△FOD~△HOG. Identify the coordinates of D and the scale factor. HELP PLEASE!!

cupoosta [38]

Answer:

Option D. $(0,-20/3)$ , $\frac{2}{3}$

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal

$\frac{OH}{OF}=\frac{OG}{OD}$

substitute values and solve for OD

$\frac{6}{4}=\frac{10}{OD}$

$OD=10*4/6=20/3$

therefore

the coordinate of point D is $(0,-20/3)$

the scale factor is equal to $\frac{OF}{OH}=\frac{4}{6}=\frac{2}{3}$

What is the median please help please help

Paladinen [302]

Answer:

54.5

Step-by-step explanation:

To find the median, first we have to put the numbers in ascending/increasing order.

43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set

36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.

The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.

36, 43, 50, 50, 51, 58, 59, 60, 69, 73

51 + 58 = 109

109/2 = 54.5

A first number plus twice a second number is 13 Twice the first number plus the second totals 35 Find the numbers.

Sophie [7]

Answer: the first number is 19 and second number is -3

Step-by-step explanation:

Let the First number be represented as x

and second number be represented as y

Therefore, A first number plus twice a second number is 13 be expressed as

x + 2y = 13-----equation 1

also Twice the first number plus the second totals 35

2x+ y = 35---- equaton 2

Step 2 --- Solving

x + 2y = 13-----equation 1

2x+ y = 35---- equation 2

By substitution, making x subject of formulae in equation 1

x+ 2y = 13

x= 13 - 2y

putting the value of x= 13- 2y in equation 2

2( 13 - 2y) + y= 35

26 - 4y + y= 35

-4y + y= 35- 26

-3y= 9

y = 9/-3

y= -3

To Find x , using equation 1

x + 2y = 13

x+ 2 x -3= 13

x-6=13

x= 13+6

x= 19

Therefore the first number = 19 and the second number = -3
