The length of the diagonal is

, which is 111.80 yards.

The possible dimensions of the sports field are width 70 yards, length 7-3x yards.

Dimensions in mathematics are the measure of the size or distance of an object or region or space in one direction.

Given that, the width is at least 50 yards and area is (490-210x)

We can conclude the shape of the sports field is rectangular.

We need to find the Greatest Common factor between 490 and 210, this way:

490 = 2 × 5 × 7 × 7

210 = 2 × 5 × 3 × 7

Then the greatest common factor is 2 × 5 × 7 = 70

This GCF is also equal to 70 yards (given in option), therefore it's one of the dimensions of the sports field.

Now, we calculate the other side of the sports, this way:

Second dimension of the sports field = (490-210x)/70

= 7-3x

Hence, The possible dimensions of the sports field are width 70 yards, length 7-3x yards.

Answer:

(75+88+92+94+71+x)/6=85 x 1,21

Step-by-step explanation:

Answer:

x=12

Step-by-step explanation:

Before starting this question, you need to know that the total degree of any given triangle is 180 degrees.

Now looking at the question, we know one side is 90 degree since it is a right triangle.

180-90=90

This let us know that the remaining two angles will have to add up to equal to 90 degrees.

2x+1+5x+5=90

First, combine like terms.

7x+6=90

Now we have to get x by itself, subtract 6 on both sides then divide by 7.

7x=84

x=12

Answer:

Step-by-step explanation:

First you need to calculate the entire length (in meters) of the metal used in the gate, then multiple the length by 2.5 kg per meter

Break it into parts.......

four pieces on along the outside is just the perimeter of a rectangle

         P = 2( L + H)        both sides and the top and bottom

the two crossing metal pieces are just the hypotenuse of a right triangle and since we have two pieces of metal

        a² + b² = c²     or   L² + H² = Hyp²          solving for the htpotenuse

                         Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]              

so the total length of the gate metal is

P = 2( L + H)    plus        2 Hyp = [tex]\sqrt[]{L^2 + H^2}[/tex]  

   = 2( 12 + 5)      +     2 [ √(12² + 5²) ]

   =       34          +   2 [ √( 144 + 25) ]

   =       34  +  2 ( √169)

   =       34 +  2( 13)

   =       34 + 26

   =     60 meters   of gate metal            metal weighs  2.5 kg per meter

  Total weight equals 60 meters   times    2.5 kg per meter

    Total weight = 60 (2.5)    =     150 kg

7/20

Step-by-step explanation:

Answer:7/10

Step-by-step explanation:

Here is the way that I think is the simplest method of changing a percentage a fraction. This percentage has two digits in it, so put it over a 1 and two zeros and then simplify. 35/100 is simplified to 7/20.

Step-by-step explanation:

Answer:

v = 165

Step-by-step explanation:

v/22 -0.1 = 7.4

v/22 = 7.4+0.1 =7.5

v = 7.5*22

v = 165

Answer:

[tex]v = 165[/tex]

1) Add 0.1 to both sides.

[tex] \frac{v}{22} = 7.4 + 0.1[/tex]

2) Simplify 7.4 + 0.1 to 7.5.

[tex] \frac{v}{22} = 7.5[/tex]

3) Multiply both sides by 22.

[tex]v = 7.5 \times 22[/tex]

4) Simplify 7.4 × 22 to 165.

[tex]v = 165[/tex]

Therefor, the answer is v = 165.

Step-by-step explanation:

Wrapping paper goes around the box, rather than filling the content of the box. So SA is what we are looking for

2(13x5 + 13x8 + 5x8) = 418 > 400

So 400 does not suffice, you would need 18 more

Here, Distance covered by Lucas on Saturday

= 4x – 5 miles

Now, Distance covered by Lucas on Sunday

= 3x – 10 miles

________________________________

Hence, Difference between the distances

would be / –

Distance covered on Saturday – Distance covered on Sunday

= (4x – 5) – (3x – 10)

= 4x – 5 – 3x + 10

[ Because (– * + = – ) And ( – * – = +) ]

= 4x – 3x + 10 – 5

= 1x – 5

= x – 5 ( – Ans )

Hence, The difference between Distance covered ( In miles ) is ( x – 5 ) .

Answer:

c

Step-by-step explanation:

Answer:

x=2

Step-by-step explanation:

first we will distribute out everything

-2x +5 +4x+ 9 = 3(6 +4x)- 12x

(multiply 3 to both 6 and 4x)  

-2x +5 +4x+ 9= 18 +12x -12x

then combine like variables on both sides

(add -2x and 4x and add 5 and 9, for the other side add 12x and -12x)

2x+14= 18  

then isolate x

2x=4

x=2

and substitute x for 2 to double check

-2(2)+5+4(2)+9=3(6+4(2))-12(2)

18=18

therefore 2 is correct

Answer:

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

Step-by-step explanation:

x² + y² -2x - 10y + 17 = 0

Find the center and radius of this circle

We have the equation

x² + y² -2x - 10y + 17 = 0

We collect like terms

x² - 2x + y² - 10y = -17

x² - 2x + (-2/2)² + y² - 10y + (-10/2)² = -17 + (-2/2)² + (-10/2)²

The center of the circle is point: C=(1,5).

The radius of the circle is r=3.

Answer:

d) 10

Step-by-step explanation:

x ÷ [tex]\frac{1}{2}[/tex]  + 8 = 13

substitute 10 for x:

⇒ 10 ÷ [tex]\frac{1}{2}[/tex]  + 8 = 13

solve:

1) divide 10 by [tex]\frac{1}{2}[/tex]

⇒ 10 ÷ [tex]\frac{1}{2}[/tex]  = 5

2) add 8 to 5

⇒ 8 + 5 = 13

Answer:

150 boys

Step-by-step explanation:

equation:

⇒ 5x + 4x = 270

add like terms:

⇒ 9x = 270

divide 9 on both sides:

⇒ [tex]\frac{9x}{9} = \frac{270}{9}[/tex]

solve:

⇒ x = 30

take original equation and subtitute 30 for x;

⇒5 x 30 + 4 x 30 = 270

⇒ 150 + 120 = 270

We can see that if there were 270 students, 150 would be boys and 120 would be girls.
