If the radius is 21 cm and the angle at
center of circle is 140° then the length of
the arc is ?
Step-by-step explanation:
Given: Radius , r =21 cm
The angle at the center of the circle, n° =140°
Length of an arc =?
W.K.T Formula, Length of an arc = 2πr( n°÷360°) units
= 2*(22/7)*21*(140°/360°)
= 154/3
= 51.33cm
Answer:
2*(22/7)*21*(140°/360°)
= 154/3
= 51.33cm

The enrollment at a university increased from 16,000 students to 20,000 students over a period of 5
years. What is the percent increase in enrollment?
difference
net/
Answer:
25%
Step-by-step explanation:
Initial no of students = 16,000
Final no of students = 20,000
We need to find the percent increase in enrollment.
The increase in no of students = 20,000 - 16,000
= 4000
Percentage = (increase/initial no of students) × 100
[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]
Hence, the percent increase is 25%.
There are 3 times as many dogs as cats.
If the total number of dogs and cats is 16, how many dogs are there?
Answer:
there are 12 dogs.
Step-by-step explanation:
d= dogs now plug in the 4 into your equation.
c= cats d=3(4)
d+c=16 d=12
3c+c=16
4c=16 SO THEREFORE THERE ARE 12 DOGS :)
c=4

The base of a 15 foot ladder is 9 feet from a building. The top of the leaning ladder reaches and makes contact with the building’s roof. On the corner of the building, a 6 foot flagpole is erected on the roof. What is the height from the base of the building to the top of the flagpole? Please show your work.
9514 1404 393
Answer:
18 feet
Step-by-step explanation:
The ladder length represents the hypotenuse of a right triangle with a base of 9 and an unknown height (h). We can find that height by using the Pythagorean theorem.
9² +h² = 15²
h² = 225 -81 = 144
h = √144 = 12
So, the ladder extends 12 feet up the side of the building. That is the height of the roof. The top of the flagpole is 6 feet above that, so the top of the flagpole is ...
12 ft + 6 ft = 18 ft
above the ground.
The height to the top of the flagpole is 18 feet.

what is the solution of sqaure root -4x = 100
Answer:
I’m pretty sure it’s -2500
Step-by-step explanation:
Answer:
I think it would be x = -2500
Step-by-step explanation:
You square both sides to get rid of the square root and get -4x = 10000 then divide 10000 by -4 to get -2500

What is the y-intercept of the line?
It crosses the y axis at 4... it is 4 :)
Answer:
a. (0, 4)
General Formulas and Concepts:
Algebra I
The y-intercept is the y value when x = 0. Another way to reword that is when the graph crosses the y-axis.Step-by-step explanation:
According to the graph, the line crosses the y-axis at y = 4. Therefore, our y-intercept is 4. Writing it in coordinate point would be (0, 4), as definition of the y-int.

Please help UwU
also hope your day is going GREAT
if correct i will give BRAINIEST
Answer:
b bro and u get a good day too
Answer:
Pretty sure its C >:]
Explanation:
It's the third option because if you put a piece of paper in the corner its a lil more than 90 degrees, so it wouldn't be B (there's a little more white space left). And it obviously wouldn't be A because that's self explanatory, lol.
And you can't make a perfect square in the inside of the angle so that's another way to tell.
Extra:
I hope you have an amazing day too,, you seem very nice ^-^ good luck on your schoolwork today :]

Step-by-step explanation:
Its asking for how long did she watch for both videos.
[tex] \frac{3}{8} + \frac{1}{8} = \frac{4}{8} [/tex]
4/8 is half. so simplest form would be
[tex] \frac{1}{2} [/tex]
Answer:
1/2 minutes
Step-by-step explanation:
you add the two fractions together and because they have a common denominator you just add across.
1/8+3/8=4/8
now we simplify
the numerator and denominator can both be divided by 4.
4÷4=1
8÷4=2
1/2
