Answer:

16 / 2, 8

Step-by-step explanation:

Half always means divide by two. 16 divided by 2 is 8. That last sentence is also the equation.

A number divide by 2 equals 16.
n/2 = 16
Do the inverse to find the number. Opposite of division is multiplication.
16 x 2 = 32

This right triangle has one leg with a length of 45 units and a hypotenuse with a length of 75 units. What is the length of the

Nesterboy [21]

The length of other leg is 60 units.

Step-by-step explanation:

Given,

Length of one leg = a = 45 units

Length of other leg = b

Length of hypotenuse = c = 75 units

Using pythagoras theorem

$a^2+b^2=c^2\\(45)^2+b^2=(75)^2\\2025+b^2=5625\\b^2=5625-2025\\b^2=3600$

Taking square root on both sides

$\sqrt{b^2}=\sqrt{3600}\\b=60\ units$

The length of other leg is 60 units.

The time it takes to travel to a destination varies inversely with the average speed. It takes two hours when the average speed

Zolol [24]

Answer:

1 hour

Step-by-step explanation:

The time it takes to travel to a destination varies inversely as its speed

T= k/S

K= TS

Time= 2 hours

Speed= 40mph

K= 2×40

= 80

Therefore if the average speed changes to 80mph then the new travel time can be calculated as follows

T= 80/80

= 1 hour

Hence the new travel time is 1 hour

Select the correct answer.<br> √3<br> 1,53<br> If the point<br> 3 is on the unit circle, what is x?

emmasim [6.3K]

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3. The correct option is D.

<h3>What is the equation of the circle with radius r units, centered at (x,y)?</h3>

If a circle O has a radius of r units length and it has got its center positioned at (h, k) point of the coordinate plane,

then, its equation is given as:

$(x-h)^2 + (y-k)^2 = r^2$

The equation of unit circle is

$(x-h)^2 + (y-k)^2 = 1\\\\x^2 + \dfrac{\sqrt{3} }{3}^2 = 1\\\\x^2 + \dfrac{1 }{3} = 1\\\\\\x^2 = 1 - \dfrac{1 }{3} \\\\x^2 = 2/3\\$

Thus, x = √2/ 3

If the point ( x, √3/ 3) is on the unit circle, then the value of x will be √2/ 3.

The correct option is D.
