note: enter your answer and show all the steps that you use to solve this problem in the space provided. write and solve an equation that represents the following situation: 35 people paid a total of $245 for admission to a local soccer game. what is the price of admission?
The price of each admission is 7
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given:
Total amount paid for admission = $245
Total number of people=35
So,
let the price of admission be x
So, 35x= 245
Now dividing both side by 35
35x/35=245/35
x= 7
Hence, price of each admission is 7.

Answer:
[0, ∞)
Step-by-step explanation:
The domain is the x values in a function. As you can see from the graph, the function touches zero (touching meaning the value zero is bracketed) and goes to infinity (infinity is parenthesis).
If a value is included it is bracketed. If it is not included it is used with parenthesis (infinity cannot be reached to it is used with parenthesis).

A company is manufacturing computer monitors that are 22 inches wide, 22 inches across, and 2 inches thick. If the average cost to produce a computer monitor is $0.43 per cubic inch, then about how much would it cost the company to make 10 computer monitors?
Answer:
$4162.4
Step-by-step explanation:
As per the question statement,
The computer monitors are in cuboid structure.
Width of computer monitors = 22 inches
Length of computer monitors = 22 inches
Thickness of computer monitors = 2 inches
Average cost of production per cubic inch = $0.43
To find:
Cost to the company to make 10 monitors.
Solution:
Volume of a cuboid is given as following:
[tex]Volume = Length \times Width \times Height[/tex]
Volume of one computer monitor as per the given dimensions = [tex]22\times 22 \times 2[/tex] = 968 cubic inches
Volume of 10 such monitors = 968 [tex]\times[/tex] 10 = 9680 cubic inches
Cost of manufacturing of 1 cubic inch = $0.43
Cost of manufacturing of 9680 cubic inch = $0.43 [tex]\times[/tex] 9680 = $4162.4

The senior class plans a school trip to Washington DC. Students should bring money for meals and
souvenirs. They are told to bring at least $60 but no more than $135. Write a compound inequality that
represents the amounts of money a student can bring.
Answer:
$65 ≤ x ≤ $135
Step-by-step explanation:
Now, one should know the meaning of compound inequality. A compound inequality is an inequality that simply combines the two simple inequalities.
Now, in an inequality, three relations are performed, equal to, less than, and greater than. You can combine 'equal to' with 'less than' or 'greater than' according to the situation given.
Notice that in the given sign
≤
the value on the left side of the pointed side will be small or lesser than the value on the right side. Also notify that if inverted, like this ≥
The value of the left side will be greater. This means the value at the pointed side will always be smaller. The lower bar is a sign of equal to
if this is written
x ≤ 3
It means that x can be equal to three or any value less than 3 means 2,1,0,-1, etc.
Now in the question given, it is stated that money should be not less than $65 means it can either be $65 or more but not less than it. Let's assume 'x' as the amount required,
So one inequality is
$65 ≤ x
The second condition which is amount should be no more than $135, means it can be $135 or less, so inequality is
x ≤ $135
Remember that we use AND in the answer because both statements of inequality need to be fulfilled or satisfied.

Answer:
slope: 20/3 parallel
Step-by-step explanation:
y1-y2/x1-x2 gives you slope(30--10/12-6). Plot the points, create line segments, you'll find that they are parallel.
Answer:
1. 6[tex]\frac{2}{3}[/tex]
2. Parallel
Step-by-step explanation:
To find the slope, you need to find the [tex]\frac{rise}{run}[/tex] between two points.
[tex]\frac{rise}{run}[/tex] = [tex]\frac{30-(-10)}{12-6}[/tex]
= [tex]\frac{40}{6}[/tex]
= 6[tex]\frac{2}{3}[/tex]
If a graph has more than a point on the y-axis even though the x-axis remains the same, it means that it is a vertical line. Since Graph 1 has (-1) on the x-axis but there are two points on the y-axis, 4 & (-9), it is a vertical graph. Since Graph 2 has (11) on the x-axis but there are two points on the y-axis, (-2) & 6, it is also a vertical graph. Thus, both graphs are parallel.
What is the volume of this pyramid???????
Answer:
Step-by-step explanation:
A of base: l ×w =5×4=20cmsquared
Missing length of c=a+b=c
C=6+2
C=8cm
A of side 1= b×h÷2 ×2
= 5×8÷2×2
= 40 ÷2×2
=20 ×2
= 40 cm squared
A of side 2= b×h÷2×2
= 4×8÷2×2
= 32 ÷ 2 ×2
= 16 ×2
= 32cm squared
Total of pyramid is = area of base + A
off side 1 + A if side 2
=92 cm cubed

The measure of angle B is 70°.
The measure of angle C is (4x)°.
What is the value of x?
Enter your answer in the box.
x =
Answer:
x=20
Step-by-step explanation:
By the Triangle Sum Theorem, the angles of a triangle add up to 180. So we can set up the equation like this:
2x-10+70+4x=180
Combine Like terms
6x+60=180
Subtract 60 from both sides
6x=120
Divide by 6 to isolate the variable
x=20
Answer:x= 20
Step-by-step explanation:
As the equation of three angles of a triangle is 180°,
Then, 2x-10+70+4x=180
6x=120
So,x= 20
please help asapp!!!?!!?!?!?
Step-by-step explanation:
the sum of interior angles in a triangle is 180°
so
2x+2+12x-8+6x+6=180
20x=180
x=180/20=9
so
m<A =6x+6=6*9+6=54+6=60
m<M=12x-8=12*9-8=100
m<N=2x+2=2*9+2=18+2=20
MAN is an obtuse triangle
because of 100° angle
question 4
isosceles
HELPPPPPP PLEASEEEEE !!!!!
Answer:
m∠DBC is 43°
Step-by-step explanation:
Let us solve the question
∵ D is in the interior of ∠ABC
→ That means D divides ∠ABC into two angles ABD and DBC
∴ m∠ABD + m∠DBC = m∠ABC
∵ m∠ABD = (3x + 5)°
∵ m∠DBC = (5x - 7)°
∵ m∠ABC = 78°
→ Substitute them in the equation above
∴ 3x + 5 + 5x - 7 = 78
→ Add the like terms in the left side
∵ (3x + 5x) + (5 + -7) = 78
∴ 8x + -2 = 78
∴ 8x - 2 = 78
→ Add 2 to both sides
∴ 8x -2 + 2 = 78 + 2
∴ 8x = 80
→ Divide both sides by 8
∴ x = 10
→ To find m∠DBC, substitute x by 10 in its measure
∵ m∠DBC = 5(10) - 7
∴ m∠DBC = 50 - 7
∴ m∠DBC = 43°

Answer:
it's 42 my bad...
Step-by-step explanation:
Answer:
Choice C 42 in^2
Step-by-step explanation:
Area of a triangle= 1/2(b)(h)
= 1/2(3)(6)
= 9
Since there is two triangles we can do:
9(2) = 18
Area of a rectangle = (b)(h)
= (4)(6)
= 24
24+18 = 42 in^2
In the following expression, 7x +15, what is the 7?
A. coefficient
B. term
C. constant
D. variable
Answer:
A. coefficient
Step-by-step explanation:
A constant is the number that isn't with any variable, which in this case, the constant would be 15.
A variable is a unknown value, which in this case, the variable would be x.
The term are the numbers in the equation, which in this case, the terms would be 7x and 15.
The 7 in the expression 7x + 15 is the coefficient.
The correct option is A.
What is an expression?A term is composed of one mathematical expression. A single variable (a letter), a single integer (positive or negative), or a number of variables that have been multiplied but never added or subtracted are all examples of single variables. There is a number in front of certain words that are variables. A word or phrase is preceded by a coefficient.
In general, a coefficient is the numerical factor of a term that contains a variable. In this case, the term containing the variable x is 7x, and the coefficient of this term is 7. The term 15 is a constant term, which is a term that does not contain any variables.

Answer:
$1,377
Step-by-step explanation:
the way that I did it-
100-25=75
1700x0.75=1275
8%=0.08, just add a 1 to the sales tax whenever you are calculating that.
1275x1.08=1377
therefore it is $1,377

Solve for linear equations by substitution
x + 2y = 6
X-y=3
Answer:
Let's solve your system by substitution.
x+2y=6;x−y=3
Step: Solvex+2y=6for x:
x+2y=6
x+2y+−2y=6+−2y(Add -2y to both sides)
x=−2y+6
Step: Substitute−2y+6forxinx−y=3:
x−y=3
−2y+6−y=3
−3y+6=3(Simplify both sides of the equation)
−3y+6+−6=3+−6(Add -6 to both sides)
−3y=−3
−3y
