A florist has to pay $7.50 each time a customer chooses a competitor for the delivery of flowers. Which expression shows the amount that the florist earns if p people use a competitor for delivery, and the company makes $320.00 before any payment is made to their competitors?
320 minus 7.50 p
320 + 7.50 p
7.50 p minus 320
7.50 p + 320
Answer:
320 minus 7.50 p
Explanation:
the florist earned 320 dollars and then lost money due to having a competitor deliver, since we dont know the amount of people who chose competitors we use the term p next to the amount that p is worth because each time a customer uses a competitor it costs 7.50 out of the original 320.

How much fertilizer containing 30% nitrogen should be mixed with a fertilizer containing 10% nitrogen to get 10L of a fertilizer containing 12% nitrogen?
Answer:
1L of 30% fertilizer and 9L of 10% fertilizer
Step-by-step explanation:
Let x = the amount of fertilizer containing 30% nitrogen.
Let y = the amount of fertilizer containing 10% nitrogen
x + y = 10 because the two fertilizers together will be 10L
0.3x will be the amount of nitrogen in the 30% nitrogen fertilizer, and 0.1y will be the amount of nitrogen in the 10% fertilizer. If you add those together, you will get 12% of the nitrogen in the 10L mixture. This makes this equation:
0.3x + 0.1y = 0.12(10)
0.3x + 0.1y = 1.2
Now we have our two equations.
x + y = 10
0.3x + 0.1y = 1.2
We can use substitution to solve this system of equations.
x = 10 - y
Substituting this into the second equation, we have:
0.3(10-y) + 0.1y = 1.2
3 - 0.3y + 0.1y = 1.2
3 - 0.2y = 1.2
1.8 = 0.2y
9 = y
10 - 9 = 1L
There will be 9L of 10% nitrogen fertilizer and 1L of 30% nitrogen fertilizer.
For every 4 regular sodas sold at a market, there are 2 diet sodas sold. What is the ratio of diet sodas sold to the total number of sodas sold?
Answer:
1/3
Step-by-step explanation:
The total number of sodas sold is 6, which means the amount of diet soda compared to that is 2/6. This can be further simplified to 1/3.
Find the derivation of y=sin (2x2 + 3x-4)<br />a. -cos (4x +3) b. -(6x2+3) cos (2x3+3x-4) c. Cos (2x3+3x-4)<br />d. (6x3+3) cos (2x3+3)<br />
Let y = f(x)
f(x) = sin x
g(x) = (2x^2 + 3x - 4)
Use the chain rule.
We want y' = f' (g(x)) • g'(x).
y' = cos(2x^2 + 3x - 4) • (4x + 3)
Done.

Divide the fractions: 20 divided by 15/16 =
Final Answer:
[tex]\frac{64}{3}[/tex]
Step-by-step explanation:
20 ÷ [tex]\frac{15}{16}[/tex]
[tex]\frac{20}{1}[/tex] ÷ [tex]\frac{15}{16}[/tex]
(reciprocal method):
[tex]\frac{20}{1}[/tex] ÷ [tex]\frac{16}{15}[/tex]
(change the operation to multiplication)
[tex]\frac{20}{1}[/tex] × [tex]\frac{16}{15}[/tex] = [tex]\frac{320}{15\\}[/tex] (multiply, then reduce)
64/3 ⇒ 64/3
The value of x in the expression 20 divided by 15/16 will be 21.33 .
Given , 20 divided by 15/16
Division property:
The rules for division are:
(1) positive ÷ positive = positive
(2) positive ÷ negative = negative
(3) negative or ÷ negative = positive
Here both the numbers are positive. Apply rule 1.
20 divided by 15/16
[tex]\frac{20}{\frac{15}{16} }[/tex]
= [tex]\frac{20 \times 16}{15}[/tex]
= 21.33

Suppose you have 9 tubes of paint. How many distinct color groupings can you make with your paint?
9514 1404 393
Answer:
511
Step-by-step explanation:
Each tube can be included in the mix, or not. There are 2^9 = 512 possible subsets of a set of 9 objects, including the complete set and the empty set. The empty set will not make a color, so there are ...
2^9 - 1 = 511 distinct color groupings that can be made
__
The assumption in the above answer is that no tube color can be made by any combination of other tube colors.* We also assume that the choice of tubes is what makes a "color grouping", and that the colors within that grouping made by using different ratios of paint quantities are not counted separately.
