Answer:

18 are goldfish.

Step-by-step explanation:

75%=3/4, divide 24 by 4 and you get 6, multiply 6 (because THREE 2/4 quarters) and you get 18. Therefore, there are 18 goldfish.

Please help me simplify these expressions

Archy [21]

Answer:

Step-by-step explanation:

If base of variable is same, add the powers

1) x² * x * x³ * x⁵ = x²⁺¹⁺³⁺⁵ = x¹¹

2) -2n² * -n⁴ * 5n³ = (-2* -1* 5 ) *n²⁺⁴⁺³ = 10n⁹

3)-3x⁴ * 2x⁵ * - x = (-3 * 2 * -1)* x⁵⁺⁴⁺¹ = 6x¹⁰

Could some one plz help me with this question

zhuklara [117]

Answer:

Step-by-step explanation:

The formula for this type of interest is $A=P(1+\frac{r}{n})^{nt}$ , where A is the total amount, P is the initial investment, x is the interest rate, n is the amount of times that the investment is compounded a year, and t is the amount of years. Plugging in the numbers given, you get:

$A=1800(1+\frac{0.025}{2})^{2\cdot 12}=$

$1800(1.0125)^{24}\approx 2425.23$

Now, she invests this into a new account, and you can set up the following equation:

$A=2425.23(1+\frac{0.04}{12})^{12\cdot 7}=$

$2425.23(1.0033333)^{84}\approx 3207.40$ , or option A.

Hope this helps!

Jimmy was supposed to multiply a certain number by 43 but by mistake he multiplied that number by 34 as a result his answer was

vredina [299]

Answer:

345

Step-by-step explanation:

We can solve this problem by two equations. Our variables will be the following:

$x$ is the amount to be multiplied

and $y$ is the amount that should be obtained by multiplying by 43

Thus our first equation is:

$43x=y$

But the problem tells us that there was an error and the number $x$ was multiplied by 34, so the result failed by 3105, thus the second equation is as follows:

$34x=y-3105$

By multiplying the quantity by 34, an amount is obtained that differs from 3105 from what it would have been obtained if multiplied by 43.

Now we are going to replace the first equation in the second one ( $y=43x$ ):

$34x=43x-3105$

And clear to find x:

$3105=43x-34x\\3105=9x\\\frac{3105}{9}=x\\345=x$

The number that jimmy was supposed to multiply by 43 is 345.
