Answer:

36 meters

Step-by-step explanation:

The bird starts at 20 and (assuming it goes up) increases by 16 meters. You have to add to get 36. However, if the bird flies 16 meters down, the answer would be four meters. The answer 36 is assuming the bird flies upward.

Tara is saving for an overseas trip. Her taxable income is usually about $20000. She estimates that she will need $5000 for the

wolverine [178]

An income is taxable is such income falls into a category where a proportion of the income is removed, as tax. To have an extra $5000 after tax, Tara must save $6173.

Given that:

$Earnings = \$20000$ --- normal earnings

$Amount = \$5000$ ---- the amount needed

From the complete question, the tax rate for earnings between $18201 and $37000 is 19%.

Let the additional amount be x.

So, the equation that calculates the amount needed (after tax) is:

$x(1 - 19\%) = 5000$

Express as decimal

$x(1 - 0.19) = 5000$

$x(0.81) = 5000$

Make x the subject

$x = \frac{5000}{0.81}$

$x = \$6173$

Hence, she needs to make an extra of $6173 to save $5000

an aquarium weighs 22.5 lb when empty the aquarium is 30 in long 14 in wide and is filled with water to a depth of 18 in. Water

horrorfan [7]

To get the weight of the aquarium we first calculate the volume of the aquarium.
Volume=(length*width*height)
V=30×14×18
V=7560 in³

But
weight of water is such that for every cubic inches, the weight is 0.036 lb
thus the weight of water will be:
0.036×7560=272.16 lb
Thus the total weight of the aquarium is:
272.16+22.5
=294.66 lb

liubo4ka [24]

Answer:

C). 49.

Step-by-step explanation:

2 - x = 0 gives x = 2.

By the Remainder theorem the remainder here is f(2).

f(2) = 2^4 + 3.2^3 - 2^2 + 2*7 - 1

= 49.
