Subtract and reduce

juin [17]

Your equation is the following:
11 7/7 - (-8 3/7)
the first step to solving this is to know that when there is a "-" sign in front of the parenthesis, you need to change the sign of each term in the parenthesis.
11 7/7 + 8 3/7
now, add the whole numbers and the fractional parts of the mixed numbers separately.
(11 + 8) + ( $\frac{7}{7} + \frac{3}{7}$ )
add the whole numbers together
19 + ( $\frac{7}{7} + \frac{3}{7}$ )
now add the fractions together
19 + 10/7
next, convert the improper fraction to a mixed number
19 + 1 3/7
now, you will write the mixed number as a sum of the whole number and its fractional part.
19 + 1 + 3/7
add the numbers together
20 + 3/7
finally, write the sum of the whole number and the fraction as a mixed number
20 $\frac{3}{7}$
let me know if you have any further questions

Given: Quadrilateral ABCD is inscribed in circle O.

Airida [17]

1. Quadrilateral ABCD is inscribed in circle O
A quadrilateral is a four sided figure, in this case ABCD is a cyclic quadrilateral such that all its vertices touches the circumference of the circle.
A cyclic quadrilateral is a four sided figure with all its vertices touching the circumference of a circle.

2. mBCD = 2 (m∠A) = Inscribed Angle Theorem
An inscribed angle is an angle with its vertex on the circle, formed by two intersecting chords.
Such that Inscribed angle = 1/2 Intercepted Arc
In this case the inscribed angle is m∠A and the intercepted arc is MBCD
Therefore; m∠A = 1/2 mBCD

4. The sum of arcs that make up a circle is 360
Therefore; mBCD + mDAB = 360°
The circles is made up of arc BCD and arc DAB, therefore the sum angle of the arcs is equivalent to 360°

5. 2(m∠A + 2(m∠C) = 360; this is substitution property
From step 4 we stated that mBCD +mDAB = 360
but from the inscribed angle theorem;
mBCD= 2 (m∠A) and mDAB = 2(m∠C)
Therefore; substituting in the equation in step 4 we get;
2(m∠A) + 2(m∠C) = 360

What is the area of a sector with a central angle of 3pi/5 radians and a diameter of 21.2cm

Elenna [48]

Answer: 105.84 cm^2

To find the answer, first you have to start by finding the percent of the circle in the sector. Convert the radians given to 108 degrees. 108 out of 360 is 30%.

Now, find the area of the circle. It's pi x r^2, so the area is 352.810.

Multiply this by 30% to find our area of 105.84 cm^2

You've decided to go cave diving. the route between a and b in 8025 meters long and the average diver can swim 15 meters per min

Anastasy [175]

$\text{The route between A and B is 8025 meters.}\\
\\
\text{And an average diver can swim 15 meters per minute.}\\
\text{we need to find the time it will take to complete diving.}\\
\\
\text{by the time distance formula, we know that}\\
\\
\text{Time}=\frac{\text{Distance}}{\text{Speed}}\\
\\
\text{so using this the time taken to complete the dive is}\\
\\
\text{Time}=\frac{8025}{15}\\
\\
\Rightarrow \text{Time}=535 \text{ minutes}$

So the time taken to complete the dive is: 535 minutes
