Answer:
Number of chicken sandwiches = 150
Number of turkey sandwiches = 150
Number of roast beef sandwiches= 100
Step-by-step explanation:
We are told the school cafeteriat makes and sells 3 different types of sandwiches which are; chicken, turkey and roast beef.
Let chicken be x, turkey be y and roast beef be z.
We are told they make 400 sandwiches in total.
Thus;
x + y + z = 400
However, we are told that the cafeteria makes same number of chicken and turkey sandwiches.
Thus, x = y
Thus;
Total is now;
x + x + z = 400
2x + z = 400 - - - (eq 1)
Now,we are told that chicken, turkey and roast beef sandwiches are sold for $3, $3.5 and $4 respectively. Also that the total amount realized from sales is $1375.
Thus;
3x + 3.5y + 4z = 1375
Since x = y. Thus;
3x + 3.5x + 4z = 1375
6.5x + 4z = 1375 - - - (eq 2)
Let's make z the subject in eq 1.
Thus;
z = 400 - 2x - - - (eq 3)
Putting 400 - 2x for z in eq(2) gives us;
6.5x + 4(400 - 2x) = 1375
6.5x + 1600 - 8x = 1375
1600 - 1375 = 8x - 6.5x
225 = 1.5x
x = 225/1.5
x = 150
Putting 150 for x in eq 3 gives;
z = 400 - 2(150)
z = 400 - 300
z = 100
Since x = y. Then y = 150

find the equation of the line shown
Answer:
y = 1/2x
Step-by-step explanation:
The equation of the straight line shown in the graph is y = 2x.
How to represent a straight line on a graph?To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.
From the given graph, the points the straight line is passing through can be found as (2, 1) and (4, 2).
The equation of the line for the given points can be written as follows,
(4 - 2)/(2 - 1) = (y - 2)/(x - 1)
=> y - 2 = 2(x - 1)
=> y = 2x - 2 + 2
=> y = 2x
Hence, the equation of the straight line shown in the graph is y = 2x.

1.25c + 12 = 2 ( change 5/4 to a decimal for easy understading)
1.25c + 12 - 12 = 2 - 12 ( isolate the variable rememebr whatever you do to the right do it to the left )
1.25c = -10
1.25c / 1.25 = -10 / 1.25 (divide both sides by 1.25 )

and m\angle B=(2x+19)^{\circ}∠B=(2x+19)

, then find the value of x.
Answer:
x = 8
Step-by-step explanation:
Since the angles are vertical then they are congruent, thus
5x - 5 = 2x + 19 ( subtract 2x from both sides )
3x - 5 = 19 ( add 5 to both sides )
3x = 24 ( divide both sides by 3 )
x = 8

5x - 5 = 2x + 19
3x - 5 = 19

To find the area of parallelogram RSTU, Juan starts by drawing a rectangle around it. Each vertex of parallelogram RSTU is on a side of the rectangle he draws. On a coordinate plane, parallelogram R S T U has points (negative 4, negative 3,) (negative 5, 1), (4, 3), and (5, negative 1). Which expression can be subtracted from the area of the rectangle to find the area of parallelogram RSTU? 2 (18 + 4) One-half (18 + 4) (18 + 4) (18 - 4)
Answer:
The value that can be subtracted from the area of the rectangle to give the area of the parallelogram = 1/2 × 4.1245 × 0.1085
Step-by-step explanation:
The given parameters are;
The coordinates of parallelogram RSTU are;
R(-4, -3), S(-5, 1), T(4, 3), U(5, -1)
The lengths of the sides are (using an online length calculator);
RS = 4.1231
RT = 10
ST = 9.2195
SU = 10.198
TU = 4.1231
UR = 9.2195
Therefore, by definition of a parallelogram, we have;
RS║TU and ST║UR
The slope of RS = (1 - (-3))/(-5 - (-4)) = -4
The slope of ST = (3 - 1)/(4 - (-5)) = 2/9
The equation of the line perpendicular to ST is therefore;
y - 1 = -9/2×(x - (-5))
y = -9x/2 - 43/2
The equation of RS = y - (-3) = 1/4×(x - (-4)) = x/4 + 1
y = x/4 - 2
The point where the two lines meet is therefore;
-9x/2 - 43/2 = x/4 - 2
x = -78/19
y = -115/38
The length of the side of the rectangle = 4.1245
The excess width of the rectangle = 0.1085
The value that can be subtracted from the area of the rectangle to give the area of the parallelogram = 1/2 × 4.1245 × 0.1085.

Plss help!!Need this ASAP!!Daniel began filling an empty swimming pool
at 8:00 AM. After 5 hours, the pool contained
230 gallons of water. If the water input continues
at a constant rate, how many more hours are
needed to completely fill the 920-gallon pool?
Answer:
15 hours
Step-by-step explanation:
To find the gallons per hour: 230/5=46, this means that it take 46 gallons per hour, you add 46 to 230, and you do that 15 times and you'll get 920. The pool will be filled at 11:00 pm.
Simplify the expression.

A 3-column table with 4 rows. Column 1 is labeled Inequality with entries 8 greater-than 2, negative 10 less-than negative 5, 16 greater-than negative 40, negative 8 less-than 4. Column 2 is labeled Multiply each side by: with entries negative 2, 5, 8, negative 4. Column 3 is labeled New Inequality with entries A, B, C, D. The table gives an inequality and a number to divide both sides of the inequality by. Identify the new, true inequality. A: B: C: D: The inequality symbol is only reversed when dividing by a number.
Answer:
A:
✔ –16 < –4
B:
✔ 40 > 8
C:
✔ –45 < 15
D:
✔ 35 > –20

Deepak is measuring sides and angles of triangle FGH to determine whether it is congruent to triangle MNP shown below. Triangle M N P. Side P N is 26.7 centimeters, side M N is 18.3 centimeters, and side P M is 14.2 centimeters. Angle P is 40 degrees, angle N is 30 degrees, and angle M is 110 degrees. Deepak found that Angle G has a measure of 50° and Segment F H is 18.3 centimeters long. Does he need to continue measuring sides and angles of triangle FGH and why? No, he knows that the triangles are congruent because there are corresponding sides and angles that are congruent. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP. Yes, he must verify that the other two side lengths and the other two angle measures are the same as those found in triangle MNP. Yes, he must only verify that the other two angle measures are the same as those found in triangle MNP.
Answer:
B. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP.
Step-by-step explanation:
I took the test.
The correct option is B. No, he knows that the triangles are not congruent because those measurements are not equal to the corresponding parts of triangle MNP.
What is the congruent triangle?Two triangles are said to be congruent if the length of the sides is equal, a measure of the angles are equal and they can be superimposed.
We are given that Deepak is measuring sides and angles of triangle FGH to determine whether it is congruent to triangle MNP,
In Triangle M N P.
Side P N = 26.7 centimeters,
M N is 18.3 centimeters,
P M is 14.2 centimeters.
Angle P is 40 degrees, angle N is 30 degrees, and angle M is 110 degrees.
He found that Angle G has a measure of 50° and Segment F H is 18.3 centimeters long.
Based on the definition, two triangles are congruent if the three sides are equal and the three angles are equal.
Hence, he need to know the other lengths of the sides of the triangle and the others angles to know if they are congruent or not.

3. Volunteer drivers are needed to bring 80 students to the championship baseball
game. Drivers either have cars, which can seat 4 students, or vans, which can seat 6
students. The equation 40 + 6v = 80 describes the relationship between the number
of cars, c, and number of vans, v, that can transport exactly 80 students.
Select all statements that are true about the situation.
A. If 12 cars go, then 2 vans are needed.
B. c = 14 and v= 4 are a pair of solutions to the equation.
C. If 6 cars go and 11 vans go, there will be extra space.
D. 10 cars and 8 vans isn't enough to transport all the students.
E. If 20 cars go, no vans are needed.
F. 8 vans and 8 cars are numbers that meet the constraints in this situation.
Answer:
Options (B), (C) and (E) are the correct options.
Step-by-step explanation:
Equation that represents relation between the number of cars c and the number of vans v to transport 80 students is,
4c + 6v = 80
Option A.
If c = 12,
4(12) + 6(v) = 80
48 + 6v = 80
6v = 32
[tex]v=\frac{16}{3}[/tex]
Which is not equal to 2.
Therefore, Option A is incorrect.
Option B
If c = 14,
4(14) + 6(v) = 80
56 + 6v = 80
6v = 24
v = 4
Therefore, c = 14 and v = 4 is a pair of solutions.
Option B is correct.
Option C.
If c = 6 and v = 11
4(6) + 6(11) = 24 + 66
= 90
This means with 6 cars and 11 vans 90 students can be transported. Therefore, there will be extra space.
Option C is correct.
Option D.
If c = 10 and v = 8
4(10) + 6(8) = 40 + 48
= 88
Therefore, 10 cars and 8 vans are enough to transport 80 students.
So option D is incorrect.
Option E.
If c = 20,
4(20) + 6(v) = 80
80 + 6v = 80
v = 0
Therefore, for 20 cars go no vans are needed.
Option E is correct.
Option F.
Constraints in this situation,
Minimum number of cars to be used = 20
c ≥ 20
Minimum number of vans to be used = [tex]\frac{80}{6}[/tex] ≈ 14
v ≥ 14
Therefore, Option (F) is incorrect.
