Bogdan [553]

Answer: 7 hr

Step-by-step explanation:

Given

Distance between Emily and Kylie is $140\ \text{miles}$

Speed of Emily $v_e=12\ mph$

Speed of Kylie $v_k=8\ mph$

Distance traveled by Emily $\Rightarrow d_e=12t$

Distance traveled by Kylie $\Rightarrow d_k=8t$

$\Rightarrow 12t+8t=140\\\Rightarrow 20t=140\\\Rightarrow t=7\ hr$

They will meet after 7 hour.

The equation y = 19.43x +609.077 is the equation of the regression line that predicts the number of people attending a county fa

atroni [7]

Answer:

1,114 people

Step-by-step explanation:

The equation $y=19.43x+609.077$ is the equation of the regression line that predicts the number of people attending a county fair, where x is the number of years after 2000.

To find the number of people that are expected to attend the fair in 2026, we determine how many years have passed and substitute into the equation.

From 2000 to 2026,

$2026-2000=26yrs$

have passed.

The expected number who will attend the fair in 2026 is

$y=19.43*26+609.077$

$y=1114.26$

To the nearest whole number 1,114 people will attend in 2026

Any help?? I’ve tried this for a hour and couldn’t figure anything out

Effectus [21]

Answer:

3. PR=51

4. FE=28

Step-by-step explanation:

3. since the two triangles are similar, set up a proportion:

x+8/3x-9=24/28

*cross multiply*:

28(x+8)=24(3x-9)

28x+224=72x-216

44x=440

x=20

to find PR:

PR=3x-9

PR=3(20)-9

PR=51

4. same here:

39/4x+2=42/5x-2

39(5x-2)=42(4x+2)

195x-78=168x+84

27x=162

x=6

to find FE:

FE=5x-2

FE=5(6)-2

FE=28
