Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
Answer:
2/3
Step-by-step explanation:
Glenn needs to cut pieces of ribbon that are each 1 meter long to make ribbon key chains. If he has 6 pieces of ribbon that are each 1 dekameter long, how many 1−meter pieces of ribbon can he cut?
1 decametre = 10 metres
Hence,
10 meters = 6 pieces of ribbon
1 meter = x pieces
Cross Multiply
10x = 6
x = 6/10
x = 2/3 (1 meter pieces of ribbon)

if 2 quantities are in direct proportion, what happens if one quantity increases?
In triangle 4JKL, we have JK = 9 and KL = 15. If JL is an integer, what are the largest and smallest possible values for JL?
Answer:
The largest possible value is 23
The smallest is 7
Step-by-step explanation:
To get the length of JL, we use the triangle inequality theorem
The theorem is that the sum of the measure of any two sides of a triangle must be greater than the measure of the third side of the triangle for the triangle to exist
With respect to this, 9 + 15 must be greater than JL
since JL is an integer ( integers are whole numbers); we have the following
9 + 15 = 24
JL is less than 24; so the nearest integer closest to 24 is 23
Now, let us get the smallest possible value
For the smallest possible value;
Let us call that x
9 + x > 15
15 + x > 9
From the first inequality;
x > 15-9
x > 6
The smallest integer greater than is 7
So the smallest possible value for JL is 7 and the largest is 23
Jenna bought enough lattes for all her friends. Each latte was $3.50
and she gave the barista a $20 bill, who then gave her back $2.50
in change. Write an equation modeling this, with x as the cost per late
How many lattes did she buy?
Answer: 5 lattes
Step-by-step explanation: Our equation is 20 − 3.5x = 2.5, which means x = 5 lattes.
Answer:
Step-by-step explanation:
y=3.5x (cost function where y is cost and x is the number of lattes)
20-2.5=3.5x
17.5=3.5x
5=x
So she bought 5 lattes.

Mis. Jackson wants to rent a van for a week it will cost a weekly fee plus 0.20 per mile driven let m equal the number of miles Ms. Jackson drives during the week write an algebraic expression that shows a week rent Jackson will pay for the van for the week
Answer:
A = w + 0.20m
Step-by-step explanation:
Step 1
We find the equation for the total amount spent in a week
The total amount to rent the van in a week = A
Weekly fee = w
Number of miles = m
Therefore, thw algebraic expression that shows a week rent Jackson will pay for the van for the week is
A = w + 0.20m

In a biology lab, 500 bacteria reproduce by splitting. Every hour, on the hour, each bacterium splits into two bacteria.
Answer:hour 1 500, hour 2 1000, hour 3 2000 , hour 4 4000
Step-by-step explanation:
After 1 hour 500 bacteria split into 500 bacteria.
After 2 hour 500 bacteria split into 1000 bacteria.
After 3 hour 500 bacteria split into 1500 bacteria.
After 4 hour 500 bacteria split into 2000 bacteria.
Given that,
In a biology lab, 500 bacteria reproduce by splitting.
Every hour, on the hour, each bacterium splits into two bacteria.
We have to find,
Find the number of bacteria after 4 hours.
According to the question,
Let us assume n = the number of bacteria at a given hour.
Total number of bacteria = 500
At the end of 1 hour each of the 500 bacteria after an hour is split in to 2 bacteria. So, at the end of 1 hour = n(1) = 1 × 500 = 500 After 1 hour 500 bacteria split into 500 bacteria.At the end of the 2 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(2) = 2 x 500 = 1000 bacteria After 2 hour 500 bacteria split into 1000 bacteria.At the end of the 3 hour, each of the 500 bacteria will split in to 2 more bacteria. So, n(3) = 500 x 3 = 1500 bacteria After 3 hour 500 bacteria split into 1500 bacteria.At the end of 4 hours, each of the 500 bacteria spilt into 2 more bacteria.
So, n(4) = 4 × 500 = 2000 bacteria
After 4 hour 500 bacteria split into 2000 bacteria.
