Answer:
137.5° and 42.5°
Step-by-step explanation:
supplementary angles are two angles whose sum is equal to 180°.
Let the second angle be x then it is given that the first angle is 10 degrees more than 3 times second angle that is 3(x)+10°.
we know that the sum of first and second angles is 180° (supplementary angles)
so, (3(x)+10°)+(x) = 180°
4(x) = 170°
x = 170°/4 = 42.5°
so, first angle is 3(42.5°)+10° = 137.5°, second angle is x that is 42.5°
therefore, the angles are 137.5° and 42.5°.

Step-by-step explanation:
The Team 1 now has 15 members and Team 2 now has 8 members.
We have given that team one had twice as many workers as team two.
Let us consider,x workers in team one initially
y workers in team two initially.
we know that
Now next
We have to solve this equation by using substitution method
The substitution method functions by substituting the one y-value with the other.
Use the value of 1 in equation 2 we get
Therefore we have,
Team 1 now has 20-5 = 15 members
Team 2 now has 10-2 = 8 members
To learn more about the linear equation visit:
let
x-------> workers in team one initially
y-------> workers in team two initially
we know that
x=2y-----> equation 1
(x-5)=(y-2)+7-----> x-5= y+5----> x=y+10---------> equation 2
equate equation 1 and equation 2
2y=y+10-----> y=10
x=2*10------> x=20
Team 1 now has 20-5 = 15 members

Answer: 4
Step-by-step explanation:
Given: The length of a model locomotive = 18 inches
The length of a exact locomotive = 72 inches
The scale factor to scale the model of the locomotive is given by the ratio of the length of the locomotive to the length of the model.
let k be the scale factor, then
Hence, the dimensions of the locomotive model is 4 times the dimensions of the model.
Therefore, the locomotive is 4 times wider than a window on the model.

The volume of cylinder is 2160 .
Volume is the measure of the capacity that an object holds.
The formula for the volume of cylinder is
Where,
V is the volume of cylinder.
r is the radius of cylinder.
h is the height of cylinder.
π = 3.14
According to the given question
Height of the cylinder, h = 15 units
Radius of the cylinder, r = 12 units
Therefore, the volume of the cylinder is given by
v = π × 144 × 15
V = 2160π
Hence, the volume of cylinder is 2160 .

hello,
here is your answer:
**********
volume of cylinder = r²h
radius = 12 units
height = 15 units
volume = r² × h ×
= 12² × 15 ×
= 144 × 15 ×
= 2160 ×
ans = A. 2160 units³

hope this helped,
