Can someone please help me?

Ok so their are 36 people that didn't need gel for there hair. so when you multiply 36 x 5 (because each cut costs 5 bucks) you get an answer of 180. so hold on to that and since their are 16 people that asked for gel you would need to first multiply 5 and 10% which gives you 0.5 so when you multiply 5.5 (because when you multiplied the 10% with the 5 you should get .5) times 16 you should get an answer of 88. when you add 180 with 88 you get an answer of 268. Ur welcome couuld u mark this brainlist plzzzzz

During the cold winter months, a sheet of ice covers a lake near the arctic circle. At the beginning of spring, the ice starts t
Digiron [165]

Answer: 1.5 meters.


Step-by-step explanation:

Given: At the beginning of spring, the ice starts to melt.

The variable s models the ice sheets thickness in meters t weeks after the beginning of spring.

s=-0.25t+4

At t=0, s=4 meters

At t=1, s=3.75 meters

∴It is a linear equation, where the rate of change in thickness = 3.75-4=0.25 meter per minute .

The decrease in ice sheet in every  6 weeks = 6\times\text{rate of decrease}=6\times0.25=1.5\ meters

Krispy Kritters Cereal used to come in a
shtirl [24]

Answer:

1335cm³

Step-by-step explanation:

The question above says that,Krispy kritters cereal used to come in a box with a volume of 2,850 cm3. However, the krispy kritters co. Designed a new larger box 22.5 cm wide, 6.2 cm deep, and 30 cm high and we are now asked to find "How many more cubic centimeters will the new box hold than the old box?

Now we are all aware that the volume of a cube or cuboid(since its a box ) is length multipled by width multiplied by the height.

And we were given the new dimensions which are;

12.5cm wide

6.2cm deep and

30cm high

Apply this given figures in the formula above and we have:

V = 12.5 × 6.2 × 30

= 4185cm³( this is the volume of the box)

Therefore,the difference in volume between the new box and the old box is

4185 - 2850 = 1335cm³
