Torrance is shopping for a school party. His donation to the party is snack bags and juice boxes. Snack bags come in packages of 12, and juice boxes come in a package of 10. What is the fewest number of packages of each product Torrance must purchase so that he has the same number of snack bags and juice boxes? Use paper to show what you know about the least common multiple to support your answer. Enter your answers in the boxes. Torrance must purchase packages of snack bags and packages of juice boxes to have the same number of each
Answer:
Torrance must purchase 5 packages of snack bags and 6 packages of juice boxes.
Step-by-step explanation:
Given that:
Snack bags come in packages of 12.
Juice bags come in packages of 10.
To find:
Fewest number of packages of each product so that there are same number of snack bags and juice boxes.
Solution:
Number of snack bags when 1 package is bought = 12
Number of snack bags when 2 package is bought = 24
Number of snack bags when 3 package is bought = 36
Number of snack bags when 4 package is bought = 48
Number of snack bags when 5 package is bought = 60
Number of snack bags when 6 package is bought = 72
Number of juice bags when 1 package is bought = 10
Number of juice bags when 2 package is bought = 20
Number of juice bags when 3 package is bought = 30
Number of juice bags when 4 package is bought = 40
Number of juice bags when 5 package is bought = 50
Number of juice bags when 6 package is bought = 60
Number of juice bags when 7 package is bought = 70
We can see that when 5 packages of snack bags are bought and 6 packages of juice bags are bought, 60 bags of each are bought.
This can be found by finding the LCM as well.
LCM of 10 and 12 is 60.
It means we need to buy 60 bags of each item.
And we can easily find the number of packages for each.
Number of packages of snack bags to be bought = [tex]\frac{60}{12} =5[/tex]
Number of packages of juice bags to be bought = [tex]\frac{60}{10} = 6[/tex]
Torrance must purchase 5 packages of snack bags and 6 packages of juice boxes.

Answer:
The average speed of the athlete for the entire competition is approximately 21.23 km/hr
Step-by-step explanation:
The given parameters of the athlete performance in the triathlon are;
The length the athlete swims = 750 m = 0.75 km
The time the athletes spends swimming = 15 minutes = 0.25 hours
The speed with which the athlete cycles = 40 km/hr.
The time the athletes spends while cycling = 30 minutes = 0.5 hours
The distance the athlete ran = 5 km
The average speed with which the athlete ran = 3 m/s = 10.8 km/hr.
The formula for average speed, s is Average speed = Total distance/(Total time)
The distance, ∑d, the athlete covered in the entire competition is given as follows;
∑d = 0.75 km + 0.5 hr. × 40 km/hr. + 5 km = 0.75 km + 20 km + 5 km = 25.75 km
The distance, ∑t, the athlete spends in the entire competition is given as follows;
∑t = 0.25 hr. + 0.5 hr. + 5 km/(10.8 km/hr.) = 0.25 hr. + 0.5 hr. + 0.463 hr. ≈ 1.213 hr.;
Therefore;
The average speed of the athlete for the entire competition, s = ∑d/∑t = 25.75 km/(1.213 hr.) ≈ 21.23 km/hr.

Equations and inequalities fall under the umbrella of algebra. Algebra is the category of math where letters, like x and y, are used to represent numbers. These letters are called variables, and the goal of equations and inequalities is to find the value of the variable. An equation is a statement that two expressions or values are equal, shown by an equal sign, which looks like this: =. An inequality is a statement that two expressions or values are not equal, shown by an inequality sign. The four inequality signs look like this: > (“greater than”), 437

Lou's car had 6.6 gallons in the 16- gallon tank on the coldest day of the year . Lou filled the tank with gas that cost 3.70 per gallon how much money did lou spend
Answer: $33.48
Step-by-step explanation:
Given that:
Capacity of car tank =. 16 gallons
Gallons of already filled = 6.6 gallons
Amount left of tank capacity = 16 - 6.7
Amount left of tank capacity = 9.3 gallons
Cost of gas per gallon = $3.60
Hence, amount spent in gas will be
Amount left of tank capacity * cost per gallon of gas
= 9.3 gallons * $3.60
= $33.48
Total amount spent on gas = $33.48

A pentagon will be dilated on a coordinate grid to create a larger pentagon. The pentagon is dilated using the origin as the center of the dilation. What rule could represent this dilation?
A. (x, y)→(x+3, y−3)
B. (x, y)→(x−2, y+2)
C. (x, y)→(12x, 12y)
D. (x, y)→(52x, 52y)
Answer:
a
Step-by-step explanation:
The pentagon is dilated 3 units to the left and 3 units vertically down and the rule is ( x , y ) → ( x + 3 , y - 3 )
What is Dilation?Resizing an item uses a transition called Dilation. Dilation is used to enlarge or contract the items. The result of this transformation is an image with the same shape as the original. However, there is a variation in the shape's size. Dilation transformations ensure that the shape will stay the same and that corresponding angles will be congruent
Given data ,
Let the pentagon be represented as A
Now , the dilated pentagon is represented as A'
Now , the center of dilation is the origin O ( 0 , 0 )
where it is dilated 3 units to the left
So , the x coordinate is changed to x + 3
And , dilated vertically downward by 3 units
So , the y coordinate is changed to y - 3
Hence , the dilated pentagon is ( x , y ) → ( x + 3 , y - 3 )

Step-by-step explanation:
Alex buys x oranges and Bobbie buys x + 2 oranges. Together they buy 2x + 2 oranges.
$4.20 / $0.21 = 20 oranges.
2x + 2 = 20
2x = 18
x = 9
Hence the value of x is 9.
Answer:
x=9
Step-by-step explanation:
The total number of oranges purchased is x + x+2 = 2x+2
They cost 21 cents each
(2x+2) *.21
This is equal to 4.20
(2x+2) *.21 =4.20
Divide each side by .21
(2x+2) *.21/.21 =4.20/.21
2x+2 = 20
Subtract 2 from each side
2x+2-2 =20-2
2x= 18
Divide by 2
2x/2 =18/2
x =9

Paulo is buying tennis balls that are on sale for 5% off. He uses the expressions t − 0.05t to determine the sale price of the tennis balls. What is an equivalent expression that Paulo could also use to determine the sale price?
Answer:
0.95t
Step-by-step explanation:
Given expression:
t − 0.05t
The equivalent expression could be found by factorizing the expression
t − 0.05t
= t ( 1 - 0.05)
= t (0.95)
= 0.95t
Check
When t = 2
t − 0.05t
= 2 - 0.05(2)
= 2 - 0.1
= 1.9
When t = 2
0.95t
= 0.95(2)
= 1.9
Therefore, the equivalent expression to t − 0.05t is 0.95t

Conner has a coupon for $2.31 off any
purchase of fruit. He decides to buy a
bag of 9 apples which normally cost
$9.33. If Conner uses his coupon, what
will be the price per apple?
Answer:
$0.78 per apple
Step-by-step explanation:
First, find the price of the bag with the coupon:
9.33 - 2.31
= 7.02
Then, find the price per apple by dividing this by 9, since there are 9 apples in the bag:
7.02/9
= 0.78
So, with the coupon, the price per apple is $0.78
If (x+2) is a factor of 3x^2-4kx-4k^2, then find the value(s) of k
Answer:
The values of k will be:
[tex]k=-1,\:k=3[/tex]
Step-by-step explanation:
Let the expression of polynomial P be
[tex]P\left(x\right)=3x^2-4kx-4k^2[/tex]
Let the expression if the polynomial Q be
[tex]\:Q\left(x\right)=\:\left(x+2\right)\:[/tex]
Plug in Q(x) = 0
0 = x+2
x = -2
As (x+2) is a factor of 3x²-4kx-4k²
substitute x = -2 in the the polynomial
3x²-4kx-4k² = 0
[tex]3\left(-2\right)^2-4k\left(-2\right)-4k^2\:=0[/tex]
[tex]12+8k-4k^2=0[/tex]
Write in the standard form ax²+bx+c = 0
[tex]-4k^2+8k+12=0[/tex]
Factor out common term -4
[tex]-4\left(k^2-2k-3\right)=0[/tex]
Factor k²-2k-3: (k+1)(k-3)
[tex]-4\left(k+1\right)\left(k-3\right)=0[/tex]
Using the zero factor principle
if ab=0, then a=0 or b=0 (or both a=0 and b=0)
[tex]k+1=0\quad \mathrm{or}\quad \:k-3=0[/tex]
solving k+1=0
k+1 = 0
k = -1
solving k-3=0
k-3=0
k = 3
Thus, the values of k will be:
[tex]k=-1,\:k=3[/tex]

Describe and correct the error made in finding BC in the diagram Shown. (Hint: It is an Isosceles triangle)
Answer:
BC = 5
Step-by-step explanation:
Since it is an isosceles, it is the base angles that are equal
Since the base angles are equal, then the sides facing these angles are equal
Mathematically, what we are supposed to have as equals should be AB and BC since they are the sides facing the base angles
Thus, BC should be 5

I suggest to make a table
x y
( ) ( )
( ) ( )
and on each section put the points on the correct input and output
once you do that you want to see how much you need to add or subtract to get to the other input or output
For example
if i have ( 5, 10) and ( -5, -10)
I would make a table that looks like this with each of the inputs and outputs.....
x y
5 10
-5 -10
From 10 to -10 you need to subtract 20
from 8 to -8 you need to subtract 10
so y/x
-20/-10
2 negative numbers make a positive so...
your slope will be 2
So with any numbers that they give you, use what I showed u
