Which of the following is the solution set to the inequality −2/5x+14>20?Select one:
A. x < -64
B. x > -64
C. x < -15
D. x > -15

Answers

Answer 1
Answer:

Answer:

its C

Step-by-step explanation:

you do inverse operations so you subtract 14 from 20 which gives you 6 and you divide that by negative two fifths and you get negative fifteen but you flip the sign bc you divided by a negative integer so the answer is C x<-15

Which pair of triangles can be proven congruent by SAS? 2 identical triangles are shown. The triangle is reflected across a line to form the second triangle. 2 identical triangles are shown. The triangle is rotated 90 degrees to form the second triangle. 2 identical triangles are shown. The triangle is reflected across a line and then rotated to form the second triangle. 2 identical triangles are shown. The triangle is rotated up and to the left 90 degrees to form the second triangle.

Answers

Answer:

its the third option

Step-by-step explanation:

the one with 2 rings on the second longest angle 2 lines on longest side one side and 1 line on the shortest side

Final answer:

All the described pairs of triangles that are reflected, rotated, or both, can be proven congruent by the SAS postulate because such rigid transformations preserve the congruency of sides and angles.

Explanation:

To determine which pair of triangles can be proven congruent by the SAS (Side-Angle-Side) postulate, we look for two sides of a triangle and the included angle that are congruent to two sides and the included angle of another triangle. When a triangle is reflected across a line, rotated 90 degrees, or both reflected and rotated, it maintains its size and shape, thus the corresponding sides and angles remain congruent.

A reflection or rotation (including a combination of both) is a type of rigid transformation which preserves the size and shape of figures. Hence, all the given pairs of triangles can be proven congruent to the original triangle through the SAS postulate, as rigid transformations do not alter the congruity of sides and included angles.

Can someone help me solve this please?

Answers

to solve this you would need to create a fraction:

24/30 = ?/180

you would multiply 30 by 6 in order to get 180, and what you do to the denominator you must do to the numerator so you would get:

24/30 = 144/180

therefore your answer would be:   b. 144

Find the velocity of a runner that complete 400 meters in 56 seconds

Answers

Answer:

Step-by-step explanation:

As long as the runner does not change direction, the velocity would be

Formula

d = r*t

r = d/t

Solution

r = 400 m  / 56 s

r = 7.14 m/s

Answer:

The correct answer , velocity = 7.14 m/s

Step-by-step explanation:

Formula:

Velocity = Distance/Time

The common units are km/hr and m/s

It is given that,  a runner that complete 400 meters in 56 seconds

From the given information we get,

Distance = 400 m and time = 56 s

To find the velocity

Velocity = Distance/Time = 400/56 = 7.14 m/s

Therefore the correct answer , velocity = 7.14 m/s

Answers

I think that you would add 120 the amount of times to reach 1 whole which is 1.0 so the answer would be 480
