Lamar and Avalyn are raking leaves around a tree in their backyard. The tree has a diameter of 2 feet and is surrounded by a circle of leaves that is 24 feet in diameter. What is the area in square feet of the ground covered by leaves? Use 3.14 for π.(a) 377.94 ft² (c) 452.16 ft²
(b) 449.02 ft² (d) 530.66 ft²

please help!!!!!

Answers

Answer is (b). 449.02 sqr ft. Total area including tree and leaves will be: π r^2 = 3.14 * (12)^2 = 3.14*144 = 452.16 sqr ft Area of tree: π r^2 = 3.14 * (1)^2 = 3.14*1 = 3.14 sqr ft. So, the area covered by leaves will be: 452.16-3.14 = 449.02 sqr ft

The sum of two consecutive integers is 123 what’s is the smallest of the two integers

Answers

The smallest of the two integers is 61

Represent the consecutive numbers with x and y, where x is the smallest of the two numbers.

So, we have the following system of equations

x + y =123

y = x + 1

Substitute x + 1 for x in x + y =123

x + x + 1 =123

Subtract 1 from both sides

x + x =122

Evaluate the like terms

2x = 122

Divide both sides by 2

x = 61

Hence, the smallest of the two integers is 61

The smallest of two integers is 61

Step-by-step explanation:

Let x be the smaller integer

Then the next integer will be:

x+1

According to given statement that the sum of both is 123

$x+ (x+1) = 123\nx+x+1=123\n2x+1=123$

Subtracting 1 from both sides

$2x+1-1=123-1\n2x=122$

Dividing both sides by 2

$(2x)/(2)=(122)/(2)\nx=61$

The smallest of two integers is 61

5. What ordered pair represents they-intercept of the graph of y = x + 1?
A (0,0)
C (1,0)
B (0, 1)

Answers

Answer:

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = x + 1 ← is in slope- intercept form

with c = 1, thus

(0, 1) ← is the y- intercept
