Answer:

(d) 30 units²

Step-by-step explanation:

The area of the rectangle is the product of the length and width. It is equal to the number of unit squares that fill the rectangle.

By counting grid squares or subtracting coordinates, we can see this rectangle is 3 units wide and 10 units high. Its area will be ...

A = WH

A = (3 units)(10 units) = 30 units²

_____

Additional comment

You can also count the three columns of 10 shaded squares, or the 10 rows of 3 shaded squares. Either way, you will count 30 square units covering the rectangle.

You wish to mentally estimate the total cost of items that have the following prices: $1.85, $.98, $3.49, $9.78, and $6.18. Roun

Tanzania [10]

If you wish to mentally estimate the total cost of items, rounding off the items to the nearest half dollar, then you have to consider all five items separately.

Five items cost $1.85, $.98, $3.49, $9.78, and $6.18.

1. $1.85≈$2;

2. $0.98≈$1;

3. $3.49≈$3.50;

4. $9.78≈$10;

5. $6.18≈$6.

Then the total cost is

$2 + $1 + $3.50 + $10 + $6 =$22.50.

The difference of 7 and the product of 4 and a is 11

BlackZzzverrR [31]

Product of 4 and a number translates to 4x because the word product means multiplication.
We then need to subtract one from that which would be 4x - 1.
The word is translates to "equals" so 4x - 1 = 11 is the translation of the whole problem.

Now solve that equation.
4x - 1 = 11
1st add +1 +1
2nd simplify 4x = 12
3rd divide. 4 4
x = 3
