Jeff and Kirk can build a 75-ft retaining wall together in 4 hours. Because Jeff has more experience, he could build the wall

oee [108]

It will take Kirk about 8 hours 32 minutes to build the wall by himself.

<h3>What is Quadratic Polynomial?</h3>

Quadratic equations are second-degree algebraic expressions and are of the form ax² + bx + c = 0.

Here, Let k represent Kirk's time (in hours) to build the wall by himself. Then (k-1) is the time it takes for Jeff to build it. Their working-together rate in "walls per hour" is ...

1/k +1/(k -1) = 1/4

Multiplying by 4k(k-1), we have ...

4(k-1) +4k = k(k -1)

k² -9k = -4 . . . . . . . . subtract 8k and simplify

k² -9k +20.25 = 16.25 . . . . . add (9/2)² to complete the square

k -4.5 = √16.25 . . . . . . . . . take the square root

k = 4.5 +√16.25 ≈ 8.531129 . . . hours

The fractional hour is ...

0.531129 × 60 min ≈ 31.9 min ≈ 32 min

Thus, It will take Kirk about 8 hours 32 minutes to build the wall by himself.

Find the sum of 7a³ + 14a + 12 and -6a³ + 12a² -7

maw [93]

Answer: $a^3+12a^2+14a+5$

Step-by-step explanation:

$7a^3+14a+12+(-6a^3+12a^2-7)$

$7a^3+14a+12-6a^3+12a^2-7\\a^3+12a^2+14a+5$

Answer:

a) = 4.5

b) = 3.3

Step-by-step explanation:

Before solving our problems given to us let us under stand the rule of cube roots

It says $\sqrt[3]{x \times x \times x} = x$ -----(A)

Also

$\sqrt[3]{x \times x \times x \times y \times y \times y} = x \times y$ ---(B)

Now let us see each part one by one

a) we have

$\sqrt[3]{64} + \sqrt[3]{0.027} + \sqrt[3]{0.008}$

Now 64 = 4 x 4 x 4

0.027 = 0.3 x 0.3 x 0.3

0.008 = 0.2 x 0.2 x 0.2

substituting these values

$\sqrt[3]{4 \times 4 \times 4} + \sqrt[3]{0.3 \times 0.3 \times 0.3} + \sqrt[3]{0.2 \times 0.2 \times 0.2}$

Applying Rule A in above

$=4+0.3+0.2$

$=4+0.5$

4.5

b) we have $\sqrt[3]{0.3 \times 0.3 \times 0.3 \times 11 \times 11 \times 11}$

Applying the B rule in this

$=0.3 \times 11$
