Answer:
528 cm²
Step-by-step explanation:
The surface area of this prism comprises:
2 congruent triangles (the bases of the prism)2 congruent rectangles (rectangle 1 and 2) - since the triangle has 2 sides of equal length1 rectangle (rectangle 3)Area of a triangle = 1/2 × base × height
= 1/2 × 16 × 6
= 48 cm²
Area of rectangle 1 / 2 = width × length
= 10 × 12
= 120 cm²
Area of rectangle 3 = width × length
= 16 × 12
= 192 cm²
Total Surface Area = 2 triangles + 2 rectangles + rectangle 3
= (2 × 48) + (2 × 120) + 192
= 96 + 240 + 192
= 528 cm²

What is the sum of the finite arithmetic
series?
29 + 32 + 35 + 38 + 41 + ... + 59
Answers
The sum of the finite arithmetic series of 26 + 29 + 32 + 35 + 38 + 41 + 44 is 245. Arithmetic series is a sequence of number such that the difference between any term and the previous term is a constant number. When we sum a finite number of terms in the arithmetic series, we get the finite arithmetic series.
Scott and Huong each improved their yards by planting daylilies and ivy. They bought their
supplies from the same store. Scott spent $91 on 7 daylilies and 1 pot of ivy. Huong spent $105
on 7 daylilies and 3 pots of ivy. What is the cost of one daylily and the cost of one pot of ivy?
Answers
Answer:
daylilies - $12; ivy - $7
Step-by-step explanation:
one way to answer this question is by using two equations
first write your let statements
let d be daylilies and let i be ivy
7d + i = 91
7d + 3i = 105
then you can subtract the equations
you get -2i = -14
then divide eveything by -2
i = 7
ivy costs $7
lastly plug this into an equation
7d + 7 = 91
7d = 84
d = 12
daylilies cost $12

The total surface area of the composite figure will be 788 cm².
What is surface area?The total area occupied by an object's surface is referred to as its surface area. Varying 3D forms have different surface areas in geometry, which may be simply estimated using calculations.
The given pink cuboid has :
The length = 5
The width = 6
The height = 20
The surface area of pink cuboid = 500 cm²
The given purple cuboid has :
The length = 6
The width = 4
The height = 12
The surface area of purple cuboid = 288 cm²
Total surface area = The surface area of pink cuboid + The surface area of purple cuboid
Total surface area = 500 + 288 = 788 cm²
SA = 788 cm²
Thus, the total surface area of the composite figure will be 788 cm².

Calculate the portion of each mix that is peanuts, again expressing your answer as a percent. Which recipe has the greatest concentration of peanuts?
Answers
Answer:
Recipie A has a higher percentage of chocolate chips and Recipie B has a higher percentage of peanuts.
Step-by-step explanation:
Chocolate Chunks:
Recipie A calls for a total of ten cups. So 3 cups of chocolate chips are used in Recipe A. The percentage of chocolate chips in the mix is given by 3/10, which can be written as 30%. Recipie B now has a total of 20 cups. So in Recipe B 5/20, which can be written in percentages as 25%. Recipe C now has a total of 25 cups. So 6 cups of chocolate chips are used in the recipe. The percentage of chocolate chips in the mix is given by 6/25, which can be written as 24 percent. Recipie A has the highest percentage of chocolate chips of the three recipes.
Peanuts:
Recipie A calls for a total of ten cups. So, according to the recipe, A 2 cups are peanuts. The amount of peanuts in the mixture is given by 2/10, which can be written as a percentage of 20%. Recipie B calls for 20 cups. So there are 7 cups of peanuts in the recipe. The percentage of peanuts in the mix is given by 7/20, which can be written as 35%. Recipie C has a total of 25 cups, so there are 7 cups of peanuts in the recipe. The percentage of peanuts in the mix is given by 7/25, which is equivalent to 28 percent in percentages. The recipie b contains the highest percentage of peanuts of the three.
As a result, Recipie A has a higher percentage of chocolate chips and Recipie B has a higher percentage of peanuts.

Use the formula pH=log(1/[H^+]) to write an expression for the concentration of hydrogen ions in a liter of a sports drink that has a pH of 2.5.What is the concentration of hydrogen ions?
Answers
By using concepts of logarithms and powers, the concentration of hydrogen ions in a volume of a liter of a sports drink with a pH of 2.5.
How to solve a logarithmic formula
Logarithms are trascendental equations, that is, expression that cannot be described in terms of algebraic expressions. In this question we need to solve for the hydrogen ion concentration:
pH = log (1/[H⁺])
[tex]10^{pH} = \frac{1}{[H^{+}]}[/tex]
[tex][H^{+}] = 10^{-pH}[/tex]
[tex][H^{+}] = 10^{-2.5}[/tex]

4a) $26.5 because if x represents how many feet then the slope would be the price of one glulam beam.
4b) $63,600
Step-by-step explanation:
To find the answer to 4b we need to alter the equation we were given. Since x represents how many feet we buy we put 2400 in place of x.
y = 26.5 x 2,400
and we simply solve from here
y = 63,600
So, 63,600 is how much we would be spending for 2400 feet of beams. Hope this helps!!
