Answer:

I think its 28.

Step-by-step explanation: Dont take my word for this tho

the ratio is 1:2 and that would mean that whatever length DA, HE is 2 times.

The length of BC is 14 so 14 x 2 is 28.

The length, in meters, of side FG on the photocopied image is 28 m and this can be determined by using the concept of dilation.

Given :

The following steps can be used in order to determine the length, in meters, of side FG on the photocopied image:

Step 1 - According to the given data, the side length of DA is 2 times the side length of HE.

Step 2 - From the above step, it can be concluded that 2 is the dilation factor.

Step 3 - From the given data, the length of BC is 14m. So, the length of the side FG is given by:

FG = 2 BC

Step 4 - Substitute the value of length of side BC in the above expression.

FG = 2(14)

FG = 28 m

Therefore, the correct option is C).

So, the prime factors of 100 are written as 2 x 2 × 5 x 5 or 22 x 52, where 2 and 5 are the prime numbers. It is possible to find the exact number of factors of a number 100 with the help of prime factorisation. The prime factor of the 100 is 22 x 52. The exponents in the prime factorisation are 2 and 2.

Step-by-step explanation:

Answer:

The prime factorization of 100 is 2 * 2 * 5 * 5. Using exponents, this number can also be written as 2^2 * 5^2.

Equation: $5.5+$12.75

Step-by-step explanation:

Answer: At the Month May Jordan as able to get enough money to buy the phone.

Work:

December:$5

January:$10

February:$20

March:$40

April:$80

May:$160 <--Answer

____________________________________________________________In the problem Jordan saves $5 at December, then at January Jordan saved $10 which is twice as December's saved money amount. February, Jordan saved $20, which is twice as January's saved money amount. March is $40, which is twice as February's saved money amount. For April it is $80, which is twice as March's money amount, May is $160 which is twice as April's money amount. Or another way to say this is by starting at $5. Then, keep multiplying by 2 for each month until you get $150 or more. When you do, stop at the month that gets you $150 or more. When i did this exact method, I got $160 on the Month of May. $160 is more than enough for Jordan to buy his phone. So the month May is the correct answer where Jordan can get enough money for his phone.

Answer: The fifth month; By April Jordan would have saved more than enough to buy a new phone.

Step-by-step explanation:

Dec $5

Jan $10

Feb $20

Mar $40

Apr $80

Dec + Jan = $15($5+$10)

Dec+ Jan + feb = $35($5+$10+$20=$35)

Dec+ Jan + feb + mar = $75 ($5+$10+$20+$40=$75)

Dec+ Jan + feb + mar + apr = $155

($5+$10+$20+$40+$80=$155)

Answer:

The answer is D x ≤ 1

Step-by-step explanation:

The angle at D which is m∠ADB is calculated to be  180 - ( α + β ) / 2

Given data

< A = α

∠ B = β

Angle bisectors divides the given angle into two and form a triangle which is ∆ADB

The angles that form ∆ADB are as follows

< A =  α / 2

∠ B = β / 2

to find < D we use sum of angles in a triangle which is 180 degrees and solve as follows

< A + < B + < D = 180 degrees

where < D = m∠ADB, substituting the other values gives

α / 2 + β / 2 +  < D  = 180

( α + β ) / 2  +  < D  = 180

< D  = 180 - ( α + β ) / 2

Since < D = m∠ADB .We can therefore say that m∠ADB =  180 - ( α + β ) / 2

Answer:

Y=13

Step-by-step explanation:

X is 45 so

45+5y+5=9y-2 solve and y=13

Answer:

y = 13

Step-by-step explanation:

x  + 135 = 180                   {linear pair}

         x = 180 - 135

          x = 45

 9y - 2 = 5y + 5 + x    {Exterior angle property of triangle}

 9y - 2 = 5y + 5 + 45

9y - 2 = 5y + 50       {Subtract 5y from both sides}

9y -5y  -2 = 50

  4y - 2 = 50              {Add 2 to both sides}

         4y = 50 + 2

         4y = 52             {Divide both sides by 4}

            y = 52/4

      y = 13

Quadrilaterals are shapes that have four sides; these four sides may or may not be:

Check below on how to determine the probability

From the question, we have the following parameters:

The probability that the quadrilateral has four equal side lengths, given that the quadrilateral has four right angles is calculated using:

P(E | R) = n(E and R)/n(R)

This gives

P(E | R) = 2/8

Express as percentage

P(E | R) = 25%
