To add fractions, find the LCD - lowest common denominater, and then Combine. answer is 8/9. Decimal form = 0.888888..........
For LCD find where both bottom numbers equal the same so in this case you would have to multiply 3 times 3 to equal 9. Once you do that the 2 thats on top of the 3 will also have to be multiplied by 3 so it could make sense. Now you must Combine - it would be 6/9 +2/9. you only add the top numbers and leave the bottom number.(that is what its out of). Thus the answer is 8/9.

Use slope-intercept form to write the equation of a line

Korvikt [17]

Answer:

y=-3x-2

Step-by-step explanation:

There is enough information to make a point-slope form equation that which we can convert into slope-intercept form.

Point-slope form is: $y-y_1=m(x-x_1)$

We are given the slope of -3 and the point of (1,-5).

$y-y_1=m(x-x_1)\rightarrow y+5=-3(x-1)$

Convert into Slope-Intercept Form:

$y+5=-3(x-1)\\y+5-5=-3(x-1)-5\\\boxed{y=-3x-2}$

Consider a solid spherical ball made of wood. Suppose a hole is bored (drilled) vertically through the center of the ball and th

lbvjy [14]

Answer:

The volume of solid is 268.08 inches cube.

Step-by-step explanation:

The solid spherical ball has height 8 inches that means the diameter of the sphere is 8 inches. So, the radius will be the half of diameter. Thus, radius is 4 inches.

Now use below formula to find the volume of solid sphere.

$Volume = \frac{4}{3}\pi r^{2} \\Volume = \frac{4}{3}\pi (4)^{2} \\Volume = 268.08 \ in^{3}$

Therefore, the volume of solid is 268.08 inches cube.

notka56 [123]

Answer:

Average speed is 48 km per hour

Step-by-step explanation:

A student drove to the university from her home and noted that the odometer reading of her car increased by 16.0 km. The trip took 20.0 min. (a) What was her average speed? in km/hr

Distance traveled is 16 km and the time taken is 20 minutes

convert minutes into hour. to convert minutes into hour we divide by 60 because 1 hour = 60 minutes

$\frac{20}{60} =\frac{1}{3}$

so time = 1/3 and distance = 16

Average speed = distance by time

$speed =\frac{16}{\frac{1}{3} } =\frac{48}{1}= 48$

Average speed is 48 km per hour

A cylindrical water towers has a diameter of 15 meters and a height of 5 meters. About how many gallons of water can the gallon

Artemon [7]

Answer:

233445.54 gallons

Step-by-step explanation:

Given data

Diameter= 15m

Radius= 7.5m

Height= 5m

Let us first find the volume

the volume of a cylinder is given as

V= πr^2h

substitute

V= 3.142*7.5^2*5

V= 3.142*56.25*5

V=883.6875 m^3

Hence the volume in gallons is

233445.54 gallons (from conversion tables)
