Leo necesita 4 de metros azul y 3 de tela roja para hacer un proyecto. 5 7 ¿aproximadamente cuanta tela necesita?

Answer:

x=1/9

Mark me as brainliestttt

Answer:

x = 3

Step-by-step explanation:

To solve this equation you use the pythagorean theorem to find the missing side length.

4^2+x^2=5^2

16+x^2=25

Then subtract 16 from both sides

x^2=9

Then just find the square root of 9 which is 3

Answer:

35° is ur answer

Step-by-step explanation:

Answer:

A= 150°

B=30°

C=150°

Step-by-step explanation:

Since a line is 180°, you can write an equation for C. C+30°=180° , from here use algebra to find C. The value of C will be 150°. When the value of C is 150° , since they're supplementary angles, the value of A will also be 150°.

Important thing to note:

The value of all these angles combined together is 360°.

Answer:

Proved below

Step-by-step explanation:

Question 2.2.3 says we should prove that;

√18 - √128 + 2^(2.5) = -√2

Breaking this down gives;

√(9 × 2) - √(64 × 2) + 2^(5/2)

This gives;

>> 3√2 - 8√2 + (2^(5))^(½)

>> 3√2 - 8√2 + √32

>> 3√2 - 8√2 + √(16 × 2)

>> 3√2 - 8√2 + 4√2

>> (3 - 8 + 4)√2

>> -√2

This is equal to the right hand side and so it is proved.

Answer:

7/6

Step-by-step explanation:

So first you want to find the common denominator. Which would be 6. Then you want to multiply 3x3 and 1x2. So it would now be, 9/6-2/6=7/6

Step-by-step explanation:

6p² - 13p + 6

= 6p² - ( 9 + 4 )p + 6

= 6p² - 9p - 4p + 6

= 3p ( 2p - 3 ) - 2 ( 2p - 3 )

= ( 2p - 3 ) ( 3p - 2 )

Hope it helps :)

Step by step:

6p2 - 13p + 6

6p2 - 4p - 9p

Common factor from the two pairs

6p2 - 4p - 9p + 6

2p(3p-2) - 3 (3p - 2)

Then, rewrite in factored form

2p(3p - 2) - 3 (3p - 2)

(2p - 3) ( 3p - 2)

Solution

(2p - 3)(3p - 2)

Answer:

D. about 7.3 units

Step-by-step explanation:

Answer:

Since the long side is 7 units and the shorter side is 2 units, to find the hypotenuse it would be 7^2+2^2=Hypotenuse^2-->49+4=Hypotenuse^2--> [tex]\sqrt{53} \\[/tex]=Hypotenuse-->7.280109889 which is about 7.3 :)

Answer:

Biggest number = 13

Smallest number = 12

Step-by-step explanation:

x + y = 25... eqn 1

x - y = 1.... eqn 2

subtract equation 2 from 1

x + y = 25

-x - y = 1

---------------

2y = 24

divide both sides by 2

y = 24/2

y = 12

substitute y=12 into equation 2

x - 12 = 1

x = 12+1

x = 13

Step-by-step explanation: Volume

this should help if not let me know..

Let’s revisit our friend Wally from “Area and Perimeter” and use another aspect of his yard to introduce the concept of volume. Wally is a swimmer and wants to install a lap pool in his backyard. Because he has some extra space, he is going to build a pool that is 25 yards long, 2 yards wide, and 2 yards deep. How many cubic yards of water must be used to fill the pool (assuming right to the top).

Much as we did with area (counting unit squares), with volume we will be counting unit cubes. What is the volume of a unit cube? Let’s look at figure 1:

FINDING THE VOLUME OF A CUBE

Figure 1.

Figure 1. Volume = 1 yd × 1yd × yd = 1 cubic yard

The shape at left is a cube (all sides are equal length). In particular, because all sides are of length 1, this cube is called a unit cube.

We know the area of the base from our previous work (1 yd × 1 yd or 1 square yard). We are going to take that area and extend it vertically through a height of 1 yard so our volume becomes

Volume = 1 yd × 1yd × yd = 1 cubic yard

How does this help Wally? Well, if he can count the number of unit cubes in his pool, he can determine the volume of water needed to fill the pool.

GUIDED EXAMPLE

Filling Wally’s Pool

Figure 2. Volume = Length× Width × Height or V = LWH

Figure 2. Volume = Length × Width × Height or V = LWH

If we fill the pool with unit cubes, we can fill 25 unit cubes along the length, 2 along the width and 2 along the height. That would give us 25 × 2 × 2 = 100 unit cubes or:

Volume = 25 yd × 2 yd × 2 yd = 100 cubic yd

Explicit formulas for the types of rectangular solids used in the previous section are as follows:

NOTES ON VOLUME

Volume is a three-dimensional measurement that represents the amount of space inside a closed three-dimensional shape.

To find volume, count the number of unit cubes inside a given shape.

If there are units, include units in your final result. Units will always be three-dimensional (i.e. cubic feet, cubic yards, cubic miles, etc…)

Find the volume of each shape below.

Volume of A Circular Cylinder

Figure 3.

Figure 3.

Can we use what we know about the area of a circle to formulate the volume of a can (also called a cylinder)? Take a look at figure 3.

The base circle is shaded. If we take the area of that circle (A = A = πr2) and extend it up through the height h, then our volume for the can would be:

V = πr2h.

Find the volume of the cylinder shown below.

Angles

Angles, often measured in degrees, measure the amount of rotation or “arc” between intersecting line segments. We need to have some sense of what an angle is before moving on to the next topic. See some examples and terminology below.

Fig2_4_9  

This angle measures 30º

This angle measure is less than 90º

Angles less than 90º are called acute angles

Fig2_4_10  

This angle measures 90º

Angles that measure exactly 90º are called right angles

The small box in the angle corner denotes a right angle

Fig2_4_11  

This angle measures 120º

This angle measure is more than 90º

Angles that measure more than 90º but less 180º than are called obtuse angles

Fig2_4_12  

This angle measures 180º

Angles that measure exactly 180º are called straight angles
