The total cost of the meal is 66.045

Given,

The cost of the meal = 64.75

The discount given on that day = 15%

The tip given by Zurn family = 20%

We have to find the total cost of the meal.

First we have to find the total cost including tip before discount is added.

That is,

120% of 64.75

= 64.75 × 120/100

= 6.475 × 12

= 77.7

Here, the total cost including tips before discount is 77.7

Now, we have to deduct the discount.

100 - 15 = 85

That is,

85% of 77.7 will be the total cost of the meal

= 77.7 × 85/100

= 6604.5 / 100

= 66.045

Therefore, the total cost of the meal is 66.045

Answer: A

180-130= <D

50=<D

50+70= 120

180-120=<B

60=<B

m<BCD= 70

m<DBC= 60

70-60=10

Answer:

О A = 10°

Step-by-step explanation:

∡ DBC = 180 - 130 = 50°

∡ DBC + ∡ CBD + ∡ BCD = 180°

50° + 70° + ∡BCD = 180°

∡BCD = 180° - (50°+70°)

∡BCD = 180° - 120°

∡BCD = 60°

Then:

∡BCD - ∡DBC = 60° - 50° = 10°

We know that the three trigonometric ratios of a right angle triangle are given as;

sin θ = opposite/hypotenuse

cos θ = Adjacent/hypotenuse

tan θ = Opposite/Adjacent

Now, from the right angle triangle given to us, if we want to consider the angle C, then we will have the trigonometric ratios as;

sin C = a/b

Answer:

Proved.

Step-by-step explanation:

l // m and p is transversal.

    ∠1 ≅ ∠3   ----------(I)   {Corresponding angles}

p // q and l is transversal.

   ∠3 ≅ ∠2   -------(II) {Corresponding angles}

From (I) & (II),

      ∠1 ≅ ∠2

Hence proved.

To prove ∠1 = ∠2

In a plane, parallel lines are those whose distances between them are constant. Lines that are parallel never cross. Lines that cross at a straight angle (90 degrees) are said to be perpendicular.

Given: l II m and p II q

According to the properties of parallel lines

∠1 and ∠ 3 are equal because l II m therefore ∠1 and ∠ 3 are corresponding angles.

Since  p II q therefore ∠3 = ∠2 { angles present on the same sides of the parallel lines called corresponding angles are equal }.

Thus since ∠1= ∠3 and ∠3=∠2 therefore we can say that ∠1 = ∠2.

Hence proved.

Check the picture below.

Taking into account the definition of vertex form, the quadratic function y=x² +2x-12 in vertex form is f(x) = 1(x - +1)² -13

The function f(x) = ax²+ bx + c with a, b, c real numbers and a ≠ 0, is a quadratic function expressed in its polynomial form.

The graph of a quadratic function is a curve called a parabola.

Every quadratic function can be expressed by f(x) = a(x - h)² + k

where

The value of -b÷(2a) indicates the value of x or h and replacing this value into the function, you get the value of y or k of the vertex of the function.

In this case, the quadratic equation y=x² +2x-12, where:

The value of x or h of the vertex is calculated as -2÷(2×1)

Solving: -2÷2= -1

The value of y or k of the vertex of the function is calculated as y=(-1)²+2×(-1) -12

Solving y= -13

Finally, the quadratic function can be expressed in vertex form by f(x) = 1(x - +1)² -13

The average change in the temperature per hour is -1.5°F.

Average:

Average means a single number taken as representative of a list of numbers, usually the sum of the numbers divided by how many numbers are in the list.

Given,

On a cold day, the temperature in a certain city changed −14.4°F over 9.6 hours.

Here we need to find the average change in temperature per hour.

To find the average temperature we have to divide the given two temperature.

Temperature change in 9.6 hour = -14.4°F

So, the average change is calculated as,

=> temperature / hour

=> -14.4 / 9.6

=> -1.5°F

Therefore, the average change in temperature is -1.5°F per hour.

Answer: the number of teachers are 14.4 and the amount of students that don’t own laptops of 5400

Step-by-step explanation:

The size of the angle marked t is 60 degrees.

We are given an isosceles triangle with one angle as 30 degrees.

We have to find the angle marked t.

Let us name the triangle.

Let the vertex formed by the intersection of two equal sides be A and,

The vertex with 30 degree angle be B and the third vertex be C.

We know that,

AB = AC

Hence,

∠ ABC = ∠ ACB = 30 degrees.

Hence, ∠ BAC =  180 - 30 - 30 = 120 degrees

We know that,

t + ∠ BAC = 180 degrees (supplementary angles)

Hence,

t + 120 = 180

t = 180 - 120

t = 60 degrees

Answer: v = 8, 5; The sum of these values would be 13.

∣2v − 13∣ + 6 = 9

Combine like terms, utilizing the properties of equality. Do not forget to follow the order of operations!

∣2v − 13∣ + 6 = 9

Subtract 6 from both sides of the equation.

∣2v − 13∣ = 3

Consider the definition of absolute value (distance from the number zero); the absolute value of x and -x would both be x.

2v − 13 = 3

2v − 13 = −3

Add 13 to both sides of the equation.

2v = 16

2v = 10

Divide both sides of the equation by 2.

v = 8

v = 5

Add the sum of the values.

8 + 5 = 13

The number of hours it would take Ganymede to complete a full rotation is 171.25 hours.

The first step is to convert days to hours. A day is equivalent to 24 hours. In order to convert days to hours, multiply 7 by 24.

Multiplication is the mathematical operation that is used to determine the product of two or more numbers.

1 day = 24 hours

24 x 7 = 168 hours

The second step is to convert minutes to hours, In order to do this, divide 15 by 60. Division is the process that is used to determine the quotient of two or more numbers.

60 minutes = 1 hour

15 / 60 = 0.25 hours

Now, add all the converted hours together. Addition is the mathematical operation that is used to determine the sum of two or more numbers.

Total hours = 168 hours + 3 hours + 0.25 hours = 171.25 hours
