At some point, she will sell enough cards so that her sales cover her expenditures. So, the correct answer is ($40)
<h3> How did we figure this out?</h3>
Lola is making greeting cards, which she will sell by the box at an arts fair. She paid $50 for a booth at the fair, and the materials for each box of cards cost $8. She will sell the cards for $10 per box of cards.
We are going to use 50, 8 and 10 to find are answer.
Therefore, we are going to divide the numbers:
- Division problem
- 50/10
- 8 x ? = 40
<h3 /><h3>What is the missing number?</h3>
First, we need to figure out 50/10:
Therefore, at some point, she will sell enough cards so that her sales cover her expenditures. So, the correct answer is ($40)
Answer:
The inverse is 1/2x -3/2
Step-by-step explanation:
y =2x+3
Exchange x and y
x = 2y+3
Solve for y, subtracting 3 from each side
x-3 = 2y+3-3
x-3 =2y
Divide each side by 2
(x-3)/2 = 2y/2
1/2x - 3/2 =y
The inverse is 1/2x -3/2
Answer:
{Red,Blue}
Step-by-step explanation:
Since the experiment consists of randomly drawing just a cube from a bag containing three red and two blue cubes, the outcome could be either a red or blue cube. Therefore the sample space is:
{Red,Blue}
Answer:
1260 cm^2
Step-by-step explanation:
To find the area of the rectangle we need its base and its height and calculate the product A = (base)(height).
Here the height of the triangle is found using the Pythagorean Theorem:
37^2 = |AB|^2 + 12^2, or |AB|^2 = 1369 - 144, or 1225.
Taking the square root of both sides, we get |AB| = √1225 = 35 cm = height of rectangle.
Since BC:CD = 1:2, and since |BC| = 12 cm, |BD| is 12 cm + 24 cm = 36 cm.
Thus the length of the rectangle is 36 cm.
The area of the rectangle ABDE is (36 cm)(35 cm) = 1260 cm^2
Answer:
(Choice A) 2(3d+3) & (Choice C) (3d+3)+(3d+3)
Step-by-step explanation:
<--- A is correct
< --- B is NOT correct
by associative and commutative properties
so C is correct
A and C are both correct.
