Answer:
1) 37.5%
2) 27.27%
Step-by-step explanation:
q1) Pct. Increase = (82500-60000) / 60000= 0.375
Pct increase = 0.375 x 100 = 37.5 percent
q2)
Pct decrease = (44000-32000)/44000 = 0.2727...
0.2727 x 100 = 27.27%
Answer:
V = 90 cm^3
Step-by-step explanation:
The volume is given by
V = Bh
where B is the area of the base and h is the height
The base is the two sides that are identical, which is the triangle
B = 1/2 bh
= 1/2 (4*3)
= 1/2 (12)
= 6
Substituting into the volume equation, where h = 15
V = 6*15
V = 90 cm^3
Draw triangles within the ramps and since they are right triangles, use the pythagorean theorem based on what was given and solve
Answer:25
Step-by-step explanation:
Answer:
Rule: If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
Step-by-step explanation:
Your job here is to simplify 9t-4>32, in which the variable (t) is already positive. Here you do NOT switch signs or reverse the direction of the inequality symbol. Adding 4 to both sides, we get 9t > 36, or t > 4.
If, however, you had -9t-4>32 to work with, the situation would be different because t in this inequality is negative. Adding 4 to both sides results in:
-9t > 36. To solve for t, we must divide both sides by -9 AND reverse the direction of the inequality symbol:
t < -4.
Rule: If working with an inequality and you either mult. or div. by a negative number, you must reverse the direction of the inequality symbol.
