Answer:

2.25

Step-by-step explanation:

The old width of 4 inches became a new width of 9 inches.

Old: 4 in.

New 9 in.

The old length of 6 inches became a new length of 13.5 inches.

Divide the new size by the corresponding old size.

9/4 = 2.25

13.5/6 = 2.25

You see in both cases, the scale factor is 2.25

The scale factor is 2.25

During martinez family trip they drove from home to a ski lodge a distance of 45 4/5 miles and then drove an additional 17 4/5 m
Fudgin [204]

Answer: the trip is 127 1/5 miles

Step-by-step explanation:

The distance that the martinez family drove from home to the ski lodge is 45 4/5 miles. Converting 45 4/5 miles to improper fraction, it becomes 229/5 miles.

Then, they drove an additional 17 4/5 miles to there friends house. Converting 17 4/5 miles to improper fraction, it becomes 89/5 miles

This means that the total distance that they drove while going is

229/5 + 89/5 = 318/5 miles

If the family drove the same route back home, then the distance traveled during there trip is

2 × 318/5 = 636/5 miles

Converting to mixed fraction, it becomes

127 1/5 miles

Solve the triangle give the measure of y
pishuonlain [190]

Given:

In triangle BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ.

To find:

The value of y.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Perpendicular}{Base}

In triangle BGU,

\tan B=\dfrac{GU}{BU}

\tan 44^\circ=\dfrac{7}{y}

0.966=\dfrac{7}{y}

Isolating y, we get

y=\dfrac{7}{0.966}

y=7.2463

y\approx 7.2

Therefore, the correct option is A.
