A human's eyeball is shaped like a sphere with a diameter of 2.5 cm. A
dog's eyeball is shaped like a sphere with a diameter of 1.75 cm. About
how many times greater is the volume of a human's eyeball than the
volume of a dog's eyeball?

Answers

Answer:

I think it is 1.5

Step-by-step explanation:

I'm not that sure sorry :(

Volume of human eyeball is 3 times more than volume of dog's eye .

Given,

Human eyeball diameter = 2.5 cm

Dog eyeball diameter = 1.75 cm

Now,

Firstly calculate the volume of humans eye,

Volume of sphere = 4/3 πr³

r = radius of eyeball

r = d/2

r = 2.5/2

r = 1.25 cm

Volume = 2.60π cm³

Now calculate the volume of dogs eye,

V = 4/3 πr³

r = d/2

r = 1.75/2

r = 0.875 cm

V = 0.893π

Thus from the calculation volume of human eye is more by approximately 3 times .

A circle has a circumference of 12. What is the area of the circle and how do you find it?

Answers

Answer:36cm

Step-by-step explanation:The area of a circle is pi times the radius squared (A = π r²

a) Diameter is 12cm

; (b) radius is 6cm

; and (c) area is 36πcm2.

Explanation:If r is the radius of a circle, then its circumference is 2πr

and area is πr2.

As circumference is given to be 12π, we have 2πr=12π

or r=12π2π=6cm.

As such radius is 6cm

and diameter being double of radius, diameter is 2×6=12cm.

and area is π×62=36 cm2

Blake, Chang, and Grace together sold 71 tickets for the school banquet. Blake sold 27 tickets and Chang sold 28 tickets. How many tickets did Grace sell? (5 points) 16 43 44 55

Answers

Answer:

Step-by-step explanation:

because to get what you need add 27 and 28 and you get 55 then subtract 71 by 55 to get 16

71-(27+28)

Answer:

Grace sold 16 tickets.

Step-by-step explanation:

We have a total of 71 tickets sold between 3 people. Blake sold 27 tickets and Chang sold 28 tickets. Adding those sold by Blake and those sold by Chang, gives us: 27 + 28 = 55, if that amount is subtracted from the total sales that are 71 tickets, the result would be: 71 - 55 = 16, which would be the tickets sold by Grace.

Answer:

y=3/4x +7

Step-by-step explanation:

The equation for slope-intercept is y=mx+b, where m is the slope and b is the intercept.

To find b, we can plug in the x,y, and given slope.

[tex]4 = \frac{3}{4} ( - 4) + b \\ 4 = - 3 + b \\ b = 7[/tex]

so now we can write b and m in the original equation.

which gives us, y =3/4x +7

find the solution in 0< x < 2π
cos 2x = 2sinx

Answers

Answer:

[tex]\displaystyle x=\left\{\arcsin\left(\frac{-1+\sqrt{3}}{2}\right), \pi-\arcsin\left(\frac{-1+\sqrt{3}}{2}\right)\right\}[/tex]

Or their approximations:

[tex]x\approx \left\{0.375, 2.767\right\}[/tex]

Step-by-step explanation:

We are given:

[tex]\cos(2x)=2\sin(x)[/tex]

And we want to find the solution in [0, 2π).

Recall the double-angle identities for cosine:

[tex]\begin{aligned} \cos(2x)&=\cos^2(x)-\sin^2(x) \\&=2\cos^2(x)-1\\&=1-2\sin^2(x)\end{aligned}[/tex]

We will use the third version. Hence:

[tex]1-2\sin^2(x)=2\sin(x)[/tex]

Move all terms to one side:

[tex]-2\sin^2(x)-2\sin(x)+1=0[/tex]

This is now in quadratic form. For simplicity, let u = sin(x):

[tex]-2u^2-2u+1=0[/tex]

Solve for u. Simplify:

[tex]2u^2+2u-1=0[/tex]

By the quadratic formula:

[tex]\displaystyle u=\frac{-(2)\pm\sqrt{(2)^2-4(2)(-1)}}{2(2)}}[/tex]

Evaluate:

[tex]\displaystyle u=\frac{-1+\sqrt{3}}{2}\approx 0.366\text{ and } u=\frac{-1-\sqrt{3}}{2}\approx-1.366[/tex]

Note that the second solution is > -1. Hence, we will disregard it. (The range of sine is only -1 ≤ y ≤ 1.)

Back-substitute:

[tex]\displaystyle \sin(x)=\frac{-1+\sqrt{3}}{2}[/tex]

Since it is approximately 0.366, it will occur twice (once in QI and again in QII. This is because sine is positive only in those two quadrants). Using a calculator:

[tex]\displaystyle x_1=\arcsin\left(\frac{-1+\sqrt{3}}{2}\right)\approx0.375[/tex]

Using reference angles, the other solution is:

[tex]\displaystyle x_2=\pi -x_1=\pi -\arcsin\left(\frac{-1+\sqrt{3}}{2}\right) \approx2.767[/tex]

Complete the system of equations that can be used to find the number of each type sold. The system is braceleftze 76x + y = x + y =

Answers

Answer:

The system of equations that can be used to find the number of each type sold is given as:

x + y = 17 ...... Equation 1

76x + 141y = 1460....... Equation 2

Step-by-step explanation:

Let

x represent the number of polyester-fill bags sold

y represent the number of down-fill bags sold.

In one week the store sold 17 sleeping bags

x + y = 17 ...... Equation 1

x = 17 - y

At Raging River Sports, polyester-fill sleeping bags sell for $76. Down-fill sleeping bags sell for $141. In one week the store sold 17 sleeping bags for $1,460.

Hence:

$76 × x + $141 × y = $1460

76x + 141y = 1460....... Equation 2

Therefore, the system of equations that can be used to find the number of each type sold is given as:

x + y = 17 ...... Equation 1

76x + 141y = 1460....... Equation 2
