Please Help Me Find The Perimeter For The Composite Figure.

Answers

Answer 1

Answer:

A 10.28in

Step-by-step explanation:

Find the perimeter of the circle first. Because there are two half-circles, you can just find the circumference of one whole circle. 2πr is the formula. r is the radius. The circumference of the circle is 2π or 6.28.

Then add the two sides of the square. It is 2+2=4. Add 6.28 and 4.

A pizza pan is removed at 9:00 PM from an oven whose temperature is fixed at 425°F in a room that is constant 74°F. After 5 minutes, the pizza pan is at 300 °F



A) at what time is the temperature of the pan 130°F ?


B) determine the time that needs to elapse before the pan is 180°

Answers

Answer:

9:11:48 p.m

9.8 minutes

Step-by-step explanation:

We Obtian the slope of the relation :

Slope = Rise / Run

(0, 425) ; (5, 300)

x2 = 0 ; y2 = 425 ; x1 = 5 ; y1 = 300

(425 - 300) / (0 - 5)

125 / - 5

= - 25

The intercept :

y = mx + c

425 = - 25(0) + c

425 = 0 + c

c = 425

The equation becomes :

y = - 25x + 425

Temperature at 130

130 = - 25x + 425

130 - 425 = - 25x

-295 = - 25x

x = 11.8

9:00 + 11.8 = 9:11:48 p.m

B.)

180 = - 25x + 425

180 - 425 = - 25x

-245 = - 25x

x = 9.8 minutes

Which of the following correctly isolates the constant for the polynomial: x2 – 12x + 27

A. x^2 – 12x = 27
B. x^2 - 12x = 36
C. x^2 - 12x = -27
D. x^2 + 27 = 12x

Answers

Answer:

x^2 - 12x = -27

Step-by-step explanation:

Here, we want to isolate the constant for the polynomial

To do this, we start by setting the expression to zero

Afterwards, we can bring the constant term over the equal to sign, giving a change in sign value

Mathematically, we have this as;

x^2 - 12x + 27 = 0

x^2 - 12x = -27

31. The students are selling wrapping paper to raise money. Each roll of paper rolle for 5%,
Part A
Write m expression that represents the total amount of money, in dollars, the students raise
from selling x rolls of wrapping paper
Part B.
The goal of the students was to raise $600. They sold 6% rolls of paper. By what amount did
the students miss their goal of raising 5600? Show or explain all of your work

Answers

Answer:

So The Answer would be 600=1.05x and 600=1.06x for part A and B

Step-by-step explanation:

For Part B If there goal is to raise 600$ then 5% of 600$ = 30$ per roll of wrapping paper;

Part A: 600= 1.05x

The expression 1.05 represents the 5% increase for X wrapping paper sold to the equivalent of 600$  

For end of the Question Im unsure what they mean they "missed there goal of raising 5600?.. 5600$ or 560.0$?"

What is the slope of the line?
hurryyyy

Answers

Answer:

slope = 3

Step-by-step explanation:

if each square is equal to 1

The slope has to be 3.

you can see it, because between those 2 point you can count 3 spaces in y-vertex, and 1 space in x-vertex

what that means is that we will move 3 steps up (or down) for each 1 space in x-vertex.

you can see it just right there on the graph

a 3 inch radius circle is drawn inside a 7 in radius Circle if you throw a dart at the circles what is the probability you land inside the smaller circles​

Answers

Answer:0.82

Step-by-step explanation:

The first step is to determine the areas of the inner and the bigger circles.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the inner circle,

diameter = 148.4 cm

Radius = 3 inches

Area = 3.14 × 3² = 28.26 inches²

Considering the bigger circle,

Radius = 7 inches

Area = 3.14 × 7² = 153.86 inches²

The area between the bigger and inner circles is

153.86 - 28.26 = 125.6 inches²

Probability = number of favourable outcome/number of total outcome.

the probability you land inside the bigger circle but outside smaller circle is

125.6/153.86 = 0.82
