lettered A to E. Lena
spins the pointer on
the spinner 25 times.
She records her
results in the table.
Based on these results,
lands on the letter B?
B is 5
Answer:
1/5
Step-by-step explanation:
there are 5 sections regardless of how many time she rolls it ti does not change the probability of landing on b so it's 1/5

please help find the central angle and perimeter !
Step-by-step explanation:
We will have the following
*First: We have that the area of a sector of a circle is given by the expression:
A = r²a/2
Here r is the radius and alpha is the central angle.
*Second: We determine the central angle as follows:
[tex]36\pi =[/tex]
(12)²a/2 ➡️ a = 36í•2/(12) ²➡️
[tex]a = \frac{1}{2} \pi[/tex]
So, the central angle has a measurement of 1/2 pi.
Third: We determine the perimeter of the sector as follows:
First: we determine the arc length with two times the radius, that is:
p = 2(12) +
[tex]6\pi[/tex]
➡️ p = 24 +
[tex]6\pi[/tex]
So, the perimeter of the sector is 24+ 6pi meters [ Approximately 43 meters].

Paulo has a receipt from a restaurant. The total amount is blurred, but he knows he left a $4.25 tip, which was 20% of the cost of the meal. How much did his meal cost? How much did he spend in total?
Answer:
$21.25
Step-by-step explanation:
20% of the meal (x) = 4.25
20/100= 0.2
0.2 * x= 4.25
0.2x= 4.25
(divide both sides by 0.2)
x= $21.25

two squares. If so, factor it. If not, explain why.
Answer: It is a difference of two squares, and it factors to (3x-7)(3x+7)
=============================================================
Explanation:
We can write the 9x^2 as (3x)^2 since
(3x)^2 = (3x)*(3x) = (3*3)*(x*x) = 9x^2
The 49 can be written as 7^2 because 7^2 = 7*7 = 49.
This means 9x^2 - 49 is the same as (3x)^2 - 7^2. We have a difference of two squares.
The difference of squares factoring rule is
a^2 - b^2 = (a-b)(a+b)
which we have a = 3x and b = 7 in this case
So,
a^2 - b^2 = (a-b)(a+b)
(3x)^2 - 7^2 = (3x-7)(3x+7)
9x^2 - 49 = (3x-7)(3x+7)
Side note: This is the same as (3x+7)(3x-7). We can multiply two numbers in any order.
At a local college, 101 of the male students are smokers and 909 are non-smokers. Of the female students, 270 are
smokers and 630 are non-smokers. A male student and a female student from the college are randomly selected for a
survey. What is the probability that both are non-smokers?
Do not round your answer. (If necessary, consult a list of formulas.)
Answer:
63% Chance
Step-by-step explanation:
Remember, to find the probability of non smokers, we must find the percentage of both male and female non-smokers, and multiply them together.
So lets take all our data from this word problem first. 101 males are smokers, 909 males are not. 270 females are smokers, 630 are not.
Now, to find the percentage of non-smokers, lets add up the total amout of males, and then divide the amount of non-smokers by that number:
909+10=
1010
Ok now we know the total amount of males. Lets divide the amount of non-smokers my 1010:
909/1010
=
0.9
So this shows you that 90% of males are non-smokers.
Now lets do the same with the females:
630+270
=
900
Ok, now we know the total amount of females. Lets divide the amount of non-smoking females by this number:
630/900
=
0.7
Ok, so now we know that 70% of females are non-smokers.
Here is the final step, multipling the numbers together to find the chances of both genders being non-smokers.(I put the percentages back into decimal form when i multiplied)
0.7x0.9
=
0.63
So now we have our answer. We know that there is a 63% chance that the survey will be about 2 nonsmoking male and females.

A rectangular picture is twice as long as it is wide. If the
area of the picture is 288 in^2, what are its dimensions?
The dimensions of the picture are_____ in long by_____ in wide.
Answer:
24 in long by 12 in wide.
Step-by-step explanation:
l=2w
288=(2w)×w
288=2w^2
144=w^2
12=w
use w=12 to solve for l
l=2(12)
l=24
If you place a 36-foot ladder against the top of a building and the bottom of the ladder is 32 feet from the bottom of the building, how tall is the building? Round to the nearest tenth of a foot.
Answer:
16.5
Step-by-step explanation:
36^2-32^2 =272
sqrt272 =16.5
The height of the building is approximately 16.5 feet.
What is the Pythagoras theorem?The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.
Given that, place a 36-foot ladder against the top of a building and the bottom of the ladder is 32 feet from the bottom of the building.
So, hypotenuse of the triangle is 36 feet and base of the triangle is 32 feet.
Let h be the height of the building.
Now, 36²=32²+h²
1296=1024+h²
h²=1296-1024
h²=272
h=16.5 feet
Therefore, the height of the building is approximately 16.6 feet.

A man can row at 9km/h in still water. He rows 1.5km upstream and back again. The stream flows at 3km/h. What is his average speed for the whole trip?
Answer:
8km/h
Step-by-step explanation:
The computation of the average speed is shown below:
In the case of upstream, the speed is
= 9 - 3
= 6km/h
And, the time would be
= 1.5km ÷ 6
= 0.25h
In the case of downstream, the speed is
= 9 + 3
= 12
The time would be
= 1.5km ÷ 12
= 0.125h
Now the average speed is
= 3 ÷ (0.25 + 0.125)
= 8km/h

The measure of an angle is 18°. What is the measure of its supplementary angle?
Answer:
162
Step-by-step explanation:
180 - 18 = 162
A supplementary angle equals 180 degrees
Answer:
72 degrees
Step-by-step explanation:
Supplementary angles are angles that when added together make a right angle, or 90 degrees. So 90-18=72.
