Answer: B) 1/4
The greatest common factor of 4 and 16 is 4. This is the largest factor that goes into both numerator and denominator
Divide the numerator and denominator by the GCF
4/4 = 1
16/4 = 4
This means 4/16 reduces to 1/4
Thinking in reverse, you can multiply top and bottom of 1/4 by 4 to get 4/16.

Bradley wanted a blue gumball and a green gumball from a vending machine. There were 15 blue gumballs, 12 yellow gumballs, 2 green gumballs, and 16 purple gumballs. How many times would you expect to get a blue gumball or green gumball if a gumball was taken out 250 times?
Answer: Bradley would expect 94 times to get a blue or green gumball.
Step-by-step explanation:
Since we have given that
Number of blue gumballs = 15
Number of yellow gumballs = 12
Number of green gumballs = 2
Number of purple gumballs = 16
Total number of all gumballs = 45
Probability of getting either a blue gumball or green gumball be
[tex]\frac{15}{45}+\frac{2}{45}=\frac{17}{45}[/tex]
So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :
[tex]\frac{17}{45}\times 250=94.4[/tex]
Since we know that it must be less than 94.4.
So, the nearest smallest integer will be 94 times .
Hence, Bradley would expect 94 times to get a blue or green gumball.

There are 225 dozen cookies in the bakery. How many cookies are there?
Answer:
2700 cookies.
Step-by-step explanation:
A dozen is a grouping of twelve, that is a dozen = 12.
If there are 225 dozen cookies in the bakery, then there are
[tex]225\cdot 12=2700[/tex] cookies in the bakery.
there are 2700 cookies in total
Since there are 225 dozen cookies in the bakery, we need to determine the total number of cookies.
To convert dozen to individual units, we multiply the number of dozens ( 225 ) by 12, as there are 12 cookies in each dozen :
225 dozen * 12 cookies / dozen = 2700 cookies
Therefore, there are 2700 cookies in total. By multiplying the number of dozens by 12, we account for the fact that each dozen contains 12 cookies. This calculation allows us to determine the precise quantity of cookies in the bakery.

in the figure above CD is the perpendicular bisector of AB. three students explained how they proved ADC is congruent to BDC
who's explanation is incorrect??
Answer:
All explanations are correct
Step-by-step explanation:
In triangle ABC, CD is the perpendicular bisector of AB, thus using ΔADC and ΔBDC,
AC=BC ( Since CD is perpendicular to AB, therefore C is equidistant from both A and B)
∠ADC=∠BDC=90°(CD perpendicular AB)
CD=CD( Reflexive property)
therefore, by SAS rule of congruency,
ΔADC≅ ΔBDC,
Also, In the same triangles, AC=BC ( Since CD is perpendicular to AB, therefore C is equidistant from both A and B)
CD=CD( Reflexive property)
AD=BD (D is the midpoint and divides AB into two equal halves)
Thus, by SSS rule of congruency,
ΔADC≅ ΔBDC,
Thus, all the three explanations are correct.
In the given case, we can conclude that All explanations are correct
In triangle ABC, let CD be the perpendicular bisector of AB. We can use the properties of triangles to demonstrate that ΔADC is congruent to ΔBDC.
AC=BC: This holds true because CD is perpendicular to AB, making point C equidistant from both A and B.
∠ADC=∠BDC=90°: Since CD is perpendicular to AB, both angles ADC and BDC are right angles.
CD=CD: This is a reflexive property, stating that any line segment is equal to itself.
By applying the SAS (Side-Angle-Side) rule of congruency using the above properties, we can conclude that ΔADC is congruent to ΔBDC.
Furthermore, we can establish that in these congruent triangles:
AC=BC (since C is equidistant from A and B due to CD being perpendicular to AB).
CD=CD (reflexive property).
AD=BD (as D is the midpoint of AB).
Hence, using the SSS (Side-Side-Side) rule of congruency, we can also conclude that ΔADC is congruent to ΔBDC.
Therefore, all three explanations correctly demonstrate the congruence of these triangles.

please help, i am loosing a braincell each day
Answer:
Volume of tray =[tex]4x^{3} -60x^{2} +216x[/tex]
Step-by-step explanation:
The Dimensions of rectangular cardboard is given by 12 inches by 18 inches
Length of the rectangular cardboard = 18 inches
Width of the rectangular cardboard = 12 inches
if the square of sides x inches is cut from each corner of the rectangular cardboard and folded to make a tray, then we have
Length of the tray = length of cardboard - 2 (side of the square )
= [tex]18-2x[/tex]
Width of the tray = width of cardboard - 2( side of square)
= [tex]12-2x[/tex]
height of tray = sides of square
= x
volume of tray = Length × width × height
Volume of tray = [tex]x(18-2x)(12-2x)[/tex]
first we multiply (12-2x) and (18-2x)
Volume of tray =[tex]x(18(12-2x)-2x(12-2x))\\[/tex]
=[tex]x(216-36x-24x+4x^{2})[/tex]
=[tex]x(4x^{2}-60x+ 216)[/tex]
=[tex]4x^{3} -60x^{2} +216x[/tex]
Hence the volume of tray =[tex]4x^{3} -60x^{2} +216x[/tex]
The volume of the Tray is given by the equation [tex]4x^3-60x^2+216x[/tex] and this can be determined by using the given data.

Brian rented a book from the book shop.The shop charges $2 for the first day and $3 from the second day onwards.Brian took more then 2 days to return the book and he paid $35 while returning the book.How many days did he keep the book with him?
Brian rented the book for 12 days.
Brian rented a book with the condition that the shop charges $2 for the first day and $3 from the second day onwards. He paid a total of $35 upon returning the book. To determine how many days he kept the book, we must calculate the cost for each day and subtract the initial $2 from the total amount paid.
Steps to Calculate the Number of Days:
Subtract the first day's charge from the total amount: $35 - $2 = $33.Divide the remaining amount by the daily charge starting from the second day: $33 / $3 = 11 days.Add the first day to the result: 11 days + 1 day = 12 days.Therefore, Brian kept the book with him for 12 days.

Step-by-step explanation:
Common ratio of a geometric sequence is the ratio of a term and its previous term of the sequence.
Thus, the common ratio of the sequence A: 160,40,10,2.5,...
[tex]r_1=\frac{40}{160}=\frac{1}{4}[/tex]
The common ratio of the sequence B: -21,63,-189,567,...

The common ratio of the sequence C : 8,12,18,27,....
[tex]r_3=\frac{12}{8}=\frac{3}{2}[/tex]
Since, -3 < [tex]\frac{1}{4}[/tex] < [tex]\frac{3}{2}[/tex]
Thus,
[tex]r_2 < r_1 < r_3[/tex]
Hence, the order the sequences from least common ratio to the greatest common ratio is,

Jay is 4 years younger than three times Tamia's age. Jay is 20 years old. How old is Tamia?
Final answer:
To find Tamia's age, an equation was set up based on the relationship between Jay and Tamia's ages. Jay is 20 years old and 4 years younger than three times Tamia's age. Solving the equation shows that Tamia is 8 years old.
Explanation:
Jay is 4 years younger than three times Tamia's age. Given that Jay is 20 years old, we can use this information to find out how old Tamia is. Let's denote Tamia's age as T. The relationship between their ages can be represented by the equation: Jay's age = 3 × Tamia's age - 4. Since Jay's age is 20, we can substitute this into the equation, giving us 20 = 3T - 4.
To solve for T, we first add 4 to both sides of the equation, which gives us 24 = 3T. Next, we divide both sides by 3 to find Tamia's age, resulting in T = 8. Therefore, Tamia is 8 years old.
This problem was solved by setting up an equation based on the relationship described between Jay and Tamia's ages, then using basic algebraic steps to solve for Tamia's age.
find the area of washers whose external and internal diameter are 1.2m and 0.9m
Answer:
0.49 m²
Step-by-step explanation:
The area (A) is calculated using A = πr² ( r is the radius )
A = external area - internal area
external radius = [tex]\frac{1.2}{2}[/tex] = 0.6
internal radius = [tex]\frac{0.9}{2}[/tex] = 0.45
A = π(0.6² - 0.45²)
= π(0.36 - 0.2025) = 0.1575π ≈ 0.49 m²
Final answer:
The area of the washers is 0.49m².
Explanation:
To find the area of the washers, we need to find the areas of the outer and inner circles and then subtract the smaller area from the larger one. The area of a circle is given by the formula A = πr², where r is the radius of the circle. In this case, the external diameter is 1.2m, so the radius is half of that, or 0.6m. The area of the outer circle is A₁ = π(0.6)² = 1.13m². Similarly, the radius of the inner circle is 0.45m, and the area of the inner circle is A₂ = π(0.45)² = 0.64m². Finally, the area of the washer is the difference between the two areas: A = A₁ - A₂ = 1.13m² - 0.64m² = 0.49m².

(4,-8)
(-4,8)
(-4,-8)
Answer:
The correct option is 1. The image of (2,4) is (4,-8).
Step-by-step explanation:
The given rule is
[tex]R_x{\circ}D_{o,2}:(2,4)[/tex]
The transformations perform from right to left. [tex]D_{o,2}[/tex] means dilation with scale factor 2 and center of dilation is origin.
The given rule defines the dilation with scale factor 2 and center of dilation is origin followed by reflection across x-axis.
If a figure dilated by scale factor k and the center of dilation is origin, then
[tex](x,y)\rightarrow (kx,ky)[/tex]
The scale factor is 2,
[tex](x,y)\rightarrow (2x,2y)[/tex]
[tex](2,4)\rightarrow (4,8)[/tex]
If a figure reflected across x-axis, then x-coordinate remains the same but the sign of y-coordinate is changed.
[tex](x,y)\rightarrow (x,-y)[/tex]
[tex](4,8)\rightarrow (4,-8)[/tex]
Therefore image of (2,4) is (4,-8) and option 1 is correct.

[1 mile = 1.6 km]
a- 0.2
b- 0.5
c- 0.8
d- 1.4
Answer:
We have the following given
mileage = 70 miles per gallon
distance = 60 km
Required: amount of fuel in gallons
First, we must convert the distance to miles, so
60 km (1 mi/1.6 km) = 37.5 mi
So, the amount of fuel is
37.5 mi / (70 mi/gal) = 0.54 gallon
Answer:
B
Step-by-step explanation:
70 miles * [1.6 km/mile] = 112 km
Notice when you multiply by km/mile by miles the miles cancel out.
1 gallon will get 112 km
x gallon will get 60 km
1/x = 112/60 cross multiply1 * 60 = 112 * x divide by 11260/112 = x switchx = 60/112 Do the divisionx = 0.54 Which rounds to 0.5Mrs Wong is going on a trip.
