Answer:
y=-1/2x-7
Step-by-step explanation:
y-y1=m(x-x1)
y-(-6)=-1/2(x-(-2))
y+6=-1/2(x+2)
y=-1/2x-2/2-6
y=-1/2x-1-6
y=-1/2x-7

A spherical boulder is 20 feet in diameter and weight almost 8 tons.Find its volume.Use 3.14 for T round to the nearest whole number.
Answer:
4187 ft³
Step-by-step explanation:
[tex]\frac{4}{3}[/tex]πr³
π = 3.14
r = radius
the diameter is the straight line that passes through the centre of a circle and touches the two edges of the circle.
A radius is half of the diameter
diameter = 2r
Radius = 20 / 2 = 10 feet
(4/3) x 3.14 x 10³ = 4187 ft³
seven people sit in a circle.How many ways can this be done if two people A and B sit together
Step-by-step explanation:
Suppose the persons are a, b, c, d, e, f and g.
Let us also assume that a and b always sit together.
Let us then put the remaining 5 persons in a circular arrangement. It can be done in (5–1)! = 4! = 24 ways. Now, the pair (a,b) can be placed between any two persons already placed in circular order. There are 5 such gaps. Finally the pair (a,b) can be placed in two ways viz. (a,b) and (b,a).
So, total number of ways a group of 7 persons can be seated around a circular table where 2 specified persons always sit together is 24 X 2 X 5 = 240

Step-by-step explanation:
Answer:
204 g
Step-by-step explanation:
*I thinks you have made a mistake with the unit of the volume*

The length of a rectangular garden is three feet less than twice its width.
Answer:
Width of the rectangle is 8 feet
Length of the rectangle is 13 feet
Step-by-step explanation:
Complete question -
The length of a rectangular garden is three feet less than twice its width. If the perimeter of the garden is 42 feet, what is its length?
Solution
Let the width of the rectangle be X feet
Length of the rectangle would be 2X -3 feet
Perimeter of the rectangle is 2 (length + breadth)
Substituting the given values, we get -
Perimeter = 2 (length + breadth)
[tex]42 = 2 [(2X-3) + X]\\42 = 4X - 6 + 2X\\48 = 6X\\X = 8[/tex]
Width of the rectangle is 8 feet
Length of the rectangle is [tex]2*8 -3 = 16-3 = 13[/tex] feet

If the toy store sold 5 dozen of the latest action figure, how many accessories did the store sell? Enter your answer in the box.
______ accessories
Answer:
Turbo jetpack = 6(d + 7)
Xray vision glasses = 2d - 5
Invisible shield = 10d + 1
18d + 38 ;
128 dozen accessories
Step-by-step explanation:
Let the number of boxes sold = d
Turbo jetpack = 6(d + 7)
Xray vision glasses = 2d - 5
Invisible shield = 10d + 1
Combined number of accessories sold :
6(d + 7) + (2d - 5) + (10d + 1)
6d + 42 + 2d - 5 + 10d + 1
18d + 38
If 5 dozens are sold
d = 5
Number of accessories sold :
18(5) + 38
90 + 38 = 128 dozens accessories
Which equation would demonstrate the identity property? A. (3 • 4) + (3 • 5) = 3(4 + 5) B. 3 • 5 = 5 • 3 C. 3 • 4 • 5 = (3• 4) • 5 D. 4 • 1 = 4
Answer:
D. 4 • 1 = 4
Step-by-step explanation:
In Mathematics, we have two kinds of Identity property
a) Identity property of Addition
This means that when you add a number to zero, it gives you that same number
Example: 6 + 0 = 6
b) Identity property of Multiplication,
This means that, when a number is multiplied by 1, it gives that same number.
Example: 8 × 1 = 8
Therefore, from the above question, the equation that demonstrates identity property is 4 • 1 = 4

Step-by-step explanation:
Expand the following:

(x + 1) (x + 8) = (x) (x) + (x) (8) + (1) (x) + (1) (8):
x x + 8 x + x + 8
x x = x^2:
x^2 + 8 x + x + 8
Grouping like terms, x^2 + 8 x + x + 8 = x^2 + (8 x + x) + 8:
x^2 + (8 x + x) + 8
8 x + x = 9 x:

Georgia adds two proper fractions and gets 8/7 as an answer
Work out
the two fractions.
Answer:
1/2 and 9/14
Step-by-step explanation:
Let the first fraction be 1/2
Let the second fraction be x
1/2 + x= 8/7
x= 8/7-1/3
= 16-7/14
= 9/14
Hence the two numbers are 1/2 and 9/14

what percent of 12 is 3.3?
Answer:
27.5%
Step-by-step explanation:
Hi!
To do this problem, we have to set up a percent proportion:
[tex]\frac{3.3\\}{x}[/tex] = [tex]\frac{12}{100}[/tex]
In this problem, the denominators are the percent values and the numerators are the numerical value.
x = [tex]\frac{3.3*100}{12}[/tex]
x = [tex]\frac{330}{12}[/tex]
x = 27.5%

Give each side and angle measure rounded to the nearest whole number
Answer:

M<B—> 59°
The side BC and AC and the angle B is 108 m,180 m and 59°.
What is the triangle?A triangle is a polygon that has three sides and three angles. The sum of the angle of the triangle is 180 degrees.
[tex]\rm sin \theta = \frac{P}{H} \\\\ \rm sin 31^0= \frac{a}{210} \\\\ a=108 \ m[/tex]
[tex]\rm cos \theta = \frac{B}{H} \\\\ \rm cos 31^0 = \frac{b}{210} \\\\ b=180 \ m[/tex]
The measure of the angle of triangle is 180°
∠A+∠B+∠C=180°
31°+∠B+90°=180°
∠B=59°
Hence, the side BC and AC and the angle B is 108 m,180 m and 59°.
