Answer:

I am sorry but if this is wrong but i think it is either 21,because it is divisible by 3 and 12 / 3 = 4 which is a denominator

Step-by-step explanation:

21 because it is divisible by 3 and 12 / 3 = 4 which is a denominator.

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

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! :)

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.

Answer:

I don't know the answer but I can give you a hint it has to be bigger than 60 and smaller than 110

Answer:

If this is a trapezoid then the total angles on the inside should be 180 degrees.

Step-by-step explanation:

That means the sum of a and b is 60. With a being 30 degrees and b being 30 degrees.

Answer:

[tex]a + 95 \degree + 53\degree = 180\degree \\ a = 180\degree - (95 + 53)\degree \\ a = 32\degree[/tex]

Step-by-step explanation:

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]

Answer: 80

Step-by-step explanation:

Looking at the ratios in the table, the number of days to number of questions is 1:5 (4x5=20; 8x5=40;11x5=55). So for 16 days it will be 16x5=80

Answer:

i think it would be D

Step-by-step explanation:

Answer:

D or 6/121

Step-by-step explanation:

And there are three orange crayons out of 11

that would mean you would multiply 11 by 11 for the probability of doing both of them

and you would multiply two and three for the probability of doing both of them

The answer is D, or 6/121

Answer:

The speeds are 88 / 9, 92 / 11, and 96 / 13

Step-by-step explanation:

Since we are already given the equation here, we can plug in the given speeds to find the times. Plugging in 45 will give t = 2 + 350 / 45 which is 2 + 70 / 9. 2 = 18 / 9. We get the time is 88 / 9. Plugging in 55 will give t = 2 + 350 / 55 = 2 + 70 / 11. 2 = 22 / 11. The time is 92 / 11. Plugging in 65 will give t = 2 + 350 / 65 = 2 + 70 / 13. 2 = 26 / 13. The time is 96 / 13.

Answer:

88 -- 9, 92 -- 11, 96 -- 13
