The telephone company purchased 192 yards of wire for $2,304 in January. They
plan on making a purchase of 400 yards in February. How much will the February
purchase cost?
Answer:
Step-by-step explanation:
400yd($2304/192yd)=$4800
Answer:
400 yards of wire will cost $4,800
Step-by-step explanation:
First find the cost per yard of wire by using the equation 2,304/192 which equals 12/1, which is $12 per yard of wire. Next multiply that by 400 to get $4800, which is the total February purchase cost.

A cinema has 300 seats. 60% are filled. How many are empty? i will give brainliest
Answer:
120 seats
Step-by-step explanation:
Total seats in the hall = 300
Percentage of filled seats = 60 %
Number of seats filled = (60 / 100) 300
= 60 * 3
= 180
Therefore, number of empty seats = 300 - 180
= 120

Which function has a domain of x greater-than-or-equal-to 5and a range of y less-than-or-equal-to 3?
y = StartRoot x minus 5 EndRoot + 3
y = StartRoot x + 5 EndRoot minus 3
y = negative StartRoot x minus 5 EndRoot + 3
y = negative StartRoot x + 5 EndRoot minus 3
Answer:
The function that has a domain of 'x' greater-than-or-equal-to 5 and a range of 'y' less-than-or-equal-to 3 is;
[tex]y = -\sqrt{x - 5} +3[/tex].
Step-by-step explanation:
The domain of a function are the possible 'x' values of the function
The range of a function are the possible 'y' values of the function
The given possible functions are;
1) [tex]y = \sqrt{x - 5} +3[/tex]
The range of values for the above function are;
Domain; x ≥ 5
Range; y ≥ 3
2) [tex]y = \sqrt{x + 5} -3[/tex]
The range of values for the above function are;
Domain; x ≥ -5
Range; y ≥ -3
3) [tex]y = -\sqrt{x - 5} +3[/tex]
The range of values for the above function are;
Domain; x ≥ 5
Range; y ≤ 3
4) [tex]y = -\sqrt{x + 5} -3[/tex]
The range of values for the above function are;
Domain; x ≥ -5
Range; y ≤ -3
Therefore, the required function is the third function, [tex]y = -\sqrt{x - 5} +3[/tex].

D. 79
Answer:
Step-by-step explanation:
Answer:
15
Step-by-step explanation:
I am not sure about it, but maybe 15.
<1 = (2x + 5) and <2 = (3x - 10)
<1 = (2 × 15 + 5 ) and <2 = (3 × 15 - 10)
<1 = (30 + 5) and <2 = (45 - 10)
<1 = 35 and <2 = 35

Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4) what is the range?
Answer:
{(0, 5), (-16, -1), (12, 4)}
Step-by-step explanation:
Given the coordinate transformation f(x, y) = (- 2x, y) and the domain (0, 5), (8, - 1) and (- 6, 4), to get the range, we will get f(x, y) for all the domain values
For the coordinate (0,5);
f(0, 5) = (-2(0), 5)
f(0, 5) = (0, 5)
For the coordinate (8, -1);
f(8, -1) = (-2(8), -1)
f(8, -1) = (-16, -1)
For the coordinate (-6, 4);
f(-6, 4) = (-2(-6), 4)
f(0, 5) = (12, 4)
Hence the range is {(0, 5), (-16, -1), (12, 4)}

Write an equation and solve for x.
Answer:
x = 22
Step-by-step explanation:
All the sides are equal. So, it is and equilateral triangle and so all the angles will be equal.
Each angle of equilateral angle = 180/3 = 60
3x - 6 = 60 {Add 6 to both sides}
3x = 60 +6
3x = 66 {Divide both sides by 3}
x = 66/3
x = 22

The graph of a linear inequality in two variables is the __________ containing all of its solutions.
.line
.half-plane
.parabola
.ellipse
Answer:
half-plane
Step-by-step explanation:
To draw the line of a linear inequality, we are going to draw a line that divides the coordinate plane into two parts.
Now, while the solution of the inequality lies on a part of the line, the second part of the line does not represent this solution.
Hence, we have a division into two planes. The shaded plane will represent solution to the inequality while the unshaded part will represent the part that is not a solution.
This depends on the sign of the inequality that is present .
The graph of a linear inequality in two variables is the half plain containing all of its solutions.
The graph of an inequality in two variables is the set of points that represents all solutions to the inequality.
