The decimal i am thinking of is 3 hundredths less than 3 tenths. What is my decimal

Alinara [238K]

3 hundredths - 3/100

3 tenths - 3/10

3/10 is the same as 30/100

3/100 less than 30/100 is 30/100-3/100 = 27/100

Answer: 27/100

Solve for x 14 x square+7x-6

irina [24]

Answer:

x=0.450765 or x=−0.950765

Step-by-step explanation:

14x² + 7x - 6

→ Find the product, sum and factors

Product = -6

Sum = 7

Factors = No factors

→ Since there are no factors utilise the quadratic formula

$\frac{-b+-\sqrt{b^{2}-4ac } }{2a}$

→ List the values of a, b and c

a = 14

b = 7

c= -6

→ Substitute into the formula

$\frac{-7+-\sqrt{7^{2}-4*14*-6} }{2*14}$

→ Simplify

x=0.450765 or x=−0.950765

Find the leg and hypotenuse.

GalinKa [24]

Answer:

Hypotenuse length is (√2)x if the leg lengths are x and x respectively.

Step-by-step explanation:

This is an isosceles right triangle. The two acute angles are 45 degrees each and the leg lengths can be represented by x. Applying the Pythagorean Theorem, we get x^2 + x^2 = h^2 (where h is the length of the hypotenuse), or

2x^2 = h^2.

Solve this for h. Taking the square root of both sides of this equation, we get:

(√2)x = h

Conclusion: if the two legs of this equilateral right triangle are x and x, respectively, the length of the hypotenuse is h = √2x.
