Layla takes 32 minutes to ride 8-mile long trail.
Given Last week, Layla took 24 minutes to ride a trail that is 6 miles long.
So Speed of Layla to cover 6 miles is , [tex]\frac{6}{24} =0.25[/tex] miles per minute.
Now, Layla kept same speed of 0.25 miles per minute to rode 8-mile trail.
So, Time taken by Layla to cover 8 miles is [tex]\frac{distance}{speed}[/tex][tex]=\frac{8}{0.25} = 32[/tex] minutes.
Hence Layla takes 32 minutes to ride 8-mile long trail.

Step-by-step explanation:
This problem is completing our example from the end of the recording today.) We have a 20 foot ladder and lean it against the house at a 75 degree angle with the ground. a) How far up the house does the ladder reach? b) How far from the house is the bottom of the ladder?
Answer:
a) The ladder reach 19.32 foot up the house
b) The bottom of the ladder is 5.18 foot from the house
Step-by-step explanation:
An illustrative diagram of the scenario is attached below.
From the diagram, we have a right angle triangle with the length of the ladder being the hypotenuse. The opposite indicates how far up the house the ladder reach and the adjacent indicates the distance of the bottom of ladder from the house.
a) To determine how far up the house the ladder reach, that is the opposite. Let the opposite be y
From the formula
Sinθ = Opposite / Hypotenuse
Where θ is the angle subtended
Here θ = 75°
Hypotenuse = 20 foot
∴ sin75° = y / 20
y = 20 × sin75°
y = 20 × 0.9659
y = 19.32 foot
Hence, the ladder reach 19.32 foot up the house.
b) To determine how far from the house the bottom of the ladder is, that is the adjacent. Let the adjacent be x
From the formula
Cosθ = Adjacent / Hypotenuse
Where θ is the angle subtended
Then,
cos75° = x / 20
∴ x = 20 × cos75°
x = 20 × 0.2588
x = 5.18 foot
Hence, the bottom of the ladder is 5.18 foot from the house.

One of these cards is selected at random. Let A denote the event that is chosen. Find the probability that is chosen, and express your answer in probability notation.
Complete question is;
An ordinary deck of playing cards has 52 cards. There are four suits
-spades, hearts, diamonds, and clubs
-with 13 cards in each suit.
Spades and clubs are black; hearts and diamonds are red. One of these cards is selected at random. Let A denote the event that a red card is chosen.
Find the probability that a red card is chosen, and express your answer in probability notation.
Answer:
P(A) = 0.5
Step-by-step explanation:
We are told that the ordinary deck of playing cards has 52 cards.
Now, there are four suits
-spades, hearts, diamonds, and clubs
-with 13 cards in each suit.
Now, in a standard set of playing cards, there are 13 black spades and 13 black clubs as well as 13 red hearts and 13 red diamonds
Thus;
Number of red cards = 13 + 13
Thus;
Number of red cards = 26
Since, A denotes the event that red card is chosen.
This means that probability of choosing a red card is;
P(A) = number of red cards/total number in a deck of cards
P(A) = 26/52
P(A) = 0.5
When Carla looked out at the school parking lot, she noticed that for every 2 minivans, there were 5 other types of vehicles. If there are 161 total vehicles in the parking lot, how many of them are minivans?
Answer:
46 of the total vehicles are minivans
Step-by-step explanation:
Let the number of minivans be x
and the number of other types of vehicles be y
From the question,
Carla noticed that for every 2 minivans, there were 5 other types of vehicles.
This means the ratio of minivans to other types of vehicles is 2:5.
Therefore,
x:y = 2:5
We can then write that
x/y = 2/5
∴ 5x = 2y ...... (1)
Also from the question,
There are 161 total vehicles in the parking lot
That is
x + y = 161 ...... (2)
From equation (2), we can write that
y = 161 - x
Put this into equation (1)
5x = 2y
Then
5x = 2(161-x)
5x = 322 -2x
5x+2x = 322
7x = 322
x = 322/7
x = 46
Since x represent the number of minivans
Hence, 46 of the total vehicles are minivans.

Which ratio is equivalent to the ratio 33:39?
The ratio which is equivalent to 33:39 is 11:13
Equivalent ratioAn equaivalent ratio are fraction whose value are equal and are integral multiples of each other.
For example 1:2 = 2:4
Since 1:2 = 1 × 2 : 2 × 2 = 2 : 4
Also, 2:4 = 2 ÷ 2: 4 ÷ 2 = 1 : 2
We see that 1:2 and 2:4 are equivalent since we multiply 1:2 by 2 to get 2:4 or divide 2:4 by 2 to get 1:2.
Finding the equivalent ratio to 33:39So, to find the ratio equivalent to 33:39, we write 33:39 in its simplest terms.
So, 33:39 = 11 × 3 : 13 × 3
= 11 : 13
So, the ratio which is equivalent to 33:39 is 11:13

A box of cereal states that there are 72 calories in a 3 4-cup serving. What is the unit rate for calories per cup? How many calories are there in 4 cups of the cereal?
Answer:
96 calories per cup
384 calories in 4 cups
Step-by-step explanation:
In this scenario, we can use the rule of three to calculate the number of calories in a single cup like so...
72 calories <==========> [tex]\frac{3}{4} cup[/tex] or 0.75 cup
x calories <==========> 1 cup
(1 * 72) / 0.75 = 96 calories
Now we see that there are a total of 96 calories per cup of cereal. In order to find the total amount of calories in 4 cups of cereal, we simply need to multiply the number of calories per cup by 4, like so...
96 * 4 = 384 calories
There are a total of 384 calories in 4 cups of cereal.

At noon, a tank contained 10 cm water. After several hours, it contained 3 cm of water. What is the percent decrease of water in the tank? The percent decrease in water in the tank is nothing%.
Answer:
70%
Step-by-step explanation:
Given that:
Initial water level in the tank at noon = 10 cm
After several hours, water level = 3 cm
To find the percentage change in the water in the tank, we can use the following formula:
[tex]Percentage\ Change = \dfrac{Final\ Value - Initial\ Value }{Initial\ Value}\times 100[/tex]
Here, Final Value = 3 cm
Initial Value = 10 cm
Putting the values in the formula:
[tex]Percentage\ Change = \dfrac{3 - 10 }{10}\times 100\\\Rightarrow Percentage\ Change = -70\%[/tex]
Here, negative value, means there is a decrease in the final value from the initial value.
Therefore, the answer is 70% decrease.

stan earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday evening. He earned $160 in all. To the nearest hour, what is the least number of hours Stan would have to work to earn this much money?
Answer:
8 hours
Step-by-step explanation:
Calculator 60 divided by 7.55= 7.94 round to 8
The amount of time Stan works to earn $160 will be 7.94 hours.
What is an expression?Expression in maths is defined as the collection of the numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that Stan earned $7.55 per hour plus an additional $100 in tips waiting tables on Saturday evenings. He earned $160 in all.
The working time will be calculated by making an equation assuming the working time to be x hours.
7.55x + 100 = 160
7.55x = 160 - 100
7.55x = 60
x = 60 / 7.55 = 7.94 hours.
Therefore, the amount of time Stan works to earn $160 will be 7.94 hours.
