ANSWER

The plane will travel

457.2 \: miles.
in 3 hours.


EXPLANATION

It was given that, the plane traveled at a constant speed and covered 762 miles in 5 hours.

So we can write the ratio,

5:762
Let
x
be the distance covered by the plane in 3 hours at the same speed.

Then we can again write the ratio,

3:x


We can now write the proportional relation,

5:762 = 3:x

We rewrite the ratios as fractions to obtain,

\frac{5}{762}  =  \frac{3}{x}

We cross multiply to get,

5x = 3 \times 762



We divide both sides by 5 to get,

x =  \frac{3 \times 762}{5}



x = 3 \times 152.4
This simplifies to,

x = 457.2 \: miles.

I don’t know what to do on here it’s really hard and I need help for the answer
Alla [95]
Ok so our original fraction is:
\frac{36 {x}^{12} }{6 {x}^{9} }
To simplify this fraction, look for instances where the values on the top and bottom can be reduced:

For example, 36 over 6 is the same as 6 over 1, so we can simplify the fraction so it is:
\frac{6 {x}^{12} }{ {x}^{9} }
We can also eliminate the denominator by dividing the nominator by x^9 so:
\frac{6 {x}^{12} }{ {x}^{9} }  \div  \frac{ {x}^{9} }{ {x}^{9} }
= 6 {x}^{3}
And that is the simplified answer of the fraction

Hope this helped

Help fast please ! Match the graph go one of the exponential functions
lara [203]

Answer:

f(x)=(\frac{1}{4} )^{x} +4

Step-by-step explanation:

The way I did this was I noticed that the graph had a y-intercept of 4 and the only exponential function that had a y-intercept of 4 was f(x)=(\frac{1}{4} )^{x} +4

4. For graduation, Diamond was able to buy her first car for $24,000. Her parents gave her a present and made a
s344n2d4d5 [400]

Answer:

$403.15

Step-by-step explanation:

Principal loan amount is the total amount minus down-payment:

Principal=24000-1000\\\\=23000

Knowing that n=12\times 6=72,P=23000, r=7.99\%/12=0.006658, the monthly payments can be calculated using the formula:

M=P[\frac{r(1+r)^n}{(1+r)^n-1}]\\\\=23000\frac{(0.006658(1.006658)^{72}}{1.006658^{72}-1}\\\\=403.15

Hence, the monthly payment is $403.15
