Answer:
AB = 6 units
Step-by-step explanation:
Given A(8, 3 ) and B(2, 3 )
Since the y- coordinates in both points are 3 then this is a horizontal line.
The length of AB is then the difference of the x- coordinates, that is
AB = 8 - 2 = 6 units
Question 2
A stereo that regularly costs $429.99 is on sale for 35% off. How much money will be discounted from the regular price? (Round to the nearest hundredth)
Your answer:
$35
$150.50
$394.99
Answer:
$150.50.
Step-by-step explanation:
The full price of the stereo is 429.99 which is 100%, the sale is 35%.
100 - 35 = 65%
100% = 429.99
1% = 429.99 ÷ 100 = 4.2999
35% =4.2999 x 35 = 150.4996
Estimated to 150.50

Answer:
v = $312.5
Step-by-step explanation:
Let
Value of the gem stone = v
Weight of the gemstone = w
v = k * w²
Where,
k = constant of proportionality
w = 4 carat
v = $200
v = k * w²
200 = k * 4²
200 = k * 16
200 = 16k
k = 200/16
k = 12.5
Find v when w = 5 carat
v = k * w²
= 12.5 * 5²
= 12.5 * 25
= 312.5
v = $312.5

what are the first 5 terms of 30-n^2
Answer:
29, 26, 21, 14, 5
Step-by-step explanation:
To find the first 5 terms, substitute n = 1, 2, 3, 4, 5 into the n th term formula.
30 - 1² = 30 - 1 = 29
30 - 2² = 30 - 4 = 26
30 - 3² = 30 - 9 = 21
30 - 4² = 30 - 16 = 14
30 - 5² = 30 - 25 = 5
The first 5 terms are 29, 26, 21, 14, 5

Step-by-step explanation:
Hope you find this helpful!
Answer: It does because 1/3 is equal to 2/6. in order to add them, they have to have the same denominator. and if you add 2/6 to 1/6, you get 3/6. 3/6 is also equal to 1/2, if you divide both sides by 3.

Michelle is scuba diving. Her position changes from -2.1m to -38.6m in 6 1/4 min. What is the average change in Michelle's position each minute?
Answer: 5.824 m / min
Step-by-step explanation:
Change in position = -2.1m to -38.6m
Distance = |-38.6 m - (-2.1m) |
=|-36.5| m
= 36.5 m
Time = [tex]6\dfrac14\ min=\dfrac{6\times4+1}{4}\ min[/tex]
[tex]=\dfrac{25}{4}\ min[/tex]
The average change in Michelle's position each minute = [tex]\dfrac{36.5}{\dfrac{25}{4}}\text{ m/min}[/tex]
[tex]=\dfrac{36.4\times4}{25}\text{ m/min}\\\\= 5.824\text{ m/min}[/tex]
Hence, the average change in Michelle's position each minute = 5.824 m / min

Monique and Tyrel were born on the same day. On the day they turned one year
old, Monique’s parents opened a savings account for her that earned 10% interest
per year. Starting that day, Monique’s parents put $100 in her account every
year on her birthday, stopping just after she turned six. After that, the money
remained in the account but Monique’s parents did not put in any more money.
Tyrel’s parents opened a similar savings account for him, however it wasn’t until
the day he turned six years old. Starting that day, his parents put $100 in his
account each year on his birthday, earning 10% interest per year.
Complete the two given tables to find the total amount of money in Monique’s
and Tyrel’s savings accounts. Who had the better saving strategy over 15 years?
For simplicity, round the interest to the nearest dollar for each year.

1. order the intergers {-10, -25, 25, 10, -50} from least to greatest.
2.what is the area of the rectangle?
(image provided for both questions, thank you!)
Answer:
1) (-50) <(-25) < (-10) < 10 < 25
2) 150 in^2
Step-by-step explanation:
For the first question we list the numbers according to their sign(start from negative)
For the second question we multiply height with width to find the area of the rectangle.
1. order the intergers {-10, -25, 25, 10, -50} from least to greatest. 2.what is the area of the rectangle?Answer:-
1.
we know that,
negetive numbers are smaller than positive number,
According to the question,
order the intergers {-10, -25, 25, 10, -50} from least to greatest is:-
[tex]\bold{(-50) <(-25)<(-10)<10<25 }[/tex]
2.
we know that,
Area of rectangle =length ×breath
According to the question,
lenght=15 inbreadth=10 in[tex]\bold{Area=15×10 }[/tex]
[tex]\bold{Area=150~in^{2} }[/tex]

Step-by-step explanation:
The dimensions of a rectangular building used to store tools for electrical lineman has a length of 12x+24 feet and the width of 20x-10 feet.
1.Write the expression that represents the area of the building, in terms of x.
2. Write the expression that represents the perimeter of the building, in terms of x.
3. If the perimeter is going to be 220 feet, what are the dimensions of the building.
Answer:
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet
Step-by-step explanation:
It is given that:
Length of building = 12x + 24
Width of building = 20x - 10
Area = Length * Width
Area = (12x + 24) * (20x - 10)
Area = 12x(20x - 10) +24(20x-10)
Area = [tex]240x^2-120x+480x-240[/tex]
Area = [tex]240x^2+360x-240 = 2x^2+3x-2[/tex]
Perimeter = 2 (Length + Width )
Perimeter = 2 (12x + 24 + 20x - 10 ) = 2 (32x +14 )
Perimeter = 64x + 28
Putting Perimeter = 220
220 = 64x + 28
64x = 220 - 28
64x = 192
Dividing both sides by 64
x = 3
Length = 12(3) + 24 = 36 + 24 = 60 feet
Width = 20(3) - 10 = 60 - 10 = 50 feet
Therefore,
a) Area = 2x² + 3x - 2
b) Perimeter = 64x + 28
c) Length = 60 feet and Width = 50 feet

Draw the graphs of the lines below on the same grid to find the coordinates of the point of
intersection.
y = x
y = 3x - 4
Answer:
(2,2) is the solution of the given lines.
Step-by-step explanation:
Given that,
y = x ..(1)
y = 3x-4 ...(2)
We need to find the coordinates of the point of intersection.
From equation (1) and (2).
x=3x-4
4 = 3x-x
4 = 2x
x = 2
Also,
y = 2
Hence, the coordinates of the point of intersection is (2,2).
