Answer:

2.6

Step-by-step explanation:

we know by Pythagoras theorem that

$a^2+b^2=c^2$

so for our triangle we have

$a=6\\\\b=b\\\\c=7\\\\\\\\6^2+b^2=7^2\\\\b^2=7^2-6^2\\\\b^2=(7-6)(7+6)\\\\b^2=1(13)\\\\b=\sqrt{13}\\\\b\approx 2.6$

The answer is a = $\frac{4}{-3}$

Step-by-step explanation:

1. Convert the mixed fraction to an improper fraction

To find the numerator, multiply the denominator by the whole number and add the numerator to it.

The denominator remains the same.

So, 2 $\frac{2}{3}$ will be $\frac{8}{3}$

2. Now the equation is,

$\frac{3}{2}$ a - $\frac{4}{3}$ a = $\frac{10}{3}$ + $\frac{8}{3}$ a

3. Take LCM on both sides.

For the left side, multiply the first fraction by $\frac{3}{3}$ and multiply the second fraction by $\frac{2}{2}$

$\frac{3*3}{2*3}$ a - $\frac{4*3}{3*3}$ a = $\frac{10+8a}{3}$

4. Solve by making a the subject

$\frac{9a-8a}{6}$ = $\frac{10+8a}{3}$

$\frac{a}{6}$ = $\frac{10+8a}{3}$

$\frac{3a}{6}$ =10+8a

$\frac{a}{2}$ = 10 + 8a

a = 2(10 + 8a)

a = 20 + 16a

a-16a = 20

-15a = 20

a = $\frac{20}{-15}$

a = $\frac{4}{-3}$

Therefore, the answer is a = $\frac{4}{-3}$

Which numbers are equivalent to 3/10

Sedbober [7]

Answer:

Multiply numerator and denominator with same number to gwt the answers . There are infinitely many numbers

3/10 × 2/2 = 6/20

3/10 × 5/5 = 15/50

3/10 × 10/10 = 30/100

A bowl contains 25 balls numbered 1 to 25. A ball is drawn and its number is noted. Without replacing the first ball, another ba

Afina-wow [57]

Step-by-step explanation:

n(S) = 25

Assume that O : odd numbers and E : even numbers,

n(O) = 13

n(E) = 25-13 = 12

P(OO) = P(O) x P(O)

= 13/25 x 12/24

(because without replacing so the number of balls left decreases)

= 13/25 x 1/2

= 13/50
