What is the total cost of a $12 t-shirt if the sales tax is 6.5%?
15n + 24 − 4(n − 3)+ 6 − 2n = 105
Answer:
si por que esta bien hecha
1.Distribute
1 5n+24-4(n-3(+6-2n=105
15n+24-4n+12+6-2n=105
2.Add the numbers
15n+24-4n+12+6-2n=105
15n+42-4n-2n=105
3.Combine like terms
15n+42-4n-2n=105
9n+42=105
4.Subtract 42 from both sides of equation
9n+42=105
9n+42-42=104-42
Simplify
Subtract
9n+42-42=105-42
9n=105-42
subtract again
9n=63
Divide both sides of the equation by the same term
9n=63
9n/9=63/9
Simplify
Cancel terms that are in both the numerator and denominator
9n/9=63
n=63/9
Divide the numbers
n=7
so the answer is n=7

what is ( 8x²y⁰) (-10x³y²z) answer after you multiplied the coefficient and added the exponents ??
Answer:
-80zx^5y^2
Step-by-step explanation:
Here, we want to multiply the expressions
We take the similar terms together and add the exponent
We have this as:
(8 * -10) * (x^2 * x^3) * (y^0 * y^2) + z
-80z * (x^(2+3)) * (y^(0+2))
-80z * x^5 * y^2
-80zx^5y^2

Answer:
1/5
Step-by-step explanation:
b and c = [tex]\sqrt{50}[/tex] because 10 x 5 = 50
therefore the fraction is √2/ √50
to simplify you need to simplify the √50 into a number of √2 as the top is √2
√50 = √25 x √2
= 5√2
√2/5√2 = 1/5 if you divide both top and bottom by √2

A rectangle has the height of X and the width of 7X -4
Answer:
Step-by-step explanation:
Area = x(7x-4) = 7x^2-4x
A rectangle has the height or breadth of [tex]X[/tex] and the width or length of [tex]7X -4[/tex] , then area of rectangle will be [tex](7X^2-4X)[/tex].
What is rectangle ?Rectangle is a shape with four sides and having internal angles of . Two of the sides are longer than the other two. The opposite sides of the rectangle are equal in length.
Area of rectangle [tex]= \text(Length \ * \ Breadth)[/tex]
We have,
Length [tex]=7X-4[/tex]
Breadth [tex]= X[/tex]
So, Using the above formula
Area of rectangle [tex]= \text(Length \ * \ Breadth)[/tex]
[tex]=X \ * \ (7X-4)[/tex]
[tex]=7X^2 - 4X[/tex]
So, the Area of rectangle is [tex]7X^2 - 4X[/tex] which is find out using above given formula.
Hence, we can say that a rectangle has the height or breadth of [tex]X[/tex] and the width or length of [tex]7X -4[/tex] , then area of rectangle will be [tex](7X^2-4X)[/tex].

Find and simplify an expression for the area of two rows of b squares with side lengths of b centimeters .
Answer:
2b³ cm²
Step-by-step explanation:
The Area of each square :
Area of a square = a² ; where a = side length
The side length = b
Hence, Area, A = b² = b² cm²
The total number of squares:
Number of rows * number of squares per row
2 * b = 2b
Therefore, total area :
Total number of squares * area of each square
(2b) * b²
= 2b³ cm²

Answer: 1.567 × 10⁹
Step-by-step explanation:
1.6 × 10⁹ = 1.6 × 1000000000 = 1,600,000,000
3.3 × 10⁷ = 3.3 × 10000000 = 33,000,000
1,600,000,000 - 33,000,000 = 1,567,000,000
10⁹ = 1,000,000,000
1.567 × 1,000,000,000 = 1,567,000,000

Rayna and Maya are playing the integer card game. The cards in Rayna's hand are shown below: What is the total score of Rayna's hand? Support your answer by showing your work.
Answer:
The total score of Rayna's hand is described below in details.
Step-by-step explanation:
Start at 0. Combining a positive integer is a simplistic addition. Add 3 to get 3.
Combining a negative integer is like deducting : 3 + (-5) = 3 - 5 = -2.
Add 9, using 9 steps ahead, on the number line, to get 7.
Add -6, by deducting 6, to get 1.
Rayna's total composition is 1.
As for part 2, Rayna obtaining two more cards, which doesn't change his final record ...
Unless he got 2 zeroes, or he got pair cards with different symbols but similar magnitudes, such as 1 and -1.
The sign of a number is whether it is negative or positive. The magnitude (total value) of a number is how far that amount is from zero. The magnitude of a product is never negative.
The 2 cards do not change Rayna's point total, because their influences eliminate each other out. For instance, a 1 would move him one move ahead, on the number line, and a -1 would produce him one move behind, on the number line.

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 4ft and a radius of 6ft. The tank will be made from metal (including its top and bottom). Suppose the total cost of the metal will be $14,318.40. How much will the metal cost per square foot? Use 3.14 for pi, and do not round your answer.
First find surface area.
I will skip the exact explanation and just go to it because well its the same concept as the prism.
π*6^2*2+6*2π*4
=72π+48π
=120π
Now we need to take 3.14 for pi getting about
120*3.14=376.8 square foot.
Now the total is 14318.4 dollars, so what's left is simple division.
14318.4/376.8=38
The metal cost 38 dollars per square feet :P
