A rectangular print on the Smiths living room wall is 4 feet long and 2 feet 6 inches wide. How many inches longer is the print than it is wide?

Answer:

10.2 ft

Step-by-step explanation:

[tex]a^{2} +b^{2} = c^{2} \\8^{2} +b^{2} =13^{2} \\[/tex]

64 + [tex]b^{2}[/tex] = 169

[tex]b^{2} = 105\\[/tex]

b=[tex]\sqrt{105}[/tex]

b= 10.2469

Answer:

part B needs to change

Step-by-step explanation:

Answer:

Step-by-step explanation:

The legs of the triangle have lengths 9 and 12.  The Pythagorean Theorem says [tex](\text{hypotenuse})^2=(\text{leg})^2+(\text{leg})^2[/tex].

[tex]x^2=9^2+12^2=81+144=225\\x=\sqrt{225}=15[/tex]

Yes, these values make a Pythagorean Triple (3 integers that fit the Pythagorean Theorem)

There are infinitely many of these triples:  3,4,5   5,12,13 are examples.  The triple in this problem is 3 times the 3,4,5 triple.

x= 15

No

H²= O²+A²

x²= 9²+12²

x²= 81+144

x²= 225

x= √225

x= 15

Answer:

scalene

Step-by-step explanation:

Answer:

Scalene

Step-by-step explanation:

Equilateral means all the sides are the same.

Isosceles means only two are the same.

Scalene means none are the same.

Answer:

The shape is a triangle, not a quadrilateral.

Step-by-step explanation:

A= hbb/2 = 11·15/2 = 82.5

The area of the triangle is 82.5 yd².

Answer: It costs about 7.32 to buy enough lemons.

Step-by-step explanation:

Each lemon yields 2 tablespoons, which is equal to one fluid ounce.  

8 fluid ounces = one cup, 4 fluid ounces = half a cup

Four lemons will provide juice for one pie.

Cost of one pie = 4  0.61 =  2.44

Cost of three pies = 2.44   3 =  7.32

Step-by-step explanation: I used quick mental math.

It is not possible for a cross section of a cylinder to have a triangular shape

Cross section is the non-empty intersection of a solid body in three-dimensional space with a plane, or the analog in higher-dimensional spaces

A cylinder has traditionally been a three-dimensional solid, one of the most basic of curvilinear geometric shapes

A triangle is a shape formed when three straight lines meet

Cross section of the cylinder is depends on how we cut .The cross-section of a cylinder may be either circle, rectangle, or oval

Hence, the cross section of of a cylinder can not be a triangular shape

Answer:

x^2+4x

Step-by-step explanation:

(3x^2+10x+20)-(6x+11) = 3x^2+4x+9

(3x^2+4x+9)-(2x^2+9) = x^2+4x

The polynomial that represents the measure of the third side of the plot of land is x² + 4x.

Perimeter of a straight sided figures or objects is the total length of it's boundary.

Given two sides of a triangular plot of land.

6x + 11

2x² + 9

Perimeter = 3x² + 10x + 20

Perimeter of a triangle = Sum of the three sides

Let A represents the third side.

6x + 11 + 2x² + 9 + A = 3x² + 10x + 20

2x² + 6x + 20 + A = 3x² + 10x + 20

A = 3x² + 10x + 20 - (2x² + 6x + 20)

A = x² + 4x

Hence the measure of the third side is x² + 4x.

Answer:

The first one

Step-by-step explanation:

We need to find out how much chairs there are in each of the 7 rows, so we put it as 7c. The last row has 7 chairs, so we use an addition sign to include that. Since there are 70 chairs in total, the sum is 70.

Answer:

Step-by-step explanation:

1. In general, restrictions on rational functions refer to values of the variable that make the denominator zero. The function will be undefined in that case. On a graph, such a location will show up as a "hole" or a vertical asymptote.

__

2. If ±2 are excluded from the domain, we expect factors of (x-2)(x+2) in the denominator. That is, the denominator will have a factor of (x²-4). (There may be other factors that do not have real zeros.)

__

3. A rational expression is a fraction the same as any other. The usual rules of addition, subtraction, multiplication, and division apply. For addition and subtraction, it can be useful to identify a common denominator. For multiplication and division, that is not so essential.

Answer:

  39.375 : 65.625

Step-by-step explanation:

The meaning of "reduce" in this context is unclear. We assume you want to divide the quantity 105 into parts that have a ratio of 3 : 5. Then the smaller part will be 3/(3+5) = 3/8 of the total; the larger part will be 5/8 of the total.

  3/8 × 105 = 39 3/8

  5/8 × 105 = 65 5/8

The divided quantities are ...

Answer:

With what?

Step-by-step explanation:

Answer:

n = 6

m = 6√3

Step-by-step explanation:

Reference angle = 30°

Opposite = n

Adjacent = m

Hypotenuse = 12

✔️To find n, apply the trigonometric ratio, SOH:

Sin 30° = Opp/Hyp

Sin 30° = n/12

n = Sin 30° × 12

n = ½ × 12 = 6

✔️To find m, apply the trigonometric ratio, CAH:

Cos 30° = Adj/Hyp

Cos 30° = m/12

m = Cos 30° × 12

m = √3/2 × 12 (cos 30 = √3/2)

m = √3 × 6

m = 6√3
