Jacinto está cercando un terreno de forma rectangular. Cuando lleva puesto alambre a dos lados consecutivos de la tierra, se da cuenta que ha gastado 170 m de alambre. Si sabe que la diagonal del rectángulo mide 130 m, ¿cuáles son las dimensiones y el área del terreno?

Answers

Answer 1

Answer:

Step-by-step explanation:

Given the perimeter of the rectangular shape = 170m

Length of the diagonal = 130m

Perimeter = 2L + 2W

diagonal d² = L² + w²

L is the length of the terrain

w is the width

140 = 2L + 2W

70 = L+W ..... 1

130² = L²+w² ..... 2

from 1, L = 70-w

substitute into 2;

130² = (70-w)²+w²

130² = 4900-140w + 2w²

16900 = 4900-140w + 2w²

2w²-140w - 12000 = 0

w²-70w - 6000 = 0

On factorizing;

(w+50)(w−120) = 0

w - 120 = 0

w = 120 m

Since L = 70 - w

L = 70 - 120

L = -50m

Hence the dimension is 120m by 50 m

Step-by-step explanation:

8* x + y + y; use x=9, and y = 10​

Answers

The answer would be 134,217,748

Answer:

If we have 8 * x + y + y:

We have to first substitute in x and y where they should be:

=> 8 * 9 + 10 + 10

According to the order of operations(PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction, multiplication and division is you go from left to right order, and same with addition and subtraction.)), we do the multiplication first(8*9):

=> 72 + 10 + 10

Her work is correct and is shown below. (6x – 3) = (6x – 4) O The equation has infinite solutions. O The equation has one solution: x = 0. 4x - 2 = 3x - 2 O The equation has one solution: x = 4 O The equation has no solution.​

Answers

The true statement is that the equation has one solution; x = 0

How to determine the equation solution?

We have:

2/3(6x – 3) = 1/2(6x – 4)

When 2 is added to both sides, the equation becomes

4x = 3x

Subtract 3x from both sides of the equation

x = 0

Hence, the equation has one solution; x = 0

A computer store buys a computer system at cost of 572.40 cents the selling price was first at 9:54 but then the store was advised at 20% markdown on the system answer parts a and b

Answers

Answer: See explanation

Step-by-step explanation:

A. Find the current sale price. Round to the nearest cent if necessary.

B) Members of the stores loyalty club can and additional 10% off their computer purchases. How much do club members pay for the computer with their discount.

A. Current sales price will be:

= $954 - (0.2 × $954)

= $954 - $190.80

= $763.20

The teachers need to buy eggs and plastic spoons for the egg race event. The teachers want to have 1 egg for every spoon. The eggs are sold in packs of 6 , and the spoons are sold in packs of 10 . If the teachers want to buy exactly 30 spoons and have no leftovers, they need to buy

Answers

Answer:

5 packs of eggs

3 packs of spoons

Step-by-step explanation:

Eggs are sold in packs of 6

Spoons are sold in packs of 10

The teachers want to have 1 egg for every spoon

Find the Lowest common multiple of 6 and 10

6 = 12, 18, 24, 30, 36, 42, 48, 54, 60

10 = 20, 30, 40, 50, 60

The lowest common multiple of 6 and 10 is 30

If the teachers want to buy exactly 30 spoons and have no leftovers

Eggs are sold in packs of 6

Number of packs needed = 30 /6

= 5 packs

Spoons are sold in packs of 10

Number of packs needed = 30/10

= 3 packs

The teacher will buy 5 packs of eggs and 3 packs of spoons to have exactly 30 spoons and have no leftovers

Answers

Answer: -9/4

Step-by-step explanation:

First you subtract 7/2 from both sides of the equation

3x + 7/2 - 7/2= x - 1 - 7/2

Next what you do is simplify one you add 3 + 7/2 which is 9/2

Then you subtract X from both sides of the equation

3x - x = x - 9/2 - x

combine the terms

2x = -9/2

divide both sides of the equation by the same term

2x/2 = 9/2 / 2

cancel the terms and divide the numbers

x=-9/4

Solve 6.1−0.3≥c+1.
please help me

Answers

Answer:

c≤  24/25

Step-by-step explanation:

"0.3" was replaced by "(3/10)". 2 more similar replacement(s). Simplify 3/10

    61     3      

 (—— -  ——) -  (c + 1)  ≥ 0    then simplify 61/10

  10    10    

3.1       Adding fractions which have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

    61 - (3)                   29

————————  =  ——

     10                          5

29    

 —— -  (c + 1)  ≥ 0  

 5    

4.1   Subtracting a whole from a fraction

Rewrite the whole as a fraction using  5  as the denominator :

            c + 1     (c + 1) • 5

   c + 1 =  —————  =  ———————————

              1            5      

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Rewrite the whole as a fraction using  5  as the denominator :

                         c + 1     (c + 1) • 5

   c + 1 =  —————  =  ———————————

                             1            5    

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

                              29 - ((c+1) • 5)     24 - 5c

————————————————  =  ———————

                                          5                5

    24 - 5c

 ———————  ≥ 0  

      5    

 

Multiply both sides by  5  

5.2    Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

     5c-24  ≤ 0

5.3    Divide both sides by  5  

     c-(24/5)  ≤ 0

5.4      Add  24/5  to both sides

            c ≤ 24/5

Answer:

The ladder will go approximately 35.71 ft up the building.

Step-by-step explanation:

The 50 ft ladder is leaning against a building and the base of the ladder is 35 feet from the base of the building.

It means the ladder will form a right triangle with the building with the following dimensions:

base  =  35  f t hypotenuse  =  50  f t height = ?

Using the Pythagorean Theorem to determine the height,

[tex]a^2+b^2=c^2[/tex]

Here,

a is the heightb is the basec is the hypotenuse

Substitute the given values into the equation to determine the height:

[tex]a^2+b^2=c^2[/tex]

[tex]a^2+\left(35\right)^2=\left(50\right)^2[/tex]

[tex]a^2+1225=2500[/tex]

[tex]a^2=1275[/tex]

[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]

[tex]a=\sqrt{1275},\:a=-\sqrt{1275}[/tex]

[tex]a\:=\:35.71,\:\:\:a\:=\:-35.71[/tex]

We know that height can not be negative. Thus,

[tex]a=35.71[/tex] ft

Therefore, the ladder will go approximately 35.71 ft up the building.
