Answer:

I got 678.58401 but i think it is C. 648n cubic units

Step-by-step explanation:

Answer:

[tex]x^2 + (y-60)^2 = 30,625[/tex]

Step-by-step explanation:

There are 42 carts, so there is 42 spaces in between them; if one of those spaces are 25pi/3 feet long, then 42 of them would be 25*42*pi/3 = 350pi (Perfect! no fractions)

350pi is the circumference. Now if we plug that into the circumference equation we get:

C = 2pi*r

350pi = 2pi*r

Divide both sides by pi to get rid of it

350 = 2r

Divide both sides by 2

r = 175 feet

So the new equation to graph it is:

x^2+y^2 = 175^2 = 30,625

We also know that the center of the Ferris wheel has to be at least 60 feet from the ground. Since the radius is more than that, a good bit of the Ferris wheel has to be underground OR we can make it higher (keyword: at least) if we want it to be above ground. I'll do the equation for underground since it more closely represents the question.

subtracting a number from y, shifts the graph up that much so:

[tex]x^2 + (y-60)^2 = 30,625[/tex]

I can't really draw it electronically but I can graph it:

Answer:

"76°" is the appropriate solution.

Step-by-step explanation:

Please find attachment of the diagram according to the given query.

The given values are:

In ΔDEF,

f = 610 inches

e = 590

∠E = 70°

∠F = ?

By using the law of sines, we get

⇒  [tex]\frac{Sin E}{e} =\frac{Sin F}{f}[/tex]

On substituting the values, we get

⇒  [tex]\frac{Sin70^{\circ}}{590} =\frac{SinF}{610}[/tex]

On applying cross multiplication, we get

⇒   [tex]SinF=\frac{610\times Sin 70^{\circ}}{590}[/tex]

On substituting the values, we get

⇒            [tex]=\frac{61\times 0.95969262}{59}[/tex]

⇒            [tex]=\frac{57.3212499}{59}[/tex]

⇒            [tex]=0.971546608[/tex]

now,

⇒  [tex]F=Sin^{-1}(0.971546608)[/tex]

⇒      [tex]=76^{\circ}[/tex]

Answer:

lateral surface area of cone =

[tex]\pi rl[/tex]

where, l = slant height, and r = radius

then

[tex]l.a = \pi \times 8 \times 17[/tex]

[tex]l.a = 136\pi[/tex]

The lateral area of this cone will be 136 π. Lateral area is found as the product of pi ,radius and slant height.

It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.

lateral area of this cone is found as;

L=πrl

L=π×8×17

L=136π

Hence,the lateral area of this cone will be 136 π.

Answer:

the length of side X is 37

Answer:

x = 26.4°

Step-by-step explanation:

Defence angle = x

Side length Opposite to reference angle = 4

Hypotenuse length = 9

Apply trigonometric ratio, SOH. Thus:

Sin x = Opp/Hyp

Sin x = 4/9

[tex] x = sin^{-1}(\frac{4}{9} [/tex]

x = 26.3878° = 26.4° (nearest tenth)

Answer:

d.) 1/12

Step-by-step explanation:

As it is equal to 0.083 and it is nearest to zero

Answer:

d. 1/12

Step-by-step explanation:

Since all of the fractions are positive and you want the one closest to 0, you need to find the smallest fraction. With fractions, especially when all of the numerators are 1, the larger the denominator becomes, the smaller the fraction. 12 is the largest denominator; therefore, 1/12 must be the smallest fraction. Which makes 1/12 the closest to 0.

Answer:

Answer:

V = 260.2 m^3

Step-by-step explanation:

The area of the circular base is (pi)(r)^2, where r is the radius and half the diameter.

In this case the volume of the cone is V = (1/3)(pi)(5 m)^2*(10 m) = 260.2 m^3

The value of log 8 is 0.9030

Step-by-step explanation:

To find:

Value of log 8

Solution:

Let we take,

x=log8

x=log (2)^3

x=3log2

x=3*0.3010

x=0.9030

Hence, the value of log 8 is 0.90.

Answer: sum: 51 + -31 = 20

Step-by-step explanation: The sum of two numbers is 20 and their difference is 92. What are the two numbers? Let's start by calling the two numbers we are looking for x and y.

The sum of x and y is 20. In other words, x plus y equals 20 and can be written as equation A:

x + y = 20

The difference between x and y is 92. In other words, x minus y equals 92 and can be written as equation B:

x - y = 92

Now solve equation B for x to get the revised equation B:

x - y = 92

x = 92 + y

Then substitute x in equation A from the revised equation B and then solve for y:

x + y = 20

92 + y + y = 20

92 + 2y = 20

2y = -72

y = -36

Now we know y is -36. Which means that we can substitute y for -36 in equation A and solve for x:

x + y = 20

x + -36 = 20

X = 56

Summary: The sum of two numbers is 20 and their difference is 92. What are the two numbers? Answer: 56 and -36 as proven here:

Answer:

[tex]y=-\frac{1}{5} x-1[/tex]

Step-by-step explanation:

Hi! Welcome to brainly!

So slope intercept form - y = mx + b

where m = slope and b = y intercept

First lets find the y intercept

The y intercept is at (0,-1)

B would equal the y value of the y intercept so b = -1

now lets find the slope

To do so we can pick 2 points on the line and use the slope formula

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

the points can vary but i chose the points (5,-2) and (10,-3)

having found the points we plug them into the formula

[tex]m = \frac{-3-(-2)}{10-5} \\-3-(-2)=-1\\10-5=5\\m=-\frac{1}{5}[/tex]

now that we have found all of the information we plug the values into the equation and get that the answer is

[tex]y=-\frac{1}{5} x-1[/tex]

Answer:

This triangle is an isosceles acute

Step-by-step explanation:

First lets define each classification

scalene - no equal sides

isosceles - two equal sides

equilateral - all equal sides

acute - all angles have a measure of less than 90 degrees

right - has a right angle (90 degree angle)

obtuse - has an angle that has a measure of more than 90 degrees

Now lets classify

The triangle has two equal sides (indicated by the little line on the top and bottom side) therefore it is an isosceles triangle

We know its an acute triangle because the one angle given is not a right angle nor a obtuse angle meaning that the other two angles are going to have  a measure of less than 90 degrees

So we can conclude that this is an isosceles acute triangle

I hope this helps you
