well...
if all three bags cost $4,000 then you'll need $3,700.
but if one bag costs $4,000 then that'll equal to $12,000 which then you'll need $11,700.
i might've misundestood your question so please let me know if this is correct!
A timer is started as a ball is dropped from a certain height and its velocity measured. After 0 seconds, the ball is falling at 0 feet per second. After 2 seconds, the ball is falling at 64 feet. After 3 seconds, the ball is traveling at 96 feet and after 4 second the ball is traveling 128. Is this a proportional relationship?
Answer:
yes
because the descent of the ball is 32m per second
Step-by-step explanation:
To determine if the relationship is proportional, determine the descent of the ball per second
after 2 seconds = 64 / 2 = 32
after3 seconds = 96/3 = 32
after 4 seconds = 128 / 4 = 32
the relationship is proportional

On a certain hot summer's day, 554 people used the public swimming pool. The
daily prices are $1.75 for children and $2.50 for adults. The receipts for admission totaled $1097.00.
How many children and how many adults swam at the public pool that day?
Answer:
Children= 384 Adults= 170
Step-by-step explanation:
First, write a system of algebraic equations:
[tex]1.75x+2.50y=1097[/tex]
[tex]x+y=554[/tex]
Second, use linear combination to eliminate one variable (I will eliminate x, or children.)
[tex]1.75x+2.50y=1097[/tex]
[tex]-1.75(x+y=554)[/tex]
[tex]1.75x+2.50y=1097[/tex]
[tex]-1.75x+-1.75y=-969.5[/tex]
[tex]0.75y=127.5[/tex]
Divide both sides by 0.75
[tex]0.75y=127.5[/tex]
[tex]/0.75[/tex] [tex]/0.75[/tex]
[tex]y=170[/tex], there are 170 adults
Now, plug in 170 for [tex]x+y=554[/tex]
[tex]x+170=554[/tex]
Subtract 170 from both sides
[tex]x+170=554[/tex]
[tex]-170[/tex] [tex]-170[/tex]
[tex]x=384[/tex], there are 384 kids.
Hope this helps!!!
Answer:
384 children and 170 adults
Step-by-step explanation:
if x is children and y is adults
1.75x+2.5y=1097
x+y=554
1.75x=1097-2.5y
x=554-y
1.75x=1097-2.5y
1.75x=1.75(554-y)
1097-2.5y=969.5-1.75y
1097-969.5=2.5y-1.75y
127.5=0.75y
127.5/0.75=y
170=y
x+y=554
x=554-y
x=554-170
x=384
to prove these are correct just do 1.75(384)+2.5(170) and see if it equals 1097, and do 384+170 to see if its the amount of people
1.75(384)+2.5(170)
672+425
1097
384+170=554

Solve for x. Exclude any extraneous solutions:
4/3x+5/4=3/x
Answer:
x = 4/3
Step-by-step explanation:
[tex]\frac{4}{3x} + \frac{5}{4} = \frac{3}{x}[/tex]
take lcm of the denominator
lcm = 12x
[tex]\frac{4*4 +5*3x}{12x} = \frac{3}{x}[/tex]
[tex]\frac{16+15x}{12x} = \frac{3}{x}[/tex]
do cross multiplication
x(16 + 15x) = 3*12x
16x + 15x^2 = 36x
15x^2 = 36x - 16x
15x^2 = 20x
x^2 = 20x /15
x*x = 4x/3
x = 4x/3/x
x = 4x/3 *1/x
x = 4x/3x
x = 4/3
10. Use the vertical line test to determine if the graph below
represents a function. If it is not a function, tell where the
vertical line test fails.
The graph is a function. When drawing a vertical line, there will be two circumstances:
The line intersects only one point on a graph. The line intersects more than one point on a graph ( POI > 1 )For the first circumstance, the graph that has only one intersect with a line - it is a function. For the second circumstance, the graph cannot be a function as it gives more than one y-value for a single x-value.
The conclusion is that if a line only has one intersect on a graph then it is a function. Otherwise, not a function but a relation instead. All functions are relations, but not all relations can be functions.
Answer
The graph passes the vertical line test and is a function.. has endpoints B(5, 9) and C(–4, –3). Find the coordinates of the midpoint of . (0.5, 1.5) (1, 3) (0.5, 3) (1, 6)
Answer:
(0.5,3)
Step-by-step explanation:
Hi there!
We are given a line that has the endpoints of (5,9) and (-4,-3); we need to find the midpoint of the line.
The midpoint formula is given as ([tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2}}{2}[/tex]), where [tex]x_{1}[/tex], [tex]x_{2}[/tex], [tex]y_{1}[/tex], and [tex]y_{2}[/tex] are values of coordinate points
to avoid any confusion, we can label the values of the coordinates and then substitute them into the formula to find the midpoint
[tex]x_{1}[/tex]=5
[tex]y_{1}[/tex]=9
[tex]x_{2}[/tex]=-4
[tex]y_{2}[/tex]=-3
now substitute into the formula
so to find the value x in the midpoint, we'll use this part of the formula: [tex]\frac{x_{1}+x_{2} }{2}[/tex]
substitute 5 and -4 into the formula
[tex]\frac{5+-4}{2}[/tex]
do the addition on the numerator
[tex]\frac{1}{2}[/tex] or 0.5
now let's find the value of y in the midpoint. we'll use this part of the formula: [tex]\frac{y_{1}+y_{2}}{2}[/tex]
substitute 9 and -3 into the formula
[tex]\frac{9+-3}{2}[/tex]
do the addition on the numerator
[tex]\frac{6}{2}[/tex] or 3
Therefore the midpoint is (0.5,3)
Hope this helps! :)

Consider function h. Complete the statements describing the y-values of function h.
1. The end behavior of function h is described by (an oblique, no, or absolute) asymptote.
2. The range of function h is all y-values (less than or equal to 4,1,-4, or 0) and (greater than 1, 0, -4, or 4)
Answer:
1) The end behavior of function [tex]h[/tex] is described by an absolute (horizontal) asymptote.
2) The range of function [tex]h[/tex] is all y-values less than or equal to 0 and greater than 1.
Step-by-step explanation:
1) The end behavior of the function is defined by a horizontal asymptote, that is the values of [tex]y[/tex] when [tex]x[/tex] tends to [tex]\pm \infty[/tex]. Answer: The end behavior of function [tex]h[/tex] is described by an absolute (horizontal) asymptote.
2) The range of the function is the set of values of [tex]y[/tex] associated with the function. The existence of two vertical asymptotes give the following solution for the range: [tex]Ran \{h\} = (-\infty, 0] \,\cup\,(1, +\infty)[/tex] Answer: The range of function [tex]h[/tex] is all y-values less than or equal to 0 and greater than 1.
In the figure above, what is the value of a + b + c + d + e + f?
Answer:
a+b+c+d+e+f = 360º
Step-by-step explanation:
Each side of the outer triangle
is a straight line segment which is 180º
Since there are three sides
180 * 3 = 540º
therefor a+b+c+d+e+f + inside triangle = 540
The angles of the inside triangle total 180º
a+b+c+d+e+f = 540 - 180
a+b+c+d+e+f = 360º

Ryan spent $3.25 on lunch every day, Monday through Friday. If he had $20 at the start of the week, how much money did he have left after Friday
Monday through Friday is 5 days.
Multiply the cost of lunch by number of days:
3.25 x 5 = $16.25
Subtract the total he spent on lunch from what he started with for money:
20 - 16.25 = 3.75
He had $3.75 left.
Answer:
He had $3.75 dollars left.
Step-by-step explanation:
He was spending launch money for five days so:
3.25*5 is the total amount of money he spent that week.
The amount of Mooney he had minus the amount of money he spent is the amount of money left.
20-3.25*5= 3.75
Jason rolls a fair number cube labeled 1 through 6 and then he flips a coin what is the probability that he rolls a 3 and flips a head
There are 6 numbers on the cube.
The probability of getting a 3 would be 1 out of 6, 1/6
The probability of getting heads on a coin toss is 1/2
The probability of getting both a 3 and a head = 1/6 x 1/2 = 1/12

Keegan deposited $700 into his bank account. After one year, his bank account balance was $761.60. What interest rate did he earn?
Answer:
8.8%
Step-by-step explanation:
We first divide the new amount by the original and close it with brackets.
Our one year will be shown as 1/1 as an indices
(761.60/700)^1/1
= 1.088
We then convert it to 0.088 and times it by 100.
0.088×100= 8.8% Compound interest rate.
This is correct as:
700×1.088= 761.6

Sienna is determining the solution 6b + 12 = 102 A:15 B:17 C:90 D:102
In triangle ABC, b = 600, ∠B = 11°, and ∠C = 75°. Find a.
Answer:
Step-by-step explanation:
We could use the Law of Sines if we only knew what angle A was. It just so happens that by the Triangle Angle-Sum Theorem, angle A is equal to
180 - B - C. Therefore,
angle A = 180 - 11 - 75 so
angle A = 94. And the Law of Sines is
[tex]\frac{sin94}{a}=\frac{sin11}{600}[/tex] and cross multiply to get
600sin94 = asin11 and solve for a:
[tex]a=\frac{600sin94}{sin11}[/tex] gives you that
a = 3136.85

A rectangle has an area of 161.2m2.
One of the sides is 5.2m in length.
Work out the perimeter of the rectangle
Answer:
72.4 m
Step-by-step explanation:
The area of a triangle is
A = l*w
161.2 = 5.2 *w
Divide each side by 5.2
161.2/5.2 = w
31 =w
Now find the perimeter
P =2 (l+w)
P =2 ( 5.2+31)
P =2( 36.2)
P =72.4
