It is recommended that there be at least 15.9 square feet of ground space in a garden for every newly planted shrub. A garden is
NISA [10]
The maximum number of shrubs (x) = a(area) divided by 15.9

a(area)=37.1*15
37.1*15= 556.5
556.5/15.9=x
556.5/15.9=35
35=x

Saleem has $20. A fish tank that he wants to buy costs $140. He earns $23 per day at a restaurant. Saleem wants to know how many
mr_godi [17]

Answer:

Since he can't work a fraction of a day, he'll have to work at least 6 days to have enough money for the tank. The inequality hat represents his situation is 23*x + 20 >=140.

Step-by-step explanation:

In order to create an inequality to this problem we first need to take the initial amount he has and sum it with the days he has to work "x" multiplied by the amount he earns each day. We then have:

saleem money = 20 + 23*x

Since he wants to buy a $140 fish tank he needs to work until his money is greater or equal than this amount. So we have:

23*x + 20 >= 140

23*x >= 140 -20

23*x >= 120

x >= 120/23

x >= 5.22

Since he can't work a fraction of a day, he'll have to work at least 6 days to have enough money for the tank. The inequality hat represents his situation is 23*x + 20 >=140.

Nina took an exam. When her results came, she had 40% correct and 68% incorrect. Find the percent to correct answers to incorrec
vivado [14]

Answer: She had 27.2% correct.

Step-by-step explanation: To find the percent, we can divide the part and whole then multiply the quotient by 100. After that we'll need to convert the percent to a decimal. In mathematical terms, the formula will be,

\frac{part}{whole}=quotient*100

40% will be the part and 68% will be the whole.

<u><em>Step 1.</em></u>

Convert 40 into a decimal by dividing it by 100.

40 ÷ 100 = 0.4

<u><em>Step 2.</em></u>

Multiply 0.4 by 68.

0.4 × 68 = 27.2

Hence, she had 27.2% correct.
