Answer:
here is the ratio 1 : 1.25 (sharks: dolphins)
Step-by-step explanation:
The ratio of sharks to dolphins is 4 : 5
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
Given Number of sharks = 4
Number of dolphins = 5
Therefore, the ratio of sharks to dolphins
= 4 : 5
Or 1 : 1.25
Number of animals = number of sharks + number of dolphins
Number of animals = 4 + 5 = 9

In last Quiz, Ahmed answered 24 out of 30 questions correctly. In this quiz he answered 20 out of 24 questions correctly. On which quiz did Ahmed have better results?
Answer:
He scored better on the second test by a margin of 3%.
Step-by-step explanation:
Find the percentage of each one by dividing Ahmed's score / Total possible score
24/30 = 0.8 > move the decimal place over twice for % > 80%
20/24 = 0.83333 > move the decimal place over twice for % > 83%
He scored 3% better on the second test.

Stefan sells Jin a bicycle for $116 and a helmet for $16. The total cost for Jin is 110% of what Stefan spent originally to buy the bike and helmet. How much did Stefan spend originally? How much money did he make by selling the bicycle and helmet to Jin?
Answer:
He originally spent 120$
He made 12 extra dollars.
Step-by-step explanation:
To solve this I turned the 110% into a decimal.
So I divided 110 by 100 and got 1.1
In order to find the original number you would then need to divide the total cost of the bicycle and helmet together by 1.1
So, 116 + 16 = 132
132/1.1= 120
Hope this helps
In a survey of 2300 people who owned a certain type of car, 460 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
20%
Step-by-step explanation
let's assume 100% = 2300
x% = 460
100% / x% = 2300/460
460x100/2300 = 20
the answer is 20%
Answer:
The survey shows that 20% of the individuals were satisfied with the car.
Step-by-step explanation:
We are given that 2,300 people were surveyed.We are also given that 460 of those individuals would buy that car again.We need to find the percentage of individuals that were satisfied with the car.When we need to find the percentage of a population, we can use the following formula:
[tex]\displaystyle \frac{\text{part}}{\text{whole}} \times 100[/tex]We need to identify the part and the whole in this problem.
We are given that 2,300 people are surveyed, so this is the whole portion.
We are also given that 460 were satisfied, so this is the part portion.
Therefore, we can set up our fraction.
[tex]\displaystyle \frac{460}{2300}[/tex]Now, let's solve the percentage.
[tex]\displaystyle \frac{460}{2300} \times 100\\\\\frac{2}{100} \times 100 = 20\%[/tex]
Therefore, of those surveyed, 20% of the individuals were satisfied with the car.

help? I know what i’m doing somewhat but i really just didn’t wanna pay attention in class the day this was taught
To solve the equation for x, first divide both sides of the equation by 4 to get [tex]e^{2.7x}=\frac{33}{4}[/tex]. Then, take the natural logarithm of both sides (base e) to get [tex]\ln e^{2.7x} = \ln (33/4)[/tex]. The left hand side of this equation if equal to 2.7x, so we get [tex]2.7x = \ln(33/4)[/tex]. The final step is to divide both sides of the equation by 2.7, to get that [tex]x =\frac{ \ln (33/4)}{2.7}[/tex]. This is approximately equal to 0.782.

Answer:
It would be -13
Step-by-step explanation:
Answer:
-13
Step-by-step explanation:
You need to separate the 8 from each side of the equation. Picture it like this:
-104= 8 (multiplied by) x
To separate 8 from the variable, you need to divide that side by 8. Similarly, you need to do the same thing to the other side.
-104/8=8x/8
-13=x
Find the product of 11/12 (-2.4)
Answer:
-1.961666666666
Step-by-step explanation:
The highest level of PEMDAS here is multiplication/division which is done left to right. So do 11/12 first.
11/12 (-2.4)
.916 (-2.4)
Then multiply to get an answer of -1.961666666 ( the six repeats forever)
Jennifer wants to buy a new television set that regularly sells for $900. Because she works at the store, Jennifer will receive an employee discount of 30% off the regular price, but she will have to pay 6% sales tax on the adjusted price. What will be Jennifer's final cost to buy the television?
Answer:
$667.80
Step-by-step explanation:
30% of 900 is 270, so the price of the TV would be 630 without the tax. 6% of 630 is 37.8, so in total, the price would be $667.80
A roof rises 15 feet vertically and 12 feet horizontally. What is the slope of the roof?
Answer: 15/12 or in simplest form its 5/4
Step-by-step explanation:
Slope is rise/run
Answer:
Do you know rise over run?? The roof goes up 15 feet and to the left or right 12 feet... the slope would be 15/12 or it would be 1.25 (when divided). Hope it helps!

[tex] \frac{ {7x}^{2} - 5x + 1}{4x + 1} [/tex]
Step-by-step explanation:
Since the denominators are the same we just have to combine the top.
[tex] {x}^{2} - 5x + {6x}^{2} + 1[/tex]
Combine alike terms.
[tex] {7x}^{2} - 5x + 1[/tex]

Casey wants to buy a gym membership. One gym has a $176 joining fee and costs $29 per month. Another gym has no joining fee and costs $51 per month.
Part 1 out of 2
In how many months will both gym memberships cost the same? What will that cost be?
Answer:
8 months for cost to be same, cost will be $408
Step-by-step explanation:
x = months
176 + 29x = 0 + 51x
176 = 22x
8 = x
176 + (29*8) = 408
0 + (51*8) = 408
