with at least two equal sides. In this case, it would have to be ONLY two because it has a right triangle.

What is the formula for the area of an isosceles triangle?

When y = the identical side lengths of the triangle,

and A = area,

(y × y) ÷ 2 = A

Note: Remember to compute from left to right! :)

We divide by two because when you multiple the two identical sides, you would get a square. However, we're trying to find the right isosceles triangle, and we divide by two.

Now, we can plug-in our values!

(y × y) ÷ 2 = 128

(y × y) = 64

Now, we square root both sides!

y = √64

y = 8

The length of the identical sides of the triangle is 8 meters.

mr.rai sells a watch set for rs2,035 at 10% profit . how much money has he paid to buy the watch also find profit amount

Anna007 [38]

Answer:

paid to buy = 1850

profit = 10%

Step-by-step explanation:

2035 = 110%

1% ~ = 18.5

100% = 1850

2035 - 1850 = 185

185 / 1850 * 100 = 10% profit

2. Determine the prime factorization of each number. a) 95 b) 112 c) 164 d) 150

Shalnov [3]

Answer:

In explanation.

Step-by-step explanation:

A). 95 = 51 × 191 where 5, 19 are prime.

-The prime factors of 96 thus obtained are written as 96 = 2 × 2 × 2 × 2 × 2 × 3 = 25 × 31, where 2 and 3 are the prime numbers.

B). 112 = Dividing 112 by 56, we get 112 ÷ 56 = 2. Thus the prime factorization of 112 = 2 x 2 x 2 x 2 x 7 is obtained by writing the factor tree of 112.

-112 is a composite number. 112 = 1 x 112, 2 x 56, 4 x 28, 7 x 16, or 8 x 14.

-Factors of 112: 1, 2, 4, 7, 8, 14, 16, 28, 56, 112.

-Prime factorization: 112 = 2 x 2 x 2 x 2 x 7, which can also be written 112 = 2⁴ x 7.

C). 164 = The prime factorization of 164 can be written as 22 × 411 where 2, 41 are prime.

-The prime factors of 165 are 3, 5, 11. Therefore, the product of prime factors = 3 × 5 × 11 = 165.

D). 150 = Prime Factorization of 150: 2 × 3 × 52

-The prime factorization of 150 is 2 x 3 x 5 x 5 = 2 x 3 × 52 where 2, 3, and 5 are the prime numbers.

The rectangular pool is 45 feet x 18 feet. The fence needs to be 5 ft away from the edges of the pool or a 5 ft border. How many

Mama L [17]

Answer:

The length of fencing is 146 feet.

Step-by-step explanation:

The length of fencing is equal to the perimeter of the rectangle plus 8 times the width of the border between the edge of the pool and the fence. By Geometry, we find that the perimeter ( $p$ ), measured in feet, is equal to:

$p = 2\cdot (w+f)+2\cdot (l+f)$ (1)

Where:

$w$ - Width of the pool, measured in feet.

$l$ - Length of the pool, measured in feet.

$f$ - Width of the border, measured in feet.

If we know that $w = 45\,ft$ , $l = 18\,ft$ and $f = 5\,ft$ , then the length needed of fencing is:

$p = 2\cdot (45\,ft+5\,ft)+2\cdot (18\,ft+5\,ft)$

$p = 146\,ft$

The length of fencing is 146 feet.
