Answer: 105m²

Formula for Area of Circle: A = π r²

so, A = 3.14 (6)² (I got 6 because radius is half the diameter)

Don't forget to divide the final area of the circle in half, because It's only a semicircle.

Formula for Triangle: A = $\frac{bh}{2\\}$

so, A = $\frac{6(8)}{2}$ (again, the "6" is just the diameter divided in half which forms the base of ONE triangle.)

You need to multiply the final area of the triangle by 2 since there are 2 triangles.

In a toy store, the ratio of the number of dolls to the number of teddy bears is . If the store has 240 dolls, how many teddy

forsale [732]

Answer:

So, the way a ratio works is "for every 1 of this, we have 4 of this" for example. (the ratio I just described would be 1:4.)

I believe I've seen this question before. If the ratio of dolls to teddy bears is 9:3 then for every 9 dolls you have 3 teddy bears.

So, since we have 240 dolls and a 9:3 ratio to teddy bears, all we have to do is take how many dolls we have (240) and divide it by 3 to see how many teddy bears we have.

So:

240 ÷ 3 = 80

If your ratio is 9:3, then 80 is your answer.

Hope this helps and have a nice day!

Select all of the following that are quadratic equations.

kifflom [539]

A quadratic equation is one in which the highest exponent of x is 2.
$7x^2+14x=0$ is quadratic; the highest exponent is 2.
x³-3x²+1=0 is NOT quadratic. The highest exponent of x is 3, not 2.
5x-7=0 is NOT quadratic. The highest exponent of x is 1, not 2.
x²+3x-5=0 is quadratic; the highest exponent of x is 2.
x-5=9x+7 is NOT quadratic. The highest exponent of x is 1, not 2.
x²-x=3x+7 is quadratic; the highest exponent of x is 2.

Find the total amount in the compound interest account.

Evgesh-ka [11]

$\bf \qquad \textit{Compounding Continuously Earned Amount}\\\\
A=Pe^{rt}\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to& \$1740\\
r=rate\to 12\%\to \frac{12}{100}\to &0.12\\
t=years\to &5
\end{cases}
\\\\\\
A=1740\cdot e^{0.12\cdot 5}$

bear in mind that the continuously compounding interest is just that, a daily compounding cycle, taking a year as 365days.
