chef johnson used 4 1/2 cups of flour to make 4 fruitcake. how many cups of flour are needed for 1 fruitcake
Answers
Answer:
1 1/8 Cups of flour are needed for 1 fruitcake.
Step-by-step explanation:
This is because if you divide 4 1/2(the amount of flour used for four cups) by 4 (the amount of fruitcakes he made) you would get 9/8 or 1 1/8 which is what you use for 1 fruitcake. I hope this helped!

I haven't done these in 2 years and I'm not sure if I remember things correctly but here's what I would put down.
5) No, it is not because the sizes of each section are not even.
6) Yes, this is fair since there are a even chance of getting each number.
7) 3 out of 25 or 3/25
8) The bag with 250 colored tiles would give him a less chance of picking a blue tile. In the first bag, there is a 40% chance that Greg would pick a blue tile while the second bag, he would have a 30% chance of picking a blue tile. To get these percentages, I divided the the amount of blue tiles in the bag by the total amount of tiles.
Explantion for question 8: 10 blue tiles in a bag of 25 so you would do 10/25 which is .4 and as a percentage it would be 40%. For the second question, 75 blue tiles out of 250 total so 75/250 and that would be .3 and as a percentage, it would be 30%. The "/" is a fraction bar and is sometimes used as a division symbol as well, just in case you don't know:)

Ophelia keeps flour in a cylindrical canister. The capacity of the full canister is 75.36 in^3..When it is filled halfway the flour reaches a height of 3 in. What is the diameter of the canister?
Answers
Answer:
4 (rounded to the nearest whole number)
Step-by-step explanation:
total height = 3 x 2 = 6
Volume = radius^2 * pi * height
75.36= radius^2 * pi * 6
75.36/pi = radius^2 * 6
23,987833 = radius^2 * 6
23,987833/6 = radius^2
3,997972 = radius^2
radius = 1,999493
diameter = radius x 2 = 1,999493 x 2 = 3,998986

Hint: Triangles have 3 sides.
Answers
(4x - 3) + (4x - 3) + (4x - 3) = 63
Remove parentheses
4x - 3 + 4x - 3 + 4x - 3 = 63

12x - 9 = 63
12x = 72, x = 6
Solution: x = 6

Answers
Answer:
x = -8
Step-by-step explanation:
3(1.5x + 9) = -9
Divide both sides by 3
1.5x + 9 = -3
Subtract 9 from both sides
1.5x = -12
Divide both sides by 1.5
x = -8
Answer:
x = -8Step-by-step explanation:
3(1.5x + 9)= -9

Let’s split this triangle in the middle to get two right triangles.
The height of the triangle is 12 units and one of the legs is 5 ( from 10/2 )
Let’s find the hypotenuse
(5) ^2 + (12) ^2 = c^2
C = 13
So this mean each side is 13 units
13 + 13 + 10 = 36 units
Perimeter = 36 units

Answer:
down below.
Step-by-step explanation:
One–third of the product of −8 and 9 = -24
-8(9) = -72
-72 / 3 OR -72(1/3) = -24
Half the sum of 8 and −6 = 1
8 + (-6) =2
2 / 2 = 1
Three times the sum of 12 and −6 = 18
12 + (-6) = 6
6 * 3 = 18
One-fifth the product of 1 and −5 = -1
1(-5) = -5
-5/5 = -1
Five times the sum of −8 and 4 = -20

Betsy started a business 2 years ago. She had 8 customers in the first year. She added 18 customers in the second year. Betsy's goal is that in each of the next 4 years, she will have three times ad many customers as the year before. Betsy shows her calculations in the TABLE below that if she meets this goal each year, she will have 312 customers 4 years from now. is Betsy correct? Use the drop-down menus to explain your reasoning.
Expression: (8 + 18) * 3^4
Step 1: 26 * 3^4 <<< TABLE
Step 2: 26 * 12
Answer: 312
Pick the correct answer in parentheses:
Betsy's calculations in Step 1 are ( is she Correct or Incorrect) because... ( .She added incorrectly .She has 26 customers at the end of her second year .She should have multiplied 18 * 3^4 before adding 8)
Besty's calculations in Step 2 are ( is she Correct or Incorrect) Because.... ( .She did not find the correct value of 3^4 .26 * 3^4 = 26 * 12 .She did not apply the order of operations correctly)
If Betsy reaches her goal each year, she will have.. ( .2,106 .312 .1,466) customers 4 years from now.
Answers
Answer: step one is correct and the second step is incorrect
Step-by-step explanation:
Answer:
Betsy isn't correct. Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.
Step-by-step explanation:
26 × 3 × 4 is different from 26 × 3⁴
- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.
- Betsy started her business 2 years ago.
- In the first year, Betsy has 8 customers.
- In the second year, Betsy added 18 customers,
- So, her customers are now 8+18 = 26
- Betsy's goal is that in each of the next 4 years, she will have three times as many customers as the year before.
If the base number of customers is truly 26 this year,
Next year, Betsy would have 26 × 3 = 78 customers.
In 2 years, she would have 78 × 3 = 234
Thus indicating that in t years from now, the number of her customers will be
N(t) = N₀ × 3ᵗ
where
N(t) = number of customers t time from now
N₀ = number of customers at the moment = 26
t = number of years from now.
N(t) = 26 × 3ᵗ
In 4 years from now, Betsy will have
N(t=4) = 26 × 3⁴ = 2,106
So, it is evident that Betsy's calculations are wrong as she made her calculations by multiplying the base number of customers by 3 and then summing it all up for the 4 years under review instead of a continuous multiplication by 3.
26 × 3 × 4 is different from 26 × 3⁴
- If Betsy meets her target for the next 4 years, she will have 2106 customers in 4 years time.

In the photo is an example of a net of a rectangular prism.
Surface area is the measure of the total area of the surface of a 3D object. For example, if I have a cube, the surface area would be the area of the outside of the cube.
