Answer:

E coli bacterium is 200times larger than Rhinovirus

Step-by-step explanation:

Length of a single Rhinovirus is 2×10^-8m

Length of E coli bacterium is 2×10^-6m

This shows that E coli is larger than Rhinovirus.

To determine the number of times the E. coli bacterium is larger than a Rhinovirus, we will divide the length of E coli bacterium by that of single Rhinovirus to have:

2×10^-6/2×10^-8

= 2×10^(-6-(-8))

= 2×10^-6+8

= 2×10²

= 200

This shows that E coli bacterium is 200times larger than Rhinovirus

Find the total cost of a spa treatment of $42 including 6% sales tax and 20% tip
Naily [24]
Cost of the spa treatment = $42
Percentage of sales tax = 6%
Percentage of tips = 20%
Normally the tips amount is calculated before adding sales tax.
Then
Amount of tips given = (20/100) * 42
                                  = (1/5) * 42
                                  = 8.40 dollars
Amount of sales tax taken = (6/100) * 42
                                           = 252/100
                                           = 2.52 dollars
Then 
The total amount spent for spa treatment = (42 + 8.40 + 2.52) dollars
                                                                   = 52.92 dollars
So we can see that $52.92 has been spent in total for spa treatment and this amount includes a sales tax of $2.52 and a tip of $8.40.

The measure of arc LK is?
Oksi-84 [34.3K]

Answer:

Step-by-step explanation:

Because MK is a diameter, then angle L is a right angle. We already know that the measure of angle K is 50, so the measure of angle M has to be 40 because of the triangle angle-sum theorem. The rule for inscribed angles and the arcs they cut off is that the angle is half the measure of its intercepted arc or, likewise, the arc is twice the measure of the angle that cuts it off. Since arc LK is across from angle M and is cut off by angle M, then arc LK is twice the measure of angle M, and is 80. That's the same reason why angle L is 90; arc MK is a semi-circle, with a degree measure of 180, and angle L is half of that.

Arc LK = 80

I need to know how to find the mass and how to get the answer by showing the work.
BigorU [14]
1 ft = 12 in
6 in = 6/12 = 0.5 ft
9 in = 9/12 = 0.75 ft

D = M/V  ⇒  M = DV

V = 0.5 * 0.5 * 0.75 = 0.1875 cubic foot
M = 41.7 * 0.1875 ≈ 7.8 pounds
