Answer:
r = 11 cm
Step-by-step explanation:
The radius is 1/2 of the diameter
r = d/2
r = 22cm /2
r = 11 cm
Answer:
B
Step-by-step explanation:
Substitute the value of (2,1) into the equations, and you find that only B works.
Answer:
Step-by-step explanation:
It's algebra really, basically make a system of equations.
1b+5j=t
3b+2j=2t
I'm gonna solve the first one for buckets so we have it in terms of jars.
b+5j=t
b=t-5j
Now I plug that into the other equation
3b+2j=2t
3(t-5j)+2j=2t
3t-15j+2j=2t
Now, since it wants how many jars are in one tub, I want to solve it so there's 1t on one side of the equation and all js on the other. or it other words solve for t.
3t-15j+2j=2t
3t-13j = 2t
3t = 2t+13j
t = 13j
So it takes 13 jars to make one tub, or one jar is 1/13 of a tub. You could then plug that in to one of the equations and find how much a bucket is.
2x-8=3x is greater than 5x-4
Answer:
$970. 19
Step-by-step explanation:
Using the compound interest formula Accrued Amount = P (1 + r)^t
where Accrued amount is to be determined
P = principal; $870
r = 3.7% = 0.037
t = number of years = 3
Therefore
Accrued amount = 870 (1 + 0.037)^3
Accrued amount = 870 x 1.037^3
= 870 x 1.1152
= 970. 19
Hence balance of the account at the end of 3 years is $970. 19
