A house has increased in value by 35% since it was purchased. If the current value is 648,000, what was the value when it was purchased?

Answers

Answer:

Purchase rate of the house is $480000.

Step-by-step explanation:

Let the purchase rate of the house = $p

Current value of the house = $648000

If the current rate of the house has increased by 35% of the purchase rate,

Current rate = Purchase rate +  35% of the purchase rate

648000 = p + (35% of p)

648000 = p + [tex]p\times \frac{35}{100}[/tex]

648000 = p + 0.35p

648000 = (1.35)p

p = [tex]\frac{648000}{1.35}[/tex]

p = $480000

Therefore, purchase rate of the house is $480000.

The diameter of a circle is 6 feet find its area to the nearest 10th

Answers

Answer:

The area of the circle is 113.0 ft²

Step-by-step explanation:

To solve this problem we need to use the area formula of a circle:

a = area

r = radius = 6ft

π = 3.14

a = π * r²

we replace with the known values

a = π * (6ft)²

a = π * 36ft²

a = 113.04ft²

The area of the circle is 113.04ft²

round to the nearest tenth

a = 113.04ft²  = 113.0 ft²

Step-by-step explanation:

I hope this helps. have a great dsy

Answer:

perimeter of a rectangle = 2( l+b )

perimeter = 60 inches

length = 22 inches

∴ width =

2 ( 22 + b ) = 60

22 + b = 60/2 = 30

22 + b = 30

b = 30 - 22 = 8 inches

∴ width = 8 inches

What is the area in square meters of the trapezoid below​

Answers

Given:

Bases of the trapezoid are 5.2 m and 14.6 m.

The height of the trapezoid is 7 m.

To find:

The area of the trapezoid.

Solution:

The area of a trapezoid is:

[tex]A=\dfrac{a+b}{2}\times h[/tex]

Where, a,b are bases and h is the height of the trapezoid.

Putting [tex]a=5.2,b=14.6,h=7[/tex] in the above formula, we get

[tex]A=\dfrac{5.2+14.6}{2}\times 7[/tex]

[tex]A=\dfrac{19.8}{2}\times 7[/tex]

[tex]A=9.9\times 7[/tex]

[tex]A=69.3[/tex]

Therefore, the area of the trapezoid is 69.3 square meters.

Mofor and Shanice are selling fruit for a school fundraiser. Customers can buy small boxes of oranges and large boxes of oranges. Mofor sold 12 small boxes of oranges and 3 large boxes of oranges for a total of $96. Shanice sold 6 small boxes of oranges and 6 large boxes of oranges for a total of $84. Find the cost each of one small box of oranges and one large box of oranges.​

Answers

Answer:

$6 = cost of small box

$8 = cost of large box

Step-by-step explanation:

Let s = cost of small box

     l  = cost of large box

(1)    12s + 3l = 96            (2)     6s + 6l = 84

    Multiply by -2                     -24s - 6l = -192

                                                -18s   = - 108

                                                     s = $6 = cost of small box

      12(6) + 3l = 96

         72 + 3l = 96

                 3l = 24

                   l = $8 = cost of large box

What are the solutions to the equation (10−x)(3x−9)=0?

Answers

Answer:

10−x)(3x−9)=0

−3x2+39x−90=0

−3(x−3)(x−10)=0

x=3 or x=10

The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.

Given that the equation (10 - x)(3x - 9) = 0

The factors will have the form (ax + b)(cx + d), where a, b, c, and d are constants.

To find values for a, b, c, and d such that (ax + b)(cx + d) is equal to 0

To determine the solutions of (ax + b)(cx + d),  equate each term to zero and solve for x which gives the solutions.

The two solutions of (ax + b)(cx + d) are -b/a and -c/d.

To find the solutions to the equation (10 - x)(3x - 9) = 0, set each factor equal to zero and solve for x.

Setting (10 - x) = 0 gives:

10 - x = 0

To isolate x, subtract 10 from both sides of the equation:

10 - x - 10 = 0 - 10

Simplifying gives:

-x = -10

Multiplying both sides by -1 to solve for x:

(-1)(-x) = (-1)(-10)

x = 10

So, one solution is x = 10.

Now, setting (3x - 9) = 0, gives:

3x - 9 = 0

To isolate x, we add 9 to both sides of the equation:

3x - 9 + 9 = 0 + 9

Simplifying gives:

3x = 9

Dividing both sides by 3 to solve for x:

(1/3)(3x) = (1/3)(9)

x = 3

Therefore, the second solution is x = 3.

The solutions to the equation (10 - x)(3x - 9) = 0 are x = 10 and x = 3.

The probability of getting prime number is 2/7.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Outcome = 4, 5, 6, 6, 7, 8, 9.

Number of outcome = 7.

a) The prime numbers from the outcome are 5 and 7.

So, the probability of getting prime number

= 2/7

Hence, the probability is 2/7.
