Answer:

length of the longest pencil that can fit must be less than 13cm

Step-by-step explanation:

To get the longest pencil that fit the case, we will use the pythagoras theorem;

diameter = 10cm

radius = 10/2

radius = 5cm

Height = 12cm

Get the length of the longest side

l² = r²+h²

l² = 5²+12²

l² = 25 + 144

l² = 169

l = √169

l = 13cm

Hence the length of the longest pencil that can fit must be less than 13cm

Answer:

V = 400 ft^3

Step-by-step explanation:

The area of the base of this regular square pyramid is (10 ft)^2, or 100 ft^2.

Recalling that the area of a pyramid is V = (1/3)(base area)(height), in this case we get V = (1/3)(100 ft^2)(12 ft)  =  400 ft^3

Answer:

[tex]x=8[/tex]

Step-by-step explanation:

[tex]x+9+3x=4x+2(x-3.5)[/tex]

Distribute 2 to the parenthesis

[tex]x+9+3x=4x+2x-7[/tex]

Combine like terms

[tex]4x+9=6x-7[/tex]

Subtract 4x from both sides

[tex]4x+9=6x+-7[/tex]

[tex]-4x[/tex]        [tex]-4x[/tex]            

[tex]9=2x+-7[/tex]

[tex]2x+-7=9[/tex]

Add 7 to both sides

[tex]2x+-7=9[/tex]

        [tex]+7[/tex]    [tex]+7[/tex]

[tex]2x=16[/tex]

Divide both sides by 2

[tex]2x=16[/tex]

[tex]/2[/tex]      [tex]/2[/tex]

[tex]x=8[/tex]

Hope this helps!

Answer:

Hi, there your answer is C

Step-by-step explanation:

You have to rewrite as rational [tex]2x^{\frac{4}{3} }[/tex]exponents

Use this to help you rememeber

[tex]\sqrt[n]{a^{x} } =a^{\frac{x}{n} }[/tex]

Hope this helps :)

Answer:

2[tex]x^{\frac{4}{3} }[/tex]

Step-by-step explanation:

Using the rule of exponents/ radicals

[tex]\sqrt[n]{x^{m} }[/tex] = [tex]x^{\frac{m}{n} }[/tex] , then

2[tex]\sqrt[3]{x^{4} }[/tex]

= 2[tex]x^{\frac{4}{3} }[/tex]

Answer:

(7.8, ∞)

Step-by-step explanation:

Given the inequality :

x > 7.8 ; the inequality can be explicitly interpreted as x greater than 8 ; this means that the inequality holds for all values of x above 7.8

The interval for which the inequality holds true is :

x > 7. 8 - - - > (7.8, ∞)

Answer:

b. -1/3

Step-by-step explanation:

a/4=2/3

a=8/3

(a-4)/4

(8-12)/12

=-4/12

=-1/3

Answer:

-1/3

Step-by-step explanation:

a/4=2/3

Multiply each side by 4

a/4 *4=2/3 *4

a = 8/3

(a-4)/4

(8/3 - 4) /4

Getting a common denominator

(8/4 - 12/3) /4

(-4/3)/4

-1/3

Answer:

  (b)  36 in²

Step-by-step explanation:

The right triangle at lower right has a vertical leg of 3 and a hypotenuse of 5. Then the horizontal leg is ...

  √(5² -3²) = √16 = 4

Then the horizontal diagonal is 4+4 = 8. The vertical diagonal is 6+3 = 9. The area is half the product of the diagonals, so is ...

  A = 1/2(d1)(d2) = 1/2(8 in)(9 in) = 36 in²

__

You could figure the areas of the triangles separately, but you would come to the same result. This formula is good for a rhombus or a kite (or a square, which is also a rhombus), because the diagonals are perpendicular to each other.

Answer:

The volume of the cylinder is 942 cubic kilometer.

Step-by-step explanation:

Height of the cylinder, h = 12 km

radius of the cylinder, r = 5 km

The volume of cylinder is given by

[tex]V=\pi r^2h\\\\V = 3.14\times 5\times 5\times 12\\\\V =942 km^3[/tex]

Answer:

The answer is D) Undefined because the equation is x=-11.

Answer:

h(- 4) = - 23

Step-by-step explanation:

To evaluate h(- 4) substitute x = - 4 into h(x) , that is

h(- 4) = 5(- 4) - 3 = - 20 - 3 = - 23

h (-3) = 57

Answer:

D

Step-by-step explanation:

-(-4)=+4

so it is -20+4

Answer:

D) -20 + 4 is the answer.

Step-by-step explanation:

1) Record the terms .

[tex]4 - 20[/tex]

2) Use this rule: a - b = -(b - a)

[tex] - (20 - 4)[/tex]

3) Use algorithm method.

(see the attached picture)

4) After simplifying, we have:

[tex] -(20 - 4) = - 16[/tex]

5) therefor, -20 + 4 = -16

[tex] - 16[/tex]

Answer:

1.) At times, designing a good structure with a specific function may often be difficult. If the structure is not well-designed or strong enough for the function it will not properly work. So in order for the design to be well-built, both the structure and function must cooperate.

2.) Symmetry is a balanced arrangement on the opposite sides of a structure. In order for for a structure to be stable and properly work without complications, it most commonly needs to be symmetrical. This is a very important part of designing a structure.

3.) If the structure cannot withstand the function nor the possible forces that it may encounter. It is likely that it will break or even be completely destroyed.

4.) Shape, line, color, texture, movement, space. The designer may have taken into consideration whom the desk may be used by for the shape and space. Color, texture, and line may have been based on the environment (ex. A carpenter, student, computer desk) it would be in. Although the designer may not have an exact knowledge of where the desk would be, he still could consider what the desk could "possibly" be used for. Once again, the designer could take into consideration the user, for the movement of the desk. If the desk was to be moved around on wheels, or possibly could even fold. The designer must take into consideration EVERY detail.

6.) When people design something, often times you do not know how well that design is going to work without testing it with a prototype. Yes, prototypes are expensive. Yet, if they were to build something without testing their design, something may be wrong with it. So as a result, you will spend more money manufacturing something with a defect than testing it with a prototype.

For question 5, I think it might be best if you answer that one. It is based on YOUR opinion and what YOU use. If you are asked about it, they will know it's from you and your opinion. Lol! But I hope I helped you out with the other questions! ;)

=======================================================

Explanation:

If 156 degrees is the interior angle measure, then 180-156 = 24 is the exterior angle measure.

Divide 360 over this to find that 360/24 = 15

This means the regular polygon has 15 sides.

I'm using the idea that if n is the number of sides, then 360/n is the exterior angle measure. So 180 - (360/n) is the interior measure.

Answer:

There is an error in the question.

All angles in an equilateral triange are 60º

Answer:

33.51 sq units

A=Θπr^2/360= 60 x pi x 8^2/360=33.51032164=33.51 sq units

Answer:y+3=1/4(x+4)

Step-by-step explanation:

First find the slope of the line with the points -1,1 and 0,-3

1-(-3)/-1-0 = -4

perpendicular is negative reciprocal which is 1/4

now we have the slope, and a point so we can put it in point slope form

y+3=1/4(x+4)

point slope form is y-y1 = m(x-x1)

with x1,y1 being the point and m being the slope
