Answer:
m<EDC=110
Step-by-step explanation:
angle c is 35 degrees too, because this is isoceles
using the sum of the triangle's angles which are always 180
70+x=180
x=110
Answer:
I would say that the answer is 4/20
Answer:
B. 100
Step-by-step explanation:
(m + n)^2
= m^2 + 2mn + n^2
Rearrange
(m^2 + n^2) + 2mn
Substitute
(68) + 2*16
= 68 + 32
= 100
Answer: 6.4 feet
Step-by-step explanation:
Height of Atlas V rocket = 205 feet
Ratio of the model = 1:32 = 1/32
Model / Real = 1/32
Since Real height = 205, we put it into the equation and this will be:
Model / Real = 1/32
Model / 205 = 1/32
Model × 32 = 205 × 1
Model = 205/32
Model = 6.4 feet
The height of the model is 6.4 feet.
Answer:
Step-by-step explanation:
a1 = - 7
d = 4
an = a1 + (n - 1) * d
an = - 7 + (n - 1) * 4
an = - 7 + 4n - 4
an = -11 + 4n
Try this out. Let n = 3
a3 = -11 + 4*3
a3 = - 11 + 12
a3 = 1 Which is what the series says.
