Answer:

Total cost =200+50t

Step-by-step explanation:

Given:

A cell phone plan costs`$200` to start.

Also, there is a `$50` charge each month.

To find: total cost (start up fee and monthly charge) to use the cell

Solution:

Start up fee = $200

Monthly charge = $50

Let t denotes number of months.

Total cost (start up fee and monthly charge) to use the cell =200+50t

PLEASE HELP FAST!!! Find the surface area of the composite figure. Round your answer to the nearest tenth if necessary.
aksik [14]

Using the surface area formula for rectangular and triangular prism, the surface area of the composite figure is: 444 m².

<h3>What is the Surface Area of the Composite Figure?</h3>

Total surface area = surface area of the top triangular prism + surface area of the bottom rectangular prism - area of the surface both share together.

Surface area of the top triangular prism = (S1 + S2+ S3)L + bh = (10 + 10 + 16)5 + (16)(6) = 276 m².

Surface area of the bottom rectangular prism = 2(wl + hl + hw) = 2·(5·16+4·16+4·5) = 328 m²

Area of the surface both share together = 2(16)(5) = 160 m²

Total surface area = 276 + 328 - 160 = 444 m².

2. The following triangle, ∆, has angle measures as shown.
klio [65]

Answer:

x=29. Angle C= 93

Step-by-step explanation:

3(x+2)= 3x+6.

3x+6+52+35= 3x+93.

180-93=87.

87/3= 29. So that means x=29.

for proof you can do 3(29)+93 and you'll get 180.

For angle C; 3(29+2)= 3x31. 31x3= 93.  

Angle C= 93 degrees.

Find the slope of a line perpendicular to y = -2/5x + 4/5
valkas [14]
To find a perpendicular line, you need to find the negative reciprocal of the slope.

-2/5 flips into -5/2
Since -2/5 is negative, -5/2 turns positive, so 5/2.

Therefore, the slope of a line perpendicular to Y = -2/5x + 4/5 is 5/2
