1

= -20

Step-by-step explanation:

Multiple: 2/

3

* (-6) = 2 · (-6)/

3 · 1

= -12/

3

= -4 · 3/

1 · 3

= -4

Multiply both numerators and denominators. Result fraction keep to lowest possible denominator GCD(-12, 3) = 3.

In words - two thirds multiplied by minus six = minus four.

The triangle above is isosceles and b&gt; a. Which<br> of the following must be FALSE?
kow [346]

If the triangle is isosceles and b is greater than a then,

(c) AC = BC is false.

An isosceles triangle in geometry is one with at least two equal-length sides. It can be defined as having exactly two equal-length sides or as having at least two equal-length sides, with the equilateral triangle being an exception to the second definition.

The triangle is an isosceles triangle and angle b is greater than angle b.

For option (A),

AB = BC, therefore a = c which is possible.

For option (B),

AB = AC, therefore b = c which is also possible.

For option (C),

AC = BC, therefore a =b.

But we have b > a. Hence AB  = BC is false.

For option (D),

a = c, therefore AB = BC which is possible according to the properties of an isosceles triangle.

Option (C) is false.

Megans room was remodeled. The new area of the room is 175% of the previous area. Only the length of the room changed.
Alex17521 [72]

Answer:

As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.

Therefore, the expression become

                                                             \frac{175}{100}\:l\cdot b

                                                             =1.75\:l\cdot b

And the area of Megan's room is increased by 0.75 square meters.

Step-by-step explanation:

  • Let l be the length of the room
  • Let b be the width of the room

So the area of the rectangle will be:

                                                         A=l\cdot \:b

As the statement mentions that the new area of the room is 175%% of the previous area.

So the new area of the room becomes:

                                                                 \frac{175}{100}\:l\cdot b

As only the length of the room changed. It means the length of the room is increased by 175%, because of which the area is increased by 175%.

Therefore, the expression become

                                                             \frac{175}{100}\:l\cdot b

                                                             =1.75\:l\cdot b

also

        \left(1.75\right)l\cdot \:b-\left(1\right)l\cdot \:b

         =0.75\:l\cdot b

so, the area of Megan's room is increased by 0.75 square meters.

Jenny reads 5/8 pages in 2/3 minutes what's the unit rate
LekaFEV [45]

Answer:

15/16 pages in a minute

Step-by-step explanation:

So to make a unit rate, you have to make the denominator 0. So (5/8)/(2/3) is 5/8*3/2 or 15/16. So that would be 15 pages in 16 minutes or 15/16 pages in a minute.
