Sum of angles in a triangle=180
70°+60°+(8x+2)°=180°
130°+(8x+2)°=180°
Collect like terms
(8x+2)°=180°-130°
8x+2)°=50°
8x=50-2
8x=48
x=6°
Answer:
It is choice 3
Step-by-step explanation:
Answer:
8x^6-10x^5+4x^4-5x^3-4x+5
Step-by-step explanation:
Lest distribute the expression given
this is multiply the first term (4x) with the longer expression (2x^5+x^3-1) and then, multiply the second term (-5) with the longer expression (2x^5+x^3-1).
When the above is finish, simply sum all together.
4x* (2x^5+x^3-1)= 8x^6 +4x^4-4x
-5*(2x^5+x^3-1)=-10x^5-5x^3+5
The sum of all together (respecting the coefficient they belong) is shown:
8x^6-10x^5+4x^4-5x^3-4x+5
Answer:
it requires 280 ton of wood
Step-by-step explanation:
one ship can accommodate 300 sailors so for 2100 sailors you need
2100/300
7 ships
and as I ship require 40 tons of wood then 7*40
280 tons
then
he can get 4 ton of wood per day
then
280/4
70 days
therefore he needs wood for 70 days to accommodate 2100 sailors
Answer:
10%
Step-by-step explanation:
In this question, we are asked to calculate the percentage error in a measurement.
This can be obtained by first getting the error involved. That is calculated by Subtracting the value calculated from the actual value. That is 9.5 - 8.9 = 0.6
The percentage error is thus 0.6/9.5 * 100 = 6%
The value is actually 10% to the nearest tenth of a percent
