Answer:
Let's define the variables:
x = yards of Organza ribbon that you buy.
y = yards of Satin ribbon that you buy.
We know that the price per yard of Organza ribbon is $0.07, this means tat if you buy x yards, the cost will be:
C = x*$0.07
And the cost of the Satin ribbon is $0.04, so if you buy y yards of that ribbon, the cost will be:
C = y*$0.04
Adding that together, the total cost is:
C = x*$0.07 + y*$0.04
Now we know that you pay $5, this means that the total cost is exactly $5, then we have the equation:
$5 = x*$0.07 + y*$0.04
Now we can isolate the variable y to get:
y = ($5/$0.04) - x*($0.07/$0.04)
y = 125 - x*1.75
Now we can just input different values of x to find the correspondent value of y.
This means that:
if x = 0 (0 yards of the Organza ribbon)
then:
y = 125 - 0*1.75 = 0
This combination is:
0 yards of organza, and 125 yards of satin.
Now, if x = 20, then:
y = 125 - 20*1.75 = 90
This combination is:
20 yards of organza, and 90 yards of satin.
if x = 40, then:
y = 125 - 40*1.75 = 55
This combination is:
40 yards of organza, and 55 yards of satin.
The 3 combinations that we found cost exactly $5.
Seven of the 28 dogs at the shelter are purebred. What percent of the dogs are purebred? (Please help I have been stuck on this question for an hour)
The question is set up btw-
Answer:
25% are purebred
Step-by-step explanation:
7 out of 28 dogs are purebred
7 x 10 = 70
28 x 10 = 280
70 / 280 = 2.5 / 10 = 25 / 100 = 25%
x-y=-3
please answer this right
Answer:
x +3 = y
Step-by-step explanation:
So you are looking for mx + b = y
m is the slope
b is the initial value
Try to isolate the y variable
x - y = -3
Subtract x from both sides
-y = -x - 3
Multiply everything by -1 to make the y value positive
y = x + 3
A studio apartment measures 26 feet by 39 feet. It sells for 295 per square foot. What is the total cost of the apartment
Answer: 299130 dollars is the total cost of the apartment.
Step-by-step explanation:
26 time 39 is 1014. Additionally, 1 square foot is 295 dollars per square foot. Meaning 1014 x 295 is 299130.
Thirty-two cyclists make a seven-day trip. Each cyclist requires 8.33 kilograms of food for the entire trip. If each cyclist wants to eat an equal amount of food each day, how many kilograms of food will the group be carrying at the end of Day 5?
Answer:
76.16 kilograms of food
Step-by-step explanation:
Number of cyclist = 32
Food per cyclist = 8.33 kilograms
Days of the trip = 7 days
Food per cyclist per day = 8.33 kg / 7
= 1.19kg food per day for each cyclist
how many kilograms of food will the group be carrying at the end of Day 5?
5 days out of 7 days = 2 days
Each cyclist will have to carry = 2 × 1.19 kg of food for the remaining two days
= 2 × 1.19
= 2.38 kilograms of food for two days
32 cyclist for 2 days = 32 × 2.38 kg of food
= 76.16 kilograms of food
The group will be carrying 76.16 kilograms of food at the end of Day 5

12x^2=24
Answer:
x=√2 or x=−√2
x=±√2
Step-by-step explanation:
12x^2=24
Step 1: Divide both sides by 12!
12x^2/12=24/12
x^2=2
Step 2: Take the square root!
x=±√2
The solution of the equation 12x² = 24 is x = ±√2.
What is Algebraic expression ?
Algebraic expressions are the idea of expressing numbers using letters or alphabets without specifying their actual values. The basics of algebra taught us how to express an unknown value using letters such as x, y, z, etc. These letters are called here as variables. An algebraic expression can be a combination of both variables and constants. Any value that is placed before and multiplied by a variable is a coefficient.
Here, the equation is :
12x² = 24
now, to solve for x :
divide both side by 12 :
x² = 24/12
x² = 2
take square root both side :
x = ±√2
Therefore, the solution of the equation 12x² = 24 is x = ±√2.

The difference between one-half a number and the number is 8 find the number
Answer:
The number is 48
Step-by-step explanation:
First, let's call the number we are looking for n.
We can then write "two-thirds of the number" as 2/3n
We can also write "one-half of a number" as 1/2n
Finally, we are told 1/2n is the same as 2/3n −8 or: 1/2n = 23n −8
We can now solve for n: 1/2n − 2/3n = 2/3n −8 − 2/3n 1/2n − 2/3n = −8We next need to get the fractions over common denominators, in this case, 6 by multiplying each fraction by the necessary for of 1: (3/3) 1/2n − (2/2) 2/3n = −8 3/6n − 4/6n = −8 − 1/6n = −8.
We can finally solve for n by multiplying by -6 to isolate n −6 ⋅(−1/6)n = −8⋅ − 6
1n = 48
n =48

Please help me with this question!!
Answer: The answer is B
Step-by-step explanation:
Look at A- You can see that it wants you to go to English and see that 50 freshmen chose english. Then, you go to undecided, you see that it has 50 freshmen who chose it as well. They are the same, so it is false.
Look at B- You can see that it wants you to go to Education and see that 60 people chose Education. Then you go to both Science or other and see that they are both less than Education. So, this statement would be correct.
Look at C- You can see that it wants you to go to business or Education and see that 45 people chose business and 60 people chose education. Go to science, 35 people chose science and 40 chose engineering. This is false.
Look at D- 45 people chose business as their major and 50 chose english as their major, so no this wouldn't be correct because 45 if less than 50 and it says that it would be greater than 50.
So, B would be the correct answer to this problem.

which equation represent the line that passes through the point(-3.4,8.3) and has a slope of 6.5
Answer:
y - 8.3 = 6.5(x + 3.4) {the point-slope form of the equation}
y = 6.5x + 30.4 {the slope-intercept form of the equation}
65x - 10y = - 304 {the standard form of the equation}
Step-by-step explanation:
The point-slope form of equation is: y - y₀ = m(x - x₀), where (x₀, y₀) is any point the line passes through and m is the slope.
m = 6.5
(-3.4, 8.3) ⇒ x₀ = -3.4, y₀ = 8.3
The point-slope form of the equation:
y - 8.3 = 6.5(x + 3.4)
So:
y - 8.3 = 6.5x + 22.1 {add 8.3 to both sides}
y = 6.5x + 30.4 ← the slope-intercept form of the equation
y - 6.5x = 30.4 {multiply both sides by (-10)}
65x - 10y = - 304 ← the standard form of the equation

what is 9/10 divided by 3.8 ? By quotient
Given:
[tex]\dfrac{9}{10}[/tex] divided by 3.8.
To find:
The quotient.
Solution:
We have,
[tex]\dfrac{9}{10}[/tex] divided by 3.8.
Mathematically it can be written as
[tex]\dfrac{9}{10}\div 3.8[/tex]
Convert the decimal into fraction by multiplying and dividing by 10.
[tex]=\dfrac{9}{10}\div \dfrac{38}{10}[/tex]
[tex]=\dfrac{9}{10}\times \dfrac{10}{38}[/tex] [Reciprocal rule of division]
[tex]=\dfrac{9}{38}[/tex] (Cancel out the common factors)
[tex]\approx 0.237[/tex]
Therefore, the quotient is [tex]\dfrac{9}{38}[/tex], which is approximately 0.237.
