Step-by-step explanation:
X+X=25-13
Answer:
114
Step-by-step explanation:
Let x+y=25
Let x-y=13
Let's isolate one variable
x-y=13 can be re-written as x=13+y
Now that we isolated x we can replace it in the other equation
(x)+y=25
(13+y) +y=25
13 +2y=25
-13 -13
2y=12
12/2=6
We know that y=6
Let's replace y with 6 to find x
x+(y)=25
x+6=25
-6 -6
x=19
The goal of this problem was to find the product of x and y so now we have to multiply them
19*6=114
Your answer is 114

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

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

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.

see a) for L:P
c) 14W = 342.44
W = 24.46

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°
