Answer:
Children = 51
Adults = 42
Students= 84
Step-by-step explanation:
Children = $2
Students = $3
Adults = $4
Total sales = $522
Total people who attended = 177
Adults =a
Students = s= 2a
Children = c
c+s+a = 177 (1)
2c+3s+4a=522 (2)
Substitute s=2a into the equations
c + 2a + a = 177
c + 3a = 177 (3)
2c + 3(2a) + 4a = 522
2c + 6a + 4a = 522
2c + 10a = 522 (4)
c + 3a = 177 (3)
2c + 10a = 522 (4)
Multiply (3) by 2
2c + 6a = 354 (3b)
2c + 10a = 522
Subtract (3b) from (4)
10a - 6a = 522 - 354
4a = 168
Divide both sides by 4
a= 168/4
= 42
a= 42
s= 2a
= 2(42)
= 84
s= 84
Substitute the value of s and a into (1)
c+s+a = 177 (1)
c + 84 + 42 = 177
c + 126 = 177
c = 177 - 126
= 51
c=51
Children = 51
Adults = 42
Students= 84

They are allowed to use the computer from 4 p.m. to 10 p.m. Each sister can use the computer for at most minutes each night. In terms of the greatest number of hours and the minutes remaining, each sister can use the computer for at most hour(s) and minute(s) each night. Please hurry!!!!
Answer:
1.5 hours
Step-by-step explanation:
there are 6 hours in between the times of 4 and 10
so 4 sister split up 6 hours equally
to do this, we divide 6 and 4
6/4 = 1.5 hours
each sister can spend 1.5 hours on the computer
Answer:
1 hour and 30 minutes
Step-by-step explanation:
If four sisters get 1 hour each, 2 hours are left.
4 half hours make 2 hours.

Write a function g whose graph represents a reflection in the x-axis of the graph of f(x)=1/2x-3
Answer: g(x) = -(1/2)*x + 3.
Step-by-step explanation:
First, let's define a reflection over the x-axis.
If we have a point (x, y) and we reflect it over the x-axis, our new point will be (x, -y).
Now, when we have a function
f(x) = y, the points can be written as:
(x, y = f(x) ) = (x, f(x))
Then, after the reflection over the x-axis, we have:
(x, y = g(x)) = (x, -f(x))
So now we have g(x) = -f(x)
and we know that f(x) = (1/2)*x - 3
then our new function is g(x) = y = -f(x) = -( (1/2)*x - 3) = -(1/2)*x + 3.
g(x) = -(1/2)*x + 3.
What are the domain and range of the function f(x)= X-7+9?

Answer:
x = 122
Step-by-step explanation:
Step 1: State what is known
In the picture we can see they marked ∠ABC with a box meaning it is a 90° angle, given that information we can now solve
Step 2: Solve
∠ABC = x - 32
90 = x - 32
90 + 32 = x
122 = x
Therefore 'x' is equal to 122
In the triangle below x=? Round to the nearest tenth
Work Shown:
sin(angle) = opposite/hypotenuse
sin(35) = x/15
15*sin(35) = x
x = 15*sin(35)
x = 8.60364654526569
x = 8.6

4x + 9x + 3 = WILL GIVE BRAINLY, PLUS 20 POINTS.
Answer:
13x + 3
Step-by-step explanation:
Since there is no value on the left, you just have to simplify this. You always add similar variables together, and the constant is a different value, so 4x + 9x would result in 13x. 13x + 3 would be the correct simplified answer.
Answer:
13x+3
Step-by-step explanation:
4x+9x+3
You do not add 13x to 3 because 3 does not have an x
If the numbers 4, 5 and 6 are each used exactly once to replace the letters in the expression A ( B − C ), what is the least possible result?
Answer:
The least possible result is -10.
Step-by-step explanation:
Given the numbers 4, 5 and 6 are to be chosen one of the letters A, B or C.
First of all,
Let A = 4, B = 5 and C = 6
[tex]A(B-C) = 4 \times (5-6) = 4 \times -1 = -4[/tex]
Let A = 4, B = 6 and C = 5
[tex]A(B-C) = 4 \times (6-5) = 4 \times 1 = 4[/tex]
Let A = 5, B =4 and C = 6
[tex]A(B-C) = 5 \times (4-6) = 5 \times -2 = -10[/tex]
Let A = 5, B = 6 and C = 4
[tex]A(B-C) = 4 \times (6-4) = 4 \times 2 = 8[/tex]
Let A = 6, B = 4 and C = 5
[tex]A(B-C) = 6 \times (4-5) = 6 \times -1 = -6[/tex]
Let A = 6, B = 5 and C = 4
[tex]A(B-C) = 6 \times (6-5) = 6 \times 1 = 6[/tex]
Summarizing the above values in the form of a table:
[tex]\begin{center}\begin{tabular}{ c c c c}A & B & C & A(B-C)\\ 4 & 5 & 6 & -4\\ 4 & 6 & 5 & 4\\ 5 & 4 & 6 & -10\\ 5 & 6 & 4 & 10\\ 6 & 4 & 5 & -6\\ 6 & 5 & 4 & 6\end{tabular}\end{center}[/tex]
So, the least possible result is -10.

Find the measure of Angle R if a = 9 square root 2 and b = 18 square root 2.
Please help!!
Answer: ∠TRa = 30°, ∠aRA = 90°, ∠TRA = 120°
Step-by-step explanation:
I'm not sure if you need the angle of the left triangle only (= 30°)
or if you need the the triangle plus the rectangle (= 120°)
Left Triangle (∠TRa)
The hypotenuse is twice the base so it is a 30° - 60° - 90° triangle
where the base corresponds to the 30° angle.
Rectangle (∠aRA)
A rectangle has four right angles --> four 90° angles.
Angle Sum Theorem
∠TRA = ∠TRa + ∠aRA
= 30° + 90°
= 120°

What description below represents the pattern?
Step-by-step explanation:
In my opinion this pattern is adding 2 boxes each time
name a pair of corresponding angles
name a pair of alternate interior angles
name a pair of alternate exterior angles
name a pair of same-side interior angles
They are on the same side of the transversal cut (both to the left of the transversal) and they are both above the two black lines. It might help to make those two black lines to be parallel, though this is optional.
Other pairs of corresponding angles could be:
angle 2 and angle 6angle 3 and angle 7angle 4 and angle 8=======================================================
Alternate interior angles = angle 3 and angle 5They are between the black lines, so they are interior angles. They are on alternate sides of the blue transversal, making them alternate interior angles.
The other pair of alternate interior angles is angle 4 and angle 6.
=======================================================
Alternate exterior angles = angle 1 and angle 7Similar to alternate interior angles, but now we're outside the black lines. The other pair of alternate exterior angles is angle 2 and angle 8
=======================================================
Same-side interior angles = angle 3 and angle 6The other pair of same-side interior angles is angle 4 and angle 5. They are interior angles, and they are on the same side of the transversal.

Use trig ratios to find the measure of the angle in this Triangle (Image)
Answer:
θ = 36.9°
Step-by-step explanation:
Trigonometric ratios in a right triangle will be,
Sinθ = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex] = [tex]\frac{\text{AC}}{\text{AB}}[/tex]
Cosθ = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex] = [tex]\frac{\text{BC}}{\text{AB}}[/tex]
Tanθ = [tex]\frac{\text{Opposite side}}{\text{Adjacent side}}[/tex] = [tex]\frac{\text{AC}}{\text{BC}}[/tex]
In the picture attached,
Given sides are,
AB = 5 and BC = 4
Therefore, to find the given angle θ only Cosine will be applicable.
Cos θ = [tex]\frac{\text{BC}}{\text{AB}}[/tex]
= [tex]\frac{4}{5}[/tex]
θ = [tex]Cos^{-1}(0.8)[/tex]
θ = 36.87°
θ ≈ 36.9°

Fraiser drew a model of his hometown on the coordinate plane below. Each unit of the coordinate plane represents 1 mile. A grocery store is located at (6, 4) and a school is located at (6, 8). What is the distance between the grocery store and the school?
Answer:
The distance between the grocery store and the school is 4 miles.
Step-by-step explanation:
Given that each point is represented in rectangular form. The staight-line distance ([tex]d[/tex]) between two points on a plane is given by the Pythagorean Theorem:
[tex]d =SF\cdot \sqrt{(x_{B}-x_{A})^{2}+(y_{B}-y_{A})^{2}}[/tex]
Where:
[tex]x_{A}[/tex], [tex]x_{B}[/tex] - Horizontal locations of points A and B, dimensionless.
[tex]y_{A}[/tex], [tex]y_{B}[/tex] - Vertical locations of points A and B, dimensionless.
[tex]SF[/tex] - Scale factor, measured in miles.
If [tex]SF = 1\,mi[/tex], [tex]A = (6, 4)[/tex] and [tex]B = (6,8)[/tex], the straight line distance is:
[tex]d = (1\,mi)\cdot \sqrt{(6-6)^{2}+(8-4)^{2}}[/tex]
[tex]d = 4\,mi[/tex]
The distance between the grocery store and the school is 4 miles.

Answer:
1.1783
Step-by-step explanation:
The attached picture shows a cross section of the cylindrical shell that it is convenient to use as a differential of the volume. The radius from the center of revolution is (1-x), so the circumference of the shell is 2π(1-x). Of course, its height is tan(x), so the differential of volume is ...
dV = 2π(1-x)tan(x)
The indefinite integral does not have a nice closed-form solution, but it can be easily integrated numerically from x = 0 to 1 by most scientific and graphing calculators. The attached shows the volume to be about 1.1783 cubic units.
Find the value of m. A. 32 B. 63 C. 50 D. 74
Answer:
A
Step-by-step explanation:
Tangents drawn to a circle from an external point are congruent, thus
the triangle formed by the 2 tangents is isosceles with base angles of 74°
m = 180° - (74 + 74)° = 180° - 148° = 32° ( sum of angles in Δ )
The value of the measured angle of m is 32°.
What is a Tangent of Circle?A tangent of a circle is defined as a single point where a single straight line touches or intersects the circle. A line that never touches the inside of the circle is called a tangent.
The line connecting the outer point will cut the angle between the tangents in bisect and the center are equal to each other.
According to the given figure as
A circle with center O,
Since there are two tangents to the circle drawn from an external point.
therefore the lengths of tangents drawn from an external point to a circle are equal.
So, the triangle formed by the 2 tangents is isosceles with base angles of 74°
We know that sum of angles in the triangle is 180 degrees
So ∠ m = 180° - (74 + 74)°
⇒ ∠ m = 180° - 148°
⇒ ∠ m = 32°
Hence, the value of the measured angle of m is 32°.
