Type the correct answer in each box. Use numerals instead of words. Consider the equation below. x/h+1=-2 The value of x in terms of h is ___. The value of x when h=4 is ___.
Answer:
x = -3h
x = -12
Step-by-step explanation:
Given equation is [tex]\frac{x}{h}+1=-2[/tex]
To find the value of x in terms of h we will solve the expression to isolate x on one side of the equation.
by subtracting 1 from both the sides of the equation,
[tex]\frac{x}{h}+1-1=-2-1[/tex]
[tex]\frac{x}{h}=-3[/tex]
Multiplying 'h' on both the sides of the equation,
[tex](\frac{x}{h})\times h = (-3)h[/tex]
x = -3h
If h = 4,
x = (-3)(4)
x = -12
Answer:
x = -3h

THE SEVEN APPLEWOMEN
Seven apple women, possessing respectively 20, 40, 60, 80, 100, 120, and 140
apples, went to market and sold all their apples at the same price, and each
received the same sum of money. What was the price?
Answer:
zero
Step-by-step explanation:
If the same sum is received for the sale of 20 apples at price p as is received for the sale of 140 apples at price p, then we must have ...
20p = 140p
120p = 0 . . . . . . subtract 20p
p = 0 . . . . . . . . . divide by 120
The price was zero.
Answer:
Price was 1 unit of money per each 7 apples and 3 units of money per each extra appleEach woman received 20 unit of moneyStep-by-step explanation:
This is the tricky one
I think 'The Seven Apple' is the hint. Let's see what the numbers have to do with 7:
20 = 7*2 + 640 = 7*5 + 560 = 7*8 + 480 = 7*11 + 3100 = 7*14 + 2120 = 7*17 + 1140 = 7*20 + 0Assume each '7 apples' sold for a fixed price x and each 'extra' apple sold for a different price y. Since all add up to make same amount, we get:
2x + 6y = 5x + 5y = ... = 20xLet x = 1, then we get y = 3
So we get the sold price:
20 apples cost: 2*1 + 6*3 = 2040 apples cost: 5*1 + 5*3 = 20...140 apples cost: 20*1 = 20So each apple woman got 20 units of money for their apples.
Price was 1 unit of money per each 7 and 3 units of money per each extra apple
Three Bears
In the land of Plentiful Honey, lived three bears: Papa
Bear, Mama Bear and Baby Bear. They had three pots
of honey: one large, one medium, and one small. One
day they found themselves carrying the pots of honey
down a path. Papa was carrying the medium pot, while
Mama was carrying the small pot, and Baby was
carrying the large pot. This was clearly inequitable and they decided to trade pots, so that
each was proportional to the size of the bear. It may seem there is a simple solution to their
dilemma, however, the rules for transferring pots in the land of Plentiful Honey are quite
complicated. They are:
a) Only one pot of honey can be passed at a time.
b) fa bear is holding two pots of honey, only the smaller pot may be transferred.
• A honey pot may not be transferred to a bear that is holding a smaller pot.
d) Pots may not be set on anything, such as the ground or a stump.
Diagram or explain the sequence of the transferring of honey pots, so that Papa Bear has the
large pot, Mama Bear the medium pot, and Baby Bear the small pot.
Answer:
m→B, s→P, m→M, s→M, l→P, s→B
Step-by-step explanation:
The initial state is ...
(Baby, Mama, Papa) = (Large, Small, Medium)
The large pot can only be transferred from someone holding only that pot, and only to someone holding no pots. The small pot can go anywhere any time.
Transfer the medium pot to Baby.
(B, M, P) = ({L, M}, S, –)
Transfer the small pot to Papa.
(B, M, P} = ({L, M} –, S)
Transfer the medium pot to Mama.
(B, M, P) = (L, M, S)
Transfer the small pot to Mama.
(B, M, P) = (L, {M, S}, –)
Transfer the large pot to Papa.
(B, M, P) = (–, {M, S}, L)
Transfer the small pot to Baby.
(B, M, P) = (S, M, L) . . . . . . desired end condition
The crosssectional areas of triangular prism and a night cylinder are congruent. The triangular prism has a helght of 5 units, and the right cylinder height of 3 unitsconclusion can be made from the given Information? The volume of the prism half the volume of the cylinder The volume of the prism is twice the volume of the cylinder The volume of the premis equal the volume of the cylinder. The volume of the is not equal to the volume of the cylinder
Answer:
The volume of the triangular prism is not equal to the volume of the cylinder
Step-by-step explanation:
Given that:
The cross sectional area of triangular prism and a night cylinder are congruent. The term 'congruent' means when two objects or shapes are placed above each other , they should both overlap exactly.
It was given that:
The triangular prism has a height of 5 units
and the right cylinder height of 3 units
The conclusion that can be drawn from this is that:
The volume of the triangular prism is not equal to the volume of the cylinder.
This is because, they do not occur in the same family. A triangular prism is a three - dimensional shape that has identical, parallel ends and parallel faces.
A triangular prism has two triangles at it ends and three rectangular faces.
The volume of the triangular prism is calculate by using the formula:
[tex]V= \dfrac{1}{2}\times b \times h\times l[/tex]
On the other hand, a cylinder is a shape with two circular ends and a curved surface.The two circular ends are congruent and both circular end posses the same cross section from one end to the other in the cylinder.
The volume of a cylinder is calculated by using the formula:
V = πr²h
Thus, we conclude that irrespective of the nature of their congruency, since the heights are different which will definitely affects their volume, the the volume of the triangular prism is not equal to the volume of the cylinder.

You and three friends go to the town carnival. You have a coupon for $20 off that will save your group money! If the total bill to get into the carnival was $100, how much does one regular price ticket cost?
Answer:
Regular price for 1 ticket = $30
Step-by-step explanation:
Given that a total of 4 people went to the carnival.
Total bill for the tickets = $100
Discount coupon used = $20
To find:
Cost of Regular price ticket = ?
Solution:
First of all, we need to find the regular price of tickets for 4 persons as if there was no coupon used.
If no coupon used, total bill of tickets = Total bill with coupon + Amount of coupon
Regular price for 4 tickets = 100 + 20 = $120
So, regular price for 1 ticket = Regular price of 4 tickets divided by 4
[tex]\text{Regular price for 1 ticket }= \$\dfrac{120}{4} = \$\bold{30}[/tex]
So, the answer is:
Regular price for 1 ticket = $30

Find the midpoint of the line segment joining the points R(3,2) and S(-5,5).
The x coordinates are 3 and -5. They add to 3+(-5) = -2
Cut this in half to get -2/2 = -1
The x coordinate of the midpoint is x = -1
-------------------
The y coordinates are 2 and 5. They add to 2+5 = 7.
Then we cut this in half to get 7/2 = 3.5
The y coordinate of the midpoint is y = 3.5
-------------------
Overall, the midpoint is (-1, 3.5)
Answer: (-1, 3.5) which is the same as (-1, 7/2)Write the equation for a parabola with a focus at (-2,5) and a directrix at y=3.
Answer:
(x+2)²=4(y-4)
or y=1/4 (x+2)²+4
Step-by-step explanation:
directrix y=3 and focus (-2,5) to find te equation of parabola we use the equation :
(x-h)²=4p(y-k)
vertex(h,k) : the vertex is half way between the focus and the directrix
y(vertex)=y(focus)+directrix/2
y=5+3/2 ⇒8/2=4
x is the same as the c of the focus =-2
vertex (-2,4)
to find the distance (p) which is the distance between the vertex and focus
p=5-4=1
substitute h=(-2), k=(4) and p=(1) in the equation : (x-h)²=4p(y-k)
(x-(-2)²=4(1)(y-4)
(x+2)²=4(y-4)

The formula for the area of a triangle is A = 12bh, where b is the base of the triangle and h is the height of the triangle. What is the length of the base if the area is 32 cm2 and the height is 4 cm?
Answer:
The base is 16 cm long.
Step-by-step explanation:
A = 1/2 * bh, we know that A = 32 and h = 4. We are solving for b so we can plug A = 32 and h = 4 into the equation to solve for b.
A = 1/2 * bh
32 = 1/2 * b * 4
32 = 2b
b = 16cm
Jayden is a waiter at a restaurant. Each day he works, Jayden will make a guaranteed wage of $30, however the additional amount that Jayden earns from tips depends on the number of tables he waits on that day. From past experience, Jayden noticed that he will get about $14 in tips for each table he waits on. How much would Jayden expect to earn in a day on which he waits on 16 tables? How much would Jayden expect to make in a day when waiting on
Answer:
$254
$30 + $14x
Step-by-step explanation:
Jayden:
Guaranteed wage= $30
Tips per table = $14
Number of tables = 16
Total revenue = fixed revenue + variable revenue
Fixed revenue= $30
Variable revenue change with quantity= $14 × number of tables Jayden waits on
Total earnings of Jayden for the day = $30 + $14(16)
= $30 + $224
= $254
When Jayden waits on x number of tables
Total earnings of Jayden for the day = $30 + $14(x)
= $30 + $14x
Where x = number of tables Jayden waits on
