Step-by-step explanation:

A + 32 + 45 = 180 (why? Sum inside angles = 180 degrees. Proof? If you want learning proof, I show you)

A = 103

Answer:

Step-by-step explanation:

A + 32° + 45° = 180°

A + 77° = 180°

A = 180° - 77°

A = 103°

I hope I've helped you.

a country will produce 3000 missels this year. each of the short range missles costs $200,000 to produce. Each of the medium ran

guapka [62]

Answer:

Step-by-step explanation:

3000/10=300 300=10% of total missiles

300*3=900(30%) That country (assuming it is Iran) would produce 900 short missiles and 900 medium missiles. 3000-900(2)=3000-1800=1200.

Iran will produce 1200 long range missiles.

For the cost of the missiles,

200,000*900=180,000,000. 300,000*900=270,000,000.

870M-(180M+270M)=870M-450M=420M

420,000,000/1200=350,000.

Long Range Missiles are $350,000 each... got me thinkin bout buying some...

How do you determine the number of zeros to annex in the product of 0.002 and 0.003?

Marat540 [252]

0.002 x 0.003 = 0.000006

the zeroes are multiplied by the power of 10 which is 1/10 in particular.
For example.
The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that 
1. N x 0.1 = N/0.1 < N 
2. 1 x 0.5 = 0.5 
3. 2 x 0.1 = 0.2 
4. 100 x 0.55 = 55 

These three examples and stances then suggest the claim that the product is not equal to the whole number used in the equation.

miss Akunina [59]

Answer:

1,516 pounds

Step-by-step explanation:

Gorilla A weighed = 559 pounds Gorilla B weighed = 827 pounds Gorilla C weighed = 130 pounds

Total weight of the gorillas = gorilla A + gorilla B + gorilla C

= 559 pounds + 827 pounds + 130 pounds

= 1,516 pounds

Total weight of the gorillas = 1,516 pounds
