Rachel has a ribbon that is 16.2 metres long. Sheena has a ribbon that is 8.3 metres shorter than Rachel's ribbon.What is the total length of the two ribbons?
Answer:
24.1m
Step-by-step explanation:
We have these informations to answer this question with.
Length of Rachel's ribbon = 16.2 m
Sheena's ribbon = 8.3m shorter than Rachael's
So,
Sheena's ribbon = length of Rachael's ribbon - 8.3m
= 16.2m - 8.3m
= 7.9m
The total length of the two ribbons
= length of Sheena's ribbon + length Rachael's ribbon
= 16.2 + 7.9
= 24.1 m
A number minus twice another number is 4. Three times the first number plus two times the second number is 12. What are the numbers?
Answer:
4 and 0
Step-by-step explanation:
I hope this helps
The first number is 4 and the second number is 4.
What is the system of equation?One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.
Given:
A number minus twice another number is 4.
Three times the first number plus two times the second number is 12.
Let numbers are n and m.
According to the question;
n- 2m = 4 equation 1
3n + 2m = 12 equation 2
Now, we have the system of equation.
To solve the equation,
Add both of the equation,
4n = 16
n = 4
Then m = 0
Therefore, 0 and 4 are the numbers.

It was recently estimated that homes without children outnumber homes with children by seven to five. If there are 3564 homes in the county, how many of them are homes without children
Answer:
2079
Step-by-step explanation:
Homes without children outnumbers homes with children by about 7 to 5 ;
If number of children = 3564
Number of homes without children :
Expressing the relaship interms of ratio :
Without children : with children = 7 :5
Total ratio = 7 + 5 = 12
Number of homes without children:
(7 / 12) * 3564
0.5833333 * 3564
= 2079

Describe the features of the Free-market system
Answer:People often use the terms free enterprise, free market, or capitalism to describe the economic system of the United States. A free enterprise economy has five important characteristics. They are: economic freedom, voluntary (willing) exchange, private property rights, the profit motive, and competition.
Step-by-step explanation:
Answer:
Feature 1 # Property Rights:Property rights are social institutions that govern the ownership, use and disposal of resources, goods and services.
Feature 2 # Freedom of Private Enterprise:Allied to the property rights is freedom of enterprise which is another basic feature of a market economy. Freedom of enterprise means that everybody is free to engage in whatever economic activity he pleases. In other words, he is free to choose to work in any industry he likes or adopts any occupation or trade he desires.
Feature 3 # Profits and Prices: Incentives and Information:No individuals would work and save if adequate incentives are not provided to them in the form of wages and interest respectively. Similarly, the firms will not produce goods and services and bear risk of losing money if sufficient incentives are not given to them. Profits are earned from undertaking the task of producing goods and services and introducing new products and new techniques of production. Profits earned by the firm depend on prices of goods and services produced and cost incurred.
Feature 4 # Competitive Markets:In ordinary speech the word market means a place where buyers and sellers meet to buy and sell goods. In economics, market has a wider meaning and is interpreted to mean any arrangement that enables buyers and sellers to exchange things; they may contact each other through telephone, fax or direct computer link to negotiate prices of goods they buy and sell. In our above example, rational and self-interested consumers and profit-maximizing firms contact each other through any media and buy and sell things on the negotiated price.

What is X+Y?? and ( x+ y)- 7+8
Step-by-step explanation:
What is X+Y?
First note that if x + y = xy then neither x nor y can be equal to 1.
That being said, as a previous user already noted y = x/(x-1) and hence x - y = x - x(x-1) = x(x-2)/(x-1). Assume x - y = D. Then your question becomes what can D be so that the equation x(x-2)/(x-1) = D has a solution different than 1.
Rewrite this equation as x(x-2) = D(x-1) and note that x(x-2) = (x-1)^2 - 1. Replace x - 1 with z. So your question is what can D be so that the equation z^2 - 1 = Dz has a nonzero solution? Given that 0 cannot be a solution anyway of the previous equation. The question is really, for which D does the quadratic equation z^2 - Dz - 1 = 0 have solutions? By elementary 9th grade math, this equation has a solution when its discriminant D^2 + 4 is nonnegative. But D^2 + 4 is strictly positive regardless of the value of D. Hence D can be anything.

At 3pm the outside Temperature was 4°F . The Temperature then fell steadily by 2°F every hour for the next four hours . What was the temperature at 7 PM
Answer:
Step-by-step explanation:
Temperature at 3pm: 4° F
After the decrease in temperature per hour by 2°F
Temperature at 4pm: 2°F
Temperature at 5pm: 0°F
Temperature at 6pm: -2°F
Temperature at 7pm:-4°F
Hence we can say that the temperature at 7pm is -4°F

1.Ms. Bowery bought five shirts and one pair of pants for a total of $56.23. Each shirt cost
the same price. The pants cost $7 more than a shirt. How much did each shirt cost? Round to
the nearest dollar and cent
A) $9.20
B) $49.26
C) $8.20
D) $10.20
Answer:
[tex]\mathrm{C)\:} \$8.20[/tex]
Step-by-step explanation:
Let [tex]s[/tex] represent the cost of each shirt in dollars. We can write the cost of the pants as [tex]s+7[/tex]. Using these terms, set up the following equation:
[tex]5s+(s+7)=56.23[/tex].
Solving, we get:
[tex]5s+s+7=56.23,\\6s=56.23,\\6s=49.23\\s\approx \fbox{$\$8.20$}[/tex]

Is this a function?
You can buy 20 fluid ounces of shampoo for $4.40 or, you can buy 24 fluid ounces for $4.80 which is the better buy? Please answer in complete sentences and i will give brainliest with most detail please don answer for points i will delete your answer
Answer: the 20 fluid ounces is better
Step-by-step explanation:
If you divide 20 by 4.40 that is 4.54 but if you divide 24 by 4.80 that is 5. You want to divide 20 by 4.40 because 20 is the fluid ounces and 4.40 is the money divide that to get the cost per fluid ounce then you do the same with the 24 fluid ounces and by doing that you get the sot for 1 fluid ounce then look at both of your answers and see which one is less. which one is less is the better one.

g(x)=2x-5 h(x)=x^2-2
find g(h(-8))
Answer:
g(h(- 8)) = 119
Step-by-step explanation:
Evaluate h(- 8), then substitute the result obtained into g(x), that is
h(- 8) = (- 8)² - 2 = 64 - 2 = 62, then
g(62) = 2(62) - 5 = 124 - 5 = 119
