Question 5 options:
76.93 centimeters squared
153.86 centimeters squared
196 centimeters squared
615.44 centimeters squared
Answer:
76.93 cm
Step-by-step explanation:
Since the area of a circle is [tex]\pi r^{2}[/tex], where r is the radius, the area of a semicircle would be half of a circle's area, meaning [tex]\frac{1}{2} \pi r^{2}[/tex]. From the diagram, the semicircle has a diameter of 14cm, and the radius is half of the diameter so r = 14/2 = 7cm.
Plugging in the value for radius r, we get [tex]\frac{1}{2} \pi (7)^{2}[/tex] ≈ [tex]76.9690200129 cm[/tex].
So the right answer is 76.93 cm.

Answer:
y = -127/3 + 1.5
Step-by-step explanation:
Slope intercept form should have both slope and y intercept.
Basically, find two points per table.
so x2-x1/y2-y1
100-36.5/0-1.5 = 63.5/-1.5 = -127/3
Now that we have m in 'y=mx+b', we need b
y intercept is where x = 0, or where the line crosses the y intercept.
y = -127/3x + 1.5

Solve. (USE PEMDAS)
7(6+6) Divided by 4
Answer: 21
Step-by-step explanation: Using PEMDAS you add 6+6 to get 12. Then you multiply 7 and 12 which gets you 84. Then divide 84 by to get you 21.
Answer:
21
Step-by-step explanation:
Using PEMDAS you do the problem In the parentheses first, (6+6) which is 12, then times 7 by 12 which is 84, next divide 84 by 4. Hope this helps you!
Graph the line that contains the point...
We know the slope so substitute the slope first.
[tex]y=-\frac{1}{2}x+b[/tex]
Then substitute the ordered pairs inside the equation.
[tex]-6=-\frac{1}{2}(3)+b\\-6=-\frac{3}{2}+b\\-6+\frac{3}{2}=b \\b=-\frac{9}{2}[/tex]
Graph a line that contains the point ***(3,-6)*** and has a slope of ***-1/2***
The graph below is the "line" that you ask. There's no x = -9 so just plot y = -4.5 and draw.

DUE TOMORROW GIVING BRAINLIEST!
Please define the following terms:
condensation, pressure, temperature, thermal energy..
Answer:
Step-by-step explanation:
condensation=Condensation is the change of the physical state of matter from the gas phase into the liquid phase, and is the reverse of vaporization. The word most often refers to the water cycle
pressure=Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure is the pressure relative to the ambient pressure. Various units are used to express pressure.
tempertuer=Temperature is a physical quantity that expresses hot and cold. It is the manifestation of thermal energy, present in all matter, which is the source of the occurrence of heat, a flow of energy, when a body is in contact with another that is colder. Temperature is measured with a thermometer.
thermal energy=Thermal energy (also called heat energy) is produced when a rise in temperature causes atoms and molecules to move faster and collide with each other. The energy that comes from the temperature of the heated substance is called thermal energy.
