Answer:

16 children

Step-by-step explanation:

80% of 20 children comes out to 16 children who are of age 5.

If desired, rewrite "80%" as "0.80" and use that 0.80 as the multiplier of 20:

0.80(20 children) = 16 children.

Final answer:

By setting up a proportion using the percentage 80% as the decimal 0.80, and cross multiplying with the total number of children in the class (20), we find that the number of children age 5 in the class is 16, corresponding to option E.

Explanation:

To determine the number of children age 5 in a kindergarten class when 80% of the class is that age, and the total number of children is 20, we can set up a proportion. Since 80% of the class is age 5, we can express this as 0.80 (the decimal equivalent of 80%). Therefore:

0.80 (the percentage as a decimal) = Number of children age 5 / Total number of children in the class

0.80 = x / 20

Now, we can solve for x, which represents the number of children age 5, by cross multiplying:

0.80 * 20 = x

16 = x

Therefore, the number of children aged 5 is 16, which corresponds to option E.

Answer:

The students who have a cell phone and can use social media are 3.

Step-by-step explanation:

The question is incomplete so the complete question is:

There are 30 students in Mrs. Bailey’s class, and 1/5 of the class has their own cell phone. Of this group of students, 1/2 of them are allowed to use social media. How many of the students have a cell phone and can use social media?

Now, as given in question we need to find the number of students have a cell phone and can use social media.

Now, to get the number of students of the class who has their own cell phone:

[tex]\frac{1}{5}\ of\ 30.[/tex]

[tex]=\frac{1}{5} \times 30.[/tex]

[tex]=\frac{30}{5}[/tex]

[tex]=6.[/tex]

Of this group of 6 students, 1/2 of them are  allowed to use social media.

So, to get the number of students who use social media:

[tex]\frac{1}{2}\ of\ 6.[/tex]

[tex]=\frac{1}{2} \times 6[/tex]

[tex]=\frac{6}{2}[/tex]

[tex]=3.[/tex]

Therefore, the students who have a cell phone and can use social media are 3.

Answer:

∠ABC = 110°

Step-by-step explanation:

Since Δ BCD is equilateral then the 3 angles are congruent with measure 60°

Thus ∠ DBC = 60°

Δ ABD is isosceles with AB = BC

Thus the base angles are congruent, that is

∠ BAD = ∠ ADB = 65°

Calculate ∠ ABD by subtracting the sum of the base angles from 180°

∠ ABD = 180° - (65 + 65)° = 180° - 130° = 50°

Hence

∠ ABC = ∠ ABD + ∠ DBC = 50° + 60° = 110°

Answer:

110°

Step-by-step explanation:

Triangle ABD is an isosceles triangle.

This means that ∠ ADB is also 65°

Use the Triangle Sum Theorem (All angles of a triangle sum up to 180°)

65 + 65 = 130

180 - 130 = 50

∠ ABD is 50°

For Triangle BCD, all of the sides are the same.

This means all of the angles will be 60° (60° * 3 = 180°)

To find ∠ ABC, you add the two angles

60° + 50° = 110°

Answer:

The interior angle of 12-gon is [tex]150^{\circ}[/tex]  

The exterior angle of 12-gon is [tex]30^{\circ}[/tex]

Step-by-step explanation:

Given as :

A regular 12-gon is a dodecagonal polygon

i.e The number of sides of the polygon = n = 12

Let The exterior angle of 12-gon = x°

And Let The interior angle of 12-gon = y°

Now,

∵ Exterior angle = [tex]\frac{360^{\circ}}{number of sides}[/tex]

So, exterior angle of 12-gon = [tex]\frac{360^{\circ}}{n}[/tex]

Or, x = [tex]\frac{360^{\circ}}{12}[/tex]

∴ x = [tex]30^{\circ}[/tex]

So,The exterior angle of 12-gon = x = [tex]30^{\circ}[/tex]

Again

∵ Interior angle = [tex]180^{\circ}[/tex] - exterior angle

So, interior angle of 12-gon = [tex]180^{\circ}[/tex] - exterior angle

Or, y =  [tex]180^{\circ}[/tex] -  [tex]30^{\circ}[/tex]

∴ y =  [tex]150^{\circ}[/tex]

So,The interior angle of 12-gon = y = [tex]150^{\circ}[/tex]

Hence, The interior angle of 12-gon is [tex]150^{\circ}[/tex] and The exterior angle of 12-gon is [tex]30^{\circ}[/tex] . Answer

285 minutes

Step-by-step explanation:

Well first, how many hours form 7 to 11?

11-7 is 4, thus four hours. Since it is 11:45 and not 11, our answer is 4 hours and 45 minutes. We still need to convert 4 hours to minutes though, to do with we multiply 4 by 60.

4*60=240

Now we add 240 and 45

240+45=285

The answer is 285 minutes.

Investing $2500 annually for 10 years into an annuity with a 3.4% APR yields approximately $31,790.56, making option B the correct choice.

A recurring-payment variable annuity typically involves regular contributions over time, often with variable returns based on market performance. Option B seems to fit this description best: "An annuity with an APR of 3.4% into which you invest $2500 each year."

To calculate the future value of this annuity, we can use the formula for the future value of an annuity:

FV = Pmt × [(1 + r)^n - 1] / r

Where:

FV = Future value

Pmt = Payment per period ($2500)

r = Interest rate per period (3.4% or 0.034)

n = Number of periods (number of years)

Let's assume we invest for 10 years:

[tex]FV = 2500 * [(1 + 0.034)^10 - 1] / 0.034[/tex]

Calculating this gives us approximately $31,790.56.

Therefore, investing $2500 each year for 10 years into an annuity with an APR of 3.4% would result in a future value of approximately $31,790.56.

Final answer: B. An annuity with an APR of 3.4% into which you invest $2500 each year.

The Correct question is:

Which of these is an example of a recurring-payment variable annuity?

A. An annuity with a minimum APR of 3.4% into which you invest a lump sum of $12,500

B. An annuity with an APR of 3.4% into which you invest $2500 each year C. An annuity with a minimum APR of 3.4% into which you invest $2500 each year

D. An annuity with an APR of 3.4% into which you invest a lump sum of $12,500

Answer:

The distance of the object from the base of cliff is 18.24 meters

Step-by-step explanation:

Given as :

The height of the vertical cliff = h = 50 meters

The distance of the object from the base of cliff = x meters

Let The angle of depression of object that level with cliff base = Ф = 70°

Now, from figure

Tan angle = [tex]\dfrac{\textrm perpendicular}{\textrm base}[/tex]

I.e TanФ = [tex]\dfrac{\textrm AB}{\textrm OA}[/tex]

Or, TanФ = [tex]\dfrac{\textrm h}{\textrm x}[/tex]

Or, Tan 70° = [tex]\dfrac{\textrm 50 meters}{\textrm x meters}[/tex]

Or, 2.74 = [tex]\dfrac{\textrm 50}{\textrm x}[/tex]

∴ x =  [tex]\dfrac{\textrm 50}{\textrm 2.74}[/tex]

I,e x = 18.24 meters

So, The distance of the object from the base of cliff = x = 18.24 meters

Hence,The distance of the object from the base of cliff is 18.24 meters Answer

We can determine the distance of the object from the base of the cliff using trigonometry. Specifically, we form an equation using the tangent of the given angle and the known height, solve for the distance, and then substitute the known values to obtain the specific distance.

The subject matter of this question falls in the field of trigonometry as it involves calculating distance using a known height and angle of depression. The object is level with the base of the cliff, and therefore forms a right triangle with the cliff and the sight line from the top of the cliff.

We can use the tangent function to solve this problem. In trigonometry, the tangent of an angle in a right triangle is the opposite side (height) over the adjacent side (distance we're looking for). Given the angle of depression (70°) and the height of the cliff (50 m), we can set up the following equation:

tangent(70°) = height/distance

Moving terms around gives:

distance = height / tangent(70°)

Substituting for height and tangent(70°) we get:

distance = 50 m / tan(70°)

Solving the above equation will give us the distance of the object from the base of the cliff.
