Answer:

$39.36

Step-by-step explanation:

Since its 20% off that means we still have a remaining 80% so first multiply 0.8 to the 82

82x0.8= 65.6

Since there is a additional 40% off multiply by 0.4 to get the discount amount

65.6x0.4= 26.24

Subtract the discount from the price

65.6-26.24= 39.36

Answer:

The markup was 143.75%.

Step-by-step explanation:

In order to find the markup, you have to find the difference between the price the store paid for the pair of shoes and the price they sold them for, then divide that by the price they paid for the shoes and the result has to be multiplied for 100:

((78-32)/32)*100=(46/32)*100=1.4375*100=143.75%

According to this, the answer is that the markup was 143.75%.

Answer:

56

Step-by-step explanation:

If there are 70 total magazines, and 80% are womens, then you just multiply 70 * .80 = .56

Answer:

Rico Spent $6.50 on each car.

Step-by-step explanation:If you divided 52 by 8 you get 6.5 in money it would be $6.50.

My answer is reasonable because my estimate ÷ 10 = $6.50

Answer:

The answers are: 6.5$ , divided by, and 5$

Step-by-step explanation:

In order to figure out the price of each toy car, we must divide 52/8 (the total price of the toy cars divided by the number of the cars) which equals to 6.5, meaning that each toy car costs 6.5$, since they all have the same price. We know that this is a reasonable price because say we were to estimate, meaning we'd take a guess without doing any calculations. Let's say we paid 50$ in total, which is easily divided by 10, if we were to round up both numbers, we'd get 5$ each. That's close to the true answer, making it reasonable to take such a guess.

Answer:

(a)  12.96 ft²

(b)  21.5 in²

Step-by-step explanation:

(a) For the first diagram

Area of the shaded region (A) = Area of Tripezium- area of circle

A = [1/2(a+b)h]-[πr²]............... Equation 1

Where a and b are the parallel side of the tripezium respectively, h = height of the tripezium, r = radius of the circle.

From the diagram,

Given: a = 15 ft, b = 6 ft, h = 12 ft, r = h/2 = 12/2 = 6 ft.

Constant: π = 3.14

Substitute these values into equation 1

A = [12(15+6)/2]-(3.14×6²)

A = 126-113.04

A = 12.96 ft²

(b) For the second diagram,

Area of the shaded region (A') = Area of square- area of circle

A' = (L²)-(πr²)............. Equation 2

Where L = lenght of one side of the square, r = radius of the circle

From the diagram,

Given: L = 2r = (2×5) = 10 in, r = 5 in

Substitute these values into equation 2

A' = (10²)-(3.14×5²)

A' = 100-78.5

A = 21.5 in²

Answer:

4 (2a+3b)^2

Step-by-step explanation:

(4a+6b)^2 = (4a+6b) * (4a+6b) = 16a^2 +48ab + 36b^2

take 4 common factor

4 (4a^2 + 12ab + 9b^2) =  4 (2a+3b)^2

Answer:

I = $337.50

Step-by-step explanation:

I = prt

I = 4500(.025)(3)

I = 337.50

The interest earned is $337.50.

The interest on a loan or principal amount can be easily calculated using simple interest. Simple interest is a notion that is employed across a wide range of industries, including banking, finance, automobiles, and more. When you pay back a loan, the monthly interest is deducted first, and any remaining funds are applied to the principle.

Simple Interest = Principal x Interest Rate x Time/ 100

Given:

Principal= 4500

Rate= 2.5%

Time= 3 years

Using Simple Interest

SI = ( P x R xT)/100

SI = (4500 x 2.5 x 3) /100

SI = 33750/100

SI = $337.50

Hence, the interest earned is $337.50

Step-by-step explanation:

first find x

all triangles = 180°

6(x - y)

Step-by-step explanation:

Begin by switching the - to a plus. Switch the x and y in the second denominator.

5x^2              2x^2

=====      +    ======

6x - 6y          3x - 3y

Pull out the common factors in both denominators. Use the distributive property.

5x^2              2x^2

=====      +    ======

6(x - y)          3(x - y)

Multiply both the numerator and denominator by 2 on the left had fraction.

5x^2              2*2x^2

=====      +    ======

6(x - y)          2*3(x - y)

5x^2                4x^2

=====      +    ======

6(x - y)          6(x - y)

Put both numerators over a common denominator. Notice that the + sign shifts up.  It shifts up because both fractions have been changed to a common denominator.

5x^2        +        4x^2

Answer:

The cyclist can travel 0.9 miles in 2 minutes.

Step-by-step explanation:

1 hour = 60 minutes

Set up a conversion equation:

27 mi/1 hr × 1hr/60 mins

It is easier to see when writing it on paper, but the fractions are set up in a way to cancel the units out until the only units left are miles and minutes

After multiplying the numerators together and then multiplying the denominators together, you should reach the answer:

27 mi/60 mins

The cyclist can travel 27 miles in 60 minutes, but how many miles can he travel in 2 minutes?

Set up an equation:

Variable x = number of miles

27 mi/60 mins = x/2 mins

Cross multiply

27 × 2 = 60 × x

54 = 60x

Divide both sides by 60

0.9 = x

Given:

The equation is:

[tex]x^2+5x=2[/tex]

To find:

The solution of the given equation by completing the square.

Solution:

We have,

[tex]x^2+5x=2[/tex]

We need to add the square of half of the coefficient of x on both sides.

Adding [tex]\left(\dfrac{5}{2}\right)^2[/tex] on both sides, we get

[tex]x^2+5x+\left(\dfrac{5}{2}\right)^2=2+\left(\dfrac{5}{2}\right)^2[/tex]

[tex]\left(x+\dfrac{5}{2}\right)^2=2+\dfrac{25}{4}[/tex]

[tex]\left(x+\dfrac{5}{2}\right)^2=\dfrac{8+25}{4}[/tex]

[tex]\left(x+\dfrac{5}{2}\right)^2=\dfrac{33}{4}[/tex]

Taking square root on both sides, we get

[tex]x+\dfrac{5}{2}=\pm \sqrt{\dfrac{33}{4}}[/tex]

[tex]x=\pm \dfrac{\sqrt{33}}{2}-\dfrac{5}{2}[/tex]

[tex]x=\dfrac{\pm \sqrt{33}-5}{2}[/tex]

[tex]x=\dfrac{\sqrt{33}-5}{2}[/tex] and [tex]x=\dfrac{-\sqrt{33}-5}{2}[/tex]

Therefore, the solutions of the given equation are [tex]x=\dfrac{\sqrt{33}-5}{2}[/tex] and [tex]x=\dfrac{-\sqrt{33}-5}{2}[/tex].
