A person is connecting heat trace cable on pipe at the jobsite. The cable he or she is using is rated 2.5 watts/foot. How many f
maksim [4K]

The length of the cable will be 6 feet which can be installed  120-volt/15-amp circuit.

<h3>What is an ampere circuit?</h3>

Ampere's circuital law states that “the line integral of the magnetic field surrounding closed-loop equals to the number of times the algebraic sum of currents passing through the loop.”

Here we have a cable rating of 120-volt/15-amp so if the 1-ampere circuit means 1 watt per foot cable will be used for the 1-ampere circuit.

A Total of the 15-ampere circuit means 15 watts needed so we are using 2.5 watts per foot.

\rm Length \ of\  Cable =\dfrac{15}{2.5}=6 \ \ foot

Hence the length of the cable will be 6 feet which can be installed  120-volt/15-amp circuit.

Molly has cups of sugar. She used cup of sugar. She wants to model a subtraction problem on a number line to find how much sugar
vovangra [49]
I am going off the assumption that by "She used a cup of sugar" you mean that she used 1 cup of sugar. Since the model shows that her first step starts with 1.5, that means that she loses 1 cup, and moves 1 unit to the left. She is left with 0.5 cups of sugar.
B. She only moves 1 unit to the left.

Find the area of a triangle with a base (b) of 7 feet and a height (h) of 12 feet.
siniylev [52]

Answer:


Step-by-step explanation:

Area = 1/2 × base × height

Base(b) = 7 feet

Height(h) = 12 feet

Area = 1/2 × 7 × 12 = 7 × 6 = 42 feet²

Find the equation of the linear function represented by the table below in slope-intercept form.
Vitek1552 [10]

Answer:

y = 10x - 8

Step-by-step explanation:

The slope is "m", or how much the y-value changes on a line when the x-value changes by one.

The y-intercept is the y value of the line when it is intersecting the y-axis, or when the x-value is 0.

To find the slope, take 2 points from the graph and plug into the slope formula:

\frac{y_2-y_1}{x_2-x\\_1}

I'll use (0, -8) and (1,2).

Plug into the formula.

\frac{2--8}{1-0}

\frac{10}{1}

10

Slope = 10

To find the y-intercept, look at the table. What is the y-value when the x-value is equal to 0?

-8

y-intercept: -8

Slope-Intercept form:

y = mx + b

m: slope

b: y-intercept

y, x: leave as variables

y = 10x - 8

Please help with homework!!!!‼️‼️‼️‼️‼️‼️
Marysya12 [62]

Answer:

  1. 3.04 m
  2. 18

Step-by-step explanation:

The midsegment of a triangle is half the length of the side it is parallel to.

1. For a distance of 6.08 m between wall plates, the colar tie will be half that, or 3.04 m.

2. The perimeter of ΔXYZ is ...

... 10 + 12 + 14 = 36

The sides of ΔABC are half the length of the sides of ΔXYZ, so the perimeter of ΔABC is half the perimeter of ΔXYZ.

... perimeter of ΔABC = 36/2 = 18
