I need help with surface area
Answers
Answer:
Surface Area varies by object/shape.
Ask your teacher/learning helper for those formulas of surface area
Step-by-step explanation:
Surface area is the sum of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

What is the slope of the line through (-7,-2) and (−6,7)?
Answers
Answer:
slope = 9
Step-by-step explanation:
To find the slope of a line that passes through a pair of points, use the slope formula, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]. Substitute the x and y values of (-7,-2) and (-6,7) into the formula and simplify:
[tex]m = \frac{(7)-(-2)}{(-6)-(-7)} \\m = \frac{7+2}{-6+7} \\m = \frac{9}{1} \\m = 9[/tex]
So, the slope is 9.

Ashleigh can choose from one of 6 different routes to get to work. The routes are listed below.
• Main St.
• Route 6
• Hilltop Drive
• Medical Avenue
• Highway 220
• Friendship Boulevard
If she chooses one route at random, what is the probability that she will choose either Hilltop Drive or Medical Avenue to get to work?
Answers
Answer:
1 /3
Step-by-step explanation:
Total Number of routes = 6
Probability = required outcome / Total possible outcomes
Probability of any one of the routes :
Required outcome / Total possible outcomes
Probability of choosing any one of the routes = 1/6
Hence,
Probability of choosing either Hilltop. Drive or medical avenue =
1/6 + 1/6 = (1 + 1) / 6 = 2 /6 = 1/3

What is equity? What does it mean to have positive equity? What does it mean to have negative equity?
Answers
Positive equity relates to assets you own that are financed by loans. The term positive equity is most commonly used with real estate investments, but there are other asset types where positive or negative equity is a consideration. As part of your financial situation, positive equity is a component of your overall net worth.
The concept of negative equity arises when the value of an asset (which was financed using debt) falls below the amount of the loan/mortgage that is owed to the bank in exchange for the asset. It normally occurs when the value of the asset depreciates rapidly over the period of use, resulting in negative equity for the borrower.

Answer:
25.12 inches
Step-by-step explanation:
So, the formula for circumference is πd (or πr² whichever you prefer. We already have the diameter, so we do π x d, which is π x 8 inches, which is equal to 25.12 inches.
This is correct only if you use π as 3.14 hope this helps :)
Drag and drop each pair of lines to categorize them as either parallel, perpendicular, or neither.
Answers
first box is parallel
Second box perpendicular
Third box neither
Fourth box neither
Fifth box perpendicular
Sixth box is parallel
Why? Slopes of parallel lines are the same. Slopes of perpendicular lines are opposite reciprocals. (Example slope=1/2 a perpendicular line would be -2/1). Neither is just a when it’s not either parallel or perpendicular.
