1. C
L=1/2(Pxl)
L=1/2(20x9)
L=1/2(180)
L=90
SA=1/2(Pxl)+B
SA=90+5^2
SA=115
B, A, C, B.
Answer:
it's part of the real number system
it's a rational number
it's an integer
Step-by-step explanation:
Answer: Multiplying the number by 2.5
Step-by-step explanation:
Jay took a number, n, and increased it by 25%. The value gotten will be:
= n + (25% × n)
= n + (0.25 × n)
= n + 0.25n
= 1.25n
After that, Then, he doubled the resulting product. The value now gotten will be:
= 2 × 1.25n
= 2.50n
Therefore, the equivalent will be multiplying the number by 2.5. This will be:
= n × 2.5
= 2.5n
Therefore, it's thesame with the value gotten.
The correct option is D.
Y-y1=m(x-x1) for slope=m
point is (x1,y1)
pont s (7,4)
slope is 6
x1=7
y1=4
y-4=6(x-7)
2nd one is correct answer
