Sum the total acreage, and multiply by the amount per acre.
$(22\frac{1}{2} + 38\frac{1}{4}) *\frac{4}{5}$ . Simplified, this is 48.6, or $48\frac{3}{5}$

$48\frac{3}{5}$

GarryVolchara [31]

Answer:

(22.74 ; 27.26)

Step-by-step explanation:

The confidence interval relation is stated as :

Mean ± Zcritical * σ/sqrt(n)

Mean = 25

σ = 6

The Zcritical at 95% = 1.96

Hence,

25 ± 1.96 * (6/sqrt(27))

25 ± 1.96 * 1.1547005

Lower boundary :

25 - (1.96 * 1.1547005) = 22.73678702

Upper boundary :

25 + (1.96 * 1.1547005) = 27.26321298

(22.74 ; 27.26)

Answer:

616.6 square cm

Step-by-step explanation:

Area of a regular octagon

$= 2 {a}^{2} (1 + \sqrt{2} ) \\ = 2 \times {12}^{2} (1 + 1.414) \\ = 2 \times 144 \times 2.141 \\ = 288 \times 2.141 \\ = 616.608 \\ = 616.6 \: {cm}^{2}$

Plz help me Which expression is equivalent to 24 + 64? (5 points)

Klio2033 [76]

The answer would be C, because 24+64 equals 88. And if you complete the expression 8(3+8), first solve the equation in the parentheses aka 8+3. Which gets you too 11. And now you multiply 8 by 11, and get 88 as your answer.

Which point on the number line shows the graph of -5/4?

Trava [24]

Answer:

Please see attached image.

Step-by-step explanation:

The best way to find the location of the number line for this point is to use ticks every 1/4 (instead of the standard one unit). See how the number line is subdivided marking ticks every 1/4 (one fourth) of the unit instead of a whole unit in the attached image. That way it is easy to move exactly 5 one fourths to the left of the origin (zero) and place a "dot" in that location (this process is marked with orange arrows in the attached image)
