Answer:
45%
Step-by-step explanation:
1. We assume, that the number 2300 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 2300, so we can write it down as 100%=2300.
4. We know, that x% equals 1035 of the output value, so we can write it down as x%=1035.
5. Now we have two simple equations:
1) 100%=2300
2) x%=1035
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=2300/1035
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for 1035 is what percent of 2300
100%/x%=2300/1035
(100/x)*x=(2300/1035)*x - we multiply both sides of the equation by x
100=2.2222222222222*x - we divide both sides of the equation by (2.2222222222222) to get x
100/2.2222222222222=x
45=x
x=45
1035 people said they would purchase the car again, so they are the people that were satisfied with it. Now, divide this number of people by the number of people who owned that type of car to find your percentage. Here is how you would do that:
1035 ÷ 2300= 0.45
0.45 × 100= 45%
Therefore, 45% of the people surveyed were satisfied.

find the area of the small sector
8 and 40
area=m2
(round to the neerest 100)
Answer:
22.33 m²
Step-by-step explanation:
From the question given above, the following data were obtained:
Radius (r) = 8 m
Angle sustained (θ) = 40°
Pi (π) = 3.14
Area of small sector (A) =?
The area of the small sector can be obtained as illustrated below:
A = θ/360 × πr²
A = 40/360 × 3.14 × 8²
A = 40/360 × 3.14 × 64
A = 22.33 m²
Therefore, the area of the small sector is 22.33 m²
A bag contains eight red marbles and 12 green marbles you choose a marble out of the bag without looking what is the probability that you choose a red marble
Answer:
2/5
Step-by-step explanation:
Probability of choosing red = total red marbles / sum of marbles in the bag
sum of marbles in the bag = 12 + 8 = 20
8/20 = 2/5
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.

B) Prove or disprove by example or by exhaustive checking that every integer greater than 1 is either prime or sum of two primes.
Answer:
Every integer greater than 1 is either prime or composite.
Step-by-step explanation:
Let us negate this statement.
Assumption - any number greater than 1, is neither prime nor composite.
A prime number has only 2 divisors, and a composite number has at least 3.
Let a number be X such that X >1.
Now X is divisible by 1 (Any integer is divisible by 1)
And X is divisible by X (X/X = 1, if X is not zero)
So by this, we see X has at least 2 divisors, X is either prime, or composite if it has more divisors!
So our assumption is wrong, and every integer greater than 1 is either prime or composite.

Ten students participated in the 4 mile relay. Each student ran a fraction of the 4 miles. Chooses which line plot could represent the data of the runners. Explain your reasoning.
Answer:
B
Step-by-step explanation:
To know which line plot could represent the data, we take the sum of the miles covered by the runners and check if it adds up to 4 miles for each plot :
Plot 1 :
(1/12 * 1) + (1/8 * 2) + (1/6 * 1) + (1/4 * 2) + (1/3 * 1) + (1/2 * 3) = 2.8333
Plot 2 :
(1/6 * 2) + (1/4 * 2) + (1/3 * 2) + (1/2 * 3) + 1 = 3 +1 = 4 miles
Since the sum of the miles ran by the runners equals 4 miles for the second plot, hence, the second plot could represent the data for the runners.

What is the congruence correspondence, if any, that will prove the given triangles congruent?
A. SSS
B. ASA
C. HL
D. SAS
Answer:
SAS
Step-by-step explanation:
the two triangles have two congruent sides and one congruent angle
The two given triangles are congruent by the side angle side (SAS) property. The correct option is D.
What is congruency?The Side-Angle-Side Congruence Theorem (SAS) defines two triangles to be congruent to each other if the included angle and two sides of one is congruent to the included angle and corresponding two sides of the other triangle.
An included angle is found between two sides that are under consideration.
In the given figure demonstrates two triangles that are congruent by the SAS Congruence Theorem.
Two triangles having two pairs of corresponding sides and one pair of corresponding angles that are congruent to each other is not enough justification for proving that the two triangles are congruent based on the SAS Congruence Theorem.
Therefore, the two given triangles are congruent by the side angle side (SAS) property. The correct option is D.

one third of the one third of a number is 12 find the number
Answer:
4
Step-by-step explanation:
Let the number be x
1/3 Of x= 12
1/3x=12
cross multiply
12= 3x
divide both sides by 3
x= 12/3
x= 4
Hence the number is 4

On selling 250 cascades, a man had an equal gain to the selling price of 25 cascades. Find his gain percent
Answer:
11.11%
Step-by-step explanation:
The selling price is 250
The cost price is 250-25
= 225
Therefore the gain can be calculated as follows
=250-225x/225x×100
1/9 ×100
= 0.1111×100
= 11.11%
Hence the gain is 11.11%

Stuart owns a window washing business. He can wash the windows on 9 houses in 4 hours. At this rate, how long would it take him to wash the windows on 45 houses? How many houses could he wash in 12 hours?
Answer:
20 Hours = 45 Houses
27 = 12 Hours
Step-by-step explanation:
The time taken to wash 45 houses is 20 hours and the number of houses in 12 hours is 27.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Stuart owns a window-washing business. He can wash the windows on 9 houses in 4 hours.
The time taken to wash 45 houses is,
9 houses = 4 hours
1 house = 4 / 9 hours
45 houses = ( 45 x 4 ) / 9 hours
45 houses = 20 hours
The number of houses in 12 hours,
4 hours = 9 houses
1 hour = 9 / 4 houses
12 hours = ( 9 x 12 ) / 4 houses
12 hours = 27 houses
Therefore, the time taken to wash 45 houses is 20 hours and the number of houses in 12 hours is 27.

The mean weight of nine apples is 7.5 ounces. Three of the apples have
a mean weight of 8 ounces. Find the mean weight of the other
six apples.
9514 1404 393
Answer:
7.25 ounces
Step-by-step explanation:
The sum of weights is the mean weight times the number of apples.
sum of 9 = 7.5×9 = 67.5 . . . ounces
sum of 3 = 8×3 = 24 . . . ounces
Then the sum of the weights of the remaining 6 is ...
67.5 -24 = 43.5 . . . ounces
The mean weight of those 6 is ...
(total weight of 6)/6 = mean weight of 6
(43.5 oz)/(6) = 7.25 oz
The mean weight of the other 6 is 7.25 oz.
_____
Additional comment
If some have an average weight that is greater than the mean of all, the remaining must have an average weight that is less than the mean of all.

Answer:
HI=1/2*EF
17-3x=1/2*-9x+37
2(17-3x)=-9x+37
34-6x=-9x+37
-6x+9x=37-34
3x=3
x=3/3
x=1
now substitute the value of HI
17-3x
=17-3*1
=17-3
=14
Step-by-step explanation:
Note :HI=1/2*EF because the straight line joining the mid points of two sides of a triangle is parallel to the third side and equal to half of it.
The area of a sector is 9pi cm^2 . The sector cover 1/4 of the entire circle. Find the radius of the circle. Thank you.
Given:
The area of a sector = [tex]9\pi\text{cm}^2[/tex]
The sector cover [tex]\dfrac{1}{4}[/tex] of the entire circle.
To find:
The radius of the circle.
Solution:
Let r be the radius of the circle. Then, the area of the circle is:
[tex]A=\pi r^2[/tex]
It is given that the sector cover [tex]\dfrac{1}{4}[/tex] of the entire circle. So, the area of the sector is equal to [tex]\dfrac{1}{4}[/tex] of the area of the entire circle.
[tex]9\pi=\dfrac{1}{4}\times \pi r^2[/tex]
Multiply both sides by 4.
[tex]36\pi =\pi r^2[/tex]
Divide both sides by [tex]\pi[/tex].
[tex]36 =r^2[/tex]
Taking square root on both sides.
[tex]\pm \sqrt{36} =r[/tex]
[tex]\pm 6 =r[/tex]
Radius of a circle cannot be negative. So, [tex]r=6[/tex].
Therefore, the radius of the circle is 6 cm.
