Marvin is making lemon bread and pumpkin bread for a school bake sale. he needs 4 and 1/2 cups of flour for the lemon bread and 1 and 1/2 times as much flour for the pumpkin bread. he only has 2 and 1/8 cups of flour left in his pantry, so he buys a new bag from the grocery store. how much flour will marvin use from the new bag? write your answer as a whole number, fraction, or mixed number. simplify any fractions.
[tex]\frac{73}{8}[/tex] cups or [tex]9\frac{1}{8}[/tex] cups or 9.125 cups of flour will be used from new bag.
Flour required for lemon bread = [tex]4\frac{1}{2}[/tex] cups
Flour required for lemon bread = [tex]\frac{(4*2)+1}{2}[/tex]
Flour required for lemon bread = [tex]\frac{9}{2}[/tex] cups
Flour required for pumpkin bread = [tex]1\frac{1}{2} * \frac{9}{2}[/tex]
Flour required for pumpkin bread = [tex]\frac{(2*2)+1}{2}* \frac{9}{2}[/tex]
Flour required for pumpkin bread = [tex]\frac{5}{2}*\frac{9}{2}[/tex]
Flour required for pumpkin bread = [tex]\frac{45}{4}[/tex] cups
Now, the amount of flour Marvin already has = [tex]2\frac{1}{8}[/tex]
The amount of flour Marvin already has = [tex]\frac{(2*8)+1}{8}[/tex]
The amount of flour Marvin already has =[tex]\frac{17}{8}[/tex] cups
The amount of flour needed from new bag = [tex]\frac{45}{4}-\frac{17}{8}[/tex]
Taking LCM, we get 8
The amount of flour needed from new bag = [tex]\frac{(45*2)-17}{8}[/tex]
The amount of flour needed from new bag = [tex]\frac{90-17}{8}[/tex]
The amount of flour needed from new bag = [tex]\frac{73}{8}[/tex] cups
Hence, the amount of flour that will be used from new bag is [tex]\frac{73}{8}[/tex] cups or [tex]9\frac{1}{8}[/tex] cups or 9.125 cups.

An employee receives a 2% raise once per year. If the employee's initial salary is $52,400.00, What will the employee's salary be after 16 years?
The employee will receive a percentage raise after 16 years is $69,168
How to calculate the employee salary after 16 years ?The first step is to calculate the percentage raise of the salary per year
= 2/100 × 52,400
= 0.02 × 52,400
= 1,048
The next step is to multiply 1,048 by the number of years
= 1048 × 16
= 16,768
The salary after 16 years can be calculated as follows
= 52,400 + 16,768
= 69,168
Hence the employee salary after 16 years is $69,168

discount was on the cow? Please explain :)
Answer:
There was 60% discount on the cow.
Step-by-step explanation:
Cost of cow = $25Latest price = $15Discount can be calculated by dividing the latest price by the original price and multiplying by 100.
Thus,
percentage discount = 15/25 × 100
= 0.6 × 100
= 60%
Thus, there was 60% discount on the cow.

Three partners x,y and z contribute an amount of ksh 1400000 for an investment .The profit from the investment is to be shared based on the contribution of each.A profit of ksh 250000 after one month.If x got sh 60000, y got 110000 and the remainder was Z .Calculate the ratio of the contribution
Answer:
The ratio of the contribution x:y:z is 6:8:11
Step-by-step explanation:
Firstly, we need to know the amount in which Z got
That will be 250,000-x-y
= 250,000- 60,000 - 110,000 = 80,000
So the ratio of the contribution in x:y:z will be;
60,000:110,000:80,000
= 6:11:8

Landon left his house at time zero and drove to the store, which is 6 blocks away, at a speed of 3 blocks per minute. Then he stopped and went into the store for 7 minutes. From there, he drove in the same direction at a speed of 2 blocks per minute until he got to the bank, which is 4 blocks away from the store. He stopped at the bank for 5 minutes. Then he drove home at a speed of 5 blocks every minute. Make a graph of showing the number of blocks away from home that Landon is xx minutes after he leaves his house, until he gets back home.
Answer:
Step-by-step explanation:
The route Landon took starting at time t = 0 is
Home ⇒ Store ⇒ Bank ⇒ Home
Let's compute cumulative distances(in terms of blocks) and cumulative time using Landon's speed and stay at various places in order to plot a graph. (Note: cumulative means total so far; we add current value to previous total)
The graph will have cumulative time t (in minutes) on the X-axis and cumulative distance d (in terms of blocks) on the Y-axis. We will indicate Landon's position at any time with the coordinates (t, d)
At time t=0 Landon is at home so d = 0Q6: Women's heights have a mean of 63.6 inches and a standard deviation

Which equation has no solution?
O l-2x + 81 = 0
O [3x + 61 = 6
o 14x - 2) = -6
O 1-2 - x| = 9
Answer: |4x-2|=-6
Step-by-step explanation:
This has no solution
The equation that has no solution is | 4x - 2 | = -6.
What is an equation?Two algebraic expressions having the same value and symbol '=' in between are called an equation.
| -2x + 8 | = 0: This equation has only one solution, which is x = 4. When we take the absolute value of any number, the result is always non-negative (i.e., greater than or equal to zero).
Therefore, the absolute value of -2x + 8 can only be zero if -2x + 8 itself is zero. Solving for x, we get x = 4.
| 3x + 6 | = 6: This equation has two possible solutions, which are x = 0 and x = -4. When we take the absolute value of 3x + 6, the result can be either positive or negative, depending on the value of x.
Therefore, we need to solve two separate equations: 3x + 6 = 6 and 3x + 6 = -6. Solving for x in each case, we get x = 0 and x = -4.
| 4x - 2 | = -6: As I mentioned in my previous answer, this equation has no solutions.
An absolute value cannot be negative or equal to a negative number, so there is no value of x that would make the left-hand side of the equation equal to -6.
| -2 - x | = 9: This equation has two possible solutions, which are x = -11 and x = 7. When we take the absolute value of -2 - x, the result can be either positive or negative, depending on the value of x.
Therefore, we need to solve two separate equations: -2 - x = 9 and -2 - x = -9. Solving for x in each case, we get x = -11 and x = 7.
