Elmer spent the day at the mall. First, he bought five rabbits for $10 each. Later, he bought four cupboards for $70 each. After that, he found a twenty dollar bill. Also, he returned one rabbit. Write the total change to Elmer's funds as an integer.
Answer:
-300
Step-by-step explanation:
Step 1: Find the amount Elmer's funds decreased after purchasing the rabbits:
Let x represent Elmer's funds.
Since Elmer bought five rabbits for $10 each, he lost $10 5 times.
x - (10 * 5)
x - 50
Thus, Elmer lost (spent) $50 for the 5 rabbits.
Step 2: Find the amount Elmer's funds decreased after purchasing the cupboards:
Since Elmer bought four cupboards for $70 each, he lost $70 4 times:
x - (50 + (70 * 4))
x - (50 + 280)
x - 330
Thus, after purchasing the rabbits and cupboards, Elmer lost $330.
Step 3: Find the amount Elmer's funds increased after finding the twenty-dollar bill:
Since Elmer found a twenty-dollar bill, he gained $20
x - (330 + 20)
x - 310
Step 4: Find the amount Elmer's funds increased after returning one rabbit:
Since Elmer returned one rabbit, he gained $10:
x - (310 + 10)
x - 300
Thus, Elmer's funds changed totally by -$300.
Putting all the information together, we have:
x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10
x - 50 - 280 + 30
x - 330 + 30
x - $300

5.A. Jonah filled a box and said its volume was 25 balls. Shandra filled the same box and said its volumen was 36 cubes. Explain how Jonah and Shandra could get different volumes for the same box. *
Answer:
the balls are larger, or don't pack as tightly
Step-by-step explanation:
The volume by either measure will depend on a couple of factors:
the volume of the unit used (ball or cube)the way the units can be packedIn a rectangular space, such as a box, it may be easier to pack cubes than balls. So, more cubes of the same volume would fit simply because they can be packed closer together.
We aren't told the volume of either the cube or the ball, and we're not told the extent to which the packing is optimized.
Fewer balls may fit because their packing is not as well optimized as that of the cubes, or because each has a larger volume than the cube being used.
let f(x)=4(1/4)^x+2. what is f(1)? answer in fraction form.
The value of the function, f(1) is 3. Note that the answer is already in its simplest form and cannot be expressed as a fraction.
First, let's start by understanding what the function f(x) represents. The function f(x) takes an input value x and returns an output value based on a specific rule. In this case, the rule is defined by the equation f(x) = 4(1/4)^x+2.
To find f(1), we need to substitute 1 in place of x in the equation for f(x). So, we get:
f(1) = 4(1/4)^1 + 2
Now, we need to simplify this expression. Recall that any number raised to the power of 1 is just that number itself. So, (1/4)^1 is just 1/4.
Therefore, we can simplify the expression as follows:
f(1) = 4(1/4) + 2
= 1 + 2

A) g(x) = 3f(x)
B) g(x) = f(x - 3)
C) g(x) = f(x) + 4
D) g(x) = 1/2 f(x)
Answer:
C) g(x) = f(x) + 4
Step-by-step explanation:
A vertical shift is where you shift, slide or translate the whole graph up or down (on a graph) The way this shows up in the equation is just a number tacked on to the end of the equation. A +anumber (like the +4 in the answer) slides the function UP four units. A
-anumber would slide the function DOWN instead.
As for the other answers:
A) the 3multiplied in front is a vertical STRETCH.
D) the 1/2 multiplied in front is a vertical shrink (smash)
B) The -3 in close tight with the x is a horizontal shift(slide, translate) It is a RIGHT shift. A +anumber would be a LEFT shift. Horizontal shift seem kind of backwards. + goes LEFT and - goes RIGHT.
Jeffrey went to the movies with his friends. The tickets cost $8.50 each for students and they spent $15.00 altogether at the concession stand. Their total was $49.00. How many people went to the movies?
Answer:
4 people
Step-by-step explanation:
Let's first write an equation.
We want to find the number of tickets t
The total was $49 so our equation will equal $49 and they spent $15 in snacks so on the other side of the eqaution we have to add $15, on the same side as the snacks we need to add in the cost of tickets, which is $8.50 multiplies by t, or the total number of tickets.
$49 = $8.50t + $15
Solve for t, first subtract $15 from both sides.
$49 - $15 = $8.50t
$34 = $8.50t Divide both sides by $8.50
$34/$8.50 = $8.50t/$8.50
$34/$8.50 = t
4 = t

How to calculate MLB magic number?
The formula to calculate the magic number in MLB is: Magic number = 163 - (number of wins by leading team) + (number of losses by trailing team) - 1.
The "magic number" in Major League Baseball (MLB) represents the combination of wins by the leading team and losses by the trailing team required for the leading team to clinch a playoff spot. To calculate the magic number, follow these steps:
1. Determine the total number of games in the season. In MLB, this is typically 162 games.
2. Subtract the number of games in the season from 163. For example, 163 - 162 = 1.
3. Subtract the number of wins by the leading team from 163. For example, if the leading team has 90 wins, 163 - 90 = 73.
4. Add the result from step 2 to the result from step 3. For example, 73 + 1 = 74.
5. Finally, subtract the number of losses by the trailing team from the result of step 4. For example, if the trailing team has 80 losses, 74 - 80 = -6. In this case, the magic number is zero, meaning that the leading team has already clinched a playoff spot.

(b) (i) If √/x-iy-a-ib. prove that √x+iy = a + ib.
Which can be simplified to:
√(x - iy) = √(x + iy) = a + ib
as required.
To solve this problemTo prove that √(x - iy) = a + ib, we can start by squaring both sides of the equation:
√(x - iy) = a + ib
√(x - iy)^2 = (a + ib)^2
x - iy = a^2 + 2iab - b^2
Since x and y are both real, we can equate the real and imaginary parts separately:
Real part: x = a^2 - b^2
Imaginary part: -y = 2ab
Solving for a and b in terms of x and y gives:
b = -y/(2a)
a^2 - b^2 = x
Substituting for b in the second equation gives:
a^2 - y^2/(4a^2) = x
Multiplying both sides by 4a^2 gives:
4a^4 - y^2 = 4a^2x
This is a quadratic equation in a^2. Solving for a^2 using the quadratic formula gives:
a^2 = (y^2 ± √(y^4 + 16x^2y^2))/(8)
Since we want a to be real, we take the positive square root:
a^2 = (y^2 + √(y^4 + 16x^2y^2))/(8)
Substituting this expression for a^2 into the equation a^2 - b^2 = x and using b = -y/(2a) gives:
(y^2 + √(y^4 + 16x^2y^2))/(8) - y^2/(4a^2) = x
Simplifying and solving for y gives:
y^2 = 4a^2x/(4a^2 - √(y^4 + 16x^2y^2))
Substituting this expression for y^2 into the equation for a^2 gives:
a^2 = (2x + √(x^2 + y^2))/2
Taking the square root of both sides gives:
a = √((2x + √(x^2 + y^2))/2)
Finally, substituting this expression for a into the equation for b gives:
b = -y/(2a) = -y/√((2x + √(x^2 + y^2))/2)
Therefore, we have shown that:
√(x - iy) = a + ib = √((2x + √(x^2 + y^2))/2) - i(y/√((2x + √(x^2 + y^2))/2))
which can be simplified to:
√(x - iy) = √(x + iy) = a + ib

limℎ→0(9+ℎ)−1−9−ℎFind solutions lim h→0 (9 + h)−1 − 9−1 h
The solution to lim h→0 (9 + h)−1 − 9−1 h is -1/9.
To find the solution to lim h→0 (9 + h)−1 − 9−1 h, we can simplify the expression first.
Starting with (9 + h)−1, we can use the formula for the difference of squares to get:
\((9 + h)-1 = (9 + h - 9) / ((9 + h)(9 - 9)) = h / (9h + h^2)\)
Substituting this back into the original expression gives:
\((9 + h)-1 -9-1 h = h / (9h + h^2) - 1 / 9h\)
We can combine the two fractions by finding a common denominator of 9h(9 + h), giving:
(9h - (9 + h)) / (9h(9 + h)) = -1 / (9 + h)
Now we can take the limit as h approaches 0:
lim h→0 (9 + h)−1 − 9−1 h = lim h→0 -1 / (9 + h) = -1 / 9
