Louise has a television in her family room that is 3 feet wide and 5 feet long. She has a television that is similar in shape in her bedroom that is 1.5 feet long. What is the perimeter of the television in Louise's bedroom?

Answers

Answer:

The perimeter of the TV = 8 feet

Step-by-step explanation:

The keywords in this question are "similar in shape". This means that the dimensions of the two TVs are equivalent, but they are not the same.

TV in family room = 3 feet wide, 5 feet long = 3/5

TV in bedroom = 1.5 feet wide, x feet long = 1.5/x

Since the TVs are similar:

[tex]\frac{3}{5} = \frac{1.5}{x} \\cross-multiplying:\\3 \times x = 5 \times 1.5\\3x = 7.5\\x = \frac{7.5}{3} \\x = 2.5\ feet[/tex]

Therefore the TV in bedroom is 1.5 feet long and 2.5 feet wide.

Perimeter of a TV = perimeter of a rectangle

Perimeter of a rectangle = (2 × Length) + (2 × width)

Perimeter = ( 2 × 1.5) + ( 2 × 2.5)

= 3 + 5 = 8 feet

One year, a certain city experienced a
low temperature of -15°F and a high
temperature of 110°F. What is the
difference in temperature from the
lowest to the highest?
[?] F

Answers

Answer:

Step-by-step explanation:

there is a 125 degree difference between the two

The difference in temperature from the lowest to the highest is 125°F.

Given that, one year, a certain city experienced a low temperature of -15°F and a high temperature of 110°F.

To find the difference in temperature from the lowest to the highest, we need to subtract the low temperature from the high temperature.

The difference will be in Fahrenheit (F):

Difference = High temperature - Low temperature

Difference = 110°F - (-15°F)

Difference = 110°F + 15°F

Difference = 125°F

So, the difference in temperature from the lowest to the highest is 125°F.

Answer:

40 miles per hour.

Step-by-step explanation:

[tex]\frac{1}{4}[/tex] ÷ 22.5 = [tex]\frac{1}{4}[/tex] × [tex]\frac{2}{45}[/tex] = [tex]\frac{1}{90}[/tex] mile per second

[tex]\frac{1}{90}[/tex] × 3600 = 40 miles per hour.

A.

You have to convert 22.5 seconds to hours

1st you have to go from seconds -> minutes:
22.5 seconds x 1min / 60secs = 0.375mins

2nd go from minutes to hours:
0.375mins x 1hr / 60minutes = 0.00625hours

Since it is miles per hour, miles would go on top and hours (or seconds in this this case) would go on the bottom.

To find miles per hour:

(1/4) miles / 0.00625 hours = 40 miles per hour.

Therefore, hyena runs 40 miles per hour.

PLS HELPPPPPP MATH!!!!!!!!!!

Answers

Answer:

option C

Step-by-step explanation:

Let ABC be the smallest triangle where

AB = 2cm ; BC = 4cm ; AC = 3cm

ABC = h° ; ACB = g° ; BAC = i °

Let XYZ be the largest triangle where

XY = 4cm ; YZ = 8cm ; XZ = 6cm

XYZ = f ° ; YZX = e°

It's given that ABC & XYZ are similar . So ,

[tex] \frac{AB}{XY} = \frac{BC}{YZ} = \frac{AC}{XZ} [/tex]

=> (AB & XY) ; (BC & YZ) ; (AC & XZ) are corresponding sides.

=> (ABC & XYZ) ; (ACB & YZX) ; (BAC & YXZ) are corresponding angles.

Hence,

(h & f) ; (e & g) are corresponding angles
