Jack bought 24 apples at the farm stand. He divided the apples between his brother, his friend, and himself in a ratio of 2:1:3. How many apples did each person receive?
Answer: 8,4, and 12
Step-by-step explanation:
Given
Jack bought 24 apples and divided them in the ratio of 2:1:3.
Suppose they get the number of apples as [tex]2x,x,3x[/tex] such that their ratio remains the same
[tex]\therefore 2x+x+3x=24\\\Rightarrow 6x=24\\\Rightarrow x=4[/tex]
So, each person gets
[tex]2x=2\times 4=8\\x=4\\3x=3\times 4=12[/tex]
Answer:
Jack's brother received 8 apples, his friend received 4 and Jack received 12 apples.
3/4+ (1/3 ➗1/6)- (-1/2)=___
1 3/4
2 1/4
3/4
3 1/4
STEP 1: (1/3 : 1/6) = 2/1 = 2
STEP 2: 3/4 + 2 = 11/4 = 2 3/4 = 2.75
STEP 3: 2.75 (-1/2) = -11/8 = -1 3/8 = -1.375
(1) Divide: 1/3 : 1/6 = 1/3 · 6/1 = 1 · 6/3 · 1 = 6/3 = 3 · 2 /3 · 1 = 2
(2)Add: 3/4 + the result of step No. 1 = 3/4 + 2 = 3/4 + 2/1 = 3/4 + 2 · 4/1 · 4 = 3/4 + 8/4 = 3 + 8/4 = 11/4
(3) Subtract: the result of step No. 2 - (-1/2) = 11/4 - (-1/2) = 11/4 - (-1) · 2/2 · 2 = 11/4 - (-2/4) = 11 - (-2)/4 = 13/4
Therefor your answer is A 13/4 OR 1 and 3/4: )
Hope this helps!

if you can attempt to type out a table... that would be great lol.
Answer: 50% or 1/2
Step-by-step explanation:
number of possible combos:
1+1, 1+2, 1+3, 1+4, 1+5, 1+6
2+1, 2+2, 2+3, 2+4, 2+5, 2+6
3+1, 3+2, 3+3, 3+4, 3+5, 3+6
4+1, 4+2, 4+3, 4+4, 4+5, 4+6
5+1, 5+2, 5+3, 5+4, 5+5, 5+6
6+1, 6+2, 6+3, 6+4, 6+5, 6+6
number of even sums within combos:
1+1, 1+3, 1+5
2+2, 2+4, 2+6
3+1, 3+3, 3+5
4+2, 4+4, 4+6
5+1, 5+3, 5+5
6+2, 6+4, 6+6
TOTAL combos:
36
TOTAL even sums:
18
so that means 18/36 or 1/2 of the possible combinations has a sum of an even number.

Kyle divided his stamps
evenly on 3 pages with
6 stamps on each page.
How many stamps are
in Kyle's stamp
collection?
Answer:
18
Step-by-step explanation:
Each page has 6 stamps. There are 3 pages. This is a simple multiplication problem, and so you do 3x6 to find the total number of stamps Kyle has. Thus, 3 times 6 is 18.
visual:
Page One: 6 stamps
Page Two: 6 stamps
Page Three: 6 stamps
6 + 6 + 6 = 18 (or just do 6x3)

Hannah ordered books for her son from an online retailer. Each book costs $7.25 and there is a shipping fee of $6.75 for the entire order.
(a)
Part A
What is the cost of Hannah's order if she buys 9 books?
$
Part B
Write a sentence to describe how you calculate the cost of Hannah's order.
Answer:
Part A:
1 book -- $7.25
9 books -- (9 * 7.25) = $65.25
And shipping fee -- (65.25 + 6.75) = $ 72
Part B
9 multiplied by the cost and added with the shipping fee to get Hannah's total cost.
Thenks and mark me brainliest :))
A square has a perimeter of 8g + 16. Which expression also represents the perimeter given the side length of the square?
Answer:
4(2g+4)
Step-by-step explanation:
8g+16
Since this expression represents the total perimeter, we need one side length. So we divide this by 4, because it's a square and all sides are of equal length.
8/4=2
16/4=4
One side is 2g+4. So multiply that equation by 4.
4(2g+4)
DOUBLE CHECK
4(2g+4)
8g+16

hope it helps
Answer:
4(2g+4) :):):):):):):):):):):):)
Ann had 96 filers to post around town. Last week, she posted 1/4 of them. This week, she posted 1/3 of the remaining filers. How many filers has she still not posted
Answer:
48 [fliers]
Step-by-step explanation:
Ann starts with 96 fliers. After she posts 1/4 of them, she will have 3/4*96=72 fliers left. She now has 72 remaining flyers. After posting 1/3 of these, she will have 2/3*72=48 fliers left.

URGENT!! Two students determined the value of this expression. -2.5(1.4+3.1) + 6.9(-4.3)
These are the steps each student used.
Student P Steps:
Step 1: -3.5 + 7.75 + 6.9(-4.3)
Step 2: -3.5 + 7.75 - 29.67
Step 3: 7.75 - 3.5 - 29.67
Step 4: -25.42
Students Q steps:
Step 1: -3.5 - 7.75 + 6.9(-4.3)
Step 2: -3.5 - 7.75 - 29.67
Step 3: -(3.5 - 7.75 - 29.67)
Step 4: -(-33.92)
Step 5: 33.92
Analyze the steps and describe any errors made by Student P and Student Q
Answer:
student p= added and subtracted wrongs
stident Q= only subtracted
Step-by-step explanation:
The error of student P is the first step and that of student Q is the third step.
What are Expressions?Expressions are mathematical statements which consist of two or more terms and terms are connected to each other using mathematical operators like addition, multiplication, subtraction and so on.
Given expression is
-2.5 (1.4 + 3.1) + 6.9 (-4.3)
Using the distributive property,
= (-2.5 × 1.4) + (-2.5 × 3.1) + (6.6 × -4.3)
= -3.5 - 7.75 - 29.67
= - (3.5 + 7.75 + 29.67)
= -40.92
This is the correct way to do the operations.
The error of student P is in the step 1, where the student wrote 7.75 instead of -7.75.
The error of student Q is in the step 3, that when the negative sign is taken out all the signs inside the bracket become positive.
Hence the errors of two students are found.

Find the measures of an exterior angle and an interior angle given the number of sides of each regular polygon.
Round to the nearest tenth, if necessary.
Answer:
[tex]\theta = 25.7^\circ[/tex] --- Measure of each exterior angle
[tex]\theta = 154.3^\circ[/tex] --- Measure of each interior angle
Step-by-step explanation:
Given [Missing from the question]
[tex]n = 14[/tex] --- number of sides
Required
- The measure of an exterior angle
- The measure of an interior angle
For an n-sided polygon, the measure of each exterior angle is:
[tex]\theta = \frac{360}{n}[/tex]
Substitute 14 for n
[tex]\theta = \frac{360}{14}[/tex]
[tex]\theta = 25.7^\circ[/tex]
For an n-sided polygon, the measure of each interior angle is:
[tex]\theta = \frac{(n - 2) * 180}{n}[/tex]
Substitute 14 for n
[tex]\theta = \frac{(14 - 2) * 180}{14}[/tex]
[tex]\theta = \frac{12 * 180}{14}[/tex]
[tex]\theta = \frac{2160}{14}[/tex]
[tex]\theta = 154.3^\circ[/tex]

Please Help me with this question!! I have a time limit
The Garcia family drives 3/4 of the distance to their grandparent's house
in 3/4 hour.
How many hours will it take
to drive to their grandparent's house at the same rate?
a= 1
b=9/16
c=1 and 7/9
Answer:
a=1
Step-by-step explanation:
because 3/4 hour is 45 minute and it takes 4/4 distance to their grandparents hous ein 4/4 hour so 45÷3=15, 15×4=60 which is 1hour
The Answer is A: 1 hour
Step-by-step explanation:
since they can drive 3/4 the distance in 3/4 hours, they can also drive 1/2 the distance in 1/2 hours and so on. If they want to visit the grandparent's house, they need to drive 4/4 the distance which is equivalent to 1 so it will take 1 hour for them to go to the house at the same rate.

What two numbers equal 6 when multiplied but equal —7 when added?
Answer:
-1 , -6
Step-by-step explanation:
Let x be the first number and let y be the second number.
x * y = 6
x + y = -7
Let's first find the factor pairs of 6.
1, 6
2, 3
-1, -6
-2, -3
Now, we just need to take each factor pair and add them together and see which one equals -7.
1 + 6 = 7, so that is wrong.
2 + 3 - 5, so that is also wrong.
-1 - 6 = -7, so this is our answer (-2 and -3 added is -5, which is wrong).
Therefore, our answer is -6 and -1.
