Answer:

Step-by-step explanation:

It is often convenient to solve a mixture problem by letting a variable represent the quantity of the higher-concentration contributor to the mix.

__

We can let x represent the number of quarts of 80% solution needed. Then (20-x) is the number of quarts of 20% solution needed. The amount of salt in the final mix is ...

  0.80x +0.20(20-x) = 0.40(20)

  0.60x = 0.20(20) . . . . . . . . subtract 0.20(20) and simplify

  x = 20/3 = 6 2/3 . . . . . . . . . divide by 0.60; quarts of 80% solution

  (20 -x) = 13 1/3 . . . . . . . . . . amount of 20% solution needed

The teacher should mix 6 2/3 quarts of 80% solution with 13 1/3 quarts of 20% solution.

Answer:

Estimate the cost of painting a concrete patio if it is a 14 foot by 8 foot rectangle is $25.76

Step-by-step explanation:

Underline is the given:

a concrete patio if it is a 14 foot by 8 foot rectangle

area of the concrete patio: 14ft x 8ft = 112

quart of paint that covers 47 square feet costs $10.99

the cost per foot: 10.99 / 47 = $0.23

the area is 112 so multiply it by cost per foot:

112 x $0.23 = $25.76

The estimated cost of painting the concrete patio is approximately $32.97.

To estimate the cost of painting a concrete patio, we first need to calculate the total area of the patio. The patio is a rectangle with dimensions 14 feet by 8 feet, so the total area is 14 feet × 8 feet = 112 square feet.

Next, we determine how many quarts of paint are needed to cover the patio. Since each quart covers 47 square feet, we divide the total area by 47:

112 square feet ÷ 47 square feet/quart ≈ 2.38 quarts

Since we can't purchase a fraction of a quart, we'll round up to 3 quarts.

Finally, with each quart costing $10.99, the estimated cost of painting the concrete patio is:

3 quarts × $10.99/quart = $32.97

So, the estimated cost of painting the concrete patio is approximately $32.97.

Answer:

[tex]\sqrt{74}[/tex]

Step-by-step explanation:

Distance between two points

Answer:

Perimeter = 132.2 ft

Area = 766.9 ft^2

Step-by-step explanation:

Perimeter of Circle : P = 2 * pi * r

Perimeter of Rectangle : P = 2*l + 2*w

Perimeter of Circle : P = 2 * pi * 15 = 30*pi ft

Perimeter of Rectangle : P = 2*15 + 2*4 = 30 + 8 = 38 ft

Total Perimeter = 132.2 ft

Area of Circle : A = pi * r^2

Area of Rectangle = L * W

Area of Circle : A = pi * 15^2 = 225*pi ft^2

Area of Rectangle = 15 * 4 = 60 ft^2

Total Area = 225*pi + 60 = 766.9 ft^2

Answer:

Area = 996 in^2

Step-by-step explanation:

First, look at the triangle on top, well, like half of it. You can use Pythagorean theorem to find the missing side. See image. Double it to find the base of the whole triangle. Use Area of a triangle:

= 1/2 b•h

to find the area of the top (the triangle).

The 24, used for the triangle base is also the side length of the square below. See image.

Area of a square is:

Area = s^2

OR, just l×w or b×h,

all the same.

Add together the triangle area and the square's area for the final answer. See image.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

The prime factorization of the expression can be done as,

9 + (2×24)

= (3×3) + (2×2×2×2×3)

= 3 [3+(2×2×2×2)]

= 3 [3 + 16]

= 3 (19)

= 57
