Help me what is the answer?!

Answer:

x = 11

Step-by-step explanation:

Since they are vertical angles, the angles are equal. Set them equal and solve for x.

5x + 10 = 7x - 12               Subtract 5x from both sides

10 = 2x - 12                       Add 12 to both sides

22 = 2x                             Divide by 2

11 = x

There are 6 numbers on a die.

The probability of rolling a 6 would be 1/6 for each time you roll the die.

Multiply the number of rolls by 1/6.

30 rolls x 1/6 probability = 5 times.

Answer:

A. all three rectangular faces have the same surface area

B. the surface area of each rectangular face is  [tex]66\ cm^{2}[/tex]

D. the surface area of one base is [tex]15.6\ cm^{2}[/tex]

Step-by-step explanation:

Verify each statement

case A) all three rectangular faces have the same surface area

The statement is true

Because, the equilateral triangle has the three equal sides and the three equal internal angles.

case B) the surface area of each rectangular face is  [tex]66\ cm^{2}[/tex]

The statement is true

Because, the area of each rectangular face is equal to

[tex]6(11)=66\ cm^{2}[/tex]

case C) the combined surface area of both bases is greater than the surface area of one rectangular face

The statement is False

Because

The combined surface area of both bases is [tex]2[\frac{1}{2}(6)(5.2)]=31.2\ cm^{2}[/tex]

The surface area of one rectangular face is [tex]66\ cm^{2}[/tex]

therefore

[tex]31.2\ cm^{2}< 66\ cm^{2}[/tex]

case D) the surface area of one base is [tex]15.6\ cm^{2}[/tex]

The statement is True

Because

The surface area of one base is [tex]\frac{1}{2}(6)(5.2)=15.6\ cm^{2}[/tex]

Answer:

Are needed [tex]863.5\ in^{2}[/tex] of blue tile

Step-by-step explanation:

we know that

To find how much blue tile do you need, subtract the area of the smaller circle from the area of the large circle

step 1

Find the radius of the large circle

The circumference of the circle is equal to

[tex]C=2\pi r[/tex]

we have

[tex]C=113.097\ in[/tex]

substitute and solve for r

[tex]113.097=2\pi r[/tex]

[tex]r=113.097/(2\pi)[/tex]

assume

[tex]\pi=3.14[/tex]

[tex]r=113.097/(2(3.14))=18\ in[/tex]

step 2

Find the area of the large circle

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=18\ in[/tex]

substitute

[tex]A=\pi (18)^{2}=324\pi\ in^{2}[/tex]

step 3

Find the area of the smaller circle

[tex]A=\pi r^{2}[/tex]

we have

[tex]r=7\ in[/tex]

substitute

[tex]A=\pi (7)^{2}=49\pi\ in^{2}[/tex]

step 4

Find the difference of the areas

[tex]324\pi\ in^{2}-49\pi\ in^{2}=275\pi\ in^{2}[/tex]

assume

[tex]\pi=3.14[/tex]

[tex]275(3.14)=863.5\ in^{2}[/tex]

Answer:

= 2√3 m  or 3.464

Step-by-step explanation:

Using the sine,  

sin(60”)  = x / 4   multiply both sides by 4

4 sin (60°)   = x

4 * √3 / 2  =  x  

x = 2√3 m  

slant height  =2√3 m

Answer: The slant height is 2√3 meters.

Step-by-step explanation: The side adjacent to the 60 degree angle in the right triangle consisting of x, the lateral edge, and half of the base edge is half of the base edge, 2m. The side opposite of that angle is x. So basically you have tan(60°) = x/(2m)*tan(60°) = x = 2√3m. So thus the slant height is 2√3 meters.

7.8 is the distance from n to lm

Answer:

E. 7.8

Step-by-step explanation:

We have been given an image of a triangle and we are asked to find the distance from point N to line LM.

We can see that NO is the altitude for our given triangle, so the distance from point N to line LM will be equal to length of segment NO.

We can see from our given attachment that length of segment NO is 7.8 units, therefore, option E is the correct choice.

1 centimeter is equivalent to 10 millimeters . Therefore, 45 centimeters will be equivalent to;

45*10 = 450 millimeters

Answer:

450 mm

Step-by-step explanation:

Given in the question,

the length of an average cat's body = 45 cm

To find,

number of mm which are equivalent to 45 cm

We know that

1 cm = 10 mm

45 cm = 45 x 10 mm

           = 450 mm

Hence, there are 450 mm in 45 cm.

The cost of 4 notebooks should be 24.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio.

Given that,

Price of 2 notebooks = $12

Price of 3 notebooks = $18

And the price of 5 notebooks = $30

To determine the price of 4 notebooks,

First find the price of 1 notebook = 12 / 2 = 6

The price of 4 notebooks = 6 x 4 = 24

The required price of 4 notebooks is $24.

The scale factor is obviously 7, because the 28 divided by 4 equals 7.

This means that the larger octagon's perimeter will be 7 times the smaller octagon's perimeter.

So 34 * 7 = 238.

To find the perimeter of a larger octagon, add up the lengths of all its sides. The formula for finding the perimeter of any regular polygon is P = ns, where P is the perimeter, n is the number of sides, and s is the length of one side.

An octagon is a polygon with 8 sides. To find the perimeter of an octagon, you need to add up the lengths of all its sides. If you know the length of one side of the octagon, you can multiply it by 8 to get the perimeter. For example, if the length of one side is 5 cm, the perimeter of the octagon would be 5 cm x 8 = 40 cm.

ANSWER

[tex](f\circ g)(x) = - 3 {x}^{4} - 7[/tex]

It was given that;

[tex]f(x) = - 3x - 7[/tex]

and

[tex]g(x) = {x}^{4} [/tex]

We want to find the composite function,

[tex](f\circ g)(x) = f(g(x))[/tex]

[tex](f\circ g)(x) = f( {x}^{4} )[/tex]

We plug in x⁴ into f(x)=-3x-7 to obtain:

Answer:

58.6

Step-by-step explanation:

To find the area of the figure by splitting it into two shapes - a trapezoid and a rectangle.

The area of a rectangle is A = b*h where b = 8 and h = 4.

So the area is A = 8*4 = 32

The area of a trapezoid is A = 1/2 (a+b)h where a = 8 and b = 5.3 and h = 4.

So the area is A = 1/2(8+5.3)*4 = 1/2(13.3)(4) = 26.6.

The area of the whole figure is these two areas added together.

32 + 26.6 = 58.6

Step-by-step explanation:

Given in the question,

number of people to be choose with at least 5 women in it = 8

There are 2 ways to choose 8 members

1)

5 women

(6C5)(10C3)

6x120

720

2)

6 women

(6C6)(10C2)

1x45

45

Our final answer is 720 + 45 = 765 ways

Formula to calculate

nCr = n! / r!(n-r)!

The selection of members of the committee is an illustration of combination.

The number of ways of selection is 765

The given parameters are:

[tex]\mathbf{Men = 10}[/tex]

[tex]\mathbf{Women = 6}[/tex]

At least 5 women means that:

So, the possible selection is:

[tex]\mathbf{Selection = ^6C_5 \times ^{10}C_3 + ^6C_6 \times ^{10}C_2}[/tex]

Apply combination formula

[tex]\mathbf{Selection = \frac{6!}{5!1!} \times \frac{10!}{7!3!} + \frac{6!}{6!0!} \times \frac{10!}{8!2!}}[/tex]

[tex]\mathbf{Selection = 6 \times 120 + 1 \times 45}[/tex]

[tex]\mathbf{Selection = 720 + 45}[/tex]

[tex]\mathbf{Selection = 765}[/tex]

Hence, the number of ways of selection is 765
