You would subtract 6 from the 6 on the right and then subtract 6 from the -4 and get -10 and that is the answer m=-10

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

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

a box contains 1 3/4 pounds of pancake mix. Jada used 7/8 pound for a recipe. What fraction of the pancake mix in the box did sh

ololo11 [35]

Answer:

Jada used 1/2 of the pancake mix in the box

Step-by-step explanation:

we know that

$1\frac{3}{4}\ pounds$ -----> represent the 100% of the box

by proportion

Find what fraction represent $\frac{7}{8}\ pounds$

First convert mixed number to an improper fraction

$1\frac{3}{4}\ pounds=\frac{1*3+4}{4}=\frac{7}{4}\ pounds$

$\frac{100}{(7/4)}=\frac{x}{(7/8)}\\ \\x= 100*(7/8)/(7/4)\\ \\x=50\%$

Convert the percentage into fraction

$50\%=50/100=1/2$

In the year 2005, a total of 750 fish were introduced into a man made lake. The fish population was expected to grow at a rate o

Butoxors [25]

Answer:

In 2050 fish population is 27000

Step-by-step explanation:

Exponential change can be modeled by,

$F=F(0)+x^{n}$

Where $F(0)$ is the initial value of 750, $x$ is the rate of change. It is greater then 1 when there is growth and less then 1 when there is decay. and $n$ is the number of time periods.
