The length of a new rectangular playing field is 4 yards longer than triple the width. if the perimeter of the rectangular playi
jasenka [17]
The length is 4 yards longer than 3width so L = 3W+4
perimeter equal 408 yards

perimeter equal 2L +2W = 2(3W+4)+2W 

408 = 6W +8 +2W
400=8W

W = 50

L = 3*50 +4 = 154

L = 154
W = 50

P = 2L +2W
408 = 2*50 +2*154
408 = 100 +308
408 = 408

hope that this is easy understandably

I need help. Someone please help. The second and third picture are to the same problem. Just please help me I'm dumb.

By listing the samples in descending order we have - Sample B, Sample E, Sample A, Sample C, and Sample D.

Step-by-step explanation:

Step 1; First, we must convert all the temperatures into a common scale. The given temperatures are in three different units i.e. °C, K, and °F. Here we convert all the units into K.

To convert °C to K, we add 273.15 with the °C , 44 °C= 44 + 273.15 =     317.15 K.

To convert °F, we have the formula (112°F − 32) × (\frac{5}{9}) + 273.15, so

110 °F = (110 - 32) × (\frac{5}{9}) + 273.15 = 316.483 K,

112 °F = (112 - 32) × (\frac{5}{9}) + 273.15 = 317.594 K.

Step 2; By rewriting all the values on the same unit, we get;

Sample A = 317.15 K,

Sample B = 320 K,

Sample C = 316.483 K,

Sample D = 310 K,

Sample E = 317.594.

The descending order is as follows 320 K, 317.594K, 317.15 K, 316.483 K and 310 K which is Sample B, Sample E, Sample A, Sample C, and Sample D.

Michelle’s house is 22 miles due north of Jan’s house and 30 degrees northeast of Richard’s house. Richard’s house is due east o
tensa zangetsu [6.8K]

Answer:

Michelle’s house is 44 miles to Richard’s house.

Step-by-step explanation:

The distance can be found out by using the trigonometric ratio of sine theta

Sine theta= Perpendicular/ Hypotenuse

We know the values of hypotenuse and theta

Sine 30 = 22/ Hypotenuse

Hypotenuse= 22/ sine 30

Hypotenuse= 22/0.5

Hypotenuse = 44

The hypotenuse marks the distance between Michelle’s house to Richard’s house. Due east means counter clockwise rotation from east.
