A few boats were traveling upstream and downstream. A satellite recorded the movements of several boats. A motor boat traveled -3.4 miles for every hour in 0.75 hours. How much progress?

Explain plsss

Answers

Answer:

-2.55

if it goes -3.4 miles per hour and it goes for 3/4 of an hour, then -3.4÷4= -0.85 and -0.85•3= -2.55

-255
-3.4 x .75= -2.55
It made -2.55 miles in .75 of a mile or 45 minutes going at a speed of -3.4 mph

A student writes an incorrect step while checking if the sum of the measures of the two remote interior angles of triangle ABC below is equal to the measure of the exterior angle.

In which step did the student first make a mistake and how can it be corrected?
Step 1; it should be m∠m + m∠n + m∠o = 180 degrees (sum of angles in a triangle)
Step 1; it should be m∠m + m∠n + m∠o = 90 degrees (adjacent angles)
Step 2; it should be m∠o + m∠p = 180 degrees (alternate exterior angles)
Step 2; m∠p − m∠o = 90 degrees (alternate interior angles)

Answers

Answer:

Step 1: It should be m∠m + m∠n + m∠o = 180° (sum of angles in a triangle)

Step-by-step explanation:

He made the mistake in Step 1: m∠m + m∠n + m∠p = 180°

It should be m∠m + m∠n + m∠o = 180°

Then only, he can equate it with m∠o + m∠p in step 3.

So, m∠p is the exterior angle and m∠m and m∠n are the two remote interior angles.

m∠o is the adjacent angle to m∠p. They form a linear pair.

Hence, the correct answer is Step 1.

y=−3x−4/3

y=4/3x−3

y=3/4x−3

y=−3x−3/4

Answers

The equation of this line is y= 3/4x - 3
Because the y intercept is -3 and the slope is rise 3 run 4 making it 3/4. It is a increasing line so it has a positive slope

y=3/4x -3. You find the slope which is rise 3 and run 4 so it’s 3/4. Then the y intercept is already given to you since it’s just where the slope crosses the y axis. Y intercept is -3.

blank 6: 85

The complete steps are;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

What is linear expression?

A linear expression is an algebraic statement where each term is either a constant or variable raised to the power one.

We have to given some steps of equation.

Now, The complete steps to solve the equation are;

1/5t + 2 - ____ = 17 - _____

Subtract 2 from both sides;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

Multiply 5 in both sides;

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

So, The complete steps are;

⇒ 1/5t + 2 - 2 = 17 - 2

⇒ 1/5t = 15

⇒ 5 * 1/5t = 5 * 15

⇒ t = 75

For the translation, I believe it would be:
First; a reflection over the Y axis and the new points would be A(4,4) B(2,2) C(2,-1) D(4,1). (The Y value should be the same and the X axis should be the opposite)
Second; It should be moved three units down to get the points that A’ B’ C’ and D’ lie

I *think* they are congruent. I forgot what it exactly means, but they still have the same shape size and have all the same angles.
