What is the radius of D?

Answer:

C = 2pi(r)

= 2pi(5)

≈ 31.416

≈ 31.4

Answer:

Hello! answer: 31.4

Step-by-step explanation:

I'm using 3.14 for pi and

To find circumference you just have to do diameter × pi or radius × 2 × pi since we have the radius we can just do radius × 2 × pi so

5 × 2 × 3.14 = 31.4 so our circumfrence is 31.4 Hope that helps!!

Step-by-step explanation:

[tex](2x - 5)( - {3x}^{2} + 4x - 7) \\ - {6x}^{3} + {8x}^{2} - 14x + {15x}^{2} - 20x + 35 \\ - {6x}^{3} + {8x}^{2} + {15x}^{2} - 14x - 20x + 35 \\ - {6x}^{3} + {23x}^{2} - 34x + 35[/tex]

Answer:

-6x^3 + 23x^2 - 34x + 35.

Step-by-step explanation:

(2x - 5) (-3x^2 + 4x - 7)

= 2x(-3x^2 + 4x - 7) - 5(-3x^2 + 4x - 7)

= -6x^3 + 8x^2 - 14x + 15x^2 - 20x + 35

= -6x^3 + 23x^2 - 34x + 35.

Answer:

B

Step-by-step explanation:

x2 + x -6 = (x-2)(x+3)

x = 2, -3

Answer:

Area of Top Bottom- L x W = Area so 8 x 5= 40 sq ft

Area of Front Back- L x W = Area so 3 x 8 = 24 sq ft

Area of Left side/ Right side L x W = Area so 3 x 5 = 15

Total Surface Area-  X + Y + Z = Total SA so 40 + 24 + 15 = 79

Volume- L x W x H = Volume so 8 x 5 x 3 = 120 cubic feet

Step-by-step explanation:

L being length

W being width

H being Height

Answer:

B. 3(12 - x) = 6

Step-by-step explanation:

3(20 - 10) = 44

3(10) = 44

30 < 44

3(12 - 10) = 6

3(2) = 6

6 = 6

2(10) + 3 = 25

20 + 3 = 25

23 < 25

2(10) - 3 = 22

20 - 3 = 22

17 < 22

Answer:

[tex] \displaystyle x = \frac{21y + 2}{15} [/tex]

[tex] \displaystyle y = \frac{15x - 2}{21} [/tex]

Step-by-step explanation:

remove parentheses:

[tex] \displaystyle x + 7y = 6x - \frac{2}{3} [/tex]

move x to left hand side and y to right hand side and change its sign:

[tex] \displaystyle x - 6x = -7y - \frac{2}{3} [/tex]

simplify Substraction:

[tex] \displaystyle - 5x = \frac{-21y - 2}{3} [/tex]

divide both sides by -5:

[tex] \displaystyle x = \frac{21y + 2}{15} [/tex]

move x to the right hand side and change its sign:

[tex] \displaystyle 7y = 6x - x- \frac{2}{3} [/tex]

simplify Substraction:

[tex] \displaystyle 7y =5x- \frac{2}{3} [/tex]

simplify substraction:

[tex] \displaystyle 7y = \frac{15x - 2}{3} [/tex]

divide both sides by 7:

[tex] \displaystyle y = \frac{15x - 2}{21} [/tex]

and we are done!

Answer:

x = 103⁰

Step-by-step explanation:

127+40+90+x = 360⁰

257+x = 360⁰

x = 360⁰- 257⁰

x= 103⁰

The distance between x and y on a number line will be,

⇒ |y - x|

Option B is true.

What is Number system?

A system of writing to express the number is called number system.

Given that;

x and y are two number on number line.

Now,

Since, Distance between x and y is always positive.

And, Distance between x and y is calculated as;

⇒ |y - x|

Thus, The distance between x and y on a number line will be,

⇒ |y - x|

Option B is true.

Answer:

Number 3: The answer is 31.8

Number 4: I got about 9.49ft as the answer.

Step-by-step explanation:

a^2 + b^2 = c^2

so 13^2 = 169

29^2 = 841

841+169 = 1010

the square root of 1010 is about 31.8

Step-by-step explanation:

Rectangle has four sides. The total weight of the circle is 20 grams.

A rectangle is a 2D shape that has four sides, and the pair of opposite sides are equal and parallel to each other.

As it is given that the weight of the rectangle is 80 grams, and a rectangle is made up of two triangles. Therefore, the weight of each triangle can be written as,

[tex]\text{Weight of the reactangle} = \dfrac{\text{Total weight of the reactangle}}{\text{Number of Triangles}}[/tex]

[tex]\text{Weight of the reactangle} = \dfrac{80}{2} = 40\rm\ grams[/tex]

It is given that the total weight of the triangle is double the weight of the circle. therefore, the relationship can be written as,

[tex]\text{Weight of the triangle} = 2 \times \text{Weight of the circle}[/tex]

[tex]40= 2 \times \text{Weight of the circle}\\\\\text{Weight of the circle} = 20\rm\ grams[/tex]

Hence, the total weight of the circle is 20 grams.

The number of students who collect more than one coin is 12.

A Line plot can be defined as a graph that displays data as points or check marks above a number line, showing the frequency of each value.

Given that, Mr. Petersen counted the number of coins collected by the students in his coin club and prepared the line plot.

We need to find how many students collected more than 1 coin,

Here each X represents a student,

The numbers of mark X above 2 and 3 = 4 and 8

Therefore, total students = 12

Hence, the number of students who collect more than one coin is 12.
