You first divide 40 by 19:

19/40=?

Then you convert that to percentage by dropping the decimal point and attaching a %

(hint: you should get 48% about :)

Answer:

47.5%  is 19 of the 40 .

Step-by-step explanation:

As given

19 is a part value of 40.

Let us assume that the x % is 19 of the number 40.

Now written x % in the decimal form.

= \frac{x}{100}

Than the equation becomes

\frac{x\times 40}{100} = 19

Solving the above

\frac{19\times 100}{40} = x

\frac{1900}{40} = x

x = 47.5%

Therefore  47.5%  is 19 of the 40 .

Find the lateral area of the regular prism with height h, if the base of the prism is: Equilateral triangle with the side 4 cm a
Shtirlitz [24]

Equilateral triangle with the side 4 cm and h=2.5 cm

In equilateral triangle all sides are equal

so all sides are equal in the base of the prism

lateral area of the prism = Perimeter of the base * height

Perimeter of the base equilateral triangle = side + side + side

lateral area of the prism =(side + side + side) * height

= (4+4+4) * 2.5

= 30 cm^2

lateral area of the prism = 30 cm^2

Find the area of the irregular shape. Round to the nearest tenth.
svp [43]
Given: 
Irregular Shape: 
Semi-circle and rectangle:

Area of a rectangle = l * w
Area of a semi-circle = (π r²)/2

Area of rectangle = 8 cm * 5 cm = 40cm²
Area of a semi-circle = (3.14 (4²))/2 = (3.14*16)/2 = 50.24/2 = 25.12cm²
4² is taken from diameter of 8cm divided by 2 to get the radius.

Total area = 40 cm² + 25.12 cm² = 65.12 cm²

The measure of one angle of an octagon is two times smaller that of the other seven angles. What is the measure of each angle?
Anestetic [448]

Answer:

7 of the angles measure 144 degrees each and one angle measures 72 degrees

Step-by-step explanation:

Let

x -----> represent the measures of the seven same-size angles,

x/2 ----> represent the measure of the one that is "two times smaller."

we know that

The sum of internal angles of a polygon can be calculated as:

S=180^o(n-2)

where

n is the number of sides of the polygon

In this case

n=8 (octagon)

substitute

S=180^o(8-2)=1,080^o

so

The linear equation that represent this problem is

\frac{x}{2}+7x=1,080

solve for x

\frac{15x}{2}=1,080\\\\15x=2,160\\\\x=144^o

so

\frac{x}{2}=72^o

therefore

7 of the angles measure 144 degrees each and one angle measures 72 degrees
