for question 1
Area of Base B =45×25 = 1125 cm²
perimeter of base P = 2(45+25) = 140 cm
Height = 15 cm
Using the formula
Surface area = 2B + Ph
A = 2×1125 + 140×15= 4350 cm²
Voume = Bh = 1125×15= 16875 cm³
For question 2,
Area of base = 7× 5/2= 17.5 cm²
Perimeter of base = (7+7+7) = 21 cm
Surface area = 2B + Ph
Surface area of prism = 2×17.5+ 21×10 = 245cm²
Volume = Bh = 17.5×10 = 175 cm³

The sum of two numbers is 80. If the difference between the same two numbers is 8, find the two numbers.
Answer:
The numbers are 44 and 36
Step-by-step explanation:
n + n - 8 = 80
2n - 8 = 80
2n (- 8 + 8) = 80 + 8
2n = 88
2n/2 = 88/2
n = 44
44 - 8 = 36
What is the value of k?
Answer:
[tex]( {x}^{2} + 16x + 64) - (x + 8)(x - 4) = k(x + 8) \\ ( {x + 8)}^{2} - (x + 8)(x - 4) = k(x + 8) \\ (x + 8) - (x - 4) = k \\ k = (x - x) + (8 + 4) \\ k = 12[/tex]
Answer:
Step-by-step explanation:
a² + 2ab + b² = (a + b)²
2ab = 2 * x * 8 = 16x
x² + 16x + 64 = x² + 2* x * 8 + 8²
= (x + 8)²
x² + 16x + 8 - (x +8)(x - 4) = (x+8)² - (x+ 8) (x -4)
= (x +8)(x +8) - (x + 8)(x - 4)
(x +8 ) is common in both terms
= (x + 8) [ (x + 8) - (x - 4) ]
= (x + 8) [ x + 8 - x + 4 ]
{Combine like terms. so x + (-x ) = 0 and 8 +4 = 12}
= (x + 8) [ 12]
k = 12

Which of the following equations is an example of the Associative Property of Addition?
Answer: Choice B
(3+4) + 2 = 3 + (4+2)
=========================================
Explanation:
The general rule for the associative property of addition is
(a+b)+c = a+(b+c)
the a,b,c stay in the same order from left to right. The only thing that changes is the way we group the pair of terms. On the left side, we have a & b together with c left out. Then on the right side, we have b & c together with 'a' excluded.
Addition of any group of numbers can be done in any order, which is why this property is valid (though perhaps there's a more rigorous proof out there). For this specific problem, a = 3, b = 4, and c = 2.
Answer: I think the answer to your question is option B.

The ratio of red to blue to pink marbles is 11:8:5. If there are 40 total blues, how many
marbles are there altogether?
A. 25
B. 40
C. 55
D. 120
Answer:
D) 120
Step-by-step explanation:
if there are 40 blue marbles and the ratio of blue is 8, then the multiplier is 5
# of red marbles: 11 x 5 = 55
# of pink marbles: 5 x 5 = 25
55 + 40 + 25 = 120

For the past ten years, Michelle has been tracking the average annual rainfall in Boynton Beach, Florida by recording her data in the given table. She has concluded that the relationship can be modeled by a linear function.
Year 2004 2005 2006 2007 2008 2009 2010 2011 2012 2013
Average Rainfall(in inches) 62.33 61.8 61.27 60.74 60.21 59.68 59.15 58.62 58.09 57.56
Use the values provided in the table to create a linear graph of the data. On the graph, let x = 0 represent the year 2004. Be sure to include all proper labels on the graph.
The linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]
What are linear functions?A linear function is a graph that has a constant rate.
From the table, we have the following ordered pairs
(x,y) = (0,62.33) and (1, 61.8)
Start by calculating the slope (m)
[tex]m = \frac{y_2 -y_1}{x_2-x_1}[/tex]
So, we have:
[tex]m = \frac{61.8 -62.33}{1-0}[/tex]
[tex]m = -0.53[/tex]
The linear equation is then calculated as:
[tex]y = m(x -x_1) + y_1[/tex]
So, we have:
[tex]y = -0.53(x -0) + 62.33[/tex]
Expand
[tex]y = -0.53x + 62.33[/tex]
Hence, the linear equation that represents the table is [tex]y = -0.53x + 62.33[/tex]
