Answer:

  • m∠CJV=90°
  • EV←→⊥KT←→

Step-by-step explanation:

Nothing in the problem statement tells you anything about the directions of lines LK or QT, so you cannot conclude they are parallel. You only know that EV crosses CN and KT at right angles.

EJ ⊥ CN means m∠CJV = 90°, as all angles at the intersection of EJ and CN are 90°.

When ordering a pizza, I can choose one of three toppings (labeled P, S, V) and one of two kinds of crust (labeled #1 and #2). W
Hatshy [7]

Answer:

{P#1, P#2, S#1, S#2, B#1, B#2}

Step-by-step explanation:

There are 3 possible options to chose the toppings i.e. P,S and B

There are 2 possible options for crust i.e #1 and #2

Note that for each selected topping I have two options of the crust. For example, if I select topping P, I can select either crust #1 or crust #2. So, my choices will be:

Either P#1 or P#2. Same goes for topping S and B. For topping S, the two possible selections with crust will be:

S#1 and S#2

And for topping B, the options will be:

B#1 and B#2

Sample space is defined as the collection of all possible outcomes. Here, all possible outcomes are all possible combinations of toppings and crust that we just found. So the sample space for this experiment would be:

{P#1, P#2, S#1, S#2, B#1, B#2}

There are total 6 elements in this sample space.

Answer:

20.28 cm²

Step-by-step explanation:

The rectangle on the bottom is 7 cm by 2 cm.

The semicircle has a diameter of 7 cm - 1 cm - 2 cm = 4 cm

diameter = 4 cm

radius = diameter/2 = 2 cm

total area = area of semicircle + area of rectangle

total area = (1/2)πr² + LW

total area = (1/2)(3.14)(2 cm)(2 cm) + 7 cm × 2 cm

total area = 20.28 cm²

Answer:

1 ) 1 cubic centimeter = 0.000001 cubic meters

2 ) 4 cubic meters = 4000000 centimeters

3 ) 948 cubic meters = 948000 liters

Step-by-step explanation:

1 )

<u>Conversion</u>

1 centimeter = 0.01 meters

1 cubic centimeter

= 0.01 x 0.01 x 0.01

= 0.000001 cubic meters

72 cubic meters

= 72 x 0.000001

= 0.000072 cubic centimeters

2 )

<u>Conversion</u>

1 meter = 100 centimeter

1 cubic meter

= 100 x 100 x 100

= 1000000 cubic centimeters

4 cubic meters

= 4 x 1000000

= 4000000 centimeters

3 )

<u>Conversion</u>

1 cubic meter = 1000 liters

948 cubic meters

= 948 x 1000

= 948000 liters
