Answer: Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.

Step-by-step explanation:

Given:  Rachel bought 12 rolls of packing tape and paid a total of $33.60.

Therefore, the unit rate of tape bought by Rachel = \frac{33.60}{12}=\$2.8

Hence, the unit rate of tape bought by Rachel =$2.8

From the table , Kevin bought 2 rolls of packing tape and paid a total of $ 6.40.

The unit rate of tape bought by Kevin =\frac{6.40}{2}=3.2

Hence,  the unit rate of tape bought by Kevin = $3.2

Clearly, 3.2>2.8

Therefore, Rachel's unit rate is less than Kevin's because 3.2 is greater than 2.8.

Pls help :Find the missing side or angle.<br> Round to the nearest tenth.
Nitella [24]

Answer:

C° = 71.6056

Step-by-step explanation:

Law of Cosines: c² = a² + b² - 2abcosC°

Step 1: Plug in known variables

29² = 30² + 15² - 2(30)(15)cosC°

Step 2: Evaluate

841 = 900 + 225 - 900cosC°

-59 = 225 - 900cosC°

-284 = -900cosC°

71/225 = cosC°

cos⁻¹(71/225) = C°

C° = 71.6056

And we have our answer!

The length of a rectangle is one more that three times its width. If the perimeter is 42 inches, find the dimensions of the rect
Liono4ka [1.6K]
Let w=width
L= length
3w+1=l
Perimeter -2(l+w)
2(W+3w+1)=42
Divide both sides by 2
W+3w+1=21
Subtract 1
W+3w=20
Add like terms
4w=20
Divide both sides by 4
W=5
The width is 5 inches

3w+1=l
Input the width into the equation
3(5)+1=l
15+1=l
16=l
The length of the rectangle is 16 inches

The rectangle is 5 x 16 inches

A store was keeping track of how many bottles of hand sanitizer and soap bars were sold last week. A bottle of hand sanitizer co
agasfer [191]

Answer:

Hand sanitizer=135 bottles

Bar soap=83 bottles

Step-by-step explanation:

Let x represent the hand sanitizer and y the sop.

-Our problem can be expressed as:

x+y=218\ \ \ \ \  ...i\\\\4.25x+2.15y=752.20\ \ \ \ \  ...ii

#Make x the subject in i then substitute in ii to solve;

x=218-y\\\\\therefore 4.25(218-y)+2.15y=752.20\\\\926.5-4.25y+2.15y=752.20\\\\174.3=2.1y\\\\y=83\\\\x=218-83=135

Hence, 135 bottles of hand sanitizer and 83 bottles of bar soap were sold.
