Answer:
60
Step-by-step explanation:
4 = 1
1 = 60
Answer:
25
Step-by-step explanation:
5=20% of x
0.20x=5
divide both sides by 0.20
x=25
Answer:
180 cm^2
Step-by-step explanation:
For similar figures the ratio of areas is the square of the ratio of linear dimensions.
We take "tripled in size" to mean that the linear dimensions of the larger rectangle are 3 times those of the smaller rectangle. That means the area of the larger rectangle will be 3² = 9 times the area of the smaller one.
Area = (3²)(20 cm²) = 180 cm² . . . . area after tripled in size
Answer:
18
Step-by-step explanation:
√25+13= 5+13=18
Answer:
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
Step-by-step explanation:
Total cost [Pool] = Fixed (membership) cost + Variable cost (per visit)
<u>Intercept</u> is part at which equation line intersects x or y axis. In pools case, it is fixed (membership) cost. <u>Slope </u> is change in y due to change in x. In pools case, it is variable cost (per visit)
Pool K cost equation : 30 + 5V , Pool M cost equation : 10 + 10V
where V = number of visits.
Pool K slope & intercept = 30 & 5 , Pool M slope & intercept = 10 & 10
