Step-by-step explanation:

i don't know how to explain but this is pretty much how you'd do it

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.

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 surface area of the cylinder is 1733.28 square inches

The area of a shape is the amount of space on the shape

For most regular quadrilaterals, you multiply the side lengths to determine the area

The shape is given as

Shape = cylinder

Also, we have

Radius, r = 12 inches/2

r = 6 inches

Height, h = 40 inches

The surface area of the cylinder is calculated as

SA = 2πr² + 2πrh

So, we have:

SA = 2 * 3.14 * 6² + 2 * 3.14 * 6 * 40

Evaluate

SA = 1733.28 square inches

Hence, the area is 1733.28 square inches

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 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: A

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°

Answer: 5/3

Step-by-step explanation:

The scale factor is the same as the ratio of the length of a side of the image to the length of the corresponding side in the preimage.

We know that N'Q'=10 and NQ=6, so the scale factor is 10/6 = 5/3.

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

Answer:

16,25 Pa

Step-by-step explanation:

P=F/A;

650/40 = 16,

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

The graph of the linear equation, y = -3x - 2, that passes through (-2, 4) is shown in the attachment below.

The linear equation of a line is expressed in slope-intercept form as y = mx + b. The y-intercept of the line, which is the point where the line intercepts the y-axis, is represented as "b" in the equation.

The slope is represented as "m".

Given that the line, y = -3x + b passes through the point A(-2, 4), find the value of the y-intercept of the line, b, by substituting x = -2 and y = 4 into y = -3x + b:

4 = -3(-2) + b

4 = 6 + b

4 - 6 = 6 + b - 6

-2 = b

b = -2

Substitute b = -2 into the equation:

What is Percentage?

A relative value indicating hundredth part of any quantity is called percentage.

Given that;

The conditions is,

Luis read 75% more pages than Dayja, and Dayja read 75% more pages than Michael.

Total pages read by Dayja = 84

Now,

Since,  Luis read 75% more pages than Dayja.

So, The pages for Luis = 75% of 84

                                   = 75/100 × 84

                                   = 6,300 / 100

                                   = 63

Thus, Pages for Luis = 84 + 63

                                 = 147

And, Number of pages read by Michael = 84 - 63

                                                              = 21

Thus,  Number of pages read by Michael = 21

So, Total number of pages read by Luis, Dayja and Michael all together is;

= 84 + 147 + 21

= 252

By using the method subtraction,

1 quarter is 0.25

1 nickel is 0.05

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given that,

Isaac has 18 coins, all quarters and nickels.

The total value of the coins it $3.50.

Let the quarters be x and nickels be y

x+ y= 18

x= 18 - y... equation 1

1 quarter is 0.25

1 nickel is 0.05

So,

0.25x+ 0.05y= 3.50

substitute x value in above equation

0.25(18-y)+0.05 = 3.50

4.5-0.25y+ 0.05 = 3.50

4.55 - 3.50 = 0.25y

1.05= 0.25y

y= 4.2

y in equation 1

x= 18 - y

x= 18-4.2

x= 13.8
