Answer:
Cost chicken sandwich is $2.35
Cost of ham sandwich is $2.65
Step-by-step explanation:
Let the cost of chicken sandwiches = c
Let the cost of ham sandwiches = h
Number of chicken sandwiches = 6
Number of ham sandwiches = 6
So,
6c + 6h = 30 ------ (I)
Number of chicken sandwiches on second round = 4
Number of ham sandwiches on second round = 8
4c + 8h = 30.6 ------ (ii)
We have two sets of of equations, let us solve;
6c + 6h = 30 ------ (I)
4c + 8h = 30.6 ------ (ii)
From equation i, divide through by 6 to give;
c + h = 5
c = 5 - h
Input into equation ii;
4(5 - h) + 8h = 30.6
20 - 4h + 8h = 30.6
4h = 30.6 - 20
4h = 10.6
h = 2.65
Price of ham sandwich = $2.65
Now, for the chicken sandwich;
c = 5 - 2.65 = $2.35
Cost chicken sandwich is $2.35
Cost of ham sandwich is $2.65
Determine the area under the standard normal curve that lies to the right of the z-score of 1.44. (Use a four-digit decimal. No rounding necessary.)
Answer:
The area is 0.0749
Step-by-step explanation:
The area under the standard normal curve represents probability and has a total value of 1
Now, to the right of the z-score 1.44, the area we are considering is the probability below;
P( z > 1.44)
To get this value, we need to use the standard normal distribution table
Checking this, the probability is
P( z > 1.44) = ) = 0.074934 which is 0.0749 for a four decimal digit
I have to do step by step why the answer of (5x - 1) (5x - 1) is 25x^2 - 10x + 1.
How do i do it?
(5x - 1) (5x - 1)
Ans: 25x^2 - 10x + 1
Answer:
Step-by-step explanation:
(5x - 1) (5x - 1)
= [tex](5x - 1)^{2}[/tex]
Using laws of exponents,
[tex](a - b)^{2} = a^{2} - 2ab + b^{2}[/tex]
here, a = 5x, b = 1
so it becomes,
[tex]5x^{2}[/tex] - 2 × 5x × 1 + [tex]1^{2}[/tex]
[tex]25x^{2}[/tex] - 10x + 1

△ABC and △CDE similar right triangles. The coordinates of all the vertices are integers.
A: The relationship between the slope of AC¯¯¯¯¯ and the slope of CE¯¯¯¯¯ cannot be determined, because the triangles are congruent.
B:The slope of AC¯¯¯¯¯ is equal to the slope of CE¯¯¯¯¯ . This this because ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is the same for AC¯¯¯¯¯ as for CE¯¯¯¯¯
C:The slope of AC¯¯¯¯¯ is greater than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is greater for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .
D:The slope of AC¯¯¯¯¯ is less than the slope of CE¯¯¯¯¯ . This is because the ratio of the change in y-values of the endpoints to the change in x-values of the endpoints is less for AC¯¯¯¯¯ than for CE¯¯¯¯¯ .
Answer:
Option B.
Step-by-step explanation:
Slope of the line AC = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]
= [tex]\frac{\text{AB}}{\text{BC}}[/tex]
= [tex]\frac{4}{6}[/tex]
= [tex]\frac{2}{3}[/tex]
Slope of the line CE = [tex]\frac{\text{DC}}{\text{DE}}[/tex]
= [tex]\frac{2}{3}[/tex]
Therefore, slope of the line AC = Slope of the line AC
And this is because ratio of change in y-values of the endpoints to the change in x-values of the endpoints is the same for AC as for CE.
Option B. is the answer.
Find the slope of the line that passes through
the two given points: (2, 3) and (6, -13)
Answer:
-4
Step-by-step explanation:
-13-3=-16
6-2=4
-16/4=-4
Step-by-step explanation:
Hey there!
The points are; (2,3) as (X1,y1) and (6,-13) as (x2,y2)
Use the formula for slope.
[tex]slope(m) = \frac{y2 - y1}{x2 - x1} [/tex]
Put all values.
[tex]m = \frac{ - 13 - 3}{6 - 2} [/tex]
Simplify it to get answer.
[tex]m = \frac{ - 16}{4} [/tex]
Therefore, slope(m) = -4.
Hope it helps....

Brice has $30 to take his brother and his friends to the movies. If each ticket costs $4.00, and he must buy tickets for himself and his brother, what is the
greatest number of friends he can invite?
Answer:
5 friends
Step-by-step explanation:
beacuse it costs $8.00 for himself and his brother, and he can only invite 5 friends because $30 - $8 is $22
so $22 divided by 4 is 5
Answer:
5
Step-by-step explanation:
You start with $30, and each ticket cost $4.
You have to buy AT LEAST 2 tickets for Brice (yourself in the story) and Brice's brother. That 30-8=22.
22/4=5 (without going over 22)

This graph represents −x−2y=−4 .
Which ordered pair is in the solution set of −x−2y≤−4 ?
A. (−4, 1)
B. (−1, 4)
C. (−4, −1)
D. (4, −1)
Answer:
B
Step-by-step explanation:
We have the equation [tex]-x-2y=-4[/tex] and we want to find which ordered pair is in the solution [tex]-x-2y\leq -4[/tex]
First, let's convert the inequality to slope-intercept form. So, we have:
[tex]-x-2y\leq-4[/tex]
Add x to both sides:
[tex]-2y\leq x-4[/tex]
Divide both sides by -2. Since we're dividing by a negative, we will flip the sign:
[tex]y\geq- \frac{1}{2}x+2[/tex]
Therefore, our original inequality will be the same as above.
Notice that our y is greater than our equation.
Therefore, the shaded area will lie above our line.
So, any point that falls within the region above our line (in the graph) and on the line is a solution to our inequality.
(-4, 1) is below our line, so it's not a solution.
(-1, 4) is above our line. So, (-1, 4) is our answer.
(-4, -1) is again below our line. So, it's not a solution.
Finally, (4, -1) is also below our line, so it's not a solution.
Therefore, our final solution is B: (-1, 4).
Let's check this. Substitute -1 for x and 4 for y. This yields:
[tex]-(-1)-2(4)\stackrel{?}{\leq}4[/tex]
Multiply:
[tex]1-8\stackrel{?}{\leq}{4}[/tex]
Subtract:
[tex]-7\stackrel{\checkmark}{\leq}4[/tex]
So, (-1, 4) is indeed our solution.
And we're done!

Chase drew a scale drawing of a community college. A building at the college, which is 260 meters long in real life, is 286 millimeters long in the drawing. what scale did chase use?
Given parameters:
Actual length = 260m
Drawing length = 286mm
Unknown:
Scale used = ?
Solution:
A scale compares drawing length to ground distance;
To find the scale,
Express the two quantities in the same unit;
actual length = 260 x 10⁻³m = 0.26mm
Now;
drawing length : actual length
286mm : 260 x 10⁻³mm
divide by 286;
1mm on drawing : 9 x 10⁻⁴mm on map
or;
1mm on drawing is 0.9m on ground

HELP ME PLEASE !!!!!
Answer:
C (and D)
Step-by-step explanation:
The multiplication property of equality says the value of the variable is unchanged when both sides of the equation are multiplied by the same value.
In A, no property of equality is involved. The two equations are for different lines.
In B, the subtraction property of equality is used to subtract 9 from both sides of the equation.
In C, the multiplication property of equality is used to multiply both sides of the equation by 3.
In D, the division property of equality is used to divide both sides of the equation by 5. (This is equivalent to using the multiplication property to multiply both sides of the equation by 1/5.)

If you're allowed one choice, the best selection is C. If multiple choices are allowed, both C and D are correct answers.
