Answer:

See below  

Step-by-step explanation:

<em>Compatible numbers</em> are numbers that are easy to use in mental arithmetic.

Martin gave away ⅖ of 7 lb of grapes, so the amount he gave away was

⅖ × 7 lb

⅖ is close to ²/₄ (½), and it is easy to take half of something mentally.

Half of 7 is about 3, so Martin gave away about 3 lb of grapes (the exact answer is 2.8 lb).

1. Choose the description that matches the inequality. x &lt; 1
marusya05 [52]

Answer:

A line traveling to the left with an open dot on x=1.

Explanation:

The inequality x < 1 basically means "less than 1." On number lines, the further left you go, the smaller the number becomes, and the further right you go, the larger the number becomes. So we know that because it's less or smaller than 1, then the line will be to the left. On the other hand, the inequality does not have a line under it to indicate a "less than or equal to 1," just "less than." Therefore, the dot is open. If there were a line under the inequality, then it would indicate "less than or equal to 1" and the dot would be closed.

mat deposited $2,000.00 in the bank. if the rate of simple interest was 10%, what was the amount of money mat had in the bank af
Mekhanik [1.2K]
Principal amount of money deposited by Mat in the bank = $2000
Rate of simple interest given by the bank = 10%
Number of years for which the money is kept in the bank = 5 years
As no money was withdrawn from the account, so
Amount after 5 years = Principal [1 + (Rate * Time)]
                                  = 2000 [ 1 + (10/100) * 5]
                                  = 2000 [ 1 + (1/2)]
                                 = 2000 * (3/2)
                                 = 1000 * 3
                                 = 3000 dollars
So the amount of money made by Mat after 5 years will be $3000.00
