Answer:
therefore m=-3•5
Step-by-step explanation:
-39=18+4m
collect like terms
4m=18-39
4m=-14
divide both sides by 4m
m= -3•5
Answer:
mean = 5.4
median = 5
mode = is the number that appears the most answer = 5
Step-by-step explanation:
mean
5+6+6+9+10+4+2+5+7+6+7+3+5+5+5+4+9+2+10 = ......... / 19 = 5.4
median
2 2 3 4 4 5 5 5 5 5 6 6 6 7 7 9 9 10 10 then find the middle between these = 5
Hello!
A figure only becomes bigger if it is dilated. This figure is reflected, not dilated, so A is not the answer.
Shapes are similar if the ratios of their corresponding side lengths match. Basically, they are the same shape but can be in a different size or direction. In our case each side is the same length, and they are both triangles. Therefore these shapes ARE similar, so be could be the answer.
If you were to rotate the two triangles and look at the angles that were in the same spot, those are corresponding angles. They would have the same angle measure. If you were to turn each triangle tip pointing up, (S,R') would have the same angle measure, along with (R, S') and (T,T'). As you can see, R is equal to S', so C could also be the answer.
In D we can see that R corresponds to S', not T, so D is not the answer.
Now we are torn in between B and C. C is just explaining one angle. B is saying that the shapes are similar. This would mean that all of their corresponding angles. C is just an example of B. B has it all in one. Therefore, our answer is B) <span>Figure RST is similar to figure R′S′T′.
I hope this helps!</span>
To find percentages, simply take the number that is not the "100%" number and divide it by the other number.
in this case,
52 / 130
complicated way of figuring it out if it makes more sense for you,
find how much is 1% of 130
130/100= 1.3
1% of 130 = 1.3
and then you just take 52 / 1.3
feel free to comment any questions on how to figure out future problems
Answer:
Im positive that u wrote the formula wrong, theres no dot on a formula. What I understand on how to count each molecules is by the following
1) The coefficient in front of the molecules serves a type of multiplier, lets say 3 CO2, you take the 3 and multiply to each atom, so it would be 3 C and with O you do 3x2 cause 2 oxygen atom and it would become 6 O.
2) For the bracket lets say (CH3)2, Its the same thing as coefficient, the subscript 2 serves as a mulitplier, so there would br 2 C and 6 H
3) What happens if you have both the coefficient and subscript. Well, lets take an example of 2(NH3)2, you multiply everything together. So by doing the example, N would be 2 x 1( because theres 1 N) x 2( this being the subscript), which would be 4 N. For H, its 2 x 3(Because theres 3 H atoms) x 2(this being the subscript), which is equals to 12 H atoms.
Hope I didnt confuse you that much and asnwered your questipn, good luck in your future test. : )
