Answer:

\sqrt{(6 \times 6 }   +  \sqrt{7 \times 7}  \\  =  \sqrt{ {6}^{2} }  +  \sqrt{ {7}^{2} }  \\  =  { ({6}^{2} )}^{ \frac{1}{2} }  +  { {(7}^{2} )}^{ \frac{1}{2} }  \\  = 6 + 7 \\  = 13

Please show me the steps of doing this question if you know how, ty.
dolphi86 [110]

The arc length is the product of the angle measure in radians and the radius.

... s = r·θ

So, the angle in radians is the ratio of arc length to radius.

... θ = s/r

To convert from radians to degrees, multiply by the conversion factor 180°/(π radians).

... y = s/r·(180°/π)

Then the angle is between

... 15/20·180/π ≈ 42.97

and

... 16/20·180/π ≈ 45.84

Suitable integers in this range are 43, 44, and 45.

One possible integer value of y is 44.

Last week Macy ran 4 times as many miles as Jackson. They ran a total of 20 miles. How many miles did Macy run? how many morr mi
WITCHER [35]
Macy 5 miles because she ran 4 times more than Jackson in relation to Jackson ran 5 mile, this problem can oftenly be seen as
j = 20 \div 4
which would end up in the answer being 5 which is the right answer while someone else can see it as
j = 20 - 4
which would equal 16 which is incorrect because the problem didn't say that Jackson ran one mile nor 4 miles which would be 4*4 or 16 when the correct answer is 20/4=5 because 4*5=20

What are the solutions of the quadratic equation <br> X2+11x=-28
Slav-nsk [51]
X² <span>+ 11x = -28
to find the solution of this polynomial, it'll be easiest to try and factor it. the first thing you need to do is move everything to one side:

</span>x² + 11x = -28 ... add 28
x² + 11x + 28 = 0 ... factor
(x + 7)(x + 4) = 0 ... now set both of your factors equal to zero and solve for x

x + 7 = 0
x = -7

x + 4 = 0
x = -4
