Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound. How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
A. 0.8 pounds Brand A, 4.2 pounds Brand B
B. 2.7 pounds Brand A. 2.3 pounds Brand B
C. 4.2 pounds Brand A. 0.8 pounds Brand B
D. 2.3 pounds Brand A. 2.7 pounds Brand B
Answer:
C. 4.2 pounds Brand A. 0.8 pounds Brand B
Step-by-step explanation:
How much of each brand of coffee is needed to make 5 pounds that will cost
$6.75/pound?
Let the number of pounds for Brand A = x
Let the number of pounds for Brand B = y
Brand A coffee sells for $7/pound, while Brand B sells for $5.40/pound.
$7 × x + $5.40 × y = $6.75 × 5
7x + 5.40y = 33.75.......Equation 1
x + y = 5 .......Equation 2
x = 5 - y
7(5 - y)+ 5.40y = 33.75
35 - 7y + 5.40y = 33.75
35 - 33.75 = 7y - 5.40y
= 1.25 = 1.6y
y = 1.25/1.6
y = 0.78125 pounds.
Approximately to the nearest whole number, Brand B = 0.8 pounds.
x = 5 - y
x = 5 - 0.8 pounds
x = 4.2 pounds
Brand A = 4.2 pounds
Find the value(s) of "k" that will cause the equation 4x^2 +kx + 4 to have one real solution.
Answer: k = {8, -8}
Step-by-step explanation:
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8

Ray OJ bisects Angle LOK.
Measurement of Angle LOK = 82 degrees.
Solve for x.
Answer:
x = 14
Step-by-step explanation:
<LOJ = 3x
<KOJ = (2x + 12)°
<LOK = 82°
m<LOJ + m<KOJ = m<LOK (angle addition postulate)
3x + 2x + 12 = 82 (substitution)
5x + 12 = 82
5x = 82 - 12 (Subtraction property of equality)
5x = 70
x = 70/5 (division property of equality)
x = 14

Dionne Washington wants to sell natural fruit flavored water at her neighborhood block party. She wrote the amount of money she spent as a function of the number of bottles sold. Which set of numbers would be an appropriate domain for Dionne's function?
Complete question is;
Dionne Washington wants to sell natural fruit flavored water at her neighborhood block party. She wrote the amount of money she spent as a function of the number of bottles sold. Which set of numbers would be an appropriate domain for Dionne’s function?
A) 0, 1, 2, 3, 4, …
B) …, −4, −3, −2, −1, 0
C) …, −3, −2, −1, 0, 1, 2, 3, …
D) …, −3.5, −2.5, −1.5, 0, 1.5, 2.5, 3.5, …
Answer:
Option A: {0,1, 2, 3, 4,....}
Step-by-step explanation:
Domain is simply a set of input while the range is a set of output values.
For example, if we have a function named f(x) = x², the domain will be all possible values of x being inputed while the range will be the value of f(x) for all possible values of x inputed.
Now, from the question, we are told that she wrote the amount of money she spent as a function of the number of bottles sold.
If the number of bottles sold is denoted by "x", it means the function is; f(x).
Now, number of bottles has to be a non-negative whole number or simply a non-negative integer. Thus, the possible values of x are all non-negative whole numbers like, 0,1, 2, 3, 4, 5....
Thus,domain is {0,1, 2, 3, 4,....}

Answer:

Step-by-step explanation:
Answer:
2/3-3/5=10/15-9/15
Step-by-step explanation:
You want a common denominator which here is 15. To get to 15 in 2/3 you needed to multiply by 5 and in 3/5 you needed to multiply by 3.
The points Q, R, S and T all lie on the same line segment, in that order, such that the
ratio of QR:RS: ST is equal to 1:4:5. If QT = 40, find RS.
Answer:
RS=3
Step-by-step explanation:
Solve for x:
6x+3x+x=10
All parts add up to whole
10x=10
Combine like terms
x=1
Use x to solve for segment lengths:
QR=6x=6(1)=6
RS=3x=3(1)=3
ST=x=1
Therefore RS=3
The length of the line segment RS will be 16 units.
What are collinear points?An axis is a term used to describe a line on which points are located, particularly if that line is connected to a triangle or other geometric shape. Since two factors determine a line, two points are transparently collinear. If the points are in a line, then the points are collinear points.
Let Q, R, S, and T be the collinear points. Then the condition of the collinear will be
QR + RS + ST = QT
The points Q, R, S, and T all lie on the same line segment, in that order, such that the ratio of QR:RS: ST is equal to 1:4:5. If QT = 40.
Let QR / 1 = RS / 4 = ST / 5 = x
QR = x
RS = 4x
ST = 5x
Then the value of the variable x will be
QR + RS + ST = QT
x + 4x + 5x = 40
10x = 40
x = 4
Then the length of the line segment RS will be
RS = 4x
RS = 4 (4)
RS = 16
Then the length of the line segment RS will be 16 units.

Rewrite the following expression: x3 + x5 =
Answer:
x + 8 = x8
Step-by-step explanation:
This is one of the many ways to rewrite this equation. The reason this is a way of rewriting it is because 3x plus 5x equals 8x and if you take away the variable from 3 and 5 and add the numbers together you get 8. So take the variable x add it to 8 and you get x8. Both equations have the same answer so therefor this is another way of writing the equation.

The stem-and-leaf plot shows the test scores of a science class. Use the plot to answer the question.
How many students scored 78?
Answer:
4 students
Step-by-step explanation:
Understanding stem-and-leaf plots
A stem and leaf plot is designed in a way to group the numbers by their values before the ones place;
i.e. 92, 100, 101, 103, 113
Charted as
9 | 2
10 | 0 1 3
11 | 3
So, with that in mind we know 78 is grouped under the 7 | # # #
stem and has the leaf of 8 which is displayed by # | # # # 8
SO,
TO SOLVE:
Count the 8's under the 7 | # # # # group
We can see that there are 4 8's under that section, and assuming that each number is representative of one students score, we can conclude that 4 students scored 78
