Answer:
3.14 cm
Step-by-step explanation:
From the question,
Applying
s = πdФ/360................... Equation 1
Where s = length of arc AB, d = diameter of the circle, Ф = angle at the center of the circle, π = pie
From the question,
Given: d = 8 cm, Ф = π/4 rad = 45°
Constant: π = 22/7
Substitute these values into equation 1
s = (22/7)(8)(45)/360
s = 3.14 cm.
Hence the lenght of arc AB = 3.14 cm

Step-by-step explanation:
Victor is selling lemonade to raise money for his school.the amount of money he collected from his school. the amount of money he collected from his sales each day is summarized on the box plot below
The question is incomplete. The complete question is :
Victor is selling lemonade to raise money for his school. The amount of money he collected from his sales each day is summarized on the box plot below.
What is the interquartile range of the data ?
Answer:
$ 7
Step-by-step explanation:
It is given that Victor sold lemonade in order to raise money for his school.
The money that Victor collected is shown on the diagram below.
Therefore, we find the interquartile range. It is the difference between the 3rd quartile and the 1st quartile, i.e.
IQR = [tex]$Q_3-Q_1$[/tex]
Now from the figure, the 3rd quartile is the value that is at the end of the rectangular box towards the right. Therefore, the 3rd quartile is = $ 29
Similarly from the figure the 1st quartile at the beginning of the rectangular box to the left is = $ 22
So the interquartile range is = 3rd quartile - 1st quartile
= 29 - 22
= $ 7
Thus the amount of money Victor collected is $ 7.

Step-by-step explanation:
Savannah has a package of 20 candies with an equal number of candies colored white, blue, orange, purple, and yellow. If Savannah selected a yellow candy the first time, what is the
probability that she will randomly select, without replacement, another yellow candy?
A 3/19
B 1/5
C 4/19
D 1/4
Answer:
A 3/19
Step-by-step explanation:
There are 4 candies of each color. If you take out one yellow, you not only have three yellows; you have 19 candies. 3/19 is the answer.
Answer:
3/19
Step-by-step explanation:
There is an equal number of colored candies, in which there are 20 candies in all, and 5 colors:
20/5 = 4
Each color has 4 candies.
Savannah was able to obtain a yellow candy, and she does not replace it:
4/20 removing one yellow candy = 3/19
A) 3/19 is her chance of getting another yellow.
your resturaunt bill is 42$ you want to leave a 15% tip, what should the tip be
Answer:
$6.30
Step-by-step explanation:
Answer:
The tip should be $6.30
Step-by-step explanation:
We can find 15 percent of 42$ by multiplying 42 by 0.15 (this is another way of writing down 15%) and so we get...
(42)(0.15) = 6.3
Therefore the tip should be $6.30

Twins issac and isaiah were just born issac weighs 6 pounds 2 ounces and isaiah weighs 5 pounds 4 ounces.How many ounces do issac and isaiah weigh together?
Answer: [tex]11\ \text{pounds}\ 6\ \text{ounces}[/tex]
Step-by-step explanation:
Given
Issac and Isaiah born weighing 6 pounds 2 ounces and 5 pounds and 4 ounces.
1 Pound is equivalent to 16 ounces
Issac weighs
[tex]\Rightarrow 6+\dfrac{2}{16}\ \text{Pounds}[/tex]
Isaiah weighs
[tex]\Rightarrow 5+\dfrac{4}{16}\ \text{Pounds}[/tex]
Their combined weight is
[tex]\Rightarrow 6+5+\dfrac{2}{16}+\dfrac{4}{16}\\\\\Rightarrow 11+\dfrac{6}{16}\ or\\\\\Rightarrow 11\ \text{pounds}\ 6\ \text{ounces}[/tex]

The circumference of a circle is 100.48 feet. What is the circle's diameter?
Answer:
631.334460 ft
Step-by-step explanation:
i think
Answer:
32 feet
Step-by-step explanation:
Since we know that the formula for finding circumference is C = π · d, and π is equal to 3.14, we reverse the formula so it fits what information we have.
We know that C = 100.48 and we also know that π = 3.14 so all we have to find is the diameter.
To do this, you divide 100.48 by 3.14 to get 32 feet as your final answer.
(a) An angle measures 50°. What is the measure of its complement?
(b) angle measures 32°. What is the measure of its supplement?
Answer:
a) 40 degrees b) 148 degrees
Step-by-step explanation:
a) Complementary angles are angles that in total measure 90 degrees, or form a right angle. If one angle is 50 degrees, then 90 - 50 = 40, meaning the measure of its complement will be 40 degrees.
b) Supplementary angles are similar but in total measure 180 degrees, or form a straight angle. If one angle measures 32 degrees, then 180 - 32 is equal to 148, meaning the measure of its supplement will be 148 degrees.

I think of number, double it and add 11. I get 25 a) using the statement above, form an equation. Use the letter 'x' as a unknown number b) solve the equation
Answer:
x = 7
Step-by-step explanation:
Let
x = the unknown number
double it :
2x
add 11:
2x + 11
I get 25:
The equation is
2x + 11 = 25
2x = 25 - 12
2x = 14
Divide both sides by 2
x = 14/2
x = 7

Bus A and Bus B leave the bus depot at 3 pm.
Bus A takes 25 minutes to complete its route once and bus B takes 30 minutes to complete its route once.
If both buses continue to repeat their route, at what time will they be back at the bus depot together?
Assume the buses have no breaks in between routes.
Give your answer as a 12-hour clock time.
Answer:
5:30 pm.
Step-by-step explanation:
First find the LCM (lowest common multiple) of 25 and 30. This is the amount of minutes it will take for the buses to meet again.
25 can be broken up into 5*5
30 can be broken up into 5*6
The most amount of 5s found in a number is two times in 25 and the most amount of 6s found in a number is once in 30, so
25*6=150
150 is the LCM. This means that in 150 minutes, the buses will be back at the bus depot together.
All we have to do now is convert 150 minutes to hours.
One hour is 60 minutes, so 150/60 is 2.5 hours, or 2 hours and 30 minutes.
2 hours and 30 minutes after 3 pm is 5:30 pm.

Estimate 16.82-8.264 by first rounding each number to the nearest tenth.
pls help i need the right answer!
Answer:
about 8.40
Step-by-step explanation:
16.82-8.264
Rounding 16.82
look at the hundredths place and determine if it is greater than or equal to 5. If so round up. If not, leave it the same. Since 2 is not greater than or equal to, we can estimate 16.80.rounding 8.264
6 is above 5, so we can round 2 to 3. making 8.364.estimate 8.4016.80-8.40=8.40
Angles: Arcs & Angles need help thank you!!
Answer:
See answers below
Step-by-step explanation:
1) The typr of triangle in a semicircle is a right angle. Hence the measure of m<ABC is 90degrees
2) m<DEF = 1/2(144)
m<DEF = 144/2
m<DEF = 72degrees
3) From the trinagle
4x+3 + x+7 +90 ==180
5x + 100 = 180
5x = 180-100
5x = 80
x = 80/5
x = 16
<QRD = x+7
m<QRD = 16 + 7
m<QRD = 23degrees
4) Angle in the same segment are equal
5x-37= 3x+1
5x - 3x = 1+37
2x = 38
x = 38/2
x =19

The volume of two similar solids are 128 m3
and 250 m². The surface area of the larger
solid is 250 m². What is the surface are of the
smaller solid?
Answer:
Solution given:
The volume of two similar solids are 128 m³
and 250 m³.
surface area of larger solid is 250m²
let surface area of smaller solid be x.
Since they are similar
[tex] \frac{250}{128} = \frac{250}{x} [/tex]
x=128
the surface are of the
smaller solid is 128m²

Find the value of x.
a) 80
b) 90
c) 45
d) 60
Answer:
b
Step-by-step explanation:
The tangent- tangent angle x is half the difference of its intercepted arcs.
Th sum of the arcs in a circle = 360°
major arc = 360° - 90° = 270° , then
x = [tex]\frac{1}{2}[/tex] (270 - 90)° = [tex]\frac{1}{2}[/tex] × 180° = 90° → b
