Give your answer in its simplest form.
4(2x - 3y) = y + 5
+

Answers

Answer:

x = 13y + 0.625

Step-by-step explanation:

4(2x - 3y) = y + 5

8x - 12y = y + 5

8x = y + 5 + 12y

8x = 5 + 13y

8x ÷ 8 = 5 + 13y ÷ 8

x = 5 + 13y ÷ 8

x= 13y + 5 ÷8

x = 13y + 0.625

Given the figure below, find the values of x and z.

Answers

Answer: Z = 83

X = 7

Step-by-step explanation:

Z = 83 because the opposite side is also 83 and they are the same angle. X = 7 because the whole thing equals 360 and 83 +83 = 166 and 360 - 166 = 194 and 194 divided by 2 equals 97 and 15 x 7 - 8 = 97 and the other side is also the same because the angles are the same

Which of the following is the best interpretation of the coefficient of determination r2?

About 37% of the variation in arm span is accounted for by the linear relationship formed with the foot length.
About 65% of the variation in foot length is accounted for by the linear relationship formed with the arm span.
About 63% of the variation in arm span is accounted for by the linear relationship formed with the foot length.

a cell phone plan costs $28.90 per month for 400 minutes of talk time. it costs an additional $0.07 per minute for each minute over 400 minutes. to get e-mail access, it costs 10% of the price for 400 minutes of talk time. your bill, which includes e-mail, is the same each month for 8 months. the total cost for all months is $298.56. write and solve an equation to find the number of minutes of talk time you use each month.

Answers

Answer:

Equation = 298.56=6(0.07m+23.90+0.10(23.90))

Minutes = 335

Step-by-step explanation:

Okay, so first simplify to get 298.56=0.52m+172.08

Next subtract to get 0.52m=126.48

Then divide 0.52 to get 335

A group of researchers is designing an experiment to test whether working late at night reduces a person's productivity. The researchers selected a sample of 60 adults, and over the next month, 30 of them will complete assigned tasks late at night whereas the remaining 30 will complete the same tasks during the afternoon. At the end of the month, the researchers will compare the average amount of time it takes each group to complete the tasks. Why is it important that the researchers use randomization to assign each of the adults to a group

Answers

Answer: Randomization prevents the researchers from specifically assigning all adults who regularly stay up late to complete assigned tasks late at night.

-Randomization ensures each group will be similar in everything except the time of day they are assigned to work.

-Randomization prevents the adults from selecting their own group.

Step-by-step explanation:

The options include:

a. Randomization ensures each group will be similar in everything except the time of day they are assigned to work.

b. Randomization prevents the adults from selecting their own group.

c. Randomization eliminates lurking variable from the experiment.

d. Randomization prevents the researchers from specifically assigning all adults who regularly stay up late to complete assigned tasks late at night.

e. Randomization ensures that there'll be an equal number of adults in each group.

Randomization refers to a method that is based on chance alone whereby the participants in a particular study are assigned to treatment group. Based on the information given, it us important that the researchers use randomization to assign each of the adults to a group because:

• Randomization ensures each group will be similar in everything except the time of day they are assigned to work.

• Randomization prevents the researchers from specifically assigning all adults who regularly stay up late to complete assigned tasks late at night.

• Randomization prevents the adults from selecting their own group.

What is a right angle triangle?

A right angle triangle has one of its angles as 90 degrees.

The right angle triangle must obeys the Pythagorean theorem.

c² = a² + b²

where

c = hypotenusea and b are the other legs.

Therefore, the sides that makes a right angle are as follows:

6, 8 , 10 : 6² + 8² = 10²

12, 16, 20 : 12² + 16² = 20²

Un terreno cuadrado tiene una superficie de 900 metros cuadrados. ¿Cuántos metros lineales de alambre se necesitan para cercarlo?

Answers

Respuesta:

120 metros

Explicación paso a paso:

Dado que:

Área del lote cuadrado = 900 m²

Área, A de cuadrado = s²

Donde, s = longitud del lado

s² = 900

Toma el cuadrado de ambos lados

s = raíz cuadrada (900)

s = 30

Se requiere metro lineal de alambre para cercar, el lote será el perímetro del lote cuadrado;

El perímetro del lote cuadrado = 4s

Por eso,

Perímetro del lote cuadrado = 4 * 30

Perímetro del lote cuadrado = 120 m

Studies show that the simple act of petting an animal can decrease levels of stress-producing hormones in the body, which can help to lower blood pressure. Pet ownership also has psychological benefits, such as enhancing feelings of safety, independence, and control, which lead to a greater sense of relaxation. Pets make wonderful companions, but it's also important that owners ensure they have the ability to take care of their animals properly. Pets are often unable to care for themselves and must rely on their owners for food, shelter, and exercise. Owners should consider if they can properly provide a pet with these necessary things before bringing one home. Pets can be both a great joy and a big responsibility. please soon aaaaaaaaaaaaaaaaaaaaaaa Mohammed is x years old.Holly is 3 years older than Mohamed.Karen is twice as old as Mohamed.The total of their ages is 51.
