27 is very hard to see
28: 0.4=10
4/10=10
10/4 times 10 is 25
There are 25 students in the class
Answer:
1/2
Step-by-step explanation:
Because the solid triangle results in a smaller dashed triangle after the dilation, its scale factor will be a fraction. The length of the top side is 2 on the dashed triangle. It corresponds to the top side of the solid triangle which is 4.
2/4 = 1/2
The scale factor is 1/2 the size.
Answer:
Step-by-step explanation:
We can write the equation of a line in 3 different forms including slope intercept, point-slope, and standard depending on the information we have. We have a point (8,1) and a slope from the equation. We will chose point-slope since we have a point and slope.
Point slope:
in our new equation because it is perpendicular to it. This means we will need to change it into its negative reciprocal which is 
.
We will substitute and 
.
This is the equation of the line perpendicular to the equation given that crosses through (-2,3).
371 is the answer you welcome
Since we know that t = 3.4 you put 3.4 where the t is.
2 (36 - 4 × 3.4) So what you do first is multiply 4 and 3.4 which gives you 13.6
2 (36 - 13.6) then you subtract 36 and 13.6 which gives you 22.4
2 (22.4) then you multiply 2 and 22.4 which is 44.8.
So your answer is 44.8
I hope that helped!
