Answer:

Well the discount with 15% off is $2.25. Now subtract 15.00-2.25 to get 12.75. You are paying $12.75 for the discounted pizza.

Step-by-step explanation:

Answer: Initially it looks like Mindy is making a profit of $0.75 plus the pizza worth $12. So it is a fair deal for Mindy. Now coming to the part of the pizza shop owner, we find that he also gains extra $2.25 from this deal. So it is a fair deal for both the shop keeper and Mindy.

The cost of the rectangular deck is: $0.08 per square foot.

Area of rectangular shape = length × width

The deck is rectangular.

Thus:

Cost of the deck per square foot = area of rectangular deck/total cost of deck.

Area of rectangular deck = 8.25 × 12.5 = 103.125

Cost of the deck per square foot = 103.125/1,270 = 0.08

Therefore, the cost of the rectangular deck is: $0.08 per square foot.

Answer:

40

Step-by-step explanation:

correct on edge

Step-by-step explanation:

l = length

w = width

l/w = 5/2

l = 5w/2

l×w = 1000ft²

(5w/2)×w = 1000

5w²/2 = 1000

5w² = 2000

w² = 400

w = 20ft

l = 5w/2 = 5×20/2 = 5×10 = 50ft

the length is 50ft.

the width is 20ft.

Answer:

16.8

Step-by-step explanation:

The scale factor is a ratio. The surface area of the real ramp is 16.80 ft².

The ratio between comparable measurements of an item and a representation of that thing is known as a scale factor in arithmetic.

As we know that the height of the real ramp is 1.2 feet, while the height of the drawing is 6 cm, therefore, the scale factor can be written as,

[tex]\rm Scale\ factor = \dfrac{\text{Area of Image}}{\text{Area of pre-image}}=\dfrac{1.2 \ feet}{6\ cm} = 0.2[/tex]

Now, the area of the pre-image can be written as,

[tex]\rm \text{Area of pre-image} = 2triangles+ 2 rectangle + 1 rectangle\ at\ base[/tex]

                             [tex]= 2(0.5 \times 6 \times 16) + 2(10 \times 9) + (16 \times 9)\\\\= 2(48)+2(90)+144\\\\= 96 + 180 + 144\\\\ = 420\ cm^2[/tex]

Further, the area of the actual ramp can be written as,

[tex]{\text{Area of pre-image}} \times \rm Scale\ factor = \text{Area of Image}\\\\ \text{Area of Image}= 420 \times (0.2)^2 \\\\ \text{Area of Image}= 16.8\ ft^2[/tex]

Hence, the surface area of the real ramp is 16.80 ft².

In the question, we are informed:

2 1/2 cups sugar for the cake and 1 1/4 cup sugar for the vanilla icing are called for in Mr. Smith's recipe.

1st step

We total the amount of sugar he'll require.

1 1/4 + 2 1/2

(1/2 + 1/4) + (2 + 1)

= 3 + (2 Plus a quarter)

a total of 3 3/4 cups of sugar

2nd Step

How many 1/4 cup sugar scoops does he require?

This can be calculated as follows:

1/4 cup sugar 3 3/4 cup sugar

= 15/4 x 1/4 = 15/4 x 1/4 = 15/4 x 1/4 =

= 15/4/4 = 15/4/4 = 15/4/4 = 15/4/4 = 15/4

15 

As a result, he'll require 15, 1/4 cup sugar scoops.

Hope this helps!!!!

Step-by-step explanation:

this is unclear.

did this mean the left and the right sides are the same length (and parallel)?

it seems then they are 2 congruent triangles and the whole shape a parallelogram.

remember, the sum of all 3 angles in any triangle is always 180°.

so,

angle 1 = 180 - 70 - 60 = 50°

the congruence principle then makes angle 3 = angle 1 = 50°.

and then angle 2 must be 70°, as 70° + angle 3 = angle 1 + angle 2.

if I misunderstood, then angle 3 and then angle 2 can't be determined.

Step-by-step explanation:

The zeros of the quadratic function f(x) = 2x² + 8x – 3 is x = -2 - √11/4 and x = -2 + √11/4

A quadratic function is in the form:

y = ax² + bx + c

Given that:

f(x) = 2x² + 8x - 3, hence:

The zero is at:

2x² + 8x - 3 = 0

2x² + 8x = 3

Dividing through by 2:

x² + 4x = 3/2

add to both sides 4:

(x + 2)² = 3/2 + 4

(x + 2)² = 11/4

x + 2 = ±√11/4

x = -2 ±√11/4

The zeros of the quadratic function f(x) = 2x² + 8x – 3 is x = -2 - √11/4 and x = -2 + √11/4

Step-by-step explanation:

Substitute the given expressions and simplify.

  f(x) -g(x) = (-2x+4) -(-6x-7)

Eliminating parentheses, we get ...

  f(x) -g(x) = 4x +11

The trajectory of your message illustrates a quadratic function

The equation of the trajectory of the message is [tex]y = -\frac 15(x - 17)^2 + 20[/tex]

The trajectory graph (see attachment) is a quadratic function that passes through the following points:

(x,y) = (7,0) and (27,0)

And the vertex is:

(h,b) = (17,20)

A quadratic function is represented as:

[tex]y = a(x - h)^2 + b[/tex]

So, we have:

[tex]y = a(x - 17)^2 + 20[/tex]

Substitute (7,0) for (x,y)

[tex]0 = a(7 - 17)^2 + 20[/tex]

Evaluate

[tex]0 = 100a + 20[/tex]

Collect like terms

[tex]100a = -20[/tex]

Divide both sides by 100

[tex]a = -\frac 15[/tex]

Recall that:

[tex]y = a(x - 17)^2 + 20[/tex]

So, we have:

[tex]y = -\frac 15(x - 17)^2 + 20[/tex]

Hence, the equation of the trajectory of the message is [tex]y = -\frac 15(x - 17)^2 + 20[/tex]

A perfect square trinomial is a quadratic equation of the form

[tex]ax^2+bx+c=0[/tex]  

and a result of squaring a binomial. This means that the first and third term of the trinomial is equal to the square of the first and second term of a binomial. Therefore, in order to determine the value of the third term, we can use the method of completing the square in which the formula is

[tex]c=(\frac{b}{2a})^2[/tex]

where c is the constant and b and a are the coefficients of the first and the second term.

The trinomial 9x^2+72x+144 is a perfect square trinomial, because it's discriminant is equal to zero
