Answer:
you pay 15.3 dollars
Step-by-step explanation:
15 times 0.1 is 1.5
15 times 0.08 is 1.2
15-1.5+1.2=15.3
Given P(A)=0.8P(A)=0.8, P(B)=0.62P(B)=0.62 and P(A union B)=0.874P(A∪B)=0.874, find the value of P(A unionB)P(A∩B), rounding to the nearest thousandth, if necessary.
Use the inclusion/exclusion principle:
P(A ∩ B) = P(A) + P(B) - P(A ∪ B)
So
P(A ∩ B) = 0.8 + 0.62 - 0.874 = 0.546
A bakery sold apple pies for $12 and blueberry pies for $14 on Saturday sold a total of 41 pies and collected a total of $536 how many apple pies did you sell and how many blueberry pies do they sell
Answer:
22 blueberry pies and 19 apple pies.
Step-by-step explanation:
This can be solved using a system of equations. Your equation for amount of pies sold is x + y = 41, with x representing apple pies and y representing blueberry pies, and 41 being the total amount of pies sold. The other equation is for the amount of dollars earned from selling the pies, which is:
12x + 14y = 536 $12 per apple pie, $14 per blueberry pie, and a total of $536.
Let's first solve for x. The new equation would be x = 41 - y. Now, we plug this equation into the second equation.
12(41 - y) + 14y = 536 Here we substituted x for the equation we made.
429 - 12y +14y = 536
-12y +14y = 44 Here we moved the 429 to the other side by subtracting it from the left and right.
2y = 44
y = 22. Now we know that there was a total of 22 blueberry pies sold. Now we plug 22 pies back into the very first equation to find x, the amount of apple pies.
x + 22 = 41
x = 19. Now we know there was a total of 19 apple pies sold.

Catherine has 6 gallons of milk and uses 26/5 gallons to make cookies. What fraction of a gallon does she have left?
Answer:
4/5 gallons left
Step-by-step explanation:
make sure before subtracting that it has the same denominator.
Answer:2
Step-by-step explanation:
There are 256 Tsp in a gallon...so 1 Tsp = 1/256 gal. If one batch of cookies calls for 3 Tsp of milk, 5 batches will require 15 Tsp. So..... 15 / 256 ...

Help please. I need this ASAP
Answer:
B
Step-by-step explanation:
Expanding the factors using FOIL
A
(x - 3)(x + 4)
= x² + 4x - 3x - 12
= x² + x - 12 ← a trinomial
B
(x + 3)(x - 3)
= x² - 3x + 3x - 9
= x² - 9 ← a binomial
C
(x - 3)² = (x - 3)(x - 3) = x² - 6x + 9 ← a trinomial

Max has a Starbucks' gift card for $50. HIs favorite drink is the S'mores Frappuccino. Each drink costs $4.25. How many frappuccinos can Max purchase with his gift card? Write an inequality to represent the number of frappuccinos Max can purchase. How many frappuccinos can Max purchase with his gift card?
Answer:
4.25x ≤ 50
Number of drink = 11
Step-by-step explanation:
Given:
Amount of gift card = $50
Each drink cost = $4.25
Find:
Number of drink
Computation:
Assume;
Number of drink = x
So,
4.25x ≤ 50
x ≤ 11.76
so,
Number of drink = 11

proportions please help!
Answer:
[tex]\huge\boxed{x=-12}[/tex]
Step-by-step explanation:
In order to solve for this proportion, it’s important to note that this is basically just an equation. Like any other, our goal is to isolate x on one side.
Since we have two fractions, we can multiply both sides by both the denominators (x-3 and x-9). Since one will cancel out the other, we can just multiply both sides by the opposite denominator.
[tex]5(x-9)=7(x-3)\\\\5x-45=7x-21[/tex]
Now we can solve for x.
Subtract 5x from both sides:
[tex]-45=2x-21[/tex]
Add 21 to both sides:
[tex]-24=2x[/tex]
Divide both sides by 2:
[tex]x = -12[/tex]
Hope this helped!
Answer:
[tex]x= -12[/tex]
Step-by-step explanation:
Step 1: Write equation
[tex]\frac{5}{x-3} =\frac{7}{x-9}[/tex]
Step 2: Solve for x
Cross multiply: [tex]5(x-9)=7(x-3)[/tex]Distribute: [tex]5x-45=7x-21[/tex]Subtract 5x on both sides: [tex]-45=2x-21[/tex]Add 21 to both sides: [tex]-24=2x[/tex]Divide both sides by 2: [tex]-12=x[/tex]Rewrite: [tex]x= -12[/tex]Step 3: Check
Plug in x to verify it's a solution.
[tex]\frac{5}{-12-3} =\frac{7}{-12-9}[/tex]
[tex]\frac{5}{-15} =\frac{7}{-21}[/tex]
[tex]\frac{-1}{3} =\frac{-1}{3}[/tex]
