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.

Answer:

D

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

Answer:

x=18

Step-by-step explanation:

Hey There!

So if you did not know all of the angles in a triangle will add up to equal 180

So we use the equation

180=2x+3x+5x

and solve for x

step 1 combine like terms

2x+3x=5x

5x+5x=10x

so now we have

180=10x

step 2 divide each side by 10

180/10=18

therefore x = 18

hope this helps and if you have any more questions feel free to ask :)

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:

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:

If a quadrilateral has four congruent sides and four right angles, then it's a square (reverse of the square definition). If two consecutive sides of a rectangle are congruent, then it's a square (neither the reverse of the definition nor the converse of a property)

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:

I need points, sorry, i cant help

Step-by-step explanation:

Answer:

Step-by-step explanation:

If we assume that the angle at A is 90 degrees.. which it does seem like it would be.  then use that the sum of the angles around the inside of a right triagle is 180 .   so  you have

180 = 37 + 90 + x

53° = x

Answer:

Step-by-step explanation:

place a point at (0,0)- the starting point

next point at (2,1) - in 2 minutes she is 1 block away

Next point (4,2)- in 4 minutes she will be 2 blocks away

Connect those 3 points

then place a point at (9, 2)- 5 minutes later she was still at the store

Connect points

Point at (11,1) and (12,0) and connect

Answer:

probably 4 or 2? i mean they are smaller than 8 afterall

Step-by-step explanation:

The two numbers that could be x in x < 8 are 1 and 2 or 1 and 4.

Word problems with algebraic expression as the name implies include technical words used together with variables of an algebraic term.

From the given question;

We are to determine two numbers that could be x and which must be less than 8 as seen in the expression below;

The first thing to do is to look for the factors of 8 which are:

From there, the two numbers that could be x which are less than 8 are:

This is because the multiplication of those two numbers is still less than 8.

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

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.

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 ) .
