Answer:

First one: yes

Second one: yes

Third one: no

Step-by-step explanation:

To find the midpoint of a line segment, you take the x and y coordinates of the 2 points, add each of them up, and divide each of them by 2.

First one: x = (1+3)/2 = 2, y = (2+4)/2 = 3, so it's correct.

Second one: x = (-1+3)/2 = 1, y = (1+-1)/2 = 0, so it's correct.

Third one: x = (-3+-1)/2 = -2, y = (0+5)/2 ≠ 2, so it's not correct.

I really hope this helped.

When the prefix milli is used, it means multiply the number by ? ?

valina [46]

1 meter = 1000 millimeters

so, 5 meters = 5*1000 = 5000 millimeters

and 6000 millimeters = 6000 / 1000 = 6 meters

Javier has four cylindrical models. The heights, radii, and diagonals of the vertical cross-sections of the models are shown in

Ronch [10]

The model in which the lateral surface meets the base at right angle is : Model 1.

<h3>What is a lateral surface?</h3>

The lateral surface of an object is all surfaces of that object excluding its base and top.

Analysis:

To know the exact model, we check for the models in which their dimensions form a Pythagorean triplet otherwise a right-angled triangle.

For Pythagorean triplet, the square of the diagonal must be equal to the sum of squares of the other two sides.

Model 1

Diagonal = 50cm, radius = 14cm, lateral height = 48cm

$(50)^{2}$ = $(14)^{2}$ + $(48)^{2}$

2500 = 196 + 2304

2500 = 2500. Forms Pythagorean triplet

Model 2

Diagonal= 37cm, radius = 6cm lateral height = 35cm

$(37)^{2}$ = $(35)^{2}$ + $(6)^{2}$

1369 = 1225 +36

1369 $\neq$ 1261

Model 3

Diagonal = 60cm, radius = 20cm lateral height = 40cm

$(60)^{2}$ = $(20)^{2}$ + $(40)^{2}$

3600 = 400 + 1600

3600 $\neq$ 2000

Model 4

Diagonal = 30cm, radius = 24cm, lateral height = 9cm

$(30)^{2}$ = $(24)^{2}$ + $(9)^{2}$

900 = 576 + 81

900 $\neq$ 657

Therefore the lateral surface model 1 meets the base at right angle

In conclusion, the lateral surface of model 1 meets the base at right angles as the dimensions form a right-angled triangle.

Cornelius is building a solar system model. He plans on making a circular ring around one of the planets out of wire. He wants t

astra-53 [7]

Answer:

$C = 2\pi r$

$C = \pi d$

Step-by-step explanation:

Given

A circular ring

Required

The length

Let

$r \to$ the radius of the ring

The length is calculated by calculating the circumference of the ring.

This is calculated using:

$C = 2\pi r$

$C = \pi d$

Where

$d \to$ diameter

and $d = 2r$

Find the surface area of the prism.

DanielleElmas [232]

Answer:

2 x 5 = 10, 10 x 2 = 20

4 x 2 = 8, 8 x 2 = 16

5 x 4 = 20, 20 x 2 = 40

40 + 20 + 16 = 76 yd^2 is your answer.
