Answers

Answer:

18 eggs would cost $3.06 :)

Step-by-step explanation:

Answer:

If 12 eggs cost $2.04, then figure out how much 1 egg costs. You do that by dividing the total by the amount = 0.17. Take that number and multiply by how many eggs and you'll get the total which is $3.06

how do you solve this?

Answers

I’m pretty sure it’s 29°

a line segment has endpoints P(-1,5)and Q(5,2) find the coordinate of that trisect the segment​

Answers

Answer:

(1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

Step-by-step explanation:

Moving from P to Q, we see that x increases by 6  and y increases by 3.

"Trisect" means "divide into three equal subintervals."

We find (1/3) of 6 (which comes out to 2) and (1/3) of 3 (which comes out to 1).  

Thus, the first junction (between 1st and 2nd trisection) is (-1 + 2, 5 + 1), or (1, 6).  The second is (-1 + 2 + 2, 1 + 1 + 1), or (3, 3)

The terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0  is 1.

What is a terminal point?

The terminal point of a circle or circular path is the measure of the angle in degrees or radians over the circle, at the endpoint on the coordinate plane.

The equation for the angle is given as,

[tex]\theta=\dfrac{\pi}{4}\rm radians[/tex]

The terminal point and tan 0 has to be found out.As, the value of pi is 180 degrees. Put this value in the above expression as,

[tex]\dfrac{\pi}{4}=\dfrac{180}{4}=45^o[/tex]

Now, as the rotation of it clockwise from the x-axis in quadrant 1to get the degrees of the angle to the terminal point.

Let this is unit circle with radius 1. Therefore, from the unit circle attached below,

[tex]y=\sin(45)\times1=\dfrac{2}{\sqrt{2}}\\x=\cos(45)\times1=\dfrac{2}{\sqrt{2}}[/tex]

[tex]\tan (45)=1[/tex]

Hence, the terminal point of the 0=pi/4 is (2/√2 and 2/√2) and the value of tan0  is 1.

The volume of a cylinder is 80 cubic centimeters. If the diameter and
height of the cylinder are multiplied by 4/5, what is the volume of the new
cylinder?

Answers

Answer:2 yds and h

Step-by-step explanation:

The volume of the new cylinder will be equal to 40.96 cubic centimeters.

What is the volume of a cylinder?

The amount of space inside a cylinder is its volume. You can find it by dividing the base area by the height.

The formula to calculate the volume of the cylinder is given below:-

V = πr²h

Given that volume of a cylinder is 80 cubic centimeters. The diameter and height of the cylinder is multiplied by 4/5. The new volume will be:-

Vi= πr²h = 80 cubic centimeters.

The new volume will be calculated as:-

Vn= π (4/5r)²(4/5)h

Vn = (64 / 125 )  πr²h

Vn = (64 / 125 ) x Vi

Vn = (64 / 125 ) x 80

Vn = 40.96 cubic centimeters.

Therefore, the volume of the new cylinder will be equal to 40.96 cubic centimeters.

x = 20

Step-by-step explanation:

4x and 5x are same- side interior angles and sum to 180° , then

9x = 180 ( divide both sides by 9 )

x = 20

Answer:

x = 20

Step-by-step explanation:

the two angles are same-side interior angles, thus, the two angles add up to 180°

XOXO

KIT

Answer:

x = 2, x = 4

Step-by-step explanation:

Begin by letting f(x) = 0 , that is

x² - 6x + 8 = 0

Consider the factors of the constant term (+ 8) which sum to give the coefficient of the x- term (- 6)

The factors are - 2 and - 4 , since

- 2 × - 4 = + 8 and - 2 - 4 = - 6 , then

(x - 2)(x - 4) = 0

Equate each factor to zero and solve for x

x - 2 = 0 ⇒ x = 2

x - 4 = 0 ⇒ x = 4
