andriy [413]

Answer:

box 1: monomial

box 2: binomial

Step-by-step explanation:

reasoning: Box 1’s volume is modeled by a monomial times a monomial, so it will be a monomial.

Box 2’s volume is modeled by a monomial times a binomial, so it will be a binomial.

How do I use the cosine rule for these problems?

Elenna [48]

Answer:

see explanation

Step-by-step explanation:

Using the Cosine rule

a² = b² + c² - 2abcosA ← Rearranging for cosA gives

cosA = $\frac{b^2+c^2-a^2}{2ab}$

(a)

let a = 10, b = 7, c = 8 and A = α, then

cosα = $\frac{7^2+8^2-10^2}{2(7)(8)}$ = $\frac{49+64-100}{112}$ = $\frac{13}{112}$ , thus

α = $cos^{-1}$ ( $\frac{13}{112}$ ) ≈ 83° ( to the nearest degree )

(b)

let the angle opposite side 7 be x

Using the Sine rule

$\frac{10}{sin83}$ = $\frac{7}{sinx}$ ( cross- multiply )

10sinx = 7sin83 ( divide both sides by 10 )

sinx = $\frac{7sin83}{10}$ , thus

x = $sin^{-1}$ ( $\frac{7sin83}{10}$ ) = 44°

The third angle can be found using the sum of angles in a triangle

third angle = 180° - (83 + 44)° = 180° - 127° = 53°

The 3 angles are 83°, 44°, 53°

if one angle of parallelogram is four times greater than the othe. find of a parallelogram? *Short ans please*

enyata [817]

Answer:

144°, 144°, 36°, 36°.

Step-by-step explanation:

Take shorter angle = x

Then the bigger angle = 4x (4 times the other angle)

In a parallelogram, there are 4 angles. Also, in a parallelogram opposite angles are equal to each other.

So,

1 angle = x

2 angle = 4x

3 angle = x

4 angle = 4x

The sum of all 4 angles in a parallelogram = 360°. So,

4x + x + 4x + x = 360°

10x = 360°

x = 360/10

x° = 36°

4x = 36 × 4 = 144°

Angles in the parallelogram = 144°, 144°, 36°, 36°.

Hope it helps ⚜

A small bag of trail mix contains 3 cups of dried fruit and 4 cups of almonds. A large bag contains 4 1/2 cups of dried fruit an

Nesterboy [21]

Answer:

The system don't have a unique solution

Step-by-step explanation:

We define the problem in different variables:

Dried Fruit is going to be x

Almonds are going to be y

So, in this new terms we have that a small bag (S) and a large bag ( L) are going to be represented by:

3x+4y=S
4 $\frac{1}{2}$ x+6y=L

If we multiply both sides of the first equation by 1.5 we got this:

4 $\frac{1}{2}$ x+6y=1.5S
4 $\frac{1}{2}$ x+6y=L

Therefore we can notice that the system of equations has an unlimited number of soltions because is a consistent and dependent system.
