The price of a large pizza is given by
the formula P(t) = 1.5t + 7.50, where
P(t)is the price of the pizza and t is
the number of toppings. What does
the slope represent?

Step-by-step explanation:

1. make the denominators the same.

10/15+3/15= 13/15

[tex]S_\square = 8 * 8 = 64\\S_\triangle = \frac{ah}{2} = \frac{8*3}{2} = 4 * 3 = 12\\S = S_\square - S_\triangle = 64 - 12 = 52[/tex]

Answer: 52.

Answer:

Original angle = 122*

Supplementary angle = 58*

Step-by-step explanation:

A supplementary angle is one of two angles that make up 180*

If one angle is 30*, its supplementary angle is 150*. 30 + 150 = 180.

So in this case we have two angles, the original and the supplementary angle. The original angle is 64* more than the supplementary angle. The key word is MORE.

The formula to figure it out would look like this:  x + (x + 64) = 180

x is the supplementary angle

x + 64 is the original angle (64 MORE than its supplementary angle)

180 is the total measure of the two angles because they are supplementary and we know that supplementary angles always equals 180* when added together.

Take the formula and do a little algebra.

x + (x + 64) = 180

Subtract 64 from both sides

x + x = 116

Combine the x's

2x = 116

Divide both side by 2

x = 58

Remeber we know that the original angle is 64 more than the supplementary angle, so we'll add the 64 to the value of x and we get 122.

x + 64 = 122

Check our work:

x + (x + 64) = 180

58 + 58 + 64 = 180

Given :

⠀

To Find :

⠀

Which expression is not equal to the expression shown?

3³ ÷ 3⁻⁴

Let's first solve all the equations and then check which equation is not equal to equation given in question.

⇒ 3³ ÷ 3⁻⁴ = 3³⁻⁽⁻⁴⁾

⇒ 3³⁺⁴ = 3⁷ = 2,187

⇒ 3⁻³ ÷ 3⁴ = 3⁻³⁻⁴

⇒ 3⁻⁷ = 0.000457

⇒ 3 × 3⁶ = 3⁷

⇒ 3⁷ = 2,187

⇒ 3⁷ ÷ 3⁰ = 3⁷ ÷ 1

⇒ 3⁷ ÷ 1 = 2,187

⇒ 3³ × 3⁴ = 3³⁺⁴

⇒ 3⁷ = 2,187

From the calculation of above equations, We have found that only Equation 2 ( option 1 ) 3⁻³ ÷ 3⁴ is not equal to Equation 1 ( question ) 3³ ÷ 3⁻⁴

Therefore, 3⁻³ ÷ 3⁴ ≠ 3³ ÷ 3⁻⁴

Hence, Option 1 is the correct answer.

Answer:

Step-by-step explanation:

from the pic

cos(30deg) = 4√3 / y = √3 / 2

y = 4 * 2 = 8

sin(30deg) = x/y = 1/2

x = y/2 = 8/2 = 4

ans is x = 4, y = 8

Answer:

Step-by-step explanation:

As the given triangle is a right-angled triangle,

tan(30degree) = x / (4√3) = 1/√3

x = 4

sin(30degree) = x / y = 1/2

y = 8

Answer:

12.9x-9

Step-by-step explanation:

add 5.3x and 7.6x

Answer:

12.9x-9

Step-by-step explanation:

First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self because there's no other like terms.

More examples -

5.3x+−9+7.6x

Combine Like Terms:

=5.3x+−9+7.6x

=(5.3x+7.6x)+(−9)

=12.9x+−

Answer:

Step-by-step explanation:

The first thing to notice about this problem is that you have a mixture of Metric and English units.  The first thing that I would recommend is to convert 410 miles into Kilometers

1 mile = 1.61 km

410 miles = (410*1.61) = 660 km (rounded to the nearest km)

Now you need to know the time.  The formula for travel is d=rt.  You know the distance, and you know the rate, solve the formula for time.

t=d/r.

t=660km/120km/k

t=5.5 hours.  Plus add the 2 15 minutes breaks.  2*15=30 minutes.  60 minutes in an hour means that you add 30/60 hours to the trip, or another .5 hours.

Therefore the answer is 5.5+.5 hours.

The answer is: time=6 hours.

Answer:

The perimeter is 36 cm

Step-by-step explanation:

Given;

area of the rectangle, A = 81 cm²

let the Length, = L

let the breadth = b

Perimeter, P = 2L + 2b

Area, A = Lb = 81

[tex]L = \frac{81}{b} \\\\P = 2(\frac{81}{b} ) \ + \ 2b\\\\P = \frac{162}{b} \ + \ 2b\\\\P = 162(b^{-1}) \ + \ 2b\\\\minimize \ the \ perimeter \ to \ obtain \ the \ critical \ points;\\\\P' = -162 (b^{-2}) \ + \ 2\\\\P' = \frac{-162}{b^2} \ + \ 2\\\\P' = \frac{-162 \ + \ 2b^2}{b^2} \\\\at \ critical \ points; P' = 0\\\\\frac{-162 \ + \ 2b^2}{b^2} = 0\\\\-162 \ + \ 2b^2 = 0\\\\2b^2 = 162\\\\b^2 = 81\\\\b = +/- \ \sqrt{81} \\\\b = +/- \ \ 9\\\\[/tex]

[tex]since \ the \ breadth \ will \ be \ positive \ ; b = 9 \ cm[/tex]

L = 81/9

L = 9 cm

The perimeter = 2 (L + b)

                         = 2 (9 + 9)

                         = 2(18)

                         = 36 cm

Step-by-step explanation

Y=mx+b is your equation and m=slope and b=equals y intercept

Answer:

Ix + 2I - 5 = -(x - 1)*(x - 3)

Step-by-step explanation:

In the graph, we can see two functions a red one, f(x), and a blue one, g(x)

And the equation would be f(x) = g(x)

The red one is an absolute value function, we can see that the vertex is at x = -2 and at y = -5, and it has a slope equal to 1.

Remember that for an absolute value equation with a vertex (a, b) is:

f(x) = Ix - aI + b

Then in this case, the absolute value equation is:

f(x) = Ix - (-2)I - 5

f(x) = Ix + 2I - 5

The blue equation is a quadratic equation, with roots 1 and 3, and we can see that it opens down, so the leading coefficient is negative.

Remember that for a quadratic equation with roots a and b, with leading coefficient A is:

g(x) = A*(x - a)*(x - b)

Then in this case the quadratic equation is something like:

g(x) = -N*(x - 1)*(x - 3)

Then the equation will be something like:

f(x) = Ix + 2I - 5 = g(x) = -N*(x - 1)*(x - 3)

Ix + 2I - 5 = -N*(x - 1)*(x - 3)

The only option that has this shape is the first option (the top one) such that N = 1, then:

Ix + 2I - 5 = -(x - 1)*(x - 3)

is the correct option.

Answer:

Step-by-step explanation:

A fraction consists of two parts the top number and the bottom one.

Think of the top number as the count and the bottom as the size indicator. So you have:

countsize indicator −−−−−−−−−−→proper names numeratordenominator

'~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Consider the action example of dividing 3 into 6.

We can do this division directly because their size indicators are the same. That is, we have: 61÷31. People do not normally write it this way but it is correct.

To directly divide the counts the size indicator must be the same

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

So we need to see how many of 18 will fit into 34

We can not do this directly in one operation as the size indicators are not the same.

Lets make the size indicators (denominators) the same

Multiply by 1 and you do not change the value but

1 comes in many forms.

[34×1]÷18 → [34×22]÷18

[3×24×2]÷18 → 68÷18

Now that the size indicators (denominators) are the same we can just divide the counts (numerators)

countsize indicator→[68÷18]=6÷1=6

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I could explain more showing the connection between this and the shortcut method but what I have shown you will do for now.

Step-by-step explanation:

An isosoles triangle has two congruent angles and every triangle's sum of interior angles equals 180 degrees. 138*2>180, so the 138 degree angle cannot be congruent to any of the other angles. Therefore:

Width: 16 in.,  Length:  18 in.

Step-by-step explanation:

Consecute even/odd problems seem a bit weird at first.

You choose a variable to represent the first integer, say  n .  Assume it's even (no symbolic way to tell!).  If  n  is even, then the next consecutive integer is  n + 2.  You add two because you want to skip one integer.

Width:  n

Length:  n + 2

Area is length multiplied by width, so

[tex]n(n+2)=224\\\\n^2+2n=224\\\\n^2+2n-224=0\\\\(n+14)(n-16)=0\\\\n+14=0 \text{ or } n-16=0\\\\n=-14 \text{ or }n=16[/tex]

Area of Plane Shapes-

1. Triangle Area = ½ × b × h b = base h = vertical height

2. Square Area = a2 a = length of side

Step-by-step explanation:

The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration. Surface area is the total amount of space that all of the surfaces of an object take up. It is the sum of the area of all the surfaces of that object.[1] Finding the surface area of a three-dimensional shape is moderately easy as long as you know the correct formula. Each shape has its own separate formula, so you'll first need to identify the shape you’re working with. Memorizing the surface area formula for various objects can make calculations easier in the future. Here are a few of the most common shapes you might encounter.

1

Define the formula for surface area of a cube.

2

Measure the length of one side.

3
