Answer:

W = 2 22/27 lb

Step-by-step explanation:

W = (4 2/3 + 3 7/9)/3

W = (14/3 + 34/9)/3

W = (42/9 + 34/9)/3

W = (76/9)/3

W = (76/27)

W = 2 22/27 lb

Answer:

Since i don't know what formula is mentioned. I just used the easiest way to solve :)

Step-by-step explanation:

$(3x^2 + 3)^3 = (3x^2)^3 + 3^3 + 3((3x^2)^2)(3) + 3(3x^2)(3^2)$

$= 27x^6 + 27 + 3(9x^4 \times 3) + 3(3x^2 \times 9)\\\\=27x^6 + 27 + 81x^4 + 81x^2\\\\=27x^6 + 81x^4 + 81x^2 + 27\\\\$

$\int\limits {(3x^2+3)^3} \, dx = \int\limits {27x^6 + 81x^4+81x^2 + 27} \, dx$

$= \frac{27}{7}x^7 + \frac{81}{5}x^5+\frac{81}{3}x^3 + 27x +C\\\\= \frac{27}{7}x^7 + \frac{81}{5}x^5+27x^3 + 27x +C\\\\$

Which piece of additional information can be used to prove △CEA ~ △CDB?

Slav-nsk [51]

Answer-

The correct answer is

∠BDC and ∠AED are right angles

Solution-

In the ΔCEA and ΔCDB,

$m\angle BCD=m\angle ACE$

As this common to both of the triangle.

If ∠BDC and ∠AED are right angles, then $m\angle E=90=m\angle D$

Now as

∠BCD = ∠ACE and ∠BDC = ∠AED,

∠DBC and ∠EAC will be same. (as sum of 3 angles in a triangle is 180°)

Then, ΔCEA ≈ ΔCDB

Therefore, additional information can be used to prove ΔCEA ≈ ΔCDB is ∠BDC and ∠AED are right angles.

Tony has $18 to buy apples and bananas for a fruit salad. Apples cost $2 per pound and bananas cost $1 per pound. Write and grap

nlexa [21]

The inequality to describe the situation is; 2a + 1b <= 18

Since according to the question;

Tony has $18 to buy apples and bananas for a fruit salad.

Apples cost $2 per pound and bananas cost $1 per pound.

Let the number of apples bought be; a

Let the number of bananas bought be; b

Therefore, the inequality to describe the situation is;

2a + 1b <= 18

This means that the cost of the total number of apples and bananas bought by Tony is; less or equal to $18.

Additionally, Two possible combinations of pounds and apples that Tony can buy are;

Tony buys 9 apples and no banana

Tony buys 18 bananas and no apple.
