Find the area of the larger sector.
Round to the nearest tenth.
2559
13.4 miles
Area = [ ? ]miles2
Enter
Step-by-step explanation:
the formula for the area of a sector is
(x°(r^2)π)/360
with x being the angle
r bring the radius of the circle
(255(13.4)^2π)/360
399.6
Hope that helps :)
Answer:
The answer is 399.6 not 399.4. I put 399.6 as my answer on acellus and I got it right.

Solve using elimination. 9x − 9y = –18 10x − 9y = –13
Answer:
y = 5, y = 7
Step-by-step explanation:
can I get a solution
[tex] \sqrt{x - 1} - 3 = 0[/tex]
is this solution correct or not can you please give me the following steps for this solution by solving for x if possible
Answer:
I don't think it is correct.
Step-by-step explanation:
Square root just means half of a number. If you square this number, it just goes back to it's original form, just without the square root sign. But however, You must square the 10 at the end of the equation as well. This solution is not correct.
Verify the equation: (tan x - 1)/(tan x + 1) = (1 - cot x)/(1 + cot x)
Answer:
True.
Step-by-step explanation:
given equation: (tan x - 1)/(tan x + 1) = (1 - cot x)/(1 + cot x)
1. manipulate the right side by using trigonometric identities
(tan(x) - 1)/(tan(x) + 1) = (-cos(x) + sin(x))/(cos(x) + sin(x))
2. manipulate the right side by using trigonometric identities
(-cos(x) + sin(x))/(cos(x) + sin(x)) = (-cos(x) + sin(x))/(cos(x) + sin(x))
Both sides of the equation are now equal -> (tan x - 1)/(tan x + 1) = (1 - cot x)/(1 + cot x) is true.

A running track consists of two parallel lines that are connected at each end but the curved boundary of a semicircle. The parallel lines are 30 meters long and 7 meters apart. Fine the area inside the running track.
Answer:
The area inside the running track is 248.5 m².
Step-by-step explanation:
The area inside the running track is given by the sum of the area of a rectangle and the area of a semicircle:
[tex] A_{t} = A_{r} + 2A_{c} [/tex]
[tex] A_{t} = x*(2r) + 2*(\frac{\pi r^{2}}{2}) [/tex]
Where:
x: is one side of the rectangle = 30 m
r: is the radius = half of the other side of the rectangle = 7/2 m = 3.5 m
Hence, the total area is:
[tex] A_{t} = 30*7 + \pi (3.5)^{2} = 248.5 m^{2} [/tex]
Therefore, the area inside the running track is 248.5 m².
I hope it helps you!
Someone please help me I’ll give out brainliest please dont answer if you don’t know
First use the distributive property by multiplying the 3 with each term inside the parentheses:
-8 + 3c + 3 + c
Now combine like terms:
-8 + 3 = -5
3c + c = 4c
Combine for final answer:
-5 + 4c which can also be written as 4c-5
Answer:
first let's multiply 3 by the bracket
-8+3*c+3*1+c=-8+3c+3+c
then add the numbers that have the same variables -8+3+3c+c
=-8+3+4c then add the numbers
=-5+4c is the answer
you can also write it like this
4c-5
Please help if you would want brianleist!! :D ^^
Answer:
384
Step-by-step explanation:
v= L x W x H
v= 4 x 2 x 1.2
v= 9.6
9.6 x 40 = 384
lmk if you have any questions :)
Answer:
A
Step-By-Step Explanation:
Step One: The first step is to figure out the volume of one. The volume formula is length times width times height. We have all the dimensions so: 4 times 2 times 1.2= 9.6.
Step Two: Now, we just mutiply the number by 40 since there are 40 slabs: 384.
