evaluate 19 + 6a ÷ 2

Answers

Answer:

19 + 3a

Step-by-step explanation:

19 + 6a ÷ 2

If we want to evaluate this equation, there's really only one step.

We need to divide our 6a by our 2.

1. 19 + 6a ÷ 2 => 19 + 3a

So 19 + 6a evaluated is 19 + 3a.

Triangle ABC is transformed to obtain triangle A'B'C':
A Coordinate grid (plane, graph, whichever one you like to use) with two triangles on it. Triangle ABC and Triangle A'B'C'. Chart below tells you where the points are placed:

ABC / A= (-12, 12) / B= (-9, 6) / C= (-3, 12)
A'B'C' / A'= (4, -4) / B'= (3, -2) / C'= (1, -4)

Which statement is correct for ▲ABC and ▲A'B'C'?
1. ▲ABC ~ ▲A'B'C' because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/3 and then rotating it about the origin by 180 degrees.
2. ▲ABC ~ ▲A'B'C' , because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/4 and then rotating it about the origin by 90 degrees.
3. ▲ABC ~ ▲A'B'C' , because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/4 and then rotating it about the origin by 180 degrees.
4. ▲ABC ~ ▲A'B'C' , because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/6 and then rotating it about the origin by 90 degrees.

Answers

Answer:

1. ▲ABC ~ ▲A'B'C' because ▲A'B'C' is obtained by dilating ▲ABC by a scale factor of 1/3 and then rotating it about the origin by 180 degrees.

Step-by-step explanation:

given;

ABC / A= (-12, 12) / B= (-9, 6) / C= (-3, 12)

A'B'C' / A'= (4, -4) / B'= (3, -2) / C'= (1, -4)

consider line AC = 9

A'C' = 3

ratio is 9/3, so the factor is 1/3

A ladder is 8 meters long. It leans against a wall with one end on the ground 6 meters from the wall. The other end just reaches a windowsill. Calculate the height of the windowsill above the ground. Show your work.

Help

Answers

Answer:

2 meters

Step-by-step explanation:

I really don't know if this is right. It is just a guess:

8-6=2 so the windowsill is 2 meters off the ground because if the ladder is leaning 6 meters out, you have to take 6 meters away from 8, which leaves you with 2 meters.

tell whether x and y are in proportional relationship. explain your reasoning

Answers

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") ... This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Kasie likes to jog every morning before work. She can jog 3 miles in 30 minutes, if she
continues to jog at the same rate, how many miles can she run in 2 hours?

Answers

Answer:

12 miles

Step-by-step explanation:

3 miles per 30 minutes

2 hours is made of 4 30 minutes, so 3 x 4 = 12

Answer:

The answer is 12 miles

Step-by-step explanation:

30 minutes is half an hour.

If 30 minutes is half an hour then, 2 hours is 120 minutes.

3 miles in this problem is 30 minutes, so 120 divided by 30 is 4 and 4x3 is 12.

Explain how you know if an ordered pair is a solution to an equation or not.

PLS HELP ITS URGENT

Answers

To figure out if an ordered pair is a solution to an equation, you could perform a test. Identify the x-value in the ordered pair and plug it into the equation. When you simplify, if the y-value you get is the same as the y-value in the ordered pair, then that ordered pair is indeed a solution to the equation. :)

When Gabriella runs the 400 meter dash, her finishing times are normally distributed with a mean of 79 seconds and a standard deviation of 0.5 seconds. Using the empirical rule, determine the interval of times that represents the middle 95% of her finishing times in the 400 meter race.

Answers

Answer:

(78, 80)

Step-by-step explanation:

Given a normal distribution :

Mean = 79 seconds

Standard deviation = 0.5 seconds

Using the empirical rule :

95% of her finishing times :

According to the empirical rule, 95% represents 2 standard deviations from the mean that is ± 2 standard deviations from the mean score or value.

Hence ;

The interval will be defined as ;

Mean ± 2(standard deviation)

79 ± 2(0.5)

79 ± 1

(79 - 1) ; (79 + 1)

78 ; 80
