Answer:

The sum is rational.

Step-by-step explanation:

-3/8 is a rational number (the ratio of 2 integers)

3/5 is a rational number (the ratio of 2 integers)

When you add 2 rational numbers, you get a rational number.

What is the length of the hypotenuse of the right triangle shown<br> 10<br> 17.8<br> 625<br> 5

Butoxors [25]

Answer:

B. 17.8

Step-by-step explanation:

c^2 = 14^2 + 11^2 (Pythagoras theorem)

c^2 = 196 + 121

c^2 = 317

c = √317

c = 17.8

(b)

The 50 degree angle and angle b are vertical angles, which means they are congruent.

The 50 degree angle and angle c are a linear pair, which means that they are supplementary/add up to 180 degrees.

Angles a and c are vertical angles, which means they are congruent.

a = 130

b = 50

c = 130

(c)

The 90 degree angle and angle b are vertical angles, which means they are congruent.

The 50 degree angle and angle c are vertical angles, which means they are congruent.

The 50 degree angle, 90 degree angle, and angle d all form a line, which means that they are supplementary and add up to 180.

Angle d and angle a are vertical angles, which means they are congruent.

a = 40

b = 90

c = 50

d = 40

(e)

The measure of a circle is 360 degrees. These three angles form a circle, so therefore if we add them all up, they will equal 360 degrees.

3a + 4a + 5a = 360

12a = 360

a = 30

(f)

The measure of a circle is 360 degrees. These four angles form a circle, so therefore if we add them all up, they will equal 360 degrees.

3a + 4a + 5a + 6a = 360

18a = 360

a = 20

Hope this helps!! :)

e vertices of a rectangle are R(-5,-5), S(-6,-5),T(-1,1),U(-5,1) a translation maps R to the point (2,-9)

Tema [17]

Answer:

The rule of translation : $(x,y)\rightarrow (x+7,y-4)$

The vertices of image is R'(2,-9), S'(1,-9), T'(6,-3) and U'(2,-3).

Step-by-step explanation:

The vertices of a rectangle are R(-5,-5), S(-6,-5), T(-1,1), U(-5,1).

It is given that a translation maps R to the point (2,-9).

Difference between x-coordinates:

$-5-2=-7$

Difference between y-coordinates:

$-5-(-9)=-5+9=4$

The x-coordinate increased by 7 and y-coordinate decreased by 4. It means the figure shifts 7 units right and 4 units down.

The rule of translation is

$(x,y)\rightarrow (x+7,y-4)$

The vertices of image are

$R(-5,-5)\rightarrow R'(-5+7,-5-4)=R'(2,-9)$

$S(-6,-5)\rightarrow S'(-6+7,-5-4)=S'(1,-9)$

$T(-1,1)\rightarrow T'(-1+7,1-4)=T'(6,-3)$

$U(-5,1)\rightarrow U'(-5+7,1-4)=U'(2,-3)$

Therefore, the vertices of image are R'(2,-9), S'(1,-9), T'(6,-3) and U'(2,-3).
