Answer:

Bella do you know the distance formula?  that's the "tool" you need for these questions.  :)  Answers are bolded below  :)

Step-by-step explanation:

dist = sqrt[ x2-x1)^2 +(y2-y1)^2]

Robins house is at Point P1 = (-9,10)  in the form (x1,y1)

Sarah's house is at Point P2=(3,5) in the form (x2,y2)

dist from Robin's to Sarah's is

dist_RS = sqrt[ (3-(-9))^2 +(5-10)^2]

dist_RS = sqrt[ (3+9)^2 + (-5)^2]

dist_RS = sqrt[ 12^2 + 25 ]

dist_RS = sqrt [ 144+25]

dist_RS = sqrt [ 169]

dist_RS = 13

distance from Robin's to Jada's  

where Jada's house is at Point P3 =(-3,2) in the form (x3,y3) (we can think of this as P2 in the form (x2,y2) in our formula)

dist_R J= sqrt [ (-3-(-9))^2 + (2-10)^2 ]

dist_R J= sqrt [ (-3+9)^2 + (-8)^2 ]

dist_R J= sqrt [ (6)^2 + 64 ]

dist_R J= sqrt [ 36 + 64]

dist_R J= sqrt [ 100 ]

dist_R J= 10

distance to Madison's house

where Madison's house is at Point P4 = (-1,-5) in the form (x2,y2)

dist_RM = sqrt [ (-1-(-9))^2 + (-5-10)^2 ]

dist_RM = sqrt [ (-1+9)^2 + (-15)^2 ]

dist_RM = sqrt [8^2 + 225 ]

dist_RM = sqrt [ 64 + 225 ]

dist_RM = sqrt [289 ]

dist_RM = 17

Jada's house is 10 , Madison's is 17 so it's 7 miles farther to Madison's than to Jada's

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

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

Apothem:

radius is the same length as the base/length of each side of the hexagon.

r = 8

use pythagorean theorem to calculate the apothem

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.

The probability of getting prime number is 2/7.

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.

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.

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.

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
