Lee has a jar of 100 pennies. She adds groups of 10 pennies to the jar. She adds 5 groups. What numbers does she say?
Answers
100 + 10 = 110
110 + 10 = 120
120 + 10 = 130
130 + 10 = 140
140 + 10 = 150
Thus, all of the numbers she said were 110, 120, 130, 140, and 150.

An alloy consists of nickel, zinc, and copper in the ratio 2:7:9. How much of each metal is needed to make 3.6 kg of this alloy?
Answers
Answer
Find out the how much of each metal is needed to make 3.6 kg of this alloy .
To proof
As given
An alloy consists of nickel, zinc, and copper in the ratio 2:7:9 .
This shows that an alloy contains 18 parts and assume one part of alloy be u .
Thus
An alloy consists of nickel = 2u
An alloy consists of zinc = 7u
An alloy consists of copper = 9u
As given
Total weight of alloy = 3.6 kg
Thus equation becomes
2u + 7u + 9u = 3.6
18u = 3.6
[tex]u = \frac{3.6}{18}[/tex]
u = 0.2 kg
An alloy consists of nickel = 2 × 0.2
= 0.4 kg
An alloy consists of zinc = 7 × 0.2
= 1.4 kg
An alloy consists of copper = 9 × 0.2
= 1.8 kg
Hence proved
To make 3.6 kg of alloy in the given ratio, 400 grams of nickel, 1400 grams of zinc and 1800 grams of copper are required.
Explanation:The question is asking how much of each metal, namely nickel, zinc, and copper, is needed to make 3.6 kg of an alloy with a ratio 2:7:9. To solve this, first, we have to understand that the ratio represents relative amounts of each metal, not their exact weights. The entire alloy is made up of 2 parts nickel, 7 parts zinc, and 9 parts copper - a total of 18 parts. We can find the weight equivalent to one part by dividing the total weight of the alloy - 3.6 kg or 3600 grams - by 18. This gives us 200 grams as the weight of one part. To find the weight of each metal needed, we multiply the weight of one part by the number of parts in the ratio: nickel is 2 * 200 = 400 grams, zinc is 7 * 200 = 1400 grams, and copper is 9 * 200 = 1800 grams.

2n+5<13
minus 5 both sides
2n<8
divide by 2
n<4
Answer:
1. Using Backwards Method, we get,
We have the inequality 2n+5<13.
So, we subtract both the sides by 5,
i.e. 2n+5-5<13-5
i.e. 2n < 8
Now, divide both sides by 2, we get,
[tex]\frac{2n}{2} <\frac{8}{2}[/tex]
i.e. n < 4.
So, using the Backwards method, we get the solution is n<4.
2. Now, we use the Algebraic method,
We have, 2n+5<13
Take 5 to the right side of the inequality,
i.e. 2n<13-5
i.e. 2n < 8
Now, take the 2 on the right side of the inequality.
i.e. [tex]n<\frac{8}{2}[/tex]
i.e. n < 4.
So, again using the Algebraic Method, we get that the solution is n<4.

Mary having her living room and bedroom painted. Interior Designs USA charges $60.00 to evaluate the space plus $35.00 per hour of labor. Splash of Color charges $55.00 per hour with no initial fee. Which of the following are true? Select all that apply.
Answers
The true statement are as follows:
If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective.If it takes 3 hours to paint the rooms, both companies will charge the same amount.Here's a breakdown of why each statement is true or false:
True:
If it takes more than 5 hours to paint the rooms, Splash of Color will be more cost effective. As the painting time increases, the hourly rate becomes a bigger factor, and Splash of Color's lower rate outweighs Interior Designs USA's initial fee advantage.
If it takes 3 hours to paint the rooms, both companies will charge the same amount. Both companies will charge 3 hours of labor at their respective rates: $35/hour * 3 = $105 for Interior Designs USA and $55/hour * 3 = $165 for Splash of Color.
False:
If it takes 7 hours to paint the two rooms, Interior Designs USA will charge the least. Interior Designs USA will cost $60 + $35/hour * 7 = $315, while Splash of Color will cost $55/hour * 7 = $385.
Splash of Color will always charge the least. This is not true because Interior Designs USA can be cheaper for smaller jobs due to their lack of an initial fee (e.g., 1 hour painting time).
If it takes 10 hours to paint the rooms, Splash of Color will charge $200 more than Interior Designs USA. Splash of Color will cost $55/hour * 10 = $550, while Interior Designs USA will cost $60 + $35/hour * 10 = $410. The difference is actually $140, not $200.

In the function y = 10.00x + 35, y represents the cost of cabin lodging per occupant and x represents the number of occupants. How much does the cost increase for every occupant?
Answers
if y is cost per occupant and x is occupants, then we can read the equation as such:
Cost is equal to 10 times number of occupants plus a 35$ fee
10 times the number of occupants is the part we are worried about
The cost increases by 10$ for every occupant
Answer:
$10.
Step-by-step explanation:
We have been given a function [tex]y=10.00x+35[/tex], where y represents the cost of cabin lodging per occupant and x represents the number of occupants.
Since slope of a line is also known as unit rate, so the cost increase for every occupant will be equal to the slope of line.
We can see from our given expression that 10.00x represents the slope of line, so the cost increase for every occupant is $10.
