Nataliya [291]

Answer:

Lizzy's recipe is not a proportional relationship with the brownie recipe because of the difference in ratio.

Step-by-step explanation:

Brownie recipe:

Cocoa powder = 3 parts

Flour = 2 parts

Ratio of cocoa powder to flour = 3 : 2

Lizzy's recipe:

Cocoa powder = 1 cup

Flour = 1 cup

Simon has a scale model of the Concorde airplane. The actual length of the Concorde is approximately 200 feet. If the ratio of t

Verizon [17]

The answer is: "40 cm " .
_________________________________________________________
Note:
_________________________________________________________

$\frac{200 ft }{ (x) cm} = \frac{5}{1}$ ;

Solve for "x" (in "cm" ) ;

→ 5x = 200 * 1 ;

→ 5x = 200 ;

Divide each side of the equation by "5" ;
to isolate "x" on one side of the equation; & to solve for "x" ;

→ 5x / 5 = 200 / 5 ;

to get:

→ x = 40 .
___________________________________________________________
The answer is: " 40 cm " .

Option B:

Law of cosine, two sides and the included angle are known.

Solution:

Let us first know the law of cosines and law of sines.

Law of cosine:

If we know the sides a, b and the included angle θ, then we can find the third side c. This is known as the law of cosine.

$c^2=a^2+b^2-2abcos\theta$

Law of sine:

The sides of a triangle are to one another in the same ratio as the sines of their opposite angles.

$$\frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC}$

Given ∠P and the sides r, q are known.

To find the value of p:

Option A: Law of cosines, all sides are known.

It is false by the above definition of law of cosine.

Option B: Law of cosine, two sides and the included angle are known.

It is true by the above definition of law of cosine.

Option C: Law of sines, all sides are known.

It is false, because one angle is given in question.

Option D: Law of sines, two angles and the included side are known.

It is false, because two angles are not given.

Option B is the correct answer.

Hence the answer is "Law of cosine, two sides and the included angle are known".
