Answer:
The answer is 164.25.
Step-by-step explanation:
The mean is the "average" of the data set.
1 day use 4 bags
? day use 1/2 bag
Cross multiply
(1•1/2)/4= 1/2•1/4= 1/8 of the day
In 1/8 of the day 1/2 of bag of milk will be used.
Answer:
f(x)= 25(1 + 0.20)^t
Step-by-step explanation:
The formula- <em>f(x)= a(1+r)^x</em>
<em />
a= initial amount (25)
r= growth rate (20%... 0.20)
x= # of times (we don't have that in here)
When you plug in the values, you get
f(x)= 25(1 + 0.20)
hope this helps!!
Answer:
D₁ = 68°
Step-by-step explanation:
If AB = BE then ΔABE is an isosceles triangle, therefore A₁ = E₁.
If A₁ = 28° then E₁ = 28°.
<u>Opposite sides</u> of a parallelogram are <u>parallel</u>.
Using the Alternate Interior Angles Theorem:
A₂ = E₁ = 28°
Therefore, A = A₁ + A₂ = 28° + 28° = 56°
<u>Opposite angles</u> in a parallelogram are <u>equal</u>.
Therefore, C = A = 56°.
<u>Opposite sides</u> of a parallelogram are <u>equal in length</u>, so AB = CD.
If AB = DE = CD then ΔCDE is an isosceles triangle.
Therefore, C = E₃ = 56°.
Interior angles of a triangle sum to 180°.
⇒ D₁ + C + E₃ = 180°
⇒ D₁ + 56° + 56° = 180°
⇒ D₁ + 112° = 180°
⇒ D₁ = 180° - 112°
⇒ D₁ = 68°
11 * 30 = 330
Answer is 330 squared cm's
