Write a function rule for the given situation. Give both the algebraic rule and the function rule.
Answer:
[tex]y=20x[/tex]
We know that the slope is 20 in this situation, as we can tell that 20 gallons are used every time the dishwasher is ran, therefore, everytime y increases by 1, x will increase by 20. Since the problem starts at the origin (0, 0), there is no y-intercept, so we don't have to worry about that.
if ∆ACB ≅ ∆DCE, ∠ABC=61°, ∠BCA=57° and ∠CDE=2x
ABC=CDE when ABC=61 then CDE=2X 2X=61 --> X=61/2=30.5
The value of x would be equal to 30.5
What are vertical angles?Each of the pairs of the opposite angles made by two intersecting lines are called vertical angles.
We are given that if ∆ACB ≅ ∆DCE,
∠ABC=61°,
∠BCA=57°
∠CDE=2x
Therefore,
ABC = CDE
then CDE = 2X
2X = 61
X=61/2
X =30.5
Hence, the value of x would be equal to 30.5

How many lumps of wax 2½ cm by 2 cm by 1 cm can be cut from a block 25 cm by 20 cm by 15 cm?
Step-by-step explanation:
first the theoretical maximum number :
the big block is 25cm×20cm×15cm.
so, the volume is 25×20×15 = 7500 cm³
we want to cut this note into pieces of 2.5cm×2cm×1cm with a volume of 2.5×2×1 = 5 cm³
so, we can get 7500/5 = 1500 such lumps out of the big block.
now, a quick check, if we can cut full pieces until the last bit, or if the shape of the big block will not allow us to fully cut it into the desired pieces, and we get some remains (too small to be lumps of the desired size and shape).
and we do this by checking, if each dimension of the big block can be divided by the dimensions of the small lumps without remainder (whole number results).
25 / 2.5 = 10, and no remainder here.
=> 10 cuts of 2.5 cm perpendicular to the length.
20 / 2 = 10, and no remainder here.
=> 10 cuts of 2cm perpendicular to the width.
15 / 1 = 15, and no remainder here.
=> 15 cuts of 1 cm perpendicular to the height.
so, yes, we can achieve the theoretical maximum number of 1500 lumps also in reality and cut the big block without remaining material into these small blocks.

John bought a recliner priced at $500, which was financed for $30 a month for 24 months. What is the total
cost for the recliner? How much is the finance charge?
Answer:
$720 total cost $220 finance
Step-by-step explanation:
30x 24= $720 total. 720-500= $220 is the finance charge.
:) hope this helped.
The total cost of the recliner is $720 thus the finance charge will be $220.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.
Multiplication = to multiply any two or more numbers or variables called multiplication.
Summation = addition of two or more numbers or variable
As per the given,
Price of recliner = $500
Financed for $30 for 24 months
Total cost = 30 x 24 = $720
Finance charge = $720 - $500 = $220
Hence "The total cost of the recliner is $720 thus the finance charge will be $220".

work out angle bxc. give a reason for each angle you work out
Answer:
∠ BXC = 70°
Step-by-step explanation:
∠ XBC and ∠ AXY are corresponding angles and are congruent, then
∠ XBC = 55°
Since XB = XC , then Δ XBC is isosceles and the 2 base angles are congruent.
∠ BXC = 180° - (55 + 55)° ← angle sum of triangle
∠ BXC = 180° - 110° = 70°

PLEASE HELP ME I REALLY NEED HELP
Answer:
mean; 7.55
median: 9
range: 8
mode: 10
standard deviation: 2.9 or 3
Step-by-step explanation:
a) mean: add all numbers and then divide them.. so:
3+9+10+5+8+5+9+11+10+3+10= 83
83 divided by 11 = 83/11 or 7 4/11
b) median: the middle number of the sequence but put in order first.. so:
smallest to largest: 3,3,5,5,8,9,9,10,10,10,11
so then middle number: 9
c) mode: most frequent (popular) figure/number.. so:
most frequent value: 10
d) range: difference between smallest number and largest number
so in this case: 11-3 = 8
e) positive direction

Use this graph of velocity vs. time for two objects to answer the question.
Which statement makes an accurate comparison of the motions for objects C and D?
A. Object C has an acceleration that is greater than the acceleration for D.
B. Objects C and D have different velocities but the same acceleration.
C. Object D has an acceleration that is greater than the acceleration for C.
D. Objects C and D have different accelerations but the same velocity throughout the motion.

Step-by-step explanation:
1.) Students are going to conduct an experiment to study the effect of a net force applied to an object on the object’s motion. In each trial of the experiment, the students will apply a net force on the object. They also need to take two other measurements. What are the other quantities they should measure in each trial of the experiment?
ANSWER: mass and acceleration
2.) Use the data table to answer the question. It shows the acceleration of a body when a net force is applied to it.

Enter your answer as a whole number or a fraction in simplest form in the box.
9514 1404 393
Answer:
1/4
Step-by-step explanation:
The slope can be found using the slope formula with the two left-most marked points:
m = (y2 -y1)/(x2 -x1)
m = (6 -5)/(0 -(-4)) = 1/4
The slope of the line is 1/4.
