Answer: The equation is w*(w-3)= 180 & Alex is 15 years old

Step-by-step explanation:

Alex= w years old

Claudia= (w-3) years old

a) Equation, w*(w-3)= 180

b) Now,

         w*(w-3)= 180

      ⇒ w²-3w-180= 0

      ⇒ (w+12)*(w-15)= 0

      ⇒ w= 15

Alex is 15 years old

Claudia is (15-3) = 12 years old

Answer:

The range is [0,37.5]

Step-by-step explanation:

We start by writing the equation that links x and y

From the question;

y = 7.5x

Now, she has enough material to make 5 only

When we talk of range, we are referring to the values on the y-axis

So the lowest y value is 0

and since the highest number of bracelets is 5;

The total cost of the 5 is 7.5(5) = 37.5

So the range is [0,37.5]

Answer:

1152

Step-by-step explanation:

You multiply the 12800 films by 9% to get your answer.

Answer:

1152

Step-by-step explanation:

Step 1: Our output value is 9.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$9=100\%$.

Step 4: Similarly, $x=12800\%$.

Step 5: This results in a pair of simple equations:

$9=100\%(1)$.

$x=12800\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{9}{x}=\frac{100\%}{12800\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{9}=\frac{12800}{100}$

$\Rightarrow x=1152$

Therefore, $12800\%$ of $9$ is $1152$

this took a really long time

Answer:

4 Soccer balls and 6 Basketballs

Step-by-step explanation:

You can solve this problem by setting up a system of equations. Letting x be Soccer balls and y be Basketballs. Remember, Money goes with, Money goes with Money, meaning that for this problem the first equation that can be made is $248 = $28y + $20x with Y being basketballs and x being soccerballs. Next is a little more difficult. You will be creating the equation y=3x-6 because it is 6 less than 3 times the amount of x or Soccer balls. From here you can plug in the equations into a graphing calculator and graph it and see where the two lines intersect. This would be at (4, 6). When I said to let x equal Soccer Balls and y equal basketballs that is where I got the 4 soccer balls and 6 basketballs.

Answer:

You need to invest at a continuous compound interest rate of 6.701355026%

Step-by-step explanation:

The formula to use is the compound interest formula:A=P(1+r/100)^t

where A=Total amount at the end of the investment period

P=Principal amount

R=Rate of interest

T=Investment tenor/time

Now,

350,000=50000(1+r/100)^30 is what needs to be simplified to 6.701355026%

Answer:

Step-by-step explanation:

Given the conversion factor;

2inches = 30feet

if the height of the building is 180feet, we are to find the height of the scale model in inches.

Let x = 180 feet.

Equating both;

2inches = 30feet

x inches = 180feet

Cross multiply;

30 * x = 2 * 180

30x = 360

x = 360/30

x = 12inches

Hence the height of the scale model in inches is 12inches

Answer: 60 in

Step-by-step explanation:Let x = 180 feet.

Equating both;

2 inches = 30 feet

x inches = 180 feet

Cross multiply;

30 * x = 2 * 180

30 x = 360

x = 360/30

x = 60 inches

Answer:

70000

Step-by-step explanation:

Your inequality has one solution which is p = 1/4

The shape that would not fit this description is a trapezoid.

It is a quadrilateral that has one pair of parallel sides and a height.

The area is calculated as 1/2 x the sum of the parallel sides x height.

Examples:

Area of a trapezium that has the parallel sides as 3 cm and 4 cm and a heght o 5 cm.

Area = 1/2 x (3 + 4) x 5

Area = 1/2 x 7 x 5

Area = 35/2 = 17.5 cm^2

We have,

A parallelogram is a four-sided shape where opposite sides are parallel and congruent.

If a parallelogram has diagonals that are congruent, it must be a rectangle.

Therefore, the shape that would not fit this description is any shape that is not a rectangle.

Out of the shapes given,

A trapezoid is not a rectangle and does not have diagonals that are congruent.

Therefore,

The shape is a trapezoid.

The perimeter of the given rectangle is, 19.2112

Given that, the vertices of the rectangle are A(-3,-2), B(-5,-5), C(1,-5), D(3,-2) .

to find the perimeter through the given vertices, we need to calculate the distance from the vertices AB,BC,CD,DA.

we already know that the sum of all sides of the rectangle is known as the perimeter of the rectangle.

Using distance formula between 2 vertices , √[(x2-x1)²+(y2-y1)²]

AB = √[(-5+3)²+(-5+2)²]

     = √[(-2)²+(-3)²]

     =  √[4+9]

     =  √[13]

     =  √13

AB = 3.6056

BC = √[(1+5)²+(-5+5)²]

     = √[(6)²+(0)²]

     =  √[36+0]

     =  √[36]

     =  √36

BC = 6

CD = √[(3-1)²+(-2+5)²]

     = √[(2)²+(3)²]

     =  √[4+9]

     =  √[13]

     =  √13

CD = 3.6056

DA = √[(-3-3)²+(-2+2)²]

     = √[(-6)²+(0)²]

     =  √[36+0]

     =  √[36]

     =  √36

DA = 6

Therefore perimeter of the rectangle with given vertices is ,

  = AB+BC+CD+DA

  = 3.6056+6+3.6056+6

  = 19.2112

  = 19 (rounded to nearest tenth).

Therefore the perimeter of the rectangle with given vertices is 19.2112
