Answer:
Owen's songs were played on 3 movies and on 7 commercials.
Step-by-step explanation:
System of Equations
Let's call C the number of commercials on which Owen's songs were played and M the number of movies on which Owen's songs were played. We know Owen's songs were played on 4 more commercials than movies, it can be expressed as
[tex]C=M+4[/tex]
Owen will earn $50 every time one of his songs is played in a commercial and he will earn $140 every time one of his songs is played in a movie, so his total earnings are
[tex]140M+50C=770[/tex]
We have a system of linear equations that can be easily solved by using the formula for C in the above equation
[tex]140M+50(M+4)=770[/tex]
Operating
[tex]140M+50M+200=770[/tex]
Reducing
[tex]190M=770-200=570[/tex]
Solving
[tex]M=570/190=3[/tex]
The number of commercials is
[tex]C=M+4=7[/tex]
Owen's songs were played on 3 movies and on 7 commercials.

Find the total surface area of a square based prism (cuboid) of height 4cm, given that the side length of its base is 6cm.
please show working out
Total surface area of the square pyramid is 1476 cm².
Step-by-step explanation:
Step 1:Total surface area of a pyramid = 12pl + B. Here p is perimeter of the base which is a square = 4 × side, l is the slant height and B is the area of the base = side²
Step 2:Find perimeter of the base
⇒ p = 4 × side = 4 × 6 = 24 cm
Step 3:Find the slant height of the prism. l² = height² + (side/2)² (Based on Pythagoras Theorem)
⇒ l² = 4² + (6/2)² = 16 + 9 = 25
⇒ l = √25 = 5 cm
Step 4:Find the area of the base of the pyramid.
⇒ B = side² = 6² = 36 cm²
Step 5:Calculate total surface area of the pyramid.
⇒ TSA = 12 × 24 × 5 + 36 = 1440 + 36 = 1476 cm²

Jesse finished the first race in two minutes and seven seconds. Tim finished 12 seconds faster than Jesse. Juan finish eight seconds faster then Tim. How long did it take Juan to finish.
To find out how long it took Juan to finish, we add the time differences to Jesse's time. Tim finished 12 seconds faster than Jesse and Juan finished 8 seconds faster than Tim.
Explanation:To find out how long it took Juan to finish, we need to add the time differences to Jesse's time. First, we know that Tim finished 12 seconds faster than Jesse, so we can add 12 seconds to Jesse's time which becomes 2 minutes and 19 seconds. Next, we know that Juan finished 8 seconds faster than Tim, so we can add 8 seconds to Tim's time which becomes 2 minutes and 27 seconds. Therefore, it took Juan 2 minutes and 27 seconds to finish the race.

The cost c, in dollars, of a taxi ride is related to the
distance d, in miles, of the ride. The cost for taxi A is
given by the equation c = 3.5d + 2, and the cost for
taxi B is given by c= 3d + 5. For what distance is
the cost of each taxi ride the same? How much would
this trip cost?
Answer:
(3 , 2.5)
the trip would cost $12.5
12.5 = 3.5 (3)+2
12.5 = 3 (2.5)+5
Step-by-step explanation:
The distance at which the cost of each taxi is the same is 6 miles.
The trip would cost $23.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Example:
2x + 4 - 9 is an equation.
We have,
Taxi A:
c = 3.5d + 2
Taxi B:
c = 3d + 5
Where c is the cost of the taxi after d distance.
Now,
The cost of the taxi is the same.
3.5d + 2 = 3d + 5
3.5d - 3d = 5 - 2
0.5d = 3
d = 3/0.5
d = 30/5
d = 6
The cost of the taxi at d = 6.
c = 3.5d + 2 = 3.5 x 6 + 2 = 21 + 2 = 23
c = 3d + 5 = 3 x 6 + 5 = 18 + 5 = 23
Thus,
The cost of both taxis is the same after 5 miles.

4. The coordinates of the vertices of rectangle
ABCD are A(3,-2), B(3, 2), C(-3, 2), and
D(-3, -2).
a. Rectangle ABCD is rotated 90° about the
origin. What are the coordinates of the
vertices of rectangle A'B'C'D'?
b. What are the measures of the angles of
A'B'C'D'?
Answer: a) A'=(2, 3), B'=(-2,3), C'=(-2,-3) D'=(2,-3)
b) the measure of each angle is 90 degrees.
Step-by-step explanation:
a) To find the coordinates you need to know that (x,y) is changed to (-y,x). This means that they are flipped and changed from either negative to positive or positive to negative.
b) Each angle is 90 degrees because that shape is a rectangle with all equal right angles.
The coordinates of the vertices of rectangle A'B'C'D' after rotating rectangle ABCD 90° about the origin are A'(-2,-3), B'(-2,3), C'(-2,-3), and D'(2,-3). All angles in rectangle A'B'C'D' measure 90°.
Explanation:When a point is rotated 90° about the origin, the new coordinates can be found using the formula (y, -x). Therefore, applying this to each vertex of the rectangle, A'(3,-2) becomes A'(-2,-3), B'(3, 2) becomes B'(-2,3), C'(-3, 2) becomes C'(-2,-3) and D'(-3, -2) becomes D'(2,-3).
Since A'B'C'D' is a rectangle, all its angles are right angles. This means all the angles measure 90°.

K = 4D. K = D + 6
4D = D + 6
-D. -D
3D = 6
3. 3
D = 2
Answer:
d=2
Step-by-step explanation:
We can use the given information to write down two equations that describe the ages of Kevin and Daniel.
Let Kevin's current age be k and Daniel's current age be d.
k=4d
k=d+6
Now we have two independent equations, and we can solve for our two unknowns.
Since we are looking for d, and both of our equations have k alone on one side, this is a convenient time to use elimination.
Subtracting the second equation from the first equation, we get:
0=4d-(d+6)
which combines the information about d from both of our original equations.
Solving for d, we get: 3d = 6.
d=2
Vocabulary How can you tell if
a
fraction is a unit fraction?
A unit fraction is a fraction with a numerator of 1 and a positive integer denominator. Identifying unit fractions involves ensuring the numerator is 1. Examples include 1/2, 1/3, and 1/5.
A unit fraction is a fraction where the numerator is always 1, and the denominator is a positive integer. This means that a fraction of the form 1/b, where b is a positive integer, qualifies as a unit fraction. For example, 1/2, 1/3, and 1/5 are unit fractions because the numerators are all 1.
When working with fractions, it's important to understand their components. The numerator (top number) represents how many parts you have, while the denominator (bottom number) tells you into how many equal parts the whole is divided. This rule helps identify unit fractions, as the numerator must always be 1.
To summarize, determining unit fractions is straightforward: check if the numerator is 1 and the denominator is a positive integer. If both conditions are met, you have a unit fraction.

Triangle ABC has verrocktes A (2,-1) B ( -3,0) and C ( -1,4) . Find the vertices of the image of triangle and after a translation of 2 units up
Answer:
A(2,1) , B(-3,2) , C(-1,6)
Step-by-step explanation:
A translation of 2 units up means the y values will be shifted up 2 units
A (2,-1) -> A(2,1)
B (-3,0) -> B(-3,2)
C (-1,4) -> C(-1,6)
The vertices of the image of triangle ABC after a translation of 2 units up are A' (2, 1), B' (-3, 2), and C' (-1, 6), found by adding 2 to the y-coordinate of each original vertex.
The student has asked how to find the vertices of the image of triangle ABC after a translation of 2 units up. To do this, we simply add 2 to the y-coordinate of each vertex of the triangle. Here are the steps for the translation:
For vertex A (2, -1), the new position after translation is A' (2, -1 + 2) or A' (2, 1).
For vertex B (-3, 0), the new position after translation is B' (-3, 0 + 2) or B' (-3, 2).
For vertex C (-1, 4), the new position after translation is C' (-1, 4 + 2) or C' (-1, 6).
Therefore, the vertices of the image of triangle ABC after the translation are A' (2, 1), B' (-3, 2), and C' (-1, 6).

A grocer has two kinds of candies, one selling for 40 cents a pound and the other for $1.40 per pound. How many pounds of each kind must he use to make 100 pounds worth 85 cents a pound?
Answer: 55 lbs of $0.40 and 45 lbs of $1.40
Step-by-step explanation:
Let's say that we have two buckets, one that weighs x pounds and the candies in it are $0.40 per pound and another that weighs 100-x pounds (because we know the two added together must be 100 pounds) and the candies in it are $1.40 per pound.
There is a third bucket that is made when you combine the two, it weighs 100 pounds and the candies in it are $0.85. Multiply the cents per pound by the pounds of the candy for each bucket and you get this equation:
0.4 * x + 1.4 (100-x) = 0.85 * 100
Solve!
0.4x + 140 - 1.4x = 85
-x + 140 = 85
-x = -55
x = 55
From this we get that 100 - x = 45.
So, the answer is 55 lbs of $0.40 and 45 lbs of $1.40
ANSWER: 55 lbs of $0.40 and 45 lbs of $1.40
Step-by-step explanation:
Let's say that we have two buckets, one that weighs x pounds and the candies in it are $0.40 per pound and another that weighs 100-x pounds (because we know the two added together must be 100 pounds) and the candies in it are $1.40 per pound.
There is a third bucket that is made when you combine the two, it weighs 100 pounds and the candies in it are $0.85. Multiply the cents per pound by the pounds of the candy for each bucket and you get this equation:
0.4 * x + 1.4 (100-x) = 0.85 * 100
Solve!
0.4x + 140 - 1.4x = 85
-x + 140 = 85 .
-x = -55
x = 55
From this we get that 100 - x = 45.
So, the answer is 55 lbs of $0.40 and 45 lbs of $1.40

If $1800 is invested at 2% interest compounded annually find the total amount in 3 years.
Answer:
$1910.1744
Step-by-step explanation:
To start we have to calculate how much the total will give us in one year, for this we divide the number by 100 and multiply it by 102, so we will get that 2% in one year
(1800 / 100) * (100 + 2) =
18 * 102
1836
Now we will repeat the procedure but instead of using the 1800 we will use the 1836 which will be what we will have when the first year ends.
(1836 / 100) * (100 + 2) =
18.36 * 102
1872.72
Finally we do the same with the new number
(1872.72 / 100) * (100 + 2) =
18.7272 * 102
1910.1744
So in conclusion putting $1800 at the end of the 3 years we will get $1910.1744
$1910.1744 - $1800 = $110.1744
that is the exact amount of the profit that we will obtain.

A weather forecast states that there is a 20% probability of rain in the next three days. Describe a simulation you could perform using random numbers to find the experimental probability that it will not rain on any of the next 3 days.
To simulate the 20% probability of rain over three days, generate a random number between 1 and 100 for each day. Count the trials where all three numbers are between 21 to 100 as 'non-rainy' days. The experimental probability of no rain in three days is the ratio of 'non-rainy' trials to total trials.
Explanation:Probability is a branch of mathematics that studies randomness and the chance of an event occurring. In this case, we can perform a simulation to experimentally determine the probability that it will not rain on the next 3 days even though there is a forecast of a 20% chance of rain.
One way to perform the said simulation is by using random numbers from 1 to 100. Why? Because probability can be expressed as a percentage, and the range from 1 to 100 encompasses all percentage possibilities (0% to 100%). So, for each day, we can generate a random number in this range. If the generated number falls in the range 1-20 (which represents the 20% predicted chance of rain), we consider that day as a 'rainy day'. If it falls in the range 21-100, we consider it a 'non-rainy day'.
We repeat this process for three days. The experimental probability of it not raining on all three days will be the ratio of favorable outcomes (all three numbers landing in the 'non-rainy day' range) to the total number of trials.
If we perform a large number of these three-day simulations, we'll have a good estimate of the experimental probability. The Law of Large Numbers ensures that as more trials are conducted, the experimental probability will approach the theoretical probability.
