Answer:
4.77
if u use 3 for pie its 5
Step-by-step explanation:
formula is d=c/pie
so d=15/pie
d=4.77
40% percent times 70 is want I believe
Answer:
![Area \approx 1149\ cm^2](https://tex.z-dn.net/?f=Area%20%20%5Capprox%201149%5C%20cm%5E2)
Step-by-step explanation:
<u>Given that:</u>
ΔUVW,
Side w = 44 cm, (It is the side opposite to
)
Side u = 83 cm (It is the side opposite to
)
and ∠V=141°
Please refer to the attached image with labeling of the triangle with the dimensions given.
Area of a triangle with two sides given and angle between the two sides can be formulated as:
![A = \dfrac{1}{2}\times a\times b\times sinC](https://tex.z-dn.net/?f=A%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%20a%5Ctimes%20b%5Ctimes%20sinC)
Where a and b are the two sides and
is the angle between the sides a and b
Here we have a = w = 44cm
b = u = 44cm
and ∠C= ∠V=141
Putting the values to find the area:
![A = \dfrac{1}{2}\times 44\times 83\times sin141\\\Rightarrow A = \dfrac{1}{2} \times 3652 \times sin141\\\Rightarrow A =1826 \times 0.629\\\Rightarrow A \approx 1149\ cm^2](https://tex.z-dn.net/?f=A%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%5Ctimes%2044%5Ctimes%2083%5Ctimes%20sin141%5C%5C%5CRightarrow%20A%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%20%5Ctimes%203652%20%5Ctimes%20sin141%5C%5C%5CRightarrow%20A%20%3D1826%20%5Ctimes%200.629%5C%5C%5CRightarrow%20A%20%20%5Capprox%201149%5C%20cm%5E2)
So, the <em>area </em>of given triangle to the nearest square centimetre is:
![Area \approx 1149\ cm^2](https://tex.z-dn.net/?f=Area%20%20%5Capprox%201149%5C%20cm%5E2)
Answer:
( 7 , 4 )
given:
make y the subject in equation 2:
4x - y = 24
-y = 24 - 4x
y = 4x - 24
insert this in equation 1:
4x + 10y = 68
4x + 10(4x - 24) = 68
4x + 40x - 240 = 68
44x = 68 + 240
44x = 308
x = 7
solve for y:
y = 4x - 24
y = 4(7) - 24
y = 4
Answer:
C
Step-by-step explanation:
Since "P" is -4, add POSITIVE 6.5 to it. It makes 2.5
hope it helps :D
