True. Parallel lines have the same slope and will never intersect.

Lucy bought a 12 pound watermelon for $6.24.

Leokris [45]

Answer:

Part A: $0.52

Part B: $3.64

Step-by-step explanation:

Divide $6.24 by 12 pounds to determine the cost per pound

$6.24/12=0.52$

Multiply $0.52 by 7 pounds to find the cost for a 7-pound watermelon

$0.52*7=3.64$

3) Valerie works at a local amusement park. She earns $9.80 per hour. She 20 points

NemiM [27]

<h3>Answer: Choice A</h3><h3>9.80h+10 = 88.40</h3>

===========================================================

Work Shown:

h = number of hours worked.
9.80h = amount of money earned after working h number of hours (ignoring the meal bonus).
9.80h+10 = total amount of money earned after adding on the meal bonus.
9.80h+10 = 88.40 is the equation we use since the total 9.80h+10 is the same as the total she earned 88.40 dollars.

--------------------

Extra info (optional section)

If you want to solve for h, then you could follow these steps.

9.80h+10 = 88.40

9.80h = 88.40-10 ... subtract 10 from both sides

9.80h = 78.40

h = 78.40/9.80 .... divide both sides by 9.80

h = 8

Valerie worked 8 hours on Friday.

As a check,

9.80h + 10 = 88.40

9.80*8 + 10 = 88.40

78.40 + 10 = 88.40

88.40 = 88.40

The answer is confirmed.

Hey there!

The answer to your question is $95.55$

Formulas:

Area of semi-circle = $\frac{1}{2}(\pi r^2)$

Area of rectangle = $lw$

Area of triangle = $\frac{bh}{2}$

Now solve:

semi-circle

$\frac{1}{2}\pi3^2$

$\frac{1}{2}\pi9$

$4.5\pi$

(We will use 3.14 as approx. for pi)

$4.5 * 3.14\\23.55$

rectangle

$10(6)\\60$

triangle

$\frac{4(6)}{2}$

$\frac{24}{2} \\12$

Now add them all together:

$23.55+60+12\\95.55$

Have a terrificly amazing day!

Carl collects coins compulsively, but he only likes quarters and dimes. Carl currently has 125 coins for a total of $26.00. How

faust18 [17]

We need to find the two equations that represents the total amount of coins Carl has that makes $26.00 and the number of quarters and dimes.

Carl has 35 dimes and 90 quarters. The equations are $0.1x+0.25y=26$ and $x+y=125$ .
