Joanne is making punch. She uses 1/2 gallon of orange juice, 3 quarts of
lemonade, and 11/4 gallons of apple cider. How many quarts of punch will she
have all together? **Remember 4 quarts=1 gallon.
Your answer
Answer:
1/2 gallon=2 quarts plus 3 quarts so 5 quarts then 11/4 would be 11 quarts so 11+2+3=16 quarts
Step-by-step explanation:
If the 11/4 part is confusing you on how many quarts it actually is it simply means that for every 4 quarts you get a gallon and you have 11 quarts so you can also look at it as 2 3/4 gallons if that somehow clarifies it.

The hospital is 3.1 miles west of the fire station. What is the length of a straight line between the school and the hospital? Round to the nearest tenth. Enter your answer in the box.
miles
Answer:
Part A) The length of a straight line between the school and the Fire Station is [tex]4.6\ miles[/tex]
Part B) The length of a straight line between the school and the hospital is [tex]2.1\ miles[/tex]
Step-by-step explanation:
The complete question in the attached figure
Let
The positive x-coordinates ----> East
The positive y-coordinates ----> North
The negative x-coordinates ----> West
The negative y-coordinates ----> South
take the point A (0,0) as the Middle School (reference point)
Part A) we have
Town Hall is located 4.3 miles directly east of the Middle School
so
The coordinates of Town Hall are B(4.3,0)
The Fire Station is located 1.7 miles directly North of Town Hall
so
The coordinates of Fire Station are C(4.3,1.7)
What is the length of a straight line between the school and the Fire Station?
Remember that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
A(0,0) and C(4.3,1.7)
substitute
[tex]d=\sqrt{(1.7-0)^{2}+(4.3-0)^{2}}[/tex]
[tex]d=\sqrt{(1.7)^{2}+(4.3)^{2}}[/tex]
[tex]d=4.6\ miles[/tex]
Part B) we have that
The hospital is 3.1 miles west of the fire station
so
The coordinates of the hospital are D(4.3-3.1,1.7)
D(1.2,1.7)
What is the length of a straight line between the school and the hospital?
Remember that
the formula to calculate the distance between two points is equal to
[tex]d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}[/tex]
we have
A(0,0) and D(1.2,1.7)
substitute
[tex]d=\sqrt{(1.7-0)^{2}+(1.2-0)^{2}}[/tex]
[tex]d=\sqrt{(1.7)^{2}+(1.2)^{2}}[/tex]
[tex]d=2.1\ miles[/tex]

Which dimensions can create only one unique triangle?
three angles measuring 25 degrees, 65 degrees, and 90 degrees
three angles measuring 50 degrees, 50 degrees, and 50 degrees
three sides measuring 5 in., 12 in., and 14 in.
three sides measuring 4 ft, 8 ft, and 14 ft
Three sides measuring 5 in., 12 in., and 14 in.
Explanation:First of all, you need to know some facts about every triangle:
FIRST FACT:
If two sides of a triangle are [tex]a \ and \ b[/tex], then the third side must be less than [tex]a+b[/tex]. Why? because if its length is exactly [tex]a+b[/tex], then you can't build up a triangle, but you'll have a line segment. In other words:
[tex]a<b+c \\ \\ b<a+c \\ \\ c<a+b[/tex]
SECOND FACT:
The internal angles of any triangle add up to 180°. So if ∠A, ∠B and ∠C are the internal angles of a triangle, then:
[tex]\angle A +\angle B+ \angle C=180^{\circ}[/tex]
__________________________
So let's analyze each case:
Case 1. Three angles measuring 25 degrees, 65 degrees, and 90 degrees :
[tex]\angle A=25^{\circ} \\ \\ \angle B=65^{\circ} \\ \\ \angle C=90^{\circ} \\ \\ \\ \angle A +\angle B+ \angle C=25^{\circ}+65^{\circ}+90^{\circ}=185^{\circ} \neq 180^{\circ}[/tex]
The sum is greater than 180 degrees, so these angles can't form a triangle
Case 2. Three angles measuring 50 degrees, 50 degrees, and 50 degrees [tex]\angle A=50^{\circ} \\ \\ \angle B=50^{\circ} \\ \\ \angle C=50^{\circ} \\ \\ \\ \angle A +\angle B+ \angle C=50^{\circ}+50^{\circ}+50^{\circ}=150^{\circ} \neq 180^{\circ}[/tex]The sum is less than 180 degrees, so these angles can't form a triangle
Case 3. Three sides measuring 5 in., 12 in., and 14 in. [tex]a=5 \\ \\ b=12 \\ \\ c=14 \\ \\ \\ 5<12+14\rightarrow 5<26 \\ \\ 12<5+14 \rightarrow 12<19 \\ \\ 14<5+12 \rightarrow 14<17[/tex]The inequalities are true, so these sides form a triangle.
Case 4: Three sides measuring 4 ft, 8 ft, and 14 ft
[tex]a=4 \\ \\ b=8 \\ \\ c=14 \\ \\ \\ 4<8+14\rightarrow 4<22 \\ \\ 8<4+14 \rightarrow 8<18 \\ \\ 14<4+8 \rightarrow 14<12 \ NOT \ TRUE![/tex]
Since the third inequality is not true, then we can't form a triangle with these sides.
[tex]f(x)=16t^2+32t[/tex]The function f(x)=-16t^2+32t represents the height of a pumpkin t seconds after it is launched from a catapult. When does the pumpkin reach its maximum height? What is the maximum height of the pumpkin?
Answer:
- time = 1second
- maximum height = 16m
Step-by-step explanation:
Given the height of a pumpkin t seconds after it is launched from a catapult modelled by the equation
f(t)=-16t²+32t... (1)
The pumpkin reaches its maximum height when the velocity is zero.
Velocity = {d(f(x)}/dt = -32t+32
Since v = 0m/s (at maximum height)
-32t+32 = 0
-32t = -32
t = -32/-32
t = 1sec
The pumpkin reaches its maximum height after 1second.
Maximum height of the pumpkin is gotten by substituting t = 1sec into equation (1)
f(1) = -16(1)²+32(1)
f(1) = -16+32
f(1) = 16m
The maximum height of the pumpkin is 16m

A parabola can be represented by the equation x2 = -20y.
What are the coordinates of the focus of the parabola?
Answer:
[tex]\mathrm{Parabola\:focus\:given}\:x^2=-20y:\quad \left(0,\:-5\right)[/tex]
Step-by-step explanation:
Given the equation
[tex]x2 = -20y[/tex]
A parabola is the locus of points such that the distance to a point the focus equals the distance to a line the directrix.
[tex]4p\left(y-k\right)=\left(x-h\right)^2[/tex] is the standard equation for an up-down facing parabola with vertex at (h, k), and a focal length |p|.
so
[tex]x^2=-20y[/tex]
[tex]\mathrm{Switch\:sides}[/tex]
[tex]-20y=x^2[/tex]
[tex]\mathrm{Factor\:}4[/tex]
[tex]4\cdot \frac{-20}{4}y=x^2[/tex]
[tex]4\left(-5\right)y=x^2[/tex]
[tex]\mathrm{Rewrite\:as}[/tex]
[tex]4\left(-5\right)\left(y-0\right)=\left(x-0\right)^2[/tex]
[tex]\left(h,\:k\right)=\left(0,\:0\right),\:p=-5[/tex]
Parabola is symmetric around the y-axis and so the focus lies a distance\ p from the center (0, 0) along the y-axis.
[tex]\left(0,\:0+p\right)[/tex]
[tex]=\left(0,\:0+\left(-5\right)\right)[/tex]
[tex]\mathrm{Refine}[/tex]
[tex]\left(0,\:-5\right)[/tex]
Therefore,
[tex]\mathrm{Parabola\:focus\:given}\:x^2=-20y:\quad \left(0,\:-5\right)[/tex]
Please check the attached figure too.
The focus of the parabola given by the equation x2 = -20y is at the coordinates (0,-5). This is calculated by finding the value of 'p' in the standard form x2 = 4py.
The equation x2 = -20y is notably a form of the parabola equation known as standard form. This version of a parabola equation is defined in the form x2 = 4py (or it could be y2 = 4px), where p is the distance from the vertex to the focus (and also to the directrix).
In the given equation, x2 = -20y, comparing it with the standard form, we find 4p = -20 by observing the coefficient of 'y'. Solving for 'p', we get p = -20/4 = -5. This means the focus of the parabola is (0,-5), because for a parabola that opens downwards (since 'p' is negative), the focus is located at the coordinates (h, k-p), where 'h' and 'k' are the coordinates of the vertex (which is the origin (0,0) in this case).

Lashonda bought some books for $6 each and received a discount of $8 off of her total purchase. She spent $58 after the discount. How many books did she buy?
Write an equation that could be used to answer the question above. Let b represent the number of books. Solve for b
Answer:
6b - 8 = 58
6b = 66
b = 11
Each book costs $11.
Lashonda bought 11 books.
To solve this problem, we can set up an equation based on the information given. Let [tex]\( b \)[/tex] represent the number of books Lashonda bought. Each book costs $6, so the total cost before the discount is [tex]\( 6b \)[/tex]. Lashonda received a discount of $8 off of her total purchase, and she spent $58 after the discount. Therefore, the equation representing the total cost before the discount minus the discount equals the amount she spent is:
[tex]\[ 6b - 8 = 58 \][/tex]
Now, we solve for [tex]\( b \)[/tex]:
[tex]\[ 6b = 58 + 8 \][/tex]
[tex]\[ 6b = 66 \][/tex]
[tex]\[ b = \frac{66}{6} \][/tex]
[tex]\[ b = 11 \][/tex]
So, Lashonda bought 11 books.

Unless otherwise specified, the domain of a function f is assumed to be the set of all real numbers x for which f(x) is a real number.

The number of fish in a pond at time t years is modeled by the function N defined above, where f is a continuous function such that f(0)=80.
(a) Find limt→∞N(t). Explain the meaning of limt→∞N(t) in the context of the problem.
(b) Is the function N continuous at t=8 ? Justify your answer.
(c) The function N is continuous at t=6 . Is there a time t , for 0≤t≤6 , at which N(t)=250 ? Justify your answer.
Answer:
See Below
Step-by-step explanation:
The function is a piecewise function defined as:
[tex]N(t)=\left \{ {{25t+150} \ 0 \leq t \leq 6 \atop {\frac{200+80t}{2+0.05t} \ t \geq 8}} \right.[/tex]
a)
We need to find the limit of the function as t goes to infinity. This means what is the max value of fish in the pond given times goes to infinity (on an on).
We will take the 2nd part of the equation since t falls into that range, t is infinity, which is definitely greater than 8.
[tex]\lim_{t \to \infty} \frac{200+80t}{2+0.05t} \\\lim_{n \to \infty} \frac{80t}{0.05t}\\ \lim_{n \to \infty} \frac{80}{0.05} =1600[/tex]
This means the maximum number of fish at this pond is 1600, no matter how long it goes on.
b)
A function is continuous at a point if we have the limit and the functional value at that point same.
Functional value at t = 8 is (we use 2nd part of equation):
[tex]\frac{200+80t}{2+0.05t}\\\frac{200+80(8)}{2+0.05(8)}\\=350[/tex]
We do have a value and limit also goes to this as t approaches 8.
So, function is continuous at t = 8
c)
We want to find is there a "time" when the number of fishes in the pond is 250, during t from 0 to 6. We plug in 250 into N(t) and try to find t. Make sure to use the 1st part of the piece-wise function. Shown below:
[tex]N(t)=25t+150\\250=25t+150\\25t=250-150\\25t=100\\t=4[/tex]
The time is 4 years when the number of fishes in the pond is 250

One gallon of water weighs 8.34 pounds. How much does 6 gallons of water weigh? Show your work, including labeling your answer with the appropriate units of measure
Answer:
50.04 pounds
Step-by-step explanation:
If 1 gallon weighs 8.34 pounds,
all you have to do is multiply 8.34 by 6
to get what 6 gallons would weigh.
To determine the weight of 6 gallons of water, multiply the weight of one gallon (8.34 pounds) by 6. Thus, 6 gallons of water weigh 50.04 pounds.
To find out how much 6 gallons of water weigh, you simply need to multiply the weight of one gallon by the number of gallons.
Since we know that one gallon of water weighs 8.34 pounds, the calculation is as follows:
6 gallons × 8.34 pounds/gallon = 50.04 pounds.
Therefore, 6 gallons of water weigh 50.04 pounds.
