Answer:

3) D

4) D

5) B

6) B

Step-by-step explanation:

3) A "Pythagorean triple" is a set of 3 integers that could be the sides of a right triangle. The only triangle shown with integer side lengths is choice D.

5) The only triangle for which the square of the hypotenuse is the sum of the squares of the other two sides is choice D.

11² +2² = (5√5)²

121 + 4 = 125

6) The lengths of sides of each right triangle are 2/3 of those of choice D in problem 4. That is, they are a 7-24-25 triangle, multiplied by 2. That means the height is 24·2 = 48, and the area is ...

A = 1/2bh

A = 1/2(28 m)(48 m) = 672 m² . . . . matches choice B

7) The side lengths of a 30-60-90 triangle have the ratios 1 : √3 : 2. That is, the short leg is half the hypotenuse, a fact stated in A and D. Those true statements make it clear that statement B is false.

Change into x + 2y = 6 slope-intercept form.

ikadub [295]

Answer:

y= -1/2x + 3

Step-by-step explanation:

You would subtract x and then rearrange where it would become 2y= -x +6. Then you would divide -x+6 by 2 which would give you the answer y= -1/2x + 3.

7 > −3; Subtract 7 from both sides.<br><br> The resulting inequality is :

luda_lava [24]

Answer:

0 > -10

True

Step-by-step explanation:

7 > -3 Starting with a true statement. This math sentence says, "7 is greater than -3"

7 > -3

-7 -7 Subtract 7.

Working vertically now (from the top, down)

7 > -3

-7 -7

_______

0 > -10

Because 7-7 is 0 on the left side. And

-3-7 is -10 on the right side. This statement is true, because zero is bigger than -10.

How many nanometers are in 1 gigameter

Dmitry_Shevchenko [17]

There are 1* $10^{18}$ nanometers in 1 gigameters.

Given that there is 1 gigameters.

We are required to tell how many nanometers are there in 1 gigameters. Basically we have to convert 1 gigameters into nanometers.

The gigametre (Gm) is basically a unit of length in the International System of Units, defined as $10^{9}$ metres using the SI prefix system.

1 gigameter= $10^{9}$ meters

1 meters=1 gigameters/ $10^{9}$ ----------1

A nanometer is basically a unit of spatial measurement that is $10^{-9}$ meters.

1 nanometers= $10^{-9}$ meters

1 meters=1 nanometers/ $10^{-9}$ --------2

From 1 &2

1gigameters/ $10^{9}$ =1nanometers/ $10^{-9}$

1gigameters= $10^{9}$ / $10^{-9}$ nanometers

1 gigameters= $10^{9+9}$ nanometers

1 gigameters= $10^{18}$ nanometers

Hence there are 1* $10^{18}$ nanometers in 1 gigameters.
