12-inch-tall boxes are being stacked next to 8-inch-tall boxes.
What is the shortest height at which these two stacks will be the same height?

Answers

Answer:

First, we have to find the LCM of 12 and 8 which would be 24. Since we have to multiply 8 by 3, and 12 by 2, then the shortest height would be two 12-inch boxes, and three 8-inch boxes.

An angle measures 64.8° less than the measure of its complementary angle. What is the measure of each angle?

Answers

Answer:

77.4 degrees and 12.6 degrees

Step-by-step explanation:

Let the angles be x and x - 64.8.

Therefore, on the basis of knowledge that complementary angles add up to 90 degrees :

x + x - 64.8 = 90

2x = 154.8

x = 77.4 degrees

x - 64.8 = 77.4 - 64.8 = 12.6 degrees

Step-by-step explanation:

We use the formula:

[tex] \frac{y₂ -y₁}{x₂ -x₁} [/tex]

plugging in we have

[tex]\frac{ (- 1)-(1)}{(6) -( - 2)} = \frac{ - 2}{8} = - \frac{1}{4} [/tex]

Therefore our slope is -1/4

if 300 people come to the gym on a given day, approximately how many people would you expect to exercise for more than 136 minutes?

Answers

Answer: 120

===========================================================

Explanation:

Add up the numbers in the second column:

4+19+25+32 = 80

There are 80 people being surveyed in the table.

Of those 80 people surveyed, 32 of them exercised for more than 136 minutes.

The probability of selecting someone who exercised for more than 136 minutes is the fraction 32/80 = (16*2)/(16*5) = 2/5

----------

Multiply this probability with the larger sample size of 300 to get

(2/5)*300 = 0.4*300 = 120

We estimate that 120 people would exercise for more than 136 minutes.

Note that 120/300 = 2/5.

sobre un estante se pueden colocar 30 libros de ciencias y 6 lubros de letras o 18 libros de letras y 10 libros de ciencias ¿cuantos libros de letras unicamente se pueden colocar?

Answers

Usando un sistema de ecuaciones vamos a ver que entran 24 libros de letras en el estante.

Cuantos libros de letras se pueden colocar?

Vamos a usar las variables:

x = peso de un libro de ciencias.y = peso de un libro de letras.

Por el texto, podemos saber que el peso maximo que tolera el estante esta dado por el sistema de ecuaciones.

30*x + 6*y = P

10*x + 18*y = P

Podemos igualar esas dos ecuaciones para obtener:

30x + 6y = 10x + 18y

30x - 10x = 18y - 6y

20x = 12y

x = (12/20)*y

Ahora, podemos reemplazar esto en una de las dos ecuaciones, por ejemplo la primera:

30x + 6y = P

30*(12/20)y + 6y = P

(3/2)*12*y + 6y = P

18y + 6y = P

24y = P

Así concluimos que entran 24 libros de letras en el estante.

What is the decimal equivalent to -3 3/12

What is the decimal equivalent to -3 3/12

[tex]\huge\rm{ANSWER:}[/tex]

[tex]\huge \rm{ - 3.25}[/tex]

[tex]\huge\rm{SOLUTION:}[/tex]

To begin, keep in mind that - 3 3/12 is a mixed number, also known as a mixed fraction. It has a valid fraction as well as a complete number.

The following is a list of the numbers in a mixed fraction:

[tex]\huge \rm{ - 3}[/tex] the whole number.

[tex]\huge \rm{ 3}[/tex] the numerator

[tex]\huge \rm{ 12}[/tex] the denominator

Follow these procedures to convert -3 3/12 from a mixed number to a decimal number:

Divide the denominator by the numerator to convert the correct fraction to decimal.

3 ÷ 12 = 0.25

To get the entire number of the mixed fraction, multiply it by this decimal number.

-3 + 0.25 = - 3.25

Therefore, the decimal equivalent to -3 3/12 is -3.25

SAS = side angle side

The order is important because the angles must be between the two congruent sides.

One pair of congruent sides is AC = CE as shown by the single tickmarks.

The congruent angles are the vertical angles BCA and DCE. Vertical angles are always congruent. Note how these angles are sandwiched between the tickmarked sides.

She went to a local pond and collected a large bucket of pond water, then poured 500 milliliters of the pond water into each of two identical glass jars. She viewed a small sample of the pond water under a compound light microscope to verify that the water contained multiple species of microscopic protozoa. She was also able to get a rough count of the organisms in her sample using a special microscope slide.
