Margarite is building 3 prototypes of a robot she designed. each robot includes a body and a remote control. she needs 450 inches of wire for each body and 120 inches for each remote control. in addition, she is going to build one master remote to run all three robots at once. the master remote will require 380 inches of wire. write and evaluate a numerical expression to find the total length of wire she will need. write an expression for the amount of wire needed for a robot.

The total length of wire she needed is 2090 inches of wire.

She needs 570 inches of wire for a robot.

Given that,

Margarite is building 3 prototypes of a robot she designed.

She needs 450 inches of wire for each body and 120 inches for each remote control.

The master remote will require 380 inches of wire.

We have to determine,

Write and evaluate a numerical expression to find the total length of wire she will need.

Write an expression for the amount of wire needed for a robot.

According to the question,

Total number robot she designed = 3

Length of wire for each body = 450 inches

Length of wire for each remote control = 120 inches

Length of wire for master remote = 380 inches wire

Then,

Total length = Number of robots(Length of wire for each body + Length of wire for each remote control ) + Length of wire for master remote

Total length = 3(450 + 120) + 380

Total length = 3(570) + 380

Total length = 1710 + 380

Total length = 2090

The total length of wire she needed is 2090 inches of wire.

Therefore,

Each robot includes a body and a remote control

Amount of wire needed for 1 robot = length of wire for body + length of wire for remote control

Amount of wire needed for 1 robot = 450 + 120 = 570

She needs 570 inches of wire for a robot.

The total length of wire she needed is 2090 inches of wire

The expression for the amount of wire needed for a robot is: Amount of wire needed for 1 robot = length of wire for body + length of wire for remote control

Solution:

Number of robots = 3

Given that, Each robot includes a body and a remote control

Length of wire for each body = 450 inches

Length of wire for each remote control = 120 inches

Also, she is going to build one master remote

Length of wire for master remote = 380 inches wire

To find: Total length of wire needed

Total length = Number of robots(Length of wire for each body + Length of wire for each remote control ) + Length of wire for master remote

Thus we get,

Thus the total length of wire she needed is 2090 inches of wire

Write an expression for the amount of wire needed for a robot

Each robot includes a body and a remote control

Amount of wire needed for 1 robot = length of wire for body + length of wire for remote control

Amount of wire needed for 1 robot = 450 + 120 = 570

Thus one robot requires 570 inches of wire

2 & 7

step-by-step explanation:

he climbs 300 ft/hr at a constant rate. the peak is at 1,500 ft.

when going up, he reaches 600 ft in 2 hours. remember, that he is going in a constant rate. divide 600 with 300:

600/300 = 2

assuming that he takes the same route back (meaning that it's a 1500 ft route back, you can solve.

note also that you are solving when he gets back to 600 ft after he reaches the peak.

first, find the amount of hours it takes to get up the peak. divide the total amount (1500), with the ft/her (300) to get the amount of hours (x):

1500/300 = x

x = 5

it takes jamie 5 hours to get up. now, he is returning down, and reaches 600 (his current destination). remember that he climbs at a constant 300 ft/hr. divide 600 with 300:

600/300 = x

x = 2

now add the two numbers together.

x = 5 + 2 = 7

jamie takes 7 hours to go up the mountain and reach his current position when descending.

(total amount/constant rate) = (time).

remember that it is a constant rate, so in total, when he gets back down the mountain, it will take the same amount of time as when he goes up. the total amount for the round trip is: 5 + 5 = 10.
