Please help me!!! (Can you also explain)
Romashka-Z-Leto [24]

Answer:

$3600 per year into savings

Step-by-step explanation:

He makes 1500 dollars a month

1/5 of that goes into saving

1/5*1500 = 300

300 per month goes into savings

We want to know how much goes into savings per year

There are 12 months in a year, so we need to multiply by 12

300 per month * 12 months/ year = 3600  per year

$3600 per year into savings

The picture below shows Annie and her younger brother Tommy’s money.
lawyer [7]

Step-by-step explanation:

Annie: 4 dollars = $4 11 dimes = 11 x 0.10 = $1.1 ( since 1 dime = 0.10 dollars)

4 pennies =4 x 0.01= $0.04 ( since 1 penny = 0.01 dollars)

Tommy 3 dimes = 3 x 0.10 = $0.3 3 pennies = 3x 0.01 = $0.03

Adding the values: 4 +1.1+0.04+0.3+0.03 = $5.47

abruzzese [7]

Answer:

The correct approach is "-62". A further explanation is described below.

Explanation:

  • A dependent variable could be seen since the blackheads become triggered whenever some substance or material is deposited between some of the teeth.
  • Humans don't brush their teeth frequently, but there is still a significant possibility of decay, so cavities differ depending upon whether the specific teeth become brushed.
