Find the total surface area.
A. 131.7 mi²
B. 143.4 mi²
C. 198.6 mi²
D. 99.5 mi²
Answer:
B. 143.4 [tex]\text{mi} ^2[/tex]
Step-by-step explanation:
In simple terms, surface area = adding area of all surfaces
This figure has 6 sides.
Surface area = 2 * area of trapezium + 2* area rectangle + area of bottom rectangle + area top rectangle
Surface area = 2 * ([tex](\frac{a+b}{2}) * h + 2* (l*w) + l*w + l*w[/tex])
= [tex]2 * (\frac{3+6}{2} * 2.6) + 2* (8*3) + 3*8 + 8*6[/tex]
= [tex]2 * 11.7 + 2* 24 + 24 + 48[/tex]
= 143.4 [tex]\text{mi}^{2}[/tex]

I need help with this question
A fine jewelry store leased a space at the mall with a base rent of $1,800 a month, plus 4% of all sales over $200,000. If the gross sales were $325,000, what was the total amount of rent paid by Heinz Fine Jewelry at the end of the year?
Answer:
So, first, we have to establish how much the base rent ends up costing. So to find that, we do 1,800x12=21,600. So the base rent is $21,600. Then, we add the 4% of sales which is 125,000x0.04=5,000. So, we add $21,600 with $5,000 and we get a final answer of $26,600 owed at the end of the year :)

Step-by-step explanation:
Suppose a right triangle has a
hypotenuse length of 12. If one of
the legs has length 5, what would
the length of the last leg be?
Answer:
See the last two lines below. I don't know which one you want.
Step-by-step explanation:
hypotenuse = 12
One leg = 5
other leg = x Substitute into a^2 + b^2 = c^2
x ^2 + 5^2 = 12^2
x^2 + 25 = 144 Subtract 25 from both sides
x^2 = 144 - 25 Combine
x^2 = 119 Take the square root of both sides
x = sqrt(119)
x = 10.91

Using the slope formula, find the slope of the line through the given points. (4. - 2) and ( - 2, - 2)
Hi! I'm happy to help!
To solve this problem, we have to find the slope, which is rise over run, or how much the line rises and how far forward the line goes.
We find the slope using this formula (slope formula)
m(slope)=[tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex]
This refers to the second y point minus the first y point, divided by the second x point minus the first x point. Y refers to the y axis, so that is the rise, because it is the difference of height in the line. X refers to the x axis, so that is the run, because it is the difference in how far it travels forward.
Our second y point is -2, our first y point is also -2. Our second x point is -2, and our first y point is 4. Let's plug in our values.
[tex]\frac{-2-(-2)}{-2-4}[/tex]
Let's simplify this so there isn't a double negative.
[tex]\frac{-2+2}{-2-4}[/tex]
Now, let's solve
[tex]\frac{0}{-6}[/tex]
0 divided by -6, is still 0, so there is no slope or the slope is 0. This means that the line is horizontal and the y coordinate doesn't change.
I hope this was helpful, keep learning! :D

what is the focus of x2 - 6x + 8y = -9
Answer:
(3, -2)
Step-by-step explanation:
In order to find the focus of a parabola, you must know that the equation of a parabola in a vertex form is y=a(x−h)2+k where a represents the slope of the equation. From the formula, we can see that the coordinates for the focus of the parabola is (h, k+1/4a).
What is the equation of this line in slope-intercept form?

part 2
I can't so please help me
Answer:
Step-by-step explanation:
One
2x + 3 = 8x - 5 Add 5 to both sides
2x + 3 + 5 = 8x Combine
2x + 8 = 8x Subtract 2x from both sides.
8 = 8x - 2x Combine
8 = 6x Divide by 6
x = 8/6
x = 8.333
Two
3x + 2 = 4 Subtract 2 from both sides
3x = 4 - 2
3x = 2 Divide by 3
x = 2/3
2y + 6 = 5 Subtract 6 from both sides
2y = 5 - 6
2y = -1 Divide by 2
y = - 1/2
x + y = 2/3 - 1/2
x + y = 4/6 - 3/6
x + y = 1/6

Model the situation.
The sum of two consecutive integers is 85. Find the integers that satisfy this condition.
Answer choices
A) 1 + 2 = 85
B) x+(x+1)=85
C) x+x=85
D) x+2x=85
Answer:
Option B is correct
Step-by-step explanation:
Let the number be x
Second number = x + 1
Sum = 85
x + x + 1 = 85
2x + 1 = 85
2x = 85 - 1
2x = 84
x = 84/2 = 42
Numbers are 42 and 43
Answer:
B) x+(x+1)=85
Step-by-step explanation:
Consecutive means in a row
Let x be the first integer
x+1 is the next integer
x+x+1 = 85
