1) Which expression will help you find the area of the triangular bases?
3 × 12
8 × 3
1/2 × 8 × 3
8 × 12
2) Which expressions will help you find the areas of the rectangular faces? Select all that apply.
8 × 3
8 × 5
5 × 12
8 × 12
3) Find the surface area of this net.
_____a0 square centimeters
THE NET IS DOWN BELOW FOR ALL QUESTION IT IS THE SAME NET DRAWING GOOD LUCK!
1) We want to find the area of the triangular bases, which means both shown in the net. So, normally we would divide the area by 2 (from the formula), but since we are finding the area of two triangles, that isn't necessary.
A = 8 x 3
2) There are two different sized rectangles here. One that is repeated twice and the other that is on its own. We know that A and C are the same, and if we think about how this net is folded, we can determine that the width of A and C would be 5 cm. For both sized rectangles, the length is 12 cm. For rectangle B, we can see that its width is 8 cm.
A = (8 x 12) + (5 x 12)
3) Now that we have all of the expressions needed to find the surface area, what we need to do is evaluate each of them and add them together to find the total surface area.
Triangles = 8 x 3 = 24
Rectangles = (8 x 12) + (5 x 12) = 96 + 60 = 156
Surface area = 24 + 156 = 180 square centimeters
Hope this helps! :)
Can someone find the area please?

What is the slope of 3x - 3y =5
The local pizzeria offers a choice of 2 pizzas - supreme or vegetarian, 3 sides - chips, salad
or coleslaw, and 4 drinks - juice, coke, ginger beer or water. For dinner I decide to have
1 pizza, 1 side, and 1 drink. How many possible meals do I have to choose from?
Answer:
24
Step-by-step explanation:
To determine the number of possible meal combinations at the pizzeria, multiply the number of options for each course, yielding 2 (pizzas) × 3 (sides) × 4 (drinks), which equals 24 possible meals.
Explanation:To calculate the number of possible meals you can choose from at the pizzeria, you can use the Fundamental Principles of Counting, specifically the Multiplication Principle. The principle states that if one event can occur in m ways and a second independent event can occur in n ways, then the two events can occur in m × n ways together. Since we are dealing with more than two events, we extend this principle.
In this scenario, you have 2 kinds of pizzas, 3 sides, and 4 drinks to choose from. To find the total combinations of meals, you multiply the number of options for each selection. That is:
Pizza options (2) × Side options (3) × Drink options (4) = Total meal options.So, the calculation would be:
2 × 3 × 4 = 24 possible meals.
This calculation shows that there are 24 different combinations of meals that you can choose from when you pick one pizza, one side, and one drink.

Joe is making lemonade by adding 6 5/8 cups of water. It is too strong, so he adds 1 5/8 cups more. How much water does Joe use?
Answer:
8 1/4 or 8 2/8
Step-by-step explanation:
6+1= 7
5/8+5/8= 10/8 or 1 2/8
1 2/8 + 7= 8 2/8
Simplify
8 1/4 cups
In making his lemonade, Joe uses a total of 8 1/4 cups of water. He initially adds 6 5/8 cups, then adds an additional 1 5/8 cups when the lemonade is too strong.
Explanation:Joe is making lemonade and initially adds 6 5/8 cups of water. When he finds it too strong, he adds another 1 5/8 cups of water. To calculate the total amount of water Joe uses, we add the two quantities of water together:
First, add the whole numbers: 6 + 1 = 7 cupsNext, add the fractions: 5/8 + 5/8 = 10/8 = 1 2/8 = 1 1/4 cupsAdding these results together, Joe uses a total of 7 cups + 1 1/4 cups = 8 1/4 cups of water in his lemonade.

What is the difference between the circumference of the outer circle and the circumference of the inner circle? Leave your answer in terms of π.
Diameter is 9m and the outer part of the circle is 2m
Will give brainiest
Final answer:
The difference between the circumferences of the outer and inner circles, given a diameter of 9m for the inner circle and an outer part thickness of 2m, is 4π m.
Explanation:
To find the difference between the circumferences of an outer circle and an inner circle, we first need to determine their respective radii and then apply the circumference formula C = 2πr.
The given diameter of the inner circle is 9m, hence its radius is 9m / 2 = 4.5m. The thickness of the outer part of the circle is 2m, so the radius of the outer circle is 4.5m + 2m = 6.5m.
The circumference of the inner circle is C_inner = 2π(4.5m) = 9π m, and the circumference of the outer circle is C_outer = 2π(6.5m) = 13π m.
The difference between the circumferences is therefore Couter - Cinner = 13π m - 9π m = 4π m.

When looking at the unit circle, what do you notice about the value of sine and the value of the y coordinate?
a the values are the same
C. the values are opposites
b. the absolute values are different
d. none of the above
Answer:
a. the values are the same.
Step-by-step explanation:
The sine = y-coordinate / hypotenuse. The unit circle has hypotenuse = 1, so
the sine = y /1 = y.
Final answer:
The value of the sine of an angle on the unit circle is the same as the y-coordinate of the corresponding point on the circle, as the sine function is defined as the ratio of the opposite side to the hypotenuse in a right triangle.
Explanation:
When looking at the unit circle, we can observe that the value of the sine of an angle is indeed the same as the y-coordinate of the point on the unit circle at that angle. In other words, if we take a point on the unit circle at an angle θ from the positive x-axis, its coordinates can be expressed as (cos(θ), sin(θ)). Therefore, the sine of the angle gives us the y-coordinate of the point on the circle. This relationship is a direct consequence of how the trigonometric functions are defined in the context of a right triangle, where the sine of an angle is the length of the side opposite to the angle (y) divided by the hypotenuse (which is 1 for the unit circle).

A. 22,50 zł B. 157,50 zł C. 202,50 zł D. 225 zł
Answer:
Option D: 225 zł
Step-by-step explanation:
(English question:
Mr. Bartek bought 15 flower seedlings and paid PLN 67.50 for them. Mr. Michał bought 50 cuttings at the same price for one piece.
How much more did Michał pay for seedlings than Mr. Bartek? Choose the right answer from the given ones.
A. 22.50 PLN B. 157.50 PLN C. 202.50 PLN D. 225 PLN)
We can solve this problem using a rule of three:
If Mr. Bartek bought 15 flowers seedlings for 67.5, Mr. Michal that bought 50 flowers seedlings will pay what price (If he pays the same price per unit that Mr. Bartek paid)?
15 seedlings -> PLN 67.5
50 seedlings -> PLN X
15/50 = 67.5/X
X = 50*67.5/15 = 225
The correct option is D: 225 zł

The sum of two numbers is 98. One number is 76 less than the other.
Answer:
Step-by-step explanation:
1. n + y = 98
2. n = 76 - t
Answer:
11 and 87
Step-by-step explanation:
Let's create an equation to solve this. (I know that it is just subtraction, but equations are great ways to understand concepts.)
We can represent each number as "n"
In that case, we have:
n + (n - 76) = 98
Grouping n's:
2n - 76 = 98.
Adding 76 to both sides:
2n = 174
Dividing by 2:
87.
Plug-and-chug:
87 + (87 - 76) = 98
Thus, our final answer is that one number is 11, the other 87.
The profit( in thousands ) that a company makes, t years after opening, can be found by: F(t) = 2t^2 - 6t -3
a) How many years after opening did the company’s profit switch from negative to positive? ( round to the nearest tenth)
b) How many years after opening was the company’s profit the lowest?
c) What was the company’s profit( in thousands of dollars) when it was the lowest? ( don’t use dollar signs in your answer)
a) After 4 years the profit will change from negative to positive.
b)after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) after 4 years the profit will be 5.
Step-by-step explanation:
a) After 1 year = 2(1) -6(1) -3
= 2-9
= -7
It's negative
After 2 years = 2(4) -6(2) -3
= 8-12-3
= -7
It's negative
After 3 years = 2(9) -6(3) -3
= 18 - 18 -3
= -3
It's negative
After 4 years = 2(16) -6(4) -3
= 32 -24-3
= 5
It's positive
After 4 years the profit will change from negative to positive
b) after 4 years the profit will be lowest.
Because the equation is a quadratic equation so, it will be increasing.
c) profit = 2(16) - 6(4) -3
= 32 -24 - 3
= 5
after 4 years the profit will be 5

Answer:
3y - 10
———
2
Step-by-step explanation:
The table and the graph below each show a different relationship between the same two variables, x and y:
How much more would the value of y be in the table than its value on the graph when x = 11?
(answers)
110
150
215
275
Answer:
if x = 11 then y = 660
Step-by-step explanation:
when the x increases by 1 at a constant rate, the y increases by 60 at a constant rate
so, if we keep moving forward with the table, you'll easily see that when x = 11, y = 660
The value of y would be 275 more in the table than on the graph when x = 11. Hence the correct option is 4.
The value of y would be 275 more in the table than its value on the graph when x = 11.
By substituting x = 11 into the equation y = 10 + 2x, we get y = 10 + 2(11) = 32 for the graph.
From the table, the corresponding value for y when x = 11 is 307.
Thus, the difference in the value of y between the table and the graph is 307 - 32 = 275.
