On monday maggie ran n miles, on tuesday she ran 90% of the number of miles that she ran on monday. on wednesday she ran 50% of
Andrew [12]

Step-by-step explanation:

On Monday maggie ran n miles.

On Tuesday, she she ran 90% of the number of miles that she ran on Monday i.e \dfrac{90}{100}\times n=0.9n.

On Wednesday, she ran 50% of the number of miles that she ran on Tuesday i.e. \dfrac{50}{100}\times 0.9n=0.45n

First expression : n+0.9n = 1.9 n

Second expression : n + 0.9 n + 0.45 n = 2.35 n

Hence, this is the required solution.

1<br> Which sequence of transformations takes AA to its image, AB ?
lianna [129]

A rigid transformation preserves the dimensions of the image

The option that gives the sequence of transformation that takes ΔB to ΔB is  the option B.

<u>(B) Reflection across y-axis and a translation 2 units down </u>

Reason:

Question: The sequence of transformation that takes ΔA to image ΔB

<em>From a similar question, we have, ;</em>

<em>The vertices of triangle ΔA are; (-8, 9), (-9, 4), (-3, 4)</em>

<em>The vertices of triangle ΔB are; (8, 7), (3, 2), (9, 2)</em>

<em>The options are; </em>

<em>(A) Reflection over the x-axis and 2 units translation down</em>

<em>(B) Reflection over the y-axis and 2 units translation down</em>

<em>(C) 90° rotation after a translation of 2 units down</em>

<em>(D) 90° rotation after a translation of 12units right</em>

Solution;

The length of the base of ΔA = -3 - (-9) = 6

The length of the base of ΔB = 9 - 3 = 6

Therefore, the length s of triangle A and triangle B are equal

The orientation of the base of ΔA and ΔB are both horizontal

The location of the the side that traverses four cells are both furthest from the y-axis, or the vertical

Therefore, ΔB is a reflection of ΔA across the y-axis

We also have;

The base of ΔB is 2 units lower than the base ΔA

Therefore, the correct option is option B, reflection across y-axis and a translation 2 units down
