Answer: t - 0.1t and 0.9t
Step-by-step explanation:
Let the original acreage be represented by t.
Since there was a sale which ended up reducing the acreage by 10%, the expression for the new acreage will be:
= t - (10% × t)
= t - (0.1 × t)
= t - 0.1t
= 0.9t
Therefore, the equivalent expressions will be "t - 0.1t" and 0.9t

A golf instructor offers 1-hour private lessons from 2 pm to 6 pm every Saturday afternoon. His hourly rate is $60. The instructor takes appointments during the weekdays. Recently, the instructor receives quite a few late cancellations in Saturday morning. He can do nothing given the short notice. Therefore, the instructor institutes an overbooking policy. In case a customer cannot be served, the instructor will give a $40 certificate (he buys it from the golf club) for a free round of golf. The number of no-shows can be 1, 2, 3, or 4, each with a probability of 0.25. How many reservations should the instructor take
Answer:
The answer is 8.
Step-by-step explanation:
He is guaranteed to make $240 between 2 and 6 pm every Saturday afternoon. For each time that both of the 2 customers booked for the same hour does not cancel, he earns only $20. Considering that the probability of cancellation is 25%, if he books 8 customers for the 4 hour period on Saturday afternoon, he is making an extra $80 which bumps up his total earnings to $320. If he accepts any booking after 8, each is going to cost him $40. So the total number of reservations he should take is 8.
I hope this answer helps.

Can someone help me with this?
Answer:
270 degrees
Step-by-step explanation:
hexagons have 5 sides and a five-sided shape has a sum of 540 degrees interior angle so 160+170+90 (because the square in the corner is a right angle which always equals 90 degrees) =420 so minus 420 from 540 to get 120+150 which equals 270 degrees. hope this helped.
3) Josie's collection of 39 coins includes twice as many nickels than quarters. If
the sum of the nickels and quarters is $4.55, How many quarters does Josie
have in her collection?
Answer:
13 quarters, 26 nickels.
Step-by-step explanation:
n will be number of nickels, q will be number of quarters, and we have 39 total coins
so n + q = 39 (number of nickels + number of quarters = 39 coins.
The problem also says there are twice as many nickels as quarters. so we can call the number of nickels n or we can call it 2q (2 times the number of quarters)
which means
n + q = 39
2q + q = 39
3q = 39
q = 13
and she has 2 times as many nickels as quarters... 2 x 13 = 26 nickels
LMK if you have questions.
If you want to double check the money,
n(0.05) + q(0.25) = 4.55 is the equation to use.
26(0.05) + 13(0.25) = 1.3 + 3.25 = $4.55

Why rotation, reflection, and translation are rigid motion?
Answer:
Reflections, translations, rotations, and combinations of these three transformations are "rigid transformations". ... A reflection is called a rigid transformation or isometry because the image is the same size and shape as the pre-image.

Need help with this geometry question
Answer:
UT = TW + WU = 27 + 27 = 54
WT = 27
ST = UT = 54
arc(XT) = angle XZT = 52 degrees
arc(ST) = angle SZT = 104
arc(US) = arc(ST) + arc(UT) = 104 + 104 = 208
I know it was super drawn out and there were probably quicker ways to do it, but I was justusing methods that came to mind rather than going for efficiency. let me know if any part is confusing.
Step-by-step explanation:
Let's start by just building on what we know
Since we know sv and vz can be made into the side of two triangles, SZV and TZV, we can use some similar triangle rules.
In SZV and TZV we know SZ = TZ since they are both radii, ZV = ZV because they are the same line and angle ZVS = angle ZVT since they are supplementary and one is 90 degrees. This allows us to solve and see if they are congruent or not. To do so we use the normal trig functions
sin(ZTV) = ZV/ZT = ZV/12
sin(ZSV) = ZV/SV = ZV/12
So the angles could be equal, but just to be sure lets look at all possible answers. with sine an angle x gives the same result as 180-x. Since both angles are acute thugh we know this can't be true so both angles are equal. Now we can say both triangles are congruent by AAS. Since they are congruent we can then confirm SV = VT.
In general you can say if a radii intersects a chord at a right angle then the intersection is a bisection. So now we know VT = 27
We can use similar methods to show UW = WT and if you made two triangles ZWT and ZWU you will see they are congruent. and since arc UT is 104 degrees that means angle UZT is 104 degrees. Since ZW bisects UT and the two triangles are congruent ZW also bisects angle UZT so UZW = TZW = 52 degrees.
Now we have 4 triangles, SZV, TZV, ZWT and ZWU and we know SZV and TZV are congruent and ZWT and ZWU are congruent. Now, if we can make one from each pair congruent we would knwo all four are congruent. Since TZV and ZWT share a side that's a good place to start. Looking at these two triangles we know those two sides are equal, and they both have a right angle. Also we know VZ = ZW fromt he instructions, so this is again a chance to check with trig.
Let's look at angle ZTW and ZTV.
sin(ZTW) = ZW/ZT = 27/ZT
sin(ZTV) = VZ/ZT = 27/ZT
Using the same reasoning as before we can say that the two angles are equal, so the two triangles are congruent. Now we can say a lot.
angle UZT = angle SZT = 104 degrees
angle SZV = angle VZT = angle TZW = angle WZU = 52
SV = VT = TW = WU = 27
Let's start solving.
UT = TW + WU = 27 + 27 = 54
WT = 27
ST = UT = 54
arc(XT) = angle XZT = 52 degrees
arc(ST) = angle SZT = 104
arc(US) = arc(ST) + arc(UT) = 104 + 104 = 208

y varies jointly as x and z. y = 75 when x = 5 and z = 5. Find y when x = 4 and z=6. y =
Answer:
y = 72
Step-by-step explanation:
Joint proportion is given by the expression;
y = kxz
Given the following values;
y = 75, x = 5 and z = 5
To find the constant, k;
75 = k*5*5
75 = 25k
k = 75/25
k = 3
Next, we find the value of y when x = 4 and z= 6
y = kxz
y = 3*4*6
y = 72
