Since quotient is dividing, 4 is greater than or equal to x/2.1 and 4≥x/2.1. Multiplying both sides by 2.1, we get 8.4 ≥x
Answer:
A)10.25 cm ; B)5 square cm
Step-by-step explanation:
A)
Formula:
p=(a+b+c) [p= perimeter ; a,b , and c are the side lengths.]
∴The perimeter of the triangle =(4+2.75+3.5) cm
=10.25 cm
B)
Formula:
A = 1/2 . b .h [A=area ; b= base ; h= height]
∴The area of the triangle = (1/2 . 4 . 2.5) square cm [b=4 ; h=2.5]
=5 square cm
Answer:
LCM
Step-by-step explanation:
He is finding the lowest common multiple of 12 and 15
You'd have to multiply 16 by 15.
Three 5 pound bags= 15
1 pound=16 ounces.
16x15=240
240 divided by 10=24
The answer is 24 bags of 10-ounces.
John bought the TV for . . . . $1,900
John sold the TV for . . . . . $750
John lost this much on the TV . . . (1,900 - 750) = $1,150
What fraction of the amount he paid did he lose ?
$1,150 / $1,900 = 0.6053 of the amount he paid never came back
What is this fraction as a percentage ?
0.6053 = 60.53 %
Rounded to one decimal place: <em>60.5 % </em>
John took a beating on that TV. I hope he got a lot of good use out of it while he had it.
