Answer:
100kcal
10kcal
1kcal
Step-by-step explanation:
Each level you go up, you only get 10% of the total energy
3. y-intercept is when x=0, so 2. Slope is change in y divided by change in x, so 4/3, which rounds to 1.3.
4. the equation: y=mx+d, so substitute m for the slope and d as the y-intercept, so you get y=1.3x+2
5. When you look at the graph, when x=7, then y=80. So the student may get an 80.
Answer:
X=9
Step-by-step explanation:
Well since its a vertical angle, vertical angles are equal Or congruent.
So they equal the same so technically
3x+8=35
Solve
x=9
Y=10°
If we're solving for the ninety degree angle, which I seem to doubt, then if 3x=90 then 2x=60 giving a missing total of 30. 30/3 equals 10
