Answer:742 cm^3

Step-by-step explanation:

Height=h=12cm

Radius=r=5cm

π=3.14

volume of cylinder=π x r^2 x h

Volume of cylinder=π x r x r x h

Volume of cylinder=3.14 x 5 x 5 x 12

Volume of cylinder=742 cm^3

Answer:

0.5 feet left

Step-by-step explanation:

12 inches = 1 foot

36 inches = ? feet

36 × 1 = 36

12 × ? = 12?

36 = 12?

? = 36/12

? = 3 feet

18 inches = x feet

18/12 = 1.5 feet

3 + 1.5 = 4.5 feet total used

5(total) - 4.5(feet used) = 0.5 feet left

Answer:

y = (-1/2)x + 9/2

Step-by-step explanation:

the equation of a straight line can be written as;

y = mx + c ......1

Where;

m = slope

c = intercept

For two lines to be perpendicular their slope must be opposite reciprocal of each other.

m1 × m2 = -1 .....2

Given;

The equation Contains (3, 3); and perpendicular to the line y = 2x - 1

Slope of the given equation m1 = 2

Slope of the line m2; substituting m1 to equation 2.

2 × m2 = -1

m2 = -1/2

So,

y = (-1/2)x + c

To solve for c, let's substitute the given point on the line; (3,3).

3 = (-1/2)(3) + c

3 = -3/2 + c

c = 3 + 3/2

c = 9/2

Therefore, the equation of the line that has the given properties is;

y = (-1/2)x + 9/2

Answer: A 15/100

Step-by-step explanation:

1. Convert 17/20 into percents

2. You get 85% Which is how much of her homework she has completed

3. To find what she has left subtract 85 from 100

4. You get 15 or 15/100 or 15% more of the test she hasn’t completed and needs to complete

Firstly we need to find m<DNY

m<DNY=(60+90)÷2=75

N9w we can find m<KNY

m<KNY+m<DNY=180°(Because these are adjacent corners)

m<KNY+75°=180°

m<KNY=180°-75°

m<KNY=105°

Answer:

-5/2

Step-by-step explanation:

In order to find the slope of a perpendicular line: negate the reciprocal of the original slope

Answer:

The area of shaded region is 25.5 units³

Step-by-step explanation:

Step 1 , you have to find the area of rectangle and triangle using the formulas :

Rectangle :

[tex]area = length \times width[/tex]

Let length = 5 units,

Let width = 6 units,

[tex]area = 5 \times 6[/tex]

[tex]area = 30 \: \: {units}^{2} [/tex]

Triangle :

[tex]area = \frac{1}{2} \times base \times height[/tex]

Let base = 3 units,

Let height = 3 units,

[tex]area = \frac{1}{2} \times 3 \times 3[/tex]

[tex]area = \frac{1}{2} \times 9[/tex]

[tex]area = 4.5 \: \: \: {units}^{2} [/tex]

Step 2 , in order to find the shaded region, you have to substract the area of triangle from the area of rectangle (As the triangle is not shaded) :

[tex]area = 30 - 4.5[/tex]

[tex]area = 25.5 \: \: \: {units}^{2} [/tex]

Answer:

C. (5x + 6) (5x - 6)

Step-by-step explanation:

25 is a perfect square, meaning its two factors are identical (5), and 36 is also a perfect square with two identical factors (6). With this information, we can split the expression below like this:

[tex]25x^2 - 36\\(5x ) (5x )[/tex]

Since 36 is negative, we have to have a positive 6 and a negative 6:

(5x - 6) (5x + 6)

Answer:

y= -5

is the solution of the system of equations

Answer:

D. 96

F. 32

Step-by-step explanation:

The inequality 3x ≥ 96, means that x and 3 must be multiplied to get a product that is greater than 96.  So to figure this out, you must plug in the numbers given for x, like so:

3x ≥ 96

A. 3(31) ≥ 96

     93 ≥ 96                            This is incorrect since 93 is not greater than 96

A tip that makes this easier is that, you can see that 31 multiplied by 3 is 93, which is only a couple numbers off 96, so all numbers after 31 will result in a product greater than 96. For example:

D. 3(96) ≥ 96

    288 ≥ 96                             This inequality is correct

F. 3(32) ≥ 96

   96 ≥ 96                        

The inequality sign states that the number must be either greater or equal to 96, which it is.

Answer:

Acute and equilateral triangle

Step-by-step explanation:

An acute triangle is a triangle in which each of its angles measures less than 90 degrees.

There are three types of acute e triangle

1. Equilateral triangle: This is an acute triangle which has all of its sides equal as in the case of Steve.

2. Isosceles triangle is an acute triangle that has only two equal sides.

3. Scalene triangle is an acute triangle that has no Equal sides, that is, none of its sides are equal.

Answer:

Equilateral triangle

Step-by-step explanation:

Steve's triangle is an acute triangle.

An acute triangle has each of its 3 acute. That is the angles are less than 90°. It could be an equilateral triangle, isosceles or scalene triangle.

In this case, it is an equilateral triangle since all 3 sides (5m) are equal. Therefore all 3 angles of the triangles are equal( angle would be 60°).

Answer:4.6

Step-by-step explanation:

Percentage decrease=(65-62)/65 x 100

Percentage decrease=3/65 x 100

Percentage decrease=(3x100)/65

Percentage decrease=300/65

percentage decrease=4.6

Answer:

S(a) = 27,5036  squared units

Step-by-step explanation:

Shaded area is :

S(a)  =  Area of the circle  - area of the regular pentagon      (1)

A(c) = area of the circle

A(c) = π*(r)²    ⇒  A(c) =  π*(6)²     ⇒   A(c) =  36*π   ⇒ A(c) = 113,0976 squared units

Area of a regular pentagon:

a) If we draw a straight line between the center and each vertex we get  5 triangles, and if we draw the apothem for each side, we get 10 triangles. We will calculate the area of one  of these triangles

The first 5 triangles has a central angle equal to 72⁰ according to:

360/5  =  72

When we divide these triangles in two triangles by means of the apothem, each central angle will be of 36⁰, then

sin 36⁰  =  0,58778  and cos 36⁰ = 0,809017    and   sin 36⁰ =  x/6      here x is half of the side of the regular pentagon. Then

0,58778  =  x/6

x = 6*0,58778

x =  3,52668 units of length  

and cos 36⁰ = a/6      where a is the apothem, then

0,809017  = a / 6     ⇒   a  = 6*0,809017

a =  4,8541 units of length

Now we are in conditon to calculate area of the triangles as:

A(t) = (1/2)*b*h

A(t) = (1/2)*x*a     ⇒ A(t) = 0,5* 3,52668*4,8541

A(t) = 8,5594 squared units

Finally we have 10 of these triangles, then

Area of regular pentagon is : 10*A(t) squared units

A(p) = 85,594 squared units

Now plugging these values in equation (1) we get the shaded area

S(a) =  113,0976 - 85,594

S(a) = 27,5036  squared units
