Answer:

y= $\frac{x+9}{n}$

Step-by-step explanation:

x/y=n-9

x= y(n-9)

x= yn-9n

-yn= -x-9n

yn= x+9n

y= $\frac{x+9}{n}$

A person invests 9000 dollars in a bank. The bank pays 6% interest compounded monthly. To the nearest tenth of a year, how long

il63 [147K]

Answer:

$7.4\ years$

Step-by-step explanation:

we know that

The compound interest formula is equal to

$A=P(1+\frac{r}{n})^{nt}$

where

A is the Final Investment Value

P is the Principal amount of money to be invested

r is the rate of interest in decimal

t is Number of Time Periods

n is the number of times interest is compounded per year

in this problem we have

$t=?\ years\\ P=\$9,000\\ r=0.06\\n=12\\ A=\$14,000$

substitute in the formula above

$14,000=9,000(1+\frac{0.06}{12})^{12t}$

$(14/9)=(1.005)^{12t}$

Apply log both sides

$log(14/9)=(12t)log(1.005)$

$t=log(14/9)/[(12)log(1.005)]$

$t=7.4\ years$

A kite flying in the air has a 10-ft line attached to it. It’s line is pulled taut and casts a 7-ft shadow. Find the height of t

jasenka [17]

Answer:

If the kite has an 11 ft line attached to it and it casts an 8 feet shadow, we will have a rectangle triangle (see picture below).

To find the height x of the kite, we can apply the Pythagorean theorem.

x² = 11² - 8²

x² = 121 - 64

x² = 57

x =√57 Step-by-step explanation:

How do you solve 14p−8=22+20p ?

Zanzabum

The value of p is -5

Simply use cross multiplication :

The process of multiplying numbers in the shape of a fraction is called cross multiplication. Cross multiplying, also known as cross multiplication, is the process of multiplying the numerator of one fraction by the denominator of the other fraction on the other side of an equal symbol. Cross multiplication is a method for comparing fractions.

Both fractions with like and unlike parts are multiplied across. When employing the cross-multiplication procedure, we multiply the denominators as well as the numerators when a fraction is dissimilar, or when the denominators of two fractions are not alike.

$14p-8=22+20p\\or, 14p-20p=22+8\\or, -6p=30\\or, p=-\frac{30}{6} \\or, p= -5$

NEED HELP FAST!!!! will mark u as brainliest

Obviously, it's not rational, because it's the sum of two square roots, so cancel out A and B right away.

If we solve it

sqrt (18) + sqrt (2)
= sqrt (9*2) + sqrt (2)
= 3 sqrt (2) + sqrt (2)
= 4 sqrt (2)
