Answer: The dolphin's average speed is 3 mph
Step-by-step explanation: The basic equation is Speed = Distance ÷ Time
S = d/t
To find miles per hour, divide the distance in miles by the time in hours.
Speed = 12 miles/4 hours . 12÷4 = 3
Speed = 3 mph

Ross has a season ticket.
In 2013 the season ticket cost £65.
In 2014 the cost of the ticket was increased by 8%.
In 2015 the cost of the ticket was increased by a further 5%.
Calculate the cost of the season ticket after the two price increases.
Answer:
£73.71
Step-by-step explanation:
Let's compute first for the cost of the ticket in 2014. Let x be the increase in the cost of the ticket. If the cost of the ticket is 8% of £65, then the expression should be like this:
x = 65 x 8%x = 65 x 0.08x = £5.2Let's add £5.2 to £65 ⇒ £5.2 + £65 = £70.2
The cost of the season ticket in 2014 is £70.2.
Next, we'll have to compute the cost of the ticket in 2015. Let y be the increase in cost of the ticket. If the cost of the ticket is 5% of £70.2, then the expression should be like this:
y = 70.2 x 5%y = 70.2 x 0.05y = £3.51Let's add £3.51 to £70.2 ⇒ £3.51 + £70.2 = £73.71
The cost of the season ticket in 2015 is £73.71. This is also the cost of the season ticket after two price increases.

Which of the polygons has the greatest area?
Group of answer choices
A square with side length of 4.6 inches.
A triangle with a base of 7.18 inches and a height of 5.4 inches.
A parallelogram with a base of 5.875 inches and a height of 3.5 inches.
A rectangle that is 3.25 inches wide and 6.1 inches long.
Answer:
A triangle with a base of 7.18 inches and a height of 5.4 inches
Step-by-step explanation:
You have to multiply 7.18 by 5.4
7.18*5.4=38.772
If you do the math to the other equations, they are all less then the triangle.
5) In August, Yesenia was 4 feet tall. Each month since August, she has consistently grown 0.25 inc
How tall is Yesenia t months after August?
Answer:
Yesenia is 0.25t+4 inches tall after August.
Step-by-step explanation:
Given that:
Height of Yesenia in August = 4 feet tall
Growth rate since August = 0.25 inches
Number of months after August = t
According to given statement;
Height after August = Growth rate * Number of months + Height in August
Height after August = 0.25t + 4
Hence,
Yesenia is 0.25t+4 inches tall after August.

Which statement about stratified random sampling is true? A stratified random sample is a combination of simple random samples selected from each of several strata. A stratified random sample is formed by selecting one stratum from a simple random sample of the population. A selection of every 3rd person from an alphabetical list of a population forms a stratified random sample. A stratified random sample consists of choosing several strata, and each stratum is representative of the entire population.
Answer:
A. A stratified random sample is a combination of simple random samples selected from each of several strata.
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
There are various types of sampling used by researchers and these are;
1. Random sampling.
2. Convenience sampling.
3. Systematic sampling.
4. Cluster sampling.
5. Stratified sampling.
Stratified random sampling can be defined as a method of sampling that involves dividing a population into smaller groups known as strata.
In stratified random sampling, the strata are formed based on member's shared characteristics (e.g female or male, occupation, education) or attribute (e.g black or white).
Hence, the statement about stratified random sampling which is true is that, a stratified random sample is a combination of simple random samples selected from each of several strata.

Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot
Answer:
15 feet
Step-by-step explanation:
Michele wanted to measure the height of her school's flagpole to place on the ground 35 ft from the flagpole then walks backwards until she was able to see the top of the pole in the mirror her eyes were 5 feet above the ground and she was 12 ft away from the mirror using similar triangles, find the height of the flagpole to the nearest of a foot
Using similar triangles
= Let the height of the flagpole be represented as h.
h/35 =5/12
We cross Multiply
35 x 5 = 12h
12h = 175
h = 175/12
h = 14.583333333 feet
Approximately to the nearest foot is
h = 15 feet

On a certain day the temperature in Austin was 10.2°C and the temperature in New York City was -4.8°C. What is the difference in temperature between the two cities?
Show your work please and if you do you get 60 points!!!!
good luck and please don't get the wrong answer. it took me a long time to get the points so please and good luck!
Answer:
15°C
Step-by-step explanation:
Find the difference by subtracting -4.8 from 10.2
10.2 - (-4.8)
Subtracting a negative number changes to adding a positive number:
10.2 + 4.8
= 15
So, the difference in temperature between the two cities is 15°C

-10\left(-\frac{1}{2}+\left(-\frac{7}{2}\right)+7y=25
Answer:
[tex]y=\frac{47}{14}[/tex]
Step-by-step explanation:
Given
[tex]-10\left(-\frac{1}{2}\right)+\left(-\frac{7}{2}\right)+7y=25[/tex]
Required
Solve for y
[tex]-10\left(-\frac{1}{2}\right)+\left(-\frac{7}{2}\right)+7y=25[/tex]
Open brackets
[tex]\frac{10}{2}-\frac{7}{2}+7y=25[/tex]
Collect Like Terms
[tex]7y=25 -\frac{10}{2}+\frac{7}{2}[/tex]
Take L.C.M
[tex]7y=\frac{50-10+7}{2}[/tex]
[tex]7y=\frac{47}{2}[/tex]
Divide both sides by 7
[tex]y=\frac{47}{2*7}[/tex]
[tex]y=\frac{47}{14}[/tex]
Evaluate the expression for the given value of the variable.
46 + 1/5r
r = -1/2
Answer:
[tex]45\frac{9}{10}[/tex] or [tex]45.9[/tex]
Step-by-step explanation:
All we have to do here is substitute the given value of [tex]r[/tex] into the given expression. Therefore, after substituting [tex]r=-\frac{1}{2}[/tex] into [tex]46+\frac{1}{5}r[/tex], we get:
[tex]46+\frac{1}{5}r[/tex]
[tex]= 46+\frac{1}{5}*(-\frac{1}{2} )[/tex] (Substitute [tex]r=-\frac{1}{2}[/tex] into [tex]46+\frac{1}{5}r[/tex])
[tex]=46-\frac{1}{10}[/tex] (Multiply)
[tex]=45\frac{9}{10}[/tex] or [tex]45.9[/tex] (Simplify)
Hope this helps!
Hey there!
The answer to your question is [tex]45\frac{9}{10}[/tex]
We can find this by simply plugging in the "r" value into the given equation.
46 + [tex]\frac{1}{5}[/tex] ([tex]\frac{-1}{2}[/tex])
Now we evaluate the equation:
46 + [tex]\frac{1}{5}[/tex] ([tex]\frac{-1}{2}[/tex])
46 + [tex]\frac{-1}{10}[/tex]
[tex]45\frac{9}{10}[/tex]
Hope this helps and have an amazing day!

Alicia drew a map of Texas. In the scale Alicia used for the map, .50 inch represents 20 miles. What is the distance between two cities on the map if the actual distance between the two cities is 360 miles?
Answer:
An actual distance of 360 miles correspond to 9 inches on the map
Step-by-step explanation:
From the question, we have a scale of 0.5 inches representing 20 miles
Now, we want to relate an actual distance of 360 miles to a measurement on the map using the scale
From here, we have that;
0.5 inches = 20 miles
x inches = 360 miles
x * 20 = 0.5 * 360
20x = 180
x = 180/20
x = 9 inches
