Answer:
C = 600 + 50s
Step-by-step explanation:
The students are planning to visits the Canada's wonderland. The students will spend a full day at the park.
The entry fee for each student is $50 and the bus cost is $600. Each student will pay $50 for entry into the park.
Let
the number of student = s
cost of the trip = C
Relating the variable C and s
The total amount of money the student will pay for entry fee = 50 × s = 50s
Therefore, cost of the trip can be expressed as follows
C = 600 + 50s
Which one of the following gives the gradient of the line shown above?
A: 3/2
B: -2/3
C: 2/3
D: 6
E: -3/2
Answer: A: 3/2
Step-by-step explanation:
When we have a line that passes through the points (x1, y1) and (x2, y2), the slope of this line is:
s = (y2 - y1)/(x2 - x1)
In this graph we can see that the line passes through the points:
(0, - 3) and (2, 0)
Then the slope is:
s = (0 - (-3))/(2 -0) = 3/2
Then the correct option is A.
The gradient of the line shown above is A: [tex]\frac{3}{2}[/tex]
Slope of the line that passes through two points [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] is :
slope [tex]=\frac{(y_2 - y_1)}{(x_2 - x_1)}[/tex]
Now, from the given graph we can see that the line passes through the points:
(0, - 3) and (2, 0)
The slope is:
[tex]s = \frac{(0 - (-3))}{(2 -0)} \\=\frac{3}{2}[/tex]
Therefore the correct option is A.

Help pls!!! The diagram shows a 12 cm * 3 cm * 4 cm cuboid. Find angle GEC. Give your answer to 1 decimal place.
Answer:
m<GEC = 17.9 deg
Step-by-step explanation:
First, use the Pythagorean theorem to find the length of GE.
(GE)^2 = (E?)^2 + (?G)^2
I am using ? in place of the front right corner point name that is not visible.
(GE)^2 = 12^2 + 3^2
GE = 12.3693
In triangle EGC, for angle GEC, GE is the adjacent leg, and GC is the opposite leg. We use the tangent.
tan GEC = opp/adj
tan GEC = GC/GE
tan GEC = 4/12.3693
tan GEC = 0.32338
Use inverse tangent to find the angle.
m<GEC = 17.9 deg
The angle ∠GEC of a cuboid will be:
"17.9°"
Pythagoras TheoremAccording to the question,
Three dimensions,
AC = 4 cm
EH = 12 cm
GH = 3 cm
By using Pythagoras theorem,
→ (GE)² = (EH)² + (GH)²
By substituting the values,
= (12)² + (3)²
= 144 + 9
= 153
GE = √153
= 12.3693
Now, In ΔEGC
here, Adjacent leg = GE
Opposite leg = GC
→ tan GEC = [tex]\frac{Opposite}{Adjacent}[/tex]
= [tex]\frac{GC}{GE}[/tex]
= [tex]\frac{4}{12.3693}[/tex]
= 0.32338
Hence, by using inversing tangent
m∠GEC = 17.9°
Thus the above answer is correct.

The temperature of a city changed by -20°C over a four week. If the temperature changed by the same amount each week write an expression to show the average change in the temperature of the week simplify the expression and explain using words what your answer means
Answer:
A) [tex]T=\frac{-20}{4}[/tex]
B) T = -5 °C
Step-by-step explanation:
A) Let T be the change in temperature of the week. T is determined as the total temperature change (-20°C) divided by the number of weeks that have passed (4 weeks). The expression is:
[tex]T=\frac{-20}{4}[/tex]
B) In order to simplify the expression, simply perform the division.
[tex]T=\frac{-20}{4}\\T=-5^oC[/tex]
This means that the temperature has dropped by 5 degrees each week.

Answer:
Step 3
Step-by-step explanation:
The solution is given in the image attached. The steps are:
Step 1:
[tex]2x-\frac{1}{4} -\frac{3}{5}x=\frac{55}{4}[/tex]
Step 2: simplifying the coefficients of x:
[tex]2x -\frac{3}{5}x-\frac{1}{4}=\frac{55}{4}\\\frac{10x-3}{5} -\frac{1}{4}=\frac{55}{4}\\\frac{7x}{5} -\frac{1}{4}=\frac{55}{4}[/tex]
Step 3: Adding 1/4 to both sides
[tex]\frac{7x}{5} -\frac{1}{4}+\frac{1}{4} =\frac{55}{4}+\frac{1}{4}\\ \frac{7x}{5}=\frac{55+1}{4}\\ \frac{7x}{5}=\frac{56}{4}\\[/tex]
Step 4: Multiplying both sides by 5/7
[tex]\frac{7x}{5}*\frac{5}{7} =\frac{56}{4}*\frac{5}{7} \\x=10[/tex]

The principal represents an amount of money deposited in a savings account subject to compound interest of a given rate.How much money there will be in the account after the given number of years. The principal is$5000, 5% Rate, quarterlybover a two year period.
Answer:
$5522.43
Step-by-step explanation:
The amount in an account for a principal P saved at compound interest for a duration of n years compounded with period k at an annual interest rate of r% is calculated using the formula:
[tex]A(n)=P(1+\frac{r}{k})^{nk}[/tex]
In this case:
Principal, P=$5000Interest Rate, r=5%=0.05Time, n=2 yearsPeriod, k=4(Quarterly)Therefore, the amount is:
[tex]A(n)=5000(1+\frac{0.05}{4})^{4*2}\\=5000(1+0.0125)^{8}\\=5000(1.0125)^{8}\\=\$5522.43[/tex]

In option A, there are 9 red boxes and 3 blue boxes
If we simlify,
9 : 3 = 3 : 1 = 1 : 1/3
Hope you understand
Answer: Grid A
Step-by-step explanation:
The ratio red:blue is simplified to 1:1/3.
To make things easier, we can expand it so that both sides add up to 12(total number of squares in a grid).
We can multiply both sides by 9.
1 x 9= 9
1/3 x 9= 3
Now the ratio red:blue is 9:3, which adds up to 12.
Grid A is the only grid where there are 9 red squares and 3 blue squares.

The path of a football kicked by a field goal kicker can be modeled by the equation y = -0.04x2 + 1.56x, where x is the
horizontal distance in yards and y is the corresponding height in yards. What is the approximate maximum height of the
football?
15.21 yd
19.5 yd
38.94 yd
45.63 yd
Answer:
19.5 yd
Step-by-step explanation:
To khown the maximum height we must derivate the function and see when the derivated function equals 0
Let f be our function : f(x)= -0.04x²+1.56x ⇒f'(x)= -0.08x+1.56
f'(x)= 0 ⇒ -0.08x+1.56 =0 ⇒1.56= 0.08 ⇒ x= 1.56/0.08 ⇒ x=19.5 so the maximum height is 19.5 yd

Answer: y = 6
Step-by-step explanation:
A square's area can be done by using s^2, where s is y in this case. Because there are 5 squares, the area of the figure is 5y^2. Because the area is also 180cm, 5y^2=180.
Then divide both sides of the equation by 5 to get y^2 = 36. Then square root both sides of the equation to get y = 6.

In an effort to cut costs and improve profits, any US companies have been turning to outsourcing. In fact, according to Purchasing magazine, 54% of companies surveyed outsourced some part of their manufacturing process in the past two to three years. Suppose 555 of these companies are contacted. What is the probability percentage that 338 or more companies outsourced some part of their manufacturing process in the past two or three years? Round the percent to two decimal places.
Answer:
Step-by-step explanation:
This is a binomial probability distribution because there re only 2 possible outcomes. It is either a surveyed company outsourced some part of their manufacturing process in the past two to three years. The probability of success, p would be that a randomly selected company x, outsourced some part of their manufacturing process in the past two to three years. From the information given, p = 54/100 = 0.54
Number of success, x = 338
Number of samples, n = 555
We want to determine the probability that 338 or more companies outsourced some part of their manufacturing process in the past two or three years which is expressed as
P(x ≥ 338)
From the binomial probability calculator,
P(x ≥ 338) = 0.0006
The percentage is 0.0006 × 100 = 0.06%

explanation: I got this right
The two pink diagrams in the given figure are parallelograms.
What is a parallelogram?A unique kind of parallelogram created with parallel lines is called a parallelogram.
A parallelogram can have whatever angle between its neighboring sides, but for it to be a parallelogram, it's opposite sides must be parallel. If a quadrilateral's opposite sides are parallel and congruent, it will be a parallelogram.
So a rectangle both with pairs of separate sides being parallel and equal is known as a parallelogram.
The word "parallelogram" is a translation of the Greek term "parallelogrammon," which means "confined by line segments." As a result, a quadrilateral that is surrounded by parallel lines is called a parallelogram.

a) For every section of the graph as x goes up 1, y does down 4. It has a proportional relationship and you can use the rise and run found to do rise/run and get a slope of -4 and when x is at 0, y is at 2, giving you a y-intercept of 2.
