In a survey of 2 comma 3002,300 people who owned a certain type of car, 1 comma 2651,265 said they would buy that type of car again. What percent of the people surveyed were satisfied with the car?
Answer:
55% of the people surveyed were satisfied with the car
Step-by-step explanation:
The proportion of people surveyed who were satisfied with the car is the number of people who said they would buy that type of car again divided by the total number of people survied.
The percentage is the proportion multiplied by 100.
We have that:
2,300 people surveyed
1,265 said they would buy that type of car again.
1265/2300 = 0.55
0.55*100 = 55%
55% of the people surveyed were satisfied with the car

Answer:
i think the answer is "favorite zoo animal"
Step-by-step explanation:
because one thing that can't be an answer is "scariest zoo animal" because otter has the most vote and a lion or bear is scarier than a otter, so it can't be "scariest class pet* cause of the same reason. it can either be *favorite class pet" or "favorite zoo animal". if you see, in that on if we see the chart lion has the second highest votes and lion can't be a class pet, so it is "favorite zoo animal"

Son of Hannah‘s plants need water every day some need water every other day and some need water every third day if she what is an all today how many days will it be before she waters them all again
Answer:
3 days
Step-by-step explanation:
Some of Hannah‘s plants need water every 1 day.
Some need water every third(3) day.
If she waters them all today, we are to determine when next she will waters them all again.
To do this, we find the lowest common multiple of 1 and 3.
L.C.M of 1 and 3=3
Therefore, in 3 days time, she will water them all again.

The rail fare £16.25 is increased by 5%; how much does the fare now co st?
Given our current rail fare of £16.25, we are looking for the price of the rail fare after a 5% increase.
To find the value of a 5% increase, we can multiply the rail fare by 1.05 since it is 5% added to the total value.
Or, we can multiply the rail fare by 5 and then divide by 100 to get how much will be added onto it.
Let's do both of them:
Increase: 5%
Equation: 1.05 x 16.25
1.05 x 16.25 = 17.06 rounded to the nearest cent
Rail Fare after 5% increase: £17.06
Increase: 5%
Equation: (5 x 16.25)/100
81.25/100 = .81 rounded to nearest cent
Then, we add them together.
16.25 + 81 = 17.06
Rail Fare after 5% increase: £17.06

The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80. Option B is correct.
What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
The amount of revenue in dollars, y, that Jason receives from selling x posters is given by the equation y = 4x. The cost of producing x posters is given by the equation y = (1/2)x + 280.
Then the number of posters that Jason needs to sell so that the cost and revenue are equal will be given as,
4x = (1/2)x + 280
4x - (1/2)x = 280
(7/2)x = 280
7x = 560
x = 80
The number of posters that Jason needs to sell so that the cost and revenue are equal will be 80.

Step-by-step explanation:
To solve the problem, we need to write each fraction in decimal form.
Notice that each denominator is 10 based, which means we only have to move the decimal point according to the total number of zeros have the denominators. If the denominator is 10, we move the decimal point one spot to the left, if the denominator is 1000, we move the decimal point three spots to the left, and so on.

BD−→− bisects ∠ABC such that m∠ABD = (4x−5)∘ and m∠DBC = (3x+2)∘.
Find m∠ABC.
m∠ABC = ∘
Answer:
[tex]\angle ABC=(46)^{\circ}[/tex]
Step-by-step explanation:
Given: BD bisects [tex]\angle ABC[/tex]
[tex]\angle ABD=(4x-5)^{\circ}\\\angle DBC=(3x+2)^{\circ}[/tex]
To find: [tex]\angle ABC[/tex]
Solution:
A bisector of an angle divides it into angles of equal measures.
As BD bisects [tex]\angle ABC[/tex], [tex]\angle ABD=\angle DBC[/tex]
Put [tex]\angle ABD=(4x-5)^{\circ}\,,\,\angle DBC=(3x+2)^{\circ}[/tex]
[tex]\angle ABD=\angle DBC\\(4x-5)^{\circ}=(3x+2)^{\circ}\\4x-3x=2+5\\x=7^{\circ}[/tex]
So,
[tex]\angle ABD=(4x-5)^{\circ}=(4(7)-5)^{\circ}=(28-5)^{\circ}=(23)^{\circ}\\\angle DBC=(3x+2)^{\circ}=(3(7)+2)^{\circ}=(21+2)^{\circ}=(23)^{\circ}[/tex]
[tex]\angle ABC=\angle ABD+\angle DBC\\=(23)^{\circ}+(23)^{\circ}\\=(46)^{\circ}[/tex]
A bisector divides lines, angles and shapes into equal segments
The measure of angle ABC is 46 degrees
The given parameters are:
m∠ABD = (4x−5)∘ m∠DBC = (3x+2)∘Given that line BD is the bisector of angle ABC, it means that:
[tex]\angle ABD = \angle DBC[/tex]
and
[tex]\angle ABC = 2\times \angle ABD[/tex]
So, we have:
[tex]4x - 5 = 3x +2[/tex]
Collect like terms
[tex]4x - 3x = 5 +2[/tex]
Evaluate like terms
[tex]x = 7[/tex]
Recall that
[tex]\angle ABC = 2\times \angle ABD[/tex]
So, we have:
[tex]\angle ABC = 2 \times (4x - 5)[/tex]
Substitute 7 for x
[tex]\angle ABC = 2 \times (4\times 7 - 5)[/tex]
[tex]\angle ABC = 2 \times (28 - 5)[/tex]
[tex]\angle ABC = 2 \times 23[/tex]
[tex]\angle ABC = 46[/tex]
Hence, the measure of angle ABC is 46 degrees
