Step-by-step explanation:
the lengths of any line (side, height,...) in A is twice as long as in B.
now, the area of a triangle is
baseline × height / 2
so, two lines are multiplied. that means the factor 2 gets multiplied in 2 times. and that means the area increases by the factor 2×2 = 4
therefore, the area of A is
40.5 × 4 = 162 cm²
1) A
2)C
Constant is cost that can’t be changed so would be materials.
Coefficient is affected by something else, in this case, number of hours since cost per hour is 30.
Hope this helps!
The main thing you need to know for this question is this conversion:
1 L = 1000 mL , or 1 liter is equal to 1000 milliliters.
So, let's make the entire problem into milliliters:
The carton of milk has 2,500 mL, and Zoe drinks 500 mL a day (250 twice a day).
To find the number of days the bottle will last, you divide the total amount of milk by the amount she drinks per day:
2,500 / 500 = 5 days
Answer:
Step-by-step explanation:
Use Pythagorean theorem,
d² = 4² + 4²
= 16 + 16
d² = 32
d = √32
d = 5.67 units
Step-by-step explanation:
The LKM angle is an enclosed angle. So its size is half the arc facing it.
LKM (angle) = ½ LM (arc)
The LMN angle is a shadow angle. So its size is half the size of the arc facing it.
LMN(angle) = ½ LM(arc)
so:
LKM = LMN
