The question is incomplete:

Keith and Michelle went out to dinner. The total cost of the meal, including the tip, came to $53.70. If the combined tip came out to $9.60, and each friend spent an equal amount, how much did each friend pay not including the tip?

Answer:

Each friend paid $22.05 without including the tip.

Step-by-step explanation:

Since you know the total cost of the meal including the tip and the value of the combined tip, you can subtract the amount of the tip from the total cost and divide the result by 2 as they spent an equal amount:

$53.70-$9.60=$44.1

$44.1/2=$22.05

According to this, the answer is that each friend paid $22.05 without including the tip.

Solve the triangle.
Zolol [24]

∠A = 106.3°, ∠B = 20.6°, ∠C = 53.1°

<u>Step-by-step explanation:</u>

In a ΔABC, the sides opposite to the angle A is a, angle B is b, and angle C is c. a = 60 , b= 22, c = 50

We can find any one angle by cosine rule,

a² = b² + c² - 2 bc cos (A)

60² = 22² + 50² - 2(22)(50) cos A

3600 = 484 + 2500 - 2200 cos A

3600 = 2984 - 2200 cos A

3600 - 2984 = -2200 cos A

616 = -2200 cos A

cos A = 616/ -2200 = -0.28

A = cos⁻¹ (-0.28) = 106.3°

Now we can use sine rule to find angle B as,

sin A/ a = sin B / b

sin  106.3° / 60 = sin B / 22

sin B = 22 × sin  106.3° / 60

 B = sin⁻¹ (22 × sin  106.3° / 60 ) = 20.6°

As we know the sum of angles in a triangle is 180°.

∠A + ∠B + ∠C = 180°

106.3° + 20.6° + ∠C = 180°

126.9° + ∠C = 180°

∠C = 180° - 126.9° = 53.1°

Answer:

Line z2 : Point L

Line z1 : Point A

Step-by-step explanation:

To find the complex conjugate you flip the sign of the complex number but keep the same magnitudes.

For line z2 we can see that one of the points is 6-7i. To find the complex conjugate we just flip the sign. So the complex conjugate is 6+7i.

This means that the complex conjugate of line z2 can be represented with point: L

For line z1 we do the same thing. 1-2i goes to 1+2i. This can be represented with the point A

The variable Z is directly proportional to X. When X is 5, Z has the value 55.
Mashutka [201]
Z is directly proportional to x, that means :
z = k.x, with k is the coefficient of proportionality:
Let calculate k:
When x = 5, z = 55. Plug in:
 55 = k.5  → k=55/5 ; k =11
The value of z when  = 12 is : z= kx; z = 11(12) and z = 132

Solve the proportion 9/2 = 27/2y
dalvyx [7]

Answer:

y = 3

Step-by-step explanation:

We need to solve the below proportion in this problem,

\dfrac{9}{2}=\dfrac{27}{2y}

First of all, we cross multiply both sides such that,

9\times 2y=27\times 2\\\\18y=27\times 2

Dividing both sides by 18.

y=\dfrac{27\times 2}{18}\\\\y=3

For the above proportion, we find that the value of y is equal to 3.
