Answer:

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]

The negative solution makes no sense, so use n = 16

Width: 16

Length: 18

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

Step-by-step explanation:

Multiply the first equation by 2 and add.

Answer: your slope would be 3

Answer:

C. (4 , 3)

Step-by-step explanation:

We are given a system of equations and are asked to find its coordinate value.

To solve, we can keep in mind that both start with y, therefore meaning that we can replace one of the y's with one of the equations.:

[tex]y=\frac{1}{4}x+2\\y=x-1[/tex]

[tex]\frac{1}{4}x+2 = x-1[/tex]

Let's try to get x alone, first subtract 2 from both sides:

[tex]\frac{1}{4}x=x-3[/tex]

Now subtract x from both sides:

[tex]-\frac{3}{4}x=-3[/tex]

Now since the denominator is 4, multiply both sides by 4:

[tex]-3x=-12[/tex]

Lastly, divide both sides by -3 to get x :

[tex]x=4[/tex]

Now that we know x is 4, we can substitute 4 for x in both equations:

[tex]y=\frac{1}4(4)+2\\y=(4)-1[/tex]

[tex]y= 3\\y= 3[/tex]

Y is equal to 3, therfore, our coordinate value is C. (4,3)

Answer:

[tex] m\angle N = 32\degree [/tex]

[tex] m\widehat {NQ}=106\degree [/tex]

Step-by-step explanation:

By inscribed angle theorem:

[tex] m\angle N = \frac{1}{2} \times m\widehat {MP} [/tex]

[tex] m\angle N = \frac{1}{2} \times 64\degree [/tex]

[tex] m\angle N = 32\degree [/tex]

Again by inscribed angle theorem:

[tex] m\angle P= \frac{1}{2} \times m\widehat {NQ} [/tex]

[tex] 53\degree = \frac{1}{2} \times m\widehat {NQ} [/tex]

[tex] 2\times 53\degree = m\widehat {NQ} [/tex]

[tex] m\widehat {NQ}=106\degree [/tex]

Answer: 0.474 miles

Step-by-step explanation:

First find out how fast they can run per minute.

Phil runs 3/8 miles in 7 minutes:

Speed = Distance / Time

= 3/8 ÷ 7

= 0.0536 miles/minute

Joe runs 5/8 miles in 9 minutes:

Speed = 5/8 ÷ 9

= 0.0694 miles per minute

In 30 minutes, Phil will run:

= Miles per minute * Time

= 0.0536 * 7

= 1.608 miles

Joe will run:

= 0.0694 * 30

= 2.082 miles

Difference:

= 2.082 - 1.608

= 0.474 miles

[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]

Step-by-step explanation:

Answer:

2 21 degree angles

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:

180=138+2x

42=2x

21 degrees=x

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 :

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.

An equivalent expression of (33 x 66) - 3 is 2175.

The abbreviation PEMDAS is used to indicate the sequence of steps to be taken when resolving expressions with multiple operations. P is for "parentheses," E is for "exponents," M is for "multiplication," D is for division, A is for addition, and S is for subtraction.

Given:

We have an expression,

(33 x 66) - 3.

Solving further by using PEMDAS,

33 x 66 = 2178

Now,

(33 x 66) - 3,

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.

Define the formula for surface area of a cube.

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
