Please helppp

Answers

I believe it’s 20 seconds
Answer:
20 seconds.

Explanation:
The following data were obtained from the question:
Distance = 10 m
Speed = 0.5 m/s
Time =...?

The speed of an object is simply defined as the distance travelled by the object per unit time. Mathematically, it is expressed as:

Speed = Distance /time

With the above formula, we can obtain the time taken for the ball to travel a distance of 10 m as shown below:
Distance = 10 m
Speed = 0.5 m/s
Time =...?

Speed = Distance /time
0.5 = 10/time
Cross multiply
0.5 × time = 10
Divide both side by 0.5
Time = 10/0.5
Time = 20 secs.

Therefore, it will take 20 seconds for the ball to travel a distance of 10 m.

A zoo collected data on the diving times of turtles. Based on the data, the regression line is j = 0.010 + 2.515x, where x is the time of the dive, in minutes. Based on the regression equation, what is the predicted dive depth in meters at 150 seconds? Give your answer to three decimal places. meter(s) ​

Answers

Answer:

6.298 meters

Step-by-step explanation:

Here, we are told that x is the time of the dive in minutes.

We simply first need to convert 150 seconds to minutes before substitution into the regression formula;

Kindly recall that 60 seconds = 1 minute

So 150 seconds will be 150/60 = 2.5 minutes

We now proceed to substitute into;

j = 0.010 + 2.515(x)

i = 0.010 + 2.515(2.5)

j = 0.010 + 6.2875

j = 6.2975 which go 3 decimal places is 6.298 meters

Using the regression model given, substitution the value of x = 2.5 minutes into the equation, the dive depth obtained ls 6.2975 meters.

Given the regression model :

y = 0.010 + 2.515x

x = time of the dive ; y = dive depth

Converting, x to minutes :

150 seconds = (150 ÷ 60) = 2.5 minutes

The dive depth, y after 150 seconds, can be obtained by substituting the value x = 2.5 into the equation :

y = 0.010 + 2.515(2.5)

y = 0.010 + 6.2875

y = 6.2975

There, the dive depth after 150 seconds will be 6.2975 meters

Answer:

C. Alternate Exterior Angles Theorem

Step-by-step explanation:

I took the test

The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.

From the given figure, lines GN and FH are intersecting by the line segments KL and JM.

What are angles of parallel lines?

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal.

From the given figure, we can see that

∠6 = ∠10 (Corresponding angles are congruent)

∠10 = ∠13 (Vertical angles are congruent)

Now, ∠6 = ∠10 = ∠13

The corresponding angles postulate and the vertical angles theorem are proving ∠6 = ∠13. Therefore, options B and D are correct answer.

You had 23 dollars to spend on 4 avocados. They were very green. After buying them you had 11 dollars. How much did each avocado cost?

Answers

Answer:

$3

Step-by-step explanation:

Because you subtract $23-$11 to get the total you spent on avocados then you divide 12/4 because you bought 4 avocados

Answer:

3 dollars for each avocado.

Step-by-step explanation:

Since you had 23 dollars in the beginning and 11 dollars in the end, subtract to find out how much was used for the avacados.

23-11=12

Next, since you bought 4 avocados, you divide 12 by 4 to find out how much each cost.

12/4=3

Each avocado cost 3 dollars.

You can check by multiplying 3 by 4.

3x4=12

Then, add the 12 dollars spent to the 11 dollars left.

12+11=23 dollars
