Step-by-step explanation:

The students that have both a Netflix and Hulu account is 12.

We can use the principle of inclusion-exclusion to solve this problem. The principle states that if we want to know how many students have either a Netflix or a Hulu account (or both), we can add the number of students who have a Netflix account to the number of students who have a Hulu account and then subtract the number of students who have both.

So, using the information given:

Netflix or Hulu = Netflix + Hulu - (Netflix and Hulu)

87 = 53 + 46 - (Netflix and Hulu)

To find the number of students who have both a Netflix and Hulu account we can solve for (Netflix and Hulu) :

(Netflix and Hulu) = Netflix + Hulu - 87

(Netflix and Hulu) = 53 + 46 - 87

(Netflix and Hulu) = 12

So, 12 students have both a Netflix and Hulu account.

The measures of x and y in the congruent polygons are:

x = 7

y = 8

Congruent polygons are two or more polygons with the same number of sides and the same length for each side. In other words, they are polygons that have the same shape and size.

Two polygons are congruent if and only if it is possible to superimpose one polygon over the other by using a combination of translation, rotation and reflection. Congruent polygons have the same area and perimeter.

Therefore:

m<E = m<A

Substitute the values:

4y - 4 = 28

4y = 28 + 4

4y = 32

4y/4 = 32/4

y = 8

m<F = m<B

The angles which measure 20 degrees are∠1 ,∠5 ,∠7 ,∠9 ,∠11 ,∠14 ,∠16. The solution has been obtained using the properties of parallel lines.

Parallel lines are any two or more lines that lie in the same plane, are equally spaced apart, and never cross one another.

We are given t || x and k || w and m∠3 = 20°

Using the properties of parallel lines, we get -

∠3 = ∠1            (As these are vertically opposite angles)

∠3 = ∠5           (As these are alternate interior angles)                

∠3 = ∠7             (As these are corresponding angles )

Now,

∠4 = 180 - ∠3                     (As they form a linear pair)

∠10 = 180 - ∠9                    (As they form a linear pair)

Also,

∠10 = ∠4                            (Parallelogram's opposite angles are same)

So,

180 - ∠9 = 180 - ∠3

∠3 = ∠9                                                       .... [ii]

∠9 = ∠11               (As these are vertically opposite angles)

∠3 = ∠11               ( from [ii] )                                           .... [iii]

∠11 = ∠14               (As these are alternate interior angles)

∠3 = ∠14               ( from [iii] )                                               .... [iv]

∠14 = ∠16               (As these are vertically opposite angles)

∠3 = ∠16               ( from [iv] )    

Hence, the angles which measure 20 degrees are

∠1 ,∠5 ,∠7 ,∠9 ,∠11 ,∠14 ,∠16.

Answer:

lq= 8

Step-by-step explanation:

because MN is 8 units, lq must also be 8 units.

The inequality that is represented on the given graph is;

y ≥ -2x + c

The general formula for equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, in this question, the coordinate of the y-intercept is (c, 0) and as such, the y-intercept is c.

Ths slope is gotten from two coordinates (2, -3) and (4, -7)

Slope = (-7 - (-3))/(4 - 2)

Slope = -4/2

Slope = -2

Now, the Inequalities that use < or > symbols are plotted with a dashed line to indicate that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to indicate that the line is included in the region.

Also, when we shade above the line, it is greater than and in this case it will be greater than or equal to since the line is a solid line to give the equation; y ≥ -2x + c

Answer:

y = 2/3 x + 7

Step-by-step explanation:

At birth represents the beginning of time for the baby. Lets call this month zero. So here are your coordinates.

x = 0 y = 7 ----> at birth

x = 3 y = 9

x = 6 y = 11

x = 9 y = 13

Now we find the slope between each point. Since the common difference of y is 2 and the common difference in x is 3 , the slope will be

slope = y / x = 2 / 3

Therefore, the equation of the line that represents this relationship is

y = (2/3) x + 7

The angle complementary to an acute angle A is always acute and smaller than 90 degrees, while the angle supplementary to angle A is always larger than 90 degrees, they cannot be equal since they are adding up to 90 degrees and 180 degrees respectively.

A complementary angle is a pair of angles that add up to 90 degrees. Two angles are said to be complementary if the sum of their measures is 90 degrees. The two angles are called complementary angles because they "complete" a right angle.

An angle is considered acute if it measures less than 90 degrees. A complementary angle is an angle that, when added to another angle, will sum up to 90 degrees. So, if angle A is acute, then its complement angle will also be acute.

On the other hand, an angle supplementary to angle A is an angle that, when added to angle A, will sum up to 180 degrees.

So, an angle complementary to an acute angle A is always acute and smaller than 90 degrees, while an angle supplementary to angle A will always be larger than 90 degrees. They can't be equal since they are adding up to 90 degrees and 180 degrees respectively.

For example, if angle A measures 60 degrees, its complementary angle will measure 30 degrees (90 - 60 = 30) and its supplementary angle will measure 120 degrees (180 - 60 = 120).

Each girl scored 9 points

Each boy scored 7 points

Step-by-step explanation:

Let the number of points each girl scored = a

Let the number of points each boy scored = b

7 girls and 6 boys scored a total of 105 points.

7a + 6b = 105......... Equation 1

The difference between the number of points scored by the 7 girls and the number of points scored by the 6 boys is 21

7a - 6b = 21........... Equation 2

7a + 6b = 105......... Equation 1

7a - 6b = 21........... Equation 2

Subtract Equation 2 from Equation 1

12b = 84

b = 84/12

b = 7

Therefore, each boy scored 7 points

7a + 6b = 105......... Equation 1

b = 7

7a+ 6b = 105

7a + 6(7) = 105

7a + 42 = 105

7a = 105 - 42

7a = 63

a = 63/7

a = 9

Therefore, each girl scored 9 points.

The equation of the parabola, in vertex-form, is given as follows:

y = -(x - 6)² + 6.

The equation of a quadratic function, of vertex (h,k), is given by the rule presented as follows:

y = a(x - h)² + k

In which the parameters of the equation are given as follows:

The axis of symmetry is at x = 6, hence:

h = 6.

The maximum height if of 6, hence:

k = 6.

Thus:

y = a(x - 6)² + 6.

The parabola passes through the point (7,5), meaning that when x = 7, y = 5, and thus the leading coefficient a is obtained as follows:

5 = a(7 - 6)² + 6.

a = -1.

Hence the parabola is defined as follows:

y = -(x - 6)² + 6.

[tex]x\ge -7[/tex]

Step-by-step explanation:

The square root function has a domain consisting of numbers greater than or equal to zero. This excludes negative numbers since the square root of a number, when multiplied by the same square root of a number results in the original number: [tex]y=\sqrt{x}\implies y*y=x[/tex]. If we wanted the square root of a negative number, we would need a number which multiplies by it self to get a negative number, but as you may recall, if we square a real number, we always get a positive. So negative numbers are not included in the domain (although there are imaginary solutions)

So we just need the inside of the square root to be greater than or equal to zero. Thus we can derive: [tex]x+7\ge 0[/tex] and then just subtract 7 from both sides to simplify: [tex]x\ge -7[/tex] and now we have our domain in interval notation.

The distance between the centres of the two villages on the map is 16cm. The solution is obtained using the concept of unit conversion.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles. Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.

Now, we are given the scale of a map as 1 : 50000 and that two villages are 8km apart on the map.

The scale of a map is given as 1 : 50000.

=> 1  cm on map  = 50,000 cm  on actual

We know that 1 km = 1,00,000cm

So,

=> 8km  = 8,00,000 cm

So, The distance on the map is

800000 / 50000

= 80/5

= 16 cm

Hence, the actual distance between them is 16cm.

3. What is the equation: y = 400 + x

4. Is the equation additive or multiplicative: Additive

5. I know my answer is correct because: I can use the equation y = 400 + x to calculate the total balance and then double-check my answer using mental math or by subtracting 400 from the total balance to find the amount added (x).

Answer:

Step-by-step explanation:

The ratio of boys to girls in the squad must be no greater than 3:2. This means that for every 3 boys, there must be at least 2 girls.

Since the total number of players in the squad is 14, we can set up the following equation:

3x + 2y = 14

Where x is the number of boys in the squad, and y is the number of girls in the squad.

To find the maximum number of boys that can be selected for the squad, we need to find the highest possible value of x while still satisfying the equation.

We know that x, the number of boys, is a whole number, so we can start testing values of x by subtracting 2 from both sides and then dividing by 3

x = (14 - 2y)/3

If we start testing values for y and substituting it back into the equation, we'll find that the maximum value for y is 6, and the corresponding value for x is 5.

35 + 26 = 15 = 14

Therefore, the maximum number of boys that can be selected for the squad is 5.
