Country Carpets charges $22 per square yard for carpeting, and an additional installation fee of $100. City carpets charges $25 per square yard for the same carpeting and an additional installation fee of $70. Write and solve an equation to find the number of square yards of carpeting for which the total cost charged by the two companies will be the same.
Answers
Answer:
10
Step-by-step explanation:
country carpets: y = 22x + 100
City carpets: y = 25x + 70
22x + 100 = 25x + 70
I could be wrong but I hope this helps!
Answer:
10 square yards
Step-by-step explanation:
25x+70= t
22x+100= t
25*10= 250+70= 320
22*10=220+100= 320

Ganesh is making a scale model of the Space Needle in Seattle, Washington. The Space Needle is 605 feet tall. If the model is the actual size of the Space Needle, how tall is the model?
Show all your thinking.
Answers
Answer:
it says if it was the exact same size thats what i understood so it would be 605ft tall
Step-by-step explanation:
Answer:
The model is 6.05 feet tall.
Step-by-step explanation:
Now to the breakdown.
What does it mean to scale? Scaling is used for representation drawing or model is designed to tell the audience(those interested in the design) the ratio to which the design was done in respect to the actual size.
From the above definition we can scale down or scale up. To scale down is to reduce the dimensions of the actual size in our design (possibly in an effort to conserve available space). To scale up is to enlarge the dimensions of the actual size in our design (possible in an effort to show intricate and tiny parts).
Back to question, The actual size of the space needle is 605 feet to design this using the actual size will require a very large amount of resources. So the scale model is made at a scaled down ratio of 1:100 (in a bid to manage available resources like paper size and others pertaining to the design).
1:100 means that every 1ft in the scale model represents 100ft of the actual model.
So for an Height of 605ft the scale model will have representing height of 605/100 = 6.05ft.

In a northwestern U.S. town, the peak temperature is 96° Fahrenheit in August. After the peak, it drops an average of 4° Fahrenheit per week. The graph below models the number of weeks it would take the temperature to drop below freezing, 32° Fahrenheit.
okay so they show a pic of a number line from 10-22 and the 16 number has a ray with a open circle!?
Which of the following is the correct interpretation of the solution?
A. It would take more than 16 weeks to drop below freezing.
B. It would take 16 or less weeks to drop below freezing.
C. It would take less than 16 weeks to drop below freezing.
D. It would take 16 or more weeks to drop below freezing.
Answers
Answer:It would take more than 16 weeks to drop below freezing.
The temperature is dropping from 96°F to 32°F at a rate of 4°F per week, where 32°F is the freezing point.
Hence, 32 = 96 - 4w { Where w week is required to reach 32°F }
⇒ 4w = 64
⇒ w = 16
Therefore, it would take more than 16 weeks to drop below freezing. ( Answer )

Amy will rent a car for the weekend. She can choose one of two plans. The first plan has an initial fee of $38 and costs an additional $0.12 per mile driven. The second plan has an initial fee $51 of and costs an additional 0.08 per mile driven.
For what amount of driving do the two plans cost the same?
What is the cost when the two plans cost the same?
Answers
Answer:
325 miles and 77 dollars
Step-by-step explanation:
First, create equations. Let x equal the miles driven. The first plan expression is 38 + 0.12x and the second plan expression is 51 + 0.08x. Setting these equal and solve for x: 38 + 0.12x = 51 + 0.08x -> 0.04x = 13 -> x = 325 miles.
The cost is found by substituting it into any of the expressions: 51 + 0.08(325) = 77 or 38 + 0.12(325) = 77

Which number line shows 1 to 4 divided into thirds?
Answers
Answer:
Line 1.
Step-by-step explanation:
This is because in order for it to be considered thirds, the third has to equal a whole. Line one goes:
1/3 2/3 3/3
This is split into thirds
The required number line that represents the dividend of the three is the fourth line. Option D is correct.
Given that.
To determine the line that has a dividend of 3.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
Line 1 has a dividend of 2,
Line 2 has a dividend of 5
Line 3 has a dividend of 4
Line 4 has a dividend of 3
Thus, the required number line that represents the dividend of the three is the fourth line. Option D is correct.

Soup A has 5 grams of sodium in every 12 cups. Soup B has 8 grams of sodium in every 13 cups. Which soup has more sodium per cup?
Answers
Answer:
Soup B has more sodium per cup.
Step-by-step explanation:
If we're doing sodium per cup, then we have to divide 5 by 12, and 8 by 13.
5÷12=~0.4 grams
8÷13=~0.6 grams
0.6>0.4
So B has more sodium per cup.
