First we have to find the decimal equivalent by dividing.
5 / 8 = 0.625

It can't be an Integer because decimals can't be intergers, so that's ruled out

It can't be repeating as it does end, so that's also ruled out

Since the decimal does end it can't be non-terminating, non-repeating

So the answer is Terminating Decimal by process of elimination

A force of 9 lb is required to hold 35lb crate on a hill. What angle does the hill make with the horizontal?

kenny6666 [7]

Answer: $14.9^{\circ}$

Step-by-step explanation:

Given

Applied force is 9 lb to hold of 35 lb crate on a hill

Suppose the hill makes an angle of $\theta$ with horizontal

There will be two component of weights i.e. along and perpendicular to the hill

Only the component along the hill pulls the crate backwards

So,

$\Rightarrow 35\sin \theta=9\\\\\Rightarrow \sin\theta =\dfrac{9}{35}\\\\\Rightarrow \theta =14.89^{\circ}\approx 14.9^{\circ}$

If f(x)=x^2 and g(x)=1/2x+3 find g(f(-1))

telo118 [61]

Answer:

1/5

Step-by-step explanation:

F(x)=x^2

g(x)=1/(2x+3)

g(f(-1))=?

x=-1→f(-1)=(-1)^2→f(-1)=1

g(f(-1))=g(1)=1/[2(1)+3]=1/(2+3)→g(f(-1))=1/5

The gross federal debt y (in trillions of dollars) for a certain country in year x is approximated by the following equation,

miskamm [114]

Answer: 2008

Step-by-step explanation:

Given : The gross federal debt y (in trillions of dollars) for a certain country in year x is approximated by the equation $y =1.18x +1.58$ , where x is the number of years after 2000.

To find the year in which the federal debt will be $10.68 trillion, we substitute y= 10.68 in the above equation , we get

$10.68 =1.18x +1.58\\\\\Rightarrow\ 1.18x=10.68-1.58\\\\\Rightarrow\ 1.18x =9.1\\\\\Rightarrow\ x=\dfrac{9.1}{1.18}=7.7118644067\approx8$

The required year will be = 2000+8=2008.

Hence, in 2008 the federal debt will be $10.68 trillion.

Which variable will you choose to eliminate? How?

Inga [223]

Answer:

Variable elimination

8x+3y=-7
3y=-8x-7
y=-8/3x-7/3

Now plug it into y
7x-16/3x-14/3=-3
5/3x-14/3=-3
5/3x=5/3
x=1

Answer: perimeter = 302m

area = 5544m^2

Step-by-step explanation:

perimeter = 2(l + b)

= 2(63 + 88)

= 2 x 151

= 302 m

Area = l x b

= 88 x 63

= 5544 m^2

Hope it helped u,

pls mark as the brainliest
