Answer:
400
Step-by-step explanation:
The current number is 100, it doubles every ten days, and you're asking what the size will be in twenty days.
Beginning:
100 ants (ten days pass)
100 x 2 = 200
Middle:
10 of the 20 days have passed
Your new number is 200 ants
End:
200 ants (ten days pass)
Since every ten days the size doubles: 200 x 2 = 400
400 ants after 20 days
PLEASE HELP The ratio of athletes in the two teams is 3:2. After 12 athletes move from first team to second, the ratio is 5:4. Find the number of athletes on each team originally.
Answer:
You can use the method of substitution and elimination.
Team A : Team B
3x : 2x
-12 +12
5y : 4y
3x-12=5y ---> (1)
2x+12=4y ---> (2)
12x-48=20y
10x+60=20y
12x-48=10x+60
12x-10x=48+60
= 108
2x=108
x=54
Original number of athletes on Team A = 3(54)
= 162
Original number of athletes on Team B = 2(54)
= 108

A fruit market equally divided 80 red apples into 8 containers, and equally divided 54 green apples into 6 containers. Natalie bought 1 container of red apples and 1 container of green apples.
Which equation could be used to find n, the total number of apples Natalie bought?
80 ÷ 6 + 54 ÷ 8 = n
80 ÷ 8 + 54 ÷ 6 = n
(80+54)÷(8+6)=n
80 × 8 + 54 × 6 = n
Answer:
The second one
Step-by-step explanation:
80 / 8 tells how many red
+ 54 / 6 tells how many green

Jean is x years old and jonathan is y years old how many years older is jean then jonathan. How old was jean 5 years ago
Answer:
x - y is the difference in the kids' ages
x - 5 represents Jean's age 5 years ago
Step-by-step explanation:
If Jean is older, write her age (x) before Jon's age (y): x - y. This is as far as we can go with the limited info you have shared.
Jean is x years old, so 5 years ago her age was x - 5.
Write the phrase as an expression. Then evaluate the expression when y=20.

Miss Riley's class has 24 students. She has the students in groups. Each group can have no more than 5 students. if every student has to be in groups how many does she have left?
Answer:
if there can be no more than 5 students, then anything less than 5 students will suffice. However we don’t want any left over ones cause we don’t want that one kid sitting alone during lunch so we can simply put 4 into each group.
Step-by-step explanation:
Hope this helped :DDD
Answer:
6 groups, 4 students in each one
Step-by-step explanation:
The factors of 24 include 6 and 4
That means that you can break 24 into those numbers
You are able to put the students up into groups of 6, with 4 students in each
However, you cannot place the students into groups of 4 (with 6 students in each) because no more than 5 students are allowed in each group

Line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A prime B prime. What is the length of A prime B prime? (5 points)
1 unit
2 units
3 units
5 units
Answer:
The correct option is C.
Step-by-step explanation:
It is given that line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A'B'.
Translation is a rigid transformation. It means the shape and size of preimage and image are same. In other words we can say that the preimage and image are congruent.
Corresponding sides of congruent figures are congruent.
The length of A'B' is 3 units. Therefore the correct option is C.

if she biked 95 each day, we just find how many days it’ll take.
2912/95=30.65 or 31 days if you want to use 31 I advise you to use 30.65
even though this seems improper, if you multiply 30.65 by 95 you’ll still get 2912

How would you solve this problem? (Worth 10 points, pls help!)
Answer:
(22,0)
Step-by-step explanation:
1. Select any two points given and find their slope (rise/run)
(-38, 40) and (-23, 30)
slope = [tex]\frac{40-30}{-38-(-23)}[/tex] = - 2/3
2. Use the slope and one of the points to create an equation of the line in the format y = mx + b, where m = slope and b = y-intercept.
y = mx + b ⇒ 40 = -2/3 (-38) + b
3. Solve for b
40 = -2/3 (-38) + b
40 = 76/3 + b
40 - 76/3 = b
b = 44/3
4. To find the x-intercept, set y = 0, and solve.
y = -2/3 x + 44/3
0 = -2/3 x + 44/3
2/3 x = 44/3
x = 22
Hope this helped!

Evaluate 1/5y + 4/15 when y = 1/3
Answer:
= [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
First, plug-in y for 1/3 since y = 1/3
[tex]\frac{1}{5} (\frac{1}{3} ) + \frac{4}{15}[/tex]
then multiply first according to the order of operations, then do the addition:
[tex]\frac{1}{5} * \frac{1}{3} =\frac{1}{15}[/tex]
[tex]\frac{1}{15} + \frac{4}{15}[/tex] = [tex]\frac{5}{15}[/tex]
then reduce:
[tex]\frac{5}{15} \to \frac{2}{3}[/tex]
