Find the surface area

Answer:

18.84 inches

Step-by-step explanation:

The circumference of a circle is found by

C = 2 * pi *r  where r is the radius

C = 2 * pi * 3

C = 6 pi

Approximating pi by 3.14

C =6*3.14

C =18.84 inches

Answer:

18.84 in

Step-by-step explanation:

[tex]Solution,\\\\Radius(r)=3in\\\\Now,\\\\Circumference=2\pi r\\\\Circumference=2*\pi *3in\\\\Circumference=18.84in[/tex]

Using the z-distribution, as we are working with a proportion, considering that the estimate is of 90%, the 95% lower​ limit is of 0.8785.

A confidence interval of proportions is given by:

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which:

In this problem, we have that:

Hence, the lower bound of the interval will be given by:

[tex]\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.9 - 1.96\sqrt{\frac{0.9(0.1)}{750}} = 0.8785[/tex]

Answer:

one solution:1

infinite no. of solutions: 2

no solution:3

Step-by-step explanation:

one solution because it intersects in one point

infinite no. of solutions because we have only one line so we have infinitely many solutions.

no solution because 2 parallel will never intersect

The least number of mice that he has to take out of his hat would be 23.

We have the following details to solve this problem

x = 14

t = 8

u = 6

n1 = x + t + 1

= 14 + 8 + 1 = 23

​

n2 = t + u + 1

= 8 + 6 + 1 = 15

​

n3 = x + u + 1

= =14+6+1=21

From here the

max n (n1, n2, n3) = 23, 15, 21

Hence the least number that has to be taken out would be 23.

Length of longer side of the rectangle in which a quarter circle is drawn onto the shorter side is 5.12 cm

The area of a two dimensional shape is the space enclosed by the boundary of the shape. The area of a rectangle is the product of its length and breadth, the area of a circle is π×(radius)².

Given that, the shorter side of a rectangle is 4cm.

Let the length of the longer side of the rectangle is x.

Then, the area of rectangle is 4x

Also, the sum of area of rectangle and a quarter circle is 33.4cm²

And the radius of quarter circle = shorter side of rectangle

Therefore, area of quarter circle = (1/4)×π(4)²

According to question,

    4x + (1/4)π(4)² = 33.4

     4x + 4π = 33.4

     4x = 33.4 - 4×3.14

     4x=20.84

       x=5.21

Hence, the longer side of rectangle is 5.21 cm when the shorter side is 4cm and a quarter circle is drawn onto the shorter side of the rectangle.

Answer:

[tex]\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}[/tex]

Step-by-step explanation:

Start by making a common denominator. That way we can just compare the numerators of the fractions and easily order then from least to greatest. Start by finding the LCM(least-common-multiple) of the denominators.

The LCM of 3, 4, and 5, is 60.

So let's make each of the fractions have a denominator of 60.

Start with [tex]\frac{2}{5}[/tex],

[tex]\frac{2}{5} =\frac{x}{60}[/tex], no we have to solve for x, and since we multiply by 12 to get to 60 from 5, we multiply 2 by 12 as well.

So, [tex]x=24[/tex].

Now do the same for each fraction.

[tex]\frac{1}{3} =\frac{x}{60}[/tex], we multiply by 20, so [tex]x=20[/tex]

[tex]\frac{4}{5} =\frac{x}{60}[/tex], we multiply by 12, so [tex]x=48[/tex]

[tex]\frac{3}{4}=\frac{x}{60}[/tex], we multiply by 15, so [tex]x=45[/tex]

So now are new fractions are [tex]\frac{24}{60} , \frac{20}{60} ,\frac{48}{60} , \frac{45}{60}[/tex]

Now just order these like normal since they have a common denominator.

[tex]\frac{20}{60} ,\frac{24}{60} , \frac{45}{60} , \frac{48}{60}[/tex]

Now revert them and make them there original values

[tex]\frac{1}{3}, \frac{2}{5} , \frac{3}{4} , \frac{4}{5}[/tex]
