1 answer:

7 0

The answer is 78.
The steps:
6[5*(41-36)-(8+4)]
1. 6[5*(5)-(12)]
You do the operations between the parenthesis.
2. 6[25-12]
Follow the order of operations and in this case it's multiplying.
3. 6[13]
Finish what's left between the big parenthesis
4. =78
multiply the last number in between the parenthesis with the number outside and you'll get the answer

What is the arc length of the arc sub tended in a circle with radius 6 and an angle of 7 pi/ 8

KengaRu [80]

Answer:

Formula for the Arc length is given by:

$\text{Arc length} = 2 \pi r \cdot \frac{\theta}{360^{\circ}}$

As per the statement:

radius of circle(r) = 6 units

Angle ( $\theta$ ) = $\frac{7 \pi}{8}$ radian

Use conversion:

$1 rad = \frac{180}{\pi}$

$\frac{7 \pi}{8}$ = $\frac{180}{\pi} \cdot \frac{7 \pi}{8} = \frac{1260}{8} = 157.5^{\circ}$

then;

substitute these given values we have;

Use value of $\pi = 3.14$

$\text{Arc length} = 2\cdot 3.14 \cdot (6) \cdot \frac{157.5^{\circ}}{360^{\circ}}$

$\text{Arc length} = 2\cdot 3.14 \cdot (6) \cdot 0.4375$

Simplify:

$\text{Arc length}=16.485$

Therefore, the arc length of the arc substended in a circle with radius 6 units an angle of 7 pi/8 is 16.485 units

Answer:

m∠DBF = 92°

Step-by-step explanation:

The given statements tell you that points E and F are midpoints of their respective sides of the triangle. Hence EF is parallel to AB and ...

ΔABC ~ ΔEFC

That means ∠DBF ≅ ∠EFC and their measures are 92°.

NEED HELP ASAP!!

devlian [24]

Answer:we multiply by the reciprocal of a fraction when completing a division problem because it is a rule in mathematics that when you divide two fraction, you change the division sign to multiplication and flip the fraction at the right of the multiplication sign.

Step-by-step explanation:

For example if you have 4÷ 1/2. It basically means how many 1/2 can one get in 4. And the answers is 8.

Therefore multiplying by the reciprocal of a fraction when completing a division problem is a short cut method that has been tested and proven to be correct.
