5. Find the surface area of the cone. Round to<br> the nearest hundredth.<br> 2 ft<br> 6 ft

den301095 [7]

Answer:

$52.3m^2$

Step-by-step explanation:

Use these formulas

$A=\pi rl+\pi r^2\\l=\sqrt{r^2+h^2}$

Now solve

$A=\pi r(r+\sqrt{h^2+r^2} )\\=\pi *2*(2\sqrt{6^2+2^2} )\\=52.3m^2$

Andrew is paid $4 per hour for the first 30 hours he works each week. He makes $5 per hour for each hour he works over 30 hours

rusak2 [61]

Answer:

f(w) = 120 + 5(30-h)

Step-by-step explanation:

It is given that, Andrew gets paid $4 for first 30 hours of the week

So,

For first 30 hours, his wage will be:

4(30) = $120

Now, let w denote wages and h denote total number or hours he works in the week

So he will be paid $5 for h-30 hours

So the function will be

f(w) = 120 + 5(30-h)

Where $120 is the fixed income for first 30 hours and the second term is the wage of hours more than 30 at the rate of $5 per hour..

Add 7/8 + 2 3/24 + 6 1/6

natali 33 [55]

Answer:

9 4/24 or 9 1/6

Find the LCM(lowest common multiple) of 8, 24 and 6.
The LCM of 8, 24 and 6 is 24.
We now want to turn all the denominators into 24 so we are going multiply 7/8 by 3 and 1/6 by 4. We won't need to turn the denominator of 3/24 into 24 because it's already 24
Whatever you do to the denominator you have to do to the numerator, so you also have to multiply the numerator of 7/8 by 3 and the numerator of 1/6 by 4
That now results in 21/8 + 2 3/24 + 6 4/24
Now you have to add all the fractions together which is going to equal to 28/24
Because 28/24 is more than the whole, subtract 28 from 24 which gives us 4. That 4 is now our new numerator
We are now going to all the whole numbers 6+2+1=9. Incase you're wondering, the '1' came from the 28/24
The answer you should get should be 9 4/24 or if it should be simplified it would be 9 1/6

A line passes through (0,4) and (3,0). Which equation does not represent the equation of this line?

Olenka [21]

Answer:

Step-by-step explanation:

use both points to find the slope using the equation

y2-y1/x2-x1, so , -2-4/2-0 = -6/2 = -3. slope or m = -3

then the y int can be any y point, so either -2 or 4. in this case they used 4.
