Answer:
question n.3 is a
Step-by-step explanation:
y=3x/2 + 4
2y= 2·3x/2 + 2·4
2y= 3x+8
2y-3x=8
Answer:
1. 90
2.60
3.30
4. 40
5. 80
6. 60
7. 30
8. 30
9. 120
Total for all triangles=180
Step-by-step explanation:
In all the problems, you have to solve for y. This can be done because the three angles are supplementary For example, in the first diagram, you have:
3y+2y+y=180
6y=180
y=30
It's fairly easy to solve from there. Just more multiplying and subtracting.
D. 15 m, 2m, 2.5m. it doesn’t match the triangle inequality theorem. the sum of the side lengths don’t exceed that of the third side
Answer:
option A
output = constant / input
Step-by-step explanation:
Inverse relationship between two input and output means that they both moves in opposite directions, if one increases than other decreases.
Equation to describe relationship of inverse variation between input and output will be as following
<h3> output ∝ 1 / input</h3>
to remove this sign of proportionality
<h3> output = k / input </h3>
where k is a constant
Answer:
A = 121 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi*r
22 pi = 2 * pi *r
Divide each side by 2 pi
22 pi / (2 pi) = 2 pi r / (2pi)
11 = r
Now find the area
A = pi r^2
A = pi (11)^2
A = 121 pi in^2
