Answer:

240

Step-by-step explanation:

1. Area of two small triangles (OR one big) + Area of rectangle

2. Triangle

A(t) = 4*10 = 40 [4*10/2 + 4*10/2]

3. Rectangle

A(r) = 20*10 = 200

4. Combined Area

40+200=240

Step-by-step explanation:

So this figure has two parts:- A triangle and a rectangle

We can first solve area of Triangle

[tex] = \frac{1}{2} bh[/tex]

So the base is 20 and height is 4

[tex] \frac{1}{2} \times 20 \times 4 \\ = 10 \times 4 \\ = 40[/tex]

Now the area of rectangle

[tex] = l \times b[/tex]

Length is 20 and breadth is 10

[tex]l \times b \\ 20 \times 10 \\ = 200[/tex]

So the total area is 200 + 40 which is equal to 240

Answer:

80 rods of steel.

Step-by-step explanation:

Here is the complete question

A company makes steel rods shaped like cylinders. Each rod has a radius of 3 centimeters and a height of 20 centimeters. If the company used 45,781.2 cm³ of steel, how many rods did it make?

Solution

Since the steel rod is a cylinder whose volume, V = πr²h where r = radius of cylinder = 3 cm and h = height of cylinder = 20 cm.

We substitute these into V to find the volume of one rod.

So, V = πr²h

= π(3 cm)² × 20 cm

= π × 9 cm² × 20 cm

= 180π cm³

= 565.49 cm³

Since 45,781.2 cm³ of steel was used, this total volume of steel, V' equals the number of rods, n times the volume of one rod, V.

So, V' = nV

Making n subject of the formula, we have

n = V'/V

Substituting V' and V into the equation, we have

n = 45,781.2 cm³/565.49 cm³  

n = 80.96

We round n = 80.96 down to 80 since we cannot have a decimal number of rods.

So, n = 80 rods

So, the company made are 80 rods of steel.

Answer:

yep

Step-by-step explanation:

Using relations in a right triangle, it is found that the distance between Q and T is given by:

[tex]h = 32\sqrt{2}[/tex]

The relations in a right triangle are given as follows:

Researching the problem on the internet, it is found that:

Hence:

[tex]\sin{45^\circ} = \frac{32}{h}[/tex]

[tex]\frac{\sqrt{2}}{2} = \frac{32}{h}[/tex]

[tex]h = \frac{64}{\sqrt{2}} \times \frac{\sqrt{2}}{\sqrt{2}}[/tex]

[tex]h = 32\sqrt{2}[/tex]

A parabola graph is known to be a kind of graph that shoes a U-shaped curve that is often drawn for any given  quadratic function.

Note that in Mathematics, a parabola is said to be created as a result of the intersection of a right circular cone when passed by a plane surface and thus gives an symmetrical plane U-shaped curve.

Answer:

.133

Step-by-step explanation:

1 is in the tenths place

3 is in the hundredths place and

2 is in the thousandths place

when given at what place to be rounded to the answer should reflect the numbers to the thousandth place

so look to the right 5 or more add one to the left number

5 or less leave the number in the thousandths place as is

00000.1325

Step-by-step explanation:

Since rounding numbers dealso with real numbers or figures, .1325 will be represented as 0.1325 and it deals with numbers before the decimal which we also called significant numbers. those after are not significant.

So therefore in relation to this; 0.1325 the decimal will be moved three times to the left because thousands means there zeros. the result will be 0000.1325

Answer:

  (c)  9, 24, 26

Step-by-step explanation:

If you're familiar with Pythagorean triples, you may recognize that 10-24-26 is a doubling of the common 5-12-13 triple seen in many problems. That means the triple 9-24-26 cannot be a right triangle.

__

The "form factor" of f = a^2 +b^2 -c^2, where c is the longest side length, can signal the kind of triangle it is. f=0 indicates a right triangle (values satisfy the Pythagorean theorem). When there are a lot of numbers to try, I like to let a calculator or spreadsheet do the math. (See attached).

As indicated above, the 9-24-26 triple cannot be a right triangle. For f < 0, it will be an obtuse triangle.

113.04 in

Step-by-step explanation:

Area of a circle = Tr²

Circumference of a circle = 2Tr

T = 3.14

r = radius

The radius has to be determined to calculate the area of the circle

43.96 in = 2  x r x 3.14

r = 43.96 in / 2  x 3.14

= 7 in

Area = 3.14 x 7² = 153.86 in = 154 in²

Answer:

Al hijo mayor le corresonden 0,18 Hm²

Al segundo hijo  le corresponden 1200 m²

Al hijo menor le corresonden   6000000 cm²

Step-by-step explanation:

Al hijo mayor le corresponden 18 Dm²  la mitad de la finca

En Hm²     sn 18 /100   0,18 Hm²

Al hijo menor le corresponden 1/3 de la mitad de la finca (18 Dm²)

es decir  1/3 * 18 Dm²      6  Dm²    

en m²    serán      6 * 100 = 600 M²

y en cm²      600 * 10000 = 6000000 cm²

Al segundo hijo le corresponden 2/3 de la mitad es decir
