The students in a club are selling flowerpots to raise money. Each flowerpot sells for $21. Part A Write an expression that represents the total amount of money, in dollars, the students raise from selling x flowerpots. Enter the expression in the box provided. Enter only your expression.
Answer: y = 21x
Step-by-step explanation:
y in this expression represents the total amount of money, in dollars, the students raise from selling x flowerpots.
21 is the price of each flower pot.
x is the number of flower pots sold.
If for instance, they sold 30 flower pots, y(total amount in dollars) would be;
= 21x
= 21 * 30
= $630

whats the question?????
Answer:the question is chemistry and the sander is math
Step-by-step explanation:
A ball is thrown from the top row of seats in a stadium. The function h(t) = - 16t^2 + 80t + 96 gives the height, in feet, of the ball t seconds after it is thrown. How long will it be before the ball hits the ground?
Answer:
2s or 3s
Step-by-step explanation:
Given the function that models the height of the object as;
h(t) = - 16t^2 + 80t + 96
The ball reaches the ground when h = 0
Substitute
0 = - 16t^2 + 80t + 96
Divide through by -16
0 = t²-5t-6
t²-5t-6 = 0
t²-2t-3t+6 = 0
t(t-2)-3(t-2) = 0
(tt-2)(t-3) = 0
t - 2 = 0 and t-3 = 0
t = 2 and 3s
Hence it will take the ball 2s or 3s to reach the ground

Answer: Domain: {-3, oo) and Range: {0,oo)
Hilda adds 5 to a number, then multiplies the sum by -2. The result is 6. Write an equation to find the number, x. What is the number?
Answer: -8
Step-by-step explanation:
If we add 5 to -8, that will be -3. Then if we multiply -3 with -2, it equals 6 because when two negatives multiply with one another the answer will be positive.
So in conclusion, the number is -8.

Answer:
3 trays of corn muffins and 2 trays of bran muffins
Step-by-step explanation:
c = 4m + 3w
b = 2m + 3w
16m and 15w
1 tray of corn muffins and 4 trays of bran muffins = $11
16 - 4 = 12
15 - 3 = 12
12 - 8 = 4
12 - 12 = 0
b = $2
c = $3
c = 3 x 1 = 3
b = 2 x 4 = 8
3 + 8 = 11
-----------------------------------------------------------------------------------------------------------------
2 trays of corn muffins and 3 trays of bran muffins = $12
c = 4m + 3w
b = 2m + 3w
16 - 8 = 8
15 - 6 = 9
8 - 6 = 2
9 - 9 = 0
b = $2
c = $3
c = 3 x 2 = 6
b = 2 x 3 = 6
6 + 6 = 12
-----------------------------------------------------------------------------------------------------------------
3 trays of corn muffins and 2 trays of bran muffins = $13
c = 4m + 3w
b = 2m + 3w
16 - 12 = 4
15 - 9 = 6
4 - 4 = 0
6 - 6 = 0
c = 3 x 3 = 9
b = 2 x 2 = 4
9 + 4 = 13
-----------------------------------------------------------------------------------------------------------------
4 trays of corn muffins and 0 trays of barn muffins = $12
c = 4m + 3w
b = 2m + 3w
16 - 16 = 0
15 - 12 = 3
c = 3 x 4 = 12
b = 2 x 0 = 0
12 + 0 = 12
What is the solution to 8(2^x+3)=48
16/3=48
Step-by-step explanation:
evaluate
happy holidays
The solution to the equation 8(2ˣ + 3) = 48 is x = 0.
Here, we have,
To solve the equation 8(2ˣ + 3) = 48, we can follow these steps:
Distribute the 8 to both terms inside the parentheses:
8 * 2ˣ + 8 * 3 = 48
Simplify the equation:
2⁽ˣ⁺³⁾ + 24 = 48
Subtract 24 from both sides to isolate the exponential term:
2⁽ˣ⁺³⁾ = 48 - 24
2⁽ˣ⁺³⁾ = 24
Rewrite 24 as a power of 2:
2⁽ˣ⁺³⁾ = 2³ * 3
Apply the property of exponentiation, where if two powers with the same base are equal, then their exponents must be equal:
x + 3 = 3
Solve for x by subtracting 3 from both sides:
x = 0
Therefore, the solution to the equation 8(2ˣ + 3) = 48 is x = 0.

Which value completes the equation?
56,000÷_____ = 800
Answer:
Answer is 70
Step-by-step explanation:
Let's see here. 7 times 8 equals 56 and there's a 56 with 3 zeroes. 70 times 800. 7 times 8 equals 56 then add the 3 zeroes which gives us 56,000 which tells us that 70 is the correct answer.
Find the missing values in each row. Use the percent equation. A: Principal: $100 Interest rate: 5% Time in years: 3 Interest earned: B: Principa;" $500 Interest rate: 4% Time in years: interest earned: $20 C: Principal: Interest rate:10%% Time in years: 7 Interest earned:$35 D: Principal: $200 Interest rate: Time in years:2 Interest earned: $6
Answer:
A.) 15
B.) 1 year
C.) $50
D.) 1.5%
Step-by-step explanation:
The percentage equation goes thus:
Interest earned = principal * rate * time
A)
Principal: $100 Interest rate: 5% Time in years: 3 Interest earned
Interest earned = $100 * 0.05 * 3
Interest earned = $15
B.)
Principa;" $500 Interest rate: 4% Time in years: interest earned: $20
Interest earned = principal * rate * time
20 = 500 * 0.04 * time
20 = 20 * time
Time = 20 / 20 = 1
Time = 1 year
C.)
Principal: Interest rate:10% Time in years: 7 Interest earned:$35
Interest earned = principal * rate * time
$35 = principal * 0.1 * 7
$35 = principal * 0.7
Principal = $35 / 0.7
Principal = $50
D.)
Principal: $200 Interest rate: Time in years:2 Interest earned: $6
Interest earned = principal * rate * time
$6 = $200 * rate * 2
$6 = $400 * rate
Rate = $6/$400
Rate = 0.015 = 1.5%

Bag Ladies, Inc. Manufactures two kinds of bags—totes and satchels. The company allocates manufacturing overhead using a single plantwide rate with direct labor cost as the allocation base. Estimated overhead costs for the year are $25,500. Additional estimated information is given below. Totes Satchels Direct materials cost per unit $33 $40 Direct labor cost per unit $53 $61 Number of units 530 360 Calculate the amount of overhead to be allocated to Totes. (Round any percentages to two decimal places and your final answer to the nearest dollar.)
Answer:
Allocated MOH= $14,312
Step-by-step explanation:
Giving the following information:
Estimated overhead costs for the year are $25,500.
Totes Satchels:
Direct labor cost per unit $53 $61
Number of units 530 360
First, we need to calculate the allocation rate:
Predetermined manufacturing overhead rate= total estimated overhead costs for the period/ total amount of allocation base
Predetermined manufacturing overhead rate= 25,500 / (53*530 + 61*360)
Predetermined manufacturing overhead rate= 25,500/50,050
Predetermined manufacturing overhead rate= $0.5095 per direct labor dollar
Now, we can allocate overhead to Totes:
Allocated MOH= Estimated manufacturing overhead rate* Actual amount of allocation base
Allocated MOH= 0.5095*(53*530)
Allocated MOH= $14,311.855
