4 0

Answer:

500

Step-by-step explanation:

First we make an equation to find the score for the bonus round. x is the score for the bonus round .

300 + x = 800

Next we subtract 300 from both sides of the equation

300 - 300 + x = 800 - 300

Which get us

0 + x = 500

x = 500

Her score in the bonus round is 500

Which is bigger square root of 1001 - square root of 1000 or 1/10?
IgorC [24]
Square root of 1001=10.0033
square root of 1000=10
so 10.0033-10=0.0033
1/10=0.1
so, 1/10 is bigger than square root of 1001- square root of 1000

A boat leaves a dock and travels 9 miles due north and 12 miles due west. Find how far the boat is from the dock. Type the corre
adelina 88 [10]

Answer:

15 miles

Step-by-step explanation:

Let's say the dock is at the origin on a coordinate plane and each unit is 1 mile. If the boat travels 9 mile due north, that means that we move up from the origin (0, 0) 9 units to point A (0, 9). Now, this boat moves 12 miles due west, so we will go 12 units to the left of (0, 9) to point B (-12, 9). See the attached drawing (sorry for the crudeness).

Notice that this is a right triangle with legs of 9 and 12. That means the distance from the boat to the dock is just the hypotenuse, so use the Pythagorean Theorem: distance = \sqrt{9^2+12^2} =\sqrt{81+144} =\sqrt{225} =15

Thus, the answer is 15 miles.

Hope this helps!

What is the solution of the following question?<br> x^2+10x+25=12
zalisa [80]
Make equal to 0
minus 12from both sides
x^2+10x+13=0
we can't factor so use quadratic formula

x= \frac{-b+/- \sqrt{b^{2}-4ac} }{2a}
x= \frac{-10+/- \sqrt{10^{2}-4(1)(13)} }{2(1)}
x= \frac{-10+/- \sqrt{100-52} }{2}
x= \frac{-10+/- \sqrt{48} }{2}
x= \frac{-10+/- 4\sqrt{3} }{2}
x= -5+/- 2\sqrt{3}


x= -5+ 2\sqrt{3} or -5- 2\sqrt{3}

aprox
x=-1.5359 or -8.4641
