A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Step-by-step explanation: A simple check for the result of each set of dimensions would give the correct answer.
The volume of a right triangular prism is derived as follows;
Volume = 1/2 * b * h * l
Where, b is the base of the triangle, h is the vertical height of the triangle and l is the length of the prism.
Note that the area of the right triangle is denoted by 1/2 * b * h, and multiplying this result by the length of the prism gives the entire depth or volume of the triangular prism. Let us examine the dimensions one after the other;
(1) A triangular prism. The triangular base has a base of 7 metres and height of 9 metres. The height of the prism is 6 metres.
Volume = 1/2 * 7 * 9 * 6
Volume = 189 cubic metres
(2) A triangular prism. The triangular base has a base of 6 metres and height of 13 metres. The height of the prism is 5 metres.
Volume = 1/2 * 6 * 13 * 5
Volume = 165 cubic metres
(3) A triangular prism. The triangular base has a base of 11 metres and a height of 8 metres. The height of the prism is 8 metres.
Volume = 1/2 * 11 * 8 * 8
Volume = 352 cubic metres
(4) A triangular prism. The triangular base has a base of 10 metres and a height of 9 metres. The height of the prism is 8 metres.
Volume = 1/2 * 10 * 9 * 8
Volume = 360 cubic metres

Please help me put the coordinates on and get the slope!
Answer:
Step-by-step explanation:
Slope
\(m=\frac{y2-y1}{x2-x1} \\\\m= \frac{3/2-(-3/2)}{3/2-(-3/2)}\\\\m=\frac{3/2+3/2}{3/2+3/2}\\ \\m=\frac{3}{3}\\ \\m=1\)
slope: m=1
y=mx+b
y=1x+0
Make a the subject of the formula:
2a+9b=4
Make w the subject of t=7w+3
Answer:
a = (4 - 9b)/2
w = (t - 3)/7
Step-by-step explanation:
2a + 9b = 4
2a= 4 - 9b
a = (4 - 9b)/2
t = 7w + 3
7w = t - 3
w = (t - 3)/7

Winston earns $140 by selling 70 hot dogs at a concession stand at school. Using the same rate for the cost of one hot dog, how many more hot dogs would Winston need to sell to earn a total of $300? Solve this problem in your notebook, and type your answer in the text box below.
Answer:
He needs to sell 530 more hotdogs :)
Step-by-step explanation:
well as you can see 70 is half of 140 so its $2 for 1 hot dog, for if you multiply 300 by 2 you get 600, but it says how many MORE do you would subtract 70 from 600 to get 530.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:Therefore, the percent change from 56 to 77 students is 37.5%.
Step-by-step explanation:
students, we can use the following formula:
percent change = ((new number - old number) / old number) x 100%
Plugging in the values given in the problem, we get:
percent change = ((77 - 56) / 56) x 100%
percent change = (21 / 56) x 100%
percent change = 0.375 x 100%
percent change = 37.5%
Therefore, the percent change from 56 to 77 students is 37.5%.
Answer: 37.5%
