<u>Answer</u>
3×(2×5)
<u>Explanation</u>
Multiplication of numbers is associative. For example,
(a×b)×c = a×(b×c)
This is also called grouping. We multiply more than 2 numbers by grouping.
For the equation given above, (3x2)x5, it can also be grouped as 3×(2×5).
Answer: The account balance will be $6596 after 7 years.
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = $4500
r = 5.5% = 5.5/100 = 0.055
n = 4 because it was compounded 4 times in a year.
t = 7 years
Therefore,.
A = 4500(1 + 0.055/4)^4 × 7
A = 4500(1 + 0.01375)^28
A = 4500(1.01375)^28
A = $6596
Answer: 50
Step-by-step explanation:
7/10 can of cola= 1 glass.
35 cans of Sola= y
7/10 equals 0.7 as decimal
0.7 = 1
35 = y
Cross multiply
0.7y = 35
Divide both side by 0.7
y = 35/0.7
= 50
50 glasses will be filled
Answer:
The three books cost 33.50 - 9.00 = 24.50. Tom needs 24.50 more to afford all three books
Step-by-step explanation:
If it is a right triangle, it must fit the pythagorean theorem:
a²+b²=c²
We can plug in the sides to see if it works. Remember, that c is the hypotenuse and must be the longest side:
15²+36²=41²
225+1296=1681
1521≠1681
Therefore, these sides cannot make up a right triangle.
