Answer:

68

Step-by-step explanation:

Find the scale Factor:

What do you do to 10 to make it 4?

Divide by 2.5 or Multiply by 0.4

Since, Scale factors are always written as multiplications, use x 0.4

Find the area of the smaller pentagon:

Value 1 x Scale Factor = Area of larger pentagon x 0.4 = 68.8 ≈ 68

Answer:

473/570

Step-by-step explanation:

No. of male = 365

No. of female = 570-365 = 205

No. of male with brown hair = 260

No. of female with brown hair = 108

the probability that a person was male or had brown hair = 365/570+108/570 = 473/570 [ for or case we add probabilities]

Answer:

Around 83%        473/ 570

Step-by-step explanation:

365 males  + 108 females with brown hair = 473

Divide the number of outcomes desired by the total  number of outcomes 473/570   = 0.829824....... = 82.98.....%

Answer:

I got 278 5/8

Step-by-step explanation:

the question stated square inches which I referred

to as area. You multiply both rectangles than add them together. I may be wrong but I hope this gives you a lead! :)

The total square inches of construction paper does Matthew need for his project is,

⇒ 278.63 inches²

A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.

Given that;

Matthew is cutting construction paper into rectangles for a project.

And, He needs to cut one rectangle that is 12 inches x 14 1/4 inches.

He needs to cut another rectangle that is 10 1/2 inches by 10 1/4.

Hence, We get;

Area of first rectangle = 12 x 14 1/4

                                  = 12 x 57 / 4

                                  = 171 inhces²

And, Area of second rectangle = 10 1/2 x 10 1/4

                                                = 21/2 x 41/4

                                                = 107.63 inches²

Hence, The total square inches of construction paper does Matthew need for his project is,

⇒ 171 + 107.63 inches²

⇒ 278.63 inches²

The correct option is,

⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Bella want to know what the students at her school think of her show. which is the BEST group to survey to find this information

Now, For getting accurate results she must select a random sample without bias

For this option a will not serve since she selects only students she recognizes.

Hence, Option B may not be right, as during show on the face they may not give correct opinion

And, Option C is right as a random sample is taken

And, Option D is wrong as the first 30 students may not be at random.

Thus, The correct option is,

⇒ get a list of students at her school from the office and use a random number generator to pick 30 of them.

Answer:

[tex] \displaystyle ( x_{1},y_{1}) = (0.82, - 3.18) \\ ( x_{2},y_{2}) = ( - 0.82, - 4.82)[/tex]

Step-by-step explanation:

we are given a system of quadratic and linear equation

we want to figure out x and y

in other words the coordinates where the linear function intercept quadrilateral function

to do so

you can use substitution method

since y equals to both equation so substitute:

[tex] \displaystyle {3x}^{2} + x - 6 = x - 4[/tex]

move right hand side expression to left hand side and change its sign so there's only 0 left on the left hand side:

[tex] \displaystyle {3x}^{2} + x - 6 - x + 4= 0[/tex]

simplify addition:

[tex] \displaystyle {3x}^{2} -2=0[/tex]

add 2 to both sides:

[tex] \displaystyle {3x}^{2} = 2[/tex]

divide both sides by 3

[tex] \displaystyle \frac{ {3x}^{2} }{3} = \frac{2}{3} [/tex]

[tex] \displaystyle {x}^{2} = \frac{2}{3} [/tex]

square root both sides:

[tex] \displaystyle {x} = \sqrt{\frac{2}{3} } \\ x = \frac{ \sqrt{2} }{ \sqrt{3} } [/tex]

rationalise the denominator by multiplying √3/√3:

[tex] \displaystyle x = \pm\frac{ \sqrt{6} }{3} = \pm0.82[/tex]

now let's figure out y

substitute the value of x to the linear equation:

[tex]y = \pm0.82 - 4[/tex]

when positive

[tex]y = - 3.18[/tex]

when negative

[tex]y = - 4.82[/tex]

Answer:

(x1,y1) = (0.82, - 3.18)

(x2,y2) = (-0.82, -4.82)

Step-by-step explanation:

The volume of a cone with a radius of 3.8 and a height of 7.6 is 114.92. Now let’s double them, the results come out to be 919.39, we divide these by each other and we get roughly 8 when you round. Therefore, your answer is 8.

Answer:

The correct answer Its A. 3-(11+x)

Answer:

-6

Step-by-step explanation:

g(-4) here x = -4

So, we have to take g(x) = x - 2

g(-4) = -4 -2 = - 6

g(1) , here x = 1 ,

So, we have to take g(a)= -x +1

g(-1) = -1 + 1 = 0

g(-4) + g(-1) = -6 +0 = -6

Answer:

38.11 feet

Step-by-step explanation:

all three corners of an equilateral triangle are 60°

sin 60° = 33/x

0.8660 =33/x

x = 38.11 feet

Relation between the side and the altitude of the equilateral triangle can be given as,

[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]

The length of the side of the equilateral triangle is 38.105 feet.

When all the three sides and all the three angle of a triangle are equal, then the triangle is known as Equilateral triangle.  

Relation between the side and the altitude of the equilateral triangle can be given as,

[tex]a=\dfrac{2}{\sqrt{3} } h[/tex]

Here, [tex]a[/tex] is the side of the equilateral triangle and h is the altitude of the equilateral triangle

Given information-

Altitude of the equilateral triangle is 33 feet.

Put the value of altitude in above formula to find the length of the side of the equilateral triangle. Thus,

[tex]a=\dfrac{2}{\sqrt{3} } \times33\\a=38.105[/tex]

Thus the length of the side of the equilateral triangle is 38.105 feet.
