S = D/t
120 = D / 0.5
D = 120*0.5
D = 60 km
S = D/t
70 = D / 2.5
D = 70*2.5
D = 175 miles
Answer:
7(2a - b)
Step-by-step explanation:
7 * 2a = 14a
7 * -b = -7b
Answer:
A =63.76512739 in^2
Step-by-step explanation:
The circumference is given by
C = 2 * pi * r
28.3 = 2* 3.14 *r
28.3 = 6.28r
Divide each side by 6.28
28.3/6.28 = 6.28r/ 6.28
4.506369427 =r
Now we need to find the area
A = pi r^2
A = 3.14 (4.506369427)^2
A =63.76512739 in^2
Answer:
no
Step-by-step explanation:
Answer:
Step-by-step explanation:
First, add up the two numbers in the ratio to get 8. Next divide the total amount by 8, i.e. divide £40 by 8 to get £5. £5 is the amount of each 'unit' in the ratio.
To calculate the ratio of an amount we divide the amount by the total number of parts in the ratio and then multiply this answer by the original ratio. We want to work out $20 shared in the ratio of 1:3.
