Answer:
E. is 103 degree.
It's a vertical angle.
F. is 77 degree
the e and f makes a 180 degree. 180-103(aka e) = 77 degree
D. is 90 degree. it's perpendicular.
E=number of eagles
c=number of condors
ttoal is 480
c+e=480
5 times as many condors and 9 times as many eagles totals 3260
5c+9e=3260
we have
c+e=480
5c+9e=3260
eliminateion
elmiminate c
times first equation by -5
-5c-5e=-2400
add to other equation
-5c-5e=-2400
<u> 5c+9e=3260 +</u>
0c+4e=860
4e=860
divide both sides by 4
e=215
sub back
c+e=480
c+215=480
minus 215 from both sides
c=265
thiis spring is
265 condors
215 eagles
Answer:
Im pretty sure D
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Given a parabola in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the x- coordinate of the vertex is
x = - 
y = 3x² + 6x + 1 ← is in standard form
with a = 3 and b = 6 , then
= - 
= - 1
Substitute x = - 1 into y for corresponding y- coordinate
y = 3(- 1)² + 6(- 1) + 1
= 3(1) - 6 + 1
= 3 - 5
= - 2
vertex = (- 1, - 2 )
The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
From the prism:
Perimeter P = 2(w + l)
40 = 2(w + l)
w + l = 20 (1)
Also:
Base area (B) = wl
100 = wl (2)
from equation 1 and 2:
w = 10, l = 10
The dimensions of the prism has height of 7 units, width of 10 units and length of 10 units.
