Answer:
The value of x is 105°
Step-by-step explanation:
Firstly, you have to find the total angles in regular hexagon and octagon using the θ = (n-2)×180° where "n" determine numbers of edges :
hexagon,
θ = (6-2)×180°
= 4 × 180°
= 720° (total angles)
octagon,
θ = (8-2)×180°
= 6 × 180°
= 1080° (total angles)
Then, calcular the angle for each edge :
hexagon,
θ = 720° ÷ 6
= 120°
octagon,
θ = 1080 ÷ 8
= 135°
Lastly, to find the value of angle x. As the angle in a circle is 360° so you have to substract :
x = 360° - 135° - 120°
= 105°
Answer:
9000 - 500m
Step-by-step explanation:
Your original number is 9000. It starts to decrease at a rate of 500 feet per minute. So we know that you will subtract 500 from 9000 but we don't know how many times. Because of this, we will put a variable to represent the minutes that we are descending.
In conclusion: 9000 - 500m
Answer:
A
Step-by-step explanation:
find there common denominator which is 40
multiply 3 by 8 and 7 by 5 to get 24 and 35
35-24=11
11/40
18-7=11
11 11/40
Answer:
x=-3,x1/2
Step-by-step explanation:
f(x)=(2x-1)(x+3)
TI find x intercept/zero substitute
f(x)=0
0=(2x-1)x(x+3)
swap the sides of the equation
(2x-1)x(x+3)=0
when the product of factors equals 0,at least one factor is zero
2x-1=0
x+3=0
solve the equation for x
x=1/2
x+3=0
solve the equation of x
x=-3
The equation has two solution
x=-3
x=1/2
Im pretty sure the answer is 7.84. i got this because 7 is a whole number so it is in the whole number spot. Then, you have to get your denominator to 100. So, what times 25 equals 100? its 4. so you get 100 so whatever you do to your denominator you do to your numerator. so 21 times 4 is 84. so 84/100 is actually 7.84. Hope this helped
