Dillon decided to construct a rectangular deck in his back yard. It is 16 feet long and 13 feet wide. He is trying to determine whether he should construct the deck using cedar or a pressure treated material.
The cedar costs $21.09 per square foot for materials.
The pressure treated material costs $18.90 per square foot for materials.
The cost for labor will be the same for either material.
How much money would Dillon save installing a deck with pressure treated material instead of cedar? Explain or show your reasoning. You may use diagrams, drawings, or equations as well as words.
PLZZZ
Answer:
He would save $455.5
You would multiply 13 by 16 to get the total area of the deck.
Then you would multiply 208 times 21.09
Then you would multiply 208 by 18.90
You would get two numbers: 4386. 72 and 3931.2
You subtract the two numbers and you get 455. 52
Step-by-step explanation:
Answer:
455.52
Step-by-step explanation:
16x13=208
Cedar:
208x21.09= 4,386.72
Pressure-treated:
208x18.90= 3,931.2
Difference
4,386.72-3,931.2= 455.52
5 + n2 > 8
A. n > 6
B. n>3
C. n>1.5
D. n < 26
Answer: n>1.5
( n2 here means 2×n not n² )
Step-by-step explanation:
5 + 2n > 8
Subtract 5 from both sides
5 -5 + 2n > 8 -5
2n > 3. Divide both sides by 2
2n/2 > 3/2
n = 1.5

Answer:
5 bracelets
Step-by-step explanation:
First, we can add the total amount of bracelets together.
4+8+3+5=20
There are 20 bracelets in all. The question asks how many bracelets each girl would get if they were distributed evenly. So, we have to find ow many girls there are.
1) Rayann
2) Jennifer
3) June
4) Tammy
To get the actual answer, we have to divide 20 bracelets by 4 girls.
20/4=5
Each girl should get 5 bracelets if the bracelets are evenly distributed.

The mass of an adult North Pacific right whale is about 70,000 kg, or 7 x 10^4 kg. The mass of a male African elephant is about 7000 kg, or 7 x 10^3 kg. About how many times more massive is the right whale than the African elephant?
A. 1 x 10^1 times
B. 1.1 times
C. 1 x 10^-1 times
D. 63,000 times
Answer:
A
I may or may not be wrong please tell me
Step-by-step explanation:
A:7,000 x 10^1 = 70,000
B:7,000 x 1.1 = 7,700
C:7,000 x 10^-1 = 700
D:7,000 x 63,000 = 441,000,000

need answer ;w; In the equation -8x+ 1/4(20x - 12) = qx - 13x - 3, what value of q makes the equation
have infinitely many solutions?
A
-10
B 0 C 3 D 10
Answer:
i think it is B
Step-by-step explanation:
If 10x = qx for all values of x, then q must be equal to 10. so, the answer is (D)
What is Equation?Two or more expressions with an Equal sign is called as Equation.
To have infinitely many solutions, both sides of the equation should be equal regardless of the value of x.
This means that the left side of the equation should simplify to a constant, and the right side of the equation should also simplify to the same constant.
Starting with the left side of the equation:
-8x + 1/4(20x - 12) = qx - 13x - 3
-8x + 5x - 3 = qx - 13x - 3 (distributing 1/4 to (20x - 12))
-3x - 3 = qx - 13x - 3 (combining like terms)
-3x = qx - 13x (subtracting 3 from both sides)
Now, let's simplify the right side of the equation:
-3x = qx - 13x
-3x + 13x = qx (adding 13x to both sides)
10x = qx
Hence, If 10x = qx for all values of x, then q must be equal to 10. so, the answer is (D)

Please help me understand this problem plz
Answer:
x∠ = 32
Step-by-step explanation:
since this is a right triangle we can tell that one angle is a right angle (that is, a 90-degree angle)
and since the outsider angle is 122 degrees the sum between the inside one and the outside one must be 180 which means it is 180 - 122 = 58
so we know that the right angle is 90 degrees, the other one is 58 and the sum of angles in a triangle is 180, x must equals 32
180 - 90 - 58
A computer technician charges a flat base fee plus an hourly rate for all repairs. Last year, she used the formula y = 18 x + 22 to determine the cost in dollars, y, of a repair that required x hours of work. If she doubles her base fee this year, what equation should she use to determine the new cost of an x-hour repair? y = 18 x + 44 y = 36 x + 22 y = 36 x + 44 2 y = 18 x + 22

A. y = 18x + 44

whats the surface area of this prism plz help.Urgent
Answer:
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration.
