Answer:

-1/6

Step-by-step explanation:

= 1/3 (-1-1) x -1/4 (-1)

= 1/3 (-2) x 1/4

= -2/3 x 1/4

= -2\12

2 and 12 can cancel out each other.

so the answer will be.

= -1/6.

If xh=10 feet and mxy =100 degrees then determine the arc length of xy

schepotkina [342]

Answer:

The arc length XY is equal to $\frac{50}{9}\pi\ ft$ or $17.4\ ft$

Step-by-step explanation:

The picture of the question in the attached figure

step 1

Find the circumference of the circle H

The circumference is given by the formula

$C=2 \pi r$

we have

$r=xh=10\ ft$

substitute

$C=2 \pi (10)\\C=20\pi\ ft$

step 2

we know that

The circumference of a circle subtends a central angle of 360 degrees

using proportion

Find out the length of the arc xy if the central angle is equal to 100 degrees

Remember that

$m\angle XHY=arc\ XY=100^o$ ---> by central angle

$\frac{20\pi}{360^o}=\frac{x}{100^o}\\\\x=20\pi(100)/360\\\\x=\frac{2,000}{360}\pi\ ft$

Simplify

$x=\frac{50}{9}\pi\ ft$ ----> exact value

To find out the approximate value

assume

$\pi=3.14$

substitute

$x=\frac{50}{9}(3.14)=17.4\ ft$ ----> approximate value

therefore

The arc length XY is equal to $\frac{50}{9}\pi\ ft$ or $17.4\ ft$

How do you write out 3 1/4 times 24

solmaris [256]

The answer is 28 because 1/4 is equivalent to .25 so 3.25 x 24 equals 28.

Find the slope please

scoray [572]

The slope of the line is 2.

The slope is going up from left to right, so it'll be positive to start with. From there you have to do rise over run. That is pretty much how many units up and in towards the slope do you have to go until you find 2 points that are in the center of the line. In this case, the rise over run is 2/1 which equals 2.

May I have brainliest please? :)

Ben's teacher wants him to write a 3 digit number that uses the 3 once and a 6 twice. The value of one of the 6 needs to be 1/10

pantera1 [17]

Ben can write the number 366 or 663. There is one three and two sixes. One of each six is greater than the other 6 times 10.

On a bike ride across the United States, Rodney rides 190 miles every 4 days. If he continues at this rate, how many miles can h

Gwar [14]

190÷4= 47.5
47.5 is how many miles a day Rodney is traveling
190+47.5+47.5 = 285
