Answer:

  B.  18 cm²

Step-by-step explanation:

The area of a trapezoid can be found using the formula ...

  A = 1/2(b1 +b2)h

For the given dimensions, the area is ...

  A = 1/2(7 cm +5 cm)(3 cm) = 1/2(12)(3) cm² = 18 cm²

The circumference of the circle shows that the number of stones needed will be 13.

To calculate the value of the circumference of the circle, we use the formula C = 2πr, where r is the radius of the circle, and π  is a constant l.It should be noted that the circumference of a circle is calculated by using the formula:

[tex]= 2\pi r\\= 2 * 3.142 * (4/2)\\= 12.568\\= 13[/tex]

Answer:

[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]

Step-by-step explanation:

Let the number of cups of onions Katrina still needs to chop = x

She has already chopped the onions = [tex]1\frac{1}{3}[/tex] cups ≈ [tex]\frac{4}{3}[/tex] cups

So total amount of chopped onions = [tex](x+\frac{4}{3})[/tex] cups

Since, onion soup recipe calls for the chopped onions = [tex]3\frac{2}{3}[/tex] cups ≈ [tex]\frac{11}{3}[/tex] cups

Therefore, equation which shows the number of cups of onions to be chopped more will be,

[tex]x+1\frac{1}{3}=3\frac{2}{3}[/tex]

We further solve this equation for the value of x,

x = [tex]\frac{11}{3}-\frac{4}{3}[/tex]

x = [tex]\frac{(11-4)}{3}[/tex]

  = [tex]\frac{7}{3}[/tex] cups

  ≈ [tex]2\frac{1}{3}[/tex] cups

0.0000175631 or [tex]\frac{175631}{10000000000}[/tex]

Step-by-step explanation:

[tex]\frac{(1.6)(10^{-7})}{(9.11)(10^{-3})}[/tex]

Solve Numerator

[tex](1.6)(10^{-7})=(1.6)(\frac{1}{10000000})=\frac{16}{100000000} =0.00000016[/tex]

Solve Denominator

[tex](9.11)(10^{-3})=(9.11)(\frac{1}{1000} )=\frac{911}{100000} =0.00911[/tex]

Divide

[tex]0.00000016/0.00911[/tex]

0.0000175631 or [tex]\frac{175631}{10000000000}[/tex]

Step-by-step explanation:

A black bar with 7 copper colored coils around it is the strongest.

Electromagnets are defined as magnet which works through electricity.

We know permanent magnets show magnetic properties every time. We cannot alter it. But electromagnets only acts as a magnet when current passes through it. Otherwise, it is just a coiled wire.

Strength of electromagnet depends on basically two things:

First, the amount of current flowing through the wire and

Second, the number of turns of wire around the coil.

Here there are four electromagnets which are black bar with 5, 2, 7 and 4 copper colored coils around it.

Number of coils is maximum for the black bar with 7 copper colored coils around it, which results in the strongest electromagnet.

Hence, a black bar having 7 copper colored coils around it is the strongest.

Ok. First, let's find the slope using the slope formula.

[tex]m = \frac{y2-y1}{x2-x1} =\frac{9-5}{2-2} = 4/0[/tex]

4/0 is undefined.

When the slope is undefined, that means that it's a straight line going down from the x.

So the equation is just x = 2

Answer:

C: y + 3 = 1/4(x + 4)

Step-by-step explanation:

Perpendicular to a given line means opposite inverse of the slope...

Equation of line is: y = -4x - 3

slope in above equation is -4, perpendicular would be 1/4

Perpendicular equation of a line through P(-4, -3):

y = mx + b

-3 = 1/4(-4) + b

-3 = -1 + b

b = -2

Use perpendicular slope and the b from above to form the perpendicular equation of line:

y = 1/4x - 2

Check:

(-3) = 1/4(-4) - 2

-3 = -1 - 2

-3 = -3

Answer:

y= 3x - 5

Step-by-step explanation:

coordinates given: (4,7) & (1, -2)

to find m (slope) = rise/run = (y2-y1) /(x2-x1)

= ( -2-7) / (1 - 4)

= -9/-3

= 3

therefore, y=3x + b

to find b:

taken coordinate: (4,7)

y=3x + b

7=3 (4) + b

7= 12 + b

7-12 = b

-5 = b

(*the value of b will be same even if we take the other coordinate)

therefore, y = 3x -5
