Answer:

6.50

Step-by-step explanation:

C = 2πr

40.8 = 2(3.14)r

40.8 = 6.28r

r = 6.50

Answer:

it would be 6.49

Step-by-step explanation:

Circumference=2πr but in this case it is 40.8=2(3.14)r

So you would multiply 2 times 3.14 so now you are at 40.8=6.28r

Then you divide 40.8 by 6.28 to isolate the r and it would equal to approximately 6.49 for r or the radius.

Step-by-step explanation:

By binomial theorem,

T(r+1) = nCr * a^(r+1) * b^r

Term 4 = 7C3 * (2x)^4 * (-5y)^3 = 35 * (16x^4) * (-125y^3) = -70000x^4y^3.

The solution is,  : The figure shows a line tangent to the circle is, 4th figure.

As we know that, a tangent can be mentioned as a line segment to a circle which intersect the circle at exactly one point and that point is a tangency point.

here, we have,

the given figures,

we have to find the line  that is tangent to the circle.

we know that,

a tangent is a line segment to a circle which intersect the circle at exactly one point and that point is a tangency point.

And the radius from the center of the circle to the point of tangent is always perpendicular to the tangent line.

now, from this figures we get,

From this we conclude that, 4th figure is a right angled triangle that means the radius from the center of the circle to the point of tangent is always perpendicular to the tangent line.

Hence, The figure shows a line tangent to the circle is, 4th figure.

16/8 + 5 x 2

to solve it we must solve the multiplication or division first

lets solve division first

16/8=2

=2 + 5 x 2

then we solve the multiplication

5 x 2=10

=2 + 10

now its simpler so

Step-by-step explanation:

Giving the following information:

She must pay $200 to rent a booth at the craft fair. The materials for each pendant cost $7.80, and she plans to sell each pendant for $13.50.

We weren't provided with questions to answer. But, I will assume that we need to determine the number of units to be sold to break-even.

To calculate the break-even point in units and dollars, we need to use the following formulas:

Break-even point in units= fixed costs/ contribution margin per unit

Break-even point in units= 200 / (13.5 - 7.8)

Break-even point in units= 35 units

Break-even point (dollars)= fixed costs/ contribution margin ratio

Break-even point (dollars)= 200 / (5.7/13.5)

Break-even point (dollars)= $473.68

If you want to reach a certain profit:

Break-even point in units= (fixed costs + desired profit) / contribution margin per unit

Break-even point (dollars)= (fixed costs + desired profit) / contribution margin ratio

Answer:

106 and 74 degrees.

Step-by-step explanation:

Since 90 + 90 = 180, if you just add 16 to 90 you will get 106. Then you can subtract 106 from 180, which gives you 74 degrees.

Step-by-step explanation:

If the fish are closser to the suface it will be closer to 0 on the number line.

A fish finder is an instrument on a boat that indicates that fish are located in a radius of -20 to 0.

Given that,
A fish finder is an instrument on a boat that indicates where fish are located. The range of the fishfinder is to be specified.

Range, it is the set of the values that come out to an outcome for certain mathematical operations.

A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.

Here,
The range usual range of the fishfinder is standardly 0 to -20 on the number line of the instrument, where the negative sign indicates the depth.
