Answer:
x = 40
Step-by-step explanation:
measure of the angles = 1/2( outside arc - inside arc)
x/2 = 1/2[x + 70 - (x + 30)]
x/2 = 1/2 ( x + 70 - x - 30)
x/2 = 1/2 (40)
2(x/2) = 2(1/2)(40)
x = 40
Step-by-step explanation:
did you make a typo, or do you actually mean dm ?
1 dm = 10 cm
in any case, in a right prism object it does not matter what shape the bases are.
the volume is always
base area × height
so, if you did not make a typo, then
height = 2.3 dm = 23 cm
and the volume of the prism is
44 × 23 = 1012 cm³
but if you did make a typo and
height = 2.3 cm,
then the volume of the prism is
44 × 2.3 = 101.2 cm³
Answer:
D
Step-by-step explanation:
<span>(2a + 2) / (a^2 – 1)
(2(a +1)) / (a^2 - 1)
(2(a + 1)) / (a^2 - 1^2)
(2(a + 1)) / ((a + 1)(a - 1))
2 / a - 1
The answer is: 2/a - 1.</span>
Answer:
x=2
Step-by-step explanation:
2.1(2.3 + 2.1x) = 11.65 + x
Distribute
4.83+4.41x=11.65+x
bring 4.83 over (-)
4.41x=6.82+x
bring x over
4.41x-1(x)=6.82
4.41-1=3.41 so
3.41x=6.82
divide 3.41
x=2
