A rental company charges costumers a 14.75 fee plus $0.15 per smile to rent a moving van after returning the moving van a custom

kumpel [21]

Step-by-step explanation:

I guess, the question is, how many miles were driven ?

if that is the case, then

we need to deduct the basic fee of $14.75, as this would have been paid, even if they did not drive a single mile.

so, 50.45 - 14.75 = $35.70

that is the actual cost for the driven miles.

how many miles ?

well, how often do $0.15 fit into $35.70 ?

35.7 / 0.15 = 238 miles.

this customer had been driving the moving van for 238 miles.

If (3a-5b) : (3a+5b)=1:4 then find the value of a:b

rodikova [14]

Answer:

a : b = 25 : 9

Step-by-step explanation:

(3a - 5b) : (3a + 5b) = 1 : 4

Product of extremes = product of means

(3a - 5b) *4 = (3a +5b) * 1 {Distributive property}

3a * 4 - 5b*4 = 3a + 5b

12a - 20b = 3a + 5b

Add 20b to both sides

12a = 3a + 5b + 20b

12a = 3a + 25b

Subtract 3a from both sides

12a - 3a = 25b

9a = 25b

$\dfrac{a}{b}=\dfrac{25}{9}$

a:b = 25 : 9

Draw and label the final image of △ABC after the given sequence of transformations. Reflect △ABC over the y−axis and then transl

arlik [135]

Answer: The correct option is A.

Explanation:

From the given figure it is noticed that each box in the graph represents the length of 2 units. The coordinates of point A,B and C are (-1,1),(-3,3) and (-2,4) respectively.

If a point reflects over the y-axis then,

$(x,y)\rightarrow(-x,y)$

So after reflecting coordinates of point C become,

$(-2,4)\rightarrow(2,4)$

If a point translated by (a,b), then

$(x,y)\rightarrow(x+a,y+b)$

So, after reflection over y-axis followed by translation by (2,-2), the coordinate of C are,

$(2,4)\rightarrow(2+2,4-2)\\(2,4)\rightarrow(4,2)$

Similarly the image of point A and B are (3,-1) and (5,1) respectively.

The image of C after reflection over y-axis followed by translation by (2,-2) is (4,2), which is shown in only graph A, Therefore A is the correct option.
