the perimeter of a semicircle is 5.14 millimeters what is the semicircle diameter

Answers

Answer 1

Answer:

2 mm

Step-by-step explanation:

let the radius of the semi-circle be r

Then,

length of curved portion = 1/2 x circumference = (1/2) (2)(π)r = πr

length of straight portion = diameter of circle = 2r

Hence, we can write an expression for the perimeter

Perimeter = length of curved portion + length of straight portion

Perimeter = πr + 2r

Perimeter = (π + 2)r

since we are given the perimeter = 5.14, assuming that π=3.14, our equation becomes:

5.14 = (3.14 + 2)r

5.14 = 5.14 r

r = 5.14 / 5.14 = 1

Hence, diameter = 2r = 2(1) = 2 mm

(7x +6) - (5x - 4) = 180

Answers

Answer:

x= 85

Step-by-step explanation:

(7x+6)-(5x-4)=180

There is a negative 1 between the two parenthesis

-1(5x-4)

-5x+4

Now plug it back into the equation and take out the parenthesis

7x+6-5x+4= 180

2x+10=180    Now we can solve

    -10  -10

2x= 170

A photo 5 inches wide and 8 inches long is enlarged.
How wide is the new photo if it is (1)12 inches; (2)20 inches; (3)10 inches long?

Answers

Step-by-step explanation:

if the new photo is 12 inches long than the photo is enlarged

12/8=3/2

so the new photo is (3/2)*5 =15/2=7.5 inches wide.

Now,about the new photo 20 inches long it means that is enlarged 20/8=5/2 inches

so the new photo is wide 5*(5/2)=25/2=12,5 inches.

The photo 10 inches long is enlarged 10/8=5/4 inches.So the new photo is 5*(5/4)=25/4=6,25 inches wide.

Answers

Answer:

The algebraic expression for the nth term in this pattern is n^2 + 3n

Step-by-step explanation:

We want an algebraic expression for the nth term in this pattern.

Like we are told, there must be an expression that includes the term n^2

So therefore;

We need to express each of the terms to include the n^2 term

Kindly note that the n notation will represent the term number of the value we are considering. Let’s take it one after the other.

for 4; 1^2 + 3(1)

For 10; 2^2 + 3(2)

For 18; 3^3 + 3(3)

For 28; 4^2 + 3(4)

For 50; 5^2 + 3(5)

So the nth term will be;

n^2 + 3n

Answers

Answer:

The answer is "5 or 35".

Step-by-step explanation:

It also is important to understand the difference in the AP and PA predictions, and we will talk regarding their difference, and maybe we'll take the circumstances.

It is called the PA view during the process of x-ray and as the x-ray passes from its body back to both the foreground.

Its direction was its reverse throughout the AP view. Now let's understand what critical it's really. So less the distance among object and display was also created, much clears the shadow, and according to physics concepts x-ray was its light source in this instance, but we're the target. In AP display's the rear side, which means good shadow, whereas the implications of alternative give better shadow in the PA view.

If talking around the same picture, the angle difference between both the AP and the PA visual is maximum of 15-20°.

Its situation indicates a caudal angle of 20° for the AP test. So, it must be for PA:

He never saw his captors or heard them speak. The only contact he had with them was a slot at the bottom of one wall through which a tray of food was slid twice a day. From time to time, Malcolm would bend down, put his mouth near the slot, and call out to someone, anyone. He would have welcomed hearing even mean or cruel words in response to his voice, but there was never a sound. Malcolm had thought about escaping this lonely existence. There was one small window in the room, and Malcolm suspected he could just squeeze through the bars if he wiggled enough. The ground was too far below, though, for him to survive a jump, so in his little prison he stayed. 11From time to time, Malcolm would see mice scampering along the edges of his cell. At first they all looked the same, but over time he could tell them apart and knew there were four in all. He gave each one a name: Stanton, Crispin, Roderick, and Emil. He would talk to them, and often, he felt they would talk back. Malcolm sometimes had long, drawn-out conversations and even heated debates with the mice. I hear where you're coming from, Emil, he would say, but Stanton has also made some very good points. After a while, the four mice would wake him in the morning, eagerly rubbing their whiskers against his cheek, squeaking with delight when he opened his eyes. Just knowing they liked him brought joy to his otherwise dreary existence. Years passed, and Malcolm's head began balding. His beard, however, grew and grew until it was long enough to drag behind him. One day, as he was thinking of stories he could tell the mice, he remembered the story of Rapunzel and how she had used her hair as a rope. He immediately tied the tip of his beard to one of the window bars. He tucked Stanton, Crispin, Roderick and Emil into his pockets. Because he'd grown so thin, it wasn't hard to squeeze between the bars of the window. We're off to see the world, he whispered to the mice and, clinging to his own long whiskers, he began to slowly let himself down to the ground below.
