Answer:

2390.7 square meters

Step-by-step explanation:

(semicircle area) 30.5/2 = 15.4

15.4 x 15.4

= 232.5625 x 3.14

= 730.24625 x 2 = 1460.4

(square area) 30.5 x 30.5 = 930.25

930.25+ 1460.4= 2390.7 square meters

you may want to double check the answer however

In this question they've given us the formula and they just want us to plug in the numbers and get the value.


P is the original value, P=$600


r is the depreciation rate, r=10%=0.1


t is the time in years, t=2


A = P(1-r)^t = 600(1 - 0.1)^2 = 600 \cdot .9^2 = 486


Answer: $486

Consider the compound inequality x < 4 and x>a. If a=4 and the compounding word were "or" instead of "and",what would the
FinnZ [79.3K]

Answer:

We have:

x < 4 AND x > a.

if a = 4 and we use an "or" instead of the "and" we have:

x < 4 or x > 4.

This is:

"x is larger than 4 or smaller than 4."

Then the solution of this is all the real numbers except the value x = 4.

The set of solutions can be written as:

{xI x ∈ R  \ [4]}

Where this reads:

"x belongs to the set of the reals minus the number 4".

Or we also could write it as:

x ∈ (-∞, 4) ∪ (4, ∞)

Where we have two open ends in the "4" side, so the value x = 4 does not belong to that set.

The second bags probability is 4 out of 9

All the bags combined the probability is 9 out of 24

Solve 5h + 2(11 - h) = -5 (Find h. Explain each step please.)
pav-90 [236]

Answer:

h = -9

Step-by-step explanation:

Distribute the 2 to the parentheses:

5h + 2(11 - h) = -5

5h + 22 - 2h = -5

Add like terms:

3h + 22 = -5

3h = -27

h = -9
