Answer:
2.a)11.355 b)0.94625
3. divide 6 by 4
4. 0.8kg, 800g
Step-by-step explanation:
To convert one measurement to another you need to set it up so that the old measurement gets cancelled out when you multiply the conversion ratio.
2a) the gallons on top and bottom get cancelled out leaving you with the measurement that you want
2b)
3)
4)
A nonagon has 9 equal sides, so if the length of one of them is 21, then all of them must be too. The perimeter is 189
Answer:
Step-by-step explanation:
The equation for a circle is , where is the vertex of the circle and is the radius. Immediately, since the center of the circle is given, we know what and are. is 230 and is 220.
The only thing we need to find is the radius, which will just be the distance from the center (230,220) to a point on the circumference (170,170). The distance between them can be calculated using the <u>distance formula</u>, which is really just the <u>Pythagorean Theorem</u> rearranged. The formula states that , where is the change in the x-coordinates of the two points and is the change in the y-coordinates of the two points. Plug-in for 60 and for 50 to get . Solve for , arriving at . Therefore, the radius of the circle is .
Finally, we have all of the components to create the equation of the circle. Plug-in 230 for , 220 for , and for .
The equation of the circle will be .
Hope this helps :)
Answer:
13.5
Step-by-step explanation:
9/2= 4.5 sets of 2 hours
therefore 4.5 x 3 would equal the number of assignments she would complete
4.5 x 3= 13.5
Answer:
9
Step-by-step explanation:
because you know the areais 33.3 so divide 33.3by7.4 and that gives you 4.5 and then multiply 4.5 times 7.4 to give you 33.3 BUT you know you have to divide by 2 to get the area of a triangle so multiply 4.5 times 2 to get you 9.
So 9 times 7.4=66.6/2=33.3
Answer=9
