Find the area of triangle ABC when b= 141 degrees a= 7 and c=8
Vlad [161]
  You basically use the formula height*base/2 to find the area of the triangle. For instance, let's say a is your chosen base, which has a length of 7. You then use the pythagorean theorem of the right triangle (which is formed by splitting the triangle in half), which is a^2+b^2=c^2, and you substitute half your base for a and the other length (8) for c, which is the hypotenuse of the triangle. Note how this is all being done to find "b", which is the height of the triangle, which will then help you substitute all of your known values into the area formula of a triangle to answer your question. I'm not sure if b=141 degrees would have an impact on this question, but I hope this helped you in some way.

1. Rewrite 10^32 • 10^6 using a single exponent
OLga [1]

Answer:

1. 10^(38)

2. total amount = 10^11 or total amount = $100000000000  

Step-by-step explanation:

For every time that we multiply powers with the same base we maintain the base and sum the powers. Therefore we have:

1. (10^32)*(10^6)

10^(32 + 6)

10^(38)

2. If each of the 10^6 programmers make 10^5 then the total money they make together is the product of the number of programs with the sallary each makes. We have:

total = (10^6)*(10^5)

total = 10^(6 + 5)

total = 10^11

total = $100000000000

A bicycle store costs ​$4200 per month to operate. The store pays an average of ​$75 per bike. The average selling price of each
Lelechka [254]

Store should sell about 31 bicycle for average price of $135 each bicycle.

Step-by-step explanation:

  • To find bike we need Algebra to solve the equation.
  • when x = 1 , Y = 135 *x
  • When x 2 , Y = 135 *2
  • Formula you could apply to go for break even y = 135*x
  • Bicycle store pays about $4200
  • Algebra used for every business and working to make easy task.
  • It takes about 31 bicycle a month to get into break even.
  • Every store needs break even to not incur lost.
  • Break even point is equilibrium between income and expenses.

I WILL NAME BRAINLIEST FOR WHOEVER CAN WRITE THE ANSWER! I WILL NOT GIVE IT ANYONE WHO JUST POINTS! What is the area of the figu
PtichkaEL [24]

Answer:

48.5cm^{2}

Step-by-step explanation:

This shape is actually just a rectangle with a missing triangle. We can first find the area of the rectangle with 7*8=56 and subtract the triangle.

Area of missing triangle = \frac{1}{2} *b*h (b is the base and h is the height)

Base = 8-3=5

Height = 7-4=3

Area of missing triangle = \frac{1}{2} *5*3=7.5

Area of the figure: 56-7.5=48.5

--------------------------------------------------------------------------

Alternatively, you can find the area of each individual shape and add them all up.

Area of the rectangle: 8*4=32

Area of square: (7-4)*3=9

Area of triangle: \frac{1}{2} *(8-3)*(7-4)=\frac{1}{2} *5*3=7.5

Total Area: 32+9+7.5=48.5
