Camille buys a cake for $\$24.99$ . She also buys $12$ brownies. Each brownie costs the same amount. She spends $\$39.99$ on the cake and the brownies.
Camille finds the cost of each brownie by calculating $(39.99\ -\ 24.99)\ \div\ 12$ . Tanya finds the cost of each brownie by solving the equation $39.99\ +\ 12b\ =\ 24.99$ , where $b$ is the cost of each brownie.
Which approach uses the sequence of operations necessary to find the cost of each brownie: Camille’s, Tanya’s, both, or neither? Explain why.
Respond in the space provided.
Answer:
Camille's approach
Step-by-step explanation:
Each brownie costs $1.25. Tanya's equation is wrong because the end result is the cost of the cake and in order to get that you would need to subtract instead of adding.

Lily and Mackenzie collected some stamps. If Lily gave 4 stamps to Mackenzie, Mackenzie would have twice as many stamps as Lily. If Mackenzie gave 4 stamps to Lily, they would have the same number of stamps. How many stamps did each girl have?
GIVING BRAINLIEST. PLS HELP. SHOW UR WORK TOO
Answer: hope this helps ♡
Lily had 16 stamps and Mackenzie had 20 stamps.
Step-by-step explanation:
Lily gives 4 stamps to Mackenzie
(Mackenzie) m + 4 = 2(L - 4) (Lily)
Solve for Lily:
m + 4 = 2L - 8
m + 4 + 8 = 2L
(m + 12) ÷ 2 = 2L ÷ 2
(m + 12) ÷ 2 = L
L = (m + 12) ÷ 2 (we will substitute this value for L in the second equation)
Mackenzie gives 4 stamps to Lily
(Mackenzie) m - 4 = L + 4 (Lily)
m - 4 = ((m + 12) ÷ 2) + 4
m × 2 - 4 = ((m + 12) ÷ 2 × 2) + 4
2m - 4 + 4 = (m + 12) + 4 + 4
2m - m = (m - m + 12) + 8
m = 12 + 8
m = 20 (we will substitute this value of m in the next equation)
L = (m + 12) ÷ 2
L = (20 + 12) ÷ 2
L = 32 ÷ 2
L = 16

The formula for finding the volume of a rectangular prism is V = Bh. A rectangular prism with dimensions _________ will have a volume of 150 cubic units.
Answer: 10 * 5 * 3
Step-by-step explanation:
We want to find a base and a height that will multiply together to equal 150 [tex]units^{3}[/tex].
One solution is a [tex]B = 50 units^{3}[/tex] and [tex]h = 3 units^{3}[/tex].
Thus we need a length and width of the base that will multiply together to equal 50 [tex]units^{2}[/tex]. One solution is 10 units * 5 units.
Putting this all together, we have a solution of 10 units * 5 units * 3 units, which will have volume of 150 cubic units.

Tonya sampled 35 customers leaving the grocery store to find out how long they spend shopping. The results were that two people spent less than 15 minutes shopping, 28 people spent between 15 minutes and an hour shopping, and five people spent over an hour shopping.
Inference: Most customers spend less than an hour shopping.
Defend or challenge the inference with at least two complete sentences.
Answer:
challenge because it said 28 people spent between 15 and an hour if that is so the could have been there for an hour so there
Step-by-step explanation:
Answer:
The inference makes an incorrect statement.
Step-by-step explanation:
It is said that Tonya sampled 35 customers, where 28 of them spent 15-60 minutes, and 5 people spent over 60 minutes. This means that there are already 5 people that shop for over an hour. There may also be a bigger portion of shoppers that shop for exactly 60 minutes (1 hour), which is NOT less than 1 hour.
Hope that this helps! :)

Can someone please help me find the area of the figure.
Answer:
45.4
Step-by-step explanation:
→ Area of the polygon = Area of Square + Area of semi-circle
Area of square :
→ Area of square = Side × Side
→ Area of square = 6 m × 6 m
→ Area of square = 36 m [tex] \sf ^2[/tex]
Area of semi-circle :
→ Area of semi-circle = [tex] \sf \dfrac{Area \: of \: circle}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{\pi r^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times (3)^2}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{3.14 \times 3 \times 3}{2} [/tex]
→ Area of semi-circle = [tex] \sf \dfrac{28.26}{2} [/tex]
→ Area of semi-circle = 14.13 m[tex] \sf ^2[/tex]
⇒ Area of shape = ( 36 + 14.13 ) m[tex] \sf ^2[/tex]
⇒ Area of shape = 50.13 m[tex] \sf ^2[/tex]
Therefore,
Area of the shape is 50.13 m[tex] \sf ^2[/tex].11 ft
