Answers
Jessica has the option to switch to a plan that charges $65.00 per month with unlimited text messages.
Jessica typically sends about 900 text messages per month.
Cost per message under the new plan = $65 / 900 = $ 0.072 per message
It make sense for her to switch to the new plan only if the cost per message in her existing plan is more than $ 0.072

Christopher Christopher just found beautiful yarn for 20% off at his favorite yarn store. He can make one scarf from 2/3 of a ball of yarn. If Christopher buys 12 balls of yarn, how many scarves can he make
Answers
12/.6 repeating = 18
13 balls of yarn would be used to make 18 scarves.
Let's convert 2/3 to a decimal and then divide 12 balls of yarn by that.
To convert a fraction to a decimal, we must divide its numerator by its denominator.
2 ÷ 3 = 0.67 (6 Repeating)
Now, divide 12 yarn balls by this:
12 ÷ 0.67 (Repeating) = 17.91 (Repeating decimal)

There's no need for a system of linear equations if you were to solve a real life problem like this. In calculus, they don't give a rat about HOW you get your answer to an easy algebra 1 equation, as long as you used one of the correct methods and got the right answer.
Best of luck my friend. :)
A linear equation of one variable is expressed in the form of ax + b = 0, where a and b are the two integers, and x is a variable.
In the given question, the linear equation can be represented as:
2x + 10 + x = 73.
The number of dogs is 21, and the number of cats available is 52.
Given that:
Total number of dogs and cats = 73
Let the number of dogs be x.
The number of cats, as given is = 10 + 2x
Now, solving for the equation:
x + 10 + 2x = 73
Solving for the variables:
3x + 10 = 73
3x = 73 -10
3x = 63
x = [tex]\dfrac {63}{3}[/tex]
x = 21
The number of dogs available is 21.
The number of cats available is:
2x + 10
Putting the value of x:
2 (21) + 10
52
Thus, the number of dogs is 21, and the number of cats available is 52.

A trapezoid window has a height of 18 centimeters. The bases of the window are 34 and 28 centimeters long. What is the area of the window?
Answers
The area of the trapezoid window is 396cm sq.
The area of a trapezoid window can be calculated using the formula:
Area = 1/2 x (base1 + base2) x height
Plugging in the values:
base1 = 34 cm
base2 = 28 cm
height = 18 cm
Area = 1/2 x (34 + 28) x 18 = 396 cm²

dennis wants to buy a card for his wife. dennis calculates the amount of the card as $4.50. the actual price of the card is $4. what is Dennis's percent error?
Answers
To find the percent error, divide the error by the actual price and multiply by 100 %. Hence, $.50/$4 =.125 x 100 = 12.5 %.
Dennis' percent error is 12.5 %.
Final answer:
Dennis's percent error in estimating the price of the card is 12.5%, calculated by taking the difference between his estimate and the actual price, dividing by the actual price, and then multiplying by 100.
Explanation:
Dennis calculated the amount of the card as $4.50, but the actual price is $4.00. To find Dennis's percent error, we'll need to calculate the difference between his estimated price and the actual price, and then divide that by the actual price. Finally, we'll multiply that number by 100 to get the percent error.
Here's how we'll calculate it:
Divide the error by the actual value: $0.50 ÷ $4.00 = 0.125.
Multiply by 100 to convert to a percentage: 0.125 × 100 = 12.5%.
The percent error in Dennis's estimate is 12.5%.
The length of a rectangle is 6 inches more than it’s with the perimeter of the rectangle is 24 inches what is the width and length of the rectangle
Answers
L= W+6= length
P= 24 inches
Perimeter= 2(W + L)
substitute L= W+6 for L
24= 2(W +(W+6)
combine like terms in parentheses
24= 2(2W + 6)
multiply 2 by all in parentheses
24= (2*2W) + (2*6)
24= 4W + 12
subtract 12 from both sides
12= 4W
divide both sides by 4

W= 3 inches
L= W+6= 3+6= 9 inches

What is the value of the expression, written in standard form? (6.6x10^-2)/(3.3x10^-4)

Wesley walked 11 miles in 4 hours if he walked the same distance every hour , how far did he walk in one hour
Answers
Wesley walked 2.75 miles in one hour, calculated by dividing the total distance (11 miles) by the total time (4 hours).
The question asks how far Wesley walked in one hour if he walked 11 miles in 4 hours at a consistent pace. To find this, we can calculate his average speed by dividing the total distance by the total time. This gives us an equation: Average speed = Total distance / Total time, which simplifies to: Average speed = 11 miles / 4 hours.
Performing the division, we get an average speed of 2.75 miles per hour. Therefore, Wesley walked 2.75 miles in one hour.

What number could be added to 0.40 mL for the level of precision to be 0.01mL
Answers
Answer:
- 0.39
Step-by-step explanation:
Level of precision = 0.01 mL
We need to find a number which could be added to 0.40 mL for the level of precision to be 0.01 mL .
Let x be a number which could be added to 0.40 mL for the level of precision to be 0.01 mL .
[tex]x+0.40=0.01[/tex]
On subtracting 0.40 from both sides , we get
[tex]x+0.40-0.40=0.01-0.40[/tex]
On solving , we get
[tex]x+0=0.01-0.40[/tex]
We know that [tex]x+0=x=0+x[/tex] where 0 is the additive inverse .
So,
[tex]x=0.01-0.40[/tex]
Here , [tex]0.01-0.40=-0.39[/tex]
Therefore ,
[tex]x=0.01-0.40=-0.39[/tex]
Therefore , -0.39 could be added to 0.40 mL for the level of precision to be 0.01mL

First, find the area of the triangle:
The formula of the area of a triangle, "A":
A = (1/2) * b * h ;
in which: " A = area (in units 'squared') ; in our case, " yd² " ;
" b = base length" = 6 yd.
" h = perpendicular height" = "(4 yd + 4 yd)" = 8 yd.
___________________________________________________
→ A = (1/2) * b * h = (1/2) * (6 yd) * (8 yd) = (1/2) * (6) * (8) * (yd²) ;
= " 24 yd² " .
___________________________________________________
Now, find the area, "A", of the square:
The formula for the area, "A" of a square:
A = s² ;
in which: "A = area (in "units squared") ; in our case, " yd² " ;
"s = side length (since a 'square' has all FOUR (4) equal side lengths);
A = s² = (4 yd)² = 4² * yd² = "16 yd² "
_________________________________________________
Now, we add the areas of BOTH the triangle AND the square:
