Answer & Step-by-step explanation:

To multiply two fractions you have to multiply the numerators and the denominators.

1/2 × 5/8 = 5/16

3/5 × 5/9 = 15/45 = 1/3

3/8 × 2/5 = 6/40 = 3/20

to make mixed numbers improper fractions, you have to multiply the denominator by the whole number and then add the numerator to it. So the new number becomes the numerator while the denominator stays as the denominator.

2 3/8 × 16= 19/8 *16/1 = 38

If the numerator of the one fraction is the same as the denominator as the other fraction, they cancel out.

1 4/5 × 5/12 = 9/5 × 5/12 = 9/12

1 2/10 × 5 = 12/10 × 5/1 = 60/10 = 6

Hope this helps!!!

Osian was 1.5 m tall. In the last couple of years,his height has increased by 20%

3241004551 [841]

For this case we must find the current height of Osian. For this, we use the following rule of three:

1.5 m ----------------> 100%

x -----------------------> 120%

From here, we clear the value of x.

We have then:

$x = \frac {120} {100} (1.5)\\x = 1.8 m$

Answer:

The current height of Osian is given by:

$x = 1.8 m$

Answer:

6 inches

Step-by-step explanation:

Formula for surface area of a cylinder:

$SA=2\pi r^{2} +2\pi rh$

Plug in values and solve for the radius:

$180\pi =2\pi r^{2} +2\pi r(9)\\$

Divide both sides by $2\pi$

$90=r^{2} +r(9)$

Subtract 90 from both sides

$0=r^{2} +9r-90$

Use the quadratic equation to find the roots

$x=(-b$ ± $\sqrt{b^2-4ac})*\frac{1}{2a}$ (sorry for formatting, Brainly doesn't

allow equations with ± in them)

$x=\frac{-9+\sqrt{9^2-4*1*90} }{2(1)}$ and $x=\frac{-9-\sqrt{9^2-4*1*90} }{2(1)}$

$x=\frac{(-9+\sqrt{81+360})}{2}$ and $x=\frac{(-9-\sqrt{81+360})}{2}$

$x=\frac{(-9+\sqrt{441})}{2}$ and $x=\frac{(-9-\sqrt{441})}{2}$

$x=\frac{(-9+21)}{2}$ and $x=\frac{(-9-21)}{2}$

$x=\frac{12}{2}$ and $x=\frac{-30}{2}$

$x=6$ and $x=-15$

We can't have a negative radius, so that leaves us with r=6 in.

Solve. x – 6 = 14 – 8 0 12 20 –12

lana [24]

The answer is 12 because first we have to simplify 14-8 to 6 so it will be
x-6=6
Then add 6 to both sides lastly simplify 6+6 to 12
So x=12

Answer:

Step-by-step explanation:

# of ways to succeed: 10*10*10*3*25*25--# of possible plates: 10*10*10*26*26*26----P(exactly one W) = [10^3*3*25^2]/[10^3*26^3] = 3*25^2/26^2 = 1875/17576
