Answer:

A triangles angle always equal to 180 degrees. So if you add up what you already have which is 80+40=120

Ping lives at the corner of 3rd Street and 6th Avenue. Ari lives at the corner of 21st Street and 18th Avenue. There is a gym Tw

mr_godi [17]

Answer: (15th street, 14th Avenue)

Step-by-step explanation:

Given the following :

Ping's residence = (3rd street, 6th Avenue)

Ari's residence = (21st street, 18th Avenue)

Gym location = 2/3 the distance of Ping's residence to Ari's residence

So, distance between Ping's home to Ari's home

Distance = (21st street, 18th Avenue) - (3rd street, 6th Avenue)

Distance = (21 - 3) street, (18 - 6) avenue

Distance between ping and Ari = (18th , 12th )

Gym distance = 2/3 of distance between ping and Ari

Gym distance = 2/3 × (18), 2/3 ×(12)

Gym distance = (12, 8)

Gym location = Ping's location + gym distance

Gym location = (3rd street, 6th Avenue) + (12th street, 8th Avenue)

Gym location = (15th street, 14th Avenue)

Suppose that in a certain chemical process the reaction time y (hr) is related to the temperature (°F) in the chamber in which t

Svetllana [295]

Answer:

The expected change in reaction time for a 1°F increase in temperature is 4.39 hours.

The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.

Step-by-step explanation:

The simple linear regression line is used to determine the changes in the dependent variables when the independent variable is changed.

The general form of the simple linear regression line is:

$y=\alpha +\beta x$

The simple linear regression model for the reaction time of a certain chemical process based on the temperature (°F) in the chamber in which the reaction takes place is:

$y=4.40-0.01\ x$

Here,

<em>y</em> = reaction time (in hours)

<em>x</em> = temperature (°F)

Compute the expected change in reaction time for a 1°F increase in temperature as follows:

$y=4.40-0.01\ (1^{\text{o}})$

$=4.40-0.01\\=4.39\ \text{hours}$

The expected change in reaction time for a 1°F increase in temperature is 4.39 hours.

Compute the expected change in reaction time for a 8°F increase in temperature as follows:

$y=4.40-0.01\ (8^{\text{o}})$

$=4.40-0.08\\=4.32\ \text{hours}$

The expected change in reaction time for a 8°F increase in temperature is 4.32 hours.

An equation written below. 3/4x -4 = -19 what is the solution to the equation?

kogti [31]

Answer:

x=-20

Step-by-step explanation:

3/4x-4=-19

3/4x=-19+4

3/4x=-15

x=-15/(3/4)

x=(-15/1)(4/3)

x=-60/3

x=-20
