Answer:

Jason likely misplaced the decimal, because 3x1 = 3, and if the decimal was between the 2 and the 5, the number would be near 3.

Step-by-step explanation:

(3.4 / 4) × 3 = 2.55

Line L is mapped onto the line t by a dilation centered at
STatiana [176]

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size

  • If the equation of a  line is ax + by = k is dilated, with center origin and scale factor k, then the equation of the image of the line is kax + kby = kc
  • The line and its image are parallel
  • The coordinates of a general point on the image is (kx , ky)

Line L is mapped onto the line T by a dilation centered at the origin and  a scale factor of 3.

That means lint T is the image of line L after dilation

∵ The equation of line L is 2x - y = 7

∵ Line L is dilated by scale factor 3 and centered at origin

- That means multiply the equation of line L by 3 to find the

   equation of line t

∵ Line T is the image of line L after dilation

∴ The equation of line T is (3)(2x) - (3)(y) = (3)(7)

∴ The equation of line T is 6x - 3y = 21

<em>Very important note:</em>

The equation of line T is the same with equation of line L but multiplied by the scale factor 3 ⇒ L and T are coincide lines (same line)

That means the equation of lines T and L is 2x - y = 7

The equation of line T is 2x - y = 7 ⇒ (6x - 3y = 21)

A bat and a ball cost one dollar and ten cents in total. The bat costs a dollar more than the ball. How much does the ball cost?
antoniya [11.8K]
10 cents, cause the {ball +$1.00=$1.10} subtract $1 from both sides the ball=$0.10

What is the formed of the fact family for 6,7,13 what is the answer​
Keith_Richards [23]

Answer:

7 + 6 = 13

13 = 7 + 6

13 – 6 = 7

7 = 13 – 6

Step-by-step explanation:

7 + 13 = 20

13 + 7 = 20

13 – 13 = 0

13 – 0 = 13

7 + 0 = 7

6 + 0 = 6

13 – 0 = 13

13 – 13 = 0

7 + 0 = 7

6 + 0 = 6

13 – 0 = 13

13 – 13 = 0

7 + 6 = 13

13 = 7 + 6

13 – 6 = 7

7 = 13 – 6

If the figure is rotated 270° counterclockwise about the origin, what is the length of segment N′P′?
kap26 [50]

Answer:

Option (2)

Step-by-step explanation:

Since, rotation of any figure is a rigid transformation, side lengths and measure of angles of the image polygon after rotation will remain same.

NP = N'P'

Coordinates of N → (5, 9)

Coordinates of P → (7, 9)

Formula of distance between two points (x_1,y_1) and (x_2,y_2) is,

d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

By this formula length of NP = \sqrt{(7-5)^2+(9-9)^2}

                                               = 2 units

Therefore, Option (2) will be the correct option.
