Turn 276% into a mixed number

1 answer:

6 0

Mixed number is (wholenumber)+(properfraction)
a proper fraction is a/b where a<b and b≠0

so

percent means parts out of 100
x%=x/100

so
276%=
276/100=
200/100+76/100=
2+76/100=
2+38/50=
2+19/25

2 and 19/25

Find tan x if sec x = sort 37/6 and sin x <0

Sveta_85 [38]

Answer:

tan(x) = -1/6

Step-by-step explanation:

We can use the relation between tan and sec:

$\displaystyle\tan{x}=\pm\sqrt{\sec^2{x}-1}\\\\\tan{x}=-\sqrt{\left(\dfrac{\sqrt{37}}{6}\right)^2-1}\quad\text{negative because sine is negative}\\\\=-\sqrt{\dfrac{37-36}{36}}=\boxed{-\dfrac{1}{6}}$

The tangent of x is -1/6.

A plane is flying at 32, 460 feet. To avoid some turbulence, the plane ascends 1645 feet. It then descends 3/5 of its new height

aleksley [76]

Answer: C and E

Step-by-step explanation:

The plane starts at 32,460 feet.

It then ascends 1645 feet. Ascending means it's going up higher. So we add.

32,460 + 1645 = 34,105 (C)

From here (34,105 feet) the plane descends by 3/5 of it's height. Descending means it's lowering. So we subtract.

But first we have to figure out how much we are subtracting.

3/5 is equal to .6

Multiply to find 3/5 of current height.

34,105 × .6 = 20,463

So the plane descends by 20,463 feet.

34,105 - 20,463 = 13,642 feet (E)
