The required simple interest would be the amount of $7500 if invest $30,000 for 10 years in an account that pays 2.5%.

We have been given data:

Principal (P) = $30,000

Rate of Interest (R) = 2.5% = 2.5/100 = 0.025

Time (T) = 10 years

⇒ Simple interest  = P × R × T

Substitute the value of P, R, and T in the above formula,

⇒ Simple interest  = 30,000 × 2.5% × 10

⇒ Simple interest  = 30,000 × 2.5/100 × 10

⇒ Simple interest  = 30,000 × 0.025 × 10

Apply the multiplication operation, and we get

⇒ Simple interest  = $7,500

Therefore, the required simple interest would be the amount of $7500.

Answer:

Simply interest = $750.00.

Step-by-step explanation:

From the question

Principal = $30,000

Time = 10 years

Rate = 2.5%.

Sample interest = ?

Simple interest is give by the formula

= Principal × Rate ×Time

100

= 30,000 × 2.5 × 10

100

=3000 × 2.5 × 1

Note: hundred use it two zero to cancel one zero of 30,000 and one zero of 10 living 3000 and 1

Simple interest = $750.00

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.

Answer:

[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 5% can be converted to a least-squares fraction by dividing the numerator by the denominator and simplifying. The 5% can be expressed as:

5/100

The fraction can be simplified by dividing the numerator and denominator by their common factor, which in this case is 5.

5/100 simplified is 1/20

In summary, 5% is equivalent to the fraction 1/20 in least terms.

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 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:

Infinitely many solutions

Step-by-step explanation:

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.

Step-by-step explanation:

A: 100/150 = 2/3

B: 72/108 = 2/3

C: 80/132 = 20/33

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.

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.

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

The amount of water that the spherical tank can hold is the volume of the spherical tank. This volume can be found by the formula:

The volume of this spherical tank is therefore :

= 4 / 3 x Pi x 25 feet

Then, to see if it can hold enough water for a swimming pool 50 meters long, 25 meters wide with a constant depth of 2 meters, find the volume of the swimming pool as:

= Length x Width x Depth

= 50 x 25 x 2
