An adult ticket to the school play cost $14.75. A child ticket cost $5.25. Mr. Montes bought 2 adult tickets and 4 child tickets.
Answer:
$50.50
Step-by-step explanation:
From the above question, we are to find the total cost of the tickets Mr Montes bought
An adult ticket to the school play cost $14.75.
A child ticket cost $5.25.
Mr. Montes bought 2 adult tickets and 4 child tickets.
Hence, the total cost is
= 2 × $14.75 + 4 × 5.25
= $29.5 + $21
= $50.50

Write an equation to model the relationship between the number of weeks, x, and the number of views, f(x).
Enter the correct answer in the box by replacing the values of a and b.
Answer:
a = 5120
b = 1.25
Step-by-step explanation:
Let the exponential function representing the given table is,
f(x) = [tex]a(b)^x[/tex]
Here, f(x) = Number of views
x = Number of weeks
We choose two points from the given table and satisfy the equation of the function.
Let the points are (0, 5120) and (1, 6400)
For a point (0, 5120),
f(0) = a(b)⁰ = 5120
a = 5120
Now for the second point (1, 6400),
6400 = 5120(b)¹
b = [tex]\frac{6400}{5120}[/tex]
b = 1.25
Therefore, a = 5120 and b = 1.25 are the values.
Answer:
f(x)=8(0.5)^x

A daily newspaper sells monthly subscriptions for $15. Each individual copy of the newspaper costs $0.75. In a month that has exactly 30 days, how much could be saved by purchasing a subscription instead of purchasing an individual copy each day?
Answer:
With the subscription, $7.5 will be saved.
Step-by-step explanation:
Giving the following information:
A daily newspaper sells monthly subscriptions for $15. Each copy of the newspaper costs $0.75.
First, we need to calculate the total cost of buying 30 newspapers individually:
Total cost= 0.75*30
Total cost= $22.5
Difference= 22.5 - 15= $7.5
With the subscription, $7.5 will be saved.

Will mark as brainliest :)! Suppose that there were a strong correlation between the variables d and t.
Which of these is a true statement?
A. d must not cause f.
B. fmust cause d.
c. d may cause f.
D. d must cause f.
Answer:
c
Step-by-step explanation:
A strong correlations shows evidence of a relationship between the two quantities. It does not necessarily indicate that a change in one variable is causing a change in the other one. There MAY be a causal relationship, but the correlation, by itself, does not prove that.
An aquarium holds 11.95 cubic feet of water, and is 2.8 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.
Answer:
3.05feet
Step-by-step explanation:
Given data
Volume = 11.95 cubic feet
Lenght = 2.8 feet
Width= 1.4feet
Depth= ????
We know that the expression for the volume is
V= L*W*D
substitute
11.95= 2.8*1.4*D
11.95= 3.92D
divide both sides by 3.92
D= 11.95/3.92
D= 3.05
Hence the depth is 3.05feet approx
how do i find the radius of a cylinder when only given height and width
Step-by-step explanation:
The width of the cylinder might also be the diameter of its circular faces, and half of the diameter is the radius. So, dividing the width by 2 might give you the radius.
Two cars leave simultaneously from points A and B, the distance between which is 280 km. If the cars move to meet each other, they’ll meet in 2 hours. But if they move in the same direction, then the car going from point A will catch up with the car going from point B in 14 hours. What is the speed of each of the cars?
Answer:
Car A speed = 80 m/s
Car B speed = 60 m/s
Step-by-step explanation:
Let Speed of Car A be represented as x
Let Speed of Car B be represented as y
280 = (x+y)(2)140 = x+y --> Equation 1Let z represent the distance that Car A travels until it catches up to Car B
280+z = x(14)Since it takes 14 hours for Car B to cover the distance z,
z = 14y280+14y = 14x280 = 14(x-y)20 = x-y --> Equation 2Solving Equation 1 and Equation 2, we get:
x = y+20140 = 2y+20120 = 2yy = 60 x = y+20 = 80Answer:
Car A speed = 80 km/h
Car B speed = 60 km/h

The length of a rectangular screen is 6 feet, and the width of the screen is 8 feet. What is the length of a diagonal of this screen in feet?
Answer:
Length of diagonal = 10 feet
Step-by-step explanation:
Length of a rectangular screen = 6 feet
Width of the rectangular screen = 8 feet
Since, all interior angles of a rectangle are 90°,
Triangle formed with two adjacent sides and the diagonal will be a right triangle.
By applying Pythagoras theorem,
Hypotenuse² = (leg 1)² + (leg 2)²
(Diagonal)² = (leg 1)² + (leg 2)²
Diagonal = [tex]\sqrt{6^2+8^2}[/tex]
= [tex]\sqrt{100}[/tex]
= 10 feet
Sinx = [tex]\frac{3}{8}[/tex]
Find cosx and tanx
Answer:
Cos(x) = sqrt(55) / 8; tan(x) = 3/sqrt(55)
Step-by-step explanation:
Sine is opposite over hypotenuse. So we get that the opposite is 3 and the hypotenuse is 8. To find the adjacent (which we'll need for cosine and tangent), we can use pythagoras' theorem. Therefore, 8^2 = 3^2 + A^2, where A is the adjacent. A then must equal sqrt(64-9) = sqrt(55).
Cosine is adjacent over hypotenuse, which is then sqrt(55) / 8. Tangent is opposite over adjacent, which is then 3 / sqrt(55) or (sqrt55)*3/55

Using the formula below, calculate the z-score for the listed data points. z-score: zx = x − μ σ z1 = z5 = z6.5 =
Answer:
z1 = -1.95
z5 = 0.05
z6.5 = 0.8
Step-by-step explanation:
The value of the z score for a mean of 4 and standard deviation is 1.
What is Z score?The z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by:
z = (x - μ)/σ
Where x is the raw score, μ is the mean and σ is the standard deviation.
Let us assume that μ = 4, σ = 2, hence for x = 6:
z = (6 - 4) / 2 = 1
The value of the z score for a mean of 4 and standard deviation is 1.
