Answer:
44yrs
Step-by-step explanation:
sum= 64
8yrs ago
Hanna = x - 8
Andrew =3x - 8
sum 8yrs ago
64 - <u>8</u> - <u>8</u> = 48 yrs
| \
Hanna's Andrew's
3x + x = 48
<u>4x</u> = <u>48</u>
4 4
x = 12
Andrew = 3x = 3 x 12 = 36( 8 yrs ago)
now = 36 + 8 = 44yrs
Hanna's = x = 12(8 yrs ago)
now = 12 + 8 = 20yrs
Priya can bike 150 m in 10 seconds
1 yd = 3 feet....so 110 yds = 3(110) = 330 ft
330 feet / 11 seconds = (330/11) = 30 feet per second
The length of the rectangle is 10 cm and perimeter of the rectangle is 32 cm.
Step-by-step explanation:
Given,
The area of rectangle = 60 sq cm
Width (b) of the rectangle = 6 cm
To find the length and perimeter of the rectangle.
Formula
The area of the rectangle = l×b
The perimeter of the rectangle = 2(l+b)
According to the problem,
l×b = 60
or, l×6 = 60
or, l = 60÷6 = 10
Length (l) = 10 cm
Perimeter = 2×(10+6) cm = 32 cm
Answer:
Laura and Rob are correct
Step-by-step explanation:
we have
39/50
1) Rob said he could divide the numerator by the denominator
so
using a calculator
39/50=0.78
Rob is correct
2) Laura said she could write an equivalent fraction with 100 as the denominator to converted into a decimal
so
Multiply by 2/2
(39/50)*(2/2)=78/100=0.78
Laura is correct
therefore
Laura and Rob are correct
