Answer:
0.015 m²
Step-by-step explanation:
Since we need the area in square meters, we need to first convert our centimeter values into meters.
![\frac{1m}{100cm} =10cm](https://tex.z-dn.net/?f=%5Cfrac%7B1m%7D%7B100cm%7D%20%3D10cm)
1 · 10 = 10
10/100 = 0.1 m
![\frac{1m}{100cm} =15cm](https://tex.z-dn.net/?f=%5Cfrac%7B1m%7D%7B100cm%7D%20%3D15cm)
1 · 15 = 15
15/100 = 0.15 m
The area of a rectangle is a = l · w. Plugging in the given values, we get:
a = 0.1 × 0.15
a = 0.015 m²
hope this helps!
Answer:
$8
Step-by-step explanation:
$40:15 gallons
<u> </u><u> </u><u> </u><u> </u><u> </u><u> </u><u> </u>:3 gallons
So first you say what did you do to 15 to get three?
15÷3= 5
Now you divide forty by five since that is what you did to 15 to get three.
40÷5= 8
The correct answer is C)
![a_n=2\times(-4)^{n-1}](https://tex.z-dn.net/?f=a_n%3D2%5Ctimes%28-4%29%5E%7Bn-1%7D)
.
Since it is a geometric sequence, we multiply by a constant, r, each time to find the next term.
g₂ = -8
g₅ = 512
g₂ * r * r * r = g₅
-8(r)(r)(r) = 512
-8r³ = 512
Divide both sides by -8:
-8r³/-8 = 512/-8
r³ = -64
Take the cubed root of both sides:
∛r³ = ∛-64
r = -4
Now we work backward from g₂ to find g₁:
-8/-4 = 2
We have that g₁ = 2 and r = -4. This gives us
The number of kids in your group is 12.
<u>Step-by-step explanation:</u>
Let the number of kids=x
number of adults=y
total number of people=20
x+y=20(1)
cost of kids ticket=$4
cost of adults' ticket=$6
total cost=$96
4x+6y=96(2)
solving (1) and (2)
we get x=12
y=8
number of adults in the group y=8
number of kids in the group=12
