During a road trip Tony , Tony drove one third the distance that Lana drove. Mark drives 15 more than Lana drove .The total dist

ale4655 [162]

Answer:

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles

Step-by-step explanation:

Given as :

The total distance cover by Lana , Tony , Mark = 484 miles

Let The distance drove by Lana = L miles

The distance drove by Tony = T

The distance cover by Mark = M

So , L + T + M = 484 miles

Now, The distance of Tony = $\frac{1}{3}$ of Lana distance

Or, T = $\frac{1}{3}$ × L

And The distance of Mark = 15 + The distance of Lana

Or, M = 15 + L

Now.

L + $\frac{1}{3}$ × L + 15 + L = 484

Or, 2 L + $\frac{L}{3}$ = 484 - 15

Or, 2 L + $\frac{L}{3}$ = 469

Or, $\frac{7 L}{3}$ = 469

Or, 7 L = 469 × 3

∴ L = $\frac{1407}{7}$

I.e L = 201

The distance drive by Lana = 201 miles

The distance drive by Mark = 15 + L =15 + 201 = 216 miles

The distance drive by Tony = $\frac{1}{3}$ × 201 = 67 miles

Hence The distance drive by each person is

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles Answer

Construct the perpendicular bisector for the segment in the following figure. What process did you use? Explain.

babymother [125]

Answer:

Perpendicular bisector for the given segment AB is shown below.

Step-by-step explanation:

Construction steps for the perpendicular bisector for the given segment AB are:

1. Open your compass more than half of the distance between end points of the given segment, i.e., A and B.

2. Place the compass on point A and mark two arc on each side of line segment AB.

3. Place the compass on point B and mark two arc on each side of line segment AB, which intersect the previous arcs.

4. Arcs meet at two points. Mark them C and D.

5. Draw the line between C and D.

The perpendicular bisector for the given segment AB is shown below.

A 440.0-volt electric heater draws 10.0 amperes of current. according to Ohms law,what is the resistenace of the heater

Zanzabum

Answer:

The resistance of the heater is 44 ohms.

Step-by-step explanation:

Given that,

Voltage of electric heater, V = 440 volts

Current drawn by the heater, I = 10 A

We need to find the resistance of the heater. It is a case of Ohm's law. Its mathematical form is given by :

$V=IR$

R is resistance of the heater

$R=\dfrac{V}{I}\\\\R=\dfrac{440\ V}{10\ A}\\\\R=44\ \Omega$

So, the resistance of the heater is 44 ohms. Hence, this is the required solution.

Stuck in this question from 4 days!!<br> Help please.

LenKa [72]

Answer:

C. 55s

Step-by-step explanation:

I'll refer to Wyndham as W and Michael as M.

Also, we will be assuming constant speed for both runners.

So, first of all, W ran with a speed of 8m/s;

400m/50s = 8 m/s

M ran with speed 9.2635.... m/s;

400m/43.18s = 9.26.... m/s

The difference is 1.26.... m/s, meaning every second, the distance between M and W would increase by 1.26.....m, starting from 0 at the start line;

9.26... - 8 = 1.26....

So, to find the desired distance, we simply multiply 1.26... by 43.18;

1.26... × 43.18 = 54.560....

(Rounded up to 55s)

Add the two expression<br><br> -2.4n-3and-7.8n+2

torisob [31]

You have to combine like terms so you have to add -2.4n and -7.8n which will give you -10.2n. Then you need to combine the -3 and 2 which will give you -1. So you will end up with
-10.2n - 1

Hope that helps!
