Explanation:

Since AE = BE, we know that triangle ABE is isosceles with A = B as the congruent base angles (it might help to rotate the triangle 90 degrees clockwise). The congruent base angles are always opposite the congruent sides of an isosceles triangle.

Focus on triangle ABE. Let's find the missing angle E.

A+B+E = 180

55+55+E = 180

110+E = 180

E = 180-110

E = 70

So angle BEA = 70 degrees

This means angle DEC is also 70 degrees. Angles BEA and DEC are congruent vertical angles.

--------------------

Now focus on triangle DEC. We just found E = 70. The diagram shows D = 34. Use these items to find C

D+E+C = 180

34+70+C = 180

104+C = 180

C = 180-104

C = 76

Angle C is 76 degrees

The total number of sixth-grade students at Escobar Middle School is 400 students

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

Let the total number of students in sixth grade = x

5 % of sixth grade students is = 20 students

So ,

We need to calculate the total 100 % students in the sixth-grade

And ,

10 % of sixth-grade students = 2 x 5 % of sixth grade students

                                               = 2 x 20 students

                                               = 40 students

Now ,

100 % of sixth-grade students x = 10 x 10 % of sixth-grade students

                                                    = 10 x 40 students

                                                    = 400 students

Therefore , there are 400 students

Hence , the total number of sixth-grade students is 400 students

Answer:

The probability is 1/8

Step-by-step explanation:

There are two spinners here, total result on each of the two is 4

Probability of even number of the first

The even numbers are 2 and 4

Probability of an even number is 2/4 = 1/2

For the second spinner

Probability of having a 3 on the second spinner is 1/4

So the probability of an even number on the first and a 3 on the second spinner will be;

1/2 * 1/4 = 1/8

Answer:

A is right

Step-by-step explanation:

The pair of both decimals that represent rational numbers is in option [tex](a)[/tex].

A rational number is a number which is expressed as the ratio of two integers, where as the denominator should not be equal to zero [tex](\neq 0)[/tex] and   are terminating and no-terminating but repeating decimals.

Irrational numbers can not be expressed in the form of fractions and are non-terminating and non-recurring.

We have,

[tex]0.752[/tex] and [tex]0.232323.....[/tex]

In the above given numbers [tex]0.752[/tex] is terminating, so it is a rational number.

And,

[tex]0.232323....[/tex] is non-terminating and repeating number, so it is also a rational number.

So, the pair of option [tex](a)[/tex] i.e. [tex]0.752[/tex] and [tex]0.232323.....[/tex] is the pair of rational number.

Hence, we can say that the pair of both decimals that represent rational numbers is in option [tex](a)[/tex].

Explicación paso a paso:

La ganancia máxima esperada ocurre cuando dU / dx = 0

Dada la función U = - x2 + 500x + 100,000

dU / dx = -2x + 500

Dado que dU / dx = 0

Por lo tanto -2x + 500 = 0

Solución para x;

-2x = -500

x = 500/2

x = 250

Sustituya x = 250 en la función para obtener la máxima ganancia esperada como se muestra;

U = - (250) ^ 2 + 500 (250) + 100.000

U = -62500 + 125000 + 100000

U = 162,500 '

Por lo tanto, la ganancia máxima esperada por las ventas es de 162,500

2. 3.8, or rounded, 3.5

3. 4 batches of brownies

4. 16/9, 1.80, or 1.78

Step-by-step explanation:

1. If you divide 1/4 by 15, that would equal 3.75. Since you can't have partial of a person XD you should round it back to 3.

2. If you divide 1/5 by 19, that would be 3.8.

3. If you divide 2/3 by 6, that would be 4.

4. 1/9 divided by 16 would be 16/9. As a decimal, it would be 1.777778. Rounded, it would be 1.80, or 1.78.

Answer:

The item cost 125.53159 cents per ounce if its sales price is $44.28 per kilograms

Step-by-step explanation:

The sale price of item is $44.28 per kilograms. We need it to convert into cents per ounce.

We know that 1 dollar per kilogram = 2.83495 cents per ounce

So, 44.28 dollars per kilograms = 2.83495 * 44.28 cents per ounce

                                                     = 125.53159 cents per ounce

So, the item cost 125.53159 cents per ounce if its sales price is $44.28 per kilograms

Answer:

y=1/2x-3

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(0-(-4))/(6-(-2))

m=(0+4)/(6+2)

m=4/8=1/2

y-y1=m(x-x1)

y-(-4)=1/2(x-(-2))

y+4=1/2(x+2)

y=1/2x+2/2-4

y=1/2x+1-4

y=1/2x-3
