If the resistance in an electrical cirouit is
held constant, the amount of current
flowing through the circuit is directly
proportional to the amount of voltage
applied to the circuit. When 12v are applied
to a circuit, 240 mA of orrent flow
through the circuit. Find the new current if
the voltage is increased to 14 volts.

Answers

First you must calculate the percentage that was increased. It was increased by 2 and 2 is 1/6 of 12 therefore you must add 1/6 to the potent flow as well .1/6 of 240 is 40 and 240+40=280

Answer:

Explanation:
The Pythagorean theorem states that a^2+b^2=c^2 when c is the longest side (the hypotenuse) and a and b are the other two sides. This theorem can only be applied to right triangles.

First, plug the values into the formula.
a^2+b^2=c^2
8^2+15^2=c^2
64+225=c^2
289=c^2
Take the square root of both sides
c=17

One hundred grams of radium are stored in a container. The amount RR (in grams) of radium present after tt years can be modeled by R=100e−0.00043tR=100e−0.00043t. After how many years will only 5 grams of radium be present? Round your answer to the nearest whole year.

Answers

Answer:

6967 years

Step-by-step explanation:

Given the exponential function :

R=100e−0.00043t

Time = t in years

R = final amount

Number of years in which only 5 grams of radium will be present :

R = 5

Plugging into our formula :

5 = 100 * e^−0.00043t

5 / 100 = e^−0.00043t

0.05 = e^−0.00043t

Take the In of both sides

−2.995732 = - 0.00043t

t = −2.995732 / - 0.00043t

t = 6966.819

t = 6966.819 years

t = about 6967 years

20 times 2 is 40

45 - 40 is 5

A 5 is the difference between the morning and afternoon

Answer:

y = -4

x = 3

Step-by-step explanation:

I will be using the elimination method to solve this:

Begin by times -1 to the bottom equation.

[tex]2x-3y=18[/tex]

[tex]-2x-y=-2[/tex]

Add them together

[tex]0x-4y=16[/tex]

ignore the 0x and divide -4 to both sides

[tex]\frac{-4y}{-4} =\frac{16}{-4}[/tex]

y = -4

Plug y back into one of the two original equations

[tex]2x-3(-4)=18[/tex]

multiply -3 and -4 to get +12

[tex]2x+12=18[/tex]

subtract 12 to both sides

[tex]2x=6[/tex]

divide by 2 to both sides

Write the equation of the line that passes through the points (0,7) and (-4, -9).
Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal
line.

Answers

y=4x+7

First we need to figure out the slope. We can do that using the equation (y2-y1)/(x2-x1). Substitute your numbers in for the xs and ys:

(-9-7)/(-4-0)=

-16/-4=

4

Now that we have the slope, we can figure out the intercept by using the equation y=mx+b and substituting one of the points in for x and y, the slope in for m, and solving for b.

I’m going to use (0,7) as it will be faster:

7=4(0)+b

7=0+b

7=b

The full equation will then be:

y=4x+7

The rectangle is 16 inches by 25 inches. If the scale is 4 in :5 ft what is the length and width of the rectangle in feet.

Answers

Answer:

The length and width of the rectangle are 20 feet and 31.25 feet, respectively.

Step-by-step explanation:

Let the scale be [tex]4\,in\,:\,5\,ft[/tex] and the dimensions of the rectangle being 4 inches and 5 inches, respectively. The scale ([tex]r[/tex]), measured in inches per feet, is equivalent to the following rational number:

[tex]r = \frac{4\,in}{5\,ft}[/tex]

We can convert each length by dividing it by scale factor. That is:

Length

[tex]l' = \frac{16\,in}{\frac{4\,in}{5\,ft} }[/tex]

[tex]l' = 20\,ft[/tex]

Width

[tex]w' = \frac{25\,in}{\frac{4\,in}{5\,ft} }[/tex]

[tex]w' = 31.25\,ft[/tex]

The length and width of the rectangle are 20 feet and 31.25 feet, respectively.
