Cost of company A=monthlyfee+text=20+0.03t where t=number of texts
A=20+0.03t

company b is monthlyfee+texts=5+0.07t
B=5+0.07t



1.
c=20+0.03t
c=5+0.07t
using c for cost is confusing because we can't tell which is for which company



2.

equal, means the costs are equal so
20+0.03t=5+0.07t
minus 5 from both sides
15+0.03t=0.07t
minus 0.03t from both sides
15=0.04t
divide both sides by 0.04
375=t
the answer is 375 texts

1. 20c + 0.03t = total
    5c + 0.07t = total

2. To find if they're equal, set them both equal to each other. Since it's one month, set c to 1.

20c + 0.03t = 5c + 0.07t
20 + 0.03t = 5 + 0.07t
15 = 0.04t
375 = t

Hope this helps!

Which expression represents the volume, in cubic
muminat

Given:

The composite figure.

To find:

The volume of the given composite figure.

Solution:

Given composite figure contains a cuboid and a pyramid.

Length, breadth and height of the cuboid are 8, 6 and 4 respectively.

Volume of a cuboid is

V_1=length\times breadth\times height

V_1=(8)(6)(4)

Length and breadth of the pyramid is same as the cuboid, i.e., 8 and 6 respectively.

Height of pyramid = 10 - 4 = 6

Volume of a pyramid is

V_2=\dfrac{1}{3}\times length\times breadth\times height

V_2=(\dfrac{1}{3})(8)(6)(6)

The volume of composite figure is

V=V_1+V_2

V=(8)(6)(4)+(\dfrac{1}{3})(8)(6)(6)

It can be written as

V=(\dfrac{1}{3})(8)(6)(6)+(8)(6)(4)

Therefore, the correct option is A.

Find cos0 where 0 is the angle shown. Give an exact value, not a decimal approximation.​
bogdanovich [222]

Answer:

cos(∅) = 3/5

Step-by-step explanation:

cos(∅) = adjacent/hypotenuse

We don't know what the hypotenuse is so we gotta use Pythagorean theorem to find it.

a² + b² = c²

4² + 3² = c²

√(4² + 3²) = c

c = 5  ,  this is our hypotenus

cos(∅) = adjacent/hypotenuse

cos(∅) = 3/5
