Answer:
the first one is false and
the second one is false
Answer:
4) Yes
5) Yes
6) Yes
7) No
Step-by-step explanation:
4) When we look at the table in the question, we can see the pattern is comics x 3 = price.
We know the definition of a proportional relationship is when one number is increased, the other is as well. So, it is in a proportional relationship.
5) We do the same thing here, we notice that we can divide the number of bikes by 5 to get the number of trips.
So, this is a proportional relationship.
6) The same reasoning applies to 6, we can see they follow a pattern.
7) All of them can be multiplied by 2, except the last one can't, so this is NOT a proportional relationship.
Answer:
106°
Step-by-step explanation:
The angle CAB is an inscribed angle of the arc mBC, so we have that:
mBC = 2*CAB
So we have that mBC = 2*37 = 74°
The segment AC is a diameter of the circle, so mAC = 180°
The ? angle is the arc mAB, which is the difference of mAC and mBC, so:
mAB = mAC - mBC = 180 - 74 = 106°
So the ? angle is 106°.
Answer:
y = -2x + 4
Step-by-step explanation:
First find slope:
We know equation of a line is y = mx + b, where m = slope and b = y-intercept, so we can plug in the slope:
y = -2x + b
The y-intercept of the equation is 4 because the coordinate (0, 4) is given. Therefore, the equation is:
y = -2x + 4
Answer:
216 cm²
Step-by-step explanation:
Use the formula for the surface area of a cuboid.
SA = 2lw + 2lh + 2hw
2(6)(3) + 2(6)(10) + 2(10)(3)
36 + 120 + 60
= 216
The surface area of the cuboid is 216 cm².
