Jordan will hike the trail shown at a rate of mi/h. Write a linear equation to represent the distance Jordan still has to walk

agasfer [191]

Answer:

<em>y = (-mi/h)x + b</em>

y = total distance left to cover

-mi/h = speed at wich he is covering ground

b = the total distance to cover from start to finish

Step-by-step explanation:

Slope Intercept form without other variables filled is shown like this with <em>mx </em>being the slope and <em>b </em>being the y intercept

<em>y = mx + b</em>

all we need to do is fill in known variables with hours multiplied by <em>x </em>represented as <em>m</em>...

<em>y = (-mi/h)x + b</em>

note the negative symbol, this shows that the higher that miles an hour (mi/h) aka speed is, the more distance he will cover REDUCING the distance to cover faster meaning the line will slope DOWNWARD

<em>b</em> would be the the total distance that he has started with, meaning on the point where the line crosses the y axis, the number it crosses at will represent how much he has started with

7 1/3 + 5 5/6 sum up as a fraction please 100 points

beks73 [17]

Answer:

The answer is 13 1/6

Step-by-step explanation:

The answer is 18 because 7 1/3 turns into 7 2/6 and 7 * 6 is 42 and 42 plus 2 is 44. Next You turn 5 5/6 into a improper fraction which turns into 35/6 and 35 plus 44 is 79/6 and 79/6 simplified is 13 1/6

$20\%\cdot1500\$=0.2\cdot1500\$=300\$$

4.
$\frac{600g}{3kg}=\frac{600g}{3000g}=\frac{600g}{5\cdot600g}=\frac15$
This fraction is $\frac15$

I earn $\$60$

10.
48 minutes = 1 hour - 12 min
21.15 - 1 hour = 20.15
20.15 + 12 min = 20.27

$34.1^oC-27.6^oC=6.5^oC$

12.
$8\frac14 \ h= 8h \ 15min$
$10.30pm+8h = 6.30am\\ 6.30am+15min = \boxed{6.45am}$
I get up at 6.45am

13.
$12\cdot108=1296$

14.
$\overline{x}=\frac{8.2+9.4+3.5+2.9}4=\frac{24}4=6$

15.
$48\cdot26=1248 \ \ \ - \ \ \ total \ amount \ of \ lolipops \ in \ 48 \ bags\\ 1248\cdot20g=24960g = \boxed{24.96kg} \ \ \ - \ \ \ total \ weight \ of \ the \ 48 \ bags\\$

It is not possible to prove one pair of triangles congruent and then use their congruent corresponding parts to prove another pa

borishaifa [10]

Answer:

true

The wording does not quite mean anything,

but what I think was meant to ask is

"if we use some parts of two triangles to prove they are congruent,

can we then use that to prove that

a pair of corresponding parts not used before are congruent?"

The answer is

Yes, of course,

Corresponding Parts of Congruent Triangles are Congruent,

which teachers usually abbreviate as CPCTC.

For example, if we find that

side AB is congruent with side DE,

side BC is congruent with side EF, and

angle ABC is congruent with angle DEF,

we can prove that triangles ABC and DEF are congruent

by Side-Angle-Side (SAS) congruence.

We then, by CPCTC, can conclude that other pairs of corresponding parts are congruent:

side AB is congruent with side DE,

angle BCA is congruent with angle EFD, and

angle CAB is congruent with angle FDE.

It was possible (by CPCTC) to prove those last 3 congruence statements,

after proving the triangles congruent.

The expected answer is FALSE.
