Answer:

Hi there!

The correct answer to this question is: 56.55

Step-by-step explanation:

A semicircle is another way of saying half a circle, if we know the area of a circle is A= π * r^2 then all we have to do is take this equation and divide it by two to get the area of a semicircle. Additionally since we are given the diameter we need to divide that by 2 to get the radius which is six.

Now we can plug all the components into the equation: A= (1/2)(π)(6^2)

you get 56.55

wlad13 [49]

Answer: 76.28 approximately 76

Step-by-step explanation:

Ryan bought fishing gear for 51.50, 14.99 and 5.79.

Total fishing gear bought will be the addition of the 3 fishing gear.

51.50 + 14.99 + 5.79= 72.28

The sales tax is the multiplication of the total fishing gear by 0.05

= 72.28 × 0.05

= 3.614 which is approximately 4

Amount paid by Ryan will be

Total fishing gear + Sales tax

= 72.28 + 4

= 76.28 approximately 76.

What is the sum of ? I will put a pic if the answer is correct ill mark brainlist

$\text{The sum of } 1\frac{7}{10} \text{ and } 3\frac{3}{5} \text{ is } 5\frac{3}{10}$

Solution:

Given that we have to find the sum of $1\frac{7}{10} \text{ and } 3\frac{3}{5}$

Let us first convert the mixed fractions to improper fractions

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator

Therefore,

$1\frac{7}{10} = \frac{10 \times 1 + 7}{10} = \frac{10+7}{10} = \frac{17}{10}\\\\3\frac{3}{5} = \frac{5 \times 3 + 3}{5} = \frac{18}{5}$

Now we can add both the fractions

$1\frac{7}{10} + 3\frac{3}{5} = \frac{17}{10} + \frac{18}{5}$

Make the denominators same

$1\frac{7}{10} + 3\frac{3}{5} = \frac{17}{10} + \frac{18 \times 2}{5 \times 2}\\\\1\frac{7}{10} + 3\frac{3}{5} = \frac{17}{10} + \frac{36}{10}\\\\\text{Add the fractions since the denominator is same }\\\\1\frac{7}{10} + 3\frac{3}{5} = \frac{17+36}{10} = \frac{53}{10}$
