The difference of 3 times a number and 15 is no less than the square of the number.
Select the inequality that represents this relationship.

1/7 divided by 3 can be written as:

1         3

----  ÷  ---- =

7         1

You need to do the reciprocal of 3 so that gives you 1/3.

1         1

----  ÷  ---- =

7         3

Then multiply numerator with numerator and denominator with denominator.

1         1             1

----  ÷  ---- =   --------

7         3         21

Your final answer is 1/21.

Semicircle:

diameter  = length of the rectangle = 25 cm

Half circumference = πd/2

= 3.14 * 25/2 = 39.25 cm

Perimeter of the figure = 39.25 + 20 + 25 + 20

= 104.25 cm

Answer:

104.25 cm

Step-by-step explanation:

Perimeter = three sides + arc

Arc length: ½ × pi × diameter

½ × 3.14 × 25

39.25

Perimeter

39.25 + 20 + 25 + 20

104.25

Answer:

Madeline: y=1x+9

Issac: y=2x+1

x=8, y=17

Step-by-step explanation:

Solving for X:

Multiply Issac's by -1:

y= 1x+ 9

-y=-2x-1

Combine:

0=-x+8

Add x to both sides:

x=8

Solving for Y:

Since we already have x, we only need to input the x value into one of the formulas:

y=1(8)+9

Simplify parenthesis with multiplication:

y=8+9

Add:

y=17

If you feel unsure, check your work with both equations:

(17)=2(8)+1

17=16+1

17=17=Good

(17)=1(8)+9

17=8+9

17=17=Good

Given:

The base of the triangle = 6 ft

The height of the triangle = 5 ft

The other two side of the triangle = 5.5 ft and 5.5 ft

The height of the prism = 9 ft

To find the measurement of the fabric to make the tent.

We need to find the surface area of the triangular prism.

Formula

The surface area of the triangular prism is

[tex]SA = bh+(a+b+c)H[/tex]

where, b be the base of the triangle

h be the height of the triangle

a and c be other two sides of the triangle

H be the height of the prism

Now,

Putting,

b = 6, h = 5, a = 5.5, c = 5.5 and H = 9 we get,

[tex]SA = (5)(6)+(6+5.5+5.5)(9)[/tex] sq ft

or, [tex]SA = 30+153[/tex] sq ft

or, [tex]SA = 183[/tex] sq ft

Hence,

Based on the given dimension 183 sq ft fabric is needed to make the tent.

An algebra tile configuration with 5 tiles in the Factor 1 spot: +x², +x², +, +, +, and in the Factor 2 spot: +x², +x², +x, +x, +x, represents the factors of 4x² - 9.

In order to determine a solution for the given polynomial, we would factor it by using this quadratic form:

a² - b² = (a + b)(a - b)

4x² - 9 = 2x² - 3²

2x² - 3² = (2x + 3)(2x - 3)

Based on the calculations above, an algebra tile configuration with 5 tiles in the Factor 1 spot: +x², +x², +x, +x, +x, and in the Factor 2 spot: +x², +x², +x, +x, +x, represents the factors of 4x² - 9 as shown in the image attached below.

c=2a+3

Answer:

c = 2a + 3

Step-by-step explanation:

2c + 5 = 11 + 4a

2c = 4a + 11 - 5

2c = 4a + 6

c = 4a/2 + 6/2

c = 2a + 3

Answer:

D

Step-by-step explanation:

like it said, he used 5 instead of the actual height which is 4

Answer:

D

Step-by-step explanation:

The area of a parallelogram is denoted by: [tex]A=bh[/tex] , where b is the base and h is the height that is perpendicular to the base. Depending on what kind of parallelogram it is (square, rectangle, rhombus, regular parallelogram), that height could be the side length, but usually it is not; it is only the side length in special cases, like a square.

Here, we are given that the base is 11 and that the height is 4. Since the problem gives us two different values for the height versus the side length, we know that for this parallelogram, the height is not the same as the side length. Thus, we must use 4 for the height and 11 for the base in the area formula.

Therefore, the only answer that correctly points out this mistake is D.

Answer:

(A) [tex]sin C =\frac{4}{5}[/tex]

Step-by-step explanation:

Opposite,AB = 4,

Hypotenuse,BC = 5

Adjacent, AC = 3.

[tex]sin \theta =\frac{opposite}{Hypotenuse}\\ sin C =\frac{4}{5}[/tex]

The value of sin C, sin B, cos C, and tan B will be 4/5, 3/5, 3/5, and 3/4.

It's a form of a triangle with one 90-degree angle that follows Pythagoras' theorem and can be solved using the trigonometry function.

Right triangle ABC is shown. Side AB has a length of 4, side BC has a length of 5, and side AC has a length of 3.

Then the value of the sin C, sin B, cos C, and tan B will be

sin C = 4/5

sin B = 3/5

cos C = 3/5

tan B = 3/4

Answer:

B=119

Step-by-step explanation:

C=180-112=68

68+51=119

A=180-119=61

180-61=119

B=119

Answer:

∠ B = 119°

Step-by-step explanation:

∠ C and 112° are adjacent angles and supplementary, thus

∠ C = 180° - 112° = 68°

The external angle of a triangle is equal to the sum of the 2 opposite interior angles.

∠ B is an exterior angle of the triangle, thus

∠ B = 51° + ∠ C = 51° + 68° = 119°

Square Pyramid

Hence , the surface area of the square pyramid is 340 square feet

Step-by-step explanation:

The square pyramid has a square base

Given that the base side is 10 ft and the slant height of the pyramid is 12 ft.

The surface area of a square pyramid is SA, then

SA = Area of the base + [tex]\frac{1}{2}[/tex] × P × Sh

where P is the perimeter of the base and Sh is the slant height of the pyramid

P = 4 × 10

SA = [tex]10^{2} + \frac{1}{2}[/tex]× 40 × 12

SA = 100 + 240

SA= 340 square feet

Hence , the surface area of the square pyramid is 340 square feet

Let the number be x

x² + 2x = 3

x² + 2x - 3 = 0

Product  = -3

Sum =2

Factors = 3 * (-1)

x² + 3x - x - 3 = 0

x*(x+3) - (x + 3) = 0

(x + 3)(x - 1) = 0

Ignore x + 3 because the number is a positive number

x - 1 = 0

x = 1

Answer:

125.6 cm²

Step-by-step explanation:

Area of circle = πr²

Area of shaded region = Area of outer circle - area of the inner circle

= 3.14*7*7 - [3.14*3*3]

= 153.86 - 28.26

= 125.6 cm²

OR

= 3.14 * 7 * 7 - [3.14*3.*3]

= 3.14* [7² - 3²]

= 3.14* (7+3)(7-3)  

= 3.14* 10 * 4

= 125.6 cm²
