1.A 2000 W toaster operates on a household circuit of 200 V. What is the resistance of the wire the make up the heating element

MakcuM [25]

P - power measured in watts
E - voltage measured in volts
I - current measured in amperes
R - resistance measured in ohms

$E=IR
\\P=IE$

1. P = 2000 W, E = 200 V, R = ?

$P=IE
\\2000=I200 
\\I=10
\\E=IR
\\200=10R
\\R=20$

2. P = 0.35 W, E = 150 V, R = ?

$P=IE
\\0.35=I150
\\I= \frac{0.35}{150}
\\ E=IR
\\150=\frac{0.35}{150}R
\\R= \frac{150^2}{0.35}
\\R= 64285.71$

For the data in the table tell whether y varies directly with X if it does write an equation for the direct variation

frozen [14]

a) Option B Direct variation, y=1.8x is correct option.

b) Option A Not a direct variation is correct option.

Step-by-step explanation:

a) for the data in the table tell whether y varies directly with X if it does write an equation for the direct variation

The direct variation is represented by:

$y=kx \,\,or\\\frac{y}{x}=k$

We need to find k.

Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly

$\frac{5.4}{3}=1.8\\\frac{12.6}{7}=1.8\\\frac{21.6}{12}=1.8$

Since value of k is constant i.e 1.8 so, y varies directly with x.

Option B Direct variation, y=1.8x is correct option.

b) For the data in the table tell whether Y varies directly with x if it does write an equation for the direct variation.

The direct variation is represented by:

$y=kx \,\,or\\\frac{y}{x}=k$

We need to find k.

Given the values of x and y in table we will find k. if value of k is constant, so x and y varies directly

$\frac{1}{-2}=-\frac{1}{2}\\\frac{6}{3}=2\\\frac{11}{8}=1.3$

Since value of k is not constant so, y doesn't varies directly with x.

Option A Not a direct variation is correct option.

In Chicago, a person must pay 9.5% of the price of a couch in

ser-zykov [4K]

Answer: $820

Step-by-step explanation:

Use a proportion

9.5/100 = 77.90/x

Multiply 77.90 times 100 and divide by 9.5, the answer is $820

Lincoln is measuring the angles of quadrilateral WXYZ to determine whether it is congruent to the quadrilateral below. Quadrilat

Artist 52 [7]

Answer:

If quadrilateral WXYZ is congruent to quadrilateral RSTQ, then its corresponding elements are also congruent.

That is,

$\angle R = 140\°= \angle W\\\angle S= 94 \° = \angle X\\\angle T= 79\° = \angle Y\\\angle Q = 47 \° = \angle Z$

Also,

$WX=RS\\XY=ST\\YZ=TQ\\WZ=RQ$

Therefore, the right answer is None of the Above.
