Answer:

$40\frac{5}{8}mm^2$

Step-by-step explanation:

To find the area of a triangle, one must use the formula,

$\frac{base*height}{2}$

It is given that

- base = $9\frac{3}{4}$

-height = $8\frac{1}{3}$

Substitute in the values and solve;

$\frac{9\frac{3}{4}*8\frac{1}{3}}{2}$

In order to multiply the two fractions, one must convert them from mixed number form to improper fraction form. This can be done by multiplying the denominator (the number under the fraction bar), by the "number" part of the mixed number, and then adding the result to the numerator (the number over the fraction bar;

- base = $9\frac{3}{4}=\frac{(9*4)+3}{4}=\frac{36+3}{4}=\frac{39}{4}$

- height = $8\frac{1}{3}=\frac{(8*3)+1}{3}=\frac{24+1}{3}=\frac{25}{3}$

Substitute,

$\frac{\frac{39}{4}*\frac{25}{3}}{2}$

Cross simplify,

$\frac{\frac{325}{4}}{2}$

Further simplify,

$\frac{325}{4}*\frac{1}{2}\\\\= \frac{325}{8}$

Convert back to a mixed number divide the numerator by the denominator, write the whole-number result as the number outside of the fraction, and the remainder as the numerator of the fraction,

$40\frac{5}{8}$

julia can finish a 20-mile bike ride in 1.2 hours. katie can finish the same bike ride in 1.6 hours. how much faster does julia

You can easily find this answer by thinking 1.6-1.2 and since they both have 1 whole you just minus 6-2.

$Use:\\\sqrt[n]{a^m}=a^{\frac{m}{n}}\\\\(a^n)^m=a^{nm}\\\\\left(5^{\frac{3}{4}}\right)^{\frac{2}{3}}=5^{\frac{3}{4}\cdot\frac{2}{3}}=5^{\frac{1}{2}\cdot\frac{1}{1}}=5^{\frac{1}{2}}=\sqrt[2]{5}=\boxed{\sqrt5}$

Travis took out a six-year loan with a principal of $15,000. He made monthly payments of $225 for the entire period, at which po

jeka94

To calculate this you need to multiply 225 by how many months,
6 * 12 = 72,
And so 225 * 72 = $16,200,

To find interest, minus the amount paid by the amount loaned:
16,200 - 15,000 = 1200, so the interest was $1200.

Hope this helps.
