Midpoint between m and r

1 answer:

8 0

The midpoint between m and r would be the difference between the two divided by 2 and then added to the lower number... For example the midpoint between 10 and 30 would be the difference between them (30 - 10 = 20) and divide it by 2 (20/2 = 10) and then add it to the number you started with (10 + 10 = 20). 20 is the midpoint.

So the midpoint between m and r would be..

(r - m) /2 + m

Answer:

S1548.

Step-by-step explanation:

1-7% =- 0.017 and 5.3% - 0.053.

Kevin : After 1 year he has 43,000 * 0.017 = S731.

Greg: After 1 year he has 43,000 * 0.053 = S2279

Difference = 2279 - 731 = S1548.

HELP MUTIPLE CHICE IM BEING TIMED GEOMETRY PICKING SOMEONE FOR Brainliest

ollegr [7]

Answer:

1. SSS

2. Q and S

3. 20

Step-by-step explanation:

1. SSS similarity: If the corresponding sides of two triangles are proportional, then the two triangles are similar.

Triangles NLM and WUV are similar by SSS similarity, because

$\dfrac{NL}{WU}=\dfrac{36}{63}=\dfrac{4}{7}\\ \\\dfrac{LM}{UV}=\dfrac{40}{70}=\dfrac{4}{7}\\ \\\dfrac{NM}{WV}=\dfrac{24}{42}=\dfrac{4}{7}$

2. Completed steps:

a) draw a circle with center at P and radius r

b) draw a circle with center at Q and radius r

c) using compass, measure the distance between two points of intersection of the first circle with angle rays

d) using point of intersection of the second circle with PQ as a center, draw the circle of radius equal to the distance from c) to get point S

Last step: connect points Q and S, line QS will be parallel to line r.

3. If lines MN and UT are parallel, then angles MUT and VMN are congruent; also angles UTN and MNV are congruent.

AA similarity: In two triangles, if two pairs of corresponding angles are congruent, then the triangles are similar .

By AA similarity, triangles VMN and VUT are similar, thus

$\dfrac{VM}{VU}=\dfrac{VN}{VT}\\ \\\dfrac{VM}{VM+8}=\dfrac{49-14}{49}\\ \\49VM=35(VM+8)\\ \\49VM=35VM+280\\ \\49VM-35VM=280\\ \\14VM=280\\ \\VM=20\ units$
